TRIZ Forum: Contributed article: From Encountering TRIZ to Deeper Understanding (My TRIZ Learning History): Towards a Unified Methodology of Problem Solving for Resolving Various Contradictions (Dec. 5, 2011)
Youichi Hasegawa (An engineer living in Kanagawa Prefecture), Nov. 27, 2011
Nowadays, especially after the disaster of earthquake, tsunami, and nuclear plant accident, we have many and complex contradictions in Japan in its social, economical, and political aspects. For solving such contradictions, methodologies for problem solving should be penetrated and applied widely in some unified and simple-to-learn forms of techniques, Youichi Hasegawa says. For a step toward such a unified methodology, Hasegawa has contributed to this Web site an article which introduces his personal history of learning TRIZ. He encountered TRIZ and USIT in 2006 through his colleagues in his company and learned various TRIZ references, especially the ones posted and introduced in "TRIZ Home Page in Japan", for himself step by step. Reading such references, he tried to understand them with digesting and examining and to incorporate them in his understanding of problem-solving methodologies. He now has a hope of unifying currently-different methodologies, e.g., QFD, TRIZ/USIT, TOC, Hatamura's method, Breakthrough Thinking, etc., into a much simpler and universal one. This article is an excellent case study of learning TRIZ/USIT step by step and obtaining a much wider vision of problem-solving methodology. We thank Youichi Hasegawa for his contribution. In Japanese, only.
TRIZ Forum: Interview to Ayano Sato: First-time Experience of Participating and Presenting in English at International Conference, ETRIA TFC 2011, Ireland (Dec. 5, 2011)
Ayano Sato (2nd year Graduate Student, Shibaura Inst. Tech.); Interviewer: Toru Nakagawa (Osaka Gakuin Univ.), Dec. 2, 2011
As reported in a separate page, Ms. Ayano Sato attended at ETRIA TFC 2011, held on Nov 2-4, 2011 in Dublin, Ireland. She gave a very nice presentation. So Nakagawa interviewed her just after her presentation and also communicated with her via emails later. She says: She wanted (without being pushed) to give the presentation. She used to be very shy and did not like studying English language, but at her 2nd year of high school her parents arranged her to go and study at an English language school in USA for 2 weeks. During the stay she realized the necessity of communicating in English, and started to learn English for herself. She met much difficulty to pass the review process of TFC. The keyword 'Kando' in Japanese was especially difficult for her to present to the reviewer and to the audience. ('Kando' is a very deep and strong impression which moves the person later even for years.) When a number of audience said 'Nice talk!' to her, she felt much relieved and delighted. She found people at TFC talked about TRIZ much positively and widely than she learned so far in Japan, and she was impressed by aggressive TRIZ activities in Korea. -- I wish that Ayano's young and fresh heart/mind gives 'Kando' to readers of this TRIZ site in Japan. (Only in Japanese.)

TRIZ Case Study: "Problem Solving in Everyday Life: On Methods and Tools for Weeding (or Removing Weeds)" (Nov. 18, 2011)
Takahisa Miyake, Toru Nakagawa (Osaka Gakuin Univ.), 7th TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 8-10, 2011 at Toshiba Kenshu Center, Yokohama, Japan; and also Toru Nakagawa, Takahisa Miyake (Osaka Gakuin Univ.), ETRIA TRIZ Future Conference, on Nov. 2-4, 2011, at Inst. Tech. Tallaght, Dublin, Ireland. Extended Abstract:
, Presentation slides
'Removing weeds' has been a much labor work since ancient days. It appears to be a simple problem at first sight, but actually is a complex problem containing a diversity of requirements. Thus in the present study we have considered to reveal the problem in various aspects, such as purposes, goals of finishing, problem situations (e.g., ground, sorts of weeds, distributions of crops and weeds, etc.) and have thought of a variety of methods in the aspects of their intentions, tools, mechanisms, etc. and have evaluated the methods. The paper stress that before trying to solve a specific problem, we need to understand the structure of the problem from such a variety of aspects, regardless of using TRIZ or not.
Forum: From the Readers: Congratulations to the 13th Anniversary of "TRIZ Home Page in Japan" (Nov. 13, 2011)
Messages, photos, and an article received from the readers are posted here, with my thanks.
Congratulations from Iran (Messages and Photos): from Mahmoud Karimi (IIITS, Iran)
Karimi writes: 'In my institute in Iran, we have celebrated the 13th Anniversary of your "TRIZ Home Page in Japan" with our home made Birthday Cake, as shown in the attached photos'. I feel so much honored. Thanks.
A brief but valuable report from mainland China: 'TRIZ was introduced into China about 1998, but was known to only limited number of academic people for next 9 years. In 2007, the TRIZ situation has greatly changed when the Ministry of Science and Technology recognized TRIZ as the Innovation Method and started its promotion actively. Two provinces, Heilongjiang and Sichuan, became the 'Pilot Provinces' of innovation methods, and Innovation Method Society (IMS) was established under the Ministry for the purpose of research, development, and penetration of Innovation Method (i.e., TRIZ). At least three conferences/seminars in China are operated for high level communications on TRIZ, though not yet international.' PDF in English, and in Japanese translation

On the 13th Anniversary of "TRIZ Home Page in Japan": Toru Nakagawa (Oct. 28, 2011)
This Web site "TRIZ Home Page in Japan" celebrates on Nov. 1 its 13th Anniversary together with readers in Japan and over the world. This site is to promote the understanding and real usage of TRIZ by openly publishing information and communications related to TRIZ on a not-for-profit basis. Though I have been operating this site as a volunteer, this site is not a personal site but a public forum to be composed of the contributions by readers, as you see already. Most pages are published in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners. After the March 11 Japan Disaster, many people overseas sent us kind messages of prayers and encouragements, which were posted here both in Japanese and in English pages

Masao Ishihama (Kanagawa Institute of Technology), The Sixth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan; PDF of presentation slides
The Author previously developed a TRIZ-based standard process for guiding engineers to work on the Noise and Vibration Design, especially for vehicles. However, in addition to such a normal guidance, he has found the importance of showing them negative lessons, i.e., cases of misunderstanding. So he built up a knowledgebase of misunderstanding cases of Noise and Vibration design.
Minami Hamada (Kanagawa Institute of Technology), Poster presentation at The Sixth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan; PDF of Poster Introduction slides
The Author's previous idea of 'swing child seat on a spherical swivel' had a problem of no control and no damping of motion. Using TRIZ tools she found solutions of introducing an oval swivel to suppress yaw motion and a magnet for damping with the Eddy current.
Takuo Maeda (Takumi System Architects, Ltd.), The Sixth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan; PDF of presentation slides
This is an intensive and bird-view presentation on the future directions of Japanese industry, especially software industry, with a keen sense of crisis. The Author proposes a basic framework of monozukuri and has strived to integrated the TRIZ/USIT thinking into the whole process of business and technology innovation. He recently made "Workbook to Innovate Business and Technology". Onto the workbook, users write down their specific thoughts/ideas step by step under the guidance of the Workbook.

The Authors working for 'Mind Training', e.g., employee training in companies, eliminating individual’s worries, etc., have met TRIZ and incorporated it well. They have rephrased TRIZ 40 Inventive Principles into Mind Principles, and applied them to the training of people to overcome their psychological inertia. Further interesting extension of this work was presented in a Poster Session by Y. Hanaoka and H. Sanjou
Toshio Takahara ( ), The Sixth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan; PDF of presentation slides
This is a philosophical and sophisticated paper. The Author wants to explain/describe everything not only in technology, but also in human and society world, in a systematic manner. He expanded the concept of 'Objects' to be 'Everything we can recognize', thus containing not only substances, systems, ideas, etc. but also movements, changes, processes, etc. With these widened concepts, he tries to describe the 'Ideal of TRIZ' in a formal way as the transformation from the problem situations to the solutions. He suggests the importance of Radical Thinking for Enumeration as the basis for theoretical thinking. A much elaborated paper, I believe.** Note: The following Poster presentation at the Symposium has been posted already:

This presentation is Miyanishi Family's 2nd report, done by Kai (13 years old) with the guidance by his Father. They try to understand how a screw nail is magnetized with a magnet, in the words familiar for the son; thus they used the personalization, or animation. Human relationships, such as getting good friends with or giving an influence on other, are considered as the hints for designing physical experiments.

This paper is an excellent result of discussions by six coauthors having quite different specialties besides TRIZ. Their main framework adopted here is the 'Expansion of Thoughts Diagram' well-known in the field of design engineering. They have placed the role of the TRIZ Contradiction methods in this framework. They have proposed to divide the Contradiction-Matrix parameters into two groups; one group to be considered in relation to mechanism, and the other structure. Thus, they have derived two Revised Contradiction Matrices, neglecting the cross terms between the parameter groups.** For the following 4 'Special Interest Lectures', the PDF files of presentation slides have been posted publicly in the Official Web site of Japan TRIZ Society since last December. When I made individual pages of these lectures last December, I made outward links to such files. Now, for an easier access, I have restored the PDF files of the 4 lectures inside the present site, under the permissions of authors, and have made direct links. Excerpts from my "Personal Report" are also reposted in each page for easier access.

The Authors have developed a nice technical solution of Gantry Crane which can improve the throughput of loading/unloading containers with a vertical rotating system of the trolleys. The solution is demonstrated well in the simulation. However, the Authors has faced with a new contradiction in business because no one wants to take the risk of installing the idea for the first time.

An excellent record of TRIZ thinking for developing improved solution concepts further and further. The Authors learned the merits of Variable Compression Ratio (VCR) Engines, which are of course patent protected. Thus they circumvented the patents by use of Trimming, strengthen the resultant idea with 'Antidote', solved a secondary problem with ARIZ, and extended the concept further with the use of Function oriented search.

The Authors wanted to develop a software method for cloning the user's facial expression vividly onto his/her avatar in the virtual world. Two methods were known: precise Motion-capture method uses many markers and is expensive; while vision-based method is convenient without markers but in precise. The Authors' solution is to separate various feature parameters by their nature. Parameters different for each user are measured by vision and fixed beforehand, while the parameters dependent on time for a user are traced real time by the vision method. This solution is cheap, convenient, and precise.

Mahmoud Karimi got interested in TRIZ around 1999. In 2004 he started publishing a column on TRIZ and creativity every week in a newspaper and also in a weekly magazine. IIITS made a TV lecture series of 5 volumes (35 min. each) and broadcast them several times. Furthermore, since 2007, he has broadcast live TV Talk Shows more than 160 times (30 min. each) on a few TV channels. It is really amazing that TRIZ is now widely known among intellectual people in Iran!! Thus he talks about 'transfer to a new nationwide paradigm by TRIZ application and promotion'.
Nikolai Khomenko (Insight Technologies Lab, Canada), Keynote Lecture presented at The Sixth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan ; Presentation slides in PDF
OTSM was originally envisioned by Altshuller in mid 1970s and has been developed by Nikolai Khomenko since mid 1980s for extending TRIZ out of technology area into a general, area-free theory for developing tools of solving non-typical problems creatively. Khomenko's lecture summarizing his 25 years of research is introduced here with a clear framework of OTSM: (a) Key problems for OTSM, (b) Axioms in OTSM, (c) Main models of OTSM, and (d) OTSM tools. In the current stage of OTSM, complex and large-scale problems can be handled with OTSM-TRIZ Problem Flow Network (PFN) approach, Khomenko says. He also discussed about the education of creativity.
TRIZ Forum: "Current Situations and Information Sources of TRIZ".
Toru Nakagawa (OGU), written for Postscript of the Japanese Edition of Umakant Mishra's Book: "A Collection of Problem Solving Ideas in IT and Software Technologies -- Classified with TRIZ Inventive Principles --"
This article is written for people coming new to TRIZ. The basics of TRIZ concepts are assumed to be read elsewhere, say the Introduction by Umakant Mishra. I introduce the current situations of TRIZ in the World and in Japan, and show information sources in TRIZ. In the latter part several excellent papers of application and promotion case studies are introduced by using recent presentations reported at Japan TRIZ Symposia.
Announcement: Japanese Translation Project of Umakant Mishra's IT & TRIZ Book (3) Japanese Edition Completed!! Will Be Published Soon.
Toru Nakagawa (OGU) and Masatoshi Hotta (SKI) ,
The Japanese Translation Project of Umakant Mishra's TRIZ & IT Book has now completed, after 4 years of struggling, its Japanese Edition, including an elaborated hierarchical Index of IT terms. We are now negotiating with the author and preparing for the publication. "A Collection of Problem Solving Ideas in IT and Software Technologies -- Classified with TRIZ Inventive Principles --". During the coming Japan TRIZ Symposium, Sept. 8-10, 2011, a sample of the new Japanese Edition will be displayed for sales promotion.
A wide variety of IT/Software techniques are collected and their essence of ideas are classified with TRIZ 40 Inventive Principles. A lot of interesting cases are described for IT/SW engineers and users. If you read this book while having some problems/tasks in your mind, you will find a number of hints. For readers more or less familiar with TRIZ, the way of adapting/extending TRIZ to the new field, IT/SW, will be helpful for applying TRIZ to your own field of problems. TRIZ has now certainly covers the IT/SW field. In this site we posted: Preface (II) by Nakagawa

Forum: Current Situations in Japan after the March 11 Disaster: Information Sources and Notes (Posted: May 19, 2011)
Toru Nakagawa (Osaka Gakuin Univ.), May 18, 2011.
This page intends to summarize the Current Situations in Japan after the March 11, 2011 Disaster. Since there are a large variety of issues you want to know and the situations are changing rapidly, I will show you some references and information sources rather than try to write down the situations in detail. Recently Japanese Government has posted a report: "Japan’s Challenges Concerning the Domestic and International Implications of Fukushima Dai-ichi Nuclear Power Station" (METI, May 12, 2011). It is a comprehensive and facts-based report covering most of the issues you would like to know. Thus I have introduced it and illustrated a map of Japan, for showing the locations of the Quake center, Tsunami area, Fukushima nuclear plant, and Tokyo & Yokohama. In short, even though the process of cooling down the nuclear plants needs some more months and careful watching, the general situations in Japan are getting recovered and everyday life of people in Japan are safe and active as usual except in the restricted area (20 km range) around Fukushima Nuclear Plant. Thus we are now almost confident to be able to hold the TRIZ Symposium in September without troubles.

Japan TRIZ Symp. 2010 Paper (Invited Lecture 4): "Education with TRIZ: For New Perspectives" (posted: Dec. 30, 2010)
Toru Nakagawa (Osaka Gakuin University), Special Interest Lecture 4, presented at The Sixth TRIZ Symposium in Japan 2010, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), written on Dec. 25, 2010 in 'Personal Report of Japan TRIZ Symposium 2010.
TRIZ in Japan has been promoted mostly to engineers in industries but it should also be important and useful to introduce TRIZ into the education of younger people including university students to children. For this purpose, the Japan TRIZ Society recently started the 'Education with TRIZ' Study Group. The present lecture discusses the perspectives of education with TRIZ. The first aspect is the introduction of TRIZ into the education (and research) in universities and graduate schools. I have shown a number of case studies in Japan (including my own) and overseas. The education of university students should be carried out with the consideration of differences in their background from engineers. Thus, instead of 'teaching TRIZ', we should better teach the thinking ways with TRIZ and related methodologies in a wider scope. There are various pioneering case studies available for reference. The second aspect is the introduction of TRIZ into the secondary/elementary education. For this purpose, we have to be very thoughtful about the maturing processes of students/children and adapt the contents and styles of teaching to the students/children so as to make them attractive and comprehensible. Japanese TRIZ community is still poor in the experiences of education at such levels, and hence should collaborate with people/organizations who have been working for creativity and science/technology education outside TRIZ.

Japan TRIZ Symp. 2010 Paper (Invited Lecture 3): "Intellectual Property Strategy of TRIZ Usage and Practice" (posted: Dec. 30, 2010)
Toshimitsu Kataoka (Patbrain, Co., Ltd.) [English translation by Kyoko Miyashita and Kazushi Tsuwako (Hitachi GST)]], Special Interest Lecture 3, presented at The Sixth TRIZ Symposium in Japan 2010, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), written on Dec. 22, 2010 in 'Personal Report of Japan TRIZ Symposium 2010
Since 1970s the Author has been interested in inventive thinking and IP strategies as an engineer and IP member for Anritsu Corp., and after his age-limit retirement as a consultant. The Author is pointing out the problem that most IP people who know TRIZ more or less regard TRIZ merely as the method for technical problem solving and do not realize the significance of TRIZ as essential means for IP strategies, or even more as the means to unify business strategies, R&D strategies, and IP strategies together, as Prof. Kenichiro Senoo advocates (without mentioning TRIZ).
The Author presented two case studies of his own IP activities at Anritsu. One is related to the invention of 'nonlinear numbers and punched holes' for indicating the remaining amount of telephone cards. After 16 years of struggling, this simple idea obtained a very profitable patent. The second is related to the LCR (Least Cost Routing) device/software invention at the days of deregulation of telecommunication networks in Japan. It is now well known that Mr. Masayoshi Son, President of Softbank, made LCR inventions in 1986 and succeeded in building up his big business. As a matter of fact, however, Anritsu applied a fundamental LCR patent in 1985 and obtained the patent approved. Thus Anritsu started a negotiation of licensing. But the negotiation was stopped without getting royalty, because Anritsu did not have a plan in the network business, the Author says. Softbank had a strong mind with business-R&D-IP strategies whereas Anritsu did not have any strategy in business, R&D, and IP in relation to the LCR invention. The Author discloses these interesting case studies after 20+ years.

Japan TRIZ Symp. 2010 Paper (Invited Lecture 2): "TRIZ for Managers -- Approach and Management Using Scientific Methods --" (posted: Dec. 30, 2010)
Kazuya Yamaguchi (MOST, LLC) [English translation by Yoshihisa Konishi], Special Interest Lecture 2, presented at The Sixth TRIZ Symposium in Japan 2010, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), written on Dec. 14, 2010 in 'Personal Report of Japan TRIZ Symposium 2010
During 2001-2007, the Author promoted the company-wide introduction and application of 'scientific methods' at Panasonic Communications Co., and after his age-limit retirement he has been working as an consultant. As the 'scientific methods' for product development, the Author recommends the following four methods: (a) QFD for revealing the right targets to develop, (b) TRIZ for solving the technical problems which are prohibiting the achievement of the targets and for creating solution concepts, (c) Taguchi Method for implementing the solution concepts by revealing the design parameters which minimize the quality variation, and (d) Computer assistance like CAE/CAD/CAM which makes the whole process of design verification to manufacturing speedy and easy. The Author puts much stress on the introduction/promotion of not TRIZ alone but these four methods together. Application of TRIZ is effective because we apply it to the right targets and right problems revealed by QFD at the preceding stage; and we are safe in generating new and creative solution concepts because we have Taguchi Method and CAE, etc. at the subsequent stage, the Author says. "Scientific methods (QFD, TRIZ, Taguchi Method, etc.) are tools for gaining profit, business operation itself, and management itself!", he says. In more concrete words, he advises managers to tell their members: "Utilize the scientific methods!" in pace of 'Play full out!' or 'Give it your all!'; "Bring me the result of QFD review!" in place of 'Review closely'; "Show me ideas generated with TRIZ!" in place of 'Combine the wisdom of all!'; and "Bring me the data of Taguchi Method review!" in place of 'Reduce defects radically!'. -- This lecture gives us very clear and powerful messages.

Japan TRIZ Symp. 2010 Paper (Invited Lecture 1): "Application of TRIZ for Product Planning – Development of Innovation-oriented TRIZ –" (posted: Dec. 30, 2010)
Manabu Sawaguchi (Waseda University, Graduate School of Creative Science and Engineering), Special Interest Lecture 1, presented at The Sixth TRIZ Symposium in Japan 2010, Held by Japan TRIZ Society on Sept. 9-11, 2010 at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), written on Dec. 8, 2010 in 'Personal Report of Japan TRIZ Symposium 2010
The Author moved last April from SANNO Univ. to Waseda Univ. For Japanese manufacturing industries to run on the leading edge in product development, it is important to develop systematic innovation approach, and to develop and promote 'innovation-oriented TRIZ', the Author says. He found best three of recent "Big Hit Products" in Japan were E-money, iPod, and Wii, and he studied the innovative nature of them. He also considers the relationships among mega-trends in contemporary Japanese society and discusses about the method to grasp latent functional requirements and latent contradictions. On the basis of these discussions the Author temporarily concludes as: "The approach for matching the technology development (or evolution) toward the society evolution is important. Namely, in the creation stage of innovation, matching the technology toward the trends of near-future society seems to be the key to success, while the technology to be matched may be either application of existing technologies or challenges of new technologies; the origin of the technology may not be so essential in this relation."

In my Personal Report I am going to review all the presentations given at Japan TRIZ Symposium 2010
Mahmoud Karimi (IIITS, Iran) talked on "TRIZ Activities in Iran". He got interested in TRIZ around 1999. In 2004 he started publishing a column on TRIZ and creativity every week in a newspaper and also in a weekly magazine. IIITS made a TV lecture series of 5 volumes (35 min. each) and broadcast them several times. Furthermore, since 2007, he has broadcast live TV Talk Shows more than 160 times (30 min. each) on a few TV channels. It is really amazing that TRIZ is now widely known among intellectual people in Iran!! Thus he talks about 'transfer to a new nationwide paradigm by TRIZ application and promotion'. See
Nikolai Khomenko (Canada) gave a Keynote Lecture on "OTSM (General Theory on Powerful Thinking)". OTSM was originally envisioned by Altshuller in mid 1970s and has been developed by Nikolai Khomenko since mid 1980s for extending TRIZ out of technology area into a general, area-free theory for developing tools of solving non-typical problems creatively. Khomenko's lecture summarizing his 25 years of research is introduced here with a clear framework of OTSM: (a) Key problems for OTSM, (b) Axioms in OTSM, (c) Main models of OTSM, and (d) OTSM tools. In the current stage of OTSM, complex and large-scale problems can be handled with OTSM-TRIZ Problem Flow Network (PFN) approach, Khomenko says. He also discussed about the education of creativity.

This paper reports the activities at Nakagawa's Seminar Class of 2nd year students (of 10 members) at the Faculty of Informatics. The class was designed to study basic TRIZ concepts without using TRIZ terms nor TRIZ tools. Nakagawa gave no lecture but questions and tasks onto the students, and the students answered them, made exercises and a report together. Students have surveyed a large variety of writing instruments and classified them with respect to their writing mechanisms. They also listed up various needs/usages of them and evaluated different writing mechanisms with respect to these usages. This way of learning would be applicable to even younger students (of age over 10). At TRIZ Symposium Nakatani (2nd year student) gave a poster presentation, while at ETRIA TFC Nakagawa gave a Short Paper presentation.

On the 12th Anniversary of "TRIZ Home Page in Japan": Toru Nakagawa (Oct. 27, 2010)
This Web site "TRIZ Home Page in Japan" celebrates on Nov. 1 its 12th Anniversary together with readers in Japan and over the world. This site is to promote the understanding and real usage of TRIZ by openly publishing information and communications related to TRIZ on not-for-profit basis. Though I have been operating this site as a volunteer, this site is not a personal site but a public forum to be composed of the contributions by readers, as you see already. Most pages are published in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners. I envisage that Pubic Web Sites built in different TRIZ Communities will form A Global TRIZ Community with much reduced language barriers
Forum: From the Editor: "Global Network of Public Web Sites in TRIZ: A Proposal for Building A Global TRIZ Community (3) " (Oct. 27, 2010)
Toru Nakagawa (Osaka Gakuin Univ., Editor of the "TRIZ Home Page in Japan"), ETRIA TRIZ Future 2010 Conference, Poster, To be held on Nov. 3-5, 2010, at Univ. of Bergamo, Bergamo, Italy
This is a vision and proposal for building a Global TRIZ Community effectively. My proposal is: (1) Let's build many Public Web sites in different TRIZ communities, and (2) set both outward-looking and inward-looking windows on them for overcoming the language barriers, and (3) form an autonomous global network of them in the Internet. I obtained this vision through the 12 years of operation of this Web site "TRIZ Home Page in Japan", and advocating the proposal since 3 years ago.

This paper is a report of Nakagawa's Seminar class in Faculty of Informatics. The group exercise of problem solving with TRIZ/USIT done in the second semester of the 3rd year class is reported by Yutaro Ueda, the student. The problem is familiar. We need some form of hints for recalling the passwords, but the hints must not allow malicious people to guess the passwords. Using the USIT procedure and TRIZ 40 Principles, the problem was solved to give solution strategies.

Introduction (in English) by Toru Nakagawa (Osaka Gakuin Univ.) (An excerpt from 'Personal Report of Japan TRIZ Symposium 2009' posted on Feb. 4, 2010)
This paper contain several important and interesting views: (a) On the basis of discussions on the complementing roles of explicit knowledge and tacit knowledge on learning and inheriting culture, the Author tries to characterize education systems. (b) From such a viewpoint, the Author characterizes the education systems in Japanese history, especially in the Edo era, Meiji to Pre-war era, and Post-war era. He finds the weight of explicit knowledge is getting larger. (c) In the era when lessons of drastic historic experiences form a strong basis of tacit knowledge among a nation and new explicit knowledge is introduced later, a big rise of new culture occurs. (d) Viewing TRIZ as a case of western culture, the weight of explicit knowledge typical in its knowledge bases seems large. (e) Lessons of Japanese history suggest that a new rise of experiencism, or putting more emphasis on tacit knowledge in education, is desirable or needed for Japanese culture in near future.

The Author is the leader of 'Miyagi TRIZ Study Group', which has been working to penetrate TRIZ into local industries including SMEs. For supporting TRIZ beginners to apply newly learnt TRIZ methods to their problems, the Author has developed simple tools. The most popular one among them is the "9windows" tool to be used in the idea generation meeting for new product development. It is like a 'white map' of 9 windows, having the framework and simple remarks.

Introduction (in English) by Toru Nakagawa (Osaka Gakuin Univ.) (An excerpt from 'Personal Report of Japan TRIZ Symposium 2009' posted on Feb. 4, 2010)
On the first day afternoon of the Symposium, Ms. Minami Hamada, a first year MC student, presented the paper vividly and impressively. And the presentation won the Award as the results of the voting by Japanese participants. So I wanted to introduce this paper closely in my "Personal Report", but actually my introduction was very brief. At the stage of submitting the final manuscript, after Professor Ishihama made the English translation, Ms. Hamada further revised the Japanese slides for herself. Since I found the revised Japanese version much improved, I wrote my Personal Report just briefly so as to be enhanced later by getting the revised English slides. Unfortunately one year passed while Professor was too busy to revise the English version. Thus I post the presentation documents as they are.

I believe this case study has given a very interesting and useful solution to a confusing problem in an equipment which tests the performance of electric circuit boards. Unfortunately, however, I do not understand well the problem situations and the achieved solution. The Authors' solution is called 'Outside in', i.e. a black-box type testing, but I do not understand well how the test is performed and the test information is obtained. In introducing this paper, I have used the Authors' description in Extended Abstract directly (inside ' '), for avoiding from making further confusion. Someday I would like to make a better introduction with the help by the Authors.

Introduction (in English) by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009' posted on Dec. 24, 2009
This paper aims at analyzing a number of new technologies familiar to us with the eyes of USIT and accumulating them in a collection of case studies. The analysis puts much emphasis on the close observation of mechanism/process of the problem system and on the understanding of the root causes. The Authors classify the problems into 4 classes, i.e., A: Excess of function, B. Insufficiency of function, C: Instability of function, and D: Harmful effects, and further into 16 sub-classes in accordance with the generalized categories of root causes. In the analysis of case studies, the Authors try to assign the essence of inventors' ideas in terms of the USIT Operators (i.e. a set of 32 sub-operators derived from all the idea generation methods in TRIZ). In this manner, the Authors are developing an Index Matrix where appropriate frequently-used USIT Operators can be obtained for each type of problems. In comparison to the Altshuller's Contradiction Matrix, the USIT Index Matrix is much more generalized (i.e. only 16 problem types in place of 39x39) and straightforward.

The paper overviews the history of introducing TRIZ in Korea, and states that TRIZ in Korea is now at the stage of rapid growth of the S-curve. The most important trigger of the growth was the successful technical case studies achieved in Samsung group companies by the Russian TRIZ experts around (or just before) 2004 and the fact that the managements of the big companies recognized them and promoted TRIZ actively. Then the needs of training engineers in the companies led to the effective use of on-line training courses. According to the Author, many books on TRIZ were published in the Korean language, and several universities have started the regular classes on the subject of creative engineering design on the basis of TRIZ. The Author summarizes 9 main success factors of TRIZ promotion in Korea.
In Nakagawa's Personal Report, I briefly discussed on the current situations of TRIZ activities in Japan from K.W. Lee's 9 viewpoints plus 6 more different ones

This is an excellent work based on an intensive wide-scoped research for many years and has been posted and used in their intranet home page. 'Monozukuri' is the Japanese word for 'making things' in a wide sense, including all the processes of planning, designing, manufacturing, production, etc. The Authors have built an Index Matrix for finding useful methods/tools from the current phases of jobs of Monozukuri. The key idea of making the Index Matrix is to list up the engineers' intentions/questions along the phases of the whole Monozukuri process. The table is as big as (37 questions) x (73 methods/sub-methods). 8 methods are listed in TRIZ and another in USIT. The Index Matrix contains a very rich information about many methods and their effectiveness evaluation. This presentation obtained the 'Best presentation for myself' Award after the voting by Japanese participants. It is indeed a valuable contribution, I believe. We wish that the Authors publicize the full contents of the Index Matrix, so that the contents will be validated and refined by many people.

The Authors have promoted TRIZ in the Corporate R&D Division of Panasonic Corp. since 2003 and have applied TRIZ to 156 real projects of their jobs in the IT & Software field. Questionnaires were carried out at the end of each TRIZ application project, and their answers written in a free format have been analyzed in the present paper. The engineers' answers well address the keypoints and are mostly positive. The number of patents issued by each employee every year was also examined and demonstrated the fact that the employees who had TRIZ experiences (together with their senior colleagues) in their first year of employment have produced much larger number of patents in the 2nd and 3rd years of employment than those without such TRIZ experiences.

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009', posted on Dec. 24, 2009
As the goal of a regional (i.e. sub-national) integrated energy planning, the project states that the plan must be "environmentally friendly, technically reliable, institutionally sound, socially acceptable, cost-effective, and supporting long-term regional sustainable development". The project must manage a complex and large-scale task which involves not only technical issues but also social, economic, and many other issues. The present paper has introduced the OTSM-TRIZ methodology as the framework of planning. OTSM-TRIZ is a further extension of TRIZ, started by Altshuller and later developed mostly by Nikolai Khomenko. The present paper serves as an nice introduction to the OTSM-TRIZ.
The methodology aims at understanding the complex, large-scale problem in the framework of Altshuller's powerful thinking, representing the routes from the reality to most desirable solutions with a network flow diagram for revealing the barriers or contradictions, and solving those contradictions with TRIZ. They also have a practical overall process model for preparing, analyzing, prioritizing & decision-making, and implementing & monitoring, in the cooperation with other groups of people including decision makers.
This paper may be useful for you to learn about OTSM-TRIZ before the coming lectures by Nikolai Khomenko: Keynote Lecture at Japan TRIZ Symposium 2010 (on Sept. 9-11) and one-day lecture in "OTSM-TRIZ Introduction Seminar" (on Sept. 8, 2010).

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009', posted on Dec. 6, 2009
Panasonic Communications Company (PCC) introduced TRIZ since 2001 and has been actively used the integrated set of scientific techniques including QFD-TRIZ-Taguchi Method (as well as CAD/CAE) in a company-wide scale. It is perhaps the company where TRIZ has been applied most actively and widely in Japan. Nevertheless, engineers in development projects are apt not to use such TRIZ-based scientific techniques because of being too busy to apply them in their orthodox forms. Thus the Authors made the methods 'scalable' corresponding to the demands of the projects and easier to apply. The new method has a process of 3 main phases: (1) First, to generate many fundamental (or preliminary, existing) ideas of functions and to make a tree-style Function Map. (2) Then, to select the areas for addressing the solution efforts and to force the members to create new/inventive ideas in managed brainstorming sessions. (3) Finally, to evaluate various ideas generated so far and to enhance the highly-evaluated ideas by combining subsidiary ideas, thinking deeply, and looking from competitors' eyes, etc. and to make them the solutions for possible implementation and patent filing. This method, though not appearing like a TRIZ any more t first sight, is firmly underlaid by TRIZ. The industrial TRIZ practitioners have really digested TRIZ into a new form for real applications. This paper won the Award of 'Best Presentation For Me' as the results of Japanese participants voting at the Symposium.

S. Saleem Arshad (Applied Innovations, Australia), Contributed on May 6, 2010 ; Japanese translation by Toru Nakagawa (OGU) on May 8, 2010.
This is a very valuable article containing a lot of important issues which need to be discussed. The Author writes in the Abstract as: "Increasing global emphasis on innovation as an agent of change and recovery from the economic crises, places new demands on the development of advanced tools for technical innovation. Four contributing causes for the apparent lack of success of TRIZ in mainstream usage are identified and examined. Consequently, eleven aspects are presented to highlight a way forward for TRIZ and for the overall field of innovation sciences."
I wish many TRIZ leaders in the world to read this and respond to it if possible. My brief comments on this article are posted at the bottom of the article.

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009', posted on Dec. 24, 2009
The Authors introduced TRIZ together with QFD and TM and applied them to the real project of developing a new product, i.e. a high-speed response pneumatic air valve. They have tried to capture real voices of customers with QFD. The technical problems thus assigned were challenged by the Authors with TRIZ. Some of the new solution concepts obtained with TRIZ were beyond their experiences and expertise. Thus for minimizing the risks in the new product development, they applied TM (Taguchi Method) in designing the test parameters and used CAD/CAE software for the simulation testing of various design choices. The report describes details of the newly developed product, in its performance, inner structure, cases of applications, etc.
The three methods were all new at first to the Authors and to the company, they report. They requested only one Japanese consultant to instruct all the three methods and to coach the project throughout the course. This presentation obtained "The best presentation for me" Award by the voting of Japanese participants during the Symposium. Congratulations!
TRIZ Forum: Collabo: "Collaboration Pages with the Promoters of TRIZ and Related Areas" Are Started. (posted: May 9, 2010)
From the Editor (Toru Nakagawa): New categories of pages are now started in Japanese. Several Japanese promoters of TRIZ and related areas are going to contribute (relatively) short articles regularly or from time to time. For each contributor an HTML page will be operated for posting his/her articles in a cumulative manner. The readers who are interested in the articles will visit the contributors' original Web site or Blog site. Thus a collaborative network of promoters' Web sites will be formed with stronger connections that simple mutual hyperlinks; The "TRIZ Home Page in Japan" is going to serve as the Hub. The following pages are now open:

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009', posted on Nov. 23, 2009
This Keynote starts with the questions 'why more than 90 % of projects fail to deliver their products to the market' and 'why more than 90 % of products fail in the market'. The Author's main postulates are 'Innovation happens when the Voice of the customer matches with the Voice of the system', and 'Understanding the Voice of the customer is crucial for the innovation, but TRIZ lacks in such a method'. Thus he proposes a new general scheme for revealing the real Voice of the customer, on the basis of his team's 8 years of research. It has 3 steps: (1) To identify the desired functionality. (2) Combination of (a) to understand the change in population, (b) to understand the characteristics of the generation of customers, and (c) to consider the characteristic behaviors of customers. (3) To understand many relevant trends of the market and the enforcing and conflicting relationships among such trends, and finally to consider the desires of solving the contradictions between trends as the Voice of the customers. The Author tries to make this scheme general by adopting some 'Theories of Everything'; particularly Generation Cycles in (2b) and Spiral Dynamics in (2c) and by considering 1000 trends in (3). The Author's endeavor to distill the essences from numerous methods and business books is amazing, and has resulted an interesting presentation of all insights at one place in the form borrowed from the Periodical Table of Atoms. An excellent lecture from which we can learn a lot.
Forum: TRIZ Activities in Iran (2) Applying TRIZ for Promotion of TRIZ (Mahmoud Karimi (Iran) ) (Mar. 24, 2010)
Mahmoud Karimi (IIITS, Iran), Mar. 24, 2010; Japanese translation: Toru Nakagawa, Mar. 24, 2010
Following the overall report posted a month ago, Mr. Karimi has written for us about the stories how he introduced TRIZ in Iran. The initial stage of learning TRIZ in Iran and how he organized the first TRIZ Workshop by Russian specialists (in 2001). Then, instead of repeating meetings with managers at basic levels, he shifted his efforts for writing a column "Innovation Elixir" weekly in a popular newspaper (in 2004). Vivid stories full of much insights.

Mahmoud Karimi (Iranian Institute of Innovation and Technology Studies (IIITS), Iran), Dec. 8, 2009; Japanese translation by Toru Nakagawa (OGU). Feb. 20, 2010.
This is a two-page communication outlining how TRIZ has been introduced and penetrated into Iran. The country where people do the most internet search on TRIZ is Iran, to our surprise. TRIZ has become a known term among educated people in the country, the Author says. Introduction of TRIZ in Iran started in 1999 by Prof. H. Salimi's group in the university, and led by IIITS (where the Author is the Vice President) since 2001. They invited a number of TRIZ Masters for training, and they published books, performed consulting and trainings, etc. It is remarkable that they have used mass media effectively; a series of 5 TV programs were made and broadcast three times already, and interviews and discussions on TRIZ were broadcast in popular TV talk shows. ... We are very much looking forward to the Author's vivid Keynote Lecture
7 photos provided by Mahmoud Karimi are inserted in this page. Most of them are taken from TV programs. (Mar. 13, 2010).

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
Paper printed in the Proceedings both in English and in Japanese, but not presented because of the author's absence. This paper poses a question: "TRIZ certainly helps us solve difficult problems containing contradictions. Such inventive solutions, however, can smoothly pass the prosecution process of patent application? TRIZ guides us to use various models, especially Inventive Principles and various examples in other fields. Does this mean we are relying on prior arts? Is there any risks that IPO examiners regard our inventive solutions obvious with respect to prior arts?" -- The Author demonstrates a case study of an inventive patent application in the field of functional textile design and examines its patentability with respect to the prior arts. His conclusion is: "Which methodology (e.g. TRIZ) is used during the problem solving is not a matter in the patent prosecution process. Novelty or unobviousness matters with respect to the prior arts. Thus (inventive) solutions obtained with TRIZ have to be examined in this viewpoint before the patent application. You have to search prior arts and limit your claims carefully to obtain patent protection." Nakagawa has translated this fine paper into Japanese.
Japan TRIZ Symp. 2008 Presentation: "Usage of TRIZ and USIT in Developing a Novel Duplex Printing Machine"
Hiroshi Kanno (Tohoku RICOH Co., Ltd.), Presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
This is an excellent case study paper which reports on the development of a duplex printing machine 'RICOH Satelio Duo 8' with the help of TRIZ and USIT. The digital duplicator uses the mimeography, which uses the pseudo drying of printer ink due to penetration into the paper fibers. Thus the paper having printed fresh on a side can not be printed on the other side without making the printer roller dirty. This problem has long made a dual printer impossible. On learning basic TRIZ, the Author got the idea of using only one printer drum for printing the both sides and challenged the development of the dual printer. After various trials, the SLP modeling helped to solve the dirty-ink problem by developing a beads-roller. Author also learned USIT later and used it for solving many subsequent problems. The new dual printing machine thus developed with relatively simple modifications has doubled the throughput. -- This presentation has won the Award by the participants voting. The Japan TRIZ Society is requesting the company for the permission to post the full set of presentation slides publicly in its Web site, but has not obtained it yet. Nakagawa has translated his introduction to this paper into Japanese and is posting here.
Japan TRIZ Symp. 2008 Presentation: "Application of TRIZ to Noise and Vibration Problem Solving -- Fusion with Traditional Theoretical and Empirical Approach --"
Masao Ishihama (Kanagawa Institute of Technology), Presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Slides in PDF in English
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
The Author writes in the Abstract: "Conventional textbooks on noise and vibration (NV) control almost always describe analysis methods only and don’t provide methods of solving problems. On the other hand, handbooks contain solutions of “specific” problems, but they don’t necessary give readers solutions to general problems. In this study, the author tries to connect NV theory with TRIZ idea of solving problems for giving engineers rules of thumb of NV technology. This method converts specific concrete problems into abstract general problems by sorting symptoms by frequency, time dependency, etc. Then these general problems are placed in suitable categories classified by equation of motion in NV theory. Then rules of thumb described with problem solving manner is given." The paper of this work has been accepted for publication in International Journal of Vehicle Noise and Vibration (IJVNV). Thus the presentation slides are now posted here in English and in Japanese.

Toru Nakagawa (Osaka Gakuin Univ.), Dec. 24, 2009
7 Contributed presentations are reviewed. Yojiro Fukushima et al. (Panasonic Corp.) has reviewed the acceptance of TRIZ by their engineers through 156 real projects in IT/software field and has shown that the engineers who were in the TRIZ application projects in their freshman-year produced much more patents during their 2nd and 3rd years in comparison with the engineers without TRIZ experiences. Tomohiko Katagiri et al. (Koganei Co.) introduced and applied QFD-TRIZ-TM (Taguchi Method) in an integral way to the development of new products. They developed a novel air valve which satisfies the customers' requirement of very high-speed response, is made possible by new design of solenoid achieving good performance and high robustness and reliability [an Award winning paper]. Atom Mirakyan et al. (EIFER, Germany) reported an integrated energy planning project achieved by implementing a methodology supported by OTSM-TRIZ. This is a useful model for tackling a large-scale complex problem which needs not only technical problem solving but also social/ecological decision making. KyeongWon Lee (Korea Polytech. Univ.) reported the TRIZ activities in Korea, saying TRIZ is in its rapid growth stage in Korea. In response to Lee's 'success factors in Korea', Nakagawa evaluates the current TRIZ situations in Japan.

Toru Nakagawa (Osaka Gakuin Univ.), Dec. 5, 2009
10 Contributed presentations are reviewed. Takahiro Shoji et al. (Panasonic Comm. Co.) has developed a 'scalable' process by unifying QFD-TRIZ-TM methods almost at the 'implicit' level and applied it to a real project of new product development from problem setting to idea generation to patent application. Intel Malaysia has delivered four real case-study presentations, to our great pleasure. They solved the problems of (1) stabilizing the ionizer equipment, (2) leakage detection of coolant, (3) making easy to maintain a handler, and (4) testing the S/N ratio of digital devices from outside; they seem to use rather basic TRIZ tools effectively and have achieved useful /beneficial results. Takuo Maeda et al. (MPUF USIT/TRIZ Study Group) has developed a Workbook of USIT applicable to SW/IT problems; they are going to use the Workbook for generating ideas of new SW/IT systems.

3 Contributed presentations are reviewed in this category. Toru Shonai et al. (Hitachi) reported a survey on 'Thinking Methods for Invention and Discovery', with emphasis on Japanese-origin methods. Osamu Kumasaka et al. (Pioneer) also reported an extensive survey and has shown a very useful Index Matrix for referencing from tasks in the Monozukuri (or the whole R&D and manufacturing) process to various methods/tools for engineering and problem solving in a wider sense. The Matrix is of size 37×73, and has been used in the intranet.
TRIZ/USIT Case Study: "How to Prevent Cords and Cables from Getting Entangled: A Study of Systematic Classification of Various Solutions" (Nov. 23, 2009)
Toru Nakagawa, Tomoyuki Itoh, and Masanobu Tsukamoto (Osaka Gakuin University), Presented at Fifth TRIZ Symposium in Japan, Held on Sept. 10-12, 2009 at National Women's Education Center (NWEC), Saitama, Japan; and also presented at ETRIA "TRIZ Future 2009" Conference, Held on November 4-6, 2009 at The Polytechnic University of Timisoara, Romania.
This paper is an extension of my students' thesis works. Cords and cables often cause troubles by getting complex and entangled. Instead of trying to find some specific solutions to this common widely-spread problem, we thought it worthwhile to collect many known solutions and to systematize them. We collected various solution examples and then tried to classify them in terms of their functions. A system of solutions achieved by a bottom-up classification, however, was not found convincing, so we needed a more systematic approach. Introduction and extension of the scope of system was found useful. The scopes of (A) a single cord/cable, (B) multiple cords/cables, (C) connecting parts between cords/cables and devices, and (D) the whole system with cords/cables and devices were considered step by step. This approach has provided a consistent system of known solutions, and has given us some clews to think further ahead. The English page holds the full paper in HTML

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
The Author, Darrell Mann, has been working on the intensive analysis of all the US (1985 - today) patents since 2000 (initially at CREAX and currently at SI). The information extracted from the patents are used to enrich an update TRIZ knowledge bases, mostly related to the trends of evolution, functions, and contradictions. In the present paper the Author summarizes the results of the analysis of patents granted in 2006-2008. Analyzing 100 patents in the scheme of Contradiction Matrix, he has found the effectiveness (for suggesting appropriate/relevant Inventive Principles) of the Contradiction Matrix to be 18 % for the Classical Matrix while 96 % for Matrix 2003. Recognizing gradual degradation of the Matrix, he is preparing for an updated version, Matrix 2010.

"Differences" is the gap between the desire and the reality. We want to resolve the differences in all the activities of goal setting, problem recognition, designing, problem solving, etc. The author has been constructing his own theoretical framework to handling the difference resolution and has developed his way of diagrammatic representation of such systems and activities. His 14 papers written since 2003 were posted last year in this Web site

We heartily wish the heavenly peace for him and for his family.
TRIZ Paper & Case Study: "The Super Stream Augmented Approach for TRIZ and its Application to Aviation Safety."
Shahid Saleem A. Arshad, Ph.D.(Applied Innovations, Sydney, Australia), May 15, 2009. (Posted: Jun. 16, 2009)
This paper deals with the problems of the speed sensoring system of airplanes. The Author explains the weak points of the current "pitot + static system", whose defects caused several big airplane crash accidents in the history. He suggests 25 concepts for improving and resolving the problem, as a case study for demonstrating his own problem solving method. Two weeks ago, on June 1, an Airbus A330 of Air France plunged into the Atlantic Ocean off Brazil, causing 228 victims. The trouble in the speed sensor 'pitot + static' system is most suspected.as the possible cause of the accident. Just after such an unfortunate accident, the present paper is timely for you to learn. Paper: 37 pages in PDF
TRIZ Forum: "Suggestion of Several Activities To Do for TRIZ in the Current Severe Situations"
Toru Nakagawa (Osaka Gakuin University), Apr. 6, 2009 (Posted: Jun. 16, 2009)
A suggestion originally sent to the Management members of the Japan TRIZ Society. Under the current severe economic situations in Japan, the promotion of methodologies like TRIZ has to face difficulties. In this situation, we should consider some effective/useful activities to be carried our by the Society or by individuals and groups outside the Society.

TRIZCON2009 Presentation: "USIT Case Study: A Mom’s Bicycle for Safely Carrying Two Children"
Hiroshi Sakata (Hitachi Research Lab., Hitachi Ltd.), Tetsuya Sudo (Sekisui House Co.), Keiichi Hasegawa (Bridgestone Co.), Katsura Hino and Akira Kato (Kokuyo Furniture Co.), and Toru Nakagawa (Osaka Gakuin Univ., Japan), Presentation at TRIZCON2009 (The 11th Annual Meeting of the Altshuller Institute for TRIZ Studies), Held on Mar. 16-18, 2009 at Hilton Woodland Hills, CA, USA
This is an extension of our Poster Presentation at our Japan TRIZ Symposium 2008 held last September. In Mar. 2008, the five-membered group worked on this problem in a 2-day USIT Training Seminar instructed by Nakagawa. The results at the seminar and some further refinement afterwards were presented in the Japan TRIZ Symposium
Japan TRIZ Symp. 2008 Presentation: "A Comparison of the Problem Solving and Creativity Potential Shown in Engineers using TRIZ or Lean/ 6 Sigma"
Paul Filmore (University of Plymouth, UK), Oral Presentation at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
The presentation is related to the concepts of 'Highly effective people/engineers'. 'Highly effective engineers' DOES NOT MEAN at all the skillful engineers who can work on a given job with high efficiency without thinking on the problem, on the contrary they mean the people (or engineers) who can break their own mindsets (or Psychological Inertia, in TRIZ terms) flexibly and can creatively solve their problems. The Author learned the concept of 'Highly effective people' from a large number of references, and applied it to obtain the concept of 'Highly effective engineers'. In order to be 'highly effective', what kind of attributes are necessary, what kind of tools and methods are useful to cultivate such attributes and to apply to the real problem situations, the Author is discussing. Many tools in TRIZ can serve to do that, this is one of the main conclusions by the Author. The Author also sent inquiries to several practitioners of Lean Engineering and Six Sigma. And he found that these two methodologies have much room to enhance the methods in this sense.

Japan TRIZ Symp. 2008 Presentation: "How to Use TRIZ Quickly and Effectively in Small Companies -- A Challenge with 4 Findings from Inquiries and with 3 Tools under development -- "
Rikie Ishii (Dunamis Co., Ltd.) [Miyagi TRIZ Study Group], Oral Presentation at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
The Author has organized a TRIZ study group in Sendai City and is actively promoting TRIZ to SMEs. On the basis of Inquiries to over 1000 SMEs in Miyagi Prefecture, the Author's group has developed three handy and useful TRIZ tools. They are: (1) Small 8x8 Contradiction Matrix, with the 8 parameters of the top-most concerns by the SMEs; (2) Worksheets for solving problems concerning to the 8 parameters by guiding to three Inventive Principles from each parameter; and (3) 'Guiding Sheet for New Product Development' with the map of 31 Technological Trends grouped into top 11, middle 11, and bottom 9 trends according to the degree of recognition by the SMEs. The vivid presentation attracted much interest of the Symposium participants.
Japan TRIZ Symp. 2008 Presentation: "Case Study of Introducing and Applying TRIZ to Real Projects for Obtaining Results (= Benefits): Innovating the Product Development Process by use of QFD, TRIZ, and TM together"
Tomohiko Katagiri, Toshiaki Tsuchizawa, and Takeshi Yamanouchi (Koganei Co., Ltd.), Oral Presentation at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
A page of Introduction is written by Nakagawa to the case study of promoting TRIZ in an SME. Koganei Co. is a manufacturer of aero pneumatic equipments, having about 800 employees. Under the severe competitive situations, the Authors were convinced 2 years ago with the needs of innovating their product development process. Thus the Authors started to introduce and apply the set of QFD, TRIZ and TM (Taguchi Method) to their three pilot projects. It is interesting that the company requested only one consultant to guide the team in all the three methods. The users, not the consultant, reported their current activities and achievements vividly. This presentation has won the Second Place of the Presentation Awards according to the votes by Japanese participants. Congratulations!! It is a pity that only 4 slides are translated into English from the 28 slides in Japanese (English translation was supported by J. Shigeta (Hitachi)).
Japan TRIZ Symp. 2008 Presentation: "Why Water Striders can stand and slide on the Water?: A Summer Homework by Son and Father with TRIZ"
Taichiro Miyanishi (2nd Grader, Kenroku Junior High School, Kanazawa /Son), Katsuya Miyanishi ( /Father), Oral Presentation at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
A page of Introduction written by Nakagawa to Miyanishi family's wonderful presentation is posted here in English and in Japanese. The story presented at the Symposium started when a 12 year boy, Taichiro, talked to his father: 'As a summer homework, I want to learn why water striders can stand and slide on the water surface'. Father, Katsuya, thought it could be an interesting work by use of TRIZ thinking, which he learned only half a year ago. With the promise of 'Never to scold', the boy worked on this problem under the Father's guidance. They tried to think of various ideas for standing on the water surface, with reference to various phenomena and effects. Then they checked their ideas at the library, and further built toy models of water striders with the materials available at home. Thus their work is neither a book/internet survey of knowledge, nor observation of the facts, but rather idea generation and verification on the basis of TRIZ thinking. At the end of the Symposium presentation, the boy made a video talk and said 'I enjoyed the work very much and found the TRIZ thinking process interesting'. This presentation won the First Place of the Presentation Award according to the votes by the participants. Congratulations!! This is a monumental work where TRIZ was actively used by a 12 year boy in Japan.

Japan TRIZ Symp.2008 Invited Talk: "TRIZ activity in Corporate R&D Division －Application to system, method, and software technology －"
Yojiro Fukushima (Matsushita Electric Industrial Co., Ltd.), Invited Talk presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
A page of Introduction to Fukushima's Invited Talk is posted both in English and in Japanese. Fukushima has reported his 5-years experiences of applying TRIZ to 150 real projects in the field of IT and software. The TRIZ team gives TRIZ trainings to engineers and also guides/supports engineers in real job projects. In the early stages of planning, problem definition, problem analysis and solution generation, the TRIZ team guides the engineers with TRIZ and some other tools. Such projects have to pass the interim review and final review by the managers and staff of the division; this scheme makes the TRIZ application serious and practical so as to fit with the organization's policies. They have applied TRIZ in a flexible manner adopting it into IT/software fields. The TRIZ team is the first eager readers of Japanese draft version of Umakant Mishra's book "TRIZ Principles for Information Technology". -- Fukushima's presentation is amazing in the new field of TRIZ application, i.e. IT/software.
Japan TRIZ Symp.2008 Keynote: "Directions for Future TRIZ Development and Applications"
Sergei Ikovenko (GEN3 Partners / MIT, USA), Keynote Lecture presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
A page of Introduction to Ikovenko's Keynote is posted both in English and in Japanese. Dr. Ikovenko talks about the overview of TRIZ. In the global scale, TRIZ is still in the Infancy stage in its S-curve. Any product/service in the Infancy stage should find its proper niche for supporting its growth. For TRIZ, the proper niche is the problem solving in technologies, without doubt. Thus we must make TRIZ strong and successful in such an area. For this purpose we need to have the eyes of business managers in technology. The concept of Main Strategic Parameters of Value (MSPV) is useful. There are some more research directions in TRIZ. All together, TRIZ is proceeding towards 'the Science of Innovation'. -- This Keynote gives a clear view of the future of TRIZ.
Japan TRIZ Symp.2008 Keynote: "TRIZ Development at Intel Corporation"
Amir Roggel (Intel, Israel), Keynote Lecture presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
A page of Introduction to Roggel's Keynote is posted both in English and in Japanese. Amir Roggel presented on the promotion of TRIZ in the manufacturing divisions in Intel since around 2002. In the field of manufacturing they have 4 main areas of problem: Ramping new products into high volume manufacturing, Yields, Tool productivity, and Cost and agility. For each area they use proper TRIZ tools. By training engineers and applying TRIZ in real projects, they have made a lot of accomplishments. 3 case studies were reported by colleagues in Intel Malaysia. TRIZ is now the indispensable tool for innovation in Intel, Amir Roggel says.

Forum: Conference Report (21): "Personal Report of ETRIA "TRIZ Future 2008" Conference (Held by European TRIZ Association (ETRIA) on Nov. 5 - 7, 2008, at University of Twente, Enschede, Netherlands)" (Mar. 2, 2009)
Toru Nakagawa (Osaka Gakuin Univ.), Mar. 2, 2009
[Annual TRIZ conference in Europe. 80 participants, 4 keynotes, 3 tutorials, 35 papers, and 5 posters presented. I have closely reviewed all the papers presented at the conference and introduced them here as a personal report for the people who are interested in TRIZ. A number of universities in Europe are carrying out research in TRIZ and thus there seem to arise successful cases of collaboration among universities, industries, and consultancies for introducing and applying TRIZ. Presentations and participations from industries are decreasing, to our pity. There are a number of good presentations especially in the field of furthering TRIZ methodology itself, extending TRIZ for integral use with other relevant methods, penetration of TRIZ in university education, usage of patent databases with the eyes of TRIZ, and non-technology applications of TRIZ, etc. Report in English in HTML
TRIZ/USIT Case Study: "Applying TRIZ/USIT to A Social & Technical Problem: Auto-locking Door System of Apartment Building" (Mar. 2, 2009)
Toru Nakagawa and Arata Fujita (Osaka Gakuin University), Presented at ETRIA "TRIZ Future 2008" Conference, held on November 5-7, 2008 at The University of Twente, Enschede, The Netherlands.
It is a well-known security problem that unauthorized persons can enter the auto-locking entrance door of apartment buildings just by following the preceding residents. Students' discussions were facilitated with TRIZ/USIT to tackle this problem. We found three root causes: the door is closed slowly for safety reasons, residents allow unauthorized persons to enter, and there is no effective social rule to follow when two parties happen to meet at the entrance door. Solution ideas were generated step by step by discussions. A concept of an IT-based logical door system was built to monitor the number of persons who were authorized and also the number who entered. Any group leader has to authenticate himself and to declare the number of accompanied persons whenever the door is open or not. With the new design choice in technology, all the associated psychological and social problems have been solved, hopefully. Paper

Research Note: "Benefits of Drawing Diagrams (1) Experiences from the USIT Case Study: A Mom’s Bicycle for Safely Carrying Two Children" (Feb. 22, 2009)
Toru Nakagawa (Osaka Gakuin Univ.), Feb. 22, 2009
Here I have written down my recent experiences that by drawing a diagram we realized some important findings. In relation to the USIT case study of "A Mom's Bicycle for Safely Carrying Two Children", I have written the following topics: (1) Effect of the height of children's seats: front view figure at the critical timing of falling over. (2) Image of an Ideal system: a figure where no concrete things are drawn. (3) Functional diagram of a mom's bicycle carrying two children: strength of simpler and clearer diagrams. (4) Solution concepts coming from the Functional diagrams. (5) Separating the parent far from the front wheel: Separation of the handlebar shaft and the front fork shaft, carrying two children in front of the parent. These cases are described with the patterns of: Problem situations, Guideline of the method, Former/conventional drawings, New drawings, New findings from the new drawings, and Lessons learnt. These articles also serve to record know-hows of USIT.

Case Study: "USIT Case Study: A Mom’s Bicycle for Safely Carrying Two Children" (Jan. 29, 2009)
[USIT Seminar Group (IDEA Co.)] Tetsuya Sudo (Sekisui House Co.), Hiroshi Sakata (Hitachi Research Laboratory, Hitachi Ltd.), Keiichi Hasegawa (Bridgestone Co.), Katsura Hino and Akira Kato (Kokuyo Furniture Co.), and Toru Nakagawa (Osaka Gakuin Univ.), Presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan
This case study was obtained at the USIT 2-Day Training Seminar held in March 2008 at Tokyo. The Seminar was held by IDEA Co., instructed by Toru Nakagawa under open, multi-company participation. Carrying two young children on a bicycle is currently prohibited by Road Traffic Law in Japan. In response to strong requests from mothers, however, National Police Agency has recently shown an intention of permitting it if some safe bicycles are developed. Hearing the news we tried this case study by using USIT. USIT was applied in the 2-day group practice and the results were further refined later through email discussions. A new conceptual solution was obtained. Nakagawa's introduction to this Poster presentation is added as an excerpt of 'Personal Report of Japan TRIZ Symposium 2008'.
