On the 11th Anniversary Day of "TRIZ Home Page in Japan": Toru Nakagawa (Nov. 1, 2009)
This Web site "TRIZ Home Page in Japan" celebrates today its 11th 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 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: "TRIZ Activities in Iran" (Feb. 22; Mar. 13, 2010)
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 consultings and trainings, etc. It is remarkable that they have used mass media effectively; a series of 5 TV programs were made and broadcasted three times already, and interviews and discussions on TRIZ were broadcasted in popular TV talkshows. ... We are very much looking forward to the Author's vivid Keynote Lecture
7 photoes 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 patentablity 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 wih 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 penetraton 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 roler 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-roler. 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 presenration has won the Award by the prticipants 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 inPDF 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
2 Contributed presentations are reviewed. Kimihiko Hasegawa et al. reported their activities at Intellectual Property Creation Study Group, Japan TRIZ Society, and won the Award by participants voting. They analyzed more than 50 patetents with emphasis on the technical contradictions and documented each in the standardized formats. Hideaki Kosha (Fujifilm Co.) et al. also reported on a scheme of analysis of patents/techniques/products from the view point of USIT. This is a work carried out in a voluntary multi-company group, named MPUF USIT/TRIZ Study Group. They intend to build a matrix for indexing from (16 generalized) categories of problem to frequently-used USIT sub-operators, by accumulating the analyses.

3 Contributed presentations are reviewed. Masao Ishihama et al. (Kanagawa Inst. Tech.) reported on a conceptual design of child seats for automobiles; Minami Hamada (1st year MC student) gave a vivid presentation and won the Award by the participants' voting. [Introduction to this paper will be enhanced in a couple of weeks.] Yutaro Ueda et al. (Osaka Gakuin Univ.) reported on 'how to help recall passwords'; Ueda is a 4th year undergraduate student of Nakagawa's Seminar Class. Toru Nakagawa et al. (Osaka Gakuin Univ.) reported on the systematic classification of various known solutions on 'How to prevent cords/cables from getting entangled'. Restricting and then expanding the scope of the system step by step was the key to the systematization.
Forum: Conference Report (22-E): "Personal Report of Japan TRIZ Symposium 2009: Part E. Promotion of TRIZ in Industries" (Dec. 24, 2009)
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/sofware 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 supperted 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 Wookbook for generating ideas of new SW/IT systems.

Toru Nakagawa (Osaka Gakuin Univ.), Dec. 5, 2009
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

Slides in PDF
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.

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
"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

On the basis of 5 patents which the Author's group developed in the period from 1986 to 2005, the Author describes their intentions and thoughts in the R&D field of magnetic recording media, e.g., what they wanted to solve, what kind of technologies they have developed, and what kind of principles they have found and applied, etc. by reviewing their work with the eyes of TRIZ.
-- It was our surprise and pity that Mr. Hiroyuki Suzuki has passed away two weeks ago. This paper, fully described both in Japanese and in English, is the description of his life work viewed with TRIZ and is given to us all as his message. 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.

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.

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'.

Toru Nakagawa, Editor of the "TRIZ Home Page in Japan" (OGU), Poster Presented at ETRIA TRIZ Future 2008 Conference, Held at University of Twente, Enschede, Netherlands, on Nov. 5 - 7, 2008.
On the proposal which I posted here on May 25, 2008, I have newly made several illustrative drawings and presented them as an additional Poster at the ETRIA TFC 2008. Various types of Web sites are considered from 4 different aspects: (1) ways of posting, (2) ways of reading, (3) ways of financial support, and (4) ways of description language. Desirable ways of Public Web sites are shown from these 4 aspects. The vision of the Global Network of Public Web sites having both Outward-Looking and In-ward Looking Windows is illustrated in a slide. The 10 slides well illustrate my original proposal.

The original paper was posted in the TRIZ Journal 6 years ago. K. Ichikawa, a retired engineer from Shin-Dengen Kogyo, Ltd., has voluntarily translated it into Japanese and contributed to this Web site. He actually translated it long ago and read it often during his R&D work in microelectronics for enhancing his own ideas, Ichikawa says.
On the 10th Anniversary Day of "TRIZ Home Page in Japan": Toru Nakagawa (Nov. 1, 2008)
This Web site "TRIZ Home Page in Japan" celebrates today its 10th 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 but a public forum to be composed of the contributions by readers, as you see already. It is intended to publish most pages in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners. On the basis of these experiences, I am now advocating the vision of "A Global TRIZ Community intermediated by Pubic Web Sites built in different TRIZ Communities" for overcoming the language barriers

TRIZ/USIT Forum: "Comments on “Extension of USIT in Japan: A New Paradigm for Creative Problem Solving” Toru Nakagawa" (Sept. 18, 2008)
Ed Sickafus (Ntelleck, LLC, USA), Aug. 23, 2008
Comments by Ed Sickafus, the developer of USIT, on Nakagawa's paper presented at Japan TRIZ Symposium 2008. Sickafus says the transition from TRIZ to SIT to USIT has been guided by simplification, i.e. to reduce structure and to reveal the underlying logic. (See his Keynote Lecture at Japan TRIZ Symposium 2006.) He recognizes that USIT in Japan is 'regressing' to TRIZ in order to address the demands in Japanese industrial environment. He suggests about his experimental projects of 4-membered USIT team to address the bottom line of the company.
TRIZ/USIT Paper: "Extension of USIT in Japan: A New Paradigm for Creative Problem Solving" (Sept. 18, 2008)
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
I have reviewed how USIT was introduced in Japan and has been extended in Japan for these 10 years. (1) I introduced USIT into Japan as an easy-to-learn TRIZ. It forms a basis of my 'Slow-but-Steady Strategy' of introducing TRIZ into Japan. (2) We reorganized all the solution generation methods in TRIZ into the framework of USIT and constructed a system of USIT Operators, having 5 principal methods and 32 sub-methods. This makes USIT a next-generation TRIZ, forming a basis of 'Steady Strategy' of penetrating TRIZ in Japan. (3) Data-flow representation of USIT gave the concept of 'Six Box Scheme', which has been realized as a New Paradigm for Creative Problem Solving. (4) Teaching to university students and training of industrial engineers have been established, and applications to real industrial projects have been carried out in companies. With all these activities, USIT has been contributing to promote TRIZ in a way easy to learn and apply, i.e. a unique feature of the TRIZ community in Japan in comparison to other countries.

Masatoshi Hotta (Sozo Kaihatsu Initiative) and Toru Nakagawa (Osaka Gakuin Univ.), Sept. 7, 2008
The Japanese Translation Project has completed its first draft of the whole volume by the end of July. The Author, on the other hand, has been working for the brushing up of the whole book and sent us the 'final revised version' by early August. Thus we are working further for brushing up our translation manuscripts so as to reflect the Author's final version. We have just prepared a 'Preliminary Sample Edition' for displaying at the 4th TRIZ Symposium in Japan. Some early readers of our manuscripts say "This book explains quite different IT & software techniques from aspects of principles. The descriptions are interesting and useful for software engineers without knowing TRIZ."

TRIZ Forum: From the Editor: Global Network of Public Web Sites in TRIZ:
A Proposal for Building Global TRIZ Community (May 25, 2008)
Toru Nakagawa (OGU), May 24, 2008.
When I rebuilt my page of 'TRIZ Links in the World', I felt much that the language barriers have preventing TRIZ from its better understanding and smoother penetration in the World. As a practical solution to this problem, I am now proposing here "Let's build many Public Web sites in TRIZ in different TRIZ communities in the World and form a Global Network of them". Each Public Web site plays the role of the hub site in TRIZ in the community (i.e., typically a country), and posts various papers/articles contributed by many authors under fair leadership of the Editor(s). It posts papers/articles/news of the outside world after translating them into their own language, and also posts the works and news of their own after translating them into a common language, i.e. English. By forming a global network in Internet of such Public Web sites in different communities, we can build an autonomous and sound TRIZ community in the global scale. This model of Public Web sites was established partly by the TRIZ Journal and in a more typical form by the TRIZ Home Page in Japan. There are also other possible bases of forming such Public Web sites in various countries, as discussed in the text. Full text in English

TRIZ Links: "TRIZ Links" Are Rebuilt (continued): [3] Selected 50 TRIZ Sites in the World ; [4] Extended 120 TRIZ Sites in the World , and [5] Users' 80 TRIZ Presentations in Japan (May 4, 2008)
Compiled by Toru Nakagawa (OGU), May 4, 2008.
The pages of TRIZ Links in the World have be rebuilt completely. After Google searches and tracing various TRIZ link pages, the pages of each site were browsed to learn their nature, contents, and features, even under the limitations of difficulties caused by many different languages. 120 Sites in the World (outside Japan) are listed with brief description for each site.

TRIZ Papers: "Theory of Resolving Differences: A Collection of Papers Written by Toshio Takahara (2003-2007) with Annotated Bibliography" (Mar. 30, 2008)
Toshio Takahara, Dec. 27, 2007
[This page contains all the 14 papers published by Toshio Takahara for these five years and a brief guide to these papers. The 'Difference' stands for the gap between the reality and what we want or what should be. Recognition of such Differences and trials of resolving them are the fundamentals in human activities, the Author understands. Such human activities take various forms and phases, including goal setting, problem recognition, designing, problem solving, etc. The Author is trying to present a unified method of understanding and representing the whole process of Resolving Differences. Behind the Author's unique and hence not-easy-to-adopt terminologies, I realized the clarity in the representations and the significance of the theory last October when I was reviewing his paper

TRIZ Bibliography: List of TRIZ Selected Papers Written by Overseas Authors and Contributed to "TRIZ Home Page in Japan" since 1998 (Feb. 8, 2008)
Toru Nakagawa (Osaka Gakuin Univ.), Feb. 7, 2008
[Selected Papers in TRIZ are listed here; the papers written by Overseas (i.e. non-Japanese) authors and posted (or to be posted) in English and/or in Japanese in this Web site "TRIZ Home Page in Japan" for these 10 years since 1998. All these are excellent papers I have learned much; many of them are openly available in English (or in Japanese) either in this Web site or in their original sources, but still many others are waiting for translation into Japanese and for posting. We recently obtained the approval by TRIZCON and ETRIA of posting original English versions here after several months of the conference even prior to Japanese translation under the permissions by the authors and the conference organizers.]

Forum: Conference Report (19): "Personal Report of ETRIA "TRIZ Future 2007" Conference (Held by European TRIZ Association (ETRIA) on Nov. 6 - 8, 2007, at Frankfurt am Main, Germany)" (Feb. 8, 2008)
Toru Nakagawa (Osaka Gakuin Univ.), Jan. 30, 2008
[Annual TRIZ conference in Europe. 140 participants and 46 papers 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. 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, etc. Report in English in HTML

Kunio Fukatsu (Toshiba Social Automation Systems), Presented at the Third TRIZ Symposium in Japan 2007 Held by 'Japan TRIZ CB' at TOSHIBA Kenshu Center, Yokohama, Japan, on Aug. 30 - Sept. 1, 2007
[Technical knowledge transfer is a current big issue in Japan because many active people in the after-war baby-boom generation are going to retire around the age of 60. The Author has built an intensive intranet Web site of professional knowledge, but has realized its negative effect because such knowledge get obsolete rapidly. Learning TRIZ/USIT recently, he has realized the need to transfer the capability of creative problem solving. He describes a case study carried out in a 2-day USIT Training Seminar.

[In the process of printing the adhesive on a PDB, the adhesive lifted up with the mask sometimes generates bubbles, breading-out, and clogging and they later cause various defects. This problem was analyzed and solved by using various TRIZ tools in a standard way. With the help of Effects knowledge base, the adhesive was improved in its properties on the basis of its microstructure. This paper is useful because of its detailed description of the problem solving process. English page contains Abstract, Nakagawa's introduction
TRIZ Case Study: "Application of Contradiction Table to Computer Architecture －Sub-matrix and Invention Principles for Computer Problems －" (Jan. 7, 2008)

[This case study paper is, as far as I know, the first publication in the world on the application of TRIZ to a real problem in the IT field. The Authors worked on TRIZ for IT around 1999-2000 in the Central Research Lab of Hitachi, to adapt the Matrix parameters and Inventive Principles to the field of computer architecture and to make a reduced Contradiction Matrix for IT of size 14x14. They also applied the Matrix to real problems such as the IT systems for Internet Data Center and succeeded to obtain patents and to implement the ideas in their company's products.
