TRIZ Paper: Fundamental Theory: A Note on a Method and Granularity in the Structure of the World (Toshio Takahara) (Apr. 12, 2015)
An 8-page paper presented at FIT2013 on Sept. 4, 2013. Mr. Takahara's life-work theme is "To understand the world in a consistent manner, to realize the real basis of our human ways of living, and to establish a general and logical methodology for such a study." As the basis of his logic, he builds the concepts of 'existing things' and their relationships, and also the ways of describing the whole world, which contains technologies, institutions, and persons. For such a description, he finds the necessity of 'radical enumerative thinking' (i.e., a clearer extension of 'systematic thinking') and expressions of contradictions (i.e., a clear extension of 'problems'). He also extends the logics of dialectics in a much wider meaning. Then he considers the basis of person's recognitions and actions and derives how the person decides them, with a range of consideration (i.e. granularity) and with a logic for solution (i.e., a thinking method). He discusses further basis of the person, i.e., the person's attitudes. The width and depth, and clarity, of the author's consideration is indeed astonishing.

TRIZ/USIT/CrePS Talk: Methodology of Creative Problem Solving: TRIZ and Its Extension ~ Scientific Methods for Innovation ~ (Toru Nakagawa) (Apr. 12, 2015)
The 57 slides were given in a lecture for 90 minutes at Graduate School of Medical Science, Tottori University, on Jan. 20, 2015. I first describe that the basic Four-Box Scheme of Abstraction which is generally assumed in the current science and technology has a limitation and that many conventional 'Creativity methods' address with different partial aspects without having a sound overall view. As new scientific approaches to inventive thinking, I explain TRIZ first and then USIT. On the basis of them, the Six-Box Scheme was newly formulated as the paradigm for 'General Methodology of Creative Problem Solving' (CrePS). These four stages of development of the methodology of creative problem solving reflect my own understanding for these 18 years. Slides in Japanese and also in English translation .

TRIZ Paper: Social application: Methods and Examples of Applying the Business Management Related Evolution Trend Proposed by Darrell L. Mann – Translating the Evolution Trends from the World of TRIZ into the Daily Business and Management – (Hisataka Izawa, Ikuo Yoshizawa, et al.(Business and Management TRIZ Research Subcommittee, JTS)) (Mar. 27, 2015)
Presented at Japan TRIZ Symposium 2014. The 6-membered B&M Study Group reported last year how to generate 'hit products/services' and found the tool of 'Trends of evolution (TE)' effective. So they tried to make it more useful:
(1) They have made a booklet in Japanese for introducing the Trends of evolution in Darrell Mann's book ("HOSI for B&M").
(2) They have clarified the relationships of TE with several other methods often used in the B&M fields: they include: Nonaka's SECI model, 4 viewpoints in the Balance-score cards, and SWOT.
(3) They made a case study of applying TE: To transfer the technologies of some abandoned business for starting a new business model of servicing the technologies. They have found the examination of 3C (i.e. Customers, Company, Competitors) with respect to the 32 TE very useful.

TRIZ Paper: Social application: Proposal of an Easy Value Evaluation Method by Means of TRIZ - Taking the Proposal for a New Life Style of the Elderly People as an Example - (Part 1) (Kimihiko Hasegawa, et al. (IP Creation Research Subcommittee, JTS)), (Mar. 27, 2015)
Presented at Japan TRIZ Symposium 2014. After having completied a multiple-year project, the 8-membered IP Creation Study Group discussed freely about what they should work on next and decided to work on this topic. They decided 'The aged and their relevant people live a happy life' as the top purpose (or vision) and 'The aged people solve the problems of their own and others' as the target (or goal). In more concrete words, they recognize the problem 'The researchers and engineers around their retirement age want to live a life with some good motivation', and wish to have solutions towards 'For achieving their own visions, the aged people solve their own problems as well as others' problems'. -- This is an important topic for many aged engineers, including many TRIZ practitioners, and for the whole society in Japan.

TRIZ Paper: Industrial application: One Method for Expanding TRIZ Application -- Applying TRIZ to Products that TRIZ can Hardly be Applied to -- (Yoshiharu Isaka (IDEA)) (Mar. 27, 2015)
Presented last September at Japan TRIZ Symposium 2014. In the areas of 'Utility engines' for example, some standard products have been delivered for decades without much change, because of no change in the requirements for basic usage as the power supply in the working machines for agriculture, forestry, etc. Isn't there any room for applying TRIZ? The key is to find the 'sales points' which can convince the target users, i.e., the person in charge of selecting the engine in the working machine manufacturer. Thus one should think of various functions and features as the 'sales points' by using some idea generation methods. This is the 'Theme definition' stage in the problem solving process. Then TRIZ will help to generate some methods for realizing the functions/features. -- This is an unfancy but important proposition.
Presentation slides are posted in HTML in Japanese ; those in English can be referred via a link to the Japan TRIZ Society site (English translation by JTS).
TRIZ Paper: Industrial application: How to Lead Beginners to TRIZ at the Place of Practices (Shigeru Hisanaga (DENSO)) (Mar. 27, 2015)
Presented last September at Japan TRIZ Symposium(see my Personal Report ) and obtained the 'Best presentation for me' Award as a result of participants voting.
DENSO introduced TRIZ since 10 years ago (See ). The in-house TRIZ promoters have guided the projects of applicants, composed mostly by TRIZ-novices. A key to success is realized to adopt the approach and tools which fit well with the needs and intentions of such TRIZ beginners. The author reviewed their 250 projects and characterized them with 3 types of needs (i.e., Want many ideas, Want a good solution, and Want to reconsider from the root) and with 2 types of intentions (i.e., Out of vs. Within the present constraints). For each category of 3x2, the authors examined the TRIZ tools applied, and have summarized the TRIZ tools recommendable in each of the 3x2 categories of beginners' needs and intentions. -- This is a nice presentation with deep insights. The author makes a concluding remark saying: "The success of TRIZ practice depends not only on the technical results but also on the participants' satisfaction. And hence, coaching is more effective than consulting."
Presentation slides are posted in HTML and in PDF , where English translation was recently brushed up by Nakagawa.

Forum: Earthquake Prediction Research: Up-to-Date Report on the Early Detection of Omens of Anomalies in Monitoring Power Plant Equipment (Anomalous phenomena detected just before earthquakes) (Takumi Yoshioka (Mado-Planning), Hiroaki Kawai (Hokkaido Inst. of Tech.)) (Mar. 7; Mar. 9, 2015)
Presented at a symposium of Japan Society of Mechanical Engineers (JSME) in Jun. 2010. The authors developed a software system for monitoring the operation of electric power generators in thermal and nuclear power plants. In such data, they have found effects of earthquakes vividly. The data monitored every minute show the effect of instantaneous jumping of the generator due to the S-wave of an earthquake, and after the quake the data show unstable increase of wattless currents due to some off-alignment of the generator axes. In addition, since 30 minutes before the earthquake there appeared anomalous behavior in the data, just like the generator is roaring. It is not caused by earthquake vibration but by some electromagnetic effect. This paper clearly expresses the possibility of predicting an earthquake. English translation of the full text is not ready.
Forum: Earthquake Prediction Research: Introduction to the Research of Short-term (or Just-before) Prediction of Earthquakes by Use of Electromagnetic Phenomena: Especially Works by Professor Takumi Yoshioka (Hokkaido Univ. of Science) (Editor: Toru Nakagawa) (Mar. 7; Mar. 9; Mar. 27, 2015)
Even though somewhat exceptional for the present site, I am going to start the Forum for introducing researches on earthquake prediction by posting various papers and articles. My intentions are:
(a) Short-term (or just-before) prediction of earthquakes is eagerly desired. Seismological Society of Japan (SSJ) and Japanese government, however, state that short-term prediction of earthquakes is (almost) impossible and make no significant efforts for research in such a direction.
(b) SSJ regards it impossible, because it uses mechanical aspects (e.g., position, displacement, stress, vibration, etc.) as the keys. If so, we should better try to use different types of signals, especially electromagnetic signals, as TRIZ suggests.
(c) The electromagnetic aspects of earthquakes are not yet well known, and researches in such directions are often criticized premature or even as a fake. However, we should make efforts in multiple aspects in parallel, e.g., discoveries of new phenomena, inventions of methods for detecting and observing new phenomena, revealing the mechanisms of the new phenomena, inventions of extracting and utilizing useful information from the new phenomena, etc., so as to stimulate one another.
(d) Last year, Earthquake Prediction Society of Japan (EPSJ) was established for promoting the research of short-term earthquake prediction especially putting stress on electromagnetic aspects.
(e) I recently learned Professor Takumi Yoshioka's work where some electromagnetic signals are detected with online monitoring system of electric power generators. Since I think it hopeful and significant, I wish to support the promotion of its examination and further development.
(f) This Index page of the Forum will show indexes of articles posted in the present site, references, and discussions, etc. [Index to references has been enhanced in the Japanese page. (Mar. 27, 2015)]
TRIZ Paper: Industrial application: Development of a Spinning Top by TRIZ & TM & Simulation -- Challenge at All-Japan Koma Taisen -- (Tomohiko Katagiri (IDEA), SWCN) (Mar. 7, 2015)
This paper was presented last September at Japan TRIZ Symposium (see my Personal Report ) and obtaind the 'Best presentation for me' Award as a result of participants voting.
'All-Japan Manufacturing Industry Koma Taisen (Spintop battles)' was first held in Feb. 2012 and second in Feb. 2013. The koma (or spintop) must be smaller than 20 mm in diameter and be turned by fingers without using any tool. There is no limit in the weight, length, shape, materials, etc. The battle between 2 komas is performed on a slightly concave ring. The koma spinning longer on the ring wins the game, and the koma winning the game twice in a row win the match. See the battles and komas in the Koma Taisen site
The presentation slides explain the processes of considering various contradictions in the design and examining different design prototypes by use of Taguchi method and simulations. The SWCN's koma (named 'cat's punch') was extraordinary in its shape; just after turning, the koma opens its 3 arms for hitting out the competitor, and it won the second place at the Second All-Japan Koma Taisen.

Paper: Social revolutions: Generalized structure of social revolutions (Tetsutarou Yasuhira (Advanced Institute of Science and Technology, Japan)) (Feb. 10, 2015)
Originally published in Journal of Japan Society of Information and Knowledge in 2010, and reposted here under the permission of JSIK. The author describes the processes of big social changes, or revolutions, in a general and conceptual way. Since TRIZ tries to identify and solve contradictions to proceed for ideality, we know that we can apply TRIZ not only to technological problems but also non-technological, human, and social problems. The abstract and the figure in English show the essence of the present paper, I hope. The full paper and author's profile are posted in the Japanese page.
TRIZ Paper: TRIZ marketing for the Ubiquitous concept ～ So that anyone uses TRIZ anywhere anytime ～ (Shigeru Kasuya (Proengineer-institute)) (Feb. 10, 2015)
Presented last Septmber at 10th Japan TRIZ Symposium. Responding to the TRIZ users' apparent/hidden needs, the author tries to make TRIZ inexpensive and ubiquitous, with the slogan of "Anyone can use TRIZ anywhere anytime." He presents 10 examples of such solutions: Smart phone version of 40 Inventive principles (1 screen/principle); 40 Inventive principles adapted for the IT/software field; understanding various other methods in relation to TRIZ (e.g., Checklist method by Osborne, NM method (by Masakazu Nakayama), Wai-gaya meeting at Honda, Goal deployment, QC story approach, etc.).

Paper: Creativity Tool and methods: Introduction to Visual Thinking Software 'Fuda-Yose Tool' and Its Web site 'Thinking School I' (Akihiro Katahira) (Jan. 18, 2015)
The author developed a handy software tool for drawing and handling labels smoothly on Excel sheets for supporting 'Visual Thinking'. Information in Excel cells can be converted with a click into labels, and such labels, connecting lines, and enclosures may be moved around smoothly on the sheet. The use of the software stimulates users' thoughts in idea generation, document composition, discussions in a group, etc. The author has also built a Web site describing various methods for generating thoughts in a systematic, yet easy to understand manner. He puts emphasis on his 'Visual Thinking' supported by his 'Fuda-Yose' software tool. In Japanese the software tool and the Web site are fully described, while in English only the tool is introduced by Nakagawa's translation.

TRIZ Paper: Finding the needs of customer by the SN Matrix and TRIZ process -- The functional approach for connecting methods and 7 solutions -- (Takashi Ogata, Kazuhiro Fujikawa, Hiroyuki Tsuchiya (OLYMPUS Corp.)) (Jan. 18, 2015)
Presented at 10th Japan TRIZ Symposium 2014 and won the 'Best Presentation for Me' Awards by the participants voting. The authors pursue for the methods of linking their technological seeds (S) with their customers needs (N); they want to provide new products/services of attractive quality and to reveal some hidden needs of customers. For such a purpose they have developed a scheme of describing their aims and means consistently in terms of 'functionality'. For each of the functions, the authors clarify their goal/current levels of realizing the function, competitors' technology (contents and their levels), customers' requirements, and priority, and write them down in a tabular form named as 'SN Matrix'. The SN Matrix is consistently applicable in their 7 categories of problem solving processes (or 'solutions'). -- This is an excellent presentation having experiences of real applications and theoretical framework together. Extended Abstract in HTML and in PDF and Presentation slides in HTML images. The Japanese page is composed in a similar way.
From the Editor: Message for the New Year 2015 (Toru Nakagawa (OGU)) (Jan. 8, 2015)
Greetings from Japan for a Happy New Year 2015!! Wish the year be healthy, happy, and successful for you all and peaceful in the World. I am posting the New Year card in Japanese which I sent to many Japanese friends whom I got acquainted before my TRIZ days. I am much concerned about the current situations of Japanese society. Prime Minister Shinzo Abe is driving Japan in the wrong direction. Democracy in Japan is not working well unfortunately. There are many big and complex issues to be addressed in relation to lives of people. -- In such a situation, I should do my best what I can; i.e., to establish the General methodology of creative problem solving (CrePS) and to spread it widely. I have written down several tasks and plans for the new year 2015. I wish to work for them in collaboration you. Best wishes!

TRIZ Forum: Letters from Readers: Introduction to A New Publication: "TRIZ 40 Principles" by Yoshinori Takagi (Yoshinori Takagi; Toru Nakagawa) (Jan. 8, 2015)
The present page introduces to an excellent new publication in Japanese, "TRIZ 40 Principles" by Yoshinori Takagi, published by Discover 21, Inc., Tokyo, on Aug. 30, 2014. The book is very well organized in the contents, in the grouping of Principles, in the descriptions of individual Principles, and in illustrating application examples of the Principle, etc. It is quite reasonable that the book has been one of the best sellers in the Engineering/Patents & Invention genre in Amazon.co.jp. Congratulations!! Unfortunately, however, in the belt and in the Preface of the book, the descriptions look too much journalistic/sensational, used to be typical in late 1990s in Japan, and contain several misleading catch copies in relation to the TRIZ history in the former USSR. Nakagawa sent a comment to Mr. Takagi on such misleading catch copies for the purpose of preventing them from being spread to readers new to TRIZ. (Full description in Japanese, but shorter in English.)
TRIZ Paper: SUGOROKU of TRIZ Inventive Principles ～ 40 Principle Symbols Arranged on 9 Windows ～ (Yoshinori Takagi) (Jan. 8, 2015)
This paper was presented at 10th TRIZ Symposium in Japan, Sept. 11-12, 2014. Extending the work of hand-script symbols of the 40 Inventive Principles, the Author is reporting the idea of classifying the 40 principles into 9 groups for easier teaching. The principles are classified into 4-membered groups from the top, with a minor adjustment to make the 8th and 9th groups into 6-membered groups. He has given names to the nine groups, then arranged them in the 9 windows (3x3), and made the path of going through them in a way like a sugoroku game. He explains how to teach and utilize the Principles and their symbols, by using the 'Making harmless' group of Principles 21 to 24. English translation of slides was supported by Toru Nakagawa. The present site posts the Extended Abstracts , and slides in HTML and in PDF .

TRIZ Paper: Symbolize TRIZ 40 principles (Yoshinori Takagi (Sony)) (Jan. 8, 2015)
Presented at 8th Japan TRIZ Symposium 2012. TRIZ 40 Principles are very powerful tools but 40 are too many to remember. Thus the Author devised hand-script symbols of the principles by arranging the style of the principle number to represent the meaning of the principle. In this manner, the principles and their numbers have been made easier to remember in pairs. By using them repeatedly, one can remember the principles by heart and can use, say, the Contradiction Matrix fluently and take notes of principles coming out in mind while reading technical documents, he says. The present site posts the Author's Extended Abstract and slides in HTML in Japanese, while it has a link to the slides in English PDF at the Japan TRIZ Society site.

Innovation Paper: Rethinking Innovation (The Blue LED case and Paradigm Disruptive Innovation) (Eiichi Yamaguchi (Doshisha Univ.; currently: Kyoto Univ.) (Dec. 10, 2014)
Professor Yamaguchi is the author of "FUKUSHIMA Report', posted here in Sept. 2013 . In October this year, I met him for the first time at ICSTI2014 and impressed with his presentation on innovation. So I read his book "Innovation -- Paradigm Disruptions and Fields of Resonance" (NTT Press, 2006) (in Japanese). He investigated the cases of innovation of transistors and blue LEDs and discussed about the structure of innovations. He argues that the case of LED innovation (and many others) is not the type of Christensen's Disruptive Innovation (of decreasing the performance for some other needs/purposes) but the type of Paradigm-Disruptive Innovation (by disrupting/changing the basic/physical paradigm). He discusses how such paradigm change can be achieved, and why big excellent companies often fail in front of such a paradigm change. On my request he kindly sent me his two papers, which are summaries of his book and were published in Japanese (2004) and in English (2006), and permits me to repost them here publicly.
Tonight (Dec. 10, 2014), three Japanese researchers, Professor Isamu Akasaki, Professor Hiroshi Amano, and Professor Shuji Nakamura are to be jointly awarded the Nobel Prize in Physics 2014 "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources". Congratulations! -- I am very happy to repost Professor Yamaguchi's paper here now, with which we can learn how the Nobel Prize awarded LED innovation was achieved and how we would be able to contribute to future innovations.
TRIZ Forum: Conference Report (30) Personal Report of The 10th TRIZ Symposium in Japan, 2014 （Sept. 11-12, 2014, Tokyo）(Toru Nakagawa (OGU)) (Nov. 27, 2014)
The 10th Japan TRIZ Symposium 2014 was held last September by Japan TRIZ Society. The Symposium for 2 days had 135 participants in total (mostly from industries, and some from academia; 36% participated for the first time; from overseas: 2 invited speakers + about 3(?) participants). Invited talks: Keynote lecture by Anatoly Guin, Special Invited lecture by Shin Taguchi, and Tutorial 1. 27 Contributed presentation (including 22 oral + 5 poster presentations (including 1 from overseas)). The Symposium was organized well, obtained high-level presentations, and had increased number of participants, all showing its big success. The aspect that the contributions from overseas to presentations and participations are quite small need to be improved.
For all the presentations, slides are projected in Japanese and in English in parallel. Japan TRIZ Society has recently posted the invited talks and 5 award-winning contributed presentations openly in their Official Web site, while all other contributed presntations in the Members-only pages.
For applying TRIZ, a number of industries have suuccessfully adapted TRIZ tools and processes so as to correspond the differences in purposes, characteristics, and fields of the problems and to match with the levels, orientations, available time, etc. of users. They also request external consultants to guide them using TRIZ tools suitable for and effective in their needs and situations. Similarly for the integral use of other methods (e.g., QFD, Taguchi method, Kepner-Tregoe method, etc.), they start using them by smoothly linking the essential parts of them. Apparently TRIZ people in Japan are increasingly interested in applying TRIZ to the problems in software, non-technology, and social fields. There are also many trials to make the TRIZ tools easy to understand and effective to use. In these many aspects, we can say that Japanese industries are advancing TRIZ usage and achieving results in the real jobs.
A vivid report was givien by a national college of technology, but almost no report on TRIZ educaion in unversities.
Even though "innovation" is the top-level fashonable keyword in Japan and in the world, we still have not succeeded in introducing TRIZ into national policy and projects, industrial top managements, universities and academia, etc. This is the most important problem for us TRIZ community.

-- CrePS/TRIZ/USIT Paper: General Methodology of Creative Problem Solving & Task Achieving (CrePS): Reorganizing Various Application Cases and Their Methods in the ‘Six-Box Scheme’ (Toru Nakagawa) (Nov. 7, 2014)
Three papers of the same title but with some adjustments were presented at three conferences: i.e., (A) Japan TRIZ Society, 10th TRIZ Symposium in Japan (Sept. 11-12, 2014, at Waseda Univ., Tokyo); (B) Japan Creativity Society, 36th Annual Conference (Oct. 25-26, 2014, SANNO Institute of Management, Tokyo); (C) European TRIZ Association (ETRIA), 14th World TRIZ Future Conference 2014 (Oct. 29-31, 2014, EPFL, Lausanne, Switzerland). My main message is: "We can establish the General methodology CrePS on the basis of TRIZ/USIT research by reorganizing a wide variety of problem solving methods in the 'Six-Box Scheme'". The on-going research activities for developing CrePS are: (1) To make course materials of CrePS case studies. (We should just use case studies already published.) (2) To understand different methods (including TRIZ) and to describe them in the framework of CrePS. (3) To relate CrePS to various activities in the 'Real world'. (4) To categorize various purposes of CrePS application, and to recommend concise CrePS processes for each category. (5) To proliferate the vision of CrePS. -- I wish you to share this vision and collaborate together!
In the English page, the slides presented at ETRIA TFC are posted but not the paper yet until ETRIA's public posting in Elsevier Procedia. In the Japanese page, the slides (for ETRIA TFC in Japanese translation ) and the paper (for JCS ) are posted. In addition, the following PDF files are also posted: Paper (for JCS ), Slides (for Japan TRIZ Sympo , for JCS , for ETRIA TFC ).
-- Editorial: On the 16th Anniversary of "TRIZ Home Page in Japan": (Toru Nakagawa) (Nov. 7, 2014)
This Web site "TRIZ Home Page in Japan" celebrates its 16th Anniversary on Nov. 1 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. I envisage that Pubic Web Sites built in different TRIZ Communities will form A Global TRIZ Community with much reduced language barriers . Since two years ago I have been proposing to establish a General methodology for creative problem solving & task achieving by integrating various creativity methods including TRIZ/USIT . I am going to widen the scope of this Web site gradually in future. The number of visits since November 2005 is (on Nov. 4) 212,212 (increasing by about 14,000 for the last 1 year) to the top page in Japanese and 36,711 (increasing by about 3,300) to that in English. Four Entrance Pages have recently been installed for your easy access to articles. Readers' contributions either in English or in Japanese are heartily welcome.
