, Introduction by Toru Nakagawa in Engish
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.
-- Japan TRIZ Symp. 2009 Paper: TRIZ Activities in Korea and Its Success Factors until 2009 (KyeongWon Lee (Korea)); Introduction (Toru Nakagawa) (Jul. 25, 2010)
Slides in English
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 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. 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, the current situations of TRIZ activities in Japan are discussed in response to this paper from 9 + 6 viewpoints

-- Japan TRIZ Symp. 2009 Paper: The Role of TRIZ in the System of Monozukuri Solution Methodss (Osamu Kumasaka, Fumiko Kikuchi, Akio Fukushima (Pioneer Corporation)); Introduction (Toru Nakagawa) (posted: Jul. 11, 2010)
This Poster presentation 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. They list up the engineers' intentions/questions along the phases of the whole Monozukuri process and arrange them in the rows.. The table is as big as (37 questions) x (73 methods/submethods). 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.

In the 5th TRIZ Symposium in Japan, two presentations were given by an Itaian group on the topic of technology forecasting. The Italian group of Gaetano Cascini, Davide Russo, et al. aims at building a repeatable and objective methodology for technology forecasting. Their approach is based on the method called 'Network of Evolution Trends'. In the present paper, Russo et al. try to provide a visual synthesis of a system in all its evolution steps, design variants and future potential configurations. They use a framework named 'Knowledge Mapping' for representing existing knowledge and for identifying what should be done in future.

-- Japan TRIZ Symp. 2009 Paper: Engineers' Understanding of TRIZ As a Consequence of Questionnaire Survey (Yojiro Fukushima, Tsutomu Hata (Panasonic Corp.)); Introduction (Toru Nakagawa) (posted: Jun. 9, 2010)
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.

-- Japan TRIZ Symp. 2009 Paper: The potential of OTSM-TRIZ as a frameworking method for modern regional, integrated energy planning and modeling (Atom Mirakyan, Nikolai Khomenko, Laurent Lelait, Igor Kaikov (Germany)); Introduction (Toru Nakagawa) (posted: Jun. 9, 2010)
The project for a regional (i.e. sub-national) integrated energy planning 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 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.

The present paper serves as an nice introduction to the OTSM-TRIZ, and may be useful for you to learn about it 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).
-- Japan TRIZ Symp. 2009 Keynote Lecture: Use of TRIZ for Prediction of the Future of Technological Systems (Boris Zlotin, Alla Zusman (USA)); Introduction (Toru Nakagawa) (posted: Jun. 9, 2010)
Mr. Boris Zlotin was a follower and coworker of Mr. Altshuller for many years and is a prominent TRIZ Master. He has been working on the present topic of technology prediction for over 3 decades and has developed the Directed Evolution methodology. Here he talks about the problems in technology prediction, the philosophy and methods in the Directed Evolution with some examples. Technology prediction is still, or ever more, important issue in industries and in TRIZ research.

-- Japan TRIZ Symp. 2009 Paper: Practical Use of Scientific Creative Techniques for the Development of Telecommunication Devices (Takahiro Shoji and Yosuke Koga (Panasonic Communications Co.)); Introduction(Toru Nakagawa) (May 30, 2010)
Since 2001, Panasonic Communications Company (PCC) 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. 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 at 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. Slides in PDF

-- TRIZ Forum: Issues for TRIZ: The Journey So Far and the Way Forward for TRIZ (S. Saleem Arshad (Australia)) (posted: May 9, 2010)
A 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. Also posted in Japanese translation by Toru Nakagawa.
-- Japan TRIZ Symp. 2009 Paper: Case Study of Introducing and Applying TRIZ to Real Projects for Obtaining Results (= Profits) (Part 2): Having Used QFD → TRIZ → TM, What are the Results? (Tomohiko Katagiri, Toshiaki Tsuchizawa, and Shuichi Hosaka (Koganei Co.); Introduction(Toru Nakagawa) (posted: May 9, 2010)
The Award-winning Oral presentation at Japan TRIZ Symposium 2009 held last September. The Authors introduced TRIZ together wth QFD and TM and applied them to the real project of developing a new product, i.e. a high-speed response pneumatic air valve. The report describes details of how they introduced and applied these 3 methods to the poject, and of the newly developed product, in its performance, inner structure, cases of applications, etc. The 3 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. Excellent case study paper worthy of learning.

-- Japan TRIZ Symp. 2009 Keynote: TRIZ: Necessary But Not Sufficient: Customers And Theories Of Everything (Darrell Mann, UK); Introduction (Toru Nakagawa) (Apr. 18, 2010)
This is one of the Keynote Lectures pesented at the 5th TRIZ Symposium in Japan held on Spet. 10-12, 2010 in Saitama, Japan. The 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)
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 of TRIZ by Russian spcialists (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. [also posted in Japanese translation by Toru Nakagawa.]

-- Forum: TRIZ Activities in Iran (Mahmoud Karimi (Iran) ) (Feb. 22; Mar. 13, 2010)
A two-page communication outlining how TRIZ has been introduced and penetrated into Iran. 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. Now TRIZ has become a known term among educated people in the country, the Author says. ... We are very much looking forward to the Author's vivid Keynote Lecture
7 photoes provided by Mahmoud Karimi (mostly taken from TV programs) are inserted in this page. (Mar. 13, 2010).

Ikuo Yoshizawa reported the discussion and results obtained at the Business & Management Study Group of Japan TRIZ Society for developing a new business model, in case of a large-screen TV system. Atsuko Ishida (Hitachi), Vitali Altholz (Germany), and Shigeru Kasuya gave presentations in the business applications of TRIZ. Toshio Takahara presented his philosophical view of the whole world on the basis of TRIZ theory and proposed the 'Ideal Way of Life', reagarding it as 'TRIZ Way of Life'. Yukio Matsubara (Niigata Univ.) reviewed the education/apprenticeship system in Japanese history and suggested that the balance of tacit knowledge and explicit knowledge is essential for the healthy growth of a country/society. These presentations demonstrate that TRIZ has been extending its application areas steadily in Japan as well.
