|Announcement: Publication Announcement of the Japanese Edition: Darrell Mann's "Matrix 2010: Re-updating the TRIZ Contradiction Matrix" (Toru Nakagawa (OGU and CrePS Institute)) (Apr. 17, 2014)
As the second volume of "TRIZ Practices and Benefits" series, we have just publised the Japanese Edition of Darrell Mann's "Matrix 2010" (Japanese translator: T. Nakagawa).
'Contradiction Matrix' is known as a typical method in TRIZ, but in fact it had a peculiar history of development and evaluation. The Contradiction Matrix published today in most (i.e., except Mann's) TRIZ textbooks is the one of size 39×39. It was originally developed by G. Altshuller with tremendous paper-and-pencil efforts by the beginning of 1970s. Engineers at that time, and nowadays as well, were much attracted to it with the great vision and results. However, Altshuller himself evaluated its usefullness below his expectation, and hence he omitted this method from ARIZ in mid 70s and did not recommend it any longer to his students. When TRIZ was introduced to the Western world in 90s, basic and earlier knowledge of TRIZ was mostly brought in, and Contradiction Matrix became popular. It has been used in the old form, because updating it would need a huge work.
Darrell Mann et al started the big project of updating Contradiction Matrix in 2000; they analyzed all the US patents granted since 1985 with full usage of modern IT tools. Their Matrix 2003 is of size 48×48, while Matrix 2010, size 50×50. Categorization into parameters and the suggestions of applicable Principles have become easier to understand and apply. I believe that we should use the updated Matrix instead of the original/old one, for appreciating and furthering the vision and philosophy of our TRIZ Father.

-- TRIZ Paper: TRIZ Propagation: Effective strategy to introduce and propagate TRIZ into companies based on the bad and good experiences in Korea (Kyeongwon Lee (Korea & France)），Bibliography and Japanese translation (Toru Nakagawa (OGU)） (Apr. 2; Apr. 9, 2014)
Paper presented last October at ETRIA TFC2013. Korea is the country most successful in introducing, propagating and applying TRIZ in industries, among the countries in the world. In the initial stage of introducing TRIZ in Korea (ca. 1996 - 2005), TRIZ was not accepted widely because of various barriers and bad experiences, the Author says. The situation was changed by the success of practical industrial examples developed in Samsung by Russian TRIZ experts employed at TRIZ promotion department. Executives of Samsung recognized the success, and promoted to develop education and training programs and expand the application of TRIZ to real projects. Such TRIZ activities were expanded to other big industries in Korea, and were carried out with much enthusiasm as a big movement in Korean industries, he says. On the basis of 'bad' and 'good' experiences, the author suggests 'Effective strategies' for introducing and propagating TRIZ in industries. PDF files of the paper and the slides in English, and the Japanese translation of the paper . [Note (TN, Apr. 9, 2014): According to ETRIA's request, I have temporarily closed the links to the original English paper and English slides, until they are posted openly by a publisher's site. My introduction in this English page and the Japanese translation version remain being posted. I am going to post several other TFC papers in a similar way.]
I collected the papers concerning to TRIZ activities in Korea as a bibliography. There are about 40 papers (including original papers/presentations and my own introductions to them in my Personal Reports of conferences), having direct links mostly in this Web site and some in other official sites.
|-- TRIZ Forum: Southbeach Forum: Brief Guide of How To Use the Southbeach Modeller (in the Editor Mode) (Toru Nakagawa (OGU)) (Apr. 2, 2014) (in Japanese Jun. 9, 2013)
The Southbeach Modeller is a very sophisticated and excellently designed software tool. It has so many functions, features, and options, and yet is shown on the window in a very compact way. It has a rich library of white papers, specifications, demo videos, sample outputs, and examples made by developers and users. The usage of the software is mostly intuitive. However, its users meet some difficulty for starting up. Thus I wrote this Guide a year ago, for assisting the beginners to get started in using the Southbeach Modeller in the Editor Mode (i.e., for building the models). And today I am posting it in English translation.

-- TRIZ Education Case study: "12 Years of Lecture and Seminar Classes on 'Methods of Creative Problem Solving' " (Toru Nakagawa (OGU)) (Mar. 16, 2014)
A poster presented at the 2nd Conference of Innovation Education Society, held on Mar. 10-11, 2014 at Keio University, Yokohama. The 'Innovation Education Society' of Japan was established last year. Its core groups are 3 prestigious universities, i.e., 'i.school' of the University of Tokyo, SDM (System Design Management Course) of Keio University Graduate School, and QREC (Robert T. Huang Entrepreneurship Center) of Kyushu University. The society is going to develop and promote the methods and systems for educating the motivation, mind sets, skills and techniques, leadership etc. necessary for achieving innovation, towards undergraduate and graduate students (and young engineers and business people). The conference this year obtained over 200 participants from universities and industries, and over 40 case studies presented with posters in parallel. Most people are interested in how to motivate and acquire skills in social and business oriented areas. I presented my 12 years of experiences of education at OGU in the field of (technical) creative problem solving, which forms the basis of 'Innovation' in most cases, I believe. 8 slides in Japanese.

|-- Announcement: Publication Announcement of the Revised Japanese Edition: Darrell Mann's "Hands-On Systematic Innovation with Matrix 2010" (Toru Nakagawa (OGU and CrePS Institute)) (Feb. 16; Mar. 10; Apr. 17, 2014)
The book series "TRIZ Practices and Benefits" in Japanese has been restarted in publication by 'CrePS Institute'. The original Vol. 1 of the series was our Japanese edition of Darrell Mann's excellent textbook "Hands-On Systematic Innovation" (HOSI) . It is now replaced with the revised version Vol. 1A "HOSI with Matrix 2010" in short. Using the latest Matrix in the textbook HOSI is quite natural for the author and for us readers. Thus, under the author's approval, I have revised the text at the minimum level while including Matrix 2010 in its full extent. Darrell Mann's new preface is shown in this English page. In the Japanese page, detailed information, e.g. Nakagawa's preface, table of contents, and a large number of "Notes for the Revised Japanese Edition" (Toru Nakagawa) in relation to Chapter 10. Technical Contradiction and Contradiction Matrix 2010. The new Japanese edition is now available through Print on Demand and digital downloading at DLmarket site. (Mar. 10, 2014).

|-- Editorial: Message: Start of CrePS Institute and publication of "TRIZ Practices and Benefits" book series (Toru Nakagawa (OGU and CrePS Institute)) (Feb. 16, 2014)
For starting the publication of TRIZ book series, it has become necessary for me to take the official business responsibility as a publisher. So I have just started 'CrePS Institute', a sole proprietorship, and have become its Director. Its activities are to be: Research, education, and proliferation activities of creative problem solving methods (e.g., TRIZ, USIT, CrePS, etc.).
-- TRIZ Paper: Innovation: Thinking Differently to Create Value (S. Saleem Arshad (Australia)) (Jan. 26, 2014)
Dr. Arshad has raised a question about the real contents of the fashionable keyword "Innovation". Behind the current global trend of pursuing "Innovation", something different and more fundamental has been lost, he discusses. He shows a two-dimensional space for categorizing various studies and methods of how to achieve "Innovation" (including improvement and problem solving, etc.), where one axis is along the outcome-based vs. process-based approaches and the other axis along the conceptual knowledge vs. practical knowledge. He argues the needs of works with more process-based approaches and of more practical knowledge. -- In recent years the global TRIZ community have made various activities and progresses in TRIZ, and yet I feel we are losing the ground of TRIZ in some aspects. We need to reconsider our standing points and our directions to go. I wish you to contribute your thoughts to open discussions. PDF .
-- TRIZ Paper: Case study: In-house Promotion of TRIZ Use through Practice (Shigeru Hisanaga, Hiroshi Takenaka (DENSO Corp.)) (Jan. 26, 2014)
This paper was presented last September at the Japan TRIZ Symposium 2013 and received the 'Award of Best Presentation for You' according to the participants voting. DENSO Corporation is a big company in the TOYOTA group. This paper reports that DENSO has introduced and applied TRIZ for these 10 years to about 250 projects. They suggested in conclusion: "There can be different ways for promoting TRIZ in an industry. Promotion through 'Real practices' is one of them, i.e., To apply TRIZ anyway to real job tasks, to have many experiences of small successes and failures, and through such lessons, to find new approaches and tools suitable and useful for ourselves."

-- TRIZ Paper: Case study: 7 Solutions to extend the application of TRIZ - Including the prevention of design risk - (Takashi Ogata, Kazuhiro Fujikawa (OLYMPUS Corp.)) (Jan. 26, 2014)
This paper was presented last September at the Japan TRIZ Symposium 2013 and received the 'Award of Best Presentation for You' according to the participants voting. Mr. Ogata has won the Awards 3 times running since 2011!! In Olympus Corp., the authors have introduced the scientific methods like QFD, TRIZ, and Taguchi Method since 2009. From the start they tried to introduce the methods on the standpoints of engineers, so as to be quick and effective in their busy schedule, and to select and apply suitable tools depending on their purposes. At the presentation this year, they have shown 7 sequences of applying selected tools (elements in QFD, TRIZ, and TM) for different purposes. They call them '7 Solutions'. (-- In Japanese IT jargon, 'Solution' means a software system or method /process to be applied to some big user's jobs.) They describe the processes and methods in each 'Solution' and explain the basic concepts underpinning the seven Solutions. I evaluate this paper unique and valuable from the international viewpoints and hope it useful and stimulative for many readers in Japan and in the world. PDF
-- Editorial: Message for the New Year 2014 (Toru Nakagawa) (Jan. 11, 2014) (Jan. 26, 2014)
Greetings from Japan! I posted this New Year message in Japanese on Jan. 11, but in English only now, near the end of January. You see my New Year card (in Japanese) and three enlarged photoes: aurora in Finland and opera at the Arena of Verona, Italy. The society in Japan (as well as in the world) is facing with many complex and serious problems. For addressing to such complex problems, we need to build effective methodologies of problem solving and apply them to the real practices in various places. The demands in society are so huge but our power for building tools is so limited. I would like to make our best efforts step by step in cooperation with you.
-- TRIZ Paper : Scheme of 'New Product and Service' System Creation Using TRIZ -- Search for a Creating Method of "New Product and Service" System by Analyzing "Hot Sellers and Services" Using TRIZ -- (Ikuo Yoshizawa (SANNO Inst. of Management), Hisataka Izawa (Sony), Fumiko Kikuchi (Pioneer), Yasuo Moriya (Fujitsu Advanced Technologies), Osamu Ikeda (Nikon Imaging System) (Dec. 23, 2013)
This is an excellent report of the work conducted by a study group of JTS for these 4 years and presented in Japan TRIZ Symposium 2013. In the field of business and management application of TRIZ, the authors have chosen the success of Yamato Transport Co.'s "TA-Q-BIN" (Door to Door parcel Delivery Service) business as the model of their case study. The authors studied to identify contradictions in the historical situations around the business; they also evaluated the present stage of evolution in several aspects of the business and estimated the next future stage of evolution. The case is of special interest as a unique business developed for these 40 years in Japan. The presentation has 50 slides with rich contents (PDF ) (English translation of slides by the Japan TRIZ Society).
-- TRIZ Forum: Letters from Readers (Discussions) : Research focus is on problem finding and solution execution rather than problem solving (Darrell Mann (UK))/ Thinking methods for problem solving are the basis we should establish now (Toru Nakagawa) (Nov. 17; Dec. 23, 2013) (Dec. 23, 2013)
Email discussions by Darrell Mann and myself were posted on Nov. 17 in English, and reposted here in a separate page in Japanese translation. Mann raised an important issue on our research focus in relation to my proposal of 'General Methodology of Creative Problem-Solving/Task-Achieving' (CrePS); he says: "Difficulties in the innovation are to identify a 'right' problem and to execute the ideas generated. Problem solving itself is rather easy." I responded, from my viewpoint of the Six-box Scheme of CrePS, saying: "The two difficulties raised by Darrell need to be considered in the 'Real World'. Whereas the main part of problem solving should be carried out in the 'Thinking World'. The methodologies of problem solving, including TRIZ, have not found a good framework (i.e., scheme or paradigm) and hence have been confusing. Introducing the framework of the Six-box Scheme and establishing CrePS, the problem solving methodology in the 'Thinking World' will become clear and systematic. It will certainly give the basis for innovations and contribute to much wider areas of application." .

The author has shown the scheme of trends of evolution of (technical) systems in a diagram named 'Universal Trends of Evolution (USE)'. He proposes to collect various information concerning to the target system and to map them in this diagram. Using intelligent internet search, artificial intelligence software of the USE diagram, and 'scientist-robots' together, a 'Discovery machine' can be built in future, he says. The USE diagram apparently well represents the hierarchical nature of system evolution, I feel. Slides in PDF .
|-- TRIZ Paper: Now, Once again, 'There is no TRIZ that doesn't work' － As a core technology for solution － (Hajime Kasai (IDEA)) (Dec. 9, 2013)
This paper was presented at Japan TRIZ Symposium 2013 and has received the 'Best presentation for you' Award by the participants' voting. "There is no TRIZ that doesn't work" is the motto of IDEA Inc., which started as a consulting firm specialized in TRIZ in 2003, as presented by Hiroto Hayashi . Since then IDEA has been promoting TRIZ actively, and the present author Mr. Hajime Kasai alone has experienced 119 cases of applying TRIZ to real projects. The author is disclosing his application methods after classifying them according to the six types of problems, i.e., Problem solving, Performance improvement, New method identification, Cost reduction, Reduction in size and weight, and Product planning. The methodology uses various selected tools in TRIZ, and depending on the requirements uses QFD at the preceding stage and TM at the subsequent stage. The author has set up customized full processes by selecting suitable tools for the 6 types and calls them as 'solutions'. -- I noticed that this presentation coincides with my proposal of CrePS in several points.

In the official home page of Japan TRIZ Society, you can read the slides of invited talks and 5 commended presentations both in English and in Japanese . I am posting my Personal Report (of 3 pages in Japanese), introducing selected 12 presentations briefly. (Though I was not involved in the Symposium organization this year,) the Symposium was prepared and operated well, having mostly good quality presentations, and was a success (in the domestic sense). Two important issues of the present Symposium were the shrinkage in the international nature and the reducing in the presentations by Japanese major companies.

-- Creativity lecture: Creative Company and Methods (Makoto Takahashi (SOKEN Research Institute)) (Nov. 17; Nov. 18, 2013)
Special Invited Talk presented at 4th Global TRIZ Conference in Korea (GTC2013), held last July in Seoul.
Dr. Takahashi has been one of the top leaders of the creativity movements in Japan since 1960s. In 1974 he started a creativity consulting firm 'SOKEN Res. Inst.' and has guided a large number of companies and municipal offices, etc. He has authored or edited about 70 books, including "The Bible of Creativity" (in Japanese) published in 2002.
In the present lecture he talks about the history and thoughts of his and Japanese creativity movements by using a variety of real cases. For instance, in the case of the reforming of Asahiyama Zoo in Asahikawa city, Hokkaido, a big success was achieved by constructing a concept of 'Making it possible to see the characteristic natural behaviors of (rather familiar) wild animals closely and naturally'. He talks about how the creative company should be managed and also suggests that various creativity methods should be used more effectively in TRIZ. -- In the Editor's Note at the end of this page, I am discussing on the overview of creativity methods, in response to Dr. Takahashi's overview.
Editorial: On the 15th Anniversary of "TRIZ Home Page in Japan" (Toru Nakagawa (OGU)) (Nov. 17, 2013)
This Web site "TRIZ Home Page in Japan" celebrates its 15th 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 last year 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. 6) 197,984 (increasing by about 18,000 for the last 1 year) to the top page in Japanese and 33,497 (increasing by about 3,400) to that in English. Readers' contributions either in English or in Japanese are heartily welcome.
-- CrePS Documents: General methodology for creative problem solving and task achieving (CrePS) : Systematized Documents (Technological Areas) (Toru Nakagawa (OGU)) (Oct. 20, 2013)
This page intends to be the document of systematized description of the 'General methodology for creative problem solving and task achieving (CrePS)' . It is described in a hierarchical tabular format and in an accumulative manner. The full contents of the CrePS methodology will be shown in a way easy to view and read in tables arranged in a hierarchical system. I wish that the descriptions are carried out by a (large) number of contributing authors with many (countless) times of revisions. Starting the first step is most useful to show the direction, I suppose. Thus I posted the present page in Japanese (outline and further descriptions) and in English (outline only, at moment).

They are full papers describing on the general methodology CrePS with the focus on its vision. The Japanese paper is addressed to non-TRIZ audience with an emphasis on the needs of unifying various creative problem solving methods into a general methodology, while the English paper to TRIZ specialists/practitioners putting stress on the significance of establishing a general methodology of creative problem solving across the border of TRIZ.
They assert that by introducing the 'Six-Box Scheme' as a new paradigm, various approaches of creative problem solving, including TRIZ, can be integrated smoothly into a unified system, i.e., a general methodology, of rich techniques of creative problem solving. The methodology consists of three major parts: (a) Initial part (from Box-1 to Box-2): in the 'Real World' we should grasp a problem and make a clear focus on it. (b) Main part (from Box-2 through Box-5): in the 'Thinking World' we should analyze the problem, understand the present system, make images of ideal systems, generate ideas for new systems, and then build them up into conceptual solutions. (c) Succeeding part (from Box-5 to Box-6): in the 'Real World', we should implement the conceptual solutions into specific real solutions in our new products/services. The papers describe the contents of them in tables.
We, together with you, can establish such a general methodology, and by handing it out to many different people in the country and in the world, it can be applied to various problems in different fields in the whole country and in the whole world to obtain creative and peaceful solutions. -- This is the vision and message of these papers.

-- Southbeach Forum: Trial Use Report (1): Report of 3-month trial use of Southbeach Modeller (Morimasa Okada （York Mart Co.)) (Oct. 3, 2013)
The first report of 3-month free trial use of the Southbeach Modeller in the CrePS-SB Project. He reports:
"Purpose: To make models of the functions of a supermarket for the purpose of visualizing how to reform the conceptual design of deploying supermarkets and how to develop new business models. Impressions: Even though the problem situations are vague and complex, the software tool supports us to build the model of our vision intuitively and smoothly. ... Examples: Three models are disclosed here. (1) Conceptual design of a smaller-scale supermarket to be deployed in downtowns and residence areas. (2) Model of retail functional units, (3) Model of roles of Visionary, Knowledgeable, and Implementing persons in the case of problem solving in retail functions. ... I wish to accelerate the evolution of supermarkets by using this Southbeach Modeller. With a Japanese edition of the software tool, it would be much easier to use."
