-- 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.

Editorial:  'General Index' page has been reorganized and divided into 4 pages (Toru Nakagawa)   (Sept. 25, 2014)  (Oct. 17, 2014)

The General Index provides a large number of categorization tables which contain all the articles posted in the present site for these 16 years since its start.  Each article is shown by the title, the authors, and the date of posting/update, and has links accessible with one clik to its English page as well as its Japanee page.  With the accumulation of articles, the General Index page has become so heavy that I have divided it into four pages.  They are:

General Index  (A) Parent page and Editorial: Guide to the preent site, Index of 'From the Editor' pages 
General Index  (B) References:  References, Links, News and activities, Software tools:  
General Index  (C) Papers:  Papers, Case studies, Technical reports, Introductory articles, Lecture materials, Documents of methodologies:  
General Index  (D) Forum:  Reports of conferences; Book reviews; Communications, discussions, questions, opinions, feedbacks, etc.; Collabo pages:  

Editorial:   Four 'Entrance Pages' to the present site have been built to make this site friendly to different types of readers (Toru Nakagawa)  (Sept. 7; Sept. 25; Oct. 17, 2014)

The top page of this site has been renewed and four 'Entrance Pages' have been introduced. The table cells of 4 different colors are the icons to guide you to the Entrance Page suitable for you depending on your current situations and interests.

(for Practitioners and Experts)

In each Entrance Page, I am planning to write some introduction at the top which may stay for some years, and I show a list of selected recommended articles among the articles so far posted in the present site.  Every such article is introduced briefly and is accessible with one click of hyperlink icons.   I believe the present site has become much more friendly for you with these Entrance Pages, which guide you to the real treasury of interesting and useful articles.

*** Editorial (Toru Nakagawa): The General Index page of this site provides the one-click access links of all the articles posted for these 16 years.  Since it becomes so large, I have divided it into the following 4 pages:  (A) Main and Editorial, (B) References (books, links, news, software tools, etc.), (C) Papers (papers, case studies, introductory articles, course materials, etc.), and (D) Forum (conference reports, communications, etc.).  Posted in Japanese, but not ready in English. (Sept. 25, 2014)

*** Editorial (Toru Nakagawa):  For making this Web site familiar & friendly for readers, 4 Entrance Pages have been introduced.  They are accessible from the top page and list selected, many articles with brief introduction and links for one-click access:  Entrance pages (1) for children and highschool students, (2) for students and the general public, (3) for engineers and researchers (new to TRIZ), (4) for practitioners.  Already posted in Japanese , but will be by the end of Septmber in English. (Sept. 7, 2014)  Brief introduction notes are attached to all the articles listed in the 4 Entrance pages.  I am working hard to make the 4 Entrance pages in English before I come to ETRIA TFC 2014 on Oct. 29-31.

Announcement: Publication Announcement of the Japanese Edition: Umakant Mishra's "Treasury of Inventive Ideas for Information Technology & Software - Classified with TRIZ Inventive Principles" (Toru Nakagawa (CrePS Institute)) (Aug. 29, 2014)

Authored by Umakant Mishra (India), Japanese translation by Toru Nakagawa (Supervising translator), Yoshihisa Konishi, Toru Shonai, Masatoshi Hotta, and Takuo Maeda, Published by the CrePS Institute, on Aug. 25, 2014.  Printed Edition: Soft cover, B5 size, 340 pages, 4000 yen + tax, Print-on-Demand at DLmarket site. Downloading Edition: PDF, 2500 yen + tax.
Please see the page of the Series , flyer of the series, and flyer of this volume

This book is principally dedicated to people involved in IT and software, as engineers, researchers, PC users, etc. The author collected about 3000 cases of IT/SW solutions from US patents and other technical sources, and interpreted the essence of their solution ideas, and classified the cases with the viewpoints of the essence of ideas by use of TRIZ 40 Principles.  In each of 40 chapters, meaning of a Principle, benefits and application situations, and various application cases of IT/SW technology/techniques are described to clarify how the solution ideas may be generated from the Principle.  Though the 40 Principles in TRIZ were established in the era of 1960s when the computers and software were not yet developed well, they have been found to very well explain or support the ideas of many inventive cases in the field of IT and software.  Mishra's book is a wonderful demonstration of turning a huge complex accumulation of technical knowledge into a treasury of essence of ideas.

-- TRIZ Forum: From Readers : Discussions on "TRIZ and Lean (and others)" (Toru Nakagawa (OGU), Yoichi Hasegawa, Osamu Kumasaka, Toshihiro Hayashi, Masao Ishihama (Kanagawa Inst. of Tech.), Tomomi Murata (Kita-Kyushu City Univ.), Naohiko Takayama (Shimadzu)) (Jul. 13, 2014)
Inspired by the paper "Lean-TRIZ instead of TRIZ-Lean" by C.M. Thurnes et al (Germany), we in Japan recently have some active discussions among the readers of this site.  In the Japanese page, email discussions among the seven persons are posted, while in the English page Nakagawa's messages and Takayama's Mind Map are shown.
On reading the paper, Nakagawa has found a lot for us to learn, think, and act, and wrote Editor's Note (PS) in the Japanese page, which is now translated into English.  Hasegawa responded to it intensively especially with a survey of the historical relationships in the development of Ford mass production system => Toyota production system (or Lean engineering) => TOC (Theory of Constraints).  Hayashi discusses the differences in the purposes of Toyota production system and TRIZ problem solving methodology and argues not to discuss them like alternatives.  Takayama shows the complementary relationships between TRIZ and Six sigma and suggests to clarify such relationships between TRIZ and Lean.  Nakagawa briefly reported about an open lecture by Toyota CEO Chairman Mr. Takeshi Uchiyamada on "Development of PRIUS".  He was the chief engineer of the PRIUS development project.  The ways of developing PRIUS were utterly different from the ordinary Toyota ways of developing new cars, and almost entirely opposite of Lean engineering, he says.   

-- Announcement: Publication Announcement of the Japanese Edition: Larry Ball's "Hierarchical TRIZ Algorithms -- Illustrated Course Material from Novices to Experts" (T. Nakagawa (CrePS Institute)) (Jun. 30, 2014)
Authored by Larry Ball, Japanese translation by Toshio Takahara and Toru Nakagawa, Published by the CrePS Institute, on Jun. 30, 2014.  Printed Edition: Soft cover, B5 size, 208 pages, full color, 4200 yen + tax, Print-on-Demand at DLmarket site.  Downloading Edition: PDF, A4 size, 208 pages, 2400 yen + tax, Digital downloading at DLmarket site.
The main body is the 160-page course materials posted in the "TRIZ Home Page in Japan" in 2006-2007 in Japanese translation .  In front of it, the book contains the introduction and the slides with annotation of the Keynote Lecture presented at Japan TRIZ Symposium 2007, as well as the new Preface by the author .  For making the most of so many illustrations, all pages are printed in color.
This is an excellent textbook of modernized TRIZ.  The author advocates that the decisions in the product development process should follow the logical pre-post relationships. The principal stages should be: Business and market needs => What system does => Identify pivotal functions => Idealize functional components => Idealize attributes of functional components.  These stages form the hierarchy of decisions, and hence a consistent flow of procedures.  During the processes of idealizing the functions and attributes, there appear various problems and contradictions, for which TRIZ tools can be used effectively.  Especially, the author demonstrates a large number of viewpoints of separation of Physical Contradictions, beyond classical TRIZ tools.  There are full of illustrations of small cases for explaining the concepts/processes.  The textbook is easy to understand and enjoyable for beginners, and yet is challenging for experts.

-- TRIZ Introduction Paper:  "Hierarchical TRIZ Algorithms" and Its Further Development (Larry Ball (USA), Japanese translation: T. Nakagawa)  (Jun. 30, 2014)
Preface for the Japanese Edition of Larry Ball's "Hierarchical TRIZ Algorithms", published by the CrePS Institute.
A 7-page Preface newly written down by the author for the Japanese Edition.  "Hierarchical TRIZ Algorithms" was originally posted in the TRIZ Journal in 2005-2006 and was presented in his Keynote Lecture at Japan TRIZ Symposium 2007.  The present article describes its essence reflecting his further development.  He has decomposed all the TRIZ tools together with various other methods related to product development and market development, and has reorganized them into an integrated process.  The guideline for the reconstruction is to clarify the input/output information of processes and to follow the logical pre/post relationships among the processes; he calls it a hierarchy of decision and finds a hierarchical algorithms for product development.  There are cases when an engineer comes up with an idea of a product, draws a prototype design, and requests for the funding.  Such cases fail very often, as statistics show, because he has started the project at a down stream after arbitrarily assuming the information to be decided at upper streams, the author says. The Hierarchical TRIZ Algorithms advises the transfer from 'selling what we can make' to 'making what we can sell'.

-- TRIZ Paper:  Lean-TRIZ instead of TRIZ-Lean (C.M. Thurnes, F. Zeihsel (Germany); Introduction & Japanese translation (T. Nakagawa))  (May 31, 2014)
An excellent paper presented last October at ETRIA TFC 2013.   Recently in many companies in Germany the "Lean" (i.e. Toyota's production/development system) has been introduced actively.  Even though Lean and TRIZ are the methodologies having the targets in common, in fact Lean practitioners rarely use TRIZ even though they are aware of it.  Is there any way to integrate the two methodologies, or for TRIZ to play a significant role in the Lean situations?  
Initially the authors proposed and tested the "TRIZ-Lean" approach where the TRIZ principles (e.g., Inventive principles and ideality) are explained or concretized with the ideas and examples in Lean.  But Lean practitioners rarely found its significance, saying "Lean is good enough without TRIZ". 
Then they found a new approach, "Lean-TRIZ", where in the Lean prevailing situations TRIZ should be used at the Lean's blind/weak points for supporting Lean.  More concretely, the problems which are recognized as 'necessary wastes (NVA)' in Lean are defined as contradictions and are solved with ordinary TRIZ tools.  In the Lean product development process, several TRIZ tools are used.  On the occasions of 'events' in Lean, TRIZ sessions/workshops fit well to work for these purposes. The Lean-TRIZ approach has been tested and has obtained positive evaluations by Lean practitioners.  In practice, the authors advise to respect the Lean philosophies such as 'Test to design' and 'Set-based concurrent development' and to perform TRIZ in relatively short subsessions.  
In the Japanese page , I posted the paper (HTML), slides (PDF), my introduction, and some of my thoughts.  In the English page, only Nakagawa's introduction to the paper is posted; no links to the paper and the slides because they are not yet publicized by ETRIA. 

-- TRIZ Paper:  Freeform Innovation and Ideative Energy (S. Saleem Arshad (Australia))  (May 14, 2014)
'Freeform Innovation' proposed here by the author is a simple and powerful process for generating creative ideas, as is explained and demonstrated with a simple example.  In this concise paper of 10 pages we can understand the basic approach of FI, which has just a two-step structure, i.e., 'Active Observation' and 'Active Thinking'.  The process is driven intuitively and effectively with the emphasis of improving/adding functionality.  In combining and then uniting the ideas/functions of A and B, the author uses the notations like A+B and then (AB).  The present paper contains some more new terms and new concepts, e.g., Ideative energy (on the user side and on the product side), Flow of ideative energy, etc.  They must have a wealth of potential for further investigation and discussion.

-- TRIZ Paper:  Understanding Secrets of Sustainability through TRIZ Philosophy (Umakant Mishra (India))  (May 14, 2014)
A clearly written overview paper discussing on the 'Sustainability' in a general and conceptual level. The philosophy (not individual tools) in TRIZ has guided the understanding.  Such TRIZ concepts are: Cause-effect relationships; Super-, Sub-, and Co-Systems; Resources; Contradictions; Ideality; etc. The paper is written in an abstract and conceptual level and yet very clearly to discuss the real problems to solve and goals to achieve the Sustainability. How to achieve the Sustainability still need to be investigated; I wish to read the author's forthcoming paper.

-- TRIZ Paper:  Methodology: From Altshuller’s 76 Standard Solutions to a new Set of 111 Standards (Davide Russo, Stefano Duci (Italy)); Introduction (T. Nakagawa); Japanese translation (T. Takahara, T. Nakagawa)  (Apr. 30, 2014)
This paper was presented last October at ETRIA TFC2013.   G. Altshuller originally developed the Su-Field Modeling to focus down the problem situation into a minimal system model and the Inventive Standards to recommend some suitable solution strategies according to the problem types.  However, for ordinary TRIZ users, his Triad representation looks particular and the system of 76 Standards seems difficult to parse; and hence these two methods have not been used so widely.  The present authors have reorganized these two methods by following Altshuller's original aims: First, the authors adopted the commonly used concepts of functional analysis for modeling the minimal system.  Then the problem situations are classified into the cases of 'Harmful/Excessive action' and 'Insufficient/Missing action' (besides the cases of 'Measurement/Detection' and 'Incomplete minimal system').  Solution strategies for the 'Harmful/Excessive action' are expressed with 6 different verbs: 'Deflect', 'Block', 'Make unable', 'Make insensitive', 'Combine (the system)', and 'Reduce' the harmful action. Similarly for 'Insufficient/Missing action' the strategies are expressed with different 6 verbs.  Such strategies are called 'Actions'.   The Actions can be applied onto the elements of the minimal system in only 4 ways, i.e., 'Add a substance', 'Modify a substance', 'Add a Field', and 'Modify a Field'.  These 4 ways are named 'Suggestions', and are described in more detail by using the information contained in the original 76 Standards. Thus the present authors have proposed a new, reorganized system of Standards, composed of 25 'Action-Suggestion' pairs of solution strategies.  
*** The new system has a simple overall structure and easy-to-understand description of individual Standards.  This is an excellent paper in modernized TRIZ methodology.  I wish that the world TRIZ community accept this new system for wider penetration.

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).
