TRIZ News: "The TRIZ Journal" has been re-launched already under the operation by Darrell Mann (Systematic Innovation, Inc.) (Jan. 30, 2018)

WTSP Project: Starting the preparation of 'A Catalogue of TRIZ-related Sites in the World' (1) Findings through Practices in Japan (Toru Nakagawa) (Jan. 30,, 2018)  (2) For more practical ways of preparation (Toru Nakagawa) (Feb. 7; Feb. 11; Feb. 12, 2018)

For the actual start of preparing 'A Catalogue of TRIZ-related Sites in the World', I am now working to search and collect TRIZ-related Sites in Japan and to write brief introductions to them.   I now realize that we need to handle a huge volume of information, even exceeding my expectation.  Here are some findings and suggestions for our work.  [** Notice: Depending on countries there seem various differences in the options of search engines and in the situations of TRIZ-related sites.  Thus in each coutry, please adapt/modify your practical procedures to meet our common goal.]
For the search of TRIZ-related sites, we should better use Yahoo! instead of Google, with the keyword of 'TRIZ' and with the settings of 'Local area', 'Our own language', and the option of 'Display the link for searching inside the site'. Copy the full results of the search onto a document while keeping the hyperlinks active.
 

For each site shown in the search results, carry out the search inside the site; then we can get the search results of many TRIZ-relevant pages inside the site.  Visit each site actually to take a look at important pages and write a brief introduction to the site. (Description in the Guideline is revised as: 'Single line introduction' ==> 'Brief introduction' (in 2 to 4 lines, in a free format).
Because of much diversity among the sites, we are going to classify them according to their nature into 9 Categories, such as (a) TRIZ information sending sites, (b) Consultants etc. in TRIZ, (c) Academic societies, etc. (d) Universities, etc.   Depending on the nature of the site, quality and quantity of information, and importance, etc., we should introduce important sites closely to some detail, while less important ones just briefly.
There exist many important relevant sites without mentioning TRIZ explicitly. So we should carry out broader searching for them at the second stage.  How to search them and how to arrange them in our (second type of) Catalogue of TRIZ-related Sites are now under consideration by our 'Global Co-editor' Darrell Mann.
Project members are encouraged to start the search and description work in their own country in the manner describe above and in the Guidelines.

On the basis of the policy in (1), a more practical way of describing individual TRIZ sites and list of them has been shown by relaxing the Guidelines. MS Word instead of Excel may be used, and plain text formats may be easier to write than tabular formats.  A Word file  of the 'Selected 120 TRIZ Sites in the World' (composed by Nakagawa in 2008) is going to be used as the sample and base document for updating and enhancement.  Corresponding to this practical ways, the WTSP Guideline is revised partly. (Feb. 7, 2018)

The base document is posted openly in the WTSP platform (https://trizsites.bitrix24.com/~1AshD )   and in this Web site "TRIZ Home Page in Japan" .  File name is: WTSP-ListSItes-Global-Stage0-180210.docx . See the Instructions in the File how to review and revise this Catalog of Sites.   Revised versions of the document will be publicized in the WTSP platform (probably every month or two) and also in this Web site (probalbly in a shorter interval).  (Feb. 11, 2018). 

Another important change in the Membership: WTSP members may or may not use the WTSP platform. Since many people are too busy to learn the Bitrix24 operations, they prefer to use their ordinary tools of MS Word and emails. See the page WTSP (A2) Organization . (Feb. 12, 2018)

 From the Editor:  Message for the New Year 2018 (Toru Nakagawa)  (Jan. 25, 2018)

Greetings from Japan for a Happy New Year 2018!! Wish the year be peaceful in the World, and healthy, happy, and successful for you all.  Posted is an English translation of my New Year Card which I sent to about 200 friends in Japan whom I met before my TRIZ days. 

Happy New Year 2018 !!
Since my retirement of OGU in 2012, I have been continuing my research and proliferation activities on the methodologies of creative problem solving. I am trying to extend application areas of the methodology from technolgies to social/human areas.
At the base of social problems related to poverty, we find the conflicts in arguments for self-responsivility and for mutual help. And further down at the root, I have found the 'Principal Contradiction of Human Culture', as show in the figure (right). The two Principal Principles 'Liberty' and 'Love' do conflict everywhere. 'Ethics' is supposed to motivate and coordinate the two Principles, but it should overcome the basic inclination of 'Obedience' in old 'Morals' and stand on the basis of dignity and essencial equality of every person. The three Principal Principles, i.e. Liberty, Love, and Ethics, should be establlished in every person and every organization/society. 
The swallows in the photo show naturally and sincerely 'Liberty, Love, and Ethics'.
I wish you all for your health and success, and for a peaceful new year.

  TRIZ Forum:  Letters from Readers (Nov. - Dec., 2017)/ Initializing 'World TRIZ Sites Project'   (Dec. 17, 2017)  Index page of "Letters from Readers"

[English page ]  Toru Nakagawa (Japan); Vladimir Petrov (Israel), Shireen Al - Jaouni (Jerusalem), Alexander Theodor Narbut (Ukraine), Mohammad Reza Nouroozi (Iran), Simon Dewulf (Australia), Tan Runhua (China), Oleg Kraev (for Yuri Salamatov) (Russia), Nina Defounga (Germany), Nikolay Shpakovsky (Russia), Valeri Souchkov (Netherlands), Darrell Mann (UK), Davide Russo (Italy), Tanasak Pheunghua (Thailand), Michael Orloff (Germany), Ian Mitchell (UK), Leszek Chybowski (Poland), Ellen Domb (USA), Kai Hiltmann (Germany), T.S. Yeoh (Malaysia), 蔡易坤 (for Prof. Lingling Luo) (China), Yury Danilovsky (Korea/Russia); Eyad Khalifeh (Canada/Israel)
This page ’Letters from Readers' is for recording various communications between readers in the world and the Editor. However, the present page covering Nov.- Dec. 2017 is very unique and devoted for the records of communications mostly issued by Toru Nakagawa for proposing 'World TRIZ Sites Project' and responses to them by many TRIZ Leaders in the world. The Proposals and Invitations of the Project are posted here on Dec. 9, 2017, as an ordinary document so to speak. In the present page, on the other hand, you can see why and how Nakagawa wanted and initiated the Project and how so many people in various countries responded positively to support and join the Project. Such a consensus of necessity of 'World TRIZ Sites Project' certainly becomes our motivation to 'Build a (big) page of TRIZ Sites in the World' and further for us, TRIZ community in the world, to work Together! Connected !!

Prof. Kuchitsu encourages me.  He is Professor Emeritus of Univ. of Tokyo and is just retired officially at the age of 90 and still keeps academic/educational communications with people in Japan and in the world.  H. Sakuma regularly distributes his 'Human Factor Safety Reports' analyzing various accidents/failures.  He categorizes errors in 3 types, i.e., Random errors, Systematic errors, and Sporadic errors.  Education and training is useful against Random errors, and training of design procedures is necessary against Systematic errors; but neither of them cannot prevent Sporadic errors, which come out sub-consciously.  He says Human-Factor solutions have to be trained for preventing Sporadic errors.

Forum (From the Editor): World TRIZ Sites Project: Its Plan and Invitation: Volunteer Project for Connecting TRIZ Sites in the World (Toru Nakagawa) (Dec. 9,, 2017)

Receiving positive feedbacks by a number of TRIZ Leaders, I have sent an official Invitation to the 95 TRIZ Leaders for starting the World TRIZ Sites Project.  Please note, however, that the Project is open for any TRIZ Leaders/Colleagues who volunteer to work for the sake of TRIZ, Together ! Connected!!   The Invitation Letter summarizes the purpose and philosophy of the Project and describes how we are going to work together with the platform in Bitrix24 system in cloud.  Descriptions of individual sites and lists of them are to be made in a bottom-up manner, being structured according to countries, then regions, and finally the whole world, and also being refined through the processes of drafting, reviewing/revising, and publicizing.  The project team is going to be organized in a way to match with the documentation processes.

We eagerly wish you, Leaders and Colleagues in TRIZ (in a wider sense), to join our World TRIZ Sites Project as a voluntary member, or to support us (being outside the Project) by describing your own (or neighboring) TRIZ sites and contributing it to the Project.    The Invitation Letter writes concrete instructions about Membership Application Form, process of opening an account in the platform, templates and samples of site (and list of sites) description, a method for public accessing to our open documents in the platform.

Forum (From the Editor): World TRIZ Sites Project: Proposals: Volunteer Project for Connecting TRIZ Sites in the World (Toru Nakagawa) (Dec. 9,, 2017)

Since 3 weeks ago, I sent a series of emails to 95 TRIZ Leaders (of 33 Countries) in the world.  They are proposals of volunteer work together as 'World TRIZ Sites Project'.  It intends to build a page of listing and introducing TRIZ sites in the world, by the collaboration of TRIZ leaders/colleagues.  I built such a page in 2008, 'Extended 120 TRIZ Links in the World' , but could not update it for 10 years.  Since then I have been advocating a vision 'Global Network of Public Web Sites in TRIZ: A Proposal for Building A Global TRIZ Community' .  The present project will become a practical step forward to such a goal. Our Symbol Mark shows this motive clearly.  Here are the four documents of Proposal, which are made clearer step by step by receiving positive feedbacks:

    Proposal (1)   Please help to Build a page of 300 TRIZ Sites in the World  (Toru Nakagawa, Nov. 21, 2017)
    Proposal (1A)  Let’s Cooperate with the platform of TRIZSites.bitrix24.com (Toru Nakagawa, Nov. 22, 2017)
    Proposal (1B)  World TRIZ Sites Project: Guidelines of Describing TRIZ Sites and Their Lists (Toru Nakagawa, Nov. 27, 2017)
    Proposal (1C)  World TRIZ Sites Project: Organizing the Project Team (Toru Nakagawa, Nov. 28, 2017)

From the Editor: Failures in searching for pages of the present site have been recovered (Toru Nakagawa) (Nov. 16, 2017)

The present site "TRIZ Home Page in Japan" was found to have blocked the page searches by softbots (Google, Yafoo, etc.) since half a year ago due to some mishandling in our Web server; now this error has been corrected.  Internal search of pages was not working nearly 2 years due to unknown causes, but has been recovered today .  I deeply apologize for your  inconveniences for so long time, and beg your patience for some more months until recovering the hit ratio.  I also notice that many backlogs exist, e.g., updating global/domestic TRIZ site links (since 2008), and posting recent development of TRIZ-related software tools, etc.  I wish to have voluteers for supporting this site, and those for operating TRIZ Web sites in different countries/communities for forming 'Global Network of Public Web Sites in TRIZ' .

 Paper: TRIZ in China: TRIZ,The Development And Dissemination In Industries In China (Runhua Tan, China)   (Nov. 5, 2017)

Early October, two international TRIZ conferences were held at the same time; they are ETRIA TRIZ Future Conference (TFC2017) in Lappeenranta, Finland and Altshuller Institute for TRIZ Studies Annual Conference (TRIZCON2017) in Atlantic City, NJ, USA.  Among many presentations, I am much interested in the paper given by 'National Engineering Research Center for Technological Innovation Method and Tool, Hebei University of Technology (Tianjin, China)' at the both conferences.  On my request, Professor Tan sent me his TRIZCON paper and presentation slides.  Thanks to the Author's and Altshuller Institute's permissions, I am very happy to post this paper in "TRIZ Home Page in Japan" both in English and in Japanese translation.

Research and dissemination of TRIZ in China have been developed recently in a surprising speed and extent, we learn, in comparison to the former two reviews: by Zhao Xinjun (Northeastern Univ.) in Nov. 2004 and by Xian-yong Zhou (Southwest Jiantong Univ.) in Nov. 2011 .  According to Dr. Bai, the Research Center is led by Professor Runhua Tan, having about 80 faculty members, about 20 PhD students, and about 80 postgraduate students (corrected on Nov. 7, 2017), and is devoted to research, education, and dissemination of methodologies and tools for technological innovation with TRIZ at its core.  China seems to have many more research centers on innovation methods based on TRIZ, under strong supports by national and regional governments.

The Center has developed 'an integrated system of methodologies for innovation on the basis of TRIZ', in the name of C-TRIZ (Chinese version of extended TRIZ). This paper introduces its overview.
They have been actively disseminating C-TRIZ into industries by using MEOTM (Mass-Engineer Oriented Training Model).  The trainings last for half a year or full year (mostly using weekends) with lessons and real practices.  One or multiple companies are selected first, and then the participating engineers are selected for organizing a training class.  Every engineer has to bring in an 'inventive problem' related to his/her own job or company, and during the training course he/she has to define the problem clearly, solve the problem, and present the results at open oral defence in order to be certified as an 'innovative engineer'. From 2013 till 2016, the center carried out 40 training classes, covering 721 companies, with 3173 participating engineers in total, and produced 1471 certified engineers, they report.

  On the 19th Anniversary of  "TRIZ Home Page in Japan":  (Editor Toru Nakagawa)   (Nov. 5, 2017)

This Web site "TRIZ Home in Japan" celebrates its 19th Anniversary on Nov. 1.  I am very grateful to you all, including authors, translators, and readers in Japan and around the world, for your continuing support.  This site serves as an open forum of information exchange for better understanding and usage of Creative Problem Solving Methodologies.  Initially, I intended to introduce TRIZ, a Russian-based methodology for mostly technological areas, but year after year the scope of this site became wider and deeper along with the development of such methodologies.  TRIZ itself has evolved to wider application including business and marketing, and has been spreading widely in the world.  My own research has extended to USIT as an easy-to-learn TRIZ, the Six-Box Scheme as a new paradigm of creative problem solving, and CrePS (General Methodology of Creative Problem Solving) which intends to integrate and unify various methods by using the Six-Box Scheme.  Since 2015, I have been trying to apply them to social problems, especially for revealing the fundamental contradictions in Human Culture and investigating the relationships of Liberty-Love-Ethics.  Thus the scope and contents of this site have been slightly changing as a result of natural evolution.

This site is meant to openly publish information and communications 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 people.  I envisage that Pubic Web Sites built in different countries/communities will form A Global (TRIZ) Community with much reduced language barriers Four Entrance Pages have been installed in 2012 for your easy access to articles.  The number of visits since November 2005 is (on Nov. 5) 233,673 (increasing by about 3,400 for the last 1 year) to the top page in Japanese and 41,640 (increasing by about 1,200) to that in English.  I wish this Home Page be useful for you readers to solve your various problems.  Readers' contributions either in English or in Japanese are heartily welcome.

 

 Keynote: TRIZ for Science: Evolution of Scientific Instruments & Methodology of Inventiveness in Applications to Science (Andrei A. Seryi, UK)   (Oct. 17, 2017)

This impressive Keynote Lecture was given by Professor Andrei Seryi at ETRIA TFC2017 held two weeks ago in Lappeenranta, Finland.  Under his kind permission, I am posting his presentation slides (110 pages in PDF ) here in HTML with (new) section headers and GIF images for easier overall understanding. 
(Note: ETRIA is working for publishing the TFC2017 papers in a book/journal from some publisher, thus stopping the authors to post their papers/slides at any Web site.  Keynote lectures, however, are not included in the publication plan and hence are allowed for posting at a Web site by the author's decision.)

Professor Andrei Seryi  graduated Novosibirsk State University (NSU) Physics Department in 1986 and worked in Russia, France, USA (Fermi lab and Stanford Linear Accelerator Center (1999-2010)) in the fields of high-energy physics, and since 2010 he is Director of John Adams Institute for Accelerator Science , the University of Oxford, in UK.  As a Director he has become to consider more seriously about the usefulness of high-energy physics and to teach creativity methods in scientific research.  So he met TRIZ again (since his childhood) and found its depth.

The present Keynote contains detailed figures of scientific instruments for cutting-edge physics, and you may feel difficult to understand the background physics, so do I.  However, the author shows the essential points of discussion clearly and plainly for people having interest in science in general.  E.g., be careful (and needs methodology) in the prediction of future, evaluate different research directions not only for fundamental knowledge but also for usefulness and the costs.
Author's insights of using TRIZ are deep.  In explaining Inventive Principle 35 'Parameter change', he demonstrates (in place of simple parameters volume V and surface area S) the ratio V/S inspires us much more while changing the parameter value.  He also mentions that Cloud chamber and Bubble chamber, both for detecting high-energy particles, are an example of TRIZ concept of 'System and Anti-system' and that if scientists were familiar with the concept, Bubble chamber could have been invented much earlier. 'Transition to super-system' is also an important TRIZ concept in understanding the evolution of systems.  New methods/tools are implemented as a system by assembling many components, and then they become useful only when working as a part of larger systems (i.e., super-system) for social, business, technical, etc. purposes. 

"TRIZ can be very useful for science, as an inspiration, as a very efficient toolbox, as a way to connect different disciplines, as a new way to see the world" -- This is the conclusion by Professor Seryi.  It is a testimonial by a leading scientist who has achieved a lot in physics and mastered TRIZ.   We wish TRIZ be understood widely and used in practice in the field of science, by many researchers and engineers.
--- TRIZ can support science well in the aspect 'scientific revolutions are tool-driven', as shown in this keynote.  TRIZ can support science also in the aspect 'scientific revolutions are concept-driven'? -- This is an open question.  Please refer a discussion page .

 TRIZ/CrePS Paper (Social problem): 'Liberty vs. Love': The Principal Contradiction of Human Culture (2) The 'Liberty vs. Love' Contradiction and 'Ethics' at the Personal Level (Toru Nakagawa)   (Sept. 28, 2017)

Recently I made presentations at three conferences, i.e., Japan Creativity Soc. Conf. (Sept. 9-10, 2017 in Yokohama), Japan TRIZ Symp. 2017 (Sept. 21-22, 2017 in Tokyo), and ETRIA TRIZ Future Conf. TFC 2017 in Finland.  The presentations have the same title and similar contents, but are adjusted to their different audiences, different requests of documents and submission dates.  I have been working on this social issue for these 2 years.  You may trace my study in the articles posted in this Web site, e.g. (Nov. 2015), (Mar. 2016), (Apr. 2016), (Nov. 2016), (Jan. 2017). 

The Basic Hypothesis obtained in this study can be summarized as follows (Toru Nakagawa, Sept. 26, 2017):
(1) Ethics (and its deepening) is the 0th Principle of Human Culture. Deep inside the human heart, Ethics serves as the guideline to direct internal desires from Bad Will toward Good Will. The Contents of Ethics, i.e. 'What is Good, and What is Bad', are acquired later in life through the society, and hence are different depending on history and on society. However, 'the internal ability to distinguish Good from Bad deep inside the human heart', which I call Conscience, is supposed to be intrinsic for humankind and hence serves as the fundamental basis for the Human Culture. The concepts of 'Essential Equality of every person as a human' and 'Fundamental Human Rights' have become clearer through the Human history.  Essence of the 0th Principle is the principle that Every person has the rights for pursuing Happiness.
(2) The First Principle, Liberty, is 'To decide and act for oneself and to live', and it aims at Winning in Competitions. It brings with Reformation and Creation on one side, while Ruling and Conservation by the Winners on the other side. Essence of the First Principle is 'To pursue My (or Our) own Happiness and Interests'.
(3) The Second Principle, Love, is 'To love one's own children, family, and neighbors and to help and protect them', and aims at self-controlling one's Liberty and at serving and coordinating with others.  For protecting one's Family (in a wider sense), Love is apt to generate conflicts with the Outsiders.  Essence of the Second Principle is 'To pursue the Happiness and Interests of All the members'.  Here, the range of people expressed as 'All the members' is an issue, which should be widened universally as a goal of Human Culture.
(4)   There exist various Conflicts/Contradictions inside Liberty, inside Love, and between Liberty and Love. Types of such Contradictions are listed.
(5)  When the understanding of Ethics is poor, i.e., when one is motivated by Bad Will (or selfish mind), Liberty as well as Love are greatly spoiled in their spirits and actions and the 'Liberty vs Love' Contradictions emerge severely.  Therefore, the installation of Ethics in the minds and actions at the personal level and in the actions and social rules at various social organizational levels is the important keys to reduce and resolve the Principal 'Liberty vs. Love' Contradiction of Human Culture. The core of the Ethics is the spirit of 'Essential Equality of every person as a human'.
(6)  In short, Liberty (for pursuing My (or Our) own Happiness) and Love (for pursuing Happiness of All the members) are both motivated and hence can be coordinated by the Ethics (i.e., the 0th Principle that Every person has the rights to pursue one's Happiness) so as to reduce/resolve the Principal Contradiction 'Liberty vs. Love' of Human Culture.

On request from S. Litvin, I wrote a document of my whole activities related to TRIZ and Creative Problem Solving Methodology at OGU, containing research, education, application, and proliferation (See a separate page: ). 
For writing Introductions of ETRIA TFC2016 papers, I sent a request to many TFC2016 authors for sending me their presentation slides.  And I received a message from ETRIA President to note the copyrights issues of the papers.  I confirmed that Papers in English are not posted/cited because ETRIA is going to publish them officially in spring NEXT year and that Slides in English may be posted/cited under Author's permissions and Papers and Slides in Japanese translation are allowed to be posted/cited.  I explained these points to the Authors and posted my Introductions of 17 TFC2016 papers on Mar. 30 under their permissions.
W. Hessler suggested me to make my Web site design easier to read and more user-friendly, especially for beginners.  I want to make this Web site, however, up-to-date, reliable, and high-quality source of information of TRIZ and Creative problem solving methodology in general.  For making such an intention compatible with user-friendliness, I have been trying to implement various measures; they are summarized here again in reply.  Probably it will be most effective from now on to insert more photos (such as people in conferences, authors of articles, flowers in seasons, etc.).  I would like to ask you, the readers, to contribute articles and give suggestions to this Web site.

[Japanese page ] Mr. O; Akihiro Katahira; Toru Nakagawa (OGU)
Mr. O, who is going to introduce TRIZ in his company, asked me about the position of TRIZ among various idea generation methods.  I replied that methods of creative problem solving are more important than simple, short-cut oriented idea-generation methods.  Such methodology has been developed recently by improving/generalizing TRIZ.  The concept of 'Six-Box Scheme' and easy process USIT should be learnt, by using USIT Manual and USIT Case Studies. I just introduced the essence of what are discussed repeatedly in this Web site.

  Case Study of TRIZ Promotion: A long-term strategy to spread TRIZ in SMEs. Analysis of Bergamo's experience (Davide Russo, Daniele Regazzoni, Caterina Rizzi (Italy); Japanese translation: Toru Nakagawa)  (Feb. 14, 2017) 

Presented at ETRIA TFC 2016 on Oct. 25, 2016 at Wroclaw, Poland.  In the English page , presentation slides are posted both in HTML and in PDF.  The paper will be made accessible with a link to Elsevier's Science Direct whenever openly published.  In the Japanese page , the full paper and the presentation slides are posted in Japanese translation.

The TRIZ research group, formed in the University of Bergamo, educated students of Master courses with the TRIZ methodology, and worked to spread TRIZ in the industrial community in collaboration of Bergamo Chamber of Commerce.  This is a valuable report of the activities, which contributed to stimulate and enhance the intellectual properties and innovation in the regional community prevailed by SMEs.
Typical models of promoting TRIZ are based on success stories in big enterprises.  In Italy, however, big companies (with over 250 employees) are very few (0.1%) while very small companies (with less than 10 employees) are prevailing (95%).  Thus the Authors built a new model of responding to the demands of SMEs first in collaboration with Chamber of Commerce.  Under a long term strategy, they provided services of teaching, training, and consulting the owners and engineers of SMEs on the topic of Intellectual Properties first and TRIZ later.  In 9 years they have achieved remarkable results.

After a few years of interval, I have made up my mind to write 'Personal Reports' of some important TRIZ conferences, starting with ETRIA TFC2016.  In the field of TRIZ, several international conferences and several tens of regional/domestic/company-organized conferences are held every year.   Papers/presentations at such conferences are mostly not known even for people interested/involved in TRIZ.  Overviews of the papers and introductions to good papers would be useful for promoting TRIZ, only if appropriate reviews were done.  Knowing the responsibilities and burdens, I will do my best to write 'Personal Reports', as I did before (Conference Reports (1) through (30)).   

The present page in English is just a skeletal of my Personal Report, containing only a list of all the papers categorized with topics. I have just posted a Japanese page having very-brief introductions to all the papers, which are written after reading Authors' Abstracts and presentation slides (made available to TFC2016 participants). After reading papers closely one after another from now on, I am going to write introductions to them in English. It will take two months or so for me to finish and post my Personal Report in English.

Introductory: 'Liberty vs. Love': The Principal Contradiction Inherent throughout the Human Culture (Toru Nakagawa) (Jan. 13, 2017) 

This article was written last October and published in the Bulletin of YMCA at Univ. of Tokyo last December.  Starting with my self-introduction, I briefly trace my work for these 20 years on methodology of creative problem solving, and explain the big topic in the title on which I have been working since last year.  I explain how I have been working as a researcher, initially in physical chemistry and later in informatics, to understand and develope 'Methodology of creative problem solving' (namely, methodology of research and development).  I found the Six-Box Scheme as a new paradigm in science and technology.   For extending its application to social problems, I chose to work on the problems of poverty in the Japanese society.  Underlying people's arguments whether to help the poor, I found the conflict between the emphasis on Liberty and that of Love.   Then I realized that Liberty vs. Love is much more basic, and actually is the Principal Contradiction unsolved throughout the history of Human Culture.   I have shown here a hypothesis of the Liberty vs. Love Contradiction in its skeletal form.

The idea that there exists a basic conflict (or contradiction) between Liberty and Love is not difficult to understand in itself.  You can easily show such examples in our everyday life, in our society, and in the international politics, etc.   We have been taught simply, however, "Liberty and Love are both important. So you should respect both of them. They should be compatible."  Nobody dared to say clearly "Between Liberty and Love there exists an intrinsic conflict. That is the most basic, Principal Contradiction of Human Culture."  The present approach is based the spirit/philosophy of TRIZ, i.e., "Understanding contradictions clearly is the basic way for us to solve the contradictions (or make them compatible)".  To understand the real situations and desirable directions concerning to this Principal Contradiction in the fields of humans, organizations, societies, and the world is a huge task for us to work from now on.

 From the Editor:  Message for the New Year 2017 (Toru Nakagawa)  (Jan. 13, 2017)

Greetings from Japan for a Happy New Year 2017!!
 Wish the year be peaceful in the World, and healthy, happy, and successful for you all. 

Posted is an English translation of my New Year Card which I sent to about 200 friends in Japan whom I met before my TRIZ days.  In the Japanese page, I wrote a summary of my work in 2016 and a brief message of my thought about the situations in Japan and in the world, especially quoting the one I wrote last July after the election of Japanese Parliament.

    CrePS Research Note: Six-Box Scheme Representation of Published Papers (1) 18 Papers by Toru Nakagawa (2000 - 2016) (Toru Nakagawa)  (Dec. 27, 2016) 

18 papers which I published at international/domestic conferences every year since 2000 are represented in the overview format of the Six-Box Scheme, and are shown here together with their Abstracts, both in HTML (images) and in PDF .  You may understand, I hope, the concept of the Six-Box Scheme, ways of representing works in the Six-Box Scheme overview, and also a history of my work for developing them.

The Six-Box Scheme is a new paradigm of creative problem solving, which I found in 2004 in my study of TRIZ and USIT and I have been promoting actively in a much more general context since 2012.   For the purpose of demonstrating the Six-Box Scheme, I have been trying till recently to make new case studies where various types of problems are solved along the Six-Box Scheme with some methods like USIT.   The demonstration has been proceeding only slowly with a limited number of case studies.  I now realize, however, that almost all serious intellectual activities and their results can be described properly in the Six-Box Scheme.   Thus I made trials to describe a selection of my papers which I published in 2002, 2004-2005, 2012, and 2014, in the Six-Box Scheme.   Since the representations were found meaningful, I have described my 18 papers published every year from 2000 to 2016 in the Six-Box Scheme, as you see here.

Every published paper can be represented properly in the Six-Box Scheme, and should be worthy of doing so.   The Six-Box Scheme has such generality as a basic paradigm of creative problem solving.   Some of the papers, of course, emphasize some parts of the Six-Box Scheme and skips some other parts.  That is all right. The Six-Box Scheme representation plays the role of a template for describing intellectual activities/works, just like the standard format for filing patents.

    Training activities:  Conducting a Training Seminar on 'How to Prepare and Write Reports', (Toru Nakagawa, OGU) (Nov. 28, 2016)

Every year since July 2010, I have conducted a training seminar on 'How to prepare and write reports' for 2 days (12 hours) to 50 nurses at Wakayama Prefectural Nursing Association.  The training seminar is a part of the First Level (for 150 hours) of the Course for Certified Nurse Administrators, organized by Japan Nursing Association. 
For the training text I use my article 'How to Prepare and Write Reports: Preparation of the Contents, Building the Structure, and then Writing Sentences', published in Communications of OGU and posted here on Oct. 10, 2010.  It contains (a) my OGU Lecture Note 'How to write a report' (explained in a top-down style), (b) 'Practical guidelines for writing documents' (explained in a bottom-up style), and (c) a one-page summary covering both (a) and (b).  [Sorry but no English pages of these.]  I also give a presentation on 'How to Think for Creative Problem Solving' , with 3 case studies; i.e., (d) 'How to fix a string shorter than the needle', (e) 'How to improve classes', and (f) 'Thinking over the poverty problem with visualization and contradiction finding'.  The Six-Box Scheme paradigm for creative problem solving is illustrated with these case studies.
Group exercises are also carried out. I use excerpts from OGU students' reports and ask the nurse trainees to brush them up, then I show my revised versions and my comments to the students, which are posted here on March 11, 2010.  Then we go ahead to review and improve the nurses' own reports which were submitted beforehand for the course on the theme of 'Situations and tasks at my own work place'.  2 groups (of 5 members) work on a report in parallel.  The trainees are requested, step by step, to read the reports closely, to check/improve the sentence expressions, to reconsider the paragraph structures, to understand/think on the problem situations, causes of difficulties, directions for solutions, etc,, and finally to present the 'Situations and Tasks' in place of the report author with max-4 slides, even extending the authors thoughts, if possible.   15 reports (among 50) are reviewed in 3 cycles.  Thus the group work serves not only for learning better writing but also for understanding better process of problem solving as the basis for preparing the contents of reports.  --- This training program has received much appreciation, to my pleasure.

Souchkov for preparing the Japanese translation of his article on 'TRIZ for Business and Management', and learned about a free software tool 'yEd' for drawing diagrams. He mentions that he delivered a keynote lecture at a Russian domestic TRIZ conference to 350 participants and that in various countries in the world TRIZ proliferation activities are in good progress. C. Cempel is interested in the contradictions between Liberty and Love and further with Equality.

Y. Hasegawa, reading Nakagawa's booklet of the Visualized diagrams of the LLE book, considers about possible measures of the social welfare, and the importance of not producing people who have to depend on the welfare. S. Sadahiro suggests that images are more important than words in the Thinking World of the Six-Box Scheme, but  I explain that Thinking World is a collaborative work place where both of them are used and recorded.  Y. Yoshida asked about the TRIZ usage in material development (but not chemical engineering).  I suggested a few references and some possible (but not well explored) approaches.  T. Itoh appreciated my work on the poverty problem especially with the visualization method.

A. Harada mentions that the slogan of 'Liberty, Equality, and Love' of the modern world since the French Revolution may need to be reconsidered. Nakagawa responded: "Equality is a principle at the base of Fundamental Human Rights and hence at the core of Ethics. Since both Liberty (The 1st Principle) and Love (The 2nd Principle) are motivated and developed by Ethics, we may regard Ethics as The 0th Principle of Human Culture."  T. Maekawa communicated about National Contest of Statistical Graphs for Elementary and Junior High School Pupils; 2 pages of his communication are posted in small images. The entrance page "Let's enjoy 'Think & Try' !" of the present home page has not been updated for over a year. I wish to have some voluntary co-Editor for this part. T. Torii writes "Toshio Takahara's theory is great for understanding contradictions systematically. I wish you dig much further concerning to the Principal Contradiction 'Liberty vs. Lave'."  Professor K. Kuchitsu (who guided me as Associate Professor and Professor during my years of undergraduate, graduate, and Assistant) evaluated my recent article on 'How to prepare and write reports'. T. Maekawa communicated again about his episode that when he was a freshman at a company his boss guided him uniquely to write a report everyday; first a line, then a few lines, and finally a page.

 TRIZ/CrePS Presentation (Social problem): TRIZ/CrePS Approach to the Social Problems of Poverty: 'Liberty vs. Love' Is Found the Principal Contradiction of the Human Culture (Toru Nakagawa)   (Nov. 12, 2016) 

This page posts the slides (in HTML and in PDF ) presented at the ETRIA TFC2016, held on Oct. 24-27, 2016 at Wroclaw Technical University (Poland).   My presentation is a slight revision of my talk at Japan TRIZ Symposium held last September .  My full paper will be accessible in the official publication in Procedia CIRP (by Elsevier), as planned next February.  Outline is:

(1) Trying to apply TRIZ/CrePS methodology to social problems, I have chosen the poverty problem in the Japanese society (especially among the elderly) as the theme. 
(2) I chose Takanori Fujita's book "The Low-living Elderly" as the source reference, and visualized the logics of the book by using Fuda-Yose Tool.
(3) By critically reviewing the 82 Customer reviews on the book, I recognized an unsolved big problem underlying the people's arguments about the 'Win or Lose' and Mutual aid in the competitive society.
(4) Digging down to their essence, I recognized the conflicts between Liberty and Love.  Liberty (i.e., to decide and act for oneself, and to Live) is the First Principle, while Love (i.e., to love one's children, one's family, and one's neighbors, and to Help and Protect them) is the Second Principle of Human Culture.  Nevertheless, Liberty vs. Love has been the Principal Contradiction inherent through the Human Culture. 
(5) Even though Human Culture has been trying to solve it, the Principal Contradiction still exists everywhere, emerges and grows newly everywhere, and is getting even more difficult to solve, I realized.  I have recognized four main reasons of difficulties.
(6) Considering these four reasons one by one, we should understand the mechanisms of the Principal Contradiction and think over the solution directions.
The present study is guided by the TRIZ philosophy of contradiction and the CrePS process of creative problem solving.
