[1] TRIZ Forum: Conference Report (31):

Personal Report of The 16th ETRIA TRIZ Future Conference (TFC 2016),

Held on Oct. 24-27, 2016, at Wroclaw, Poland

Toru Nakagawa (OGU)  

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, unfortunately, 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 I wrote 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.

[2] 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 University of Bergamo, Italy);

Japanese translation: Toru Nakagawa  

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.

[3] TRIZ Forum: Letters from ReadersDec. 2016 - Jan. 2017

[English page] Czeslaw Cempel (Poland), Ellen Domb (USA), Hugo Sanchez (Nicaragua), Shahid Saleem Arshad (Australia); Toru Nakagawa

Communications between Cempel and Nakagawa, on 'Liberty vs Love', especially that Ethics (including Equity) is the 0th Principle.

Domb and Sanchez sent me wishes and encourage the work of this Web site.

Arshad supported me on the work of 'Liberty vs. Love'. He attached a picture of homeless Japanese citizens just post-war in 1945. Nakagawa responded mentioning the hidden nature of poverty in modern countries

[Japanese page ] Akihiko Ikeda, Tomomi Murata, Kouichi Miyazato, Tetsu Sadahiro, Munehiro Shimada, Mikiya Kobayashi, Toru Nakagawa

Murata sent me his greetings together with Haiku (Japanese short poems) he composed.

Miyazato encourages me to keep this site as a platform where Gemba leaders can study.

Sadahiro asks me about how engineers' use of their knowledge and experiences is related to the Six-Box Scheme.

Shimada sent me his newly published book: "How Do We Want to Die?" (Author: M. de Ridder,

   Translation into Japanese: M. Shimada and W.R. Ade).

Kobayashi sent me his sympathy on the 'Liberty vs. Love' issue.

Best wishes,

Dear TRIZ Colleagues,

A Happy New Year 2017 !!

"TRIZ Home Page in Japan" has been updated

   today (dated Jan. 13, 2017) in English and in Japanese pages.

       The Principal Contradiction Inherent throughout the Human Culture

[1] From the Editor: Message for the New Year 2017

                         (Toru Nakagawa)

   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.


Happy New Year 2017 !!

Since my retirement of OGU in 2012, I am continuing my research and proliferation activities on the methodologies of creative problem solving.  

I have reached a conviction that the Six-Box Scheme is the new paradigm of creative problem solving in general, including technological development in industries, advanced research in academia, issues of social problems, etc.

Starting with the visualization of the logic of "The Low-living Elderly" book written by Takanori Fujita, I worked on the issue of poverty in the Japanese society.

In the issues of poverty and welfare, there always exist the conflicts of arguments between self-responsibility and mutual help.  

At the root of them, I have found the conflicts between the two basic Principles, i.e., Liberty and Love.

Liberty vs. Love is the Principal Contradiction inherent in the Human Culture, and emerges and exists everywhere unsolved in the history.  

Ethics, containing the Fundamental Human Rights (having Equality at its core), can motivate and coordinate Liberty and Love together.

Thus at the personal (and inter-personal) level and at various social levels, the relationships among Liberty, Love, and Ethics should be revealed in their actual as well as desirable situations.

And such understanding should be shared widely as the Human Culture.

--- This is the understanding of the problem and its hypothesis I have just obtained at the age of 76, and it forms an important starting point for the big task of creative problem solving.

I wish you all for your health and success, and for a peaceful new year.

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.

[2] Introductory: 'Liberty vs. Love':

   The Principal Contradiction Inherent throughout the Human Culture

                      (Toru Nakagawa)

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 develop '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.

Best wishes always,

Toru Nakagawa
