World WTSP Catalogs: World TRIZ Basic Index (Toru Nakagawa) (Aug. 4, 2019)(Aug. 8, 2019)

This is the basic Catalog (or Core Catalog) of the World WTSP Catalogs.  It shows the sites in TRIZ in the world with the evaluations of ◎(Most important, about top 30) and ○ (Important,about top 100).  60 sites are arranged after categorizing them with the Roles of site.  The Index is shown in a tabular form.  By clicking the site code (or site number) in the table, description of the site will be displayed.  This is a preliminary version containing the data from only 4 countries (Japan, Malaysia, China, and Russian region) and 2 top-down surveys (TRIZ in the world, and TRIZ in USA).  By getting contributions from many more countries (hopefully 30-40 countries) and by improving the site descriptions, we are sure that this core part (World TRIZ Basic Index) of World WTSP Catalogs can tell us rich and useful information about TRIZ activities and their achievements in the world. 

World WTSP Catalogs: World WTSP Catalogs Top Page (Toru Nakagawa) (Aug. 4, 2019) (Aug. 8, 2019)

This is the top page of our new World WTSP Catalogs !!!.   The World WTSP Catalogs form a system of various Indexes to the descriptions of sites.  Its structure (for the users) is illustrated in the following figure.
On the basis of the data of Table of sites and Descriptions of sites contributed by various country Teams and by Top-down surveys, the World WTSP Catalogs provide us with additional Indexes which show the sites in the world after various ways of categorization and rearrangement. We have just built the World TRIZ Basic Catalog, showing ◎ and ○ sites in TRIZ in the world.  We are going to build a few more Indexes containing the ◎○□ sites and also the sites around TRIZ

World WTSP Catalogs: Source Documents of the World WTSP Catalogs (Toru Nakagawa) (Aug. 4, 2019) (Aug. 8, 2019)

This page manages the source documents contributed by various WTSP Teams to the World WTSP Catalogs.  Such documents have to be examined to make sure that they match with the requirements of the mandatory information, suitable formatting, hyperlinks & anchor points, and working as a small Web site of each Team/Case.  For the document management, the structure of folders of documents has been designed in the figure shown below.  This design ensures easy handling and consistency of data throughout the stages of initial checking, preparation of World Catalogs, usage of Catalogs, and maintenance/updating the Catalogs.

WTSP Working Material: Flat Table of TRIZ sites Written in Russian Language in the world (Michael Orloff) (Aug. 4, 2019)

I received this manuscript from Michael Orloff on Jul. 24, and sent [WTSP] Letter (12C-2ru) to many Russian speaking TRIZ people, saying:

I have received an email yesterday from Michael Orloff and much impressed with the 'Flat Table of Sites' of Russian language Web sites for the preparation of World TRIZ-related sites Catalogs.
The present list of Russian language TRIZ sites are really nice and will make the World WTSP Catalogs useful and meaningful. The present table has been compiled by Michael Orloff with much efforts, and with some help by Nikolay Shpakovsky. We thank them much for their efforts.  ....

35 TRIZ sites written in Russian language in the world are selected and briefly introduced here.  The sites are listed in the form of 'Flat Table of Sites' for the preparation of the World WTSP Catalogs.  We can learn that there are many excellent sites written and operated by TRIZ masters which have not been known well in the world because most of them are written only in the Russian language. 

WTSP New Strategy: New Strategy of the WTSP Project: To Show World WTSP Catalogs Quickly (Toru Nakagawa & 5 Global Co-editors) (Jul. 25, 2019)

This is an excerpt of Section 4 of the preprint of our ETRIA TFC2019 paper.  It is a comprehensive description of our new strategy since the beginning of June as described in the Practice Guide , its Short Summary , WTSP Mails and Letters etc.  Our original strategy was:  Bottom-up Approach: Build Country WTSP Catalogs first with many Web sites after thorough survey. Then we build World WTSP Catalgos with selected sites. -- This puts much burden on WTSP members. Hence, WTSP Teams have not started well in almost all countries.  Our new strategy is:  Try to show the World WTSP Catalogs quickly, relying on the "20 - 80 % Principle", i.e., "Do rough but essential 20 % efforts and get 80 % results".  -- Looking at the image of our final goal in a concrete form, many people will understand the vision clearly and will join us.   This strategy is explained concretely:  Structure of World WTSP Catalogs, Japan Part of World WTSP Catalogs as an example, Practice Guide, and Plans.

 World WTSP Catalogs (Japan Part): WTSP Catalog of TRIZ-related Sites in Japan for the people in the whole world (Toru Nakagawa)  (Jul. 14, 2019))

Japan Part of the World WTSP Catalogs has been demonstrated in the new page. This posting has 3 intentions:
(1) 'The Catalog of TRIZ-related Sites in Japan' posted last year in English was the English translation of 'Japan WTSP Catalogs' for the people in Japan .  Using the WTSP criteria, all the sites are re-evaluated; ◎〇□ sites to be shown in the World WTSP Catalogs (for all the people in the world), while ◎〇□ and △ sites in the Japan WTSP Catalogs (for people in Japan).  This sort of differences in the WTSP criteria between World and Country should be recognized in every country. 
(2) The new page demonstrates the manuscripts to be prepared by WTSP Teams in every country (i.e., Flat Table of Sites (in .xlsx) and Descriptions of Sites (in .docx), and at the same time a completed WTSP Catalog as a small Web site (i.e., Index page (in .html) and Descriptions of Sites page (in .html) connected with many hyperlinks).  The final form of the World WTSP Catalog is expected to be the integration of many World WTSP Catalogs (Individual Part) coming from Country Teams and Top-down Surveys.  Flat Tables of Sites are integrated into a single Flat Table in Excel, and it is sorted/rearranged in Excel to form a suitable Index page in HTML.  The 'Descriptions of Sites' files are converted into HTML files and are simply gathered in a folder. 
(3) For Completing the World WTSP Catalogs before TFC2019, I am planning the following 2 steps .  (Step 1) Using the manuscripts submitted by Jul. 28, I am going to make a World WTSP Catalog containing the sites ◎〇 only and post it around Aug. 4.  (Step 2) Using the manuscripts submitted by Sept. 15, I am going to make the World WTSP Catalogs containing the sites ◎〇□ and post them around Sept. 30.  I wish many TRIZ colleagues in the world to contribute their WTSP manuscripts by following the WTSP Practice Guide .  The present page illustrates the manuscripts and the prototype of the completed  World WTSP Catalogs.

 Short Summary of WTSP Practice Guide:  Practice Guide to Complete the World WTSP Catalogs  (Toru Nakagawa) (Jul. 7; Jul. 14, 2019)

Short Summary is posted for the WTSP Practice Guide .  Structure of World WTSP Catalogs is shown, and the documents expected from each country as the country part of the WTSP Catalog are described along with the practical preparation process.   We coordially invite you to join this voluntary project for promoting TRIZ and related methodologies further in the world.

The final form of WTSP Catalogs has been changed from PDF (with links) to HTML (with hyperlinks). Two-step schedule for preparation is announced: WTSP Catalog of ◎○ sites (Manuscripts due: Jul. 28, 2019; Posting: Aug. 4, 2019); WTSP Catalogs of ◎○□ sites (Manuscripts due: Sept. 15, 2019; Posting: Sept. 30, 2019). (Jul. 14, 2019) 

 New WTSP page: (A6-A) Current Working Manuscripts of WTSP Catalogs  (Editor: Toru Nakagawa) (Jun. 26; Jul 6, 2019))

This page is started in place of '(A6) Publicized Outputs', for the purpose of encouraging the building, review, and revisions of the WTSP Catalogs openly.  Any  readers, TRIZ colleagues and users, are encouraged to contribute their information, suggestions, and thoughts about various TRIZ-related Web sites to be introduced in the WTSP Catalogs.  Please communicate with some nearby WTSP members or directly to the Project Leader.

  Practice Guide to Complete the World WTSP Catalogs and to Report It at ETRIA TFC2019 (Toru Nakagawa) (Jun. 10; Jun. 14, 2019)

This article is our Practice Guide for completing our World WTSP Catalogs before TFC2019 (to be held on Oct. 9-11, 2019 at Marrakech, Morocco).  It is based on the last two sections of our recently-submitted TFC2019 paper (written in black fonts), which reflects our recent discussions .  To make this an effective Practice Guide, I have added various notes, referring to existing information (in green fonts) and mentioning new and detailed information (in blue fonts).
This article has 2 important findings.  (a) I have obtained a clear and practical technical vision of World WTSP Catalogs in the form of Interactive Edition; composed of the Index file (.pdf) and many List of Sites files (.pdf), where both types of files can be built and updated easily.  See the Figure attached.
(b) Forming WTSP Teams with Country Editors in every country is most crucial for the success of WTSP.
We eagerly wish to work Together ! Connected !! with you for further proliferaion of TRIZ and related methodologies.

 Objectives of WTSP and Practical Approaches for Us: In Reply to Michael Orloff (Toru Nakagawa) (Jun. 2, 2019)

Probably, my recent articles on Internet surveys and Database System proposal give impression to M. Orloff and many TRIZ colleagues that the WTSP project is now expanding too big to follow. This misunderstanding might have come from the difference between my work for thinking about the final publication of WTSP Catalogs at the global level and the work expected for WTSP members to visit and describe individual sites at the country level. 
Thus using the 8 slides we presented at ETRIA TFC2018, I show that our aims and plans etc. are the same and even the difficulties we are facing now are essentially the same as before.  The crucial issues for us exist at the coutry level, to form a WTSP Team, to get Country Editor for coordinating the Team, and to build the WTSP Catalog in the county. Thus in this article I discuss about the practical ways of bottom-up approach for building Country WTSP Catalogs step by step.  I also show the practical process at the global level to build the World WTSP Catalogs manually without assuming the WTSP Database System now at the proposal stage.

  Proposal of the WTSP Database System for the World TRIZ-related Sites Project (WTSP) (Toru Nakagawa)   (May 24,2019)

This is a proposal to build "WTSP Database System". It accepts the description of individual Web sites in a standard format, containing the answers in the aspects of Location, Language, Role, Application phase, Application fields, Methods, and Evaluation. The key to our system is these Multiple sets of Indexing Schemes. The System can generate WTSP Indexes and WTSP Catalogs in various ways of hierarchical classification and arrangements from these aspects, as specified by the control input. It also serves as an on-line Query System using the same mechanism of hierarchical classification.  The proposal is written conceptually yet thoroughly for implementation.  See the figure of the overall structure of the System .  Once having the WTSP Database System installed, we will be able to concentrate our efforts to survey and describe good Web sites in TRIZ and relevant methodologies.

  Multiple Sets of Indexing Schemes for the WTSP DB System (Toru Nakagawa) (May 24,2019)

This page posts the definitions of Multiple Sets of Indexing Schemes for the newly proposed WTSP Database System .  Indexing Scheme means a system of categories (or answers to users’ questions) in one aspect of users’ interest.  Defining the aspects and defining the system of categories in each aspect appropriately are very important as the basis of the WTSP DB System.  All the details of these Indexing Schemes should be discussed further and revised as soon as possible.  Please send me questions, comments, and revision proposals.

  Preliminary Internet Searches (3) of TRIZ-related Sites in wider scopes in the world (Toru Nakagawa) (May 18; Jun. 23; Jul. 6, 2019)

I started the '3rd round' of surveys of TRIZ-related sites in wider scopes by using keywords different from TRIZ.  At moment, I am going to focus the sites written in English and located in the whole world.  The choice of the keywords is important and delicate.  We will need several (or many) sets of keywords for the survey, on some trial basis.  Since we are surveying in a wider scope, we have to check many more sites and select useful sites from them.  This requires us hard work in somewhat not so familiar areas. 

  Preliminary Internet Search (3A) of TRIZ-related Sites in a wider scope with the keywords Creat* Think* Method*  (Toru Nakagawa)  (May 18, 2019)

I used the Keywords: Creat*  Think*  Method*  (with the wild card *).  The Yahoo.Japan search engine interpreted the keywords much widely such as: (Create, Creative, Make, Build, etc.) AND (Think, Thinking, Thoughts, feel, believe, etc.) AND (Method, Tool, Technique, Way, etc.).  Thus the outputs are much diluted.  Evaluating the sites quickly, I obtained the results: ◎ 1 site, ○ 4 sites, □ 15 sites, △ 3 sites, and - 84 sites.  The sites are shown in the HTML page and in the .docx file .

  (3A2) of TRIZ-related Sites in a wider scope with the keywords Creative Think Method  (Toru Nakagawa)  (May 18, 2019)

The keywords: Creative Think Method.  This works well.  Among the 194 sites, I evaluated as: ◎ Most important 1 site, ○ Important 15 sites, □ World Catalog 65 sites, △ Country Catalog 31 sites, L (Listed already elsewhere) 15 sites, and - Irrelevant 56 sites.  The sites are shown in the HTML page and in the .docx file . See also the sample description of the and sites in the HTML page. 

  (3B) of TRIZ-related Sites in a wider scope with the keywords: (Creative OR innovative OR Systematic) Problem Solve (Method OR Process OR Technique)  (Toru Nakagawa)  (Jun. 23, 2019)

The main theme has been extended from 'Creative Thinking' in (3A2) to more objective one 'Creative Problem Solving' in (3B), and the result is very productive to find many useful sites. Among the 173 sites, I evaluated as ◎ Most important 10 sites (including 8 sites L alreday listed elsewhere), ○ Important 26 sites (including 7 L sites), □ World Catalog 64 sites (including 7 L sites), △ Country Catalog 32 sites (including 1 L site), and - Irrelevant 39 sites.  The sites are shown in the HTML page and in the .docx file . See also the sample description of the and sites in the HTML page. 

  (3C) of TRIZ-related Sites in a wider scope with the keywords: Innovation (Process OR Strategy OR Method OR management OR Technology)  (Toru Nakagawa)  (Jul. 6, 2019)

The main theme has been further extended to the hot and big topic of Innovation.  For putting stress on its methodological aspects, either one of the keywords Process, Strategy, Method, Management, and Technology is requested in the survey.  The survey outputs many useful Web sites, most of them are not covered with the previous survey resulats.  Among the 207 sites, I evaluated as ◎ Most important 3 sites (including 3 sites L alreday listed elsewhere), ○ Important 36 sites (including 11 L sites), □ World Catalog 78 sites (including 8 L sites), △ Country Catalog 70 sites (including 0 L site), and - Irrelevant 19 sites.  The sites are shown in the HTML page and in the .docx file . See also the sample description of the and sites in the HTML page.  Note the evaluations are tentative, and need to be reviewed by people familiar in this wider fileds.

  Preliminary Internet Searches (2) of TRIZ-related Sites in the world (Toru Nakagawa) (Mar. 18; Mar. 31; Apr. 9, 2019)

Surveys of TRIZ-related sites are carried out in a top-down approach by use of Internet Search engines.  This series is named '2nd Round Preliminary Internet Search'.  The searches are carried out for the TRIZ-related sites in the whole world written (2A) in English, (2B) in Russian, (2C) in German, (2D) in French, (2E) in Spanish/Portuguese, and also (2F) the sites in USA written in English. 

Processes of the internet search and further data handling for understanding and evaluating the sites are devised and described in detail.  Quick visit of the sites and applying the Site search (i.e., searching TRIZ-related pages inside the site) are used to understand and evaluate the sites.  Evaluation of sites in 5 levels is introduced as: ◎ Most important, ○ Important, and □ Worthy in the World WTSP Catalog; △ Worthy  in Country WTSP Catalogs; and - Irrelevant/neglected in the WTSP Catalogs. Classifying the site types with the roles of the site (owners) are also introduced.

For confirming the survey strategy, the effectiveness of the 'Base Document' (i.e., the annotated list of 'Selected 120 TRIZ Links in the world', which was compiled by Nakagawa in May 2008) has been examined.  The present situations of the TRIZ-related sites in Europe listed in 2008 have been examined, to find that nearly half of them are gone/inactive while the other half are active and hence their descriptions 10 years ago are now obsolete. Thus it is clear that we should carry out our surveys newly without trying to revise the old documents. 

Results of the surveys (2A) through (2F) are shown in detail in the HTML pages.  The sites written in non-English languages are not evaluated yet because of language difficulty for me.  Description of introductions of sites is left to be done by the collaboration of many TRIZ colleagues.   

Note:  The Data Parts of these pages are shown in a tabular form. By the ordinary 'Copy & Paste' operation of the whole table into an Excel file, you can get the Table of sites, in a form handy to edit and sort as you like. The data of sites in different pages (2A)  to (2F) may be merged easily (with some ovbious care).  (Apr. 9, 2019)

Michael Orloff used various Internet searches together with his background knowledge, and listed the URLs of 26 Selected sites operated by TRIZ profesionals, and 49 sites/pages of TRIZ users. He says: This list is not the best and last, but maybe not bad!. Posted both in HTML and in .docx .
Nikolay Shpakovsky worked on the Output of Internet search (by Nakagawa) and made a list of 36 Selected TRIZ Sites (by adding 15 new sites) and separated them from 73 other sites.  The 36 selected sites are shown in a tabular format in HTML , while all the 109 sites are shown in .docx .

 Examining the Changes in TRIZ-related Sites since 2008 (in Europe as Samples)  (Toru Nakagawa)   (Mar. 31, 2019)

Effectiveness of the annotated list of 'Selected 120 TRIZ Links in the world' (compiled by Nakagawa in May 2008) has been examined.   And we get the conclusion that the list described 10 years ago is quite obsolete and we must carry out our surveys newly without trying to revise the old documents.  See .docx

  Creativity education: CID Course for Children: Course of Creative Imagination Development (CID) based on TRIZ: Methodical Guide-Books and Children Workbooks for Three Grades (Japanese Edition) (Author: Natalia Rubina; Japanese translation: Toshio Takahara, Chiharu Fukuda, and Toru Nakagawa) (Feb. 24, 2019)

This education material is a set of 6 volumes of Guide Books for teachers and 6 volumes of Workbooks for children. It is a nice and vivid document for educating children at the 1st to 3rd grades in elementary school.  CID for children is to enhance their natural curiosity and creativity and to educate them to think with systemic understanding.  Such education is indeed challenging and need to be learned from experiences by pioneers.
We have just completed to translate the first volume of the documents into Japanese.  Both the Guide book and Workbook are downloadable in PDF files, which can be printed and bound easily in the pamphlets, just like the original Russion documents.

- [WTSP] Letters (7M-A)(7M-B)(7M-D)(7M-E): List of WTSP Members, Tasks at moment, and Invitation to WTSP (Toru Nakagawa) (Jan. 13, 2019)
To the TRIZ leaders/colleagues who are not yet WTSP Members, I sent [WTSP] Letters (7M-E) or (7M-D) for inviting them to join WTSP, and for explaining our aims, ways of work, members, references, etc.  To the Members, I sent [WTSP] Letter (7M-B) or (7M-A) for showing the list of members and invitees, and for asking them to form teams and to start the actual work of surveying and describing the introductions of the sites one by one.  These 4 types of [WTSP] Letters are posted publicly as the basis of our practice. 

- Tan Eng Hoo of Malaysia reported me of their myTRIZ activities.  They have 11,000 members and organize conferences, seminars, etc. getting involved by people coming from ASEAN countries.  And he says myTRIZ is the only national-level Web site in Malaysia.  I responded: Please introduce various Web sites (even not national representative) operated by universities, laboatories, companies, community centers, consultants, individual users, etc. for the information for people in your country (i.e., Malaysia WTSP Catalog), and then recommend selected sites for the information for people in the world (i.e., Global WTSP Catalog).  Anyway, Malaysia seems to be an excellent model of TRIZ proliferation.

  TRIZ Forum:  Letters from Readers (Dec. 2018 - Jan. 2019)   (Feb. 6, 2019). Index of Letters from Readers   (Feb. 6, 2019)

During this period, we could post 2 important Keynote Lectures presented by Prof. Denis Cavallucci (presented at Japan TRIZ Sympo. 2012) and by Dr. Valeri Tsourikov (presented at TRIZ fest2014), both in English and in Japanese translation.  I was also working for the WTSP project.

[English page   ]  Toru Nakagawa; Don Masingale (USA), Walter Hermans, Christopher K. Ahoy (USA), Val Tsourikov (Belarus), Ellen Domb (USA), Alexander Shmonov (Russia)
This page ’Letters from Readers' is for recording various communications between readers in the world and the Editor, myself.  But communcations specifically on the WTSP project are posted separatety in the page of 'WTSP Mails and Letters' starting in Jan. 2019. .
Among various short communications I received, Walter Hermans' question on 'softTRIZ' and CrePS is worth mentioning here.  He seems to learn various TRIZ Web sites and references, so I recommended two of my articles as good entrance to my many papers.. 

[Japanese page ] Toru Nakagawa; Toshio Takahara
T. Takahara has found significance in Cavallucci's IDM approach, seeing some common viewpoints with Larry Ball's 'Hierarchical TRITRI Algorithm' and with his own theory. He has contributed to the translation into Japanese of both Cavallucci and Ball's references. 

 WTSP News:  List of WTSP Members (83 Members from 31 countries) is posted in the (A2) Organization page (Toru Nakagawa)  (Jan. 13; Feb. 6; Feb. 14; Feb. 28, 2019)

List of WTSP Members is updated .  Currently 78 persons have voluntarily joined WTSP as Members.  They come from 29 countries/areas.  In each country they are trying to form a WTSP team with several members.  We are going to survey TRIZ-related sites in each country and describe introductions of them individually.  Please notice our time schedule:
      (by Dec. 31, 2018)  Formation of WTSP teams in every country
      (by Mar. 31, 2019) Completion of Country WTSP Catalogs in every country, for open reviewing inside the project; First draft of Categorized World WTSP Catalog
Such activities have just started in each country, but very slowly yet.  We wish to have many more Members in most of the countries, especially in Russia and USA.  Could you please join WTSP, to work Together ! Connected !!  (Jan. 13, 2019)

I received only 2 new Membership Application Forms since a month ago.  We are much behind the schedule.  We have to form WTSP teams in every country and to start surveying TRIZ-related sites and describe thier introductins one by one.  (Feb. 6, 2019)

   TRIZ Paper: Computational Creativity: Path to Future Civilization (Valeri Tsourikov) (Jan. 10, 2019)

Valeri Tsourikov (Chief AI architect, www.truemachina.com, Minsk, Belarus), Keynote talk at TRIZfest2014 Conference, Prague, Sept. 5, 2014; Japanese translation by Toru Nakagawa
Dr. Valeri Tsourikov started Invention Machine Project in mid 1980s in Minsk, Belarus, and after moving to Boston in early 1990s his Invention Machine Inc. built the TechOptimizer software  which fully implements knowledge bases and tools of TRIZ. Artificial Intelligence (AI) is his specialty area. He developed semantic analysis methods of natural language with the keys of SVO structure, and hence made it practical to process huge volume of patent and scientific/technical documents and output the essence of knowledge in compact and usable forms.  The software contributed much to the sensational debut of TRIZ in late 1990s in US, Europe, Japan, etc.   He also developed an epoch-making concept of 'software which assists inventions' and implemented it into a prototype ; his thoughts, however, seemed to be too early at that time.   In 2001 he left IMC, and never appeared in the TRIZ community for many years.
In 2014 he gave a Keynote lecture at MATRIZ TRIZfest conference, with the slides posted here. Last October at ETRIA TFC2018 he gave another Keynote Lecture, and I met him after 17 years of interval.   Dr. Tsourikov kindly contributed his two Keynote presentations to this Web site.   I have chosen to post his Keynote 2014 because it's more basic and easier for us to understand. "Artificial Intelligence is surely going to supercede human brains. It is natural and inevitable. AI will supercede much higher pretty soon.  AI techniques will handle not only practical and formalizable jobs (as many people say) but also creative jobs like inventions (in contrary to sayings by many) much better than human brains.   As the results of my research for these 20 years, I have already built such a prototype. " he says. Anyway please read his presentation slides posted here in English and in Japanese translation.

From the Editor:  Message for the New Year 2019 (Toru Nakagawa) (Jan. 10, 2019)

Greetings from Japan for a Happy New Year 2019!!  Wish the year be peaceful in the World, and healthy, happy, and successful for you all.
(Sorry to be late in greeting you.)  It is a tradition in Japan to send post cards for celebrating a new year.  In the Japanese page of this site I posted my New Year post card, which I sent to my friends whom I met before my TRIZ days.  Here is the card in Japanese (Figure), and its message in English. :

Happy New Year 2019 !!
I keep working for the research and proliferation of 'Methodologies of Creative Problem Solving (TRIZ/CrePS)'. This Web site "TRIZ Home Page in Japan" celebrated the 20th Anniversary last November to my thanks to you all.
I have proposed a voluntary international project 'World TRIZ Sites Project (WTSP)' and am endeavoring to build Catalogs for introducing TRIZ-related Web sites in the world. After an year of initial preparation, I have just made up my mind to complete its first Edition in October 2019, to update it completely in every 2 years, and to run the operation for 10 years, in cooperation with many TRIZ colleagues. 
Human Culture has chosen (or recognized) Liberty and Love as the two Principal Guiding Principles, but there exist intrinsic contradictions, inside each of them and between the two, which have not been resolved throughout the human history. It should be Ethics that motivates and coordinates both Liberty and Love; Ethics is the most basic Principal Guiding Principle based on the understanding that every person has the rights to pursue one's own happiness. Pursuing for the three goals together, i.e., to extend Liberty, to expand (or universalize) Love, and to deepen Ethics, is Good for individuals and for societies. Insisting and pursuing for 'Liberty alone / Love alone / Ethics alone' is NO Good. This is my understanding at the present stage. 
I wish you all your health, happiness, and success.

   TRIZ Paper: How TRIZ can contribute to a paradigm change in R&D practices? (Denis Cavallucci)   (Japanese translation: T. Takahara, H. Kosha, T. Nakagawa) (Dec. 13, 2018)

Keynote Lecture and Advanced Tutorial presented at Japan TRIZ Symposium 2012, held by Japan TRIZ Society, Sept. 6-8, 2012 at Waseda University, Tokyo.  English page: Keynote Paper , Tutorial Slides ; Japanese page: Keynote Paper , Keynote Slides .
The full set of documents presented by Prof. Cavallucci 6 years ago at Japan TRIZ Symposium 2012 are re-posted here under the permission by Japan TRIZ Society.  Especially, the full paper is posted newly in Japanese translation, with the revision by Nakagawa. 
The full paper of the Keynote Lecture is excellent.  INSA Strasbourg in France has been operating a regular graduate course at the Master and PhD levels specialized in TRIZ, as one of the few universities in the world.  Professor Cavallucci's group started with classical TRIZ, introduced OTSM while inviting Nikolai Khomenko, and then built their own IDM (Inventive Design Method) so as to handle real complex problems in industries.  There are five limitations in TRIZ for such a purpose, he says, and IDM is desigened to overcome them.  They also built the STEPS software for implementing their methodology.  The full paper seems to be his representative work describing his methodology thoroughly and systematically and guiding their further development.  We can learn much with the paper and the slides.

 [WTSP] Letters (6M)(6I):  Invitation to WTSP. WTSP pages in THPJ are updated (Nov. 21) (Toru Nakagawa)  (Feb. 6, 2019)

On Nov. 22, 2019, WTSP Letters (6M) were sent to the Members, and (6I) to Invitees for giving information of current status of WTSP as updated in the Web site "TRIZ Home Page in Japan".  Noticing the importance of recording official communications and announcements of the WTSP project, these two WTSP Letters are posted in a new page.

During this period, I gave a paper presentation on WTSP at ETRIA TFC2018 and tried to invite the participants to the WTSP members.  And after TFC2018 I sent many emails for supporting to organize WTSP teams in many countries.  However, there are few receiving emails suitable to be posted here openly.

( When I posted the Japanese page of ’Letters from Readers (Oct. - Nov., 2018)' on Nov. 21, 2018, I was so busy that I missed to post its corresponding page in English.  Here it is in a slightly simplified form.) The communication by Dr. Valeri Tsourikov is very valuable.  He comments on the importance of consolidating all web sites in one place, to let people finding info on TRIZ easier, and talks about his great challenge of generating creative solutions automatically with Artificial Intelligence.  His Keynote Paper presented at TRIZfest2014 has been posted recently in this Web site both in English and in Japanese translaton. 

 [WTSP] Letters (5M)(5I)(5C):  Information and invitation for forming WTSP teams and starting the work (Toru Nakagawa)  (Nov. 21, 2018)

WTSP Letters were sent on Nov. 14 to 3 groups of people separately, i.e., (5M1) Members, (5M2) Members to be (not yet submitting the Membership Application Form), and (5I) Invited people.  Then on Nov. 15-17, WTSP Letters (5C) were sent to the people (of the type M1, M2, and I) in each country separately for helping them to form a WTSP team and to start making the WTSP Catalog in each country.  Letters (in a generalized style) are shown in the subsequent page.

 WTSP Mails:  Quick Reports of WTSP at ETRIA TFC2018 (Toru Nakagawa) (Nov. 21, 2018)

At TFC2018, Nakagawa presented the WTSP paper and appealed the participants one by one to join WTSP.  We obtained 45 new persons who signed in the Membership Application sheet.  Emails were sent to the WTSP Members on Nov. 3 and to the new Members (to be) on Nov. 4, to report these results and urge them to start a new phase of forming WTSP teams in each country.

We have just set our concrete target as shown above.  And the time schedule for achievig the goal is shown in the (A1) Policies page .  Let's work to complete the WTSP Catalogs of individual countries and the whole world in one year from now !

Presented at TRIZ Future Conference (TFC2018), held by ETRIA and INSA Strasbourg, on Oct. 29-31, 2018 at Strasbourg, France.  Full paper (19 pages) (in HTML and PDF), Presentation slides (17 slides) (in HTML and PDF ), and Summary slides (8 slides/ 2 pages) (in HTML and PDF) .  In the Japanese page, the Summary slides are posted in Japanese translation . 

We made a presentation earlier at Japan TRIZ Symposium (Sept.13-14) with the same title.  But having a sense of crisis "Many people support the aims of WTSP, but very few actually join to work together", I prepared the slides short and clear, describing the background, aims, prototypes, working plan, difficulties and how to overcome them, etc. 

Handing out Summary slides printed on a sheet (8 slides, on both sides), I asked the TFC participants one by one for their voluntary help to WTSP.  45 people newly signed in the application to the Membership of WTSP, to our pleasure. The WTSP has nearly 70 voluntary members now, but is still very weak because all the people say veyry busy.  We need to work effectively under such a situation.  We set up our goal "Report the Completion of World WTSP Catalog (2019) at ETRIA TFC2019 in October 2019".  For this goal, we should organize WTSP teams in every country before the Christmas/New Year vacation.   

  On the 20th Anniversary of  "TRIZ Home Page in Japan":  Toru Nakagawa (Nov. 11, 2018) 

This Web site "TRIZ Home in Japan" celebrates its 20th 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, and I recently presented papers on the fundamental contradictions in Human Culture and their solution directions in 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.  Four Entrance Pages have been installed in 2012 for your easy access to articles.  Since last November I have initiated the World TRIZ Sites Project (WTSP) for building catalogs of TRIZ-related sites in the world by voluntary collaboration of many TRIZ leaders over the world.

The number of visits since November 2005 is (on Nov. 11) 237,172 (increasing by about 3,300 for the last 1 year) to the top page in Japanese and 43,275 (increasing by about 1,600) 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.

 



 TRIZ/CrePS Paper (Social problem): ‘Liberty vs Love’ and Ethics: Principal Contradiction of Human Culture and Solution Directions (Toru Nakagawa)  (Nov. 11, 2018)

Presented at ICCI2018 (International Conference on Creativity and Innovation) held by Japan Creativity Society and Kindai University ICMI on Sept. 10-12, 2018, Osaka. 
In addition to the Abstract posted earlier (Aug. 14, 2018), the full paper (in HTML  and in PDF ) and the presentation slides (in HTML  and in PDF ) are posted in English under the permission by ICCI2018.  In the Japanese page, the presentation slides (in HTML  and in PDF ) are now posted in Japanese translation, in addition to the discussion part of paper posted earlier.   The findings in the present study is summarized in a slide as:

Obtained Basic hypotheses of Principal Contradiction (Liberty vs Love) and its solution directions (Ethics):
    ・ The 1st Guiding Principle 'Liberty' is to decide and act for oneself and aims at winning in competitions.  It brings in creativity and innovation in culture and society, but also ruling and conservatism by the winners.
    ・ The 2nd Guiding Principle 'Love' is to love people, serve for them, and aims at happiness of the members.  It brings in reformation, but also control and conservatism for protecting all the members.
    ・ The 0th Guiding Principle 'Ethics' is most basic, and inside human heart shows the directions towards Good.  Fundamental Human Rights, saying 'everybody has the rights to pursue happiness', forms the core of Ethics.
    ・ 'Liberty vs Love' is the Principal Contradiction of Human Culture, which has never been solved yet throughout the human history.
    ・  Keys to solve the Contradiction are Ethics, capable to motivate and coordinate both Liberty and Love.
    ・  The origin of Ethics is the inherent (i.e., DNA built-in) capability of heart to judge what is Good ('Conscience').

Confirmed the significance of present hypotheses in comparison with Ethics references:
  ・ Hypothesis (a)  Principal Contradiction = Liberty vs. Love :   Novel? (yes (?)), Valid? (yes),  Effective? (yes)
  ・ Hypothesis (b) Keys to solving the Contradiction = Ethics :    Novel? (yes (?)), Valid? (yes),  Effective? (yes)
   ・ Hypothesis (c) Origin of Ethics = Inherent capability 'Conscience' :    Novel? (yes (?)), Valid? (yes),  Effective? (yes)
   ・ Hypothesis (d) Good = Guidance of Liberty, Love, and Ethics, together :    Novel? (yes), Valid? (yes),  Effective? (yes)

  Forum: Visiting Mr. Yasuyuki Takaguchi, ex-Chief Priest, of Isshinji Temple in Osaka  (Oct. 19, 2018)

On Sept. 9 and 10, I visited Mr. Yasuyuki Takaguchi, ex-Chief Priest, of Isshinji Temple in Osaka.  He is one of my best friends studying together at Koyo Gakuin, Junior and Senior High School, in Nishinomiya City, Hyogo Prefecture, playing (soft) tennis in a pair.  He studied Architecture at Kyoto University, and later happened to become Chief Priest of Isshinji Temple (Jodo Shu in Budhism), and worked as Professor at Nara Women University and operated an office as the owner Architect, all at the same time.

Since he and I were working in different fields and living in different areas in Japan, we did not have so much chances of talking deeply even though we knew the hard working of each other.  In the visit this time, I re-realized his personality and great achievements. So I asked him to contribute a series of articles on his thoughts, activities, and achievements, to TRIZ Home Page in Japan. 

Please take a look at the photo attached here. It shows the inside of a hall 'Sanzen-Butsu-Do', designed and built by Rev. Takaguchi in 2002.  He writes: "This Hall is built just outside of the traditional Isshinji campus, facing to a public street and is open everyday from 9:00 to 16:00 for everybody freely, symbolizing an Open Temple. You may encounter with (or be embraced by) Amida Butsu (in the center) and Kannon Bosatsu and Seshi Bosatsu, who have come to save you over the peaks of Himalayas.  I wanted to build a Budhist Hall with a brilliant chancel and with sky lights coming down through a high ceiling window.  For designing such a Hall, I visited Budhist halls in India, Islamic halls in Turkey, and Byzantine style Christian church in Venice, etc. and extracted the atmosphere common to them."  When I stepped in, I gasped in wonder, and while sitting quietly alone, I felt myself being purified.

The Update Announcements of this home page are recorded. During this period, appeals for working together in the WTSP project are main activities.  Emails were sent to many TRIZ leaders in various countires, and responses were received. But they are not disclosed here.  Nakagawa posted his papers on the "Principal Contradiction of Human Culture: 'Liberty vs Love' Contradiction and Ethics" presented at (2C) ETRIA TFC2107, (2D) TRIZ Home Page in Japan, and (3A) ICCI2018.

  Basic Theory: "A Working Research Note on Philosophy (2018): A Note on the Principle of Way of Life of Homo Sapiens Based on Contradiction Model and Radical Enumerable Thinking " (Toshio Takahara) (Aug. 30; Sept. 1; Oct. 10, 2018)

Contributed to TRIZ Home Page in Japan on Apr. 12, 2018; Revised on Jun. 13, 2018; Posted on Aug. 30, 2018.  Further revised on Sept. 16, 2018 and Posted on Oct. 10, 2018.
This is an up-to-date working research note written by Toshio Takahara in Japanese for the purpose of describing his system of theories as closely as possible.  Because of its big volume (over 80 pages), it is published here in four parts besides a top page.  Abstract written by the author in English (in 5 pages) is posted in HTML  and in PDF
Concept of Radical Enumerable Thinking (RET) and Contradictions (especially the Contradiction of Unity) are his main methods for investigation.  His up-to-date understanding (in Mar. 2018) of these concepts are described in Part 1 and Part 2.  Then in Part 3 he writes, Objectization (= analysis, seeing objectively, individualization, liberty, criticism, etc.) and Unification (= synthesis, taking subjectively, integration, love, modesty, etc.) should be used repeatedly, hierarchically, with nesting, etc. for the purpose of Resolution of Differences (i.e., problem solving, task achieving, etc.).  And it forms the basis of our ways of living, he says.  He also writes often about the importance of understanding the overview of human history (and its significance), such as the significance of the beginning of barter, and of agricultural revolution and industrial revolution as energy revolutions.  In its Part 4, he writes a preparatory discussion on post-capitalism.  The author describes his various insights clearly.

  Basic Theory: "World View, Attitude and Logic of Life to Survive in the Universe " (Toshio Takahara) (Aug. 30; Oct. 10, 2018)

Presented at FIT 2017. On posting the 4th Collection of Papers written by Toshio Takahara (2016 - 2018), I feel it necessary to post this paper and its presentation slides in English, because his voluminous works are mostly written in Japanese only.  The phrase 'to survive in the universe' is somewhat peculiar, but it intends to eliminate various factors 'happened to be specific to the human kind on the Earth' and to extract really essencial factors in the desirable ways of living and ways of thinking for humans, I suppose.

"TRIZ Home Page in Japan" has been publishing all the papers presented by Toshio Takahara since 2003, resulting 47 papers in total for these 15 years.  This 4th Collection covers all the 11 papers published by the author from 2016 to 2018 in relation to TRIZ in a wider sense.  Most of them are written in Japanese and some in English.  All the documents are posted here in PDF with links, and some of them are posted in HTML pages as well.   The author is trying to think over everything radically, generally, and systematically for building his original system of theories.  Thus he defines/re-defines various concepts and terms, which make his theory not easy to understand for readers at first.  For getting introduced, you may read the introductions (or Editor's note by Nakagawa) to the the Collection (1)(2003-2007) , Collection (2)(2008-2012) , and Collection (3)(2013-2015) of Takahara's Papers. 

In English pages, the paper presented at FIT2016 was published in Nov. 2016, and another presented at FIT2017 is now posted separately. The most important document in the 4th Collection is the Working Research Note (2018) posted now in 4 parts in Japanese , and its abstract written by the author is posted in English .   

 Forum: Sofware: Fuda-Memo is Open for Public Use: A Simplififed Fuda-Yose Software without using Excel (Akihiro Katahira ('Daiichi Kousha' ))  (Aug. 14, 2018)

The author is a unique thinker in creative problem solving (see (Jan. 18, 2015)) and the developer of Fuda-Yose Tool, which Nakagawa used much for Visual Thinking on social problems (see (Nov. 25, 2016)).  He has just developed Fuda-Memo software and introduces it in this home page.  It is another simple, nice, and useful software for Visual Thinking.  English version is not ready yet.

 TRIZ/CrePS Paper (Social problem): ‘Liberty vs Love’ and Ethics: Principal Contradiction of Human Culture and Solution Directions (Toru Nakagawa)   (Aug. 14, 2018)

Paper to be presented at ICCI2018 (International Conference on Creativity and Innovation) to be held by Japan Creativity Society on Sept. 10-12, 2018, Osaka.  Only Abstract is posted in English page (full paper will be after the Conference). 
The main purpose of this paper is (after describing the Basic Hypotheses) to discuss on 'Implications of the present Hypotheses in Comparison with the conventional/standard theories of Ethics and Philosophy'.  The discussion section has subsections: 7.1 What is the real root of the directions of Ethics ?; 7.2 Nature of Ethical Principles/Rules; 7.3 Comments on modern Ethics, especially on Utilitarianism; 7.4 Liberty vs Love Contradiction in place of Sidgwick’s Dualism of Practical Reasoning; 7.5 Discussion on Rawls’ “Principle of Justice”; 7.6 Liberty, Equity, and Fraternity; 7.7 Concepts of Good and Happiness in the Present Study.  Having studied several books in Ethics closely in Japanese, I now have confirmed my understanding that the Basic Hypotheses postulated in the present study are quite different from vaious preceeding works in reference and provide with new aspects and theory of significant importance.  In the Japanese page, Abstract, Discussions, and Conclusion are posted in Japanese translation

 WTSP Appeal:  An Appeal for Building Catalogs of TRIZ-related Sites in the World (WTSP Global Co-editors) (Jun. 25, 2018) 

WTSP Global Co-editors: Toru Nakagawa (Japan), Darrell Mann (UK), Michael Orloff (Germany), Simon Dewulf (Australia), Simon Litvin (USA), and Valeri Souchkov (Netherlands), Jun. 25, 2018

While the activities and accumulated knowledge of TRIZ and relavant methodologies become larger and larger, Internet search for them comes more difficult because of so much noise. In order to solve such a difficulty, we propose to build Catalogs of TRIZ-related Web Sites in the world. We had a prototype in 2008 and have recently demonstrated WTSP Catalog of TRIZ-related Sites in Japan . On the basis of these experiences, we are going to form a WTSP team in every country and build WTSP Catalog of each country and then of the World.  Why don't you join WTSP ? Could you please post this Appeal in your own Web site or forward it to your colleagues, as a sign of your support for the WTSP project?

  TRIZ Forum:  Memorial of Mr. Masatoshi Hotta (Toru Nakagawa, Ellen Domb)   (Jun. 25, 2018; Latest update: Jun. 26, 2018)

Mr. Masatoshi Hotta, the former Managing Director of Japan TRIZ Society, has passed away on June 8, 2018.
In 1997, leading a department in Mitsubishi Research Institute (MRI), he started to introduce TRIZ into Japan in contract with Invention Machine Corp. He organized users group and users Consortium, and held study meetings every month and completed the Japanese Edition of IM TechOptimizer software, thus contributed much to the dissemination of TRIZ to industries in Japan. He was also involved actively in organizing and managing Japan TRIZ CB and NPO Japan TRIZ Society, serving as the Managing Director. At the end of 2012 he quitted his consulting firm SKI and resigned from management of JTS.  We remember him with his strengths in organization and practices and his warm heart of accepting people.  In memory of Mr. Masatoshi Hotta we have a memorial page here.  Please send us information of him and your messages for him.

 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 (D) (Toru Nakagawa)   (Jun. 25, 2018) (Jun. 25; Aug. 14, 2018)

Extended paper in Japanese (D) published in "TRIZ Home Page in Japan", Jun. 25, 2018.
 I extended the paper (A) presented in the Proceedings of Japan Creativity Society Conf. 2017 by adding much discussions, and submitted it to the Journal of JCS on Sept. 15, 2017.  But I received a rejection reply on Jan. 10, 2018, mainly because of not enough reference to preceding works on Ethics.  I revised the paper further on Jan. 14 and Feb. 27, 2018, but the review process was not opened again. ---- Since presenting my basic hypotheses thoroughly is important at this stage, I think, I am publishing the Extended Paper (D) here in "TRIZ Home Page in Japan" in the Japanese page .  English translation is not ready, but the headings of the Discussion section are shown in the brief note in English . (Jun. 25, 2018)

Full paper in English translation has been posted, in HTML and in PDF (Aug. 14, 2018). Its Discussion section has following sub-sections: 6.1 Contributions of the Creative Problem Solving Methodology (TRIZ/CrePS); 6.2 Verifications of problem situations, relevant references, and hypothesis setting; 6.3 Structure and significance of the Basic Hypotheses; 6.4 Possibility of Common Basis of Ethics in Human Culture; 6.5 Significance and influences of the First Principle Liberty: Reformism and conservatism; 6.6 Significance, influences, and limitations of the Second Guiding Principle Love: Reformism and conservatism; 6.7 Social roles of the 0th Guiding Principle Ethics; 6.8 Factors which make the Principal Contradiction of Human Culture 'Liberty vs Love' even more difficult to solve.
