  Forum:   Visual Thinking with 'Fuda-Yose' (3) - Visualizing the logic of Sickafus' Paper 'Subconscious Problem Solving Using Hazy Heuristics', (Akihiro Katahira, Toru Nakagawa)  (Aug. 25, 2015) 

Katahira has demonstrated to visualize the logic of Ed Sickafus' recent paper (in the Japanese version) with his Fuda-Yose (or Visual Thinking) method.  All the sentences of the paper are made into labels (or Fuda) and their logical relationships are shown in 'Fuda-Yose' diagrams section by section.  The diagrams are shown in PDF for the whole paper, and in HTML especially for the Abstract. 
Nakagawa, reviewing them, thought that for clarifying the logic of a compact document like the Abstract we should decompose some sentences further into their logical units.  So I applied the Fuda-Yose method to the Abstract.  The visualization was actually done in 4 steps; the diagrams are posted in HTML, in PDF, and in the original Excel file.  This example has demonstrated the merit and easiness of Visual Thinking.  (English version of Nakagawa's diagrams will be posted later.)

  USIT Paper Q&A:   Q&A on USIT and the OAF diagram (in relation to "Subconscious Problem Solving Using Hazy Heuristics" by Ed Sickafus) (Q: Toru Nakagawa, A: Ed. Sickafus (Aug. 25, 2015) 

This page records the fifteen email communications carried out last July in relation to Ed Sickafus' paper .  In particular, on my request, Dr. Sickafus kindly wrote a 4-page introductory article on the OAF diagram in USIT: 
    "Unification of USIT to One Graphic (OAF) Heuristics", Ed Sickafus, Jul. 2, 2015   PDF
He explains the definition and usage of the OAF diagram concisely and describes his research motivation towards fundamental principles in problem solving thinking. 
BTW, the start of SIT (Structured Inventive Thinking, later renamed as USIT) in Ford was revealed to be 1985 instead of 1995; the year shown in his USIT Textbook (1997) and in his USIT paper (1999) was found to be a typo.  USIT actually started earlier by 10 yeras.  

  USIT/CrePS paper:   Subconscious Problem Solving Using Hazy Heuristics (Ed Sickafus (Ntelleck, USA) (Aug. 25, 2015) ; Japanese translation: Toshio Takahara, Hideaki Kosha, Toru Nakagawa)  (Jul. 29, 2015);

This is a Keynote lecture given by Dr. Ed Sickafus (the original developer of USIT) at ICSI 2014, on Jul. 16-18, 2014.  He has shifted his focus to the research of the activities of our brains to get creative solutions and utilizing them effectively. In 2006 he discussed about the relationships between the logical thinking in the left brain and the image handling in the right brain and how to use them in collaboration.  In the present paper (2014), his study has extended further: "The 'Ah-ha!' ideas always come out of the subconscious. Invention is not done by the conscious, but done by the subconscious", Sickafus says. Thus he recognizes the importance of handing on the information appropriately to the subconscious.  He recommends to consider at the conscious level in the purposely-vague (or generalized) terms and images so as to enrich the subconscious ideation.  The author called the method "Hazy Heuristics". 
We have been developing the problem solving methods in the direction of making them structured and logical, i.e. 'Structured Problem Solving' methods.  Its purpose is to communicate about the methods among people and to build and educate the culture.   Once we have mastered such a method thoroughly, we as an individual may (and should better) use subconscious thinking more actively as the shortcuts in the problem solving process, he recommends. -- This may be the position of super-experts, as in the old saying "Enter the Form, and Leave the Form".

  Forum: From Readers:   Visual Thinking with 'Fuda-Yose' (2) - Converting a (short) document into labels and make 'Fuda-Yose' diagrams for Visual Thinking (Toru Nakagawa, Akihiro Katahira)  (Jul. 29, 2015)  -- No English page yet.

As a basis of usig Visual Thinking, Nakagawa asked Katahira to show the method of converting a (short) document into labels automatically and making 'Fuda-Yose diagrams.  Katahira demonstrated the method by using Nakagawa's request message.  He has made a detailed record of the conversion and drawing, in the 'Fuda-Yose' Excel sheets.  The final 'Fuda-Yose' diagram (click the figure at right) clearly shows the intentions of Nakagawa's request and corresponding answers by Katahira.

  Forum: From Readers:   Visual Thinking with 'Fuda-Yose' (1) - Example of Burning Suicide in Shinkansen Case (Akihiro Katahira, Toru Nakagawa)  (Jul. 7, 2015; Jul. 8; Jul. 19, 2015)  -- No English page

Visual Thinking method and its tool 'Fuda-Yose' were developed by Akihoro Katahira and introduced in this site on Jan. 18, 2015.  For showing its usefulness, I asked him to show examples of usage on various themes.  The shocking case that a 71 yrs-old man commited suicide by burning himself on a Shinkansen train on Jun. 30, 2015 was used as an example.  The old man's mental and social situations are described with the hope of reflecting the problems in the society in Japan.

  CrePS/TRIZ/USIT Documents:   USIT Process Documents (Index): USIT: A Concise Process of Creative Problem Solving in the 'Six-Box Scheme' (Toru Nakagawa (OGU))  (May 25, 2015) (Jun. 26, 2015)

This is the index page of the documents related to USIT and belongs to the document system of CrePS. This page has the indexes of the following 4 items:.
(A) USIT Manual:   
(B) USIT Case Studies: 
(C) USIT Operators:  Links to the pages of simple/full/extended versions of USIT Operators, Cross Indexes to USIT Operators => TRIZ tools and TRIZ tools => USIT Operaotrs.

  CrePS/TRIZ/USIT Documents:   A Collection of USIT Case Studies: USIT: A Concise Process of Creative Problem Solving in the 'Six-Box Scheme' (Toru Nakagawa (OGU))   (May 25, 2015) (Jun. 26, 2015)

A number of case studies published so far in different places are collected here.  Individual case studies are described in full extent in a consistent format according to the USIT Manual .   Pleae note that several case studies originally carried out with some other methods than USIT (e.g., TRIZ and others) are also described in the 'Six-Box Scheme' and are shown here as 'USIT case studies'. In this Index page, the case studies are listed in a table.  Each case study is shown individually in an HTML page containing four slides (3 introduction slides and 1 overview summary slide in the 'Six-Box Scheme') and in a PDF file of the whole set of slides. 

   USIT Case Study 1. How to fix a string shorter than the needle (Toru Nakagawa (OGU)), (May 25, 2015) (Jun. 26, 2015)

This Case Study is originally based on Tsubasa Shimoda's Thesis at OGU (2006) and revised further by Nakagawa.  For a familiar, everyday-life problem, the USIT thinking process from the problem definition to the solution construction is explained well.  Even children can understand how to think for this problem.

 

    USIT Case Study 2. How to prevent a staple from being crashed (Toru Nakagawa (OGU)), (May 25, 2015) (Jun. 26, 2015)

This Case Study is originally based on Kazuaki Kamiya's Thesis at OGU (2004) and is further revised by Nakagawa.  In binding sheets of papers with a stapler, the staple may be crashed in case of 30 or more sheets.  We wanted to improve the stapler so as to be able to bind some more sheets.  Initailly we suspected that the looseness around the axle was the cause of weakness.  In the middle of some experiment, we met an unexpected phenomenon and found the root cause of the problem.  For solving the problem we used Altshuller's Smart Little People's Modeling (SLP).  Even children can understand and enjoy this case study.  

 

   USIT Case Study 3. Saving Water for a Toilet System (Toru Nakagawa (OGU)), (May 25, 2015) (Jun. 26, 2015)

Source Ref.  Hong Suk Lee and Kyeong-Won Lee (Korea), The TRIZ Journal (Nov. 2003)
This Cae Study has solved a familiar, widely known problem 'how to save the water consumption for flushing in a toilet system'. The authors applied the concept of Physical Contradiction of TRIZ to this problem and solved it excellently.  Once they show how to define the problem and how to handle it, even school children would start suggesting ideas just like the ones in this Case Study.  By describing this Case Study in the 'Six-Box Scheme' of USIT, we can easily follow its thinking process. 

 

   USIT Case Study 4. Picture Hanging Kit Problem (Toru Nakagawa (OGU))(May 25, 2015) (Jun. 26, 2015)

This case was originally described by Dr. Ed Sickafus in his USIT Textbook (1995). It has been used, revised, and extended by Toru Nakagawa as a standard USIT case study along with the development of USIT itself. A standard USIT Case Study on a familiar problem, easy to understand for everybody and yet deep in thoughts.

 

   USIT Case Study 5. Increase the Foam Ratio of Porous Polymer Sheet (Toru Nakagawa (OGU)) (May 25, 2015) (Jun. 26, 2015)

This Case Study was originally made by Toru Nakagawa at the 3-day USIT Training Seminar conducted by Dr. Ed Sickafus in Mar. 1999.  It used the Particles Method, an extension of Altshuller's Smart Little People's Modeling (SLP), effectively in solving the problem. In the description of the present Case Study, I inserted the Atttribute and Functional Analyses, which were skipped in the original case study, for the purpose to illustrate the USIT process fullly.  A real problem in the field of chemical engineering is solved with the Particles Method.

 

  CrePS/TRIZ/USIT Documents:   USIT Manual: USIT: A Concise Process of Creative Problem Solving in the 'Six-Box Scheme' (Toru Nakagawa (OGU))  (May 25, 2015) (Jun. 26, 2015)

USIT ('Unified Structured Inventive Thinking') was originally developed by Dr. Ed Sickafus (1995) as a concise and consistent problem solving process and has been extended further in Japan by integrating and unifying various TRIZ methods into USIT.  By recognizing the Six-Box Scheme (of USIT) as a new paradigm of creative problem solving, USIT is now established as a concise overall process for the real practice of the General Methodology of Creative Problem Solving (CrePS), which can include/unify TRIZ, USIT, and many other creative problem solving methods. 
Manual of the USIT process has been described in the form of 31 slides along its steps.  The USIT process is now fully described by use of the consistent demonstration of a case study and instructions and remarks on the USIT concepts and its thinking process.  Examples of USIT usage in the 'Collection of USIT Case Studies' are described along the steps of the 'USIT Manual so that you can understand USIT fully in its variety of usage.  The Manual is posted both in HTML (with images) and in PDF .

 TRIZ News:  The TRIZ Journal has been restarted on Jun. 11, 2015 by BMGI.    (Jun. 19, 2015)

  TRIZ Paper: Fundamental Theory:  A Note on a Method and Granularity in the Structure of the World (Toshio Takahara)  (Apr. 12, 2015)

An 8-page paper presented at FIT2013 on Sept. 4, 2013.  Mr. Takahara's life-work theme is "To understand the world in a consistent manner, to realize the real basis of our human ways of living, and to establish a general and logical methodology for such a study."  As the basis of his logic, he builds the concepts of 'existing things' and their relationships, and also the ways of describing the whole world, which contains technologies, institutions, and persons.  For such a description, he finds the necessity of 'radical enumerative thinking' (i.e., a clearer extension of 'systematic thinking') and expressions of contradictions (i.e., a clear extension of 'problems'). He also extends the logics of dialectics in a much wider meaning.  Then he considers the basis of person's recognitions and actions and derives how the person decides them, with a range of consideration (i.e. granularity) and with a logic for solution (i.e., a thinking method). He discusses further basis of the person, i.e., the person's attitudes.  The width and depth, and clarity, of the author's consideration is indeed astonishing.

 TRIZ/USIT/CrePS Talk:  Methodology of Creative Problem Solving: TRIZ and Its Extension ~ Scientific Methods for Innovation ~ (Toru Nakagawa)  (Apr. 12, 2015)

The 57 slides were given in a lecture for 90 minutes at Graduate School of Medical Science, Tottori University, on Jan. 20, 2015.   I first describe that the basic Four-Box Scheme of Abstraction which is generally assumed in the current science and technology has a limitation and that many conventional 'Creativity methods' address with different partial aspects without having a sound overall view.  As new scientific approaches to inventive thinking, I explain TRIZ first and then USIT.  On the basis of them, the Six-Box Scheme was newly formulated as the paradigm for 'General Methodology of Creative Problem Solving' (CrePS).  These four stages of development of the methodology of creative problem solving reflect my own understanding for these 18 years.  Slides in Japanese  and also in English translation  .

 TRIZ Paper: Social application:  Methods and Examples of Applying the Business Management Related Evolution Trend Proposed by Darrell L. Mann – Translating the Evolution Trends from the World of TRIZ into the Daily Business and Management – (Hisataka Izawa, Ikuo Yoshizawa, et al.(Business and Management TRIZ Research Subcommittee, JTS))  (Mar. 27, 2015)

Presented at Japan TRIZ Symposium 2014.  The 6-membered B&M Study Group reported last year how to generate 'hit products/services' and found the tool of 'Trends of evolution (TE)' effective.  So they tried to make it more useful:
(1) They have made a booklet in Japanese for introducing the Trends of evolution in Darrell Mann's book ("HOSI for B&M").
(2) They have clarified the relationships of TE with several other methods often used in the B&M fields: they include: Nonaka's SECI model, 4 viewpoints in the Balance-score cards, and SWOT.
(3) They made a case study of applying TE: To transfer the technologies of some abandoned business for starting a new business model of servicing the technologies. They have found the examination of 3C (i.e. Customers, Company, Competitors) with respect to the 32 TE very useful.
In Japanese, the full descriptions of the extended abstract and the presentation slides are shown in HTML .  In English, the presentation slides in PDF is accessible through a link to the JTS site (English translation by JTS).

 TRIZ Paper: Social application:  Proposal of an Easy Value Evaluation Method by Means of TRIZ - Taking the Proposal for a New Life Style of the Elderly People as an Example - (Part 1) (Kimihiko Hasegawa, et al. (IP Creation Research Subcommittee, JTS)), (Mar. 27, 2015)

Presented at Japan TRIZ Symposium 2014. After having completied a multiple-year project, the 8-membered IP Creation Study Group discussed freely about what they should work on next and decided to work on this topic. They decided 'The aged and their relevant people live a happy life' as the top purpose (or vision) and 'The aged people solve the problems of their own and others' as the target (or goal).   In more concrete words, they recognize the problem 'The researchers and engineers around their retirement age want to live a life with some good motivation', and wish to have solutions towards 'For achieving their own visions, the aged people solve their own problems as well as others' problems'.  -- This is an important topic for many aged engineers, including many TRIZ practitioners, and for the whole society in Japan.

 TRIZ Paper: Industrial application:  One Method for Expanding TRIZ Application -- Applying TRIZ to Products that TRIZ can Hardly be Applied to -- (Yoshiharu Isaka (IDEA))  (Mar. 27, 2015)

Presented last September at Japan TRIZ Symposium 2014.  In the areas of 'Utility engines' for example, some standard products have been delivered for decades without much change, because of no change in the requirements for basic usage as the power supply in the working machines for agriculture, forestry, etc. Isn't there any room for applying TRIZ?  The key is to find the 'sales points' which can convince the target users, i.e., the person in charge of selecting the engine in the working machine manufacturer. Thus one should think of various functions and features as the 'sales points' by using some idea generation methods. This is the 'Theme definition' stage in the problem solving process.  Then TRIZ will help to generate some methods for realizing the functions/features. -- This is an unfancy but important proposition.
Presentation slides are posted in HTML in Japanese ; those in English can be referred via a link to the Japan TRIZ Society site (English translation by JTS).

 TRIZ Paper: Industrial application:  How to Lead Beginners to TRIZ at the Place of Practices (Shigeru Hisanaga (DENSO))  (Mar. 27, 2015)

Presented last September at Japan TRIZ Symposium(see my Personal Report ) and obtained the 'Best presentation for me' Award as a result of participants voting. 
DENSO introduced TRIZ since 10 years ago (See ). The in-house TRIZ promoters have guided the projects of applicants, composed mostly by TRIZ-novices.   A key to success is realized to adopt the approach and tools which fit well with the needs and intentions of such TRIZ beginners. The author reviewed their 250 projects and characterized them with 3 types of needs (i.e., Want many ideas, Want a good solution, and Want to reconsider from the root) and with 2 types of intentions (i.e., Out of vs. Within the present constraints).   For each category of 3x2, the authors examined the TRIZ tools applied, and have summarized the TRIZ tools recommendable in each of the 3x2 categories of beginners' needs and intentions. -- This is a nice presentation with deep insights.  The author makes a concluding remark saying: "The success of TRIZ practice depends not only on the technical results but also on the participants' satisfaction. And hence, coaching is more effective than consulting."
Presentation slides are posted in HTML and in PDF , where English translation was recently brushed up by Nakagawa.

 Forum: Earthquake Prediction Research:  Up-to-Date Report on the Early Detection of Omens of Anomalies in Monitoring Power Plant Equipment (Anomalous phenomena detected just before earthquakes) (Takumi Yoshioka (Mado-Planning), Hiroaki Kawai (Hokkaido Inst. of Tech.)) (Mar. 7; Mar. 9, 2015)

Presented at a symposium of Japan Society of Mechanical Engineers (JSME) in Jun. 2010. The authors developed a software system for monitoring the operation of electric power generators in thermal and nuclear power plants.  In such data, they have found effects of earthquakes vividly.  The data monitored every minute show the effect of instantaneous jumping of the generator due to the S-wave of an earthquake, and after the quake the data show unstable increase of wattless currents due to some off-alignment of the generator axes.   In addition, since 30 minutes before the earthquake there appeared anomalous behavior in the data, just like the generator is roaring.   It is not caused by earthquake vibration but by some electromagnetic effect.  This paper clearly expresses the possibility of predicting an earthquake.  English translation of the full text is not ready.

 Forum: Earthquake Prediction Research: Introduction to the Research of Short-term (or Just-before) Prediction of Earthquakes by Use of Electromagnetic Phenomena: Especially Works by Professor Takumi Yoshioka (Hokkaido Univ. of Science) (Editor: Toru Nakagawa) (Mar. 7; Mar. 9; Mar. 27, 2015)

Even though somewhat exceptional for the present site, I am going to start the Forum for introducing researches on earthquake prediction by posting various papers and articles. My intentions are:
(a) Short-term (or just-before) prediction of earthquakes is eagerly desired.  Seismological Society of Japan (SSJ) and Japanese government, however, state that short-term prediction of earthquakes is (almost) impossible and make no significant efforts for research in such a direction.
(b) SSJ regards it impossible, because it uses mechanical aspects (e.g., position, displacement, stress, vibration, etc.) as the keys. If so, we should better try to use different types of signals, especially electromagnetic signals, as TRIZ suggests.
(c) The electromagnetic aspects of earthquakes are not yet well known, and researches in such directions are often criticized premature or even as a fake.   However, we should make efforts in multiple aspects in parallel, e.g., discoveries of new phenomena, inventions of methods for detecting and observing new phenomena, revealing the mechanisms of the new phenomena, inventions of extracting and utilizing useful information from the new phenomena, etc., so as to stimulate one another.
(d) Last year, Earthquake Prediction Society of Japan (EPSJ) was established for promoting the research of short-term earthquake prediction especially putting stress on electromagnetic aspects.
(e) I recently learned Professor Takumi Yoshioka's work where some electromagnetic signals are detected with online monitoring system of electric power generators.  Since I think it hopeful and significant, I wish to support the promotion of its examination and further development.
(f)  This Index page of the Forum will show indexes of articles posted in the present site, references, and discussions, etc.  [Index to references has been enhanced in the Japanese page. (Mar. 27, 2015)]

 TRIZ Paper: Industrial application:  Development of a Spinning Top by TRIZ & TM & Simulation -- Challenge at All-Japan Koma Taisen -- (Tomohiko Katagiri (IDEA), SWCN)  (Mar. 7, 2015)

This paper was presented last September at Japan TRIZ Symposium (see my Personal Report ) and obtaind the 'Best presentation for me' Award as a result of participants voting. 
'All-Japan Manufacturing Industry Koma Taisen (Spintop battles)' was first held in Feb. 2012 and second in Feb. 2013.   The koma (or spintop) must be smaller than 20 mm in diameter and be turned by fingers without using any tool.   There is no limit in the weight, length, shape, materials, etc.   The battle between 2 komas is performed on a slightly concave ring. The koma spinning longer on the ring wins the game, and the koma winning the game twice in a row win the match. See the battles and komas in the Koma Taisen site
The presentation slides explain the processes of considering various contradictions in the design and examining different design prototypes by use of Taguchi method and simulations.  The SWCN's koma (named 'cat's punch') was extraordinary in its shape; just after turning, the koma opens its 3 arms for hitting out the competitor, and it won the second place at the Second All-Japan Koma Taisen.

 TRIZ Paper:  Finding the needs of customer by the SN Matrix and TRIZ process -- The functional approach for connecting methods and 7 solutions -- (Takashi Ogata, Kazuhiro Fujikawa, Hiroyuki Tsuchiya (OLYMPUS Corp.))  (Jan. 18, 2015)

Presented at 10th Japan TRIZ Symposium 2014 and won the 'Best Presentation for Me' Awards by the participants voting.  The authors pursue for the methods of linking their technological seeds (S) with their customers needs (N); they want to provide new products/services of attractive quality and to reveal some hidden needs of customers. For such a purpose they have developed a scheme of describing their aims and means consistently in terms of 'functionality'.  For each of the functions, the authors clarify their goal/current levels of realizing the function, competitors' technology (contents and their levels), customers' requirements, and priority, and write them down in a tabular form named as 'SN Matrix'. The SN Matrix is consistently applicable in their 7 categories of problem solving processes (or 'solutions'). -- This is an excellent presentation having experiences of real applications and theoretical framework together.  Extended Abstract in HTML and in PDF and Presentation slides in HTML images.  The Japanese page is composed in a similar way. 

 From the Editor:  Message for the New Year 2015 (Toru Nakagawa (OGU))  (Jan. 8, 2015)

Greetings from Japan for a Happy New Year 2015!!  Wish the year be healthy, happy, and successful for you all and peaceful in the World. I am posting the New Year card in Japanese which I sent to many Japanese friends whom I got acquainted before my TRIZ days. I am much concerned about the current situations of Japanese society.  Prime Minister Shinzo Abe is driving Japan in the wrong direction.  Democracy in Japan is not working well unfortunately.  There are many big and complex issues to be addressed in relation to lives of people. -- In such a situation, I should do my best what I can; i.e., to establish the General methodology of  creative problem solving (CrePS) and to spread it widely.  I have written down several tasks and plans for the new year 2015.  I wish to work for them in collaboration you.  Best wishes!

 TRIZ Forum: Letters from Readers:  Introduction to A New Publication: "TRIZ 40 Principles" by Yoshinori Takagi (Yoshinori Takagi; Toru Nakagawa)  (Jan. 8, 2015)

The present page introduces to an excellent new publication  in Japanese, "TRIZ 40 Principles" by Yoshinori Takagi, published by Discover 21, Inc., Tokyo, on Aug. 30, 2014.  The book is very well organized in the contents, in the grouping of Principles, in the descriptions of individual Principles, and in illustrating application examples of the Principle, etc.  It is quite reasonable that the book has been one of the best sellers in the Engineering/Patents & Invention genre in Amazon.co.jp.  Congratulations!!  Unfortunately, however, in the belt and in the Preface of the book, the descriptions look too much journalistic/sensational, used to be typical in late 1990s in Japan, and contain several misleading catch copies in relation to the TRIZ history in the former USSR.  Nakagawa sent a comment to Mr. Takagi on such misleading catch copies for the purpose of preventing them from being spread to readers new to TRIZ.  (Full description in Japanese, but shorter in English.)

 TRIZ Paper:  SUGOROKU of TRIZ Inventive Principles ~ 40 Principle Symbols Arranged on 9 Windows ~ (Yoshinori Takagi)  (Jan. 8, 2015)

This paper was presented at 10th TRIZ Symposium in Japan, Sept. 11-12, 2014. Extending the work of hand-script symbols of the 40 Inventive Principles, the Author is reporting the idea of classifying the 40 principles into 9 groups for easier teaching. The principles are classified into 4-membered groups from the top, with a minor adjustment to make the 8th and 9th groups into 6-membered groups. He has given names to the nine groups, then arranged them in the 9 windows (3x3), and made the path of going through them in a way like a sugoroku game. He explains how to teach and utilize the Principles and their symbols, by using the 'Making harmless' group of Principles 21 to 24. English translation of slides was supported by Toru Nakagawa.  The present site posts the Extended Abstracts  , and slides in HTML   and in PDF

 TRIZ Paper:  Symbolize TRIZ 40 principles (Yoshinori Takagi (Sony))  (Jan. 8, 2015)

Presented at 8th Japan TRIZ Symposium 2012. TRIZ 40 Principles are very powerful tools but 40 are too many to remember.  Thus the Author devised hand-script symbols of the principles by arranging the style of the principle number to represent the meaning of the principle. In this manner, the principles and their numbers have been made easier to remember in pairs.  By using them repeatedly, one can remember the principles by heart and can use, say, the Contradiction Matrix fluently and take notes of principles coming out in mind while reading technical documents, he says.  The present site posts the Author's Extended Abstract and slides in HTML in Japanese, while it has a link to the slides in English PDF at the Japan TRIZ Society site.
