  TRIZ Forum: From the Editor: "Global Network of Public Web Sites in TRIZ: A Proposal for Building Global TRIZ Community" (2) (Nov. 16, 2008)

Toru Nakagawa, Editor of the "TRIZ Home Page in Japan" (OGU), Poster Presented at ETRIA TRIZ Future 2008 Conference, Held at University of Twente, Enschede, Netherlands, on Nov. 5 - 7, 2008.
On the proposal which I posted here on May 25, 2008, I have newly made several illustrative drawings and presented them as an additional Poster at the ETRIA TFC 2008.  Various types of Web sites are considered from 4 different aspects: (1) ways of posting, (2) ways of reading, (3) ways of financial support, and (4) ways of description language.  Desirable ways of Public Web sites are shown from these 4 aspects.  The vision of the Global Network of Public Web sites having both Outward-Looking and In-ward Looking Windows is illustrated in a slide.  The 10 slides well illustrate my original proposal.  English version in HTML  and in  PDF , and Japanese translation in HTML and in PDF .

  TRIZ Paper:"A Brief History of TRIZ" (Nov. 16, 2008)

Valeri Souchkov (ICG Training & Consulting, Netherlands), Posted in the Web Site of ICG Training & Consulting, May 2008; Japanese translation by Toru Nakagawa (OGU), Oct. 8, 2008
This article describes when and how the so many tools and methods of TRIZ have been developed.  The works and events are summarized in the chronological manner, for the whole range of the TRIZ methodology up to the recent days.  A valuable article for mid- to upper-level TRIZ learners.  Japanese translation is posted in this Web site.  The English page gives the introduction and a link to the original version in the ICG Web site.

  TRIZ Paper: "40 Inventive Principles in Microelectronics"   (Nov. 16, 2008)

Gennady Retseptor (AVX Israel Ltd., Israel), posted in the TRIZ Journal, Aug. 2002; Japanese translation by Katsusuke Ichikawa, Oct. 22, 2008
The original paper was posted in the TRIZ Journal 6 years ago.  K. Ichikawa, a retired engineer from Shin-Dengen Kogyo, Ltd., has voluntarily translated it into Japanese and contributed to this Web site.  He actually translated it long ago and read it often during his R&D work in microelectronics for enhancing his own ideas, Ichikawa says.

  On the 10th Anniversary Day of  "TRIZ Home Page in Japan":  Toru Nakagawa (Nov. 1, 2008)

      This Web site "TRIZ Home Page in Japan" celebrates today its 10th Anniversary together with readers in Japan and over the world.  This site is to promote the understanding and real usage of TRIZ by openly publishing information and communications related to TRIZ on not-for-profit basis.  Though I have been operating this site as a volunteer, this site is not a personal but a public forum to be composed of the contributions by readers, as you see already.  It is intended to publish most pages in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners.  On the basis of these experiences, I am now advocating the vision of "A Global TRIZ Community intermediated by Pubic Web Sites built in different TRIZ Communities" for overcoming the language barriers .  During last one year we had over 30600 visits to the top page in Japanese and over 5000 visits to that in English.  Readers' contributions either in English or in Japanese are heartily welcome. We wish that "TRIZ Home Page in Japan" continues to help readers understand and apply TRIZ better in their real problems.

Forum: Conference Report (20): "Personal Report of The Fourth TRIZ Symposium in Japan, 2008 (Held by the Japan TRIZ Society on Sept. 10-12, 2008, at Laforet Biwako, Japan)" (Oct. 26, 2008)

Toru Nakagawa (Osaka Gakuin Univ.), Oct. 26, 2008
The Japan TRIZ Symposium 2008 was held with the participation of 180 people (including 15 from abroad) and 46 presentations.  Besides the official reports and documents (to be posted later) , the Symposium is reported here personally by reviewing all the presentations.  This report in English is posted both in HTML and in PDF (65 printed pages, 4.2 MB).  The review covers the two Keynote Lectures by Amir Roggel and by Sergei Ikovenko, an Invited talk by Yojiro Fukushima, and all the contributed papers presented either in the Oral or Poster Session.  The papers are reviewed according to their categories, e.g., Methodologies, Industrial case studies, Promotion in industries, Usage in education and in academia, Patent research, Non-technical applications, etc.  You can see how TRIZ is understood, applied, and promoted in Japan.  (Japanese page just contains links at moment ; the summary will be posted after my coming back from ETRIA TFC.)]  

 

  TRIZ/USIT Forum: "Comments on “Extension of USIT in Japan: A New Paradigm for Creative Problem Solving” Toru Nakagawa"   (Sept. 18, 2008)

Ed Sickafus (Ntelleck, LLC, USA), Aug. 23, 2008
Comments by Ed Sickafus, the developer of USIT, on Nakagawa's paper presented at Japan TRIZ Symposium 2008.  Sickafus says the transition from TRIZ to SIT to USIT has been guided by simplification, i.e. to reduce structure and to reveal the underlying logic. (See his Keynote Lecture at Japan TRIZ Symposium 2006.)  He recognizes that USIT in Japan is 'regressing' to TRIZ in order to address the demands in Japanese industrial environment.  He suggests about his experimental projects of 4-membered USIT team to address the bottom line of the company.

  TRIZ/USIT Paper: "Extension of USIT in Japan: A New Paradigm for Creative Problem Solving"   (Sept. 18, 2008)

Toru Nakagawa (Osaka Gakuin Univ.), Presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan
I have reviewed how USIT was introduced in Japan and has been extended in Japan for these 10 years. (1) I introduced USIT into Japan as an easy-to-learn TRIZ.  It forms a basis of my 'Slow-but-Steady Strategy' of introducing TRIZ into Japan.  (2) We reorganized all the solution generation methods in TRIZ into the framework of USIT and constructed a system of USIT Operators, having 5 principal methods and 32 sub-methods.  This makes USIT a next-generation TRIZ, forming a basis of 'Steady Strategy' of penetrating TRIZ in Japan.  (3) Data-flow representation of USIT gave the concept of 'Six Box Scheme', which has been realized as a New Paradigm for Creative Problem Solving.  (4) Teaching to university students and training of industrial engineers have been established, and applications to real industrial projects have been carried out in companies.  With all these activities, USIT has been contributing to promote TRIZ in a way easy to learn and apply, i.e. a unique feature of the TRIZ community in Japan in comparison to other countries.  In the English page: Paper , paper in PDF, slides in PDF; In the Japanese page: Paper, paper in PDF, and slides in PDF.

  TRIZ Forum: IT & TRIZ book: "Japanese Translation Project of Mishra's IT & TRIZ Book: "TRIZ Principles for Information Technology" Preliminary Sample Edition" (Sept. 7, 2008)

Masatoshi Hotta (Sozo Kaihatsu Initiative) and Toru Nakagawa (Osaka Gakuin Univ.), Sept. 7, 2008
The Japanese Translation Project has completed its first draft of the whole volume by the end of July.  The Author, on the other hand, has been working for the brushing up of the whole book and sent us the 'final revised version' by early August.  Thus we are working further for brushing up our translation manuscripts so as to reflect the Author's final version.  We have just prepared a 'Preliminary Sample Edition' for displaying at the 4th TRIZ Symposium in Japan.  Some early readers of our manuscripts say "This book explains quite different IT & software techniques from aspects of principles.  The descriptions are interesting and useful for software engineers without knowing TRIZ."

  TRIZ Paper: "No Need for Methods?"   (Sept. 7, 2008)

Peter Schweizer (MethoSys GmbH, Switzerland), Presented at ETRIA "TRIZ Future 2007" Conference, Held at Frankfurt am Main, Germany on Nov. 6 - 8, 2007

  TRIZ Forum: From the Editor: Global Network of Public Web Sites in TRIZ: A Proposal for Building Global TRIZ Community (May 25, 2008)

Toru Nakagawa (OGU), May 24, 2008.
When I rebuilt my page of 'TRIZ Links in the World', I felt much that the language barriers have preventing TRIZ from its better understanding and smoother penetration in the World.  As a practical solution to this problem, I am now proposing here "Let's build many Public Web sites in TRIZ in different TRIZ communities in the World and form a Global Network of them".  Each Public Web site plays the role of the hub site in TRIZ in the community (i.e., typically a country), and posts various papers/articles contributed by many authors under fair leadership of the Editor(s). It posts papers/articles/news of the outside world after translating them into their own language, and also posts the works and news of their own after translating them into a common language, i.e. English.  By forming a global network in Internet of such Public Web sites in different communities, we can build an autonomous and sound TRIZ community in the global scale.  This model of Public Web sites was established partly by the TRIZ Journal and in a more typical form by the TRIZ Home Page in Japan.  There are also other possible bases of forming such Public Web sites in various countries, as discussed in the text.  Full text in English and Abstract only in Japanese

It has long been requested (mostly by Japanese readers) to update the (7-year old) TRIZ Links in this Home Page. The Link pages are now rebuilt as follows: [1] Selected TRIZ Links in Japan and in the World are now posted both in English and in Japanese.  (The Japanese page lists up about 30 sites in Japan, whereas the English page only about 10 sites in Japan.)  [2] Extended TRIZ Links in Japan (about 100 sites) are posted in the Japanese page classified in 9 categories.  (This page will not be translated into English.)  Extended TRIZ Links in the World will be posted in English in a week or two.

  USIT Lecture: "Heuristic Innovation and its Development" (Mar. 30, 2008)

Ed Sickafus (Ntelleck, LLC, USA), U-SIT and Think News Letter - 69 , Mar. 19, 2007; Japanese translation  by Hideaki Kosha (Fuji Film), Keishi Kawamo (formerly Shibaura Inst. of Tech.), and Toru Nakagawa (OGU), Mar. 26, 2008
[Dr. Ed Sickafus, the developer of USIT, gave a Keynote Lecture at Japan TRIZ Symposium 2006 and talked about the idea of extending (or revolving) USIT further.  He completed the idea into the method of 'Heuristic Innovation' (HI) and published a textbook.  In March 2007, i.e. a year ago, he announced this new book in his USIT News Letter .  In the NL, he describes the history in his mental process of developing the HI methodology and introduced HI.  The developer of USIT tried to extend USIT further by use of USIT itself.  While he was thinking what is the undesirable effect in USIT, he met cognitive psychology and realized that USIT gives emphasis on logic, mostly performed by the left hemisphere of our brain, but does not utilize intuition, mostly performed in the right hemisphere.  Even in case of structured problem solving methodology, people who have really mastered it would use it much freely without depending on the process rigorously.  The HI methodology has made such freeness explicitly.  For stimulating intuition, the author advises to utilize metaphors; not only verbal metaphors but also more importantly nonverbal ones such as sketches and diagrams.  This essay has dynamic and deep insights.]

  TRIZ Papers: "Theory of Resolving Differences: A Collection of Papers Written by Toshio Takahara (2003-2007) with Annotated Bibliography" (Mar. 30, 2008)

Toshio Takahara, Dec. 27, 2007
[This page contains all the 14 papers published by Toshio Takahara for these five years and a brief guide to these papers.  The 'Difference' stands for the gap between the reality and what we want or what should be.  Recognition of such Differences and trials of resolving them are the fundamentals in human activities, the Author understands.  Such human activities take various forms and phases, including goal setting, problem recognition, designing, problem solving, etc.  The Author is trying to present a unified method of understanding and representing the whole process of Resolving Differences.  Behind the Author's unique and hence not-easy-to-adopt terminologies, I realized the clarity in the representations and the significance of the theory last October when I was reviewing his paper presented at Japan TRIZ Symposium 2007.  So I asked the Author to record and post all his works here together.]   

  TRIZ Forum: IT & TRIZ book: "Japanese Translation Project of Mishra's IT & TRIZ Book: "TRIZ Principles for Information Technology" (TIC, 2007) " (Mar. 9, 2008)

  TRIZ Paper: "A Method of Resolving Differences Based on the Concepts of Functions and Process Objects: Part 2"   (Dec. 9, 2007)

Toshio Takahara ( ), Presented at the Third TRIZ Symposium in Japan 2007 Held by 'Japan TRIZ CB' at TOSHIBA Kenshu Center, Yokohama, Japan, on Aug. 30 - Sept. 1, 2007
[This is a highly theoretical paper. Though the paper was presented in a Poster session, full papers were published in the Proceedings and posted here both in English and in Japanese.  The Author's way of representing 'Cause-Effect Diagrams' is clear and informative (Nakagawa's 'Personal Report of the TRIZ Symposium' explains this portion of the paper).  With the term of 'Resolving differences', the Author is trying to make a new integrated framework of problem solving, making new function, and idealization.  The paper is difficult to understand, but I now feel a new integral theory is emerging here.  The page contains Nakagawa's introduction, Extended Abstract, and the full paper in PDF .]

  TRIZ/USIT Case Study Paper: "Education and Training of Creative Problem Solving Thinking with TRIZ/USIT"   (Nov. 18, 2007)

Toru Nakagawa (Osaka Gakuin Univ.), Presented at ETRIA 'TRIZ Future Conference 2007' held on Nov. 6 - 8, 2007 at Frankfurt on Main, Germany
[This paper reports my experiences of training industry engineers and educating undergraduate students on how to think creatively with TRIZ/USIT in problem solving. The focus is what to teach them. I gradually shifted my emphasis from TRIZ to USIT.  For training engineers, 2-Day USIT Training with group practices of real problem solving is found effective.  For educating students, giving motivations and basic knowledge is necessary for the education of TRIZ/USIT concepts.  Case studies of technical and everyday-life problems are useful for both targets of people.

Simon Dewulf (CREAX, Belgium), Keynote Lecture Presented at The Third TRIZ Symposium in Japan, Held on Aug. 30 - Sept. 1, 2007 at TOSHIBA Kenshu Center, Yokohama;
CREAX has been carrying out an extensive patent analysis project and building knowledge bases with new frameworks in TRIZ. For improving existing functions and achieving new functions, they recognized the need of change in the attributes (or properties) of the relevant parts in the system. Thus the author proposes a new approach of utilizing the property changes, especially in the form of trends of evolution of technical systems, for creative problem solving.   Abstract , Sides, and Japanese slides

  TRIZ/USIT Case Study Paper: "How to Prevent Unauthorized Persons from Entering the Auto-locking Door of Apartment Building: Applying TRIZ/USIT to A Social & Technical Problem"   (Sept. 13, 2007)

Toru Nakagawa and Arata Fujita (Osaka Gakuin Univ.), Presented at the Third TRIZ Symposium in Japan Held by 'Japan TRIZ CB' at TOSHIBA Kenshu Center, Yokohama, Japan, on Aug. 30 - Sept. 1, 2007
This paper is an extension of Fujita's Thesis work supervised by Nakagawa.  A concise case study of solving everyday-life problem.  Residential apartment building equips auto-locking door system at the entrance.  However unauthorized persons can enter the door easily simply by following a resident, during about 10 seconds of the open door.  This is not a pure technical problem, but rather the problem in the psychology of residents who allow and in the lack of social consensus what to do when two groups happen to meet at the door.  With the discussion in the Thesis Class, the root causes of the problem were revealed to find solutions.  Rules are now displayed clearly that inside the door is a private zone, that every group must get authenticated, that the authentication should be done regardless the door is open or closed, and that the group should input the current number of members, etc.  At the same time, a new control system with real-time image recognition capability is installed in order to monitor the number of people who entered the door, and to alarm when any person enters the door exceeding the number of authenticated persons.  The door is mechanically and physically operated slowly as before for the sake of safety, but an invisible logical door based on information processing is working instantaneously to show signs, notices, and alarms.  In this manner the problem of human psychology and social rule is solved and the new rule is ensured by a new technical system.  An expert in the security problem commented me 'a cool solution!' in the Symposium.  Extended Abstract , Abstract of the Thesis , Full paper in Japanese , and presentation slides are posted. ]

  TRIZ Case Study Paper: "Super Effects: The Synergistic Effects of TRIZ (The Theory of Inventive Problem Solving): Significance of the Insulated Wirebonding Technology X-Wire"   (Sept. 13, 2007)

Gunter Ladewig (PRIMA Performance Ltd., Canada) and Robert Lyn (Microbonds Inc., Canada), Presented at TRIZCON2007: The 9th Annual Altshuller Institute for TRIZ Studies Conference, Held at Louisville, Kentucky, USA, on Apr. 23-25, 2007.
Japanese translation by Katsunori Ishikawa (Shindengen Electric Manufacturing) and Toru Nakagawa (OGU), Sept. 6, 2007
[This is an excellent case study presented at TRIZCON2007.  In semiconductor devices, the performance of the chip is limited by the interconnection between chips and between chip and substrate.  The current wirebonding technology with non-insulated wires uses only the peripherals of chips for the connection.  More advanced technology is currently the Area Array Flip Chip.  With reference to the TRIZ Trends of Evolution (especially the Geometrical Evolution of Lines), the phase of 2D lines/curves has not been fully deployed and skipped without solving contradictions, the Author says. They have developed the insulated wires, developed a kit to use the insulated wires on the ordinary widely-spread wirebonding equipments.  Their new technology ('X-Wire') can make wirebonding densely and freely without worrying about shortening. The new technology would make a lot of chain reactions of benefits (so called 'Super Effects') in the semiconductor industries, the Authors expect.  It is remarkable that TRIZ has given a clear guideline in the technology development.  Nakagawa evaluated this paper highly in his Personal Report of TRIZCON. Japanese translation of the paper has been posted in HTML and in PDF .  In the English pages, Nakagawa's introduction in HTML and the original paper in PDF are posted.]

Toru Nakagawa (Osaka Gakuin Univ.), Aug. 17, 2007
[This is an introduction to a new book written by Umakant Mishra (India) and prepublished from Technical Innovation Center (USA) as a draft edition.  In this book, all sorts of techniques in the field of IT, mostly software, are collected and classified with respect to the essences of innovative/improving ideas of them according to the TRIZ 40 Inventive Principles.  In this process, the TRIZ 40 Principles need to be explained, adopted, extended, and modified so as to match the IT/software field; the Author has done this work excellently, I have found. The book describes 1000 items of techniques (in 1-3 lines each), 100 patents (in 10-20 lines), and 100 case studies of techniques (in 10-20 lines) according to the hierarchical classification of Principles, subprinciples, and keyword items.  So far we heard many people say 'TRIZ is not applicable to IT/software field'.  This book is a wonderful collection proving that 'TRIZ is applicable everywhere in IT/software field'.  I wish to translate this book into Japanese and to publish (or more exactly get it published) in Japanese edition.  I think this book should be addressed not to small TRIZ audience but to much larger IT/software audience; thus the book title would better be something like "Innovative Ideas in IT/Software Technologies Classified with TRIZ Inventive Principles".  My Japanese page is composed of (1) Introduction of this book (an excerpt of my 'Personal Report of TRIZCON2007'), (2) Contents of the book shown by outlines and examples, and (3) Request of volunteers for the translation project. (The page has been fully translated into English. (Sept. 13, 2007))

Japanese translation by Masahiro Saitoh (Yanmar Co.) and Toru Nakagawa (OGU), Aug. 4, 2007
[This is a paper on an amazing invention and its evaluation with TRIZ.  The invention is a new type of Motor (in its basic meaning of 'generating motion') which does not use electricity.  The invention is 'A new type of Motor having two (or multiple) rotors of nonlinear spiral teeth'.  Though ordinary combustion engines generate reciprocal motions of a piston, the new motor generates rotational motions of shafts directly.  By applying a part of this invention concept, pumps and screws (or marine propeller) can be realized.  In fact, the authors built a new type of marine propeller and demonstrated it successfully in a public experiment.  The area of application of this invention is supposed to cover combustion engines, Diesel engines, rotary engines, turbines, electric motors, pumps, compressors, vacuum pumps, propellers, marine propellers, etc.  Reading this brief introduction, you must feel confusing, puzzled, and unbelievable; then why don't you read the original paper three times closely.  As a matter of fact the new marine propeller was demonstrated successfully in May 2004.  I reported this paper in my 'Personal Report of ETRIA TFC2007' .  Japanese translation of the paper has been posted in HTML and in PDF .  In the English pages, Nakagawa's introduction in HTML and the original paper in PDF are posted.]

[App. 70 participants,  22 papers published in the Proceedings.  Reviewed all the actually-presented papers from my personal point of view and reported in English (summary alone in Japanese).  A Keynote Lecture was given by Alla Nesterenko (Russia) on her experiences of teaching school children (K-12) on the basis of TRIZ; during TRIZCON2007 Education Workshop was held in order to make a proposal for a similar education project in USA.  For further development of TRIZ methodologies, two papers presented by Hyman Duan at al. (China) and by Sergey Malkin (USA) are remarkable in their trials of developing new easy-to-learn TRIZ software tools.  We had two excellent case study papers in technologies: Gunter Ladewige et al. (Canada) developed, with the guidance of TRIZ principles, a novel wirebonding technology, 'Microbonds', where wires insulated with 1 micron-thick coating can be bonded densely and flexibly; the new technology is expected to have super effects (i.e. a lot of chain effects) in the microchip industries.  Tzu-Chang Chen (Taiwan) reported a powerful way of evaluating patent portfolios with ordinary IP methods plus TRIZ.  It is a pity that contributions from US industries and US academia in research are decreasing for these several year in TRIZCON even though contributions from Asian countries are increasing. ]

  Case Study: Problem Solving with VE: "Development of a Movable Office of Ticket Vending Machines for the Construction Works of Remodeling JR Osaka Station"   (Apr. 5, 2007)

Kouji Katayama (Western Japan Railroad), Presented at The 38th Kansai Value Engineering Conference, Held by Japan Value Engineering Society, on Feb. 16, 2007, at Osaka International Communication Center, Tennoji-ku, Osaka. 
[For the construction works for remodeling JR Osaka Station, an office of ticket vending machines was found necessary to move and reinstall several times.  Conventional way of moving the office takes 40 days with temporary enclosures at the new or old location, causing much inconvenience with narrowed pathways.  The author developed a method of moving it just one overnight and performed it successfully.  The keypoint in the problem solving method in this report seems to be the processes of clarifying the problem in a hierarchical scheme, converting the expressions of problems into those of tasks/targets, and then generating a hierarchical system of target solutions.  This is one of VE methods, the author says, but it should certainly be useful in problem solving with TRIZ/USIT.  An excellent case study!  The paper is posted in PDF .]

Lu (USC, USA).  On further extension of the TRIZ methodology, Keynote by Aleksey Pinyayev (P&G, USA) and a contributed paper by Simon Dewulf (CREAX, Belgium) are interesting to me. As a case study report, the invention of "A New Motor" by Vratislav Perna (Czech) and its evaluation by TRIZ experts, Bohuslav Busov (Brno Univ. of Tech., Czech) and Pavel Jirman (Tech. Univ. of Liberec, Czech), are tremendous. The new motor is composed of a pair of 'nonlinear screws' and can be, in future, a disruptive technology against normal combustion engines, rotary engines, and jet turbines! They made a marine propeller with the new concept and demonstrated its superb characteristics in their video presentation.  -- Anyway, by reviewing the Conference papers we can learn the current state-of-the-art and future directions of the TRIZ methodology and its applications. ]

  On the Eighth Anniversary Day of  "TRIZ Home Page in Japan":  Toru Nakagawa (Nov. 1, 2006)

      This Web site "TRIZ Home Page in Japan" celebrates today its Eighth Anniversary together with readers in Japan and over the world.  This site is to promote the understanding and real usage of TRIZ by openly publishing information and communications related to TRIZ on not-for-profit basis.  Though I have been operating this site as a volunteer, this site is not a personal but a public forum to be composed of the contributions by readers, as you see already.  The Official Pages of the 'Collaborative Board of TRIZ Promoters and Users in Japan' have been posted in this site since last year, enhancing its public service. It is intended to publish most pages in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners.  During last one year we had over 31600 visits to the top page in Japanese and over 5200 visits to that in English.  Readers' contributions either in English or in Japanese are heartily welcome. We wish that "TRIZ Home Page in Japan" continues to help readers understand and apply TRIZ better in their real problems.

[Sickafus is the originator of USIT.  Any structured problem solving methodology, such as TRIZ, USIT, etc., teaches us to solve problems following clear structure.  However, Sickafus argues, the human brains work more freely, not only at the conscious level but also at the subconscious level.  Thus he advises us to utilize such a power of our brains.  While the conscious uses logic, the subconscious can be activated with metaphors, such as images and words.  Thus he advises us to solve problems without being constrained with the structured logic.  In Japanese traditional art students are trained to "Enter the Form first, and then get out of it".

Section J. In order to realize the solution ideas, keep improvement of the ideas by drawing various designs in your diary, and make prototypes.  Combine solutions, and optimize the design by using, say, the Taguchi Method.  Then file a (provisional) patent, and try to license it by personally meeting appropriate people (or try to manufacture it for yourself). 
Section K describes the Ideal Final Results and Inventive Standards. Since these concepts are closely related with Section B through Section E, they are explained here separately. Section L shows a table of Knobs (i.e. attributes), and demonstrates how to generate solutions by fully utilizing such Knobs.  Section M shows the Trends of System Evolution.

[Paper presented last November, and has been waiting in the 'To Do List for TRIZ'.  Many of TRIZ beginners try to deal with cost-related issues, meet difficulties, and decide that TRIZ is of no use.  Since the cost problem covers a very wide range of issues, we need careful analyses, the author says.  Besides, we TRIZ experts should construct/re-arrange TRIZ methods in such a way that TRIZ beginners can tackle cost-related problems with TRIZ, the author says and actually suggests a version of such an approach.  Important paper for teaching/learning TRIZ.  Posted in HTML and

Series: Course Materials Illustrated (5): "Hierarchical TRIZ Algorithms" . "I. Resolve Resulting Contradictions "(Jul. 4 , 2006)

Larry Ball (Honeywell, USA), Posted in TRIZ Journal since May, 2005; Translated by Toshio Takahara and Toru Nakagawa (Osaka Gakuin Univ.), Jan. 5, 2006.
[5th posting of the intensive Course Material on a simplified form of TRIZ. Section I. It is critically important to understand the contradictions.  In conventional TRIZ theories, the concepts of Technical Contradictions (e.g., 'The rake may be improved in collecting debris while getting worse in extracting debris from the ground') and Physical Contradictions (e.g., 'The tines of the rake must be flexible and must be stiff') are used; however we should better have the concept of 'Complete Contradictions' unifying them (e.g., 'The tines of the rake must be flexible for collecting the debris and must be stiff for extracting debris embedded in the ground').  Diagram representation of the Contradictions are illustrated.  The Separation Principles for resolving these Contradictions may be extended from the ordinary ones of separation in space, in time, and between the whole and the parts, to new ones like gradual change, in direction, in perspective, in characteristics of the field, between substances and fields, etc.  The author has shown a large number of illustrations of classification of Contradictions and of various Inventive Principles for solving them.  -- This Chapter is the highlight of Ball's algorithm and contains a lot of useful insights.]
