Editor's Note (Toru Nakagawa, May 13, 2005)
This is a personal report of TRIZCON2005 held four weeks ago near Detroit. (See Altshuller Institute's Official Web site.) About 150 people (including about 70 people from Delphi) attended at the conference and presented/discussed a wide range of TRIZ research and applications. Here I am trying to personally review the presentations/papers of the Conference and to post it publicly. Please remember that the description here is my personal view reflecting my impression and may have any possiblity of misunderstanding and biases whatever efforts I made to understand them fully and faithfully. I know that any presentation/paper/event may have different relevance and give different impression to any other people. (Moreover, unfortunately I am not good at taking notes of presentations/discussions spoken in English, and hence a lot of important information given in speech without records in the Proceedings are missing here.) Nevertheless, this kind of report should be helpful for many people in the world to understand current progress and future directions of TRIZ, I hope. If you find any mistake/misunderstanding in this report, please let me know via email. (You may also be interested in referring to my previous reports of TRIZCON2004 and ETRIA TFC2004 .)
In separate pages, I have posted my own two papers prepresented at TRIZCON2005. The first one, i.e. "Software Engineering and TRIZ (1) Structured Programming Reviewed with TRIZ", is posted in English (Japanese translation will not be prepared for a time being, because its earlier and more detailed versions are posted already). The second, which was orally presented at the conference, is "Overall Dataflow Structure for Creative Probelm Solving in TRIZ/USIT", and is now posted in Enlish (and in Japanese already on Apr. 5, 2005). I also wish to repost a sellection of the TRIZCON2005 papers here in near future with the courtesy of authors both in English and in Japanese translation.
Note (T. Nakagawa, May 31, 2005)
This Personal Report was done by May 13 more or less in the current form, i.e. all the papers are arranged in groups and important/interesting papers are described in some detail. Since then I could have found very little time to wirte the rest. I have now decided to finish this report quickly with only minor insertions and to post it as soon as possible, hoping to meet readers' interests better.

|Closing Remarks (Larry Smith)|
This is the 7th TRIZ Conference annually held by the Altshuller Institute. The Altshuller Institute for TRIZ Studies is a not-for-profit organization established in USA in 1998 for wider promotion of TRIZ in the Western world (See its Web site: http://www.aitriz.org/ ). The Conference, named TRIZCON, has been held at different cities: Novi (near Detroit) in 1999 , Nashua (near Boston) in 2000, Woodland Hills (near Los Angeles) in 2001, St. Louis in 2002, Philadelphia in 2003 , Seattle in 2004, and in Brighton (near Detroit) this year. Details of the organizing work was carried mostly by Mr. Richard Langevin, Executive Director of the Institute.
total number of participants
was announced to be about 80 plus 70 from Delphi, the principal
supporter of this conference. Participants came
from USA and various other countries over the world including UK,
Germany, France, Austria, Israel, Mexico, Korea, Japan, and P.R. China
(cf. the list of participants does not show the countries).
Delphi supported the conference by providing with their auditorium and
meeting rooms etc. and utilized the conference pro-actively for
promoting TRIZ in their company by sending many engineers in the
tutorials and symposiums and by Web casting the conference to their
several sites including one in Mexico.
first day, Tutorial
were held in three parallel tracks, one for introductory, another for
introductory especially in Spanish with Web-casting to Mexico, and
the third for advanced topics. About 100 people attended at
these tutorials. This year I attended at Ellen Domb's
introductory class; she conducted group practices several times
including her famous training of "Find resources to survive at the
Titanic accident". These tutorials must be helpful for the
to learn the basic concepts of TRIZ and some advanced
of TRIZ from masters of TRIZ.
The second and the third days are for Symposium. The schedule was similar to the previous ones. Keynote speech and two Panel Discussions were scheduled for 90 minutes in plenary sessions, while ordinary presentations for 60 minutes in two-track parallel sessions. Most sessions finished about 10 minutes earlier than the time table, giving much time for private discussions.
The Proceedingswas given to the participants in a CD-R disk, starting this year. It was handy to carry back to Japan but not good to read during the conference. Thus during the conference I had to consult my print of the abstracts downloaded from the Web. The Proceedings contain 28 papers as listed at the bottom of this report (4 papers of them were not presented orally). Keynote Speech and Panel Discussions did not provide any printed material. Altshuller Institute's Journal "Izobretenia", Vol. 6, was also published and contained in the CD-R disk.
Topics of the presentations
cover a wide range, while the sessions seem not arranged in any clear
In this report I am going to group them in the following categories:
(A) Promotion of TRIZ in Industries and in Academia
(B) Methods of Applying TRIZ to Technology Problems
(C) Case Studies of Solving Technical Problems in TRIZ
(D) Application of TRIZ to Business, Management, and Human Problems
Keynote Speech and Pannel Discussions were important sessions, of
course, but since no printed materials were provided and since I could
not take notes of them, I would like to omit them in this report.
It should be nice if some official record of them is posted
to review almost
all the papers below. However, since I attended only half
the presentations (due to the parallel sessions) and read all the
only after the conference, please pardon me if I do not understand some
of them in their heart.
[P.S. Only half of the papers are actually described here
closely. (T.N., May 31, 2005)] I am grateful to the Altshuller Insititute and to the authors who have given me the permissions of quoting their figures here.
(A) Promotion of TRIZ in Industries and in Academia
How to promote TRIZ successfully in industries and in academia is an
important issue of TRIZCON this year, as well as for these several
years. The Keynote Speech [A] has presented the approach and
experiences in Delphi, and the Panel Discussions [B, D] have shown
various approaches and trials related to this issue.
Len Kaplan (OutCompete, USA)  has shown a thoughtful presentation with the title of "Three Main Flops of TRIZ -- And How to Avoid Them". From his experiences of 15 years of TRIZ consulting, he discusses about strengths and weaknesses of TRIZ in three faces, i.e. TRIZ as method, TRIZ as consultancy, and TRIZ as business. He argues that the following three points, which are usually supposed to be the strength of TRIZ, are the main flops (i.e. weak and bad points) in TRIZ:
In relation to the first point, he argues that Altshuller's initial intention of finding 'how to invent' has already shifted in TRIZ to 'how to solve problems' and that 'inventiveness' is usually not the most important criteria for a good solution to a real problem. In real problems, there are cases where no root contradictions are localized, e.g. cost reduction problems and new system/process development problems. Thus if the request to discover and solve the "root cause contradiction" is stressed, it hurts the applicability of the TRIZ method to real problem solving. Hence Kaplan proposed to reconsider this methodological "corner stone" and replace it with another one, more suitable (though the new one is not stated explicitly).
In conclusion, Kaplan states the following "Manifesto":
Dear TRIZ colleagues!
We don't have any choice but stop the nonsenseof fighting against our own clients, their beliefs and expectations. Let us better focus our efforts on non-intrusive ways to make our clients' job easier.
Ou own psychological inertia hurts us, the experts in "overcoming" this invisible enemy. We can see how it hurts others; why can we not see our own problems?
This is our opportunity to place TRIZ in the proper prospective of helping our clients, differentiate ourselves from competition, and succeed in our business.
We must support our clients in improving their problem-solving abilities in a way compatible with their "traditional" activities; otherwise, the TRIZ knowledge will be forgotten, problem-solving skills will disappear, and bad experience witll finish the job of creating the negative attitude toward TRIZ. Our problem-solving-supporting tools must be intuitive and empowering rather than complex and confusing.
I invite to this discussion those who distinguish a wish from reality.
I start this discussion by describing my own vision of the future of TRIZ; evolution through resolving the major flops.
Kaplan then suggests a new, more reasonalbe set of assumptions. One of them states as:
The purpose of addressin the challenge (problem) is "to impove the client's situation" rather than "to get rid of the problem" or "to invent".
Praveen Gupta and Shan Shanmugham (Quality Technology Co., USA)  talked with the title of "Institutionalizing Innovation". Their main message is that effective use of TRIZ requires infrastructural support and commitment to innovation. One interesting point in their paper is the following conceptual equations, regardless of its logical foundation and effectiveness:
Innovation value = Resources * (Speed of thoughts)2
Speed of thoughts = Function (Knowledge, Play, Imagination).
Richard Platt (Intel, Israel)  has presented a talk on "Enabling Innovation in the Corporate Environment: Champions, Results and Infrastructure".
Joseph P. Cool (Cool & Associates, USA)  talked on "Marketing TRIZ in the Global Marketplace: A Primer".
There are four papers related to the promotion of TRIZ in education of engineers and engineerign students. It is remarkable that all of them came from Korea and China.
Kyeong-Won Lee (Korea Polytechnic University, Korea)  has presented with the title of " TRIZ Education at Universities in Korea and Their Activities for Expanding Mutual Cooeration with TRIZ Team at Big Companies in Korea". Since I had a prior chance of listening to his presentation on the same topic in Tokyo on Feb. 24-25, 2005, I chose the other track to attend at. It is remarkable that his two excellent case studies are the results of his university classes; they are 'Super-water saving toilet' (see TRIZ Journal (Nov. 2003) and TRIZ HP Japan) and 'New mosquito traps' (See ETRIA TFC2004 ).
Zhao Xinjun (Northeasten University, P.R. China)  contributed a paper "Research and Development on TRIZ in China ". See his article in this Web site TRIZ HP Japan, Nov. 2004 .Haibo Duan and Yue Lin (IWINT Inc, P.R. China)  has presented with the title "Innovation Education Principles with Computer Based Training System." Seems to be essentially the same as their ETRIA TFC2004 paper.
Zhang (IWINT Inc., P.R. China)
and Zhanwen Niu (Tianjin
University, P.R. China)  has given a presentation
on " Successful TRIZ Education Experience
in University". This paper describes two simple but
interesting case studies done by students at Tianjin University.
(B) Methods of Applying TRIZ to Technology Problems
Improving the TRIZ methodology itself is certainly an important issue
in the TRIZ conferences. This year, the paper by Zlotin and
Zusman on the concept of Resources reflects their decades long study of
TRIZ. There are several other works which try to integrate other
methods such as Value Engineering, Lean Engineering, EMS Modeling,
Case-Based Reasoning, Artificial Intelligence, and Software
Engineering. The paper by the present author on the overall structure
of TRIZ is supposed to have special significance to understand
the framework of creative problem solving in general.
Boris Zlotin and Alla Zusman (Ideation International Inc., USA) have been publishing imortant papers reflecting their decades-long study on various aspects of TRIZ. This year they have presented a paper  with the title "The Concept of Resources in TRIZ: Past, Present and Future". Their paper (having 60 pages in total) consists of three parts, i.e. Theoretical Findings (related to the concept of resources), Practical Instruments (showing the details of the findings), and Appendix. Study of TRIZ has extended the concept of Resources wider and wider, so as to include the terms like 'Readily-available resources', 'Derived resources', 'Evolutionary resources'. Zlotin and Zusman define a Pattern of Evolution: "Evolution towards the increased involvement of resources"; this means that Technical Systems in general have been found to evolve (or historically develop) towards the increased involvement of resources.
figure (i.e. Fig. 4 of ) illustrates that the effective use
of various types of resources is the key to develop a technical system
toward ideality. Unfortunately, however, the present author feels
that this figure wants to show too many things in an confusing way;
e.g. the acronym 'FFIISSTT' obscures the structure of the concept of
and Zusman , their 'resource checklist' seems to be structured in
the following way:
Although (or because) Zlotin and Zusman's paper  is so extensive
and intensive, it is not easy for me to understand their present
concept of Resources; maybe I should read their paper again more
Proseanic, and Svetlana Visnepolschi (Ideation
International Inc., USA) (Quality
Consulting, USA)  have presented a paper with the title of "Integration of Value Engineering with TRIZ through FAST Diagrams." In short, the authors
propse to use the Problem Formulator tool of Ideation International's
TRIZ methodology in the idea generation with VE. Their case
study of a Stapler Remover is not so attractive unfortunately.
Boza and Rick Gour(TRW Automotive, USA)  contributed a paper "Combining
Value Engineering and TRIZ in
Automotive Industry." Their document in the slide style, without
actual presentation, is difficult to comprehend how they really use
Steven Ungvari (Institute for Lean Design, USA)  has presented another important paper with the title "Lean/TRIZ: Eliminating Waste in Product Development through Innovation". Lean Engineering was originally developed in Toyota Motor Co., Japan, with the notion of efficiency especially in the form of lack of waste and wasteful processes. It has been introduced in the US industries for over a decade. Ungvari has presented a general scheme (Lean/TRIZ) of combining TRIZ with Lean so as to eliminate the lifecycle waste with the 'latent' innovation capability of TRIZ especially at the design stage.
Ungvari adapted the TRIZ concept of Ideality into 'Universal Lean Design Equation' in Lean/TRIZ. The Lean/TRIZ Idealty has the 'Customer values' as the numerator while the 'Evil Ings' (i.e. lifecycle engineering costs) as the denominator. In developing a new product or service, the development team should try to increase the 'customer values', which may be represented with the following eight factors:
'Customer Ilities': Performability, Affordability, Featurability, Deliverability, Useability, Maintainability, Durability, and Imageability
(Ungvari notices that there are also the 'company values' which may be represented by the following eight factors:
'Company Ilities': Profitability, Investability, Riskability, Produceability, Marketability, Growability, Leverageability, and Respectability
There are often conflicts among the Customer Ilities and the Company Ilities; the development team has to foresee and solve such conflicts. Ungvari call them 'minor/moderate conflicts' in the paper, in order to address the 'major conflicts' between the Customer/company values and the lifecycle engineering costs.)
As the denominator
of the Lean/TRIZ Ideality, Ungvari has chosen 'Evil Ings', where 'Ings'
mean subsequent tasks that have to ocur as a result of the design
process, e.g. cutting, shaping, welding, boring, storing, inventorying,
moving, counting, disposing, etc. Parts of those Evil Ings may be
detectable through 'Activity Based Accounting' but larger parts of them
are hidden. For reducing the impact of 'Evil Ings', Ungvari
points out the importance of understanding their root causes. He
suggests seven root causes of bad designs resulting in lifecycle
waste. They are:
'Root Causes of Evil Ings': Complex, Precise, Variable, Sensitive, Immature, Dangerous, and Skill Intensive.
Thus the major challenges for the development team are now clearly defined in the following figure (Fig. 4 of ):
further goes on to discuss how to do Lean/TRIZ in the four lifecycle
domains of a product, i.e. Customer Domai, Design Domain, Supply
Domain, and Manufacture Domain. He shows the 'Five Laws of
Lean/TRIZ Design' as the guideline for the design process. For
setting up the design strategy, he proposes a method named 'Lean/TRIZ
Design Strategy Mapping', which is based on the strategy of 'Start with
the end in mind'. -- I am much interested in the way the author, Steven
Ungvari, has shown the major challenges for product development.
The spirits of TRIZ and Lean Engineering are nicely combined to show
universal challenges for innovation.
Madara Ogot (Pennsylvania State University, USA)  has given a presentation with the title
of "Use of EMS Models to Enable the
Effective Use of TRIZ System Operators in Engineering Design". He
has demonstrated how to draw EMS (Energy-Material-Signal) Models within
the 9-windows in TRIZ. It is not clear how
effective/useful it is.
Guillermo Cortes Robles, Stephane
Negny , Jean-Marc Le Lann, and
Pascale Zarate (ENSIACET, Toulouse, France)  have presented their
work on "Innovation
Management and Knowledge Management in Process and Industrial Systems
Engineering: TRIZ and Case-Based
Reasoning". This is an extension of their ETRIA TFC2004
paper (see my Personal Report ).
Mehdi Akbari (Islamic Azad
University of Khomeini Shahr, Iran)  contributed a paper on "TRIZ
Oriented Artificial Intelligence".
A rough idea is described, but seems not feasible.
Toru Nakagawa (Osaka Gakuin University, Japan)  contributed a paper with the title of "Software Engineering and TRIZ (1) Structured Programming Reviewed with TRIZ". [Reposted in the "TRIZ Home Page in Japan", Jun. 14, 2005 ] In this series of papers, I have chosen major topics in software engineering one by one, and reviewed them with TRIZ and fed back principles in software enginnering to TRIZ. Its abstract writes as:
The concept of Structured Programming was examined in this paper. When we see the historical disputes on the "Goto-less" issue from the TRIZ' viewpoint of contradictions, we have found it not appropriate to teach: "the Structured Programming is a proposal to use only three basic control constructs and no Gotos, and it is a compromise with practice to add four more constructs" (as is often taught in computer science classes). It is because only with these additions Structured Programming has its sound bases. On the other hand, the approach of Structured Programming urges TRIZ especially in the following points: (a) TRIZ Principe 1 (Segmentation) should be extended to reflect the idea of Stepwise Refinement; (b) TRIZ Principle 6 (Universality) should be extended to include the idea of establishing/using industrial standards (this has been a blind point of TRIZ due to so much stress on inventions); (c) TRIZ Principle 7 (Nesting) should be regarded more important as reflecting the hierarchy concept of systems.
Toru Nakagawa (Osaka Gakuin University, Japan)  has presented with the title of "Overall Dataflow Structure for Creative Problem Solving in TRIZ/USIT". [This paper is posted in TRIZ Journal, May 2005 and in the "TRIZ Home Page in Japan"]. This paper was presented orally by the present author in place of the first paper  because of its importance.
I have written this paper as an argument against Victor Fey's keynote speech at the ETRIA TFC2004. Victor Fey, one of the TRIZ Masters, talked in his Keynote Speech entitled with "Why Does TRIZ Fly But Not Soar?" as: "The reason for the slow penetration of TRIZ lies in the problem in the ways of distribution of TRIZ and not in TRIZ itself. Trials of simplifying TRIZ, such as done in ASIT and USIT, decrease the power of TRIZ. Don't touch TRIZ!" (See my "Personal Report of ETRIA TFC2004" )
The present author claims the following points as the conclusion in this paper.
Let me explain briefly: It is a basic understanding in TRIZ and in major scientific/technological theories that the following Four-Box Scheme should be used in problem solving. But the scheme is very often modified as shown in the right figure, where a model is chosen first and then the mapping (or abstraction) is done depending on the model. Individual methods in TRIZ may be shown in the right fugure but the whole structure is not well written in the four box scheme.
On the other hand, USIT provides an overall structure as clearly shown in the following Six-Box Scheme. All the essential information needed/derived in each stage is shown in the boxes. If you combine the boxes as enclosed in broken lines, you may find closer relation to the original Four-Box Scheme. It is remarkable that generized problem comes not from models in the textbooks but derived solely from the user's problem with the standard analysis method in USIT. The jumps for obtaining pieces of essential ideas for solutions are assisted by the USIT Operators, a system of symple operators reorganized form TRIZ methods. We do not depend on the ambiguous process of analogical thinking.
At the presentation session and afterwards there were a number of serious and encouraging discussions. Please refer to the paper posted in this Web site ].
Noel Leon, Jose Jesus Martinez, and Carlos Castillo (Tec de Monterrey, ITESM, Mexico)  have presented on "Methodology for the Evaluation of the Innovation Level of Products and Processes (in the TECNOS Award Context)." They are trying to find a scheme of non-subjective criteria for giving award to innovative products and processes in a country scale. A scheme was presented and tested. It should be noticed that such an evaluation scheme may be necessary in enterprises but rather different from the one in the context of a public award.
Studies of Solving Technicla Problems in TRIZ
This year we had several presentations of case studies in technical problem solving. It is usual that companies do not want to report any technical details, but here are some exceptional cases containing details of technical thinking process and technical solutions. We should make the best use of them to learn the good practice of applying TRIZ and the way of thinking in TRIZ.
Young-Ju Kang, Young-Il Kwon, Pyeong-Kwan Chung, and Alexander Skuratovich (LG Cable, Korea)  presented a paper with the title of "TRIZ Applications in LG Cable and Case Studies". The case deals with heat-shrinkable tube to be used for insulating wire connection area. The heat-shrinkable tube has been produced by introducing a rubber tube heated over 200 °C into the expansion equipment shown in Fig. 1. The tube is expanded by use of vacuum and then cooled rapidly by water; and hence obtain some shape-memory effect. The problem of the current product is its inhomogeneous property in the longitudinal shrinking factor.
The TRIZ team
analyzed this problem and found a physical
contradiction: the tube must be hot to expand (in the diameter) and yet
must be cool not to elongate. (The TRIZ team had an experience of
a similar physical contradiction in the problem of pressing a hot metal
plate while avoiding oxidation. So they introduced the
experience, they say.) They found the operting zone to be the
surface of the tube, and the operating time to be 0.01 sec. They
obtained the idea of cooling the surface only of the tube very rapidly
so as to make the hardened skin to resist the friction between the tube
and the expansion equipment. The final solution is demonstrated
in the figure. Peltier cooler is applied at the entrance part of
the expansion equipment in order to get rapid cooling
performance. This solution reduced the fluctuation in the
LG Cable company, in Korea, has introduced TRIZ since 2001, and has been promoting actively especially since 2003 by inviting a Russian TRIZ expert. Depending on the importance of the project, TRIZ team either just supports the engineering team, or works together with the engineering team, or even works together with the engineering and patent teams. 16 projects have been solved with TRIZ since 2003, the paper says.
Valery Krasnoslobodtsev, Ju-Young Lee, and Jeong-Bae Lee (Samsung Electronics, Korea) has presented an excellent and detailed case study, with the title: "TRIZ Improvement of Rotary Compressor Design". Krasnoslobodtsev has over 20 years of experiences in TRIZ, as Associate Professor at St. Petersberg State University, etc. He worked at Samsung during 2001-2004 as an invited TRIZ expert and achieved this case study together with Korean colleagues.
The system they worked for improvement is a compressor to be used for air conditioners, refrigerators, etc. The Rotary Compressor has two cylinders to be operated alternatively for high/low powers, for the purpose of saving energy. There are two rollers for compressing air in the cylinders and a cam bush controls the clearances between the roller and the cylinder, so as to make a small clearance for the working cylinder while a large clearance for the idling cylinder. The cam bush is designed to have two working positions, for making the upper/lower cylinder to work (and the other cylinder idle). Depending on the direction of the compressor-shaft rotation, a driving pin attached to the shaft pushes the cam bush toward one of the two working positions and also drives the rollers. Thus, by reversing the rotation the compressor power can be interchanged. The problem of the current system is that the driving pin makes noise under some operational conditions because the driving pin pushes the cam bush (and hence the roller) not in a constant force during the compression cycle. This noise causes some inreliability of the compressor.
The problem was
analyzed with ARIZ. Functional modeling, Su-Field modeling,
Technical Contradiction, Resource anlysis, Ideal Final Result,
and Physical Contradiction, etc. were derived. And various
solutions have been obtained. The solutions were generated by the
TRIZ experts and shown to the engineering team one by one
(Krasnoslobodtsev talked that this sequential presentation was the
secret of success in encouraging the engineering team to get interested
in TRIZ). 21 solutions were obtained and presented in the
The first solution (Fig. 8 of ) is to introduce a latching mechanism in the driving pin, as shown in the following figure. The driving pin (now called a multifunctional pin) has a movable part, which serves as a latch for fixing the pin at the working position of the cam bush by the effect of the centrifugal force of the shaft rotation. When reversing the shaft rotation, since there is no centrifugal force, the movable part is pushed inside the shaft due to the spring force.
Another solution (Fig. 9 of ) is to introduce a fixative pin at the opposite position to the driving pin. The fixative pin works to fix the cam bush by virtue of the centrifugal force only during the rotational operation. This idea of a fixative pin may be modified into various types of stoppers, such as a small disk supported by a flat spring board, a ball (as a stopper) inside a groove, a specially-profiled stopper inside a groove, a roller stopper inside a groove, etc. The fixative pin may be set on the cam bush (instead on the shaft), as a reverse design.
Another series of solutions are to introducing asymmetry in the setting of the blade for smoother operation in the compression cycle and also to introduce multiple blades around the circumference of the cylinder for more averaged output pressure of the compressor. The multiple blades solutions seem to be effective in improving the compressor performace, even though not being patentable.
The solutions are evaluated and tested, and some of them were introduced into the mass production. They applied 9 international/national patents. The annual cost saving from the mass-production solutions is estimated to be about $10 Million. The project were granted the Samsung Achievement Award in 2003, the paper reported.
-- This case
study is really amazing especially in the point that the authors
generated better and better solutions. During the Q&A of the
oral presentation, the author especially mentioned about this point of
sequential generation of solutions: "Even though only one 'best'
solution is usually shown in textbook examples of
applying ARIZ, it is important in real applications to generate
better and better solutions for one problem." I feel there is
another issue to discuss about in this case study: In this case, the
TRIZ Experts have generated solutions and have actually designed them
in detail. In ordinary cases of industries in Japan (and in most
other countries), the roles of TRIZ (or USIT) experts should be more
limited and instead the roles of engineers should be much
increased. Namely, the experts (or experienced people) of problem
solving methods should work collaborately with the subject-matter
experts (or experienced engineers).
Darrell Mann (Systematic Innovation Ltd, UK) and Juergen Jantschgi (University of Leoben, Austria  have presented their work achieved in the EU's SUPPORT program, with the title of "Case Studies in TRIZ: Renewable Energy Systems". The main aim of the project was to develope an educational materials for sustainable designs. The paper seems to stress on the general importance of promoting sustainable design/engineering by applying TRIZ.
Their first case
study shows a TRIZ approach to the improvement of Wind turbine
design. They show that the TRIZ knowledge of Trends of Evolution
can readily be applied for suggesting ideas for improvement. As
an example, for generating ideas of improvement of the wind-turbin
blades, the knowledge of step-wise jumps along the Trends of Evolution
was applied in the follow way:
The merit of this method lies in its simple logic of application and yet its effectiveness and power of stimulating a lot of useful ideas. This power will be enhanced by user's experiences and knowledge of examples.
Their second case study is to find odour control processes within water treatment systems. This case study is not at the stage of showing practical solutions but rather of demonstrating the importance of sustainable zero-emission engineering. For building up a system of sustainable solutions, knowledge bases of sustainability-focused, functionally-classified effects would be a great service. TRIZ community could help to create them, they say.
Isak Bukhman and Stephen Brown (Invention Machine Corp., USA)  also presented a paper demonstrating "A Repeatable Process for Improving Sustainable Wind Energy Generation". Their process is rather voluminous as shown in the following figure of "Project Roadmap". Within the ARIZ parts, traditional TRIZ methods are empowered by the Invention Machine's software tools (Gold Fire Innovator).
They have created 32 solutions by using TRIZ, Value Engineering, and Information Fund (i.e. Scientific Effects Liblaly, Patent Collections, and Web based information). After evaluation, they have shown the following 6 concepts. -- These concepts are interesting indeed for me, but the paper does not claealy show how they have been developedactually.
Solution (1): Trimming the gear boxes and connecting the stator of permanent-magnet synchronous generator directly with the blade.
Solution (2): Doubled blades rotating in the opposite ways.
Solution (3): Adding stationary blades behind the rotating blades for the purpose of suppressing turbulent air stream and imporving the propeller efficiency.
Solution (4): A blade in the form of Mobius strip is fixed on a shaft by means of spokes.
Solution (5): Using hydraullic constructionf of the blade, the rigity of the blade is adjusted by the pressure so as to best match the wind speed.
Solution (6): Make the rear part of the blade flexible and controllable with an actuator.
Simon Litvin (GEN3 Partners, USA)  has presented an interesting presentation (though I missed) with the title of "Objective Criteria of WOW Effect in Consulting". For attracting the customers, he says, the consultants should demonstrate some real results which the customers say "Wow!". He shows the following 4 categories of "Wow" demonstrating each with one wonderful example.
(1) The project outcome significantly exceeds what had been initially promised. -- Example: Xerox Corp. once had a problem in their toner packaging process. The toner is apt to clog the gaps for pouring the powder into a tube, even with mechanical activators. GEN3 analyzed that the toner packaging process could be sped up by converting the toner into a fluidized state, which could be accomplished with the aid of a specialy selected mode of vibration. A natural disbelief in the presented extraordinary results represents and additional problem. Such disbelief could be eliminated by comprehensive substantiation, starting with a convincng and illustrative experiment. To work out such experimental substantiation, GEN3 uses 'Function-Oriented Search' with the support of a large body of technology experts 'Global Knowledge Network'. GEN3 designed and manufactured a unique vibro-activator and mounted onto Xerox's standard equipment for the toner packaging. The result of the vibro-activator operation was phenomenal: thevelocity of toner flow increased 18-fold (i.e. by 1800 %).
(2) The project states and solves an utterly non-trivial problem. -- Example. Once they worked with Proctoer & Gamble on manufacturing method of instant coffee. The initial problem statement was: "Develop a method for producing a version of instant coffee that, when dissolved in hot water, would be indistinguishable from freshly brewed natural coffee". The author worked from a quite diferent angle, and re-stated the problem as: "Propose a method for quick and effective brewing of natural coffee in a cup with boiled water, where the liquid wold not turn cloudy, and would not cause a grainiy sensation in the mouth". This problem statement quickly led to a conclusion: the human tongue cannot react to particles smaller tan a certain size. Hence, the solution to the problem lies in simply reducing the size of coffee granules. The problem is solved. No traditional coffee making, no paper bags, and much simpler production process. After this conceptual solution, a grinder of required capacity was found thour the standard 'Function-Oriented Search'.
(3) The project provide an utterly non-trivial solution for a known problem. -- Example. General Electric coame to GEN3 with the request of reducing the manufacturing cost of their snap switch. The typical approach is to reduce the number of different types of components. By using Trimming and then Another dimension, the author has designed a snap switch composed of two identical parts. One of the parts turned by 180° and is assembled as shown in the figure. An operational prototype was really convincing to the customers.
(4) The project proposes a solution that is absolutely ready for implementation. -- Example. A Russian company asked GEN3 to reduce the manufacturing cost of disposable razors. It was known that a process of cementation (surface hardening) in a tunnel oven with NH3 causes a number of problems. Thorough analysis of the whole procedure revealed that the razor sharpening process after the cementation actually strips off the cemented layers. Thus the hardened layer is not involved at the cutting edge. Hence the troublesome cementation process was just eliminated without affecting the quality of the blade. Usually this kindof solutions are associated with historically formed circumstances, which no one ever thoroughly analyzed or questioned, the author says.
All these four examples are very interesting. It is worthy of
studying closely how the problems are analyzed and solved.
Importance of demonstrating the solution concepts with experiments and
prototypes is stressed much in this presentation. -- The
present author understands such importance but also suppose that this
kind of demonstration exceeds the range of TRIZ as a problem solving
methodology (or the ordinary capability of a TRIZ practitioner).
So we should understand the necessity of some organizational system for
TRIZ specialists to work cooperatively with engineers in the fields; a
global network of engineers ('Global Knowledge Network') is for GEN3
while a intimate group of engineers inside our own companies.
Function-Oriented Search seems to be the powerful method for supporting
Mansour Ashtiani and Stephen Dourson (Delphi Corp., USA)  have given a presentationwith the title of "Applying TRIZ/Semantic TRIZ to Root Cause Analyis, Design, and Refinement of Automotive Components." Two case studies are reported. The first is the combined use of TRIZ with a CAD simulation tool for solving a problem in a vlave disc. The second is the application of TRIZ and its software tool for finding root causes in case of breakage of an Integral Cinching Latch Actuator. The authors say Delphi is integrating TRIZ into their Six Sigma program.
Alexander Kynin, Seunglhee Suh, and Seungheon Han (Samsung Electro-Mechanics, Korea)  have presented a paper on "Use of TRIZ at Creation of New Materials." This paper introduces a method of predicting the properties of a polymer by interpolating the known properties of polymers. I was disappointed much after listening.
(D) Applicaton of TRIZ to Business, Management, and Human Problems
Jon Wm. Ezickson (USA)  has given a presentation with the title of "Deploying Innovation and Inventive Thinking in Organizations -- Applying TRIZ to Non-technical Fields of Business." The author is an accountant having about 200 businesses and individuals as the clients. Having studied TRIZ for these three, four years, he consult (small) business executives concerning accountancy/finance and is trying to introduce TRIZ in various business problems. Thus his paper is unique and practical. When he talks about businesses and their executives, he has in his mind many real instances of businesses and their executives.
Analyzing the current situation ofTRIZ penetration in industries, he shows the following figure of business organization. He says that even in (big) manufacturing companies only engineerign and research departments may be exposed to TRIZ and that the ignorance of TRIZ by executives and by other departments causes the difficulty in penetrating TRIZ company wide.
certainly the keypersons for promoting TRIZ across the
barriers of different business
departments/units. Senior managers are often aware of the
need and importance of innovation programs but more than half of them,
in some surveys, express disappointment to the finantial return of
innovation programs. The main reason for the failure of TRIZ in
getting appeal to executives is the mismatching, the author says,
between the TRIZ' engineering mind and executives' business
mind. He writes:
Then he discusses how to make deployment of TRIZ happen. He, as a consultant for promoting TRIZ, suggests how to write a formal business plan for the TRIZ promotion to be addressed to senior executives. He shows the contents of a formal business plan as: Executive summary; Financial analysis; Benefits, necessity, and advantages; Implementation plan; Performance measurement metrics; Historical and present assessment; Competitor analysis; and Organization, staffing, and mangement. (Though these may be trivial for some readers, they are instructive for me.)
The author also pointed out the necessity of integration of TRIZ with mangaement and quality programs, saying:
At the end of his paper, he mentioned on
some recent derivatives of TRIZ, including ASIT (Roni Horowitz), USIT
(Ed SIckafus and Toru Nakagawa), and UIT (Rodney King). He
pointed out the need of their education to reorient towards more
management and non-technical orientation. -- The author's
suggestion should apply to USIT most among these
three. The present author (i.e. Nakagawa) does not have
enough basis for extending USIT into business applications.
Collaboration in such a field is very welcome.
Graham Rawlinson(UK)  has given a presentation with the title of "(Exploring Issues and Ways of Dealing) Using TRIZ to Be (with Being) the Best Facilitator in the World". He writes in the abstract as:
If you use
TRIZ in groups then you will be leading a facilitation session, or you
will be training, or maybe both. Training in such a hands on
process such as being creative and getting innovative solutions is
anyway more like facilitating learning than teaching. Or it
There is a host of knowledge out there about ways of handling groups and this paper and session present some of the issues, soem ways of handling those issues, and offers a chance to have a dialogue about what you can do, should do, might do, mustn't do.
USA)  has given a presentation
with the title of "Using Lines
and Patterns of Evolution to Improve the Chances of Finding the Fuzzy Front End." Here, the word
'Fuzzy Front End' means any problem area that are not yet well
articulated and are full of ambiguity. In such a new field of
problem, human culture has been known to make progress very slowly in
the hindsight. Thus the author discusses how to apply TRIZ
concept of Trends of Evolution for accelerating the focusing on the
problem and finding any solution.
Miscellaneous / Concluding Remarks
After the dinner on second day (April 18), Boris Zlotin, a TRIZ Master, gave a talk. The Agenda announce it to be "A virtual tour of the Ford Museum through the eye of a TRIZ Master". Boris talked on his research history in the former USSR, talked about the concept of Resources, talked about Directed Evolution method, and talked about more and more. The talk started around 20:30, and I had to excuse myself for retiring to bed for recovering from jet lag at 23:00 while the talk was still going on some more.
Closing Session of the
Conference, Larry Smith (President of
Altshuller Institute) led a summary session of remarks from the
participants with the title of 'Liked' and then 'Would like'.
during the Conference it was exceptionally warm and fine. The
