Special user presentation:
“How we did apply TRIZ at Samsung”
Samsung Advanced Institute of Technology
Applying TRIZ at Company (215KB)

During 3 months, [of observing TRIZ consultants] ‘he’ could see successful consulting result. Field engineer and researcher [were] satisfied [with] the provided ideas. But ‘he’ could not find any trace of using TRIZ. ‘He’ thought, “If I had enough experience of consulting during 30 years, too, I could also generate such an idea. During three months, I could not see any trace of using 40 principles or Su-Field Analysis or 76 standard solutions or ARIZ. There is no TRIZ.”
After long enough time had passed, I could not help recognizing them as a TRIZ expert. “However clever they are with great experience, it is impossible for human to generate such m any ideas of good quality in such a short time without any methodology. In TRIZ, there must be something special which I don’t know.”
During last 3 years, their TRIZ team did successful consulting activities. The economic benefit after applying TRIZ ideas is impossible to count (more than 1 billion US$). But they did also build systematic infrastructure about TRIZ.
– Formalized TRIZ consulting process
– Systematic and attractive Education course
– Research about TRIZ
– As a result, deeper understanding of TRIZ ability
– TRIZ user meeting
In any situation of a TRIZ team at a company, 4 things are necessary for surviving:
1. Calculated benefit money from mass production line every two months
2. Breakthrough patent from research field every half a year
3. Systematic and practical education course
4. Deep understanding and research about TRIZ
For #1 and #2, it could be done by Russian TRIZ experts at the initial stage of the TRIZ activity. But the IFR (Ideal Final Result) of TRIZ activity at a company is “TRIZ can be applied directly into research and development team without the help of the TRIZ team”. For such a reason, #3 is a critical point. But without #4, #3 is absolutely impossible. #3 and #4 are difficult problems. Almost such difficult problems usually have more than one contradiction.
At #3, there was the following contradiction: Education course must be short at the company. But it must be long enough to understand TRIZ. Usually, TRIZ is recognized as the most difficult methodology to understand and apply it on real fields after learning.
At #4, there is another contradiction: TRIZ understanding must be simple, because almost all the great theories are simple after understanding. A good example is thermodynamics. But it seems that there are too many tools in TRIZ. Sometimes it is too difficult to understand the co-relation between various tools of TRIZ and organize the right order of action. It’s another contradiction for solving real problems using these tools in a short time.
At this presentation, some solutions to such contradictions are provided. The presentation will be based on practical experience for successful TRIZ applying, not theoretical.
“Best Practices of TRIZ at Samsung – DVD pickup, refrigerator, PDP, etc.”

Samsung Advanced Institute of Technology
Decreasing Cost of DVD Pickup (157KB)
Increasing Efficiency of PDP
Refrigerate – “Zipel”
Patent Avoiding – Washing Machine
Technology Evolution – From the Point of TRIZ View
Technology Evolution Diagram – Display System

Two years ago, a company tried to save the cost of DVD player pickup.
Until that time, the competitor company’s cost was 21 US$, and that company’s cost was 11.7 US$. Of course, the difference was big, but that company wanted to save more, because the DVD market was emerging with great speed and China’s attack has started with extremely low price.
DVD pickup d evelopment team invited Russian TRIZ experts to decrease the cost of DVD pickup. They had to change the design although they were not experts in optics field. Fortunately, there was a young Russian optics engineer in that team.
After 5 months consulting, they developed a new design of DVD pickup. This design was beyond the mental inertia of a usual optics engineer. Cost was decreased from 11.7 US$ to 7.0 US$ and that design has become the basic platform at this company now. Every year that company produces more than 5 million DVD players. If the DVD pickup at a computer system is considered, more than 10 million pickup modules are produced every year. This development was called Sellino project.
Expensive side-by-side type refrigerator usually has a ‘home-bar’ at the front door panel. This home-bar was designed to fold and open with the right angle. For this purpose, they used link bars made of stainless steel at two edge sides. The competitor company used 2 stainless steel bars with moving end parts, which was the patent of GE. So, this company used 4 stainless steel bars with fixed end parts and a joint between the two steel bars. As stainless steel bar is made of expensive metal, they wanted to decrease the cost.
So they asked the TRIZ experts to solve such a cost reduction problem.
The TRIZ experts provided IFR (Ideal Final Result) with ‘zero’ cost instead of reduced cost. The new home-bar structure doesn’t use steel bars at all, and customers even can enjoy a more convenient home-bar. TRIZ always wanted to provide ‘Breakthrough Ideas’, and not compromising ones.
In the PDP industry, the efficiency is the most critical point, and now an advanced PDP in the market has an efficiency value of 1.8[lm/w] . Whereas, this company had 1.5 [lm/w] . They requested TRIZ experts’ consulting for another new idea of increasing the efficiency, because they already have done their best and could not wait another long time for good ideas.
TRIZ experts provided three main ideas. One idea has already been adopted and finished e xperiment. This new design will be applied to the market early next year. The second idea will be tested this year. This one will change every PDP display structure if the experiment result is good. PDP engineers are expecting more than 2[lm/w] with just a simple change. Everybody will think, “Why couldn’t I think of such a simple and powerful design?” Usually, almost all the great inventions are like a
“Columbus’s Egg.”
The last idea deals with barrier panel structure and manufacturing. This idea will be tested next year. TRIZ experts are expecting an increase of efficiency by two times. Via such actions, that company is keeping continuous initiative for breakthrough at the market.

User presentation:
”Education Practice Using TRIZ for Bringing Up Creation Development Type Engineers”
Nagano National College of Technology,
Department of Mechanical Engineering
National technical junior colleges are engaged in engineering education aiming at upbringing practical engineers, and have been conducting “Manufacturing” education.
This time, it was tried to introduce TechOptimizer, a support software utilizing TRIZ, in order to practice education for learning an idea and creation method that brings forth something non-conventional and entirely new, instead of just acquiring knowledge and skills to make things.
The results of “Creation Engineering Training” given to fourth graders at Department of Mechanical Engineering in Nagano National College of Technology are reported.
”Current Status of TRIZ Deployment at Nissan Motor Co., Ltd.”
Intellectual Property Department
(Part 1)

The background of TRIZ adoption and representative activities including in-house education from the early period to the present is introduced. (Part 2)
Concrete case studies like “How to deploy”, “How to acquire basic knowledge”, “How to master software operation”, etc. is introduced based on the experience of the presenter himself issuing a guideline for accomplishing tasks as a person in charge of TRIZ for the first time.
In addition, useful things for a beginner from information such as the many books and web sites on TRIZ is brought up to give an indication of the knowledge level that is necessary for a beginner to carry out TRIZ promotion activities.
”Improvement of Recycling-oriented Eco-friendly Packaging”
Ricoh Company, Ltd.,
Imaging Technology Division
The in-house education of TRIZ at Ricoh has been firmly established.
In response to expectations from the promotional side to get results, this presentation is a case study on the circulation type eco-packing th at an attendant at an internal TRIZ education lecture approached with his own problem.
The circulation type eco-packing, which is one of the environmental management of the Ricoh Group, was first introduced in 2001 centering on the metropolitan area, and developed to regional expansion, broadening of target models and addition of recycling items in 2002.
The problem taken up here originated with the addition of a recycling item, a part called “strap”, which was regarded as a disposable within the circulation type eco-packing of the former model.
The reason why this problem appeared on the market even it was sent out with confidence after enough evaluation, and what should have been done is analyzed utilizing TRIZ.

Special lecture:
”New Understanding of TRIZ Entering the Steady Introductory Period”
Osaka Gakuin University,
Faculty of Informatics
Now, the introduction of TRIZ into the Japanese companies exceeds gradual introduction (Slow-but-Steady Strategy) and it seems that it has entered the stage where the steady introduction (Steady Strategy) is possible (and appropriate).
The reason for this is that the understanding of TRIZ itself has grown up to an understanding in the Western and Japanese society from the introduction of understanding in the former Soviet Union, and that it has entered a stage where it is known broadly.
The following items shows these new understandings:
1. TRIZ textbook “Hands-On Systematic Innovation” (translation into Japanese in progress) by Darrell Mann
2. Modernization of TRIZ by their analysis of an American patents (new “contradiction matrix”, etc.)
3. Text book “Breakthrough Thinking” by Larry Ball
4. A system of solution generation method of USIT in Japan
Steady fixation at companies has become possible by deeply understanding and practicing “digested” TRIZ.
