Question № 45 date : 07/29/2010/ 09:19:22

hello, i want to get a TRIZ certification, i learn function analysis, solving problem with contradiction matrix, utilisation of smart small people, trend of evolution and the 40 inventive principles with Darell Mann book, and triz formation of ENIM ( engineer school of Metz) and i would know if i have to begin the formation in elementary or basic knowledge? Charlie Lutaud

Dear, Mr. Charlie Lutaud,

All that you have listed is only sketchy knowledge on TRIZ and near TRIZ techniques. The SYSTEM of knowledge on TRIZ is necessary for you. It needs regular training. For example, on our e-learning course.

Regards,
Dr.Y.Salamatov

Question № 44 date : 06/07/2010/ 06:07:44

Dear Dr. Salamatov:
I am a student of Southwest Jiaotong University, which is located in Sichuan, China. Now I am reading your book titled "TRIZ: The right solution at the right time"(Second Edition, 2005), and I am very interested in it. However, there are some questions in it which I colud not answer to myself:
One of them is: what is the specific solution to Problem 10, i.e. how can we "
providing a normal hardening process at no extra pressure"?

S: This is only an example of the typical problem (30 years ago). I do not know the solution. I am fully with confident that it is solved and the technical contradiction is resolved. It is necessary to view the chapter (metal hardening by laser beam in nitrogen atmosfere) in patent data base of Russia or USPTO.

Another one is why do you think "In fact, technical contradiction may not emerge when we are synthesizing a technical system (completion of S-Field model), for nothing prevents the inventor from introducing the missing elements into the system. This is the only case when inventive problems are solved without technical contradictions. As for the rest of cases of technical system synthesis (when conditions of the problem contain restrictions), technical contradiction will always be there." in the beginning of Chapter 3?

S: It is absolutely always this way!

Is there any "inventive" situation where no technical contradiction have been eliminated?

S: Of course and there are many such problems. These problems are on the front of the science and engineering. Somebody (an inventor) planning to create new (innovative) technical system, formulating which functions should be (how TS correlate with human-society needs), trying to find physical-chemical-geometrical effect in science (for the contradiction resolving) and… does not finding it. There is no such effect! And this is very important assertion. This is social order for science to find out such effect, carry out research and formulate science problem.

And the last questions, which is related to the second question, is:
"The fourth level (mor§е than 103 – 104 attempts): macro inventions. It’s a synthesis of a new technical system. As it doesn’t contain any technical contradictions, one may think that their elimination didn’t come into making these inventions. In fact there was a technical contradiction, but it existed in the father technical system. In the fourth level problems the contradictions are eliminated using methods belonging to another field of science (e.g., a problem in mechanics is solved using the principles of chemistry). Quite often a newly found principle helps to solve a lot of other second and third-level problems (for example, the use of magnetic fluid)."in 4.2 of Chapter 4. Could you please take an example of "a technical contradiction……existed in the father technical system"? Thanks a lot!

Let’s consider an example. At tests of the engine of internal combustion (EIC) periodically it is necessary to measure deterioration of its details, therefore in 50th years of 20 century a standard on definition of metal particles in oil was accepted. For this purpose they take the test of the oil and define the contents of metal particles in them by chemical method. The analysis takes approximately 1 hour. At EIC creation for the racing car engines working on extremely modes this way appeared unacceptable. For this time EIC "will run" 200-250 km. It is too much to define the critical moment of the destruction beginning of EIC details precisely. How to be? TC: for definition of the moment of the destruction beginning of EIC details it is necessary to carry out the analysis of oil on presence of metal particles, but it cannot be made at the moment of the destruction beginning (1-10 seconds), since the analysis takes 1 hour. I.e. the analysis of the metal content should be continuous, and existing method has the period 1 hour. TC resolution: a phosphor (luminophor) adds in oil and fine particles of metal extinguish a luminescence of the phosphor. It continuously allows supervising the metal content in oil.

I speak about triz with everybody , all of them aske me a similar question , what is triz benefits for me ? for example one of my friends study international marketing ? how can I answer about his question about triz benefits for him ? really what is triz benefits for marketing ?

Any training gives something to the person: an occupation, new knowledge, skills, working methods. Marketing training gives new knowledge but not changes the thinking. TRIZ - is unique tool today for change of trivial (stereotyped) thinking onto innovative one. Such change of thinking we always observe at trained engineers. It comes not so quickly, approximately after 12 months of training. The person having innovational thinking views the world around as another one; he boldly begin to solve any inventive problem; he understands, that there are no not solved problems. The person having innovational thinking has a great value for companies aimed on innovational development and he is not necessary for out-of-date (backward) companies.

Question № 42 date : 08/09/2009/ 19:55:23

From: Persian Designer I have a CD that there is the archive of triz- journal website. There is in February 2002 an article: Assessing the accuracy of the contradiction Matrix for recent Mechanical inventions . Can I do such this article in iran ? collect a bank of inventions and analyse them on triz ? if it is useful what is its benefits for me ?

Altshuller's matrix is the outdated TRIZ tool of inventive problem solving. It is not necessary to develop it. Such article you can write, it is not prohibetted.

Question № 41 date : 07/03/2009/ 06:56:10

Dear, I am trying to study ARIZ 85 and someone pass me this problem about movil phones: There are antique movil telephones that transfer only latin words.In some foreign countries there are laws that request that mesages only can be transmitted in national alphabets.But this national alphabets require more words than the latin alphabet. So you need the necesary memory to contain this foreign alphabets that are not present in this antiques movil phones.But to add memory is expensive. So you need “the change without a change”. The company needs to sell antiques movil phones but it is not posible not to comply with the law.So the antique phone must transfer all written mesages in any alphabet. Adittional info: the antique phones uses a pack of eight elements for the record of each letter.The pack quantity is equal to the quantity of the latin alphabet. Also there is a limit of memory for the packs quantity of those movil phones. It is imposible to change this. Have you the complete ARZ 85 solution so I can study it. Oscar Isoba Argentina

There is no solution of this problem. Certainly the physical contradiction resolving should be at a system level (system: alphabets+pack+memory).

Question № 40 date : 07/02/2009/ 19:19:56

Will you be interested in visiting different countries to conduct day classes for group of participants of 25? Your stay may last one to two weeks at a time.

Our main purpose is innovative projects. Training is additional business.
Therefore individual distance learning is preferable. It is modern, effective and convenient for the person and managers of personnel.
Study can be added by online videoconferences (express-consultations on the final work theme,
answer on questions. Exit seminars are possible in exceptional cases with higher payment.
What about 1-2 weeks seminars do you speak? TRIZ is impossible to study within 1-2 week (6 hours per day).
It can be only introductory lectures and trial (base, demonstration) trainings on TRIZ. During this time does not occur thinking change (usually it requires 1 year). Therefore after this training it is necessary to train 6-9 months remotely (distantly) obligatory.
Seminar with duration 1 week (6 hour per day) shortens distance learning on 2-3 months (with the condition that the person will spent else 2-4 hours on home tasks making daily. It is hard routine. At this the seminar with the duration 2 week adds
fatigue but not add the thinking change. If manager of personnel does not understand (not see) benefit of distance learning, then it is possible to offer symbiosis of "live" and distance learning:
1st stage - introductory seminar 1 week (days х 6 hours = 30 hours), 1000 euro for each person plus charges of train and living for 2 persons.
2nd stage - distance learning - 6 months with the program on our site http://triz-guide.com/learning_course.html.
3rd stage (for advanced Customers; for our understanding is not obligatory) - final 3 days seminar with the review of pupil's solutions on problems of home tasks (typical mistakes and the methods of its overcoming), final works defend, creative abilities estimation of all persons with rating definition (digital estimation), creative portrait creation for each person (special document with person's photo from IID - the abilities analysis), certificates handling and mini-banquet. The payment is as on the 1st level.

Question № 39 date : 04/30/2009/ 08:15:59

I am still struggling a little bit with one of the fundaments in TRIZ: the main useful function. What is actually the best way to identify the main useful function of a system? As an example a wind turbine and its subsystems the nacelle, tower and wind blades. What are the MUF of the system and the MUF of its different subsystems? Could you reply on this please? I am mainly confusing the goal with the MUF of a system I am afraid.

MUF of systems - to execute the requirement (desire) of higher rank system (the first from a rank of this system).
The second rule: if mentally to remove any element of system, then MUF will not be carried out (that means MUF is correctly formulated).
Example: wind power station (WPS) - not the wind turbine, but whole system.
WPS MUF - to give the energy to the person (to transform a wind power into electric one). Remove any element (blades, transmission, the generator,
etc.) and MUF will not be carried out.
Blades MUF (propeller): to catch (to take) mechanical energy of moving air.
Transmissions MUF: to transfer mechanical energy from a propeller into a shaft of the generator.
Generator MUF: to transform mechanical energy of rotor rotation into electrical one.
Weathercock MUF: to turn a propeller towards to a wind.
Frame MUF: to keep elements of WPS in given
constant position. Accumulator MUF: to accumulate electric energy.
Etc.
