REVIEW OF THE AUGUST 2002 ISSUE OF THE TRIZ-JOURNAL

This issue of the TRIZ-journal represents a collection of various TRIZ perversions. To see it, let us consider them one by one.

TRIZ for dummies ?

The article by Nelly Kozyreva and Elena Novitskaya [1] proposes to teach TRIZ on toys inventions. The motivation is that toys are allegedly the only machines that are clear to everyone.

The authors seem to be unaware of the fact that any field of engineering has a plenty of inventions that are clear to any high-school student. There are even inventions which are clear to the junior-high school students. Altshuller taught TRIZ specifically on such examples. Do the authors want to teach TRIZ to people below the junior-high school level ? Then, I am afraid, the toys would not help them either. Because most of the authors' toys examples require some knowledge of mechanics.

The aim of teaching TRIZ to "dumb and dumber" is noble, of course, but, alas, not achievable with the current state of the art !

Microelectronics as a branch of mechanics ?

Turn now to the second article [2]. Its aim is to cast the microelectronics engineering techniques into the Procrustean bed of Altshuller 40 principles.

Again, the aim is taken at something dubious because the 40 principles include either the universal engineering paradigms (such as "fragmentation", "inversion", etc.) or the specifically mechanical engineering tricks (such as "counter-weight", "spheroidality", etc.).

Why does one need to search for microelectronics (or software engineering, or whatever else engineering) analogues to mechanical engineering tricks ? It seems unreasonable to me! One should create his own list of inventive principles specific to his own area of engineering and thereby augment the 40 principles and not to squeeze everything into them !

A random combination of unrelated concepts as a TRIZ article ?

Is it possible to generate a TRIZ article by randomly hitting keys of a key board ? Yes, of course ! Provided one randomly hits the keys for the time long enough. Then there is a non zero probability that a portion of the text thereby generated represents a TRIZ article.

This probability is extremely small and one may think that it can be increased by replacing the standard keyboard with one where keys represent not letters but some concepts and phrases from various areas of knowledge. Unfortunately, it is not the case. Moreover, such a keyboard may never produce a TRIZ article. It can only produce difficult to understand opuses containing combinations of not related phrases and concepts.

Nevertheless, it appears that Anja-Karina Pahl chose specifically the latter type of keyboard to generate article [3]. Dear Anja-Karina, you have a better chance of succeeding in writing something TRIZ related if you start combining letters rather than concepts.

Darrell Mann the dung-beetle

This issue of TRIZ-journal contains yet another article by Darrell Mann on contradiction matrix[4]. How many else is he going to produce ? - I am wondering. More than 30 years ago, Altshuller stopped working on it and decades later Darrell Mann came across this heap of TRIZ dung and marveled at it: "What a richness is hidden here !"

Ever since he continues to re-arrange the dung in one way or another. And always marvels:"What a richness, what a richness !..." Sometimes he adds his own dung to the heap or brings somebody else's. And continue re-arranging (adjusting, tuning - in his language).

Dear Darrell, leave it alone, move on ! There are so many other wonderful dung-hills in the world which are not the contradiction matrix and not the 40 principles !
