Simplifying TRIZ Inventive Standards (Part-3)

According to TRIZ most problems are “standard” problems. The standard problems are those which are known to have occurred many times in many places. Besides these problems have been solved by different people in different places (may be in different contexts) at different times. As there are many known solutions to such problems it is possible to abstract the rules of solution from the group of individual solutions. TRIZ provides a set of 76 rules to solve such standard problems. Although “Inventive Standards” (or standard solutions) is one of the most powerful techniques of TRIZ it is hardly used by any TRIZ practitioner because of its complexity. The objective of this series of articles is to explain the rules in simple language. Conventionally the solutions of Class-3 have never been presented with S-Field diagrams. The diagrams presented in this article are innovation of the author. If some TRIZniks don’t accept the correctness of these diagrams they are welcome to give their comments and suggestions.
