ABSTRACT
The patents fund analysis shows that a relatively small number of generic rules of thumb or heuristics is used over and over in originating, developing, and applying for improvement of parameters of various techniques. Each heuristic is usually not confined to a single scientific rule but incorporates several laws of physics, chemistry, or engineering. Consideration of these heuristics is valuable to the inventor because of the generalized and concise survey of present day science and engineering they afford. TRIZ provides detailed recommendations and instructions which allow inventors to use these heuristics effectively. This section provides detailed discussion of various heuristics recognized in TRIZ and instruments built on them. It consists of six chapters, the first of which deals with heuristics for pair contradictions. The heuristics for point contradictions and the Standards are discussed in Chapters 14 and 15. As Appendix 6 shows, these heuristics are not independent of each other. Nevertheless, the “artificial” division of heuristics used here is useful during studies of TRIZ.
