This method is still under construction.TRIZ is an acronym for the Russian: "theory of the resolution of invention-related tasks". TRIZ was initially developed by the Soviet inventor Genrich Altshuller (1926-1998) and his colleagues in 1946. Since then many researchers and private firms have expanded on this original research and have developed online TRIZ databases over thousands of patents in a wide range of fields. The basic idea is that technological systems evolve over time to overcome apparent contradictions. The TRIZ matrix highlights 40 principles that have overcome these contradictions in the past. Online TRIZ databases allow designers to type in functional contradictions and receive suggestions for the most relevant principles that might give strategic approaches to overcoming the contradictions. The classic example is how to make a product that is strong AND light weight. This is an apparent contradiction as we tend to think that we must add more mass to make a product stronger. TRIZ would suggest the following for principles in order of their relevance for how this problem has been solved in the past. 40 Composites: Change from uniform to composite (multiple) materials. 26 Copy: Instead of an unavailable, expensive, fragile object, use simpler and inexpensive copies. 27 Cheap, Disposable: Replace an inexpensive object with a multiple of inexpensive objects, comprising certain qualities (such as service life, for instance)1 Segmentation: Divide an object into parts or increase the degree of fragmentation or segmentation.
