The new method to define ideality on triz

Abstract

Contradictory matrix and Ideality are the very important concepts of TRIZ-Theory. Generally, Ideality is defined as the ratio of useful function and harmful function. But, how to define "function", and how to differentiate the useful function and harmful function, has not confirmed yet. This thesis uses 48 parameters to redefine function, and then provides the formula of the Ideality of technology system. Furthermore, it puts forward a guess of the curve based on the increment of Ideality, which could provide the reference value for the evaluation of the new technology. © 2013 Springer-Verlag Berlin Heidelberg.
