Design Theories Analysis in Frame of the Definition of Inventive Design Efficiency
This paper represents partial results of our research among different design theories to make a data base of the theories components, discern inventive design activities and define an indicator for inventive design efficiency. Components that have been found and listed in this paper are in association with three approaches as C-K theory, FBS framework and TRIZ theory. Despite these three approaches have totally different structures and have been defined for different missions and applications, but comparatively against the others trace the evolution of concept during design acts and try to reformulate the originality degree of new product. This last steer us proposing a new inventiveness metric model as a combinative preliminary inventiveness assessment which is based on the three mentioned design approaches. This integrated inventiveness assessment model is represented in third section.
