TRIZ FOR THE DEVELOPMENT OF NEW MATERIALS: SOME PRELIMINARY IDEAS
To our knowledge,at the moment,despite some publications about TRIZ related to the field of materials science,TRIZ turns out to be poorly instrumental and very rarely applied for the development of new materials,which is the core field of materials science.The reasons for that situation are analyzed.It is recognized that a new material is an invention if at least one contradiction between its properties is resolved,and within the frame of Ashby diagrams,a quantitative approach allows to derive an objective criterion for such an invention,as well as a degree of invention,complementary to the qualitative level of invention by Altshuller.This quantitative approach can be applied to engineering systems as well.On the basis of the example of the famous dilemma between strength and ductility of metallic materials,it is shown that the structural strategies used by metallurgists to overcome the underlying contradiction match well with some known ways of resolving physical contradictions according to TRIZ.These findings fund the basis for a rough program the aim of which is the adaptation and development of TRIZ for the design of new materials.
