research on function structure inverse solving method of design history based on s-s-e-f mapping

Most enterprises have deficiencies in the information management of available product design history, which causes unable to directly identify the corresponding relation between structure and function, so the true local demand-varying design can't be really realized. To rapidly and efficiently solve the local demand-varying design, this study proposes the use of Structure-Solution-Effect-Function (S-S-E-F) mapping-based inverse method to solve the function structure of design history. The function structure of design history is obtained by constructing the inverse solving model of design history based on S-S-E-F mapping, then capture product design intent information .Moreover, the feasibility of the proposed method is verified by analyzing the function structure of forklift drive axle as an example.
