Abstract: In order to excavate products evolution characteristic information more effectively and conduct product innovative design more quickly, a product innovative design method based on endogenous function requirements was put forward. Models for the existing products were set up by introducing system function analysis method. From the three perspectives of super system component function correlation, single-component function change within the system, and multi-component function combination within the system, an all-over creative expanding was conducted by using the analysis strategies and tools as function matrices, function trimming, function combination, et al. Aiming at the function requirement information produced by incentives, concept solution and analysis of domain specific were conducted, then the final product improved solution was generated. Based on the creative application process of the incentive model, design function modules in prototype system were developed. An example of the improved design of fridge freezer was used to prove the validity and practicability of the method.
