For overcoming the limitations of traditional computer aided design platform, a framework of the Internet-based intensive product design platform (IPDP) is proposed. The structure of IPDP and the key issues regarding its implementation are introduced. Further, the mean of knowledge storage, acquisition, and representation are portrayed in detail. Based on the concept of function driven, connected artificial neural networks and active server pages techniques, a novel method of knowledge search over the Internet is achieved. Finally, a prototype to demonstrate the feasibility of the structure and the constructional method of IPDP is developed.
