A Computer Aided Innovation (CAI) system was constructed for the New Product
Development (NPD) engineers of Guidance, Navigation and Control (GNC) precision complex
product, which consists of two modules, namely, Knowledge Management (KM) module and
innovation process module. KM module was used to manage internal knowledge of enterprise, and
innovation process module provides innovation principles and methods for R&D engineer. The
whole CAI system was constructed to utilize the internal and external knowledge effectively, also to
bring a structured process for problem-identification, problem-solving and solution-generating
during NPD process. At last, an engineering application example demonstrates this system can
provide innovation support for GNC product.
