Research on Product Innovative Design Technology Based on Knowlege

With the development of Knowledge Economy, knowledge has become one of the key factors in new product competition. After knowledge-based product design researches abroad and at home are reviewed, a product innovative design and manufacture system structure based on knowledge is put forward,the factors related and key technologies are studied as well. In China western development, some suggestions such as extending the approaches of acquiring knowledge, setting up innovative design branch, implementing network-based design and concurrent engineering are proposed.
