Research On Product Form Design Technology Based On Knowledge

Human design thinking is a complicated process of recognition, which contains many psychological factors. Design process is not a static state, whereas it manages all kinds of knowledge and technology. The design activity, in fact, is a process that the designer represents users' demands and his conceits with his design language, and that user knowledge and design knowledge interact and couple with each other. Therefore, it is significant to study the forming process of design knowledge and put it in computer simulation.In this paper, searching technology of product information based on knowledge was researched. On the aspect of cognition, we researched the relation between user's cognition and designer's cognition, explored the knowledge flow in the process of product development, set up a matching model between user's knowledge and designer's knowledge, brought forward a modeling method based on users' cognition, and set up a measurable model of product feature; coded and decoded product form element, set up a computer aided product form design system and image evaluating system based on the result of measurement. Accordingly, the product style and product image were systematically discussed, the recognition space of product style and image was constructed, the factors that affect product style and image were put forwards and analyzed, and the relation between product image and form elements was tested by experiments. Furthermore, the product automatic recognition technologies were discussed.And then, with the media of concept model and the kernel of parameter technology, a mathematic model that describing product layout design by constraints and rules was presented. Furthermore, a product design integration system based on imagery thinking including product fonii base system based on imagery thinking, product form design system based on imagery thinking and product form intelligent design system based on space layout were set up, which tested the system and provided a new way for product innovative design.
