Abstract


Product design is an innovative design, product form, color, material, texture (or decorative) several styling elements according to certain requirements of the optimal combination of process, plays a very important role in modern product innovation and development process. It involves the design psychology, cognitive psychology, artificial intelligence, engineering, science, ergonomics and other related disciplines, including image and logical thinking. Therefore, the combination of these disciplines the digital intelligent product design system development has become one of the hot spots of the new research in the field of product design. In this paper, based on analysis of the computer-aided industrial products, innovative design and case-based reasoning (CBR) status quo, build a product modeling system framework, product modeling elements (shape, color, material, texture) information database system; application of Kansei Engineering is recognized knowledge of psychological theory and methods, research-based information product image styling elements to construct the user of the product shape image evaluation model; evaluation information on the sample product modeling imagery factor analysis and principal component analysis of its results build products technology development of the method of the shape of the image space; application of the ASP, SQL Server, Dreamweaver Web-based product modeling image repository system; application of factor analysis and principal component analysis methods imagery information processing to filter out a certain amount of imagery vocabulary build a specific product styling elements corresponding image space; styling elements of the product, the product overall styling and users of the product shape image semantic analysis, and application information to establish the corresponding BP network model, as genetic fitness function of the algorithm in the case of products based on genetic optimization product modeling program, to get more in line with user needs; shape innovative design of electric vehicles, for example, the styling elements of the electric car in the form of decomposition outline components, connected relationship, detail treatment given the morphological characteristics of the electric vehicle line method to build electric cars morphological elements of the sample library; production samples of colors, materials and textures in the electric car styling elements. The effectiveness of the improved design of electric vehicles instance modeling to verify product modeling, innovative design, the development of product modeling image repository system.
