Research On Design Method Based On Feature Lines

In condition of taking the consumer as the guidance of market, when designer carries on a design process, often information of several aspects factors, like the product itself,the corporation,the market and the consumer must be put together for synthetical consideration, analysis and reorganization, finally manifests on the design product. Among these information, product's self contained information is often described by quantitative means,while the rest are described by the qualitative means. Only if the combination of these two description is found, can designer sleaves their thoughtway, and systematically grasps this series of information.The paper based on the system theory design ideology as foundation, using the knowledge of Product Semantics and Computer Aided Design, and by dint of the research method of Kansei Engineering to discuss the problem of how to combine the information of quantitative description and the information of qualitative description to design,and research the method based on feature lines.Firstly, the paper researches the modeled principle and the description fashion of feature, brings forward the principle which looking on the feature lines as the bridge to connect the information describe by quantitative means and qualitative means. And according to the principle of"primary global precedence", we plot out the feature lines to 2 kinds. They are the feature line which affecting prophase attention and the feature line which affecting anaphase attention.Secondly, the paper discusses the relationship between feature line and people's attention, and the relationship between feature line and sensorial description.Finally the paper analyses how to use the feature line to direct design during the process of establishing the projects and the three-dimensional electronic models in the program of product design. And by the analysis of my own design work, the paper summarized the common design methods based on feature line in different type of design assignment of product exploitation.
