| Industrial design for form, the most basic characteristics of morphology and essential external image, is a complex process. The difficulty in the design process can be divided into the following three types:aesthetics, structure and ergonomics. The structure design. which is built to a relationship between the positions of parts, is the key for carry out the functions of products better. Therefore, it is certainly important to solve the relation between people and object. The research and development of product, which have gone through the form follows function and internationalization period, begins introduce new subjects for more research in the relationship between product and human, which makes ergonomics, humanization and emotional factors become the new hot spots in industrial design.In the past, industrial design relied on industrial designer’s inspiration and creativity, which lead to the lack of rigorous and comprehensive analysis tools and standard. In this paper, we put toward the concept "units of feature", including three new methods in product design:the grid drawing, profile scanning for features and line-hunting method. The focus of research is to find an effective and strict method to control the whole design.The design method, which combines three-dimensional domain with element design, would provide a rational analysis in the form and contour of product for detail design. The grid drawing with point-searched is a method to change the product from three-dimension to two-dimension and get its orthographic view; then, the line-hunting method, a design method in analyzing the relationship of lines, would be used in the improvements to the form, the inner details and function modules. We would get the product’s contours through profile scanning. By analyzing them, we would find the line of centroid, which show the trend of product’s form, the functional modules and the active region. In order to improve the interaction between functional module and the human’s hand, the paper makes research on the movement of joint. The design method, on basis of three-dimensional domain and element design shows more reasonable and quantitative improvement in the design, of industrial products, which has a quite important meaning.The research encompasses several major topics:(1)The concept of the action domain and units of feature is used in the industrial design, through the analysis on the concept, characteristics of the role of product design and genetic model of the product design process, contact problems in product design, put forward two important research methods:human behavior domain and other element method, and discusses its concept and the basic theory content:the point, line, surface, body based feature design ideas, using the new design method to investigate the shape and the function of products, and illustrates the advantages of this method. (2) The paper puts the grid drawing with point-searched, which would build a product improvement platform. The method, with a rational product expression, show an conversion between two-dimensional and three-dimensional expression of the exchange relation:first, classify the line of product’s surface to get a deep understanding of the product structure; then, use the grid drawing with point-searched to get an axonometric drawing from the orthographic view. The paper would explain the specific implementation steps of the method and the tools and take an example to show the method of mouse.(3) The paper puts forward line-hunting method, which introduced the concept and characteristics of Bezier curve to classify product surface spline; line-hunting method provides for detailed design, through the lines of surface reversed shell line, the function module within the group of lines through the line classification definition, characteristics of product lines, the lines between groups of angle ratio and length ratio analysis, find the active area of line, and optimize the product line relationship.(4) The paper puts forward profile scanning for features. As an analysis method of product design, it starts from the analysis of visual dynamic product section scanning, then cross section morphology for each angle of existing products through the use of3D scanning, and statistical analysis with analysis software, analyze the product line features by scanning the edge means of numerical analysis. the analysis of section properties industrial design, to provide a set of feature based ergonomics. Scanning for features is proposed based on the concept of mass line, combined the steering wheel center with line extraction, analysis of fruit knife centroid line case, and explains the significance of product ergonomics.(5) The paper puts the action domain, which includes the concept of human behavior and product modeling boundary, and provides the initial platform for product design layout process. Relevant information model, serialization of product design model and dynamic process will make the whole design process dynamically. With solving the discordant relationship between people and objects, people and the environment, and the environment, it brings the mapping between the design parameters of human data and products for the first time, which takes the interaction to the early design process, and finish the space design that driven from the dimension to3D human body model.Through the research and exploration of the above-mentioned contents, the author hopes that the study results can provide a scientific basis for the industrial design, and lay a new foundation for the rational design in industrial design; meanwhile I hope to provide a new idea for the industrial designers for their further research. |
