The Interactive Evolutionary Design Method Of Handheld Detector Styling

With the rapid development of China's economy,science and technology,market competition has become more and more fierce.Consumers pay more attention to the uniqueness and aesthetics of product and used them as an important reference factor,but not only been limited to quality and cost performance.A good product model can not only satisfy the consumers' image perception and demand,but also help enterprises enhance market competitiveness.Traditional product design relies mainly on the subjective experience and the knowledge of designers,lacking of consumers' participation,so the objectivity of the design results is limited.This paper brings the biological genetic thought to the field of industrial design,and proposes a two-layer genetic algorithm to design the handheld detector model,quantifying the product form.Besides,it uses computer-aided design technology to realize shape optimization,modeling and color scheme.In general,it uses the interaction feedback with the user to finally generate a handheld detector shape with uniqueness and aesthetics.The research is mainly divided into three parts:The first part is the establishment and optimization of the handheld detector outline.The handheld detector outline is extracted from the sketch by two-dimensional plane software;The contour is drawn by two different stages of Bezier curves,and the curve control points and curvature control points are defined as morphological design variables;The continuous level of the curve establishes the relationship between the morphological and the variables;Starting from the functional design space,the ergonomic design space and the modeling trend space,the variable threshold is imposed on the morphological design variables;The fitness function is established based on the user's requirements,and the MATLAB genetic algorithm optimization tool is utilized.The box is genetically optimized to finally obtain the optimal hand-held detector outline that meets the conditions.The second part is the details of the handheld detector design.Through the module division and the summarize of functional requirements,the detailed design elements are listed;The typical images of the relevant modeling products are collected according to the network,and the detailed design elements are extracted to form a scheme library of hand-held detector modeling details design elements,and it will be made in the two-dimensional software.It is drawn out by using the combination innovation method,and the detailed elements in the program library are arranged and combined to generate a modeling scheme;The AHP method is used to calculate the weight of the hand-held detector modeling evaluation item,and the appropriate crowd is selected to score and calculate the modeling scheme,and finally turn out the satisfied handheld tester styling solution.The third part is the color matching design of the handheld detector.Based on the Core|draw development platform,the interactive genetic algorithm is combined with the product color matching to establish a product interactive genetic color matching system;Then,the system is used to match the color of the handheld detector design scheme,and finally the handheld tester formula scheme satisfactory to the target user is obtained.
