Parametric Design Of Products Based On Kansei Engineering

The powerful logical operation and digital graphic evolution ability of parameterization technology bring new design sources for the traditional product modeling design,and its high efficiency and real-time also become one of the most extensive computer-aided design technologies today.With the increase of values in the perceptual age,perceptual transmission in products has become an important factor affecting consumer consumption.However,parametric design ignores the emotion of consumers due to the rationality of number.Therefore,the perceptual expression of product parametric design has become a hot topic at present and in the future.This topic is proposed based on perceptual product parametric design methodology of the theory of technology,by using the perceptual experiment,mathematical statistics and analysis,shape grammar,the study of the theory of the parameterized,etc,to build to response the perceptual demand of product design system,drive in the parametric design modelling accord with consumer products perceptual image.The system is composed of three parts: the first part is to extract the perceptual data of the product,obtain the data of the product characteristics and the mapping model,establish the perceptual database,and provide data for the product parametric design system;In the second part,the perceptual database data is combined with the shape grammar theory to generate a large number of feature genes to build a gene bank,and the parametric modeling logic is constructed to complete the modeling assembly output design scheme.The third part is the platform construction of product parametric design,through the platform to assist designers in product design,the output design scheme can also meet the inner emotional image of consumers.
