基于原型理论的产品造型风格创新设计方法研究

目的 为解决产品造型风格创新设计过程中存在模糊性、不确定性和缺乏创新性等问题，提出应用原型理论思路从原型角度展开的产品造型风格创新设计。方法 首先基于感性意象对产品造型风格进行具象分类；其次运用设计形态分析结合离散度分析提取产品造型风格原型特征；再次通过联合分析获取产品造型要素权重从而确定关键风格原型特征；最后结合形状文法对产品造型风格进行创新设计。结果 以优雅型汽车前脸作为研究对象，设计方案在延续产品造型风格的基础上，继承和创新了部分形状特征，形成全新的汽车前脸。结论 设计方案的评估结果表明该方法在产品造型风格创新设计中的可行性和实用性。

Innovative Design Method of Product Modeling Style Based on Prototype Theory

In order to solve the problems of ambiguity, uncertainty and lack of innovation in the process of product modeling style innovation design, this paper conducts a study of innovative design methods for product styling from a prototype perspective based on prototype theory. By introducing the prototype theory approach, it provides guidance for the whole process of innovative design of product styling from a macro view. Firstly, product styling is classified based on perceptual imagery; Secondly, design morphology analysis is combined with dispersion analysis to extract prototypical features of product styling, and the weights of shape elements in product styling are analyzed through joint analysis to identify the prototypical features of key styles; Lastly, in combination with shape grammar, it carries out innovative design of product styling. Taking the elegant car front face as the research object, its design scheme inherited and innovated some of the shape features on the basis of the continuation of the product style, forming a brand new car front face. The evaluation result of the design scheme shows the feasibility and practicability of this method in the innovative design of product style.
