基于风格进化模型的产品生成设计方法

针对产品风格进化现象与创新设计问题,提出了产品风格历时性与共时性进化模型.在该模型基础上,结合生物遗传学理论定义产品风格基因.以典型汽车产品风格为例,在引入造型参数化表征前提下,运用主成分分析进行参数规约,并利用形状文法实现风格基因表达.然后,建立基于遗传算法的生成设计机制,该机制采用正交分析的策略来精简初始种群规模,通过适应度函数实现方案收敛.最后,开发出面向汽车产品的风格生成设计系统,并验证其有效性和实用性.风格进化规律、风格基因建模方法及创新设计技术对于动漫设计、平面设计、服装设计等领域研究也具有指导或借鉴作用.

Method of product generative design based on style evolution model

Aiming at the style evolution phenomenon and the creative design problem,a product style diachronic and synchronic evolutionary mode is developed,and the product style gene is defined according to the theory of biological genetics.Specifically taking the typical automotive style as an example,the shape features are extracted and introduced as the form of parameter,which are dealt with the principal component analysis and the style genes are expressed with shape grammar.Further,the generative design mechanism based on genetic algorithm is constructed,which applies the orthogonal analysis to simplify the initial population size,and the convergence is achieved with the fitness function.Finally,the generative design system for automotive style is advanced and the effectiveness and practicality are verified.The research will have important and directive significance to enrich and expand the application in many fields such as architectural design,interaction design,fashion design,etc.
