产品族关键造型要素提取与差异化定位方法

Key modelling element extraction and differentiated positioning method of product family

为避免产品族造型设计过程中目标特征定位模糊导致的用户群需求冲突问题,提出了一种产品族关键造型要素提取与差异化定位方法(Key Modelling Element Extraction and Differentiated Positioning Method,KMEE-DPM)。通过因子分析法提取了产品族感性意象因子;采用全局HIEs法获取了产品族造型设计要素及设计特征;基于数量化理论Ⅰ分析感性意象与设计特征间的映射关系,结合感性需求分析确定产品族造型设计的目标特征;用k-means算法解耦目标特征,基于解耦结果提取关键设计要素并得出其应用策略,实现目标特征的差异化定位。以城郊多用途汽车(Suburban Utility Vehicle,SUV)内饰造型设计为例进行验证,KMEE-DPM能有效提取SUV产品族内饰造型的关键设计要素并实现差异化设计定位,同时输出的设计方案能够满足目标用户群的个性化需求和多用户群的共性需求,有效避免了用户群需求冲突问题,证明了KMEE-DPM具有一定的实用性和有效性。

In order to avoid the user group demand conflict caused by fuzzy target feature positioning in the process of product family modelling design,a key modelling element extraction and differentiated positioning method(KMEE-DPM)for product family was proposed.The perceptual image factors of product family were extracted by factor analysis;The design elements and design features of product family were obtainedthrough the Global HIEs method;Based on quantitative theoryⅠ,the mapping relationship between perceptual image and design features was analyzed,and the target features of product family modelling design were determined combined with perceptual demand analysis;The k-means algorithm was used to decouple the target features,the key design elements were extractedbased on the decoupling resultsand the application strategies ofdesign elements were obtained to realize the differential positioning of target features.Taking the interior modelling design of suburban utility vehicles(SUVs)as an example for verification,KMEE-DPM can effectively extract keymodelling design elements of SUV product familyand achieve differentiated design positioning.The output design scheme can meet the personalized needs of the target user group and the common needs of multiple user groups,effectively avoiding the problem of conflicting user group needs,proving the practicality and effectiveness of KMEE-DPM.
