概念衍生中产品案例视觉表征风格转化研究

Visual Representation Style Transformation of Product Form Example during Design Ideation

目的探索利用产品造型案例的视觉表征风格转化刺激设计概念衍生的方法。方法借助卷积神经网络算法从经典设计草图中提取视觉风格特征,并以此为基础对案例照片进行视觉表征风格转化处理。通过对比实验,组织设计者分别运用原始案例及风格转化处理后的案例进行快速概念设计,利用配对t检验分析两次实验的差异,结合实验后的访谈,确定风格转化处理对于设计概念衍生的意义。结果与原始案例相比,风格转化处理后的案例更能吸引被试与之进行互动,并且设计输出的数量和质量都有了显著的提高。结论利用经典设计草图中的视觉风格对案例照片进行风格转化处理,能保留和强化案例的关键设计要素和形态特征,同时去除不必要的干扰信息,对设计者提取设计知识、扩展设计思维、避免设计固化具有一定意义。

The work aims to discuss the method of applying visual representation style transformation of product form design example to stimulate design ideation.Visual style characteristics were extracted from the classic design sketch through Convolutional Neural Networks,on the basis of which the visual representation style transformation was carried out to the example photograph.Through contrast experiments,designers were organized to achieve rapid conceptual design based on the original example and the example after style transformation respectively.The difference in two experiements was analyzed by paired t-test.Combined with the interviews after the experiments,the significance of style transformation on design ideation was determined.In comparison with the original example,the design example after style transformation succeeded in appealing to more interactions of participants and improving both quality and quantity of the design output.Style transformation of example photograph by visual characteristics in classic design sketch can preserve and further reinforce pivotal design elements and morphological characteristics in design example while excluding from unnecessary interference information,which is of certain significance for extracting design knowledge,broadening design thinking and averting design fixation.
