产品形式和美学在消费者偏好和产品差异化中发挥着重要作用。在产品系列设计过程中，区分系列中的产品非常重要，但某些风格特征之间的相似性可能意味着更连贯的设计策略。形状语法提供了一种生成具有连贯风格的设计的方法，并且能够控制输出形状的变化。在本文中，我们研究了使用形状语法来支持产品系列设计，即识别塑造系列内相似性感知的特征。实施基于调查的方法，其中通过将设计变体与基线设计进行比较来评估形状参数对产品风格的影响。受访者被要求以类李克特量表对风格相似性进行评分，并使用分数阶乘实验筛选候选形状参数的美学意义。该方法使用一系列医用超声换能器进行了演示，并且我们的筛选通过与执业超声换能器设计师和工程师进行的完整析因实验进行了验证。© 2014 ASME
Product form and aesthetics play a major role in consumer preference and product differentiation. During product family design, it is important to differentiate products in the family yet similarities among some stylistic features may connote a more coherent design strategy. Shape grammars offer a method for producing designs with a coherent style along with the ability to control the variation of the output shapes. In this paper, we investigate the use of shape grammars to support product family design, namely, identification of features that shape the perceptions of similarity within a family. A survey-based approach is implemented wherein the impact of a shape parameter on product style is evaluated by comparing design variants to a baseline design. Respondents are asked to rate the style similarities on a Likert-like scale, and candidate shape parameters are screened for aesthetic significance using a fractional factorial experiment. The approach is demonstrated using a family of medical ultrasound transducers, and our screening is validated using a full factorial experiment with practicing ultrasound transducer designers and engineers.© 2014 ASME
