工程创意生成是新产品开发的关键部分，物理模型是此设计阶段使用的工具之一。不幸的是，关于有效使用物理模型来支持创意生成的指导方针很少。需要澄清物理模型的优点和缺点，以便工程师知道何时何地有效地实施它们。先前的文献表明，物理原型的设计固定是有潜力的。这限制了所考虑的解决方案。相比之下，其他建议鼓励广泛使用物理模型，而心理学文献表明，物理表征有可能通过支持设计师对物理现象的心理模型来实现更可行的设计。本研究通过具有四种条件的受试者间实验来评估这些问题：仅绘制草图、构建、构建和测试以及约束草图。没有观察到设计固定的证据。结果表明，物理模型补充了设计师的心理模型，从而产生更高质量的创意（功能创意的一部分）。这一结果显示了通过战略性地实施快速且廉价的原型设计方法来提高设计师创新能力的潜在方法。版权所有 © 2010 ASME
Engineering idea generation is a critical part of new product development and physical models are one tool used in this phase of design. Unfortunately, few guidelines about the effective use of physical models to support idea generation exist. The advantages and disadvantages of physical models need to be clarified so that engineers know when and where to implement them effectively. Previous literature indicates there is potential for design fixation on physical prototypes. This limits the solutions considered. In contrast, other recommendations encourage the extensive use of physical models and the psychological literature indicates that physical representations have the potential to lead to more feasible design by supporting designers’ mental models of physical phenomena. This study evaluates these questions with a between-subjects experiment with four conditions, sketching only, building, building & testing, and constrained sketching. No evidence for design fixation is observed. The results show that physical models supplement designers’ mental models, thereby leading to higher quality ideas (fraction of functional ideas). This result shows a potential way of improving designer’s innovation by strategically implementing fast and cheap prototyping methods.Copyright © 2010 by ASME
