The objective of this research project is to produce the knowledge needed to evaluate the effectiveness of engineering design idea generation methods and to distinguish between their necessary and superfluous components. This research will combine the highly controlled lab experiments and atomic process models from cognitive science with design experiments from design research. Instead of conducting experiments by using an idea generation method in its entirety, each method will be decomposed into its key "ideation" components and its overall effectiveness predicted by testing the effectiveness of its components and their mutual interactions. Lab experiments will be directed at studying key ideation components individually, while the design experiments will examine interaction between components and their relation to outcome by mutating their constituent components. Explanations for why and how ideation components are effective will be researched from accepted models of atomic processes and structures already available in cognitive science. Effectiveness will be evaluated in terms of four measures: fluency, quality, variety, and novelty of design concepts generated. The results of the study will be consolidated into a model of design ideation by combining and modifying several elements from existing models. The proposed ideation model will be validated through final experiments in industry settings.Two important results should emerge from this research: (1) data from the empirical studies that can be interpreted in terms of both theory and applied practices, and (2) a system for pursuing additional research questions about ideational aspects of conceptual design theory. An understanding of the relationship of ideation processes to design outcome will help companies determine which method to use under given conditions and how to constitute design teams. This work will also help educators in finding better ways of teaching design synthesis.

该研究项目的目标是产生评估工程设计理念生成方法的有效性所需的知识，并区分其必要和多余的组成部分。这项研究将把高度受控的实验室实验和认知科学的原子过程模型与设计研究的设计实验结合起来。不是通过整体使用想法生成方法来进行实验，而是将每种方法分解为其关键的“想法”组件，并通过测试其组件的有效性及其相互交互来预测其整体有效性。实验室实验将针对单独研究关键的构思组件，而设计实验将通过改变其组成组件来检查组件之间的相互作用及其与结果的关系。将根据认知科学中已有的原子过程和结构的公认模型来研究构思成分为何以及如何有效的解释。有效性将从四个方面进行评估：所产生的设计概念的流畅性、质量、多样性和新颖性。通过组合和修改现有模型中的多个元素，研究结果将被整合到设计理念模型中。所提出的构思模型将通过行业环境中的最终实验进行验证。这项研究应该得出两个重要结果：（1）来自实证研究的数据，可以从理论和应用实践方面进行解释，以及（2）一个系统用于追求有关概念设计理论的构思方面的其他研究问题。 了解构思过程与设计结果之间的关系将有助于公司确定在给定条件下使用哪种方法以及如何组建设计团队。这项工作还将帮助教育工作者找到更好的设计综合教学方法。
