两种类型的设计构思过程可以区分在所解决的问题方面:(i)解决方案集中,即生成解决方案来解决指定期望输出的固定问题;和(ii)探索性,即考虑开放式问题的不同解释并生成相关解决方案。现有的系统分析方法侧重于前者,文献缺乏这样的方法,后者。在本文中,我们提供了一种手段,系统地分析探索性思维的第一次通过一种新的方法:分析探索性设计构思(AEDI)。AEDI涉及:(1)开放式思维任务;(2)根据草图对探索的问题和解决方案进行编码;(3)基于编码评估思维能力。我们将AEDI应用于30名专业产品设计工程师的神经成像研究期间完成的19项开放式任务中的812个概念草图。结果表明,该方法提供了:(i)一致的任务,刺激问题的探索;(ii)一个可靠的方法编码探索的问题和解决方案;(iii)一个适当的方式来排名/比较设计师的表现。AEDI使系统分析的好处(例如更大的可比性,可复制性和效率)在探索性思维研究中得以实现,以及更普遍地使用开放式问题的研究。未来的改进包括提高编码的有效性和可靠性。
Two kinds of design ideation process may be distinguished in terms of the problems addressed: (i) solution-focused, i.e. generating solutions to address a fixed problem specifying a desired output; and (ii) exploratory, i.e. considering different interpretations of an open-ended problem and generating associated solutions. Existing systematic analysis approaches focus on the former; the literature is lacking such an approach for the latter. In this paper, we provide a means to systematically analyse exploratory ideation for the first time through a new approach: Analysis of Exploratory Design Ideation (AEDI). AEDI involves: (1) open-ended ideation tasks; (2) coding of explored problems and solutions from sketches; and (3) evaluating ideation performance based on coding. We applied AEDI to 812 concept sketches from 19 open-ended tasks completed during a neuroimaging study of 30 professional product design engineers. Results demonstrate that the approach provides: (i) consistent tasks that stimulate problem exploration; (ii) a reliable means of coding explored problems and solutions; and (iii) an appropriate way to rank/compare designers’ performance. AEDI enables the benefits of systematic analysis (e.g. greater comparability, replicability, and efficiency) to be realised in exploratory ideation research, and studies using open-ended problems more generally. Future improvements include increasing coding validity and reliability.
