Case studies of problem exploration processes in engineering design

Abstract

Looking beyond the presented problem can allow new perspectives to emerge, opening up the possibility of more varied solutions. Little research exists about how engineering designers engage in this process, which we call problem exploration. In a study with engineering students, each student talked aloud as they worked to create design solutions; next, we asked them to explain their problem focus and to define the problem they addressed in each solution. The protocols revealed multiple cognitive strategies used to structure and frame the presented problem in alternative ways. Further research is aimed at empirically-based design tools to support problem exploration in engineering design.
