Abstract
Prototyping is central to the engineering design process. Physical prototypes facilitate learning about a design concept’s functionality, feasibility, etc. at various stages of the engineering design process. The relationships between prototyping strategy and modeling behaviors are not well understood. Through a student design competition, the effects of parallel and iterative prototyping strategies on computer-aided design (CAD) behaviors were investigated and compared. To investigate the effects, the feature trees in students’ CAD assemblies were recorded and compared using a range of statistical analysis techniques. Results show that designs with less complexity (as captured through the feature trees) were more likely to have a positive performance in the design competition. In addition, results suggest that the two different prototyping strategies had an impact on participant usage of CAD package functionality. These results showcase what functions students in an introductory engineering graphics course are most likely to use to model their design concepts. Overall, this work contributes to a growing body of knowledge on how an iterative or parallel prototyping strategy impacts the engineering design process.
