Abstract
The goal of this research focuses on the design for manufacturing assembly (DFMA) heuristics and observes how the application of different modalities affect the participants’ abilities to redesign for manufacturing assembly. By using this methodology, a study was carried out to investigate how novice students apply heuristics to redesign for manufacturing assembly when heuristics are provided in different modalities.
All participants were given a packet with three design problems corresponding to the three heuristics tested: (1) reducing the number of parts, (2) minimizing fasteners, and (3) designing parts that are easier to assemble. With each heuristic they received an example in a different modality, either in text, visual, or tactile form. The novelty and quality of each redesign was evaluated and compared between modalities. The hypothesis was that participants would face more challenges in understanding and utilizing the text only heuristics, resulting in a lower quality of redesigned solutions compared to the other two conditions. Another hypothesis was that participants would become fixated on the tactile aides, resulting in lower novelty of their redesigned solutions compared to the other two conditions. Results showed promise in the modality presented affecting the quality of a redesign for two of the heuristics presented. All other novelty and quality scores did not provide conclusive evidence regarding the effectiveness of the intervention and the varying modality in assisting the participants. This study contributes to guiding designers DFMA during part design, focusing on the effects of modality presentation on redesign tasks and highlighting its potential benefits for novice designers in an engineering education context.
