WIP: Effects of a prototyping course on capstone design performance

Presented at Biomedical Engineering Division (BED) Poster Session

At the University of Illinois Chicago (UIC), our design spine includes a 300-level prototyping class to augment practical engineering skills. The prototyping class, entitled Physical Prototyping for Design, aims to increase familiarity and confidence working with various materials, power tools, and machining techniques. We hypothesized that participation in this course would enhance student ability in capstone design. Specifically, during the first semester of capstone design, students individually propose a technical solution for their team project based on design inputs. This affords us the opportunity to evaluate the efficacy and translational outcomes from the prototyping course on engineering skill and ability in capstone design. From 2022-2024, a total of 20 students completed the prototyping course. Seventeen of these students remained in BME and were enrolled in capstone design between 2022-2024, where they were placed among ten different teams. The design proposals from students who completed the prototyping course were scored against their team members who did not take the course. Scoring was performed based on written communication, graphical communication, and materials identification. Projects ranged from machine learning application (all software) to rehabilitation treadmill (electromechanical systems) and imaging phantoms (all hardware and CAD). On average, students from the prototyping course earned 70±13% of the available points from design proposals whereas their peers scored 68±11% (N=10 teams, p=0.72). Though, for projects that utilized most of the skills fostered in the prototyping course (e.g., the imaging phantom used CAD, 3D printing, and physical design features exclusively), the students that took the prototyping course scored substantially better than their peers. Overall, we report no significant effect of early prototyping exposure to design proposal ability in capstone. Future versions of the prototyping course will be revised to introduce and reinforce additional skillsets that may readily translate to capstone design.
