Abstract
This portfolio examines the critical tension between functional efficacy and personal autonomy, focusing on how engineering interventions can either support or exploit human well-being. Through two distinct projects, the work addresses the preservation of human agency against physical degradation and predatory digital systems.
Technical Project: The Velvet Maiden
The technical report details the development of a non-invasive electronic knee-distracting orthosis designed to treat knee osteoarthritis by replicating the clinical benefits of surgical joint distraction. The device utilizes a dial-based mechanical system and load cell sensors to apply and monitor distraction forces in real-time. Testing conducted on a cadaveric specimen demonstrated statistically significant lateral distraction of 0.65 ± 0.47 mm at peak forces of 100–150 N. While the prototype did not reach the ultimate 5 mm distraction goal, the results suggest that non-invasive bracing is a potential alternative to invasive procedures.
STS Research: The Workification of Leisure
The STS research paper investigates the "workification" of leisure within Live Service Games (LSGs) and its impact on the identity exploration of emerging adults. It argues that predatory design mechanics, such as battle passes, daily tasks, and pity systems, transition gameplay from skill-based play to uncompensated labor, or "playbour". By transforming the "third place" of digital gaming into a site of administrative maintenance and extrinsic obligation, these systems risk stunting personal growth and eroding the boundary between work and play.
Ultimately, these projects underscore the engineer’s responsibility to restructure biological and digital environments to prioritize human flourishing and user autonomy over mere efficiency or engagement.
