Problem

We embarked on designing for the human body with a focus on the ecosystem of the hand, targeting an injury-prevention device for athletes. The challenge was to address real-world constraints: comfort during long training sessions, compatibility with various grip styles, and the need to translate ergonomic principles into a practical wearable that does not hinder performance. We began by mapping common injury vectors in sports where grip and hand motion are critical, and we identified gaps in existing devices that didn’t sufficiently consider dynamic hand postures.

We observed that athletes often tolerate imperfect protection because comfort and usability trump marginal gains in protective features. This tension between protection and unobtrusiveness created a core problem: how to design a device that feels nearly invisible in action while providing meaningful injury prevention. We aligned our goals around a system that could adapt to different hand sizes, grips, and activity intensities without compromising feedback or control. This required an integrated approach across form, materials, and user experience.

Solution

We modeled and prototyped CAD components in Autodesk Fusion 360, prioritizing ergonomic contours, breathable materials, and modular attachment points for quick customization. Our iterative design process incorporated athlete feedback to refine grip alignment, strap tension, and modular sensors that monitor impact and range of motion. The result was a CAD-driven platform that could be tuned for different sports while maintaining a lightweight, low-profile profile that minimizes interference with finger dexterity.

We validated feasibility through rapid prototyping and user testing, translating insights into a scalable manufacturing plan with emphasis on comfort, durability, and instructive feedback. The final concept integrated a hand-centric fit, data-ready sensors, and a feedback loop that could inform athletes and coaches about posture, loading, and potential overuse risks. This approach balanced protection with performance, enabling athletes to train with confidence.
