Abstract

Drivers with limited hand dexterity often struggle to operate traditional windshield wiper stalks, leading to delayed activation and reduced visibility. This project developed a simple, low-cost retrofit interface that improves accessibility without modifying the vehicle. Using stakeholder input, OEM stalk measurements, and iterative prototyping, our team defined key specifications and refined a 3D-printed clamp-and-lever design. Verification testing showed a maximum actuation force of ~3 N, axial retention above 45 N, and an installation time under two minutes. The final design meets all high-priority requirements and offers a practical path toward improving driving safety for users with dexterity limitations.
