CHALLENGE: Design a fully engineered CAD

CHALLENGE: Design a fully engineered CAD model and manufacturable prototype for a portable power-assist device that inserts into the 1.5” inner diameter winch shaft on standard flatbed trailer winches and automatically tightens/releases cargo straps. SOLUTION: Expandable Steel 3-leg collet. Output rpm between 30–50 RPM under load. Output torque target: ≥ 50 N.m. OUTCOME: Prototype-Ready for 3D Printing, delivering manufacturing files compatible with manufacturer providers like Protolabs, Jiga, PCB Way, or Xometry. Case design with injection molding techniques.
