An owner-assisted wheel changing device, redesigned with Boothroyd–Dewhurst analysis to cut assembly time and cost by 68%.

A device that helps a car owner lift, position and align a wheel during installation. It went from concept sketches through iterative CAD modelling to a simplified, portable design.

What I did

  • Developed the concept through iterative sketching and CAD modelling.
  • Quantified the redesign with the Boothroyd–Dewhurst method, simplifying the part and fastener structure.

From the bench

  • Exploded assembly used for the DFA analysis

  • Concept sketch: lift and roll

  • Concept sketch: final arrangement
