  14. Refinement of Project Description

  15. Refined Handle Design Iteration One: Basic shape, destroy rivets to assemble Iteration Three: Eliminates sharp corners, two pieces, design reduces gaps Iteration Two: Two pieces, design reduces gaps

  16. Latch Add-on • Option for users who like the original handles • Only one handle is gripped during connected crutch use • More components needed for assembly than handle design • (Iteration Two pictured)

  17. Testing Results Sliding Button Handle Latch Quick connection time Unsure whether crutches are connected Extended handles for comfort • Quick connection time • More secure connection • Include magnets? • Users prefer this design

  18. Engineering Requirements

  19. Moving Forward

  20. Design for Manufacturability • Rapid Tooling Molds vs. Metal Molds • Breakeven point: 10,000 Units Source: custompart.net

  21. Project Evaluation Successes Shortfalls

  22. What We’ve Learned • Always consider bottlenecks when prototyping • Iterations with a focus on user input are necessary • Communication with the customer is important • Constant check on design drivers • Keep the solution as simple as possible • Compromise between aesthetic appeal and functionality
