design first steps
Design: First Steps
  • Functional decomposition
design concept
Design: Concept
  • Concept development iterations
  • Two design proposals
    • Redesigned trackless system
    • Modified track system design (system constraints + customer preference)
  • Primary improvement goals:
    • Hand crank, seat position, and foot rest adjustability
    • Reduced impact on body when swinging from side to side
    • Mounting plate that can secure different seat shells
    • Adjustable platform handle locks to lock in place in different Sonar boats
    • Emergency quick-release system
design adjustability
Design: Adjustability
  • Anthropometric analysis to determine amount of adjustability
    • Accommodate about 90% of the population
  • Adjustability:

success and failure
Success and Failure
  • System provides full range of adjustability
    • Foot rest angle (bonus!)
  • System provides greater comfort to user
    • Corbeau seat
    • 5 point harness
  • Quick release tiller
  • System is expensive
  • System should be made more robust
    • Removal of wooden components
    • Foot rests
  • Many parts to manufacture
future work
Future Work
  • Provide adjustability for other popular sailing boats
    • Ideal 18
    • Freedom 20
  • Increase system portability
  • Provide ergonomic handcycling grips (30° tilt)
  • Decrease total installation time
