    • Redesign team P12031's Motion Assistive Seating Device for Sailing (Keith Burhans)

Gold Medal Sailing Seat

Motion Assistive Seating Device


Specifications
Specifications

  • Primary customer needs:

    • Provide adjustability for multiple users

    • Provide adjustability for other Sonar boats

    • Increase safety

    • Increase mechanical advantage

    • Provide enough space for Jib Transfer Bench (P13031)

  • Translated into engineering specifications

1 = most important


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
