  5. Current Design

  6. Design Problem Flaws in the Current Design • Safety Issues • Back Injuries • Ankle/Leg Injuries • Hardware Issues • Poor Interface • Foot Restraints • Comfort Issues • No Adjustability • High Impact • Chafing

  7. Current FitSki in Action

  8. Design Goals • To redesign the current FitSki incorporating four major components: • Enhanced safety for the skier • Reduction of the shock loading on the skier • Improvement of the interfacing of the FitSki with the board surface • Increased seating comfort

  9. Costs

  10. Background • Adaptive water skiing has grown into a popular recreational activity for people with disabilities who experience an increased quality of life when they can be involved in physically active recreational activities. In the Healthy People 2010 report there is a strong emphasis on the need for physical activity for all people because of its close relationship to health and well being. Enhancing the accessibility and safety of outdoor recreation activities, such as water skiing, for people with disabilities will ensure that they have access to all of the health benefits that a physically active lifestyle provides. • Project Website: www.bme.vanderbilt.edu/srdesign/2005/group5

  11. Target Users • Physically Disabled Persons • All who desire the freedom and excitement that able-bodied skiers enjoy but cannot ski using traditional equipment due to a physical impairment • Includes those paralyzed from waist down, chest down, and even neck down • Nashville Users ~ 25-35

  12. Quality Function Diagram

  13. Safety and Performance Foot Restraint • Velcro • Molded flexible rubber Shock Absorbers • Options: • Air, Coil Springs, Oil (dampening) • Concerns • Loading Capabilities • Tune-ability • Durability/Corrosion Resistance Height Of User Above Board • higher position=increased performance + decreased stability • lower position=decreased performance + increased stability Seat Options • Personalized molded seat • Adjustable/universal seat design

  14. Current Work • Website Update • Frame Design Modeled in SolidWorks • 2nd iteration of design mock-up

  15. Future Work • SolidWorks model completion • Research machine shops to have it made or begin construction ourselves for a first working prototype • Website updates • Future testing

  16. Conclusions • Witnessed first-hand the poor interface, shock loading, and the sores from the current seat • A new design is needed • Focus on Wakeboard
