  2. Description • Coaches and athletes in the Genesee Region of Special Olympics New York are interested in adding bocce to the selection of sports • Many athletes lack the strength and/or mobility to be able to throw or roll the balls used for bocce. • The customer envisions a product that will be adaptable for athletes who have the use of at least one hand and can grip a ball. • Resulting device will make the game of bocce accessible to athletes who normally do not get to participate in the Special Olympics.

  3. Bocce Ball

  4. High Level Customer Needs • Assist in rolling pallina and bocce balls • Maintain skill of game • Low transfer/setup time • High portability • Simple

  5. S.O. Approved Bowling Ramp

  6. Engineering Specifications • Velocity • ≥ 2.77 m/s • Weight • <102 Lbs • Setup Time • < 3 mins • Transfer Time • < 2 mins • Accuracy/Precision • Within one ball distance • Safety • >2.77 m/s

  7. Concept Summary • V-Channel Ramp • Potential energy • Placement on ramp determines distance • Swivel Base • Allows aiming in a 15° bi direction arc • Supports Profile • Damper System • Restricts repeatability • Protective Case

  8. Concept

  9. Concept Side View

  10. Unique Damper Subsystem

  11. System Architecture

  12. High Risk Assessment • Mitigation • Design for highest coefficient and farthest distance • Sensitivity: Analysis done in simulation and physical setup • Old concept: Use V-shaped aluminum w/ same profile • Use simple lock/unlock system Risks • Distance the pallina travels (wet/dry court) • Sensitivity: Ball placement on the ramp • Manufacturing • Composite Material • Critical Item: Unique Damper System

  13. Current State of Design • Design meets all customer needs • Design meets engineering specifications. Full scale testing needed to verify. • On target to come in under $1500 budget with a total build cost of $620. • MSD 1 Schedule: Currently on schedule. • MSD 2 Schedule: Completed for 11 Weeks • Confident in overcoming actual friction on bocce court.

  14. Milestone Schedule for MSDII • Week 2 • Composite Mold Finished • Week 4 • Composite ramp proven • Subsystem completed • Week 6 • Prototype built • Week 8 • Proven System w/ documentation
