P hantom A daptive S occer T raining A ttachment EF 152, Spring 2019 D218 - 4 Andrea Wilkerson. Daniel Dos Santos. Julian Ruibal. Ben Tran.
Less Flexibility/ Not as Effective Not Detachable • more focus towards other sports • encourages participation • explore and develop skills • physical development • schools and youth soccer teams • The American Youth Soccer Organization (AYSO). Made for Young Athletes Benefits: Save athletes time and money Makes the sport more intuitive as a whole More flexibility Encourages user training More opportunities
In the Making Originally Proposed Design: • incorporating a proposed layer to accommodate the port • 3D printed screw and port • Tether molded into screw Brainstorming Process: • Modifying air hole • Problem: Air hole is too small for tether to be attached durably After cutting into soccer ball: • Port embedded into the rubber layer • Design idea inspired by air hole
Final Design • TinkerCAD software • Enclosed Printer • 3D printed (PETG filament)
Feedback and Review • Interview with Mark Wilkerson • A former AYSO coach • What the design would need to accomplish? • “Training (Juggling) efficiently w/out compromising the user experience” • What does the design need to do in order to differ from existing products? • “... less restrictive and more versatile for both training and scrimmages” • Does our final design prototype meet originally proposed needs? • “very durable, user friendly, removable and cohesive design”
Retail Cost /unit Average retail price of a PU leather size 4 soccer ball = $15 • community service design • not seeking additional profit • additional materials costs $0.70 per ball • average market price of $15 per unit Design Time • 4 people x 12 hours = 48 hours(cohesively working together as a team not including individual work time which is noted on team log) Cost and Time Estimates Prototype Costs: 5 mm 750 Paracord $10.00 Plastic Screw and Port $0.11 Size 4 Soccer ball $10.00 Epoxy or Gorilla Glue $5.00 Total $25.11 Material Cost for Production of 1,000 Units 750 Paracord: $0.15/ft (if you buy 200 ft in bulk) PETG Plastic Filament: $0.035 /gram ($35/kg in bulk) Soccer ball: $2 /unit Cost of 1,000 units=($2 + 4ft Paracord($0.15)+3 g filament($0.035))*1,000 Cost of 1,000 units = $2,705 Cost to Manufacture Single Unit= $2.75 Our product is a community service design project so we are not including any additional profit compared to a standard soccer ball on the market .
Conclusion • helping the community of young athletes • makes soccer more intuitive, encouraging and exciting to learn/ improve • cost effective • applied to all originally manufactured soccer balls • reach a wider audience • potential to revolutionize the soccer community and sport as a whole
