1. E-Design 100 PROJECT TEAM 7

2. GROUP MEMBERS Group Leader : Ryan Baer Resources : Nicholas Tiches and Alex McCoy Customer needs: Kashan Nazim

3. PROBLEM STATEMENT This is an opportunity to create and sell a product that allows college students to walk on and transport weight across a body of water.

4. For our stake holders, our products needs to be cheap, durable, environmentally friendly and allow someone to cross water. STAKEHOLDERS: Natatorium safety officials Consumer product safety commission Department of Environmental Protection Dr. Colledge College students People that fish and own boats Team 7

5. According to the Natatorium officials, it cannot touch the sides or bottom of the pool, can’t be flammable, and no material must be left in the pool

6. General SPECIFICATIONS Must be durable Must support a 300 lb person + its own weight Must allow college student to walk on water Must have a density less than water i.e must float Must be light enough to carry

7. DETAILED SPECIFICATIONS Volume displaced: Must allow displacement of 5.77 ft^3 Must be under 30 lbs Must be intact after two tests

8. Possible ideas 1.Water shoes 2.Bridge 3.Inflatable ball 4.Stilts 5.Raft + Oars 6.Inflatable tubes

9. The water shoes were selected for our best solution.

14. PROJECT DESIGN Each shoe must be close to dispelling the volume for walking motion (Width = 1.5 ft, Length= 5.5 ft, Height= 5ft) ==  Dimensions are PER SHOE Density of the foam : 1.3 lb/ft^3 Bouyancy: Volume_disp=(Mass_Person+Materials+Added Weight)/(Density_Water) =(50lb/62.4lb/ft^3)= 5.77ft^3=Volume_disp Mass_foam+Mass_weight=Mass_water Depth 1.3(lb/ft^3)*L*5.5ft*1.5ft+350=62.4lb/ft^3(L-L1)(5.5ft)*(1.5ft) L1=.43 ft=depth Center of Mass Xcm=-.127 ft

15. Our final design cost $115, the most expensive part was the XPS foam. Duct tape and screws were also used. From our survey, we approximate we could sell this idea for 250- 300 dollars.
