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

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.

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.
