3. DESIGN TASK

4. The Mission Statement of our TEam is:
To design, build, test, and sell a device that allows teenagers/young adults to safely walk on the surface of pool water for a cost lower than $100.

8. Table 1. Customer Needs to Specs
What the customer wants
SPECS
88.5% of people want a device that will cost more than $20
The device will be more than $20 so it does not feel cheap, but it will cost less than $45
54% of people want a device that lasts 1-3 years
Made out of materials that are durable, but inexpensive
4 out of 33 people say that they want to "be like Jesus"
Standing straight up on the surface of water and still having the ability to walk like they are on land
Many say able to walk on water/stay afloat
Enough surface area/buoyancy to keep a person under 210 lbs afloat (25 Gal)
Function over looks "cool"
Money should not be spent on looks if the function is not yet up to par
12 out of 35 people say the device should be blue
Blue will make the device appealing to 12/35 people
48.7% of people say the device should fit in a backpack
The device should be smaller than 2ft by 1ft if possible. Width should be less than 8 inches. Device should be lightweight
37.14% of peope say the device should be in between fitting in trunk/backpack
If the device is bigger than the above specifications, then it is still OK

14. The walker design was chosen over all other brainstorming Ideas Because it fits our Specifications the best.
Inexpensive
Safety
Portability
Durability
Aesthetics.

15. ENGINEERING ANALYSIS

16. Our calculations were flawed before the first test, but correct before the second.

17. The Subsystems of our design can be broken down into three categories.

Figure 4. Buoyancy
Figure 5. Accessibility

18. A bill of materials allows for a cost comparison between the teams.
