Design Task Mission Statement - It was our mission to grab the opportunity to make money by building a device that would allow the user to “walk” on water. Stakeholders, functionality - Any customer that wishes to walk on water and ANGEL investors are our stakeholder. Our product is designed to function as shoes to walk across the water. Needs assessment - Define the Scope: To make money off our design, Gather Raw Data, Interviews, Focus Groups, Observation, Interpret Raw Data, Needs statement, Organize Needs, Hierarchy, Establish Importance, Surveys, Quantify needs, Reflect on the Process, Continuous Improvement Design specifications - 1. Walking- bipedal motion; legs move independently 2. The device must be portable 3. Meant for people ranged from a certain age group 4. The device should be able to handle different people of different sizes and weights 5. Should be stable 6. Should be able to be used over many years 7. Easy to dispose of should it break 8. The person using the device should be moving in a motion similar to walking

Design Idea and Selection Table 1. Design Matrix

Calculations and Considerations How deep will it sink 300 lbs 5.75 in 200 lbs 3.84 in 100 lbs 1.92 in Will it float Max Load 300 lbs 696.5 in > 681.95 in Total Load Absolute max load 306.5 lbs How high will it rise At rest 5.87 in Table 2. Calculations Fig 7. Calculations 1 Fig 8. Calculations 2

System and Subsystem Description System - Twin Ski like system The Subsystem - Flap design ➢ ➢ User shuffles rather than steps Underneath skis to displace water ○ ○ ○ Allows flap subsystem to work ○ Allows user to glide forward on water Fig 11.
