Concept Screening

Concept Scoring

Subsystem/System Propulsion was the subsystem of designing of our propulsion strategies. We used 5 folders to catch the water and propel the shoes forward.

Subsystem/System Buoyancy is the subsystem defined as the ability for the shoes to float and support the weight of the rider.

Subsystem/System Stability was the subsystem that we looked how to make the shoes as stable as possible in water. Dimensions of the final product 0.305m by 0.318m by 0.914m

Subsystem/System Structure was the subsystem involving the design of the physical structure of the shoes to make sure it was strong enough to withstand the forces acting on it.

Subsystem/System Materials was a subsystem involving the selection and gathering of materials for the shoes.

Cost Analysis

Prototype 1 Flaws Low speed Water entering through the top Shoes drifting apart Prone to tipping forward and backward in the water

Reevaluation In Summary there were some changes that we would do in order to improve the functionality of our Water Runner. Those adjustments would include: Increase Length Replace ropes with fins Add side supports
