Problem Statement Some sort of lift or easier way for a person with a disability who kayaks to get out of the kayak.

Problem Definition People who have been paralyzed from the waist down, still like to participate in recreational activities like kayaking. However, there is a great deal of difficulty getting in and out of the kayak.

Existing Products Hoyer Lifts Specialized docks Benches

Negatives to Existing Products Expensive Not as portable Not built to last Can't get directly into the water

Concept #1 This concept is a bench with adjustable legs, and a rotating top that can swing out over the kayak so that the person can slide right into the kayak. We did not choose this design because the bench would be very unstable once the top was swung out over the kayak.

Concept #2 In this concept we used the idea of a floating bar and designed it to have multiple bars like a ladder. This would allow for the person the climb the ladder and lift themselves out of the kayak. We did not choose this design because it would be unstable because it was on the water, and also because we didn't think about how we were going to get the person from their wheelchair to the platform on the water.

Concept #3 is a floating platform with a crane on it. This concept is meant to lift the person in and out of the kayak from the platform that is floating on the water. We did not choose to use this concept because we didn't think about how we were going to get the person from their wheelchair to the platform on the water. Also this design is not very portable.

Concept #4 This concept is a bar that sits half in the water and half on land. It incorporates the bench in it as well. This bench slides out from the land to where the kayak is. We did not choose this design because it would be unstable and also not very portable.

Final Design Our final design selection is a hoist designed to be used in a truck hitch. Due to the fact that the person has no use of their legs this was the best choice out of all our designs. This design is as portable as a kayak and can be used anywhere a vehicle can access.

Selection Of Concept

Manufacturing and Testing As for making the kayak crane. Most of the project was assembled off campus. While final assembly and testing was done on campus. After the first test we had to replace the lower rod that goes through the bearings.

Conclusion In conclusion our crane held up but could be improved. More structural support would be beneficial. Also the winch is hard to use and would benefit from an electrical winch. If we were to make this again these improvements would be more expensive and add additional weight. But the design would be highly improved.
