Abstract/Summary

This document includes the problem that is under scrutiny, the background research towards finding a solution, the objectives, scope of the project, the planned overall design process, the preliminary design we have produced and analyzed, the critical design we have manufactured, the testing and results, and the final assessment of the produced design. The problem is lack of easy access and movement for wheelchair users on the beach. Other solutions and designs have been logged under background research. With this information, the scope of work was designed to meet all the needs specified and describe how the specifications will be measured. The overall process was undertaken to produce multiple designs which were then refined into a preliminary design to move forward with. A timeline for the project and analysis of the preliminary design have been specified. The critical design and manufacturing plan for the design are mentioned as well. The critical design is a wheel and lever ratchet mechanism that can be easily attached to any manual quick-release axle wheelchair. The design is a three-part assembly: the ratcheting hub and wheels are the first assembly, the second is the lever which attaches to the first assembly, and the third assembly is the separate front wheel ski mechanism to prevent sinking into the sand.
