Team Vision for Problem Definition Phase


The purpose of this phase is for the team to gather information pertaining to the scope of the project, customer requirements, design parameters, and resources available for the task. In order to move forward, a clear path to a well defined end goal is required. This information will be gathered from research and subject interviews.

Actual Progress:

During this phase, a clearly defined problem statement was drafted from customer interviews and interviews from people within the disabled community. Customer and Engineering requirements were drafted that do not conflict with one another or the ADA standards, although they may be subject to change when project capabilities are realized.

Project Summary

Individuals who are deemed disabled can have trouble with some everyday tasks, such as using the restroom. To provide disabled peoples a better experience while in the restroom, the Americans with Disabilities Act (ADA) has established federal regulations for what constitutes an accessible restroom facility. These regulations outline the minimum dimensions to be allotted as well as positioning of grab bars for ease of transfer to and from the toilet. Due to the nature of some disabilities, some individuals do not find these accommodations adequate and require a significant amount of time or help from an aide or healthcare professional to complete the task of going to the bathroom.

A new system can be introduced so that any wheelchair bound individual can use the restroom in a safe, quick, and easy fashion. The key steps to be addressed by this device are the processes of transferring to the toilet, cleaning themselves, and transferring back to the chair.

The outcome of this venture is a fully operational prototype. This prototype will be demonstrated to the customer and at ImagineRIT. It is desired that the design be able to be incorporated in an existing accessible restroom without being cost prohibitive or extensive modification to the facility.
