Team Vision for Problem Definition PhaseGoal:
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.
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 SummaryIndividuals 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.

- Considering the purpose, the team should anticipate potential failure modes associated with construction and use of this document.
- Walk us through a the full experience of using a public bathroom as someone who uses a wheelchair?
- What are your biggest challenges when using public bathrooms?
- For the previous group you worked with on this project, what were some of their pitfalls? What could they have done differently to improve their final prototype?
- Do you have any suggestions for what we should include in our design?
- What is your biggest issue when getting on and off the toilet? Is stability a concern?
- Do you believe it would be beneficial to include some type of device to help with stability while on the toilet?
- Other than just the toilet, are there other aspects of public bathrooms that prove a challenge for you?
- Are the size of the stalls an issue for you?
- Do the grab bars currently include in public bathrooms really help you?
- Are there any hygienic considerations that we should be especially concerned with?
- How would you like to see the seat raise for ease of use?
- Has this been addressed anywhere else that you know of and has been successful?
- What products, if any, have you used before? What did you like/dislike about them?
- What budget is available to us? (Maybe an Art question?)
