P14006: Bathtub Lift


Project Summary Project Information

A bathtub lift is a device that provides assistance to an individual with physical disabilities, including limited balance, coordination, or mobility. The device can greatly reduce movement difficulties by raising and/or lowering an individual into the tub by utilizing a seat (powered by a hydro pump) paired with a simple control module. Additionally, the lift can be used to facilitate tub entry and exit. As a result of accelerating population growth, the number of aged individuals will greatly increase over the coming decades. Among other needs, the demand for water powered assist devices will grow in demand due to the device's compatibility with most existing structures, ease of use, and overall reliability.

This project focuses on improving the design of a previously developed bathtub lift. Theresa Loce is a wheel chair user who relies on this type of device daily. However, the model she is currently using does not meet her needs. The goal of this project is develop a water powered bathtub lift that is, among other requirements, sturdy, comfortable, easy to use and clean, makes minimal noise, and takes into account any physical limitations the user may have. The expected end result is an installed bath lift for daily use that allows Theresa to maintain autonomy and privacy.

We would like to thank Linak for providing a customized electric linear actuator at a discounted price. In addition, we would like to thank the academic staff that supported this project with the stress analysis on the scissor legs and providing information about Linak to use as a supplier. Furthermore, we would like to thank the Brinkman Lab in the Kate Gleason College of Engineering for the manufacturing of this product. Finally, all expenses were covered by Rochester Institute of Technology.
