Tetra Ryerson

Engineering that breaks down barriers

Tetra Ryerson is a student run group that works with the North American Society of Tetra. Together we create assistive devices for individuals with disabilities

Home Lift Accessibility

Individuals, primarily adults, with hip fractures or those that have undergone hip replacement surgery and have limited mobility as a result, find it difficult to get into and out of their homes through interior garage door entrances. They either have to sit down on the top staircase level and rotate/spin themselves into their house, or use other inefficient methods that can potentially pose risks to patient health.

A potential solution is to install ramps or stair glides, however the effectiveness of this solution is also reduced when facing narrow entrances.

Tetra members will be challenged to design and develop a universal/flexible device, similar to vertical porch lifts, that is portable, light weight, yet large and strong enough for the average adult to stand on. The design should also explore and address fall prevention. Members will be guided by Amarpreet Gugjral, a licensed Ocupational Therapist working at St. Elizabeth’s Hospital.

Population Description: Adults with hip fractures or hip replacement surgery with limited mobility.
