The Assistive Leg Implement for Gait Training (ALIGATR)
Design Project
Mar. 2021 - Jun. 2021
For the Shirley Ryan AbilityLab in Chicago, I collaborated with three other Northwestern engineers in developing a medical device designed to prevent patients from crossing their legs when walking.
After evaluating various mock-up concepts with user testing and an alternative matrix, we found our most successful design to be a comfortable, minimally invasive, and easy to clean solution (shown in the image on the right). In terms of creating the mock-up, I was responsible for selecting materials and manufacturing.

Mock-up Design Concept
Once satisfied with our simple and suitable concept, we designed our prototype. I took on the material selection, manufacturing, and assembly. For instance, I selected foam that could adhere and be easily maintained. The bands were chosen to be comfortable and secure properly onto the user’s legs.
