TANGO
what:
Tango is a redesign of a rollator walker. It focuses on efficient collapsibility and mobility, while looking to address the traditionally neglected aesthetic of the product.
why:
Our main goal was to create a walker for people who want their mobility back. It caters to its audience with low-resistance folding and touch points, and ergonomic grips; we want to take away strain. Walkers are frequently seen as a burden, but they should be seen as an accessory.
who:
This was a partner project, taking place over the course of 7 weeks.
We performed an analysis of the existing rollator walkers on the market.
competitive analysis
THE PAIN POINTS:
We had a user demonstrate common rollator walker talks and describe the pain points.
task analysis
initial sketches
lo-fi prototypes
Simple cardboard models of our favorite
concepts and elements from our inital round of sketches. They focused on the idea of pivoting pieces to reduce the silhouette when collapsing.
1:
Rollators walkers on the market are not compact enough. They don't reduce the walker's footprint nearly enough and they don't collapse efficiently.
2:
Walkers are generally poor on imperfect surfaces. It's difficult to walk and turn.
3:
The tactile elements of walkers are frequently complicated and tricky to use for those with limited physical strength.
4:
Rollators walkers on the market are not compact enough. They don't reduce the walker's footprint nearly enough and they don't collapse efficiently.
mid-fi prototype
After exploration of form in Rhino, we made a model of
PVC, cardboard, and 3-D printed parts.

We advanced our prototypes into more detailed sketches. This allowed us to move forward with a concept where the legs and arms fold around a center axis. We felt it was the most efficient, and simplest to understand folding mechanism.
