Concept and Rationale:
Based on our user testing and mockup creation process, our team has evaluated the yoga belt mockup to become our design freeze. This design was the most convenient for the user during the user testing phase as our user mentioned, “This strap is easy to grip on and helped me get my leg over the bed faster.”
The eLEGvate is made up of 3 distinct components: Yoga Belt, Handles, Strip of Rubber.
The yoga belt is the primary components that acts the rope which a user pulls their leg up without having to use their lower body as much. It is inelastic so it does not stretch when being pulled and is stiff enough to not break under heavy stress.
The handles are used for a user to grab and have a better grip of the device when using. The handles are made up of plastic which was request made by the primary user because he is able to hold plastic handles better than rubber. The handles also have a finger wells to provide for a more ergonomic feel when using the eLEGvate. They are positioned in two spots on the yoga belt, one towards the top and one towards the bottom. The top handle is used for larger movements with the legs because it provides a large torque for the user to move their legs, while the bottom handle is used for smaller and more precise movements.
The rubber strip is used to provide a friction surface so a user can place their feet on yoga belt without it slipping off. The rubber strip allows for bare feet, socks, and shoes to worn while using the device with minimal risk of slipping out of the device.
To deploy the Yoga Belt, the user should do the following:
Grasp the Yoga Belt by the two top handgrips.
Secure the feet at the bottom end of the belt.
Adjust the two handles to his right arm.
Start pulling his leg with his right arm
Once his leg reaches the chair on the side and the bed rail, Marc can switch and move to a lower handgrips as he wishes
Continue lifting the leg beyond the bed rail until it reaches the pillow
Shake the Yoga Belt off his leg to take it off
As shown in the image above, the different handle straps attached to the belt that will allow Marc to grab onto at different lengths. As we observed during user testing, it was easier for Marc to grab onto the higher handlers at the top of the belt in the initial pulling phase, then he gradually reaches down to the lower handles half way through the belt as he continues to lift his leg from the floor to the bed.
Benefits to our design:
Allows the user to easily lift his leg to the bed
Provides a secure handgrip to pull his leg off the floor
Tailored to the user’s length and weight
Allows the user to watch TV in a comfortable position instead of falling of the bed
