WEBS
Wheelchair Elevator Button System
Background
WEBS is an innovative accessory designed to augment power wheelchairs, specifically catering to individuals affected by Muscular Dystrophy. This technology facilitates enhanced mobility and accessibility for users by extending their reach beyond the confines of their wheelchair's footprint
The device is composed of two main mechanisms. The first one is the deployment mechanism that will release the device out of its tucked position so it doesn’t interfere with the armrest when deployed. Next, is the button pusher mechanism that will perform the task of pushing elevator buttons at different levels.
Technical Details
-
Performed a weighted benefit analysis to initiate the design process.
-
Applied DFMA principles by utilizing bar stock and off the shelf components to design the mechanism
-
Produces 2D engineering drawings using SolidWorks
-
Implemented the wheelchair's movement to simplify the design thus reducing cost and size
This is the first prototype in the product development journey, designed to validate the concept.
Outcomes/lesson learned
-
Successfully designed and built a prototype according to customer requirements and engineering specifications.
-
Developed mockups for testing purposes.
-
Executed basic manufacturing processes (lathe milling, vertical hand press, tapping, laser cutting, etc.) and utilized basic hand tools.
-
Troubleshot and resolved design issues. Below is a table of some encountered problems and potential solutions.
