Project Summary

How might we ensure that users with physical challenges will be able to independently incorporate themselves into physical activities without feeling an active limitation?

Design, prototype, test, and spec a device that attaches to at least 75% of wheelchairs, walkers, and standers, which will provide its users with the ability to strike, throw, and catch; actions that they would otherwise be unable to perform on their own.

The OvercomerTM is a form of assistive technology that allows the physically challenged to engage in physical and social activities from their stander, walker, or wheelchair. It should allow the users to interact, socialize, and enjoy activities that they would typically be unable to participate in. Currently there are no universal assistive technologies available that allow physically challenged individuals to participate in recreational activities. A prototype has been developed for lower extremity functions which has a base attachment as well as a hockey stick, catching net, soccer ball guide, and bowling attachment. The prototype attachments have limited functions and are not in a manufacturable state. Currently, there is no prototype for any upper extremity attachments.

The goal of this project is to design and develop the upper extremity portion of The Overcomer which allows its user to participate in a variety of physical activities ranging from gym class activities to physical therapy exercises. The Overcomer must be affordable, durable, easy to transport, user friendly, and compatible with most mobility aids. The end result is a highly functional prototype to be manufactured and marketed.

The Overcomer must not impinge on any other patents and it must meet all standards and regulations for attachment to Class I medical devices. The product should not interfere with the functions of mobility aids and should cost between $500 and $1200 for purchase.

Customer Requirements


Decompose the Problem Statement into functions of elements needed to satisfy the customer.

Customer Requirement List

  1. Between $500 - $1200 to purchase
  2. Aesthetically pleasing to user so they feel confident and comfortable using it
  3. Easy to attach so anyone is able to do it (including aids, users, teachers, whoever)
  4. Easy to attach for quick assembly
  5. Adjustable to include all user types (Can be adjusted to different heights or positions)
  6. Versatile to allow users to participate in more activities (Can be used for many activities/sports)
  7. Compatible with at least 75% of all mobility aids
  8. Easy to use for both physically challenged user and aid so it can be integrated into a daily routine
  9. Product must be durable so it can withstand the normal demands and uncertainties of the environment it’s in
  10. Compact and lightweight so that product is easy to transport and store
  11. Provides significant independence and improvement to quality of life for the user
  12. Product must be lightweight so it can be easily moved by user or aid
  13. Product must be safe for user, aids, and surrounding individuals to prevent user/aid injury or death
  14. Product should not be extended too far away from user because it gets in the way of other participants
  15. Must address the four main movements required of the upper body in any typical recreational activity: throwing, catching, shooting, striking
  16. Focus primarily on mobile physical challenges vs emotional or cognitive
  17. The Overcomer and clamping system will not damage mobility aids or surfaces in environment.
  18. The Overcomer must be able to interface with attachments developed and modified in the future.
