Universal Play Frame (UPF) An Adapted Sport Mechanism for Athletes in Wheelchairs

What is the UPF? Redesigned and constructed by former ME 428 students Enables athletes with a limited range of motion to play several sports that would otherwise be impossible for them to participate in Hockey, basketball, golf, and soccer attachments

The Equalizer (manufactured by Sportime International)

While the UPF was intended to be an improvement on the Equalizer, there are still many design flaws to be evaluated and reconsidered. The design flaws we in Kinesiology have identified are completely based on use with actual athletes in wheelchairs. But, we need your mechanical engineering expertise for these athletes to fully enjoy this sporting experience.

What are the actual design flaws of the UPF Frame? Lack of frame adjustability Cannot adjust distance or angle of frame from wheelchair to athlete Attachment to chair is time- consuming, awkward, inflexible and unreliable Weight concerns have been addressed. In redesign, weight should not be compromised for frame stability, rigidity, and stiffness

Basketball Attachment UPF frame pulls off ground when athlete pulls on basketball bungee Lift prevents adequate tension/force production Putter attachment rod is in the way of the basketball travel path Rod is not easily removable (requires tools)

Golf Attachment Putter needs to be adjustable in height because wheelchair may require the UPF to be adjusted at different angles. Too much force is required on athlete’s behalf to pull putter Harder for athlete to put ball as far as compared to the Equalizer

Hockey Attachment Thin rectangular handle is difficult for most athletes to grasp Handle is not adjustable Too far away from athlete On right side only Not usable for left- handed athletes Hockey blades run into frame Disables full range of motion of hockey blade

Soccer Attachment Shining Star of the Equalizer Athletes thoroughly enjoy this attachment Main problems surround reaching the scoop, but an adjustment mechanism was made This problem can also be alleviated through having frame attachment to wheelchair be adjustable

The bottom line… Enjoyment derived from the athletes and those who participate with them Play is cathartic Opportunities for play gives them feelings of empowerment in a world that caters to the able bodied. Their time spent with these structures is invaluable However, it cannot be done without engineering marvels like you.
