Figure SEQ Figure \* ARABIC 1: One of Joe Kabe’s students using the OvercomerTM

Project Information * Overview:

Approximately a fifth of the United States population deals with some sort physical disability or limitation. Those with a physical disability are twice as likely to be physically inactive during the week as those without a disability. Students with a disability in particular are less likely to participate in activities, regardless of whether they are physically able to, resulting in decreased socialization and leadership development.

The most common way of helping the disabled cope with their limitations is through assistive technology. Assistive technologies are those technologies that are used to increase, maintain, or improve a disabled individual’s functional capabilities. Currently there are no universal assistive technologies available on the market that allow physically challenged individuals to participate in recreational activities.

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. The idea was initially developed and later patented by physical education instructor, Joe Kabes, for use with his students (figure 1). By partnering with RIT’s MSD program, Kabes hopes to turn his ideas into commercially marketable products. Ideally OvercomerTM devices should allow their users to interact, socialize, and enjoy activities in which they would typically be unable to participate. Previous MSD teams have developed prototypes of the OvercomerTM that have received positive reviews from those that use and those that are affected by them. MSD teams P17047 developed a version of the OvercomerTM for upper extremity activities such as catching, throwing and striking, and MSD teams P17046 and P18046 developed a lower extremity device for use in soccer, hockey and golf. Current Project Objectives:

This project continues the work completed by team P18046 last year on assistive devices for capture, transport and shooting a soccer ball. The team developed initial prototypes that must now be refined to make the devices: (1) more effective at converting energy input by the user into motion, (2) more adjustable for various user capabilities, (3) more manufacturable and (4) more of a marketable product.

The mechanism used to catch a soccer ball worked reasonably well but the shooting mechanism was generally unreliable and weak. The attachment mechanism worked very well in adapting to

a wide range of wheelchairs. However the attachment components were too expensive for the target market. The customer very much liked the fact that the whole assembly could be pivoted over the child’s head to allow quick egress.

Generally, The OvercomerTM must be affordable, durable, easy to transport, user friendly, and compatible with most mobility aids. The Overcomer system of devices should be able to be easily and quickly secured to the wheelchair, walker or stander, etc. without interfering with its function. Finally, the OvercomerTM must not infringe on any other patents and it must meet all standards and regulations for attachment to Class I medical devices.

Common Mobility Aids http://www.rifton.com/products

http://www.r82.com/products/

The products that these companies sell are a large majority of the market. Designing the Overcomer to attach and work with a multitude of these various products is an important goal. The Overcomer should attach and function safely with most manual and power wheelchairs, gait trainers/walkers, and standers on the market. The device will need to be able to attach vertically or horizontally, secure to a variety of tube diameters and shapes, not interfere with the proper functioning of the ambulation device.

Special Olympics and Disability Sports Organizations:

The Special Olympics and other adaptive sport organizations listed below are markets that I would like to see the Overcomer be utilized in. There are many of the games and activities that I can see the Overcomer revolutionizing and changing the way in which individuals play and enjoy these sports and activities.

Preliminary Customer Requirements (CR): Use these as a starting point for generating interview questions and developing/refining the actual CR for your project.

Attachment:

● Attach to multiple types of mobility aids including standard and powered chairs, standers and walkers

● Easy to adjust to fit various chairs and users ● Attach quickly and easily ● Protects the equipment to which it attaches ● Allow quick egress

Playing Catch:

● Assist user to shoot a soccer ball 5-30’ ● Assist user to catch a soccer ball kicked 5-30’ ● Allow two users with mobility aids to pass a soccer ball back and forth ● Adjust to the abilities of each child (full assistance to partial assistance) for aim angle and

force applied ● Stretch goal: Shoot and catch multiple kinds of balls ● Provide greater energy to the ball than last year’s prototype

User experience:

● Allow normal movement with mobility aid ● Minimize turning radius ● Reduce the stigma of disabilities ● Allow user to better participate in group sports ● Look like it would be fun to use ● Adjustable challenge level ● Aesthetically pleasing ● Marketable to users and caregivers ● Durable ● Transportable ● Lightweight

Manufacturing:

● Simple mechanisms ● Reduce costs ● Reduce weight ● Reduce labor for manufacture and assembly ● Design for manufacturability ● Design for assembly

Note: Team should focus on how much energy to deliver to the objects and how they will do it efficiently. * Preliminary Engineering Requirements (ER):

● Percent of common mobility aids accommodated: 75% ● Damage to mobility aid from attachment: No!

● Time to attach: 30-60 s ● Final unit manufacturing cost of $200 - $400 ● Weight of attachment device: 2-5lbs ● Weight of Overcomer modules: 10-20 lbs ● Additional torque required for mobility aid use: 2.2 ft lb ● Accommodates users of heights: 3-5 ft ● Attachment works with tube diameters: 0.75-2” ● Exit velocity of soccer ball: > 15 ft/sec ● Weight of object thrown (soccer ball): 15 oz ● Incoming capture angles: +/- 45 degrees ● Turning radius extension: ? in

* Constraints: List any external factors that limit the selection of alternatives, e.g., allowable footprint, budget, required use of legacy hardware/software.

● Does not interfere with mobility aid function ● Final market cost of $500-1200 ● Aesthetically pleasing ● Fun ● Safe ● Meets requirements for attachment to Class I devices ● Lightweight

* Project Deliverables: Minimum requirements: ● All design documents (e.g., concepts, analysis, detailed drawings/schematics, BOM, test

results) ● working prototype ● technical paper ● poster ● All teams finishing during the spring term are expected to participate in ImagineRIT Additional required deliverables: † Budget Information:
