Project Goal

• To design a recreational aide for seniors with a
  manufacturing cost of under 20

4
Research

• Spoke to seniors regarding their
• leisure activities
• Interviewed Program
• Coordinators from the Cherryhill
• Healthy Aging Program
• Gathered information regarding arthritis
• and how it affects recreational activity
• from the London Arthritis society

5
Statement of Need

• Approximately 4 million Canadian adults suffer
  from arthritis, many of them seniors
• Arthritis in the joints of the hand is very
  common
• It is difficult for these affected seniors to
  perform recreational activities requiring
  extended periods of gripping

6
Design Requirements

• Our design needed to
• Relieve stress on the joints in the hand
• Be adaptable to a variety of objects
• Be durable enough to withstand outdoor and indoor
  use
• Remain within the cost constraint of a 20
  manufacturing cost

7
The E-Z Grip Glove

• Main Features
• Useful for a variety of objects
• Transfers load from finger joints to palm of hand
  using the main strap
• Main strap easily tightened using ratchet
• Components
• Base Glove
• Main Strap
• Ratchet
• Contact Pad
• Palm Liner

8
The E-Z Grip Glove

• The Main Strap
• Transfers gripping load from fingers to palm
• Attachment point for gripping pad
• Works in conjunction with the ratchet to make the
  gripping mechanism adjustable
• Material Selected
• Synthetic Leather

9
The E-Z Grip Glove

• The Base Glove
• Serves as the base of the design
• Attachment point for all other components
• Would ideally be manufactured in different sizes
  and for both hands in order to scale our design
• Material Selected
• Trioxon

10
The E-Z Grip Glove

• The Ratchet
• Allows the main strap to be adjustable
• The main strap can be tightened with one hand
• Extra long handle minimizes the force required to
  operate ratchet
• Material Selected
• Plastic

11
The E-Z Grip Glove

• The Contact Pad
• Main contact point between the object and the
  main strap
• Included to reduce wear
• Material Selected
• Synthetic Leather

12
The E-Z Grip Glove

• The Palm Liner
• Enhances grip of the base glove
• Increases durability
• Material Selected

Prototype Testing

• Play tested the prototype at the UWO racquet
  courts
• The prototype responded well to our tests

17
Prototype Evaluation and Recommendations

• Illustrates the concept well The glove does add
  sufficient gripping support
• Too much friction between main strap and finger
  webbing
• Ratchet ladder is too stiff and long
• Ratchet handle needs to be extended

18
Conclusion

• The performance of our prototype confirms the
  validity of our design
• Our projected manufacturing cost meets the
  required constraint
• We now need to rework the design incorporating
  what we learned from this prototyping phase.
