Device Requirements

Before design prototyping, we developed a list of customer needs and wants to incorporate into our design. Along with each need and want is a metric with a goal to evaluate how successful our design is at meeting these requirements. These goals directed many of the design selections in our current prototype.

Device Components

ComponentDescription and function
Adjustable BarTension bar with 5 adjustable heights levels (6, 9, 12, 15, 18 inches) to facilitate body-weight resistance based exercises for various size users.
Resistance Bands4 latex resistance bands with lengths of 4.4ft and pull resistance of 10lbs, 20lbs, 30lbs & 40lbs. Equipped with a carabiner clip at both ends for attachment.
Padded TPE SurfacePadded surface of the board protects user from the forces applied toward body during exercise.

Closed-cell technology prevents absorption of sweat to make device easy to clean with standard cleansing wipe.

TPE material exhibits high coefficient of friction with skin to minimize slipping during exercise.
Rubber Spacing BackingRubber spacer backing prevents device from slipping across various common floor surface, and provides protection from floor damage from device.
Resistance Band Attachment PointsTwo locations for resistance band attachment points allows for various resistance based exercises while not overwhelming users with attachment points.
