Transcript of Orthotic Sports Insole

Purpose of an Insole
Support the body and maintain strong healthy feet
Used to prevent overuse injuries and stress fractures
Minimize the rate of ankle injury.
Feet are a crucial component; they are the foundation of a body
Allow walking, standing, and running
Current sport insoles are used provide improvement of the skeletal function.
Enhancement of the biomechanical performance and provide better gait movement.

Current Purpose of Insoles
Type of Insoles on the Market
For athletes, this provides the ability to know if an injury may be present instantly.
Design Specification for Insole
Sport Orthotic Insoles
Types of Insoles in the Market
Insoles that are developed and sold in stores.
Allow general support and cushion.
Improved versions of the original insole in order to provide better comfort in specific areas of the foot.
Insoles designed for specific personal features made from casts.

Sustainable Material
materials that are used throughout the consumer and industrial economy that can be produced without depleting non-renewable resources and without disrupting the established steady-state equilibrium of the environment and key natural resources
Compression Molding
Ethical Issues
Solidworks Design for Insole
Acceptable Risk?
The ability to measure gait constantly on a user.
Force Sensor Specifications
Analysis of Design
There are two main points of contact during a step cycle: the heel and the ball
Analysis Cont.
The force of the heel during heel strike phase is greater than force of heel during midstance
The force of the ball during toe-off is greater than the force of the ball during midstance.
With this information we get these conditions for a normal gait cycle:
Analysis Cont.
If those conditions are broken, then the user could possible have an injury (slight limp). This information can then be alerted to the user or medical staff.

Expected Results
We expect the the design to work for it's purpose
Go through hot melt extrusion process.
In order to create different hardness and colors for the insole.
Go through injection molding.
The pellets are melted, mixed, and guided through a tube to a pipe nozzle.
The pipe nozzle releases the melted material into a mold. Pressure is placed onto the clamping unit allowing the material to take shape and dry.

Compression Test
Allow a pushing force on the material.
Understanding of the amount of force that can be placed on the material.
Shear Test
Forces applied tangential or parallel to the surface of the material.
Shear forces could cause skin hardening and calluses that could break.
Try to reduce shear forces.
Waterproof Test
Test for material’s resistance to water.
Reduce electrical shock.
