Upper Extremity Actuation
For early prototypes, I worked with materials often used to make custom fit orthotics. I integrated this with an actuator precisely sized for the desired range of motion and an early strapping concept. This was used for early user testing before CAD Modeling.
After doing initial testing with the mock up prototype, I switched to Solidworks modeling to integrate valves and electronics.
Pictured is the lower extremity exploded view.
After gaining fit validation and feedback, I made a second rev of the elbow device accommodating for increased ventilation and strapping improvements.
Rev.2 of the Elbow System included a fully integrated housing for electronics, valves, and actuation. Cut outs reduce the weight of the device and improve breathability, reducing heat.
Strapping was designed to be easily detachable while still comfortable and effective. The latest strapping configuration was made to simulate wrapping. This was influenced by research done to find the lines of non-extension at the skin's surface.
Lower Extremity Actuation
This image depicts two adults, one in the 5th percentile and the other in the 95th percentile. The hug wall needed to be designed to accommodate both.
The Hug Wall was designed through an iterative process. Pictured was a later version, integrated with asbestos gloves, high clarity mylar, and polyethelyene sheeting.
This bellows style hug wall was designed to have a high range of motion and retract back into the wall. It was created using a laser welded bellows structure.
