Variables
Strengths & Limitations
Strengths
- +Addresses a significant challenge in prosthetic design (weight and retention).
- +Presents a practical and potentially cost-effective fabrication technique.
Limitations
The specific materials and fabrication methods used may be costly or require specialized equipment, limiting broader application.
Reliability & validity

Think critically
How might the internal structure of a hollow prosthesis affect its thermal insulation properties or its susceptibility to internal damage?
Design Principles
"Minimize mass in wearable devices through intelligent structural design and material application to enhance user comfort and functional performance."
The weight of prosthetic devices directly impacts user comfort, wearability, and the effectiveness of retention mechanisms. By optimizing material usage and structural design, designers can create more functional and less burdensome solutions for individuals with significant reconstructive needs.
What This Means for Your Design
Making the inside of a fake face hollow makes it much lighter, which helps it stay on better and is more comfortable for the person wearing it.
