Prosthesis Socket Frame With Textile Ventilation and Padding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prosthesis sockets made of fiber-reinforced plastics are heavy, limit moisture removal, and can cause skin irritation due to airtightness, while frame sockets are bulky and require large volumes.
Innovation Solution
A prosthesis socket with a frame composed of fiber-reinforced plastic and a textile bridging free spaces, where the textile is fixed to the frame to reduce material usage and provide ventilation and padding, using warp-knitted spacer fabric for additional support and air permeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If prosthesis sockets are made of fiber-reinforced plastics with closed walls, then structural integrity and support are improved, but weight increases and moisture removal is limited
Solution Approach 1:
The prosthesis socket is divided into a frame structure and separate textile components. The frame provides structural integrity while the textile components can be selectively positioned to provide padding and ventilation where needed, rather than using solid closed walls throughout.
Solution Approach 2:
Different regions of the prosthesis socket have different properties: the frame provides structural support in areas requiring strength, while textile components provide padding and ventilation in areas requiring comfort and moisture management. This local differentiation optimizes both strength and weight.
2Reliability
If prosthesis sockets are made airtight, then sealing effect is improved, but moisture removal is limited and skin irritation increases
Solution Approach 1:
The textile components used in the prosthesis socket are inherently porous and breathable, allowing moisture vapor to pass through while maintaining a sealing effect. This prevents moisture accumulation and skin irritation without compromising the reliability of the socket.
3Weight of moving object
If frame sockets are used to reduce weight, then weight is reduced, but volume increases and materials become bulky
Solution Approach 1:
The prosthesis socket combines a lightweight frame structure with textile components that provide necessary padding and ventilation. This composite approach reduces weight compared to solid plastic sockets while maintaining a compact volume by using materials efficiently.
4Ease of operation
If textile components are added to frame sockets, then ventilation and padding are improved, but manufacturing complexity increases
Solution Approach 1:
The frame and textile components are merged into a single integrated prosthesis socket structure. The textile components are positioned and secured within the frame during the manufacturing process, creating a unified product that is easier to manufacture than separate components while maintaining wearing comfort.
