Orthopedic Strap Eyelet Positioning for Pressure Point Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthopedic devices face challenges in achieving an optimal strap fit and course due to the fixed position of deflection eyelets, leading to pressure points and discomfort, especially with standard elements that cannot be individually adjusted.
Innovation Solution
Incorporation of a fastening device with a feed-through and a connection element featuring anchors that allow for adjustable positioning and replacement of deflection eyelets, enabling customizable strap configurations through additive manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the deflection eyelet position is fixed in the orthopedic device, then the device structure is simple and manufacturing is easy, but the strap course cannot be optimized leading to pressure points and discomfort
Solution Approach 1:
The connection element is inserted through a feed-through structure that is integrated into the dimensionally stable element. The feed-through acts as a housing that contains the connection element, allowing the deflection eyelet to be positioned at different locations along the connection element while maintaining a compact integrated structure.
Solution Approach 2:
The connection element can be positioned at different locations along the feed-through, and the deflection eyelet can be attached at various positions on the connection element. This dynamic adjustability allows optimization of the strap course for different body parts and wearers, transforming the fixed structure into an adaptable one.
2Adaptability or versatility
If standard dimensionally stable elements are used, then manufacturing cost is reduced and production is simplified, but individual adjustment to body parts is limited causing suboptimal strap positioning
Solution Approach 1:
The fastening device with feed-through and connection element is designed as a universal component that can be integrated into standard dimensionally stable elements. This universal design allows the same fastening mechanism to work with different body parts and configurations, providing individual adjustment capability without requiring custom-manufactured elements for each application.
Solution Approach 2:
The fastening system is divided into separate functional components: the feed-through integrated in the dimensionally stable element, the connection element that can be positioned and adjusted, and the deflection eyelet for strap attachment. This segmentation allows standard elements to be combined with adjustable fastening components, maintaining manufacturing simplicity while enabling customization.
3Object-affected harmful factors
If the strap course is non-optimal, then the device structure remains simple, but pressure points and pain occur for the wearer
Solution Approach 1:
The adjustable connection element and deflection eyelet positioning system provides a feedback mechanism where the strap course can be optimized based on wearer comfort and body shape. The ability to reposition the connection element along the feed-through and attach the deflection eyelet at different locations allows iterative optimization to eliminate pressure points and discomfort.
Solution Approach 2:
The position of the connection element along the feed-through and the attachment point of the deflection eyelet on the connection element can be varied as adjustable parameters. By changing these positional parameters, the strap course can be optimized to avoid pressure points and painful areas on the wearer's body.
