Orthopedic Brace Strapping System with Multi-Point Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orthopedic braces lack an effective strapping system that securely maintains the brace frame on the body, efficiently transfers loads from affected joints to more stable areas, and allows for easy tension adjustment and mounting/remounting.
Innovation Solution
A strapping system featuring a strap with multiple connection points and adjustable segments, utilizing a strap connection member and adjustment ring to securely attach and position the brace frame, allowing for customizable tension and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional strapping system is used to secure the brace frame, then the brace can be maintained on the body, but the load transfer efficiency is poor and the strapping system is difficult to adjust and remove
Solution Approach 1:
The strap is divided into multiple segments with connection points at different locations. The first connection point attaches to the brace frame, the second connection point attaches to the body, and the third connection point provides an adjustment and release mechanism. This segmentation allows independent adjustment of each segment while maintaining secure attachment, resolving the contradiction between securing effectiveness and ease of operation.
Solution Approach 2:
The strapping system incorporates adjustable connection points that allow dynamic reconfiguration of the strap path and tension distribution. The third connection point enables the user to adjust the strap length and positioning, transforming a static strapping system into a dynamic one that can be easily adapted and removed, improving both reliability and ease of operation.
2Device complexity
If the strapping system uses a simple single-point attachment, then the device complexity is low, but the load distribution area is limited and comfort is reduced
Solution Approach 1:
The strap path transitions from a simple linear attachment to a multi-dimensional configuration by introducing connection points on opposite sides of the brace frame and routing the strap around the body. This dimensional expansion increases the load distribution area across different body regions while maintaining relatively simple strap and connection point components, thus resolving the contradiction between device complexity and load distribution area.
3Ease of manufacture
If the strap path is fixed with limited connection points, then the manufacturing precision requirements are lower, but the adaptability to different body sizes and shapes is poor
Solution Approach 1:
The brace frame incorporates multiple connection points at standardized locations that can accommodate different strap configurations. These universal connection points allow the same brace frame to adapt to various body sizes and shapes by adjusting which connection points are used and how the strap is routed, while maintaining straightforward manufacturing processes with pre-drilled holes and attachment mechanisms.

AI summary
A strapping system for retaining a rigid support member of an orthopedic brace in a desired utilitarian position on a body of a wearer is provided which includes a strap having a first strap end, a second strap end and an intermediate strap point between the strap ends. The strap is operatively configured to follow a strap path having a first connection point, a second connection point and a third connection point sequentially positioned on the support member. The first strap end is attached to the first connection point and the strap extends from the first connection point around the body of the wearer to the second connection point where the intermediate strap point is attached thereto. The strap is redirected at the second connection point in an opposing direction and extends back around the body of the wearer to the third connection point where the second strap end is attached thereto.
