Dorsal Lumbar Extension Brace Tensioning System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dorsal lumbar extension braces lack efficient and adjustable tensioning systems that allow simultaneous tightening of the waist and shoulder straps, limiting their adaptability to various patient sizes and indications.
Innovation Solution
A spinal brace with a waist portion, dorsal lumbar extension, and shoulder straps, featuring a cable tensioning system that enables simultaneous adjustment of the waist and shoulder strap tension through a cable and cable tensioner, allowing for modular fit and adjustable tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate tensioning mechanisms are used for the waist portion and shoulder straps, then each component can be adjusted independently, but the device complexity increases and requires more inventory sizes
Solution Approach 1:
The patent combines the tensioning mechanisms for the waist portion and shoulder straps into a single integrated cable system. The cable extends from the waist portion through the dorsal lumbar extension to the shoulder straps, allowing one tensioning action to simultaneously adjust both components. This merging reduces device complexity while maintaining independent adjustability through the modular cable path.
Solution Approach 2:
The cable tensioning system serves multiple functions simultaneously: it tensions the waist portion, tensions the shoulder straps, and allows both adjustments through a single operational mechanism. This multi-functionality enables one system to replace what would traditionally require separate tensioning devices for each component.
2Adaptability or versatility
If the brace is designed to fit a wide range of patient sizes, then inventory needs are reduced, but the tensioning system becomes less adjustable for specific patient indications
Solution Approach 1:
The patent implements dynamic adjustability through the cable tensioning system that can be modified during use. The cable path and tensioning points are designed to allow real-time adjustment of tension levels while maintaining the overall fit for the patient size category. This dynamic capability enables precise tension customization without requiring custom-manufactured braces for each patient indication.
