Elastic Inelastic Lumbar Brace Adjustability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lower back braces either lack the necessary support for physical activities or are overly restrictive due to their inelastic nature, failing to provide a comfortable and adjustable solution that balances elasticity and stability.
Innovation Solution
A lumbar support brace with both elastic and inelastic portions, featuring an adjustable inelastic tightening system that allows users to customize the level of elasticity based on comfort and support needs, transitioning from a more elastic to a more inelastic configuration as required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inelastic brace is used to provide trunk stability and support, then the support effectiveness is improved, but the mobility and comfort are reduced
Solution Approach 1:
The brace incorporates an adjustable tightening system that allows the user to dynamically change the brace's properties between elastic and inelastic states. The tightening system can be adjusted to provide either a more compliant elastic state for mobility or a more rigid inelastic state for trunk stability, enabling the brace to adapt to different activity requirements.
2Ease of operation
If an elastic brace is used to provide comfort and mobility, then the ease of movement is improved, but the trunk stability and support are reduced
Solution Approach 1:
The brace utilizes a tightening system that changes the physical parameters of the brace material from elastic to inelastic through adjustment. By modifying the tension and compression forces applied to the elastic material, the brace transitions between providing comfort/mobility and providing support/stability, effectively changing its mechanical properties on demand.
3Adaptability or versatility
If a brace with both elastic and inelastic portions is created, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The brace is divided into distinct functional segments: an elastic lumbar support portion and an inelastic tightening system portion. This segmentation allows each component to perform its specific function independently, with the elastic portion providing comfort and the tightening system providing adjustability, while keeping the overall design relatively simple through clear functional separation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to adjust the brace's elasticity throughout the day for optimal comfort and support during various activities, providing enhanced mobility and relief without being overly restrictive.
Implementation Method 1
a lumbar support having an elastic portion that is sufficiently elastic such that the support and the portion can be adjusted to conform to a wearer's body

AI summary
Braces having elastic portions that can be made effectively inelastic, based on a level of comfort or support desired by a user, via an inelastic tightening mechanism are disclosed. Some contemplated braces have lumbar supports that are at made at least in part of an elastic material, and inelastic tightening systems that extend across the elastic material and can decrease the effective elasticity of the elastic material to provide greater support.
