S-Shaped Flexible Back Support for Mobility and Lateral Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current back braces for emergency medical technicians (EMTs) limit mobility and cause discomfort by locking the back muscles and spine in one position, increasing the risk of back injuries from heavy lifting.
Innovation Solution
A back support system with a flexible support shaped like an 'S' to mimic the spine, coupled with a brace portion that adjusts to the wearer's bending motion and includes ribs to inhibit lateral movement, providing support while allowing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid back brace is used to support the spine, then spinal stability is improved, but mobility and comfort deteriorate
Solution Approach 1:
The back support system uses a flexible support member instead of a rigid structure, allowing the brace to dynamically adapt to spinal movements while maintaining support. The flexible material enables the device to move with the spine during bending and twisting motions, providing stability without restricting mobility.
Solution Approach 2:
The patent changes the physical parameter of the support structure from rigid to flexible. By selecting materials with appropriate elastic properties and adjusting the flexibility parameters, the device achieves optimal balance between spinal support and movement freedom, resolving the contradiction between stability and mobility.
2Ease of operation
If a flexible support is used to allow movement, then mobility is improved, but lateral stability deteriorates
Solution Approach 1:
The patent introduces ribs as transverse elements extending from the flexible support member. These ribs add structural reinforcement in the lateral dimension without compromising the flexibility needed for forward and backward movement. The ribs prevent excessive lateral bending while allowing natural spinal motion in the sagittal plane.
3Stability of the object's composition
If the back brace locks the spine in one position, then spinal support is improved, but discomfort and restriction increase
Solution Approach 1:
The flexible support member continuously adapts to the wearer's movements, providing dynamic support rather than static locking. This allows the spine to move naturally while maintaining proper alignment, eliminating the discomfort caused by rigid immobilization while still providing necessary spinal support.
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
The system maintains spinal alignment and reduces the risk of back injuries by supporting the spine during heavy lifting, while allowing natural movement and comfort.
Implementation Method 1
a flexible support formed in the shape of a portion of a spine of a person, the flexible support extending in an 'S' shape corresponding to the shape of the spine
Implementation Method 2
a brace portion coupled to the flexible support proximate ends of the flexible support, the brace portion adapted to force the spring portion toward the spine as a wearer bends
Implementation Method 3
at least one rib extending between the flexible support and the brace portion
