Back Orthosis Guiding Module to Prevent Belt Slipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back support belt systems suffer from complex structures that make application difficult, leading to misuse and unintentional slipping, especially during movement, and fail to adequately adapt to individual anatomical conditions.
Innovation Solution
A back orthosis design featuring a pelvic belt with adjustable shoulder belts and a guiding module composed of interconnected guiding and connecting elements forming a variable rhombus shape, allowing for easy application and preventing slipping by adapting to body movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid design with support elements and belts is used to achieve support effect, then the support effectiveness is improved, but the complexity of application increases and individual adaptation becomes difficult
Solution Approach 1:
The back support belt system is divided into a pelvic belt and two independent shoulder belts that can be applied and adjusted separately. This segmentation simplifies the application process while maintaining the rigid support structure needed for effectiveness.
Solution Approach 2:
The shoulder belts are designed to be independently adjustable in length and tension, allowing dynamic adaptation to individual anatomical conditions. This enables customization without increasing overall system complexity.
2Reliability
If pre-tensioned shoulder belts are used to provide sufficient support, then the support effect is improved, but the belts pull the pelvic belt unfavourably upwards during application, preventing functional fit
Solution Approach 1:
The pelvic belt is designed to be applied first and secured before the shoulder belts are attached and tensioned. This preliminary action prevents the pelvic belt from being pulled upward during the subsequent application of pre-tensioned shoulder belts.
Solution Approach 2:
The application process is segmented into distinct steps: first securing the pelvic belt, then independently adjusting and attaching the shoulder belts. This sequential approach eliminates the conflicting forces that would otherwise prevent proper fit.
3Reliability
If the back support belt system is designed with fixed structure to maintain stability, then the support reliability is improved, but unintentional slipping occurs during movement
Solution Approach 1:
The independent shoulder belts are designed with adjustable tensioning mechanisms that allow them to adapt dynamically to body movements. While maintaining stable support through their rigid structure, they can be repositioned and re-tensioned to prevent slipping during various activities.
Solution Approach 2:
The belt system allows for adjustment of key parameters such as belt length, tension, and positioning. These parameter changes enable the fixed structure to adapt to different movement phases and anatomical variations, preventing slipping while maintaining stability.
