Back Support Belt With Variable-Rhombus Guidance Against Slipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back support belt systems are difficult to apply, prone to slipping during movement, and fail to adequately adjust to individual anatomical characteristics, compromising comfort and effectiveness.
Innovation Solution
A back orthosis with a pelvic belt and shoulder straps featuring a guide module with articulating guide elements forming a variable rhombus shape, allowing straps to adjust to body movements without slipping, and incorporating elastic sections to manage tension and maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-tensioned shoulder straps are used to provide support, then the support effect is improved, but the pelvic belt is pulled upwards during application making proper fit impossible
Solution Approach 1:
The shoulder strap system is divided into two independent straps (right and left) that can be adjusted separately, rather than a single pre-tensioned unit. This segmentation allows the pelvic belt to be applied first without interference from strap tension, then the straps are independently adjusted to provide support without pulling the pelvic belt upward.
Solution Approach 2:
The shoulder straps incorporate adjustable tensioning mechanisms that allow dynamic adjustment after application. The straps can be tightened or loosened based on the wearer's needs without affecting the pelvic belt position, enabling the support effect to be optimized after the base fit is established.
2Stability of the object's composition
If rigid design with support elements is used to achieve supportive effect, then the support stability is improved, but individual adjustment to anatomical characteristics is insufficient
Solution Approach 1:
Different parts of the back orthosis have different levels of rigidity and adjustability. The pelvic belt provides a stable base with fixed positioning, while the shoulder straps incorporate multiple adjustment points and flexible tensioning mechanisms. This local differentiation allows the rigid pelvic belt to provide stable support while the adjustable straps adapt to individual shoulder and spine anatomy.
Solution Approach 2:
The shoulder straps serve multiple functions: they provide support, allow individual adjustment to anatomical variations, and can be tensioned independently. The adjustable design enables a single device to accommodate different body types and support requirements, making the orthosis universally applicable while maintaining individualized fit.
3Reliability
If complex design with multiple elements is used to provide comprehensive support, then the support effectiveness is improved, but the device becomes difficult to apply and misuse is almost impossible
Solution Approach 1:
The pelvic belt is designed to be applied first and secured before the shoulder straps are attached and tensioned. This preliminary action establishes a stable base that prevents migration during subsequent strap adjustment. The sequential application process simplifies the overall procedure by breaking it into manageable steps: first secure the pelvic belt, then independently adjust the shoulder straps.
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 design prevents slipping and maintains effective support throughout various movements, ensuring comfort and stability by adapting to body position changes and distributing load effectively.
Implementation Method 1
a guidance module associated with the shoulder straps, the guidance module comprising: a first guidance element, a second guidance element, a third guidance element, a fourth guidance element... wherein the third guide element and the fourth guide element cross over each other in the region of the dorsal central lower crossing point
Implementation Method 2
incorporating elastic sections to manage tension and maintain stability
