Multi-Layered Shoulder Orthosis with Adjustable Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoulder stabilizing devices often restrict the range of motion, making it difficult for athletes to continue playing sports safely after shoulder dislocation injuries until corrective surgery can be performed.
Innovation Solution
A multi-layered orthosis comprising a base harness with adjustable straps and an A/P strap, made of elastic material, that provides stability while allowing nearly full range of motion by securing the shoulder joint with hook-and-loop fasteners and strategically positioned anchor points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If existing shoulder stabilizing devices are used to stabilize the shoulder joint, then joint stability is improved, but range of motion is restricted
Solution Approach 1:
The orthosis is divided into multiple independent components including a base harness, anterior and posterior panels, multiple straps (anterior strap, posterior strap, A/P strap), and fastening devices. Each component can be independently adjusted and positioned to provide stability while allowing necessary movement for athletic activities.
Solution Approach 2:
The orthosis employs dynamic adjustment capabilities through multiple hook-and-loop fastener positions on the panels and straps, allowing the degree of stabilization and range of motion to be customized and modified based on the athlete's specific needs and activity requirements.
2Stability of the object's composition
If a rigid orthotic structure is used to stabilize the shoulder, then joint stability is improved, but comfort and adaptability to anatomical variations deteriorate
Solution Approach 1:
Different portions of the orthosis have different properties - the base harness provides foundational support, while the adjustable panels and straps provide localized stabilization at specific anatomical points. The hook-and-loop fasteners allow positioning at multiple locations to accommodate variations in shoulder anatomy and injury patterns.
Solution Approach 2:
The orthosis allows for parameter adjustments including strap tension, panel positioning, and fastener location to be changed based on the patient's anatomical variations, comfort requirements, and specific injury characteristics, transforming a fixed device into an adaptable system.
3Stability of the object's composition
If multiple straps and panels are used to provide comprehensive stabilization, then shoulder stability is improved, but device complexity increases
Solution Approach 1:
Multiple functional components (base harness, panels, straps, and fastening mechanisms) are merged into a single integrated orthotic system that works together to provide comprehensive shoulder stabilization while maintaining a cohesive and manageable structure.
4Ease of operation
If the orthosis is designed to allow full range of motion, then ease of operation is improved, but joint stability deteriorates
Solution Approach 1:
The orthosis employs dynamic adjustment capabilities through multiple hook-and-loop fastener positions on the panels and straps, allowing the degree of stabilization and range of motion to be customized and modified based on the athlete's specific needs and activity requirements.

AI summary
A multi-layered orthosis designed to stabilize the human shoulder joint. A base harness includes a shoulder enclosure, an anterior panel, and a posterior panel. An adjustable break separates free ends of the anterior and posterior panels which are distal to the shoulder enclosure. The base harness is applied to a patient by slipping the shoulder enclosure around the affected shoulder. Anterior and posterior straps are passed over the deltoid region of the affected shoulder and secured to the base harness. An additional large strap is placed over the anterior and posterior straps.
