Self-Applying Arm Immobilizer with Hoop Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current arm slings are difficult for users to put on independently and can cause stiffness in the elbow, hand, and wrist when worn for extended periods due to limited movement.
Innovation Solution
An arm immobilizer with an elongated, flexible material and hook and fastener system, including a hoop-shaped component that allows for self-application and adjustable immobilization to restrict arm movement while allowing some mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional arm slings are designed to fully immobilize the arm, then injury prevention is improved, but user independence deteriorates
Solution Approach 1:
The arm sling incorporates a dynamic design that allows controlled movement within the immobilization structure. The arm can move forward and backward while still being supported, enabling users to perform activities like eating and grooming independently while maintaining injury prevention benefits.
2Stability of the object's composition
If traditional arm slings provide complete immobilization, then stability is improved, but joint stiffness worsens
Solution Approach 1:
The sling allows dynamic movement of the arm in forward and backward directions while maintaining lateral stability. This controlled mobility prevents joint stiffness in the elbow, hand, and wrist while preserving the stabilizing support needed for injury recovery.
3Reliability
If traditional arm slings are designed for maximum support, then injury protection is improved, but ease of application deteriorates
Solution Approach 1:
The arm sling is designed to be self-applied by the user without requiring assistance from another person. The configuration allows the user to independently put on and adjust the sling while maintaining proper positioning and support for injury protection.

AI summary
Arm immobilizers and related methods are disclosed. According to an aspect, an arm immobilizer includes an elongated, flexible material having a first end and a second end. Further, the arm immobilizer includes a first part of a hook and fastener material attached to the first end. The arm immobilizer includes a second part of the hook and fastener material being attached to a portion of the elongated, flexible material positioned at a predefined location between the first end and the second end. The arm immobilizer includes a hoop shaped component that defines an aperture and is attached to the second end. The hoop shaped component is sized for receiving the first end through the aperture such that the first end is foldable towards the predefined location between the first end and the second end for attachment of the first part to the second part of the hook and fastener material.
