Arm Compression Stocking Donning Frame for One-Handed Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with weakened or surgically compromised lymphatic systems face difficulties in donning arm compression stockings, particularly when using only one hand, as the process is cumbersome and challenging, especially in normal postures like sitting.
Innovation Solution
A donning aid with two parallel main struts connected by an arcuate bracket and a base frame with a planar support area for stable positioning on a tabletop, along with auxiliary struts to form a tunnel shape for easier stocking placement, and a securing mechanism to prevent displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional donning method is used, then the compression stocking can be put on, but the process is difficult and cumbersome for people with weakened lymphatic systems who must use only one hand
Solution Approach 1:
The patent introduces a donning aid as an intermediary device between the user and the compression stocking. This aid includes a support structure with a support area for placing on the arm and a contact area for anchoring to the table, making the donning process easier for users with limited hand mobility
Solution Approach 2:
The donning aid is divided into distinct functional components: main struts for structural support, auxiliary struts for additional stability, a support area for arm placement, and a contact area for table anchoring. This segmentation allows each component to perform its specific function efficiently
2Ease of operation
If the donning aid is placed on a tabletop without proper positioning, then it is easy to set up, but the aid may shift or move during use
Solution Approach 1:
The contact area is designed to be positioned on the table surface before the arm is placed on the support area. This preliminary anchoring action ensures the aid remains stable during the subsequent donning process, preventing shifting or movement
Solution Approach 2:
The contact area is extracted as a separate functional element from the support area, allowing it to be independently positioned and anchored to the table surface, thereby ensuring stability without interfering with the arm support function
3Reliability
If the compression stocking is pulled tightly during donning, then it provides proper compression, but it becomes difficult to put on, especially for users with limited hand mobility
Solution Approach 1:
The support area is designed to hold the arm in a horizontal, gravity-neutral position, eliminating the need for the user to lift or support their arm weight during donning. This creates an equipotential state where the arm can be easily positioned without additional force
Solution Approach 2:
The donning aid creates a simplified model of the donning process by providing a stable framework that guides the compression stocking onto the arm without requiring complex manual manipulation, effectively copying the essential function of proper compression application in an easier-to-execute manner

AI summary
The pulling aid has two main rods (2) which are arranged to each other by mutual distance in a parallel manner. The ends (2b) of the main rods are held at a base frame, and other ends (2a) of the mail rods are connected with each other by an arc-shaped clamp (4). The base frame for supporting on an edge seaming of an even surface has an even contact area and a contact surface for the arrangement at an edge. The even contact area is arranged in a distance to the main rods. The contact surface is angled from the contact area.
