Limb Support Harness Weight Distribution Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional limb support devices often fail to distribute weight evenly, causing discomfort and are difficult to put on or take off due to their design.
Innovation Solution
A limb support device featuring a sling with adjustable upper and lower sections, a support harness with central back portion, securing straps, and support straps that disperse weight across the body, utilizing fasteners for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single strap or unequally weighted design is used in arm slings, then the device is simple in structure, but it places unwanted pressure on a particular area of the user's body and does not distribute weight equally
Solution Approach 1:
The support harness is divided into multiple straps (first support strap, second support strap, and at least one securing strap) that independently distribute weight across different body areas. This segmentation allows the weight to be dispersed rather than concentrated at a single pressure point, resolving the contradiction between structural simplicity and pressure distribution.
2Ease of manufacture
If a support device has only one main clasp, buckle, or fastener, then the device is simple to manufacture, but it is difficult for a user to put on or take off
Solution Approach 1:
The fastening system is segmented into multiple independent fasteners (first fastener, second fastener, and at least one additional fastener) distributed across different straps. This allows users to attach and detach the device at multiple points, making it easier to put on and take off compared to a single fastener design, while maintaining manufacturing simplicity through repeated use of standard fastener components.
3Device complexity
If weight is concentrated on one area of the body, then the device structure is simple, but it causes user discomfort
Solution Approach 1:
The weight distribution is transitioned from a single-point (one-dimensional) support to a multi-point distributed support across different body areas (shoulders, back, chest). By adding spatial dimensions to the support points, the device disperses weight across multiple areas, reducing discomfort while maintaining reasonable structural simplicity through modular strap construction.

AI summary
A limb support device. The device may include a sling having an upper and lower section, which may be configured to hold a limb. The device may further include a support harness having a central back portion, at least one securing strap, and two support straps. The support harness may be configured to disperse the weight of the limb. The at least one securing strap and support straps may be removably connected to the sling by fasteners.
