Adjustable Leg Support Assembly for Elevation and Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leg vertical support devices do not effectively promote healing and reduce swelling by providing inadequate elevation and airflow for comfort.
Innovation Solution
A leg support device comprising a lower frame with parallel arms, a pad, and an upper frame with flexible material for leg support, along with hinged supports that allow vertical adjustment and maintain parallel alignment, ensuring comfortable elevation and airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid support structure is used to maintain leg elevation, then structural stability is improved, but comfort and airflow are reduced
Solution Approach 1:
The patent applies flexible material covering the support structure, which allows airflow to pass through while maintaining the elevation and support function. This flexible covering resolves the contradiction by providing both structural stability and airflow permeability, preventing stagnation and promoting healing.
2Stability of the object's composition
If fixed positioning is used to maintain leg elevation, then positional stability is improved, but adaptability for different users is reduced
Solution Approach 1:
The patent incorporates adjustable components that allow the support structure to be modified for different leg lengths and positioning requirements. This dynamic adjustability enables the device to adapt to various users while maintaining stable elevation during use, resolving the contradiction between fixed positioning and adaptability.
3Device complexity
If simple support structure is used, then device complexity is reduced, but support effectiveness is worsened
Solution Approach 1:
The patent divides the support device into multiple functional components including adjustable supports, flexible covering material, and positioning mechanisms. This segmentation allows each component to perform its specific function effectively, ensuring reliable leg elevation and airflow while maintaining overall structural simplicity through modular design.

AI summary
A leg support assembly includes a lower frame including a pair of arms orientated parallel to each other. A pad is attached to the arms. An upper frame has an open end and an open central area. The open end is directed towards the pad. A plane of the upper frame is orientated parallel to a plane of the lower frame. A flexible material is attached to the upper frame and extends across the open central area. The flexible material supports an elevated leg of a person. A plurality of supports is attached to and extends between the upper and lower frames and retains the upper frame vertically above the lower frame. The plurality of supports is hingedly coupled to the lower and upper frames to allow lowering or raising of the upper frame relative to the lower frame.
