Labyrinth Compression Garment for Uniform Leg Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure application garments fail to provide homogeneous and even pressure distribution around the legs of a subject, particularly for heavier individuals, leading to localized pressure points and an undesirable antero-posterior pressure gradient.
Innovation Solution
A compression slide with an inflatable arrangement featuring an active zone and a main inactive zone, designed to be wrapped around the leg, which includes securing means and an adjustable compression pocket, to ensure uniform pressure distribution by controlling fluid movement and avoiding pressure points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a compression garment uses a uniform compression structure, then the structure is simple, but it cannot provide homogeneous pressure distribution around the leg, leading to localized pressure points
Solution Approach 1:
The compression garment is divided into multiple independent compression units (first compression unit, second compression unit, third compression unit) that can be independently adjusted and inflated. Each unit targets specific regions of the leg (anterior, lateral, posterior aspects) to provide localized pressure control, eliminating pressure points while maintaining overall structural manageability
Solution Approach 2:
Different regions of the leg receive different compression pressures through independently adjustable compression units. The garment allows customization of pressure levels for each leg portion based on individual anatomical needs, ensuring homogeneous pressure distribution tailored to local requirements rather than applying uniform pressure everywhere
2Manufacturing precision
If a compression garment is designed for adjustable pressure, then pressure distribution can be optimized, but the device complexity increases due to multiple adjustment mechanisms
Solution Approach 1:
The compression garment utilizes an inflatable structure with air chambers that can be filled to predetermined pressure levels. This pneumatic system provides precise pressure control through simple inflation mechanisms, avoiding complex mechanical adjustment systems while achieving accurate and homogeneous pressure distribution around the leg
Solution Approach 2:
The garment employs adjustable fastening elements (straps with buckles, Velcro closures) that allow modification of compression parameters. These simple mechanical adjustments enable pressure optimization without requiring complex electronic or mechanical control systems, maintaining ease of use while achieving precise pressure control

AI summary
Compression slide (10) to be wrapped around a leg of a subject in order to apply a pressure around the leg. The leg of the subject has a back surface (Li) with main apex (A1) facing any support surface (S). The compression slide comprises an external layer (12) with securing means (14) to secure the compression slide around the leg, a compression pocket to be inflated and being configured to surround the leg in order to apply pressure on both the back and the front surface of the leg. The compression slide comprises one inflatable arrangement to be arranged on the back surface of the leg, with an active zone (to be inflated, a main inactive zone to be located on the main apex of the back surface of the leg and to remain deflated when the compression pocket or the active zone are inflated.
