Solution Overview

Problem

Existing compression garments are ineffective in providing targeted compression to subcutaneous fat, leading to tourniquet effects that obstruct blood and lymphatic vessel return, and fail to deliver sufficient pressure to treat conditions like venous insufficiency and edema effectively.

Innovation Solution

A tubular graduated compression garment with fuzzy longitudinal wales and elastomeric threads that create skin furrows, focusing compression deep into the subcutaneous fat while maintaining open veins for efficient fluid return, using a fabric construction that allows for breathability and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If traditional compression garments apply uniform pressure to the entire surface, then compression is provided to the skin, but tourniquet effects occur that obstruct blood and lymphatic vessel return

Engineering Contradiction:

Improvecompression forceVSAvoidtourniquet effect

Core Design Contradiction:

ForceVSObject-generated harmful factors

Solution Approach 1:

The compression garment divides the compression force into discrete focal points through the wale structure. The longitudinal wales create localized compression zones that are separated by spaces, preventing continuous circumferential compression that causes tourniquet effects. This segmentation allows compression to be applied at specific points without creating an obstructive band around the entire limb.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The garment provides non-uniform compression distribution where high compression is concentrated at the wale contact points with the skin, while adjacent areas have reduced or zero compression. This local quality variation ensures that compression is delivered precisely where needed to treat subcutaneous fat and edema without creating the continuous obstruction characteristic of tourniquet effects.

Inventive Principle:

Principle #3Local quality

2Stress or pressure

If compression garments apply sufficient pressure to treat venous insufficiency and edema, then therapeutic effect is achieved, but blood and lymphatic vessels become obstructed

Engineering Contradiction:

Improvecompression pressureVSAvoidvessel patency

Core Design Contradiction:

Stress or pressureVSReliability

Solution Approach 1:

The wale structure segments the compression pressure into discrete focal points rather than distributing it continuously. This allows high pressure to be applied at specific contact points to treat edema and venous insufficiency, while the spaces between wales prevent continuous circumferential compression that would obstruct vessel patency and cause tourniquet effects.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of applying continuous compression that obstructs vessels, the invention inverts the approach by applying discontinuous, focal compression through wales. This inverted strategy delivers therapeutic pressure to the subcutaneous tissue while deliberately leaving gaps that maintain vessel openness and prevent obstruction.

Inventive Principle:

Principle #13The other way round (Inversion)

3Force

If compression is applied to the skin surface, then edema is reduced, but the compression does not reach the subcutaneous fat effectively

Engineering Contradiction:

Improvecompression forceVSAvoidcompression depth

Core Design Contradiction:

ForceVSManufacturing precision

Solution Approach 1:

The rounded, fuzzy surface of the wales acts like a small sphere or curved surface that concentrates compression force deeper into the tissue. The curved geometry of the wale contact area focuses the mechanical force vertically into the subcutaneous fat layer, rather than distributing it horizontally across the skin surface, thereby achieving deeper penetration of compression force.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The wale construction combines multiple material properties including fuzzy outer surfaces for skin contact, elastic core materials for force generation, and structural support elements. This composite structure enables the wale to deliver focused deep compression while maintaining comfort and adaptability to the skin surface.

Inventive Principle:

Principle #40Composite materials

AI summary

A graduated compression garment is disclosed that includes a plurality of longitudinal fuzzy wales arranged to form a fabric with a plurality of transverse elastomeric threads under variable tension connecting the adjacent longitudinal fuzzy wales to deliver a first level of elastic compression distally on a limb and a gradually decreasing level of elastic compression as the limb increases in diameter proximally.
