Solution Overview

Problem

Existing compression garments, particularly bandages and stockings, are difficult to apply correctly, often slip or loosen, leading to inconsistent compression, discomfort, and adverse skin conditions due to poor design and materials that hinder wound healing.

Innovation Solution

A compression garment system featuring a single fabric layer with a moisture-absorbent inner surface and wicking outer surface, incorporating elastic material for graduated compression, touch markers for alignment, and adjustable closures to ensure consistent and comfortable compression levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stress or pressure

If elastic bandages are wrapped tightly around the patient's limb to achieve necessary compression, then compression level is improved, but ease of operation deteriorates and reliability worsens due to difficulty in application, tendency to slip or loosen

Engineering Contradiction:
Improvecompression levelVSAvoidease of application
Core Design Contradiction:
Stress or pressureVSEase of operation

Solution Approach 1:

The compression garment is divided into multiple fabric layers (first fabric layer with moisture absorbent material, second fabric layer with wicking material) that can be separately manufactured and applied, making the overall system easier to handle and apply while maintaining compression effectiveness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The compression garment is pre-formed with the correct graduated compression gradient and moisture management properties before application, eliminating the need for manual wrapping and tensioning during application. The garment is ready-to-wear with compression already optimized for the specific limb section

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If compression stockings are made with uniform diameter to simplify manufacturing, then ease of manufacture is improved, but reliability deteriorates because the shape does not match the variation in limb shape

Engineering Contradiction:
Improveease of manufactureVSAvoidcompression consistency
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

Different sections of the compression garment have different fabric compositions and compression properties tailored to match the local anatomy of the limb. The garment includes varying densities of elastic material and different fabric layer combinations in different zones to provide graduated compression that matches limb shape variations

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The compression garment uses varying ratios of elastic to non-elastic material, and different fabric layer configurations in different sections to create a graduated compression gradient. The parameters of fabric composition, stitch density, and elastic content are changed locally to match limb morphology

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If compression garments are made from synthetic materials to provide necessary compression, then ease of manufacture is improved, but object-affected harmful factors worsen due to excessive moisture, heat, and skin irritation

Engineering Contradiction:
Improveease of manufactureVSAvoidskin environment quality
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The compression garment combines synthetic elastic materials with natural moisture-absorbent materials in a multi-layer fabric structure. The synthetic materials provide compression and elasticity, while the natural materials (such as cotton or bamboo) provide moisture absorption and breathability, creating a composite material system that delivers both compression and skin-friendly moisture management

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The fabric layers incorporate porous structures that allow moisture vapor transmission and air circulation. The porous fabric enables sweat and moisture to escape from the skin surface, preventing excessive moisture buildup while maintaining the compression function of the garment

Inventive Principle:
Principle #31Porous materials

AI summary

Various fabrics, compression garments and compression garment systems are described. Fabrics formed from wicking and absorbent materials provide effective compression and an improved environment next to a wearer's skin, which provides greater comfort and improved overall performance. Two and multi-layer compression garments are described. An outer layer may be formed with an opening having a closure and an elastic material joining the sides of the opening. This provides a first level of compression with the closure open and a second level of compression with the closure closed and also helps a user in applying the garment. A compression garment is disclosed including: a shaped fabric body; an opening extending over at least a part of the fabric body; an elastic material connected at both sides of the opening such that, in use, the elastic material tends to draw the sides of the opening together; and a closure configured to close the opening.
