Solution Overview

Problem

Existing compression bandages for lymphedema are time-consuming, require skilled clinicians, lack self-care capabilities, and provide inconsistent compression, impacting comfort and hygiene, while alternative garments are costly and difficult to adjust to changing limb sizes.

Innovation Solution

A compression garment with adjustable tension bands and shoulder straps, featuring trimmable and indicia-marked materials, allowing for customizable fit and compression levels, along with integrated pockets and measurement systems for precise adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If compression bandaging is used, then edema reduction is effective, but application is time-consuming and requires skilled clinicians

Engineering Contradiction:

Improveedema reduction effectivenessVSAvoidapplication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The compression garment is designed with self-adjusting features including elastic materials that automatically adapt to body contours, snap buttons for easy fastening, and no requirement for skilled clinician intervention. The garment applies compression therapy independently to the torso, eliminating the need for professional bandaging application while maintaining therapeutic effectiveness.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The garment utilizes elastic materials with specific durometer ranges (50-80) that provide consistent compression pressure (20-50 mmHg) automatically. The elastic properties of the material enable the garment to adapt to varying body shapes and sizes without requiring manual adjustment, changing the parameter of compression application from manual control to material-intrinsic control.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If compression bandaging is used, then edema reduction is effective, but self-care capability is not promoted

Engineering Contradiction:

Improveedema reduction effectivenessVSAvoidself-care capability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

3Force

If inelastic compression bandages are used, then compression is applied, but sustained therapeutic levels are not provided

Engineering Contradiction:

Improvecompression pressureVSAvoidsustained therapeutic compression

Core Design Contradiction:

ForceVSDuration of action of stationary object

Solution Approach 1:

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Instead of using inelastic materials that require external tension to provide compression, the invention uses elastic materials that inherently provide compression through their material properties. The elastic material's natural tendency to return to its original shape creates sustained compression pressure without requiring continuous external force or manual adjustment.

Inventive Principle:

Principle #13The other way round (Inversion)

4Reliability

If bandages are worn, then compression is provided, but comfort and hygiene are negatively impacted

Engineering Contradiction:

Improvecompression therapyVSAvoidcomfort and hygiene

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The garment uses a flexible elastic material construction that conforms to the body's natural contours rather than imposing a rigid structure. This flexible design allows for better breathability, moisture wicking, and overall comfort while maintaining the necessary compression therapy, thereby improving hygiene and comfort compared to traditional bandages.

Inventive Principle:

Principle #30Flexible shells and thin films

5Adaptability or versatility

If alternative wrap garments are used, then bandage replacement is provided, but sizing adjustments are complex and time-consuming

Engineering Contradiction:

Improvebandage replacement capabilityVSAvoidsizing adjustment complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #35Parameter changes
