Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional multi-layer bandaging is time-consuming, requires trained therapists, is costly, and often fails to maintain consistent compression due to layer misapplication or loosening, leading to inadequate treatment for patients with lymphedema and edema.

Innovation Solution

A compression bandage designed with an arched shape, allowing it to be wrapped helically, featuring a central longitudinal line with a varying or constant radius to fit the body's shape, incorporating cushioning in a single layer, and using hook and loop fasteners for secure application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional multi-layer bandaging is applied, then compression effectiveness is improved, but application time and complexity increase significantly

Engineering Contradiction:

Improvecompression effectivenessVSAvoidapplication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines multiple bandaging layers into a single integrated bandage structure with varying thickness zones. The bandage includes a first zone with greater thickness for initial compression and a second zone with lesser thickness for continued compression, eliminating the need for separate cushioning and compression layers while maintaining therapeutic effectiveness.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bandage is segmented into functional zones with different thickness characteristics. The first zone extends along a first portion of the longitudinal axis with greater thickness, while the second zone extends along a second portion with lesser thickness, allowing different compression characteristics in different regions of the same bandage.

Inventive Principle:

Principle #1Segmentation

2Reliability

If traditional multi-layer bandaging is applied, then compression effectiveness is improved, but the number of required materials and costs increase

Engineering Contradiction:

Improvecompression effectivenessVSAvoidmaterial consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges the functions of cushioning material and compression bandage into a single integrated structure. The varying thickness zones provide both cushioning and compression in one material, eliminating the need for separate cushioning layers that would otherwise be required in traditional multi-layer bandaging.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single bandage structure performs multiple functions simultaneously: the greater thickness zone provides cushioning and initial compression, while the lesser thickness zone provides continued compression. This multi-functional design replaces multiple specialized materials with one versatile bandage.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Stress or pressure

If traditional multi-layer bandaging is applied, then initial compression is achieved, but consistent compression maintenance deteriorates as body part reduces in size

Engineering Contradiction:

Improveinitial compressionVSAvoidcompression consistency

Core Design Contradiction:

Stress or pressureVSStability of the object's composition

Solution Approach 1:

The bandage is designed with dynamic compression characteristics through its varying thickness zones. As the body part reduces in size, the different thickness regions compress at different rates, allowing the bandage to adapt and maintain consistent compression pressure throughout the therapeutic process.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different zones of the bandage have different local properties - the first zone with greater thickness provides initial cushioning and compression, while the second zone with lesser thickness provides sustained compression. This local differentiation ensures consistent compression maintenance as the body part changes size.

Inventive Principle:

Principle #3Local quality

4Reliability

If traditional multi-layer bandaging is applied, then compression therapy is provided, but proper application requires trained therapists

Engineering Contradiction:

Improvetherapy effectivenessVSAvoidapplication ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The bandage's varying thickness zones are designed to self-align and self-adjust during application. The greater thickness zone naturally positions itself to provide initial compression, while the lesser thickness zone automatically provides continued compression, reducing the need for trained therapist intervention and simplifying patient self-application.

Inventive Principle:

Principle #25Self-service

AI summary

The invention relates to a compression bandage adapted to be wrapped around a body part in a helicoidal manner. The compression bandage has a length (L) and a width (W) and the length (L) is several times greater than the width (W). On a section of the compression bandage, the central longitudinal line (15) of the compression bandage has an arched shape.
