Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wound dressings struggle to effectively cover long, nonlinear, or non-planar skin traumas due to lack of conformability and adequate support, often requiring multiple dressings and leading to poor coverage and contamination risks.

Innovation Solution

A wound dressing with an elongated composite and a delivery system featuring multiple disconnected support networks that enhance handling and flexibility, allowing for seamless application over complex wound surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single large dressing is used to cover long nonlinear traumas, then complete wound coverage is achieved, but handling and application become difficult

Engineering Contradiction:

Improvewound coverage areaVSAvoidhandling ease

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The support layer is divided into multiple disconnected support networks distributed across the dressing. Each support network is a separate structure that provides localized support, allowing the dressing to be handled in sections while maintaining overall structural integrity for complete wound coverage.

Inventive Principle:

Principle #1Segmentation

2Area of stationary object

If dressings of greater size are used to cover long traumas, then complete coverage is achieved, but handling becomes difficult

Engineering Contradiction:

Improvewound coverage areaVSAvoidhandling ease

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

3Area of stationary object

If multiple dressings are used to cover long traumas, then coverage is achieved, but application time increases

Engineering Contradiction:

Improvewound coverage areaVSAvoidapplication time

Core Design Contradiction:

Area of stationary objectVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

4Ease of operation

If traditional dressings are used on nonplanar surfaces, then application is simple, but conformability is inadequate

Engineering Contradiction:

Improveapplication simplicityVSAvoidconformability to nonplanar surfaces

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The dressing incorporates a flexible substrate with integrated support networks that can bend and conform to nonplanar body surfaces. The support networks are designed to flex with the dressing while maintaining structural integrity, enabling adaptation to curved and irregular wound locations.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The support networks are designed with dynamic characteristics that allow them to adapt to different surface geometries. The disconnected nature of the support networks enables independent movement and flexing, allowing the dressing to dynamically conform to nonplanar surfaces during application and wear.

Inventive Principle:

Principle #15Dynamics

5Shape

If dressings are cut and customized for nonlinear traumas, then better fit is achieved, but application complexity increases

Engineering Contradiction:

Improvedressing shapeVSAvoidapplication complexity

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation
