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 sealing.

Innovation Solution

A wound dressing with an elongated composite and a delivery system featuring multiple support networks, including hubs and phalanges, allows for enhanced handling and flexibility, enabling conformability and resilience over non-planar 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 coverage area is improved, but handling and application difficulty worsens

Engineering Contradiction:

Improvecoverage areaVSAvoidhandling and application

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The support system is divided into multiple discrete support networks (first, second, third support networks) distributed along the elongated composite. Each support network includes hubs and phalanges that can be independently positioned, allowing the dressing to be handled in sections while maintaining overall coverage capability.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If multiple small dressings are used to cover long traumas, then handling is improved, but application time and sealing quality worsen

Engineering Contradiction:

ImprovehandlingVSAvoidapplication time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

Multiple support networks are integrated into a single elongated composite structure with continuous flexible substrate and therapeutic layer. This merging allows the dressing to be applied as one continuous piece over long traumas, reducing application time and improving sealing quality while maintaining the handling benefits of distributed support points.

Inventive Principle:

Principle #5Merging (Combining)

3Stability of the object's composition

If a rigid dressing structure is used to provide support during application, then structural stability is improved, but conformability to nonplanar surfaces worsens

Engineering Contradiction:

Improvestructural stabilityVSAvoidconformability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support networks are localized at specific positions (hubs medially nested along the width) while the flexible substrate and therapeutic layer provide continuous conformability. This local concentration of support structures provides stability during application while allowing the rest of the dressing to conform to nonplanar anatomical surfaces.

Inventive Principle:

Principle #3Local quality

4Adaptability or versatility

If an elongated flexible composite is used to improve conformability, then adaptability to nonplanar surfaces is improved, but structural support and handling stability worsen

Engineering Contradiction:

ImproveconformabilityVSAvoidstructural support

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The dressing combines a flexible substrate with integrated support networks made of different materials properties. The flexible substrate provides conformability to nonplanar surfaces, while the support networks with hubs and phalanges provide structural stability and handling support, creating a composite structure that achieves both properties simultaneously.

Inventive Principle:

Principle #40Composite materials
