Solution Overview

Problem

There is a need for improved bandage and wound dressing systems that promote healing processes, treat and prevent bacterial infections, and enhance wound treatment compositions.

Innovation Solution

A wound care system comprising a detachable, resorbable layer with a hydrophilic foam and an active agent, such as K21, which includes a saturation indicator and a spray applied liquid for disinfection and pain relief, promoting wound healing and preventing infections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a bandage includes a wound covering portion and a base substrate, then the wound is covered and protected, but the system lacks advanced healing promotion and infection prevention capabilities

Engineering Contradiction:

Improvehealing promotion and infection preventionVSAvoidbandage structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional components into a single integrated bandage system: the wound covering portion, base substrate, detachable resorbable layer with active agents, and saturation indicator are merged into one cohesive structure that provides comprehensive wound care including protection, healing promotion, and infection prevention

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bandage is designed with multi-functionality to address various wound care needs simultaneously: it provides mechanical protection, delivers antimicrobial agents, promotes healing through active ingredients, monitors saturation levels, and offers pain relief, making it a universal wound treatment solution

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If a bandage is applied to cover and protect open wounds, then wound protection is achieved, but advanced wound treatment functions are lacking

Engineering Contradiction:

Improvebacterial infectionVSAvoidbandage composition

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent applies local quality by concentrating antimicrobial active agents specifically in the detachable resorbable layer that contacts the wound, rather than distributing materials uniformly throughout the entire bandage structure, providing targeted infection prevention where it is most needed

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The bandage utilizes composite materials including the combination of the base substrate, wound covering portion, and detachable resorbable layer containing active agents, creating a multi-material system that provides both structural integrity and advanced therapeutic functions

Inventive Principle:

Principle #40Composite materials
