Solution Overview

Problem

Current medical treatments for chronic wounds are limited in effectively targeting multiple biochemical pathways, leading to prolonged healing times and increased healthcare costs, with existing technologies often focusing on single modes of action such as antimicrobials, debridement, or hydration.

Innovation Solution

A topical pharmaceutical composition combining antimicrobial compounds like silver sulfadiazine, bacitracin, neomycin, polymixin B, zinc oxide, vitamin E, and Coenzyme Q10, which targets microbial contamination and enhances the host's ability to regenerate tissue, providing multiple pharmacological responses to promote wound healing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If single mode of action treatments (antimicrobials, debridement, or hydration dressings) are used, then the treatment is simple and cost-effective, but the healing efficacy is limited and often leads to wound stasis without effectively treating the wound

Engineering Contradiction:
Improvehealing efficacyVSAvoidtreatment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple pharmacologically active compounds with different modes of action into a single topical composition. The composition includes agents that target microbial biofilms, promote debridement, stimulate tissue regeneration, and provide hydration, thereby merging multiple treatment functions into one unified product that addresses multiple wound healing pathways simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The topical composition is designed to perform multiple functions simultaneously: it acts as an antimicrobial agent against biofilms, a debridement promoter through collagenase activity, a tissue regeneration stimulator via growth factors, and a hydration provider through dressing components. This multi-functionality allows a single treatment to address various aspects of wound healing that previously required separate interventions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple biochemical pathways are targeted with combination treatments, then the healing efficacy is improved and healing time is reduced, but the treatment complexity and cost increase

Engineering Contradiction:
Improvehealing speedVSAvoidtreatment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent integrates multiple pharmacologically active compounds into a single topical composition that can be applied as one treatment. The composition includes compounds with distinct modes of action targeting different wound healing pathways, thereby achieving accelerated healing through multi-pathway intervention while simplifying the application process to a single product rather than multiple separate treatments.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If aggressive debridement is used to remove dead tissue, then the wound cleaning is effective, but the host tissue damage is increased and healing is delayed

Engineering Contradiction:
Improvedead tissue removalVSAvoidhealing progression
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent employs compounds that modulate the debridement process by changing its parameters from aggressive mechanical removal to controlled enzymatic action. The collagenase and other compounds facilitate selective degradation of necrotic tissue while preserving viable tissue through controlled biochemical reactions, thereby achieving effective debridement with minimal damage to host tissue and reduced risk of healing delays.
