Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wounds, particularly chronic and infected wounds, pose significant physical, emotional, and financial burdens due to poor healing and increasing antibiotic resistance, leading to prolonged healing times and increased morbidity and mortality.

Innovation Solution

Topical administration of aqueous compositions containing polyglucosamine or derivatized polyglucosamine, such as PAAG, at specific concentrations to treat wounds, including infected and non-infected wounds, to enhance healing and reduce bacterial load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antibiotics are used to treat infected wounds, then bacterial load is reduced, but antibiotic resistance develops

Engineering Contradiction:

Improveeffectiveness of wound treatmentVSAvoidantibiotic resistance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces polyglucosamine as an intermediary substance that disrupts bacterial cell membranes and prevents biofilm formation, providing an alternative mechanism to antibiotics for treating infected wounds without contributing to antibiotic resistance

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the therapeutic parameter from antibiotic-based treatment to polyglucosamine-based treatment, utilizing the unique properties of polyglucosamine including its ability to chelate metal ions and disrupt bacterial cell membranes at specific concentrations (50-1000 μg/mL)

Inventive Principle:

Principle #35Parameter changes

2Reliability

If conventional wound treatments are used, then healing occurs, but healing time is prolonged

Engineering Contradiction:

Improvewound healingVSAvoidhealing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies polyglucosamine in advance to prevent bacterial colonization and biofilm formation on wound surfaces, creating a protective environment that accelerates subsequent healing processes and reduces overall treatment time

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent employs sustained topical application of polyglucosamine at optimized concentrations to continuously inhibit bacterial growth and promote wound healing, maintaining therapeutic effectiveness throughout the healing process

Inventive Principle:

Principle #20Continuity of useful action

3Object-affected harmful factors

If high concentration of PAAG is used to treat infected wounds, then bacterial colonization is prevented, but treatment complexity increases

Engineering Contradiction:

Improvebacterial colonizationVSAvoidtreatment protocol

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines multiple therapeutic functions of polyglucosamine including antibacterial activity, biofilm disruption, metal ion chelation, and wound healing promotion into a single topical treatment protocol, simplifying the overall treatment approach despite the multiple mechanisms of action

Inventive Principle:

Principle #5Merging (Combining)
