Solution Overview

Problem

Current treatments for rosacea are inadequate in effectively reducing redness and inflammation, and there is a need for improved methods to manage the symptoms and prevent progression of the disease.

Innovation Solution

The use of a redness-reducing polymetal complex, such as copper-zinc malonate, combined with moisturizers and other topical compositions like antimicrobial cleansers, anti-redness agents, and protective compositions, applied sequentially to treat rosacea, enhancing vasoconstriction and tissue penetration to improve symptom control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments (oral antibiotics and topical antibiotic gel) are used, then redness and papule formation are reduced, but the treatments do not provide sustained symptom management and require continuous use

Engineering Contradiction:
Improvesymptom control effectivenessVSAvoidduration of symptom management
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent changes the chemical parameters of the treatment by using polymetal complexes (containing metals such as copper, zinc, manganese, cobalt, nickel, or iron coordinated with ligands) instead of conventional antibiotic agents. This parameter change enables sustained symptom management and reduced redness with potentially longer-lasting effects, addressing the limitation of requiring continuous antibiotic treatment.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If laser treatments or IPL are employed to seal broken vessels, then blood flow to skin surface is prevented, but the procedures are invasive and require specialized equipment

Engineering Contradiction:
Improveblood flow to skin surfaceVSAvoidtreatment equipment complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical/optical system of laser and IPL treatments with a chemical system using polymetal complexes applied topically. The polymetal complexes achieve vasoconstriction and reduce blood flow to the skin surface through chemical action rather than requiring complex laser or light-pulse equipment, thereby eliminating the need for specialized medical devices.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Duration of action of stationary object

If topical treatments are used continuously to maintain symptom control, then rosacea symptoms are managed, but long-term use may cause skin irritation or resistance

Engineering Contradiction:
Improveduration of treatmentVSAvoidskin irritation
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent employs composite polymetal complexes where multiple metal ions are coordinated with organic ligands to create a synergistic formulation. This composite structure provides sustained therapeutic effect while potentially reducing skin irritation compared to single-agent treatments, as the complexed metals may have reduced reactivity while maintaining biological activity.

Inventive Principle:
Principle #40Composite materials
