Solution Overview

Problem

Existing cosmetic compositions fail to effectively address skin aging, wrinkles, reduced elasticity, and dryness due to insufficient inhibition of matrix metalloproteinases (MMPs), lack of moisture retention, and oxidative stress.

Innovation Solution

A cosmetic composition containing graphene quantum dots as an active ingredient, ranging from 1.0×10−7 to 30 wt%, which scavenges reactive oxygen species, inhibits MMP-1 expression, promotes type 1 procollagen and fibrillin synthesis, and enhances aquaporin-3 and hyaluronic acid synthase-3 expression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cosmetic compositions are used, then basic skin care functions are provided, but skin aging, wrinkles, and oxidative stress cannot be effectively inhibited

Engineering Contradiction:

Improveeffectiveness in preventing skin agingVSAvoidoxidative stress and MMP activity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces graphene quantum dots with specific physical and chemical parameters (size, surface functional groups, quantum confinement effects) that fundamentally change the interaction with skin cells and reactive oxygen species, providing superior antioxidant and anti-aging effects compared to conventional cosmetics

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent combines graphene quantum dots with specific cosmetic ingredients (vitamin E, hyaluronic acid, niacinamide) to create a composite formulation that synergistically enhances skin protection, moisture retention, and anti-aging properties beyond what individual ingredients can achieve

Inventive Principle:

Principle #40Composite materials

2Quantity of substance

If moisture retention is insufficient, then skin dryness and roughness occur, but adding more moisturizers alone cannot address the underlying oxidative damage

Engineering Contradiction:

Improvemoisture content in skinVSAvoidoxidative stress

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

Graphene quantum dots act as intermediaries that simultaneously scavenge reactive oxygen species and enhance moisture retention through their unique structure, preventing oxidative damage that would otherwise compromise the skin barrier and moisture retention capabilities

Inventive Principle:

Principle #24Intermediary (Mediator)

3Strength

If collagen degradation by MMPs is not inhibited, then skin elasticity is lost and wrinkles form, but conventional ingredients fail to sufficiently suppress MMP activity

Engineering Contradiction:

Improveskin elasticityVSAvoidMMP-mediated collagen degradation

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of reactive oxygen species (which activate MMPs) into a beneficial outcome by using graphene quantum dots to scavenge these species, thereby preventing MMP activation and collagen degradation while promoting new collagen synthesis

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
