Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional cosmetics fail to effectively prevent skin aging and maintain skin barrier function due to material precipitation, recrystallization, and insufficient efficacy, leading to skin issues like dryness, atopic dermatitis, and psoriasis, especially with increased exposure to pollutants and oxidative stress.

Innovation Solution

A cosmetic composition containing low-molecular-weight collagen, collagen water, or collagen extract, combined with ingredients like caffeic acid, soybean-derived lysolecithin, and fermented herbal extracts, to enhance skin soothing, moisturizing, and barrier improvement, while removing dead skin cells and impurities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cosmetics containing collagen are used, then skin moisturizing and anti-aging effects are provided, but the raw materials precipitate or discolor due to recrystallization, reducing stability and efficacy

Engineering Contradiction:

Improvestability of cosmetic compositionVSAvoidrecrystallization of collagen

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by modifying the molecular weight parameter of collagen to low-molecular-weight collagen (molecular weight of 1,000 daltons or less). This parameter change prevents recrystallization and precipitation while maintaining moisturizing and anti-aging effects, thereby resolving the stability contradiction

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by combining low-molecular-weight collagen with other cosmetic ingredients such as humectants, emollients, and active compounds. This composite approach enhances overall formulation stability and prevents precipitation while maintaining efficacy

Inventive Principle:

Principle #40Composite materials

2Reliability

If conventional cosmetics are used, then skin protection function is provided, but they fail to improve skin barrier function fundamentally, leading to recurring skin diseases

Engineering Contradiction:

Improveskin barrier improvement effectVSAvoidskin diseases such as atopic dermatitis and psoriasis

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by using low-molecular-weight collagen with molecular weight of 1,000 daltons or less, which can penetrate deeper into the skin barrier and fundamentally improve barrier function rather than just providing surface protection. This enables treatment of underlying skin diseases

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses low-molecular-weight collagen as an intermediary substance that facilitates communication and interaction between skin layers, promoting regeneration and repair of the skin barrier. This intermediary action helps treat skin diseases by restoring barrier function

Inventive Principle:

Principle #24Intermediary (Mediator)

3Strength

If conventional cosmetics are used, then skin elasticity is provided, but they become ineffective after long-term exposure to ultraviolet rays and air, causing side effects

Engineering Contradiction:

Improveskin elasticityVSAvoidmaintainability of potency

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent applies parameter changes by using low-molecular-weight collagen with enhanced stability parameters that resist degradation from ultraviolet rays and air exposure. This maintains skin elasticity and potency over long-term use without causing side effects

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces unstable conventional collagen with stable low-molecular-weight collagen that does not require frequent replacement or reapplication, maintaining effectiveness throughout the product's shelf life and usage period

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
