Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for cosmetic products that effectively protect and restore the skin's natural lipid balance, particularly in response to environmental and internal factors that disrupt skin homeostasis, such as dryness, pollution, and microbial exposure, while also being sustainable and derived from renewable sources.

Innovation Solution

A composition comprising 20-70% triglyceride-containing oil, 10-50% jojoba oil, 5-30% free fatty acids or their salts, and 5-25% squalene, which acts as a skin conditioning agent, providing a pleasant feel, replenishing sebaceous lipids, and offering high stability against oxidation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional emollients are used to protect and restore skin lipid balance, then skin protection and hydration are improved, but the ingredients may not be sustainable or environmentally friendly

Engineering Contradiction:

Improveskin protectionVSAvoidenvironmental impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the compositional parameters by using specific ratios of triglyceride-containing oils (75-95%), free fatty acids (5-20%), and squalene (5-15%), transforming conventional emollient formulations into a more biocompatible and environmentally sustainable composition that mimics natural skin lipids

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite emollient system combining multiple natural ingredients (triglyceride-containing oils, free fatty acids, and squalene) that work synergistically to restore skin lipid balance, replacing synthetic ingredients with a composite of biodegradable natural components

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If silicones are used in cosmetic formulations to provide appealing sensations and textures, then skin feel is improved, but environmental concerns increase

Engineering Contradiction:

Improveskin feelVSAvoidenvironmental scrutiny

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces persistent silicone ingredients with naturally derived, biodegradable components that break down harmlessly in the environment, using short-living natural oils and fatty acids that provide temporary but effective skin conditioning without long-term environmental accumulation

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent substitutes the mechanical smoothing effect of silicones with the biochemical compatibility of natural lipids, using triglycerides and fatty acids that integrate with skin's natural lipid matrix to provide conditioning through biochemical interaction rather than physical coating

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If skin is exposed to environmental factors such as pollution and UV radiation, then skin homeostasis is disturbed and lipid composition is altered, but protection against these factors is needed

Engineering Contradiction:

Improveenvironmental exposureVSAvoidskin lipid composition

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The patent applies a pre-formulated lipid composition containing antioxidants and lipid-replenishing ingredients before environmental damage occurs, creating a protective barrier that cushions the skin against upcoming exposure to pollution, UV radiation, and other environmental stressors

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent uses ingredients that enable the skin to restore its own lipid balance autonomously, with free fatty acids and squalene that are naturally incorporated into skin cells and sebaceous glands, allowing the skin's own metabolic processes to replenish and rebalance lipids without external intervention

Inventive Principle:

Principle #25Self-service
