Solution Overview

Problem

Current cosmetic moisturizers are inadequate in effectively removing impurities and oil from the skin while maintaining hydration, often causing skin irritation, having unpleasant textures, and being incompatible with various skin types.

Innovation Solution

The development of stable cosmetic compositions comprising cocamidopropyl betaine, glycerin, peg-120 methyl glucose dioleate, and sodium chloride, or Helianthus annuus seed oil, cetearyl ethylhexanoate, butylene glycol, dicaprylyl carbonate, and carbomer, which are applied topically to cleanse and hydrate the skin, addressing the limitations of existing products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If moisturizers are used to maintain skin hydration, then skin hydration is improved, but impurities and oil are not effectively removed

Engineering Contradiction:
Improveskin hydrationVSAvoidimpurities and oil accumulation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent combines moisturizing agents (humectants, emollients, occlusives) with cleansing agents (surfactants, exfoliants) into a single integrated composition. This merging allows the product to simultaneously remove impurities and oil while maintaining skin hydration, resolving the contradiction between cleansing and moisturizing functions that previously required separate products.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cosmetic composition is designed to perform multiple functions: cleansing (removing impurities and oil), moisturizing (maintaining hydration), and conditioning (improving skin texture). This multi-functional approach eliminates the need for separate cleansing and moisturizing steps, directly addressing the limitation of traditional moisturizers that cannot effectively remove impurities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If traditional moisturizers are used to increase skin hydration, then skin hydration is improved, but skin irritation occurs

Engineering Contradiction:
Improveskin hydrationVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent carefully controls the concentration and selection of active ingredients, using gentle surfactants and adjusting pH levels to be skin-friendly. By optimizing these parameters, the composition achieves effective cleansing and moisturizing without causing skin irritation, unlike traditional moisturizers that may contain irritating preservatives or fragrances.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If moisturizers are applied to maintain skin hydration, then skin hydration is improved, but unpleasant tactile properties occur

Engineering Contradiction:
Improveskin hydrationVSAvoidtactile properties
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses a composite formulation combining multiple types of moisturizing agents (humectants like glycerin, emollients like fatty acids, and occlusives like silicones) with cleansing agents. This composite approach creates a balanced texture that provides effective hydration without the heavy, greasy, or sticky feel associated with traditional moisturizers, as the cleansing components help regulate the tactile properties.

Inventive Principle:
Principle #40Composite materials
