Solution Overview

Problem

Existing topical compositions for skin and ocular regions contain harsh chemicals that irritate and dry the skin, disrupting the natural lipid barrier and causing increased dryness and irritation.

Innovation Solution

A non-irritating topical composition comprising plant-derived moisturizers, surfactants, anti-irritant agents, and hydrating agents in an aqueous vehicle, formulated to provide moisturization and cleansing without synthetic additives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If synthetic surfactants are used for cleansing, then cleansing effectiveness is improved, but skin irritation and lipid barrier disruption worsen

Engineering Contradiction:

Improvecleansing effectivenessVSAvoidskin irritation

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by replacing synthetic surfactants with plant-derived surfactants (such as decyl glucoside, cocamidopropyl betaine, and lauramine oxide). This substitution maintains cleansing effectiveness while eliminating the harmful effects of synthetic chemicals on the skin barrier, directly resolving the contradiction between cleansing power and skin irritation.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention uses composite formulations combining multiple plant-derived ingredients including surfactants, moisturizers, and anti-irritant agents. This composite approach creates a synergistic effect where the natural ingredients work together to provide effective cleansing while simultaneously protecting and nourishing the skin, thus overcoming the limitations of single-component synthetic surfactants.

Inventive Principle:

Principle #40Composite materials

2Reliability

If synthetic emollients are used for moisturizing, then moisturizing effect is improved, but pore clogging and contact allergy worsen

Engineering Contradiction:

Improvemoisturizing effectVSAvoidpore clogging

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the moisturizing agent parameters by substituting synthetic emollients with plant-derived alternatives such as vegetable glycerin, plant oils, and botanical extracts. These natural moisturizers provide adequate hydration without the comedogenic effects of synthetic emollients, thereby maintaining moisturizing reliability while eliminating pore clogging issues.

Inventive Principle:

Principle #35Parameter changes

3Strength

If harsh chemicals are used for skin protection, then protective barrier function is improved, but skin fragility and irritation worsen

Engineering Contradiction:

Improveprotective barrier functionVSAvoidskin fragility

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent converts potentially harmful harsh chemicals into beneficial natural plant-derived substances. By using plant-based ingredients with inherent protective properties, the formulation creates a protective barrier that strengthens the skin without causing the fragility and irritation associated with harsh chemical protectants. The natural ingredients provide protection while simultaneously nourishing and strengthening the skin barrier.

Inventive Principle:

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