Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current treatments for skin aging and urogenital issues associated with menopause, such as wrinkles, incontinence, and vaginal atrophy, are either ineffective due to side effects or require invasive surgical procedures, and there is a need for non-surgical alternatives that are safe and effective.

Innovation Solution

Topical compositions containing estradiol, estriol, hyaluronic acid, green tea extract, and optionally ascorbic acid or date palm extract, formulated for topical administration to improve skin elasticity, reduce wrinkle depth, and enhance urogenital function without systemic absorption, thereby addressing skin aging and urogenital issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If topical estrogen compositions are used to treat skin aging and urogenital issues, then skin thickness and elasticity are improved, but risk of systemic absorption and side effects increases

Engineering Contradiction:

Improveskin thickness and elasticityVSAvoidsystemic absorption and side effects

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The composition is designed to act locally on the skin and urogenital tissues without significant systemic absorption. The use of topical application ensures that the therapeutic effects are confined to the target area, providing local treatment while minimizing systemic exposure and associated side effects.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The composition includes a carefully selected base and vehicle system that acts as an intermediary to control the delivery and absorption of estrogenic compounds. This intermediary system ensures that the active ingredients remain localized at the application site while still providing therapeutic benefits.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If invasive surgical procedures are used to treat skin aging and urogenital issues, then treatment effectiveness is improved, but treatment complexity and recovery time increase

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidtreatment complexity and recovery time

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention replaces invasive mechanical surgical procedures with a topical chemical composition that delivers therapeutic effects through non-invasive application. This substitution eliminates the need for surgery, anesthesia, and extended recovery periods while maintaining treatment effectiveness.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The composition utilizes specific concentrations of estrogenic compounds (0.01-10% estradiol, 0.01-10% estriol) and supporting ingredients to achieve therapeutic effects through parameter optimization rather than invasive intervention. This allows effective treatment with minimal complexity.

Inventive Principle:

Principle #35Parameter changes

3Shape

If current topical treatments are used for skin aging, then wrinkle reduction is achieved, but skin firmness and elasticity improvement is insufficient

Engineering Contradiction:

Improvewrinkle reductionVSAvoidskin firmness and elasticity

Core Design Contradiction:

ShapeVSStrength

Solution Approach 1:

The composition merges multiple active ingredients with complementary mechanisms of action: estrogenic compounds for collagen synthesis and skin thickening, hyaluronic acid for hydration and volume, green tea extract for antioxidant protection, and ascorbic acid for collagen maturation. This combination addresses both wrinkle reduction and skin firmness/elasticity improvement simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The formulation uses a composite material approach by combining different types of ingredients (estrogenic compounds, polysaccharides, plant extracts, vitamins) in a synergistic formulation. Each component contributes unique properties that collectively enhance skin firmness, elasticity, and wrinkle reduction beyond what single ingredients could achieve.

Inventive Principle:

Principle #40Composite materials
