Solution Overview

Problem

Current skin products fail to provide comprehensive benefits such as moisturizing, protection from environmental pollutants, and anti-aging in a single formulation, often requiring multiple products and facing issues of ingredient incompatibility and lengthy purification processes.

Innovation Solution

A dermal composition comprising cationic nanoparticles, a film-forming ingredient, and a positively charged component that work together to create a protective, tightening layer on the skin, enhancing ingredient absorption and providing immediate and long-term benefits without lengthy purification steps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate skin products are used to achieve moisturizing, protection, and anti-aging benefits, then comprehensive skin benefits are achieved, but product complexity and ingredient incompatibility issues arise

Engineering Contradiction:
Improvecomprehensive skin benefitsVSAvoidproduct complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate skin care functions (moisturizing, protection from environmental pollutants, anti-aging) into a single integrated dermal composition. This is achieved by formulating a unified product containing film-forming ingredients, cationic ingredients, and antioxidants that work together synergistically, eliminating the need for multiple separate products and their associated compatibility issues.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The dermal composition is designed to perform multiple functions simultaneously: it forms a protective film on the skin, delivers active ingredients through nanoparticle carriers, provides antioxidant protection, and offers anti-aging benefits. This multi-functional approach allows a single product to replace several specialized products while maintaining effectiveness across all functions.

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

2Manufacturing precision

If nanoparticles are used to deliver active ingredients deeper into the skin, then ingredient absorption is improved, but lengthy and costly purification processes are required

Engineering Contradiction:
Improveingredient absorptionVSAvoidpurification process time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The nanoparticle formulation is designed to be self-stabilizing and self-delivering. The cationic nanoparticles naturally adhere to the negatively charged skin surface and hair follicles, providing inherent targeting and delivery capabilities without requiring complex external purification or stabilization steps. The formulation maintains stability and effectiveness through its intrinsic chemical properties rather than requiring extensive post-synthesis processing.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If tensioning agents are used to provide immediate wrinkle reduction, then cosmetic improvement is achieved, but user comfort and flexibility are reduced due to stiff film formation

Engineering Contradiction:
Improvecosmetic improvementVSAvoiduser comfort
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent modifies the physical and chemical parameters of the film-forming ingredients to achieve optimal balance between tightening effect and flexibility. By carefully selecting and formulating specific film-forming polymers and controlling their concentration, molecular weight, and cross-linking density, the composition provides sufficient skin tightening for cosmetic improvement while maintaining adequate flexibility for user comfort and natural skin movement.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The composition effectively delivers active ingredients, protects against pollutants, hydrates the skin, and reduces the appearance of wrinkles and fine lines, offering immediate and long-term improvements with a simplified manufacturing process.

Implementation Method 1

They produce a cationic charge that creates a positively charged electrostatic field that surrounds the skin... The positive charge created by applying the cationic composition attracts these harmful substances to the skin

Methodology Applied
Scientific EffectElectrostatic field: Electric Field

Implementation Method 2

Various substances in the air that cause damage to the skin are negatively charged... The positive charge created by applying the cationic composition attracts these harmful substances to the skin

Methodology Applied
Scientific EffectElectrostatic attraction: Ion Repulsion/Attraction

Implementation Method 3

Many skin products also include ingredients that form a film on your skin when they dry. This film acts like a barrier. It protects your skin from foreign materials and also helps keep your skin hydrated by stopping water from evaporating

Methodology Applied
Scientific EffectFilm formation: Coatings

Implementation Method 4

The first active ingredients adhere directly to the skin... cationic nanoparticles that penetrate into the skin pores. These nanoparticles continue to provide a cationic charge to the skin for some time after the composition is removed

Methodology Applied
Scientific EffectAdhesion: Adhesive
