Solution Overview

Problem

Current personal care products are inadequate in effectively addressing signs of aging and inflammation in skin and hair, with a need for improved regenerative and anti-inflammatory agents.

Innovation Solution

A personal care composition incorporating a naringin:zinc complex with a 2:1 molar ratio, which is dispersed in a carrier, providing anti-inflammatory and regenerative benefits by reducing IL-1a levels and promoting cell repair.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional personal care products use single benefit agents like taurine, then the product formulation is simple, but the regenerative and anti-inflammatory effects are insufficient

Engineering Contradiction:
Improveregenerative and anti-inflammatory efficacyVSAvoidcomposition complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies composite materials by combining naringin and zinc oxide in a specific 2:1 molar ratio to form a composite personal care composition. This composite approach enhances both regenerative and anti-inflammatory effects compared to single benefit agents, while the specific stoichiometric ratio optimizes the benefits without excessive complexity

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent merges two distinct benefit agents (naringin and zinc oxide) into a unified composition that provides synergistic effects. The combination addresses multiple skin concerns simultaneously (regeneration and inflammation) while maintaining a relatively simple formulation approach through defined molar ratios

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If personal care products use higher concentrations of benefit agents, then the therapeutic effect is improved, but the risk of skin irritation and inflammation increases

Engineering Contradiction:
Improvetherapeutic effectVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by optimizing the concentration ratio of naringin to zinc oxide to a specific 2:1 molar ratio. This parameter optimization ensures therapeutic effectiveness while minimizing skin irritation, as the balanced composition provides synergistic benefits without excessive concentrations of individual agents that could cause irritation

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses zinc oxide as an intermediary substance that modulates the activity of naringin. This intermediary approach allows for enhanced therapeutic effects while zinc oxide's inherent skin-soothing properties help mitigate potential irritation from active ingredients

Inventive Principle:
Principle #24Intermediary (Mediator)
