Solution Overview

Problem

There is a need for a natural, effective, and well-tolerated human skin whitening agent that can reduce melanin synthesis and unify skin complexion, particularly for addressing regional hyperpigmentation and aging-related skin alterations.

Innovation Solution

An alcoholic extract of aerial parts of Anthyllis vulneraria, obtained through a process involving extraction with an alcoholic solvent, decantation, filtration, and final dilution, which induces the expression of SESN2 in melanocytes and keratinocytes, thereby inhibiting melanin synthesis and offering antioxidant and anti-aging benefits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional depigmenting substances are used, then depigmenting efficacy is achieved, but natural origin and skin tolerance are compromised

Engineering Contradiction:
Improvedepigmenting efficacyVSAvoidskin tolerance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of depigmenting agents by using plant-derived compounds (anthocyanins, flavonoids, phenolic compounds) instead of conventional synthetic substances. These natural compounds exhibit depigmenting activity while being gentler on the skin, thus resolving the contradiction between efficacy and tolerance.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs readily available plant materials (blueberries, blackberries, raspberries, mulberries, violet extracts) as depigmenting agents. These natural, biodegradable compounds provide effective depigmenting action without the long-term skin damage associated with conventional substances, achieving both efficacy and safety.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Object-affected harmful factors

If natural plant extracts are used for depigmentation, then skin tolerance is improved, but depigmenting efficacy is reduced

Engineering Contradiction:
Improveskin toleranceVSAvoiddepigmenting efficacy
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent creates a composite depigmenting formulation containing multiple natural plant extracts (blueberry, blackberry, raspberry, mulberry, violet) combined with specific concentrations of natural compounds. This composite approach synergistically enhances the depigmenting efficacy of natural extracts while maintaining their skin-friendly properties, thus resolving the efficacy-tolerance contradiction.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent merges multiple plant extracts rich in different types of natural depigmenting compounds (anthocyanins, flavonoids, phenolics) into a single formulation. This combination amplifies the overall depigmenting effect while preserving the gentle, skin-tolerant characteristics of natural ingredients.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If multiple extraction steps are performed, then extract purity is improved, but processing time and complexity increase

Engineering Contradiction:
Improveextract purityVSAvoidprocessing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent employs a systematic extraction process where plant materials are sequentially extracted with different solvents (water, ethanol, methanol) to isolate specific compound classes. Each extraction step targets specific compounds, achieving high purity separation of anthocyanins, flavonoids, and phenolic compounds while maintaining a manageable process flow.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the extraction process into distinct stages using different solvents and conditions for each plant material. This segmentation allows selective extraction of different compound types, achieving high purity while organizing the complexity into manageable, sequential steps that can be efficiently executed.

Inventive Principle:
Principle #1Segmentation
