Solution Overview

Problem

Hair greying, a significant sign of aging, is challenging to address with existing hair care products, as they often involve aggressive chemical treatments that are damaging and require frequent recoloring, and there is a need for a solution that can naturally restore hair pigmentation.

Innovation Solution

A hair care active agent comprising taxifolin glucoside and N-acetyl tyrosine, which stimulates melanin synthesis, promotes the proliferation of hair follicle stem cells, and activates antioxidant defenses to reduce the density and proportion of grey and white hair.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical hair colors are used to cover grey hair, then hair pigmentation is restored, but hair damage and user intolerance increase

Engineering Contradiction:

Improvehair pigmentation restorationVSAvoidhair damage and user intolerance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses natural plant extracts (indigo, henna, and their derivatives) as intermediary substances to achieve hair pigmentation restoration without the harmful effects of chemical dyes. These natural compounds act as mediators that deposit color on hair while being gentler on the hair structure and scalp, thus resolving the contradiction between effective pigmentation restoration and minimizing damage/intolerance

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the chemical parameters of hair coloring by using natural compounds with different molecular structures and properties compared to synthetic dyes. The indigo and henna extracts provide color through natural pigmentation mechanisms that are less aggressive to hair proteins and scalp tissues, changing the parameters of color deposition from chemical aggression to natural gentleness

Inventive Principle:

Principle #35Parameter changes

2Reliability

If chemical hair colors are used to cover grey hair, then hair pigmentation is restored, but frequent recoloration is necessary

Engineering Contradiction:

Improvehair pigmentation restorationVSAvoidduration of color sustainability

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies preliminary conditioning and preparation steps before color deposition to enhance the longevity of natural pigmentation. The formulation includes ingredients that prepare the hair cuticle and cortex to better retain natural pigments, and the indigo-henna combination is applied in a sequence that ensures deep penetration and durable binding, reducing the frequency of recoloration needed

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If natural plant extracts are used for hair pigmentation, then hair damage is reduced, but pigmentation effectiveness may be insufficient

Engineering Contradiction:

Improvehair damage reductionVSAvoidpigmentation effectiveness

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent combines multiple natural plant extracts (indigo, henna, and their derivatives) in specific formulations to achieve synergistic effects. This merging of natural compounds provides sufficient pigmentation effectiveness while maintaining the gentle, non-damaging properties of natural ingredients, thus resolving the contradiction between reduced hair damage and adequate pigmentation effectiveness

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent creates composite formulations using natural plant extracts that combine the benefits of different botanical sources. The indigo-henna composite provides both color depth and durability, while the natural composition avoids the harsh chemicals that cause damage, achieving both effectiveness and gentleness through material composition

Inventive Principle:

Principle #40Composite materials
