Solution Overview

Problem

Existing eyebrow coloring compositions fail to provide long-lasting, high-quality tinting power and color staying power while being easy to use and non-irritating, with many temporary solutions lacking in retention and causing skin irritation.

Innovation Solution

A peel-off type eyebrow coloring composition using a double liquid crystal coating method with polyvinyl alcohol, polyvinyl pyrrolidone, dihydroxy acetone, and other ingredients to form an elastic coating film that penetrates deep into the skin, dries quickly, and maintains color for an extended period without irritation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a temporary eyebrow tint is used to provide easy application, then ease of operation is improved, but color staying power deteriorates

Engineering Contradiction:
Improveease of applicationVSAvoidcolor staying power
Core Design Contradiction:
Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The patent changes the chemical parameters of the coloring composition by using oxidative dyes (henna, indigo, black tea extract, coffee extract) that undergo chemical reactions with the hair and skin, transforming temporary surface coloring into semi-permanent penetration that lasts through the growth cycle, thereby resolving the contradiction between ease of application and color staying power

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite coloring system combining multiple natural dyes (henna, indigo, black tea, coffee) with oxidizing agents, where the synergistic interaction of these components enables both easy application as a cosmetic preparation and long-lasting color that persists through the eyebrow growth cycle

Inventive Principle:
Principle #40Composite materials

2Duration of action of stationary object

If an eyebrow tattoo is used to achieve long-lasting color, then color staying power is improved, but device complexity and difficulty of modification worsen

Engineering Contradiction:
Improvecolor staying powerVSAvoidcomplexity of procedure
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent employs a disposable cosmetic preparation that can be easily applied and removed, replacing the permanent tattoo procedure. The coloring composition is designed to last through the eyebrow growth cycle (providing semi-permanent results) but can be easily removed or allowed to fade, avoiding the complexity and irreversibility of tattoo procedures while maintaining long-lasting color

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

Solution Approach 2:

The patent changes the permanence parameter from permanent (tattoo) to semi-permanent (growth-cycle lasting), using oxidative dyes that penetrate and bind to hair and skin but can still be removed or faded, thereby reducing procedure complexity while maintaining extended color staying power

Inventive Principle:
Principle #35Parameter changes

3Duration of action of stationary object

If a conventional eyebrow pencil with oil-soluble film-forming agent is used to enhance retention, then duration of action is improved, but tinting power deteriorates

Engineering Contradiction:
Improveretention timeVSAvoidtinting power
Core Design Contradiction:
Duration of action of stationary objectVSManufacturing precision

Solution Approach 1:

The patent fundamentally changes the mechanism from surface film-forming to deep penetration and binding, using oxidative dyes that chemically interact with the hair and skin structure. This parameter change enables both strong tinting power (through deep penetration) and extended retention (through chemical bonding that lasts through the growth cycle)

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses a composite of multiple natural oxidative dyes (henna, indigo, black tea extract, coffee extract) that work synergistically to provide both intense tinting power through deep penetration and extended retention through chemical binding to hair and skin proteins

Inventive Principle:
Principle #40Composite materials

4Manufacturing precision

If a coloring composition that penetrates deep into the skin is used to improve tinting power, then tinting power is improved, but skin irritation worsens

Engineering Contradiction:
Improvetinting powerVSAvoidskin irritation
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by using natural oxidative dyes (henna, indigo, black tea, coffee) that are inherently gentler on the skin compared to synthetic dyes. These natural compounds penetrate deeply for strong tinting power while being less irritating, thus resolving the contradiction between tinting power and skin irritation

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent converts the potential harm of deep penetration (which could cause irritation) into a benefit by using natural compounds that penetrate deeply for strong tinting power while being biocompatible and less irritating, effectively converting the risk of deep penetration into an advantage of enhanced performance with reduced side effects

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
