Solution Overview

Problem

Existing hair coloring technologies require a two-component system with hydrogen peroxide and dye precursors, leading to inefficiencies such as wasted product, damage to hair, and inability to achieve consistent color due to the need for separate containers and the use of potentially damaging lightening agents.

Innovation Solution

A single-component stable dry powder hair coloring composition that includes a hydrogen peroxide liberating complex with polyvinylpyrrolidone and polyvinylpyrrolidone polymer, mixed with warm water to activate hydrogen peroxide, allowing for consistent and predictable coloration without the need for separate containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a two-component system with hydrogen peroxide and dye precursors is used, then permanent hair coloring is achieved, but product waste increases and device complexity increases

Engineering Contradiction:
Improvepermanent hair coloringVSAvoidproduct waste
Core Design Contradiction:
Duration of action of stationary objectVSLoss of substance

Solution Approach 1:

The patent combines hydrogen peroxide and dye precursors into a single stable dry powder composition. The hydrogen peroxide is incorporated as a solid adduct or complex that remains stable in the dry state but releases active peroxide upon contact with water during application. This merging eliminates the need for separate containers and prevents waste from unreacted dye stuff in the second container.

Inventive Principle:
Principle #5Merging (Combining)

2Duration of action of stationary object

If a two-component system with separate containers is used, then permanent hair coloring is achieved, but device complexity and storage requirements increase

Engineering Contradiction:
Improvepermanent hair coloringVSAvoidseparate containers
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The invention merges the two separate containers into one by incorporating both the hydrogen peroxide (in stable form) and dye precursors into a single dry powder composition. This single container can be stored indefinitely and mixed with water at the time of use, eliminating the complexity of managing two separate containers and their respective storage requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent changes the physical state and stability parameters of hydrogen peroxide by converting it from an unstable liquid to a stable solid adduct or complex. This parameter change allows the peroxide to be stored in a single container with dye precursors without premature decomposition, while still releasing active peroxide when needed.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If traditional lightening agents like urea or sodium percarbonate are used, then single component system is achieved, but hair damage increases

Engineering Contradiction:
Improvesingle component systemVSAvoidhair damage
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical form of hydrogen peroxide from unstable liquid to stable solid adduct, enabling single-component formulation without compromising peroxide stability. This allows the use of gentle peroxide-based lightening rather than harsh alternatives like urea or sodium percarbonate, reducing hair damage while maintaining single-component simplicity.

Inventive Principle:
Principle #35Parameter changes
