Solution Overview

Problem

Existing hair care products often damage hair and irritate the scalp, leave a sticky or crunchy residue, and fail to provide lightweight, natural-feeling styling benefits, especially for curly hair, while also lacking moisture and curl elongation.

Innovation Solution

A hair cosmetic composition comprising hydroxypropyl guar, xanthan gum, fatty alcohols, glyceryl esters, and plant-based oils, which are applied to provide curl definition, hydration, and frizz control without weighing the hair down, using a unique combination of ingredients in gel or emulsion form.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If film-forming polymers are used to provide protection and frizz control, then styling benefits and frizz reduction are improved, but the product becomes viscous and leaves a sticky or crunchy residue on the hair

Engineering Contradiction:
Improvefrizz controlVSAvoidhair feel
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the physical-chemical parameters of the formulation by using volatile silicones instead of high-concentration film-forming polymers. The volatile silicones evaporate completely, changing from a persistent coating to a transient conditioning agent, thereby eliminating sticky or crunchy residues while maintaining frizz control through a different mechanism.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts and removes the film-forming polymer component from the formulation. By eliminating this ingredient entirely and replacing it with volatile silicones, the sticky or crunchy residue problem is solved while retaining the essential frizz control and styling benefits through alternative ingredients.

Inventive Principle:
Principle #2Taking out (Extraction)

2Shape

If chemical treatments are used to alter hair color or shape, then styling benefits and appearance are improved, but the hair fibers and scalp are damaged

Engineering Contradiction:
Improvehair shapeVSAvoidhair damage
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent employs volatile silicones that function as temporary, short-lived conditioning agents. These ingredients provide immediate styling and frizz control benefits but then evaporate completely, leaving no long-term residue that could damage hair. This disposable approach allows repeated use without cumulative damage.

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

Solution Approach 2:

The patent substitutes chemical mechanisms (film-forming polymers, alkaline/acidic compositions) with a physical mechanism (volatile silicones that evaporate). This replacement eliminates the need for harsh chemical treatments while achieving similar styling outcomes through physical evaporation and temporary conditioning.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If heavy coating products are used to provide styling benefits, then frizz control and style hold are improved, but the hair feels weighed down and greasy

Engineering Contradiction:
Improvestyle holdVSAvoidhair weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent utilizes phase transition (evaporation) of volatile silicones to solve the weight problem. The ingredients start as liquid coatings that provide styling benefits, then transition to gas phase by evaporating completely. This phase change eliminates the weight and greasiness while the styling benefits are achieved during the temporary liquid phase.

Inventive Principle:
Principle #36Phase transitions

Solution Approach 2:

The volatile silicones act as temporary styling agents that fulfill their function and then disappear through evaporation. This disposable nature ensures no heavy residue remains on the hair, maintaining lightness and natural feel while providing adequate style hold during the active period.

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