Solution Overview

Problem

Curly hair products often fail to provide long-lasting curl definition and frizz control, requiring frequent reapplication and leading to product buildup, an unnatural feel, and a greasy sensation due to their inability to penetrate the hair fiber.

Innovation Solution

A hair care composition comprising organic acids, compounds with hydroxyl groups, amino acids, vegetal resins, and water, which penetrates the hair fiber without building up on the surface, providing long-lasting curl definition, frizz control, natural look, and desirable volume.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional curly hair products are applied to provide curl definition and frizz control, then curl definition and frizz control are improved, but product buildup, unnatural feel, and greasy sensation occur due to inability to penetrate hair fiber

Engineering Contradiction:
Improvecurl definition and frizz controlVSAvoidproduct buildup, unnatural feel, and greasy sensation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the product by incorporating specific organic acids (alpha-hydroxy acids like glycolic acid, lactic acid, citric acid; beta-hydroxy acids like salicylic acid), amino acids (arginine, lysine, histidine, cysteine), and vegetal resins (copaiba resin, lavender resin, tea tree resin) to alter the product's penetration capability and interaction with hair keratin, enabling effective curl definition without surface buildup

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite formulation combining multiple functional ingredients: organic acids for penetration and pH adjustment, amino acids for protein bonding and strength, vegetal resins for natural conditioning and frizz control, and hydrophilic compounds (propylene glycol, glycerin, ethanol) for hydration and distribution, achieving synergistic effects that provide curl definition without the harmful side effects of conventional products

Inventive Principle:
Principle #40Composite materials

2Reliability

If conventional products are applied to define curls, then curl definition is improved, but frequent reapplication is required due to short-lasting effect

Engineering Contradiction:
Improvecurl definitionVSAvoidduration of curl definition
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent modifies the chemical composition parameters by incorporating amino acids that bond with hair proteins and organic acids that penetrate deeply into the hair fiber structure, enabling the product to remain effective throughout the day without frequent reapplication, thus extending the duration of curl definition

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent ensures continuous effective action by formulating a product that penetrates and bonds with hair fibers, maintaining curl definition from application until the next wash, eliminating the need for frequent reapplication and providing lasting frizz control

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If large amounts of conventional product are used to achieve good combing and hair feel, then combing and hair feel are improved, but heavy aspect, wet look, and greasy sensation occur

Engineering Contradiction:
Improvecombing and hair feelVSAvoidheavy aspect, wet look, and greasy sensation
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical parameters by using hydrophilic compounds (propylene glycol, glycerin, ethanol) and lightweight vegetal resins that provide excellent combing and hair feel with minimal product quantity, avoiding the heavy aspect, wet look, and greasy sensation associated with conventional products

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies ingredients with specific local functions: organic acids for penetration and pH adjustment at the hair shaft, amino acids for protein bonding, vegetal resins for natural conditioning, and hydrophilic compounds for hydration and distribution, achieving optimal combing and hair feel without excess product buildup

Inventive Principle:
Principle #3Local quality
