Solution Overview

Problem

Cosmetic products with inorganic heat-generating agents agglomerate in the presence of water, causing an uncomfortable gritty feel on skin and hair, making them undesirable for use.

Innovation Solution

A composition comprising an anhydrous medium and an exothermic heating agent that initiates a reaction when exposed to water and subjected to cyclical mechanical motion, providing a temperature increase of 4-6 °C greater than manual mixing, using a brush with sonic oscillation to deliver water and mixing energy, preventing aggregation and ensuring even heat distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If inorganic heat-generating agents are used in cosmetic products, then temperature increase is achieved, but agglomeration occurs causing gritty feel on skin and hair

Engineering Contradiction:
Improvetemperature increaseVSAvoidgritty feel
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an organic heating agent as an intermediary substance that replaces inorganic heat-generating agents. This organic agent reacts with water to produce heat without causing agglomeration, thereby eliminating the gritty feel while maintaining the temperature increase effect. The organic heating agent acts as a mediator between the need for heat generation and the requirement for smooth application.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the chemical composition parameter from inorganic to organic heating agents. This parameter change fundamentally alters the reaction mechanism with water, producing heat without the agglomeration problems associated with inorganic agents. The composition formulation is modified to use organic compounds that maintain solubility and prevent particle aggregation.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If manual mixing is used, then application is simple, but temperature increase is insufficient

Engineering Contradiction:
Improveapplication simplicityVSAvoidtemperature increase
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The patent enables the composition to generate heat through self-service mechanism where the organic heating agent automatically reacts with water upon contact, producing temperature increase without requiring intensive manual mixing. The system uses the water already present in the cosmetic application to trigger the exothermic reaction, making the process self-sufficient and maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

3Temperature

If water is added to initiate exothermic reaction, then temperature increase is achieved, but agglomeration of inorganic agents occurs

Engineering Contradiction:
Improvetemperature increaseVSAvoidcomposition stability
Core Design Contradiction:
TemperatureVSStability of the object's composition

Solution Approach 1:

The patent changes the chemical nature of the heating agent from inorganic to organic, which fundamentally alters how the substance interacts with water. The organic heating agent maintains compositional stability in the presence of water while still undergoing exothermic reaction. This parameter change prevents the agglomeration issue that plagues inorganic agents when exposed to water.

Inventive Principle:
Principle #35Parameter changes
