Solution Overview

Problem

Cosmetic bubbling tablets face challenges in maintaining size limitations, achieving long-term use, and delivering a carbonic acid bubbling effect due to volatility and precipitation issues, which hinder the delivery of skin cosmetic effects.

Innovation Solution

A cosmetic kit comprising a bubbling tablet with a specific ratio of sodium bicarbonate, alpha-hydroxyl acid, crystalline alpha-hydroxyl acid, and a water-soluble lubricant, combined with skin water containing an aliphatic compound, emollient, surfactant, and carbonated water, optimized for delayed floating and enhanced carbonic acid concentration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a bubbling tablet is designed to float in skin water, then the tablet can be used for a long time, but the tablet size is limited by the container ejection portion

Engineering Contradiction:
Improveusage durationVSAvoidtablet size
Core Design Contradiction:
Duration of action of stationary objectVSVolume of moving object

Solution Approach 1:

The patent modifies the specific gravity of the tablet by adjusting the ratio of sodium bicarbonate to alpha-hydroxyl acid and adding crystalline alpha-hydroxyl acid, enabling the tablet to delay floating while maintaining a small size suitable for container ejection

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If carbonic acid is used for bubbling, then the bubbling effect is achieved, but carbonic acid evaporates to air rather than dissolving in skin water

Engineering Contradiction:
Improvebubbling effectVSAvoidcarbonic acid loss
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The patent changes the chemical parameters by using sodium bicarbonate and alpha-hydroxyl acid instead of direct carbonic acid, generating carbon dioxide bubbles in situ that dissolve in skin water to form carbonic acid, preventing evaporation loss

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes the phase transition from solid sodium bicarbonate and crystalline alpha-hydroxyl acid to gaseous carbon dioxide, which then dissolves in liquid skin water to form carbonic acid, maintaining the bubbling effect while preventing evaporation

Inventive Principle:
Principle #36Phase transitions

3Stability of the object's composition

If the tablet dissolves completely in skin water, then no precipitation occurs, but the bubbling capability may be reduced

Engineering Contradiction:
Improvesolution stabilityVSAvoidbubbling capability
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent optimizes the specific gravity and surface tension parameters of the tablet by controlling the ratio of sodium bicarbonate to alpha-hydroxyl acid and adding crystalline alpha-hydroxyl acid, enabling complete dissolution while maintaining high bubbling capability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite tablet formulation combining sodium bicarbonate, alpha-hydroxyl acid, and crystalline alpha-hydroxyl acid, where the components work synergistically to provide both complete solubility and sustained bubbling capability

Inventive Principle:
Principle #40Composite materials
