Solution Overview

Problem

Existing single-dose solid cosmetic compositions, such as soaps and shampoos, are often too large for efficient use, leading to significant waste and economic and ecological inefficiencies due to incomplete usage.

Innovation Solution

A solid cosmetic composition with a porosity greater than 20% by volume, featuring cavities that allow for a similar size and grip while reducing material usage and enhancing transformation into a liquid state upon contact with water.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the size and volume of solid cosmetic compositions are increased to provide good grip, then ease of operation is improved, but quantity of substance increases leading to waste and economic loss

Engineering Contradiction:
ImprovegripVSAvoidmaterial usage
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent applies porous materials by incorporating cavities within the solid cosmetic composition matrix, creating a porous structure that reduces overall material quantity while preserving external dimensions for good grip. The porosity allows the composition to use less substance while maintaining the same external volume and handling characteristics.

Inventive Principle:
Principle #31Porous materials

2Ease of operation

If the size and volume of solid cosmetic compositions are increased to provide good grip, then ease of operation is improved, but loss of substance increases leading to ecological and economic inefficiency

Engineering Contradiction:
ImprovegripVSAvoidwaste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

By creating a porous structure with cavities throughout the composition, the patent reduces the actual amount of cosmetic substance needed while maintaining the same external size for proper grip. This directly reduces substance loss and waste generation.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent applies partial action by providing sufficient cosmetic substance only for the actual cleansing need, rather than filling the entire volume with active material. The cavities represent the partial portion that is not filled, reducing overall substance quantity while maintaining functional effectiveness.

Inventive Principle:
Principle #16Partial or excessive action

3Quantity of substance

If porosity is increased to reduce material usage, then quantity of substance decreases, but structural integrity may be compromised

Engineering Contradiction:
Improvematerial usageVSAvoidstructural integrity
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The patent carefully designs the porous structure with controlled cavity distribution and size to reduce material quantity while preserving sufficient structural integrity for handling and use.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent applies local quality by strategically positioning and sizing cavities within specific regions of the composition, creating areas of varying density that maintain overall structural strength while reducing total material usage in less critical areas.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The composition achieves efficient use with less material, reduces waste, and provides better foaming and transformation properties, being both ecologically and economically advantageous.

Implementation Method 1

Porosity, as defined by the present invention, refers to all the voids of a solid material, the voids being able to be filled with fluids, in particular water, when the solid composition is brought into contact with an aqueous solution
