Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solid perfuming compositions for keratin materials, such as perfumed sticks and concrete, are not suitable for single-dose use, lead to repeated contact with the treated material, and result in waste due to degradation or rupture.

Innovation Solution

A solid perfuming cosmetic composition with a porosity greater than 60% and comprising cavities, allowing for a single-dose format that maintains good grip and provides direct, comfortable application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If solid perfuming compositions are made in traditional stick or concrete format, then they can be stored and transported, but they are not suitable for single-dose use and generate waste due to degradation or rupture

Engineering Contradiction:

Improvesingle-dose usabilityVSAvoidwaste generation

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The solid perfuming composition is divided into discrete single-dose units, each capable of being used once and then discarded. This segmentation eliminates the need for repeated use of the same composition, thereby preventing waste generation from degradation or rupture while maintaining reliability for single-use applications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention employs disposable single-dose solid compositions that are intended to be used once and then discarded. This approach accepts the short lifespan of each individual dose as a trade-off for eliminating waste generation, as each dose is fresh and hygienic without requiring long-term storage or repeated use.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Adaptability or versatility

If solid perfuming compositions are used in stick format requiring repeated contact, then they can be applied multiple times, but they are not hygienic and generate waste

Engineering Contradiction:

Improverepeated application capabilityVSAvoidhygiene issues

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The composition is segmented into separate single-dose units, each of which can be applied once and then discarded. This eliminates the hygiene issues associated with repeated contact with the same stick or concrete format, as each dose is fresh and does not require repeated use.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention uses disposable single-dose compositions that are applied once and then discarded, eliminating hygiene concerns associated with repeated contact. Each dose is fresh and hygienic, making it suitable for single-use applications without compromising adaptability.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Loss of substance

If solid perfuming compositions are made with high porosity to enable single-dose format, then waste is reduced and hygiene is improved, but the composition may lack structural integrity

Engineering Contradiction:

Improvewaste reductionVSAvoidstructural integrity

Core Design Contradiction:

Loss of substanceVSStrength

Solution Approach 1:

The solid perfuming composition utilizes porous materials with controlled porosity to achieve the single-dose format. The porous structure allows for reduced material density and improved waste reduction, while the controlled nature of the porosity maintains sufficient structural integrity for the composition to remain stable during storage and application.

Inventive Principle:

Principle #31Porous materials
