Solution Overview

Problem

Conventional cosmetic impregnation members, such as sponges and polyurethane foams, suffer from issues like poor elasticity, damage susceptibility, inadequate impregnation capacity, and degradation due to external stimuli, leading to performance degradation and usability challenges.

Innovation Solution

A cosmetic material impregnation member formed of fabric with specific mesh structures and fiber yarns, allowing for adjustable release levels and enhanced supporting capacity, preventing leakage, and manufactured through heat sealing to ensure durability and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If sponge or polyurethane is used as impregnation member, then impregnation capacity is improved, but elasticity and supporting capacity are insufficient and durability is poor

Engineering Contradiction:

Improveimpregnation capacityVSAvoiddurability and supporting capacity

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The invention uses a composite structure combining fabric layers with specific mesh structures and a support layer, creating a hybrid material system that integrates the impregnation benefits of porous structures with the durability and elasticity of woven fabrics, resolving the contradiction between impregnation capacity and structural reliability

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The invention applies different mesh structures to different layers (first mesh structure in upper layer, second mesh structure in lower layer) and uses a separate support layer with fiber yarns, giving each local region specific properties optimized for its function: impregnation, support, and durability

Inventive Principle:

Principle #3Local quality

2Quantity of substance

If chemical process manufacturing is used for impregnation members, then impregnation capacity can be achieved, but manufacturing complexity increases and control over impregnation capacity and release level becomes difficult

Engineering Contradiction:

Improveimpregnation capacityVSAvoidmanufacturing complexity and control

Core Design Contradiction:

Quantity of substanceVSEase of manufacture

Solution Approach 1:

The invention controls impregnation capacity and release level by adjusting physical parameters of the fabric structure (mesh size, yarn density, layer configuration) rather than relying on chemical processes, enabling precise control through mechanical design parameters that are easier to manufacture and replicate

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention replaces chemical manufacturing processes with a mechanical weaving and assembly process, substituting chemical bonding and treatment with physical interlacing of fibers and layers, thereby simplifying manufacturing and improving control over the final product properties

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If sponge or polyurethane impregnation members are used, then liquid cosmetic material can be held, but vulnerability to external stimuli (oxygen, UV rays, oil, alcohol) causes degradation and contamination

Engineering Contradiction:

Improvecosmetic material retentionVSAvoidvulnerability to external stimuli

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The invention uses naturally porous fabric structures with controlled mesh sizes that provide physical retention of cosmetic materials through capillary action and surface tension, creating a barrier that is inherently resistant to chemical degradation from external stimuli like oxygen, UV rays, and cosmetics ingredients

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The fabric-based structure uses inert, stable materials that do not degrade over time or react with cosmetic ingredients, providing a durable, non-reactive containment system that maintains its integrity throughout the product lifecycle without suffering from the degradation issues of organic foams

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
