Solution Overview

Problem

Cosmetic cases with mesh screens often become contaminated with oil and dirt from the user's skin, leading to the growth of microorganisms like bacteria, which can compromise the hygiene and effectiveness of the cosmetics.

Innovation Solution

A cosmetic case featuring a silver-plated knitted mesh screen made from a mixture of polyamide and polyurethane yarns, such as dorlastan, which provides antimicrobial properties to inhibit the growth of bacteria and maintain hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a mesh screen is used to cover the cosmetic, then controlled application and prevention of spillage is improved, but contamination with oil and dirt leading to microbial growth worsens

Engineering Contradiction:

Improvecontrolled applicationVSAvoidmicrobial contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The mesh screen is constructed from composite materials - specifically stainless steel wires coated with silver or copper. This combines the structural integrity and mesh function of the base material with the antimicrobial properties of the precious metal coating, achieving both controlled application and microbial prevention

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The invention changes the chemical composition and surface properties of the mesh screen by applying metal coatings. This parameter change transforms an ordinary mesh into an antimicrobial surface that actively prevents bacterial growth while maintaining the original mesh functionality

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a fine mesh screen is used to prevent powder spillage, then cosmetic containment is improved, but accumulation of oil and dirt on the mesh worsens hygiene

Engineering Contradiction:

Improvecosmetic containmentVSAvoidoil and dirt accumulation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention converts the mesh's tendency to accumulate oils and dirt into a benefit by coating it with antimicrobial metals. The same surface that would normally harbor bacteria is transformed into an antimicrobial barrier that kills or inhibits microbial growth, turning a hygiene problem into a solution

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of operation

If the applicator is stored above the mesh screen, then accessibility is improved, but contamination of the mesh screen from the applicator worsens

Engineering Contradiction:

Improveapplicator accessibilityVSAvoidcross-contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The antimicrobial mesh screen acts as an intermediary barrier between the applicator and the cosmetic product. Even when the applicator rests above or on the mesh, the coated surface prevents direct contamination transfer, mediating the interaction between these components to prevent cross-contamination

Inventive Principle:

Principle #24Intermediary (Mediator)

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 antimicrobial mesh screen prevents the growth of bacteria, ensuring the cosmetic case remains hygienic and effective over time, while allowing controlled application of cosmetics and reducing waste.

Implementation Method 1

The mesh screen is made from a fabric which possesses antimicrobial properties. Preferably, the mesh screen comprises silver plated knitted fabric. The coating of silver provides antimicrobial, particularly antibacterial properties which reduces or prevents growth of microbes, particularly bacteria on the mesh screen.
