Solution Overview

Problem

There is a need for effective, long-lasting, and easy-to-implement methods to neutralize viruses on frequently handled articles and surfaces without compromising their functionality or appearance, as existing solutions fail to provide sustained antiviral protection without affecting the surface's properties.

Innovation Solution

A fluid composition with a viscosity between 30 mPa·s and 40 Pa·s at room temperature, containing virucides such as monolaurin, lauric acid, lactoferrin, or essential oils, which forms a transparent coating that can be applied via spraying or printing, offering antiviral properties while maintaining the surface's original appearance and durability.

1Reliability

If a coating is applied to provide antiviral protection, then viral neutralization effectiveness is improved, but the surface appearance and functionality may be compromised

Engineering Contradiction:
Improveantiviral protection effectivenessVSAvoidsurface appearance degradation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent adjusts the viscosity parameter of the fluid composition to fall within a specific range (30-40 Pa·s at room temperature) to optimize coating formation. This parameter control ensures the coating provides effective antiviral protection while maintaining surface appearance and functionality, resolving the contradiction between protection effectiveness and aesthetic preservation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by combining virucides (such as monolaurin, lauric acid, lactoferrin, or essential oils) with specific fluid carriers and adhesion promoters. This composite approach creates a coating that delivers effective antiviral protection while the fluid matrix maintains the surface's original appearance and functional properties.

Inventive Principle:
Principle #40Composite materials

2Duration of action of stationary object

If higher concentrations of virucide are used to ensure sustained antiviral protection, then antiviral efficacy is improved, but the composition complexity and potential harm to surface properties increase

Engineering Contradiction:
Improveantiviral protection durationVSAvoidcomposition formulation complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent optimizes the concentration parameter of virucides within specific ranges (0.1-10% by weight, preferably 0.5-5%) and controls the fluid composition viscosity (30-40 Pa·s). These parameter optimizations achieve sustained antiviral protection over time while avoiding excessive formulation complexity and preserving surface properties.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses precursors of virucides that can be converted into active virucidal forms on the surface. This allows the coating to provide sustained antiviral protection through in-situ generation of active agents, reducing the need for high initial concentrations of complex virucide formulations.

Inventive Principle:
Principle #26Copying

3Reliability

If a protective coating is applied to neutralize viruses, then viral neutralization capability is improved, but the ease of application and surface functionality may be affected

Engineering Contradiction:
Improveviral neutralization capabilityVSAvoidapplication ease and surface functionality
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent optimizes the fluid composition viscosity to 30-40 Pa·s at room temperature, which provides optimal flow characteristics for easy application while ensuring the coating forms a uniform, effective protective layer. This parameter optimization enables simple application methods (spraying, printing, coating) without compromising antiviral capability or surface functionality.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses adhesion promoters as intermediary substances that facilitate the bonding between the fluid composition and the substrate. This ensures the coating adheres properly to provide effective viral neutralization while maintaining ease of application and preserving surface functionality through proper coating integration.

Inventive Principle:
Principle #24Intermediary (Mediator)
