Solution Overview

Problem

Current insecticide-based protective systems for vector-borne diseases are ineffective due to mosquito resistance, pose health risks, and are not comfortable for prolonged use, necessitating a chemical-free, comfortable, and effective alternative for preventing mosquito bites.

Innovation Solution

Development of non-toxic, environmentally safe textile materials with engineered structural and physical attributes that prevent mosquito bites without using pesticides, featuring microscopic pores and elastomeric yarns for comfort and flexibility, and a predictive model for designing bite-proof textiles based on mosquito anatomy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical insecticides are used for mosquito protection, then mosquito bite protection is achieved, but health risks and insecticide resistance develop

Engineering Contradiction:

Improvemosquito bite protectionVSAvoidhealth risks and insecticide resistance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical insecticide systems with a physical barrier system using ultrafine mesh fabric. The mesh structure mechanically blocks mosquito proboscis from penetrating through to the skin, eliminating the need for chemical substances and their associated health risks and resistance development.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a porous ultrafine mesh fabric with controlled pore sizes that are small enough to prevent mosquito proboscis penetration while maintaining breathability. The porous structure provides a physical barrier that is effective against mosquito bites without involving chemicals.

Inventive Principle:

Principle #31Porous materials

2Reliability

If chemical insecticides are applied to clothing, then mosquito protection is provided, but comfort and usability are reduced

Engineering Contradiction:

Improvemosquito protectionVSAvoidcomfort and usability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent substitutes chemical repellent treatments with a physical mesh barrier that provides mosquito protection without the need for chemical applications on skin or clothing. This eliminates the discomfort and usability issues associated with chemical repellents.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses a flexible ultrafine mesh fabric that can be integrated into clothing or used as a standalone barrier. The thin film structure provides effective mosquito protection while maintaining flexibility and comfort, allowing wearers to move freely without the restrictions imposed by chemical treatments.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If existing bite-proof clothing is used, then mosquito protection is achieved, but chemical exposure and environmental damage occur

Engineering Contradiction:

Improvemosquito protectionVSAvoidchemical exposure and environmental damage

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces chemical insecticide treatments on clothing with a purely mechanical physical barrier using ultrafine mesh. This eliminates chemical exposure to humans and environmental damage from pesticide production, application, and disposal while maintaining effective mosquito protection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a porous ultrafine mesh structure that provides mosquito protection through physical barrier properties alone, without requiring any chemical substances. This approach eliminates the harmful chemical exposure and environmental damage associated with conventional bite-proof clothing.

Inventive Principle:

Principle #31Porous materials

4Reliability

If permethrin-treated uniform is used, then mosquito protection is provided, but effectiveness declines with usage and laundering

Engineering Contradiction:

Improvemosquito protectionVSAvoidpermethrin content retention

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent replaces the chemically-based permethrin treatment system with a permanent physical barrier using ultrafine mesh fabric. The mesh structure provides consistent mosquito protection throughout the garment's lifespan without degradation from usage, laundering, or chemical breakdown, eliminating the effectiveness decline associated with permethrin treatments.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
