Solution Overview

Problem

Existing insecticidal barriers, such as mosquito nets, face reduced efficiency due to insecticide degradation from sunlight and heat, and the high cost of synergists, which are necessary to counteract insecticide resistance and enhance efficacy.

Innovation Solution

A non-living insecticidal barrier with a first region containing a synergist and a second region containing insecticide, where the synergist is applied to a smaller area, such as the roof of a mosquito net, and the insecticide to the larger area, like the side walls, allowing for efficient contact and reduced overall costs by minimizing the amount of synergist and insecticide used.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If synergist is applied to the entire barrier, then insecticidal efficiency and resistance counteraction are enhanced, but costs increase significantly

Engineering Contradiction:
Improveinsecticidal efficiencyVSAvoidcost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The barrier is divided into two distinct regions: a first region containing both synergist and insecticide, and a second region containing only insecticide. This segmentation allows the expensive synergist to be applied only where most needed (first region) while maintaining overall effectiveness through the second region's contribution.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the barrier are given different compositions tailored to their specific functions. The first region has enhanced properties with synergist for maximum insecticidal activity, while the second region provides baseline protection with insecticide alone, optimizing resource allocation.

Inventive Principle:
Principle #3Local quality

2Reliability

If synergist is applied to larger area, then resistance counteraction is improved, but the amount of synergist and cost increase

Engineering Contradiction:
Improveresistance counteractionVSAvoidamount of synergist
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The synergist is applied partially to only the first region rather than the entire barrier surface. This partial action is sufficient to achieve the desired resistance counteraction effect, as insects contacting the first region receive the synergist boost, while the overall barrier effectiveness is maintained through the second region.

Inventive Principle:
Principle #16Partial or excessive action

3Quantity of substance

If insecticide is applied to smaller area, then cost is reduced, but insecticidal coverage and efficiency decrease

Engineering Contradiction:
ImprovecostVSAvoidinsecticidal coverage
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The barrier is segmented into regions with different insecticide formulations. The first region uses a combination of synergist and insecticide for enhanced local effect, while the second region uses insecticide alone for broader coverage, optimizing both cost and coverage effectiveness.

Inventive Principle:
Principle #1Segmentation

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

This configuration maintains high insecticidal efficiency while minimizing costs and environmental impact by ensuring that insects contact both synergist and insecticide, effectively breaking resistance and prolonging the barrier's effectiveness.

Implementation Method 1

the synergist may be very efficient, as illustrated in more detail in the following. An attempt to traverse the barrier will cause flying insects, especially mosquitoes, to contact several parts of the barrier during the search for passages in the barrier.

Implementation Method 2

the second region comprises an insecticide but no synergist for contact of the first region and the second region by a flying insect
