Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current mosquito attractant formulations have limited effectiveness and often fail to ensure adequate consumption by target mosquitoes, hindering efficient mosquito control methods, particularly for Culex species.

Innovation Solution

A mosquito attractant formulation comprising 3-octanone, heptanal, benzaldehyde, sulcatone, octanal, nonanal, and decanal, which mimics the odour of chickens and enhances mosquito attraction, especially in the presence of carbon dioxide.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If current mosquito attractant formulations are used, then mosquito attraction is achieved, but the attractant effect is limited and diminishes rapidly over time

Engineering Contradiction:

Improveduration of attractant effectVSAvoidattractant effectiveness

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent uses a composite attractant formulation containing multiple chemical compounds (3-octanone, heptanal, benzaldehyde, sulcatone, octanal, nonanal, and decanal) that work synergistically to provide sustained and reliable mosquito attraction, overcoming the limited duration of action of single-component attractants

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent optimizes the concentration ratios of individual components within the formulation to enhance the overall attractant effect and extend duration of action, with nonanal comprising 40-70% and decanal comprising 10-30% of the total formulation weight

Inventive Principle:

Principle #35Parameter changes

2Reliability

If known mosquito control agents are used, then mosquito control is attempted, but efficacy is poor due to difficulties in ensuring adequate consumption by target organisms

Engineering Contradiction:

Improvecontrol efficacyVSAvoidagent consumption by mosquitoes

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent creates a synthetic chemical profile that copies and mimics the natural odor of chickens and other bird species, which are known mosquito attractants, thereby enhancing mosquito attraction and ensuring adequate consumption of control agents

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The formulation acts as an intermediary substance that bridges the gap between mosquito attraction and control agent delivery, using bird-derived chemical compounds as mediators to lure mosquitoes into contact with control agents

Inventive Principle:

Principle #24Intermediary (Mediator)
