Solution Overview

Problem

Current methods for controlling mosquito populations, such as biological insecticides and chemical attractants, face environmental concerns and resistance issues, necessitating the development of more effective and sustainable methods to attract and trap gravid mosquitoes.

Innovation Solution

A composition comprising nitrogen, phosphorus, and potassium (N-P-K) additives combined with specific attractants like semiochemicals, pheromones, and natural substances like whey, tailored to attract specific mosquito species to oviposition sites, such as mosquito traps or artificial breeding pools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biological insecticides and chemical attractants are used to control mosquito populations, then mosquito control effectiveness is improved, but environmental harm and mosquito resistance increase

Engineering Contradiction:

Improvemosquito control effectivenessVSAvoidenvironmental harm

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses an artificial breeding pool as an intermediary structure to redirect mosquito oviposition behavior. Instead of directly killing mosquitoes with insecticides, the system provides an alternative water body with attractants that draws mosquitoes away from natural breeding sites. This mediator approach reduces direct chemical intervention while maintaining control effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the chemical parameters of the artificial breeding pool water by adding specific attractants (ammonium acetate, putrescine, cadaverine) to change its attractiveness to mosquitoes. This parameter change makes the artificial pool more appealing than natural bodies of water, redirecting oviposition behavior without requiring broad-spectrum insecticides.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If broad-spectrum insecticides are used to control mosquito populations, then overall mosquito reduction is improved, but mosquito resistance to these measures develops over time

Engineering Contradiction:

Improvemosquito population reductionVSAvoidsustainability of control measures

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies species-specific attractants tailored to target particular mosquito species rather than using broad-spectrum insecticides that affect all mosquitoes. This localized approach targets specific pest populations while preserving beneficial insect species, reducing the selective pressure that leads to resistance development.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent replaces the mechanical/chemical killing mechanism of insecticides with a behavioral manipulation mechanism using chemical attractants. Instead of directly killing mosquitoes through toxic exposure, the system uses chemical signals to guide oviposition behavior toward controlled artificial pools where eggs can be monitored and treated more precisely.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If standing water is used to naturally attract mosquitoes for oviposition, then attraction effectiveness is improved, but specificity to target species is reduced

Engineering Contradiction:

Improveattraction effectivenessVSAvoidspecies specificity

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent changes the chemical composition parameters of the artificial breeding pool water by adding specific ratios of attractants (ammonium acetate, putrescine, cadaverine) that mimic the chemical signature preferred by target mosquito species. This parameter adjustment creates a chemically distinct environment that selectively attracts specific species while repelling or not attracting others.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a locally optimized chemical environment in the artificial breeding pool that differs from natural water bodies. By controlling the concentration and combination of attractants in this specific location, the system can tailor the chemical profile to match the preferences of target species, achieving species-specific attraction that natural standing water cannot provide.

Inventive Principle:

Principle #3Local quality
