Solution Overview

Problem

Existing mosquito control methods either repel mosquitoes or kill them, but do not effectively target mosquito eggs, which are a crucial stage in population control, and can lead to the development of insecticide-resistant mosquitoes.

Innovation Solution

An apparatus comprising a spawning tank, a water recycling tank with a confining chamber, and a water pump that filters and drowns mosquito eggs, allowing for efficient population control by targeting the unique characteristics of mosquito eggs, which are laid in groups and float on water.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If mosquito eradicating products such as malathion and pyrethroid sprays are used, then mosquito populations are reduced, but insecticide-resistant mosquitoes develop in long term applications

Engineering Contradiction:

Improvemosquito population reductionVSAvoidinsecticide resistance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent extracts and targets the specific vulnerable stage of mosquito eggs for eradication, separating this function from general mosquito control methods. By focusing specifically on egg rafts rather than adult mosquitoes or larvae, the system eliminates the harmful effect of insecticide resistance while maintaining population control effectiveness

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary action by eradicating mosquito eggs before they can develop into larvae and adult mosquitoes. This preventive approach stops the mosquito life cycle at its earliest stage, preventing the development of resistance that occurs with repeated adult mosquito exposure to insecticides

Inventive Principle:

Principle #10Preliminary action

2Productivity

If electric zappers and large fan box are used to kill mosquitoes, then mosquito populations are reduced, but a variety of other flying insects which play important roles in plants fertilization are also killed

Engineering Contradiction:

Improvemosquito population reductionVSAvoidcollateral damage to beneficial insects

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating a specialized environment within the spawning tank that is specifically attractive to mosquito eggs through water conditions and organic matter, while the fine mesh filter provides localized selective filtration. This targeted approach ensures only mosquito eggs are captured and eradicated, while beneficial insects are unaffected

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system introduces an intermediary spawning tank environment that selectively attracts mosquito eggs through specific water conditions and organic substrates. This intermediary stage allows for selective capture of mosquito eggs via the fine mesh filter without directly exposing beneficial insects to harmful eradication mechanisms

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If traditional three-step trapping devices are used, then mosquitoes are trapped and drowned, but the process is complex and requires multiple components

Engineering Contradiction:

Improvemosquito trapping efficiencyVSAvoidtrapping device structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the attraction, trapping, and eradication functions into a single integrated spawning tank system. The tank combines water retention, organic matter accumulation, and fine mesh filtration in one structure, eliminating the need for separate funnel, collection chamber, and killing mechanism required in traditional three-step devices

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The spawning tank serves multiple functions simultaneously: it attracts mosquito eggs through water and organic matter, traps them via the fine mesh filter, and eradicates them through drowning in the collected water. This multi-functional design simplifies the overall system while maintaining effective mosquito control

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An apparatus for controlling mosquito populations by eradicating mosquito eggs. The apparatus consists of a spawning tank, a multi-purpose spawning tank cover, a confining chamber, a water refilling chamber and a water pump. The apparatus can be set to operate either in automated mode or in manual mode. In the automated operation mode, a timer-controlled water pump transfers mosquito eggs from the spawning tank to the confining chamber where the mosquito eggs are trapped and drowned. In the manual operation mode, the cover of the spawning tank is used as a depressor bowl and the spawning tank functions as a confining chamber. Experimental results show that the mosquito egg eradicating apparatus can effectively eradicate 90% of field mosquito eggs in four hours.
