In Situ CO2 Insect Trap with Lactic Acid Gel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling mosquito populations, such as chemical pesticides and natural predators, are ineffective and pose health and environmental risks, while existing trapping devices fail to attract mosquitoes effectively due to unsteady attractant release and toxicity concerns.
Innovation Solution
A flying insect trapping device that produces CO2 in situ, combined with a biochemical lure system using L(+)-lactic acid and a UV-curable aqueous solution forming a gelling network, providing a steady and uniform release of attractants, reducing toxicity and increasing the device's effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemical pesticides are used to control mosquito populations, then mosquito population reduction is achieved, but health and environmental risks increase
Solution Approach 1:
The patent converts the harmful effect of mosquito bites and disease transmission into a beneficial control mechanism by using mosquito-attracting substances (CO2, lactic acid, octenol) to lure mosquitoes into traps where they are harmlessly contained, transforming the problem of mosquito attraction into a solution for population control without chemical pesticides
Solution Approach 2:
The patent introduces intermediary substances (CO2, lactic acid, octenol) that mediate between the trap and mosquitoes, using these chemical mediators to attract mosquitoes to the trap without requiring direct contact with toxic substances, thus controlling mosquitoes while avoiding health and environmental risks
2Productivity
If existing trapping devices use attractants, then mosquito attraction is achieved, but attractant release is unsteady and toxicity concerns arise
Solution Approach 1:
The patent changes the physical and chemical parameters of attractant release by using multiple attractant substances (CO2, lactic acid, octenol) with different release characteristics, and controlling their release rates and concentrations to achieve steady and reliable mosquito attraction throughout the device's operational life
Solution Approach 2:
The patent employs a composite attractant system combining multiple substances (CO2 gas, lactic acid liquid, octenol liquid) with different properties and release mechanisms, creating a synergistic effect that maintains steady attraction reliability longer than any single attractant could achieve alone
