Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple attractant features (odors, scents, sounds, lights, temperatures, humidity) are used to achieve good mosquito trapping effects, then the trapping effectiveness is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts and isolates the carbon dioxide generation function from the complex multi-attractant system. By focusing solely on CO2 as the attractant and using a simple water-acid reaction mechanism, the device eliminates the need for multiple attractant features while maintaining trapping effectiveness. The net cover assembly with air inlet/outlet parts and fan creates a dedicated CO2 delivery system that replaces complex odor, sound, light, and temperature control mechanisms.
Solution Approach 2:
The fan serves multiple functions: it drives air flow through the net cover assembly to deliver CO2 to mosquitoes, and it creates suction to draw mosquitoes into the storage box. This multi-functionality replaces what would otherwise require separate mechanisms for attractant delivery and mosquito capture, simplifying the overall device structure while maintaining effectiveness.
2Reliability
If multiple mosquito trapping or exterminating facilities are used, then the mosquito extermination capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses the fan's air flow capability to serve dual purposes: delivering CO2 attractant to lure mosquitoes and creating suction to capture them in the storage box. By converting the fan's air moving capability into both attraction and capture functions, the device eliminates the need for separate trapping and exterminating facilities, reducing complexity while maintaining effectiveness.
3Reliability
If complex mosquito-lured lamps or mosquito-exterminating lamps are used, then the mosquito trapping and extermination effectiveness is improved, but the device complexity and cost remain high
Solution Approach 1:
The patent removes the lamp-based attractant and extermination mechanisms entirely, replacing them with a CO2-based biological attractant system. The water-acid reaction generates CO2 that is delivered through the net cover assembly, eliminating the need for complex electrical lamp systems while achieving effective mosquito attraction and capture.
4Device complexity
If a simple structure with only fan as electricity utilization component is used, then the device complexity and cost are reduced, but the mosquito trapping effectiveness may be compromised
Solution Approach 1:
The fan is designed to perform multiple critical functions: driving CO2 air flow through the net cover assembly to attract mosquitoes, and creating suction to draw mosquitoes into the storage box. This multi-functionality ensures that despite the simple structure with only one electrical component, the device maintains effective mosquito trapping capability through optimized air flow paths and net cover geometry.
Solution Approach 2:
The patent uses pneumatic principles to achieve mosquito attraction and capture. The fan creates pressure differentials that drive CO2 flow through the net cover assembly and create suction to draw mosquitoes into the storage box. By leveraging pneumatic effects, the simple fan-based system achieves complex trapping functionality without additional mechanical or electrical components.

Implementation Method 1
under the action of the fan, air enters the mosquito storage box from the air inlet part and is finally discharged from the air outlet part
Implementation Method 2
the carbon dioxide mosquito luring part is arranged to simulate human respiration, and only carbon dioxide gas is available for mosquito luring, and is diffused under the action of the air duct

AI summary
A carbon dioxide-lured mosquito trapping device includes a main body, as well as a net cover assembly, a fan, and a mosquito storage box that are sequentially arranged from top to bottom in a height direction of the main body. The net cover assembly is provided with an air inlet part and an air outlet part, and under the action of the fan, air enters the mosquito storage box from the air inlet part and is finally discharged from the air outlet part. A carbon dioxide mosquito luring part configured for generating carbon dioxide gas arranged on a side of the main body is further included. The carbon dioxide mosquito luring part includes a discharge hole formed in the net cover assembly for outputting carbon dioxide gas. Despite of a simple overall structure and a low cost, the device of a simple structure achieves mosquito luring and trapping functions.
