Insect Trap Air Duct and Screening Mesh for Mosquito Attraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect traps face challenges in effectively luring and trapping flying insects like mosquitoes due to inadequate dispersion of insect attractants and turbulence issues, leading to suboptimal capture performance.
Innovation Solution
The insect trap incorporates a base container with an insect attractant and moisture-retaining material, a container canopy with an air duct and air-permeable screening mesh, and a suction member to optimize the dispersion of odorized air and vapors, mimicking human presence for attraction, with a blocking ratio between 0.2 and 5 to enhance capture efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing insect traps use conventional attractant dispersion methods, then the structure is simple, but the dispersion is inadequate and turbulence occurs leading to suboptimal capture performance
Solution Approach 1:
The trap is divided into functionally independent modules: a base container for attractant storage, a container canopy for air flow control, an air duct part for directed air movement, and a screening mesh for turbulence reduction. This segmentation allows each component to be optimized for its specific function, improving overall capture performance while maintaining manufacturing simplicity through modular assembly.
Solution Approach 2:
The air duct part acts as an intermediary component that mediates between the attractant source and the external environment. It directs and conditions the air flow carrying attractant vapors, optimizing their dispersion pattern to enhance insect attraction while the screening mesh mediates turbulence to maintain laminar flow conditions.
2Productivity
If the screening mesh has high air permeability to expel odorised air, then insect attraction is enhanced, but turbulence increases reducing capture efficiency
Solution Approach 1:
The screening mesh parameters (aperture size, strand thickness, blocking ratio between 0.2 and 5) are precisely optimized to achieve the desired balance. By adjusting these parameters, the mesh allows sufficient air permeability for effective attractant dispersion while simultaneously reducing turbulence to maintain stable laminar flow conditions for optimal capture efficiency.
3Stability of the object's composition
If the screening mesh blocking ratio is increased to reduce turbulence, then air flow stability improves, but air permeability decreases reducing attractant dispersion
Solution Approach 1:
The blocking ratio parameter is precisely tuned within the range of 0.2 to 5 to achieve optimal performance. This parameter optimization ensures that the screening mesh provides sufficient turbulence reduction for stable air flow while maintaining adequate air permeability for effective dispersal of attractant vapors throughout the surrounding environment.

Function Achieved in This Case
This design significantly improves capture performance by optimizing air permeability and mimicking human presence, resulting in higher attraction and trapping rates of mosquitoes, as demonstrated by experimental data showing peak performance within a specific range of air blockage.
Implementation Method 1
the canopy surface part comprises an air permeable screening mesh... the blocking ratio defined as the thread thickness over the aperture area lies between 0.2 and 5... allows for optimized air permeability of the screening mesh to expel odorised air or vapour from the insect trap
Implementation Method 2
a suction member configured for drawing air into the intake end and expelling the air through the exhaust end into the base container... An air flow prevails through the suction duct, which air flow applies a negative pressure or a suction current to the suction opening
Implementation Method 3
a base container arranged for storing an insect attractant and a moisture retaining material... expel odorised air or vapour from the insect trap... mimicking human presence in optimized manner for attracting insects
