Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insect traps using UV LEDs face issues such as noise from fouled suction fans, mosquito escape, insufficient suction efficiency, and high power consumption due to difficulties in controlling airflow velocity and fan speed.
Innovation Solution
An eco-friendly insect trap design featuring a UV LED module emitting light in the 340-390 nm range, a suction fan with controlled airflow velocity between 0.5-2.5 m/s, and a conical air collector to enhance mosquito attraction and suction efficiency while minimizing noise and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a suction fan is used to collect insects, then insect collection efficiency is improved, but noise is generated due to fouling of dead insects on the fan
Solution Approach 1:
The insect collection system is segmented into two separate functions: the suction fan handles air flow generation while the mesh structure handles insect collection. This separation prevents insects from directly contacting the fan blades, eliminating fouling and noise while maintaining collection efficiency through the mesh structure.
Solution Approach 2:
A mesh structure is introduced as an intermediary element between the suction fan and the external environment. The mesh allows air to pass through while intercepting insects, serving as a barrier that prevents insect-fan contact and eliminates the harmful fouling effect without compromising the suction function.
2Productivity
If suction fan speed is increased to improve insect suction, then suction efficiency is improved, but power consumption increases and mosquitoes may escape
Solution Approach 1:
The system dynamically balances suction fan speed with mesh structure parameters to achieve optimal performance. By adjusting fan speed within a specific range and coordinating with mesh aperture size, the system maintains sufficient suction efficiency while minimizing power consumption and preventing mosquito escape, avoiding the need for excessively high speeds.
Solution Approach 2:
The invention optimizes multiple parameters simultaneously: suction fan speed, mesh aperture size, and mesh density. By changing these parameters in combination rather than relying solely on high fan speed, the system achieves effective insect collection with reduced power consumption and minimized mosquito escape.
3Illumination intensity
If a typical UV LED is used to attract insects, then insect attraction is achieved, but control of airflow velocity and fan speed is difficult
Solution Approach 1:
The system optimizes the UV LED wavelength parameter to specifically attract mosquitoes while coordinating with controlled airflow velocity and fan speed parameters. This multi-parameter optimization approach simplifies overall control by establishing specific operating ranges for each parameter rather than requiring complex adaptive control systems.
