Insect Trap With Segmented Suction Fans And UV LED
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insect traps using UV LEDs for attracting and suctioning insects face issues such as noise from fouled suction fans, escape of mosquitoes, and low suction efficiency due to uncontrollable air stream velocity and power consumption.
Innovation Solution
The insect trap design includes a UV LED module with controlled wavelength and intensity for safe human exposure, a suction fan with adjustable rotational speed and diameter to minimize noise, and specific air stream velocity control through the insect filter and collector geometry to enhance suction efficiency.
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 suction fan
Solution Approach 1:
The suction system is divided into two separate components: a first suction fan for attracting insects and a second suction fan for collecting insects. This segmentation prevents the collection fan from being fouled by insects, thereby reducing noise while maintaining collection efficiency
Solution Approach 2:
A suction channel is introduced as an intermediary structure between the attraction zone and collection zone. The channel guides insects from the first suction fan area to the second suction fan area, preventing direct contact between insects and the collection fan blades
2Productivity
If the suction fan speed is increased to improve insect suction, then suction efficiency is improved, but noise and power consumption increase
Solution Approach 1:
The suction function is segmented into attraction (first fan) and collection (second fan), allowing each fan to operate at optimized speeds. The collection fan can run at lower speeds since it only needs to handle already-attracted insects, reducing noise and power consumption
Solution Approach 2:
The system changes operational parameters by using two fans with different rotational speeds. The first fan operates at higher speed for effective attraction, while the second fan operates at lower speed for quiet collection, optimizing the balance between efficiency and noise
3Productivity
If a typical UV lamp is used for attracting insects, then attraction effectiveness is improved, but power consumption and heat generation increase
Solution Approach 1:
The traditional UV lamp (thermal/electromagnetic system) is replaced with a UV LED module (solid-state electroluminescence system). This substitution maintains insect attraction effectiveness while significantly reducing power consumption and heat generation
Solution Approach 2:
The light source parameters are changed from conventional UV lamp characteristics (high power, high temperature) to UV LED characteristics (low power, low temperature). The LED module emits UV light at wavelengths effective for insect attraction but with much lower energy consumption and minimal heat output

AI summary
Exemplary embodiments provide an insect trap adapted to attract and collect insects using UV light. The insect trap includes: a main body; an insect filter disposed on the main body and allowing insects to pass therethrough; a motor disposed below the insect filter; a suction fan disposed under the motor and rotated by the motor; a plate-shaped UV LED installation unit disposed above the insect filter and provided with a UV LED module; a buttress supporting the UV LED installation unit above the main body while separating the UV LED installation unit above the main body so as to allow insects to be suctioned into a space between the main body and the UV LED installation unit; and an insect collector disposed under the main body and collecting insects.
