Insect Trap UV LED Suction Fan Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insect traps using UV LEDs for attracting and suctioning insects face issues such as noise from the suction fan due to fouling, escape of mosquitoes, and low suction efficiency due to difficulty in controlling the air stream velocity, along with high power consumption and environmental concerns from typical UV light sources.
Innovation Solution
An insect trap design featuring a UV LED module with controlled light wavelengths and intensity, a suction fan with adjustable rotational speed and fan blades, and a structured air collector to optimize air stream velocity and reduce noise, while using a buttress to separate the UV LED unit and main body for efficient insect suction.
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 patent introduces a protective cage structure that segments the space around the suction fan, creating a barrier between the fan blades and flying insects. This segmentation prevents insects from directly contacting the fan, reducing fouling and subsequent noise generation while maintaining the fan's insect collection function.
Solution Approach 2:
The protective cage acts as an intermediary element between the suction fan and insects. It allows the fan to continue its suction function while preventing direct interaction between insects and fan blades, thereby eliminating the noise problem caused by insect accumulation on the fan surface.
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 protective cage is installed beforehand to prevent insects from reaching the fan blades. This preliminary protective action eliminates the need for high fan speeds to compensate for fouling, allowing the fan to operate at lower, more efficient speeds with reduced noise and power consumption.
Solution Approach 2:
The system provides visual feedback through the transparent cage structure, allowing users to monitor insect collection progress. This feedback mechanism enables optimized fan operation by adjusting speed based on actual collection needs rather than maintaining constantly high speeds.
3Use of energy by stationary object
If a UV LED module is used for attracting insects, then power consumption is reduced and eco-friendliness is improved, but light intensity and attraction efficiency may be insufficient
Solution Approach 1:
The patent combines multiple UV LED modules in an array configuration, merging their individual light outputs to achieve sufficient overall attraction intensity. This merging approach maintains the low power consumption and eco-friendly benefits of LEDs while collectively producing adequate light for effective insect attraction.
Solution Approach 2:
The UV LED modules are arranged in a three-dimensional spatial configuration around the trap, extending the light emission in multiple directions and dimensions. This dimensional arrangement maximizes the effective attraction area and intensity without requiring individual LEDs to operate at higher power levels.
4Productivity
If the insect trap structure is made more complex to improve suction control, then suction efficiency is improved, but device complexity increases
Solution Approach 1:
The protective cage is designed with optimized opening sizes and patterns that dynamically control air flow and insect entry. The geometric configuration of the cage structure itself provides the suction control function, eliminating the need for additional complex mechanical control mechanisms while achieving precise suction regulation.
