Solution Overview
Problem
Existing flying pest traps using LED light sources face challenges in managing heat generation effectively, leading to reduced LED lifetime and increased maintenance costs due to the need for frequent servicing.
Innovation Solution
A detachable attracting element with LEDs mounted on a support section, coupled to a receiving section with higher thermal conductivity, utilizing a spring clip for secure attachment and a heat dispersing surface to transfer heat efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED light sources are used to replace fluorescent UV tubes, then power consumption is reduced and lifetime is extended, but heat generation increases which reduces LED lifetime and increases maintenance frequency
Solution Approach 1:
The patent extracts the heat sink function from the attracting element assembly and places it in the housing. The attracting element with LEDs can be replaced independently without removing the heat sink, resolving the contradiction by separating the heat management function from the consumable component.
Solution Approach 2:
The patent introduces a thermal interface material (TIM) as an intermediary between the attracting element and the heat sink in the housing. This TIM facilitates efficient heat transfer from the LEDs to the heat sink, managing the heat generation issue while maintaining the energy efficiency benefits of LED technology.
2Temperature
If heat sink is permanently attached to attracting element, then heat management is effective, but replacement cost increases significantly when attracting element reaches end of life
Solution Approach 1:
The patent segments the trap system into replaceable attracting elements and a permanent housing containing the heat sink. This segmentation allows the attracting element to be replaced independently every 2-3 years while the heat sink remains in place, dramatically reducing replacement costs while maintaining effective heat management through the thermal interface material.
3Ease of repair
If attracting element is made detachable for easy replacement, then maintenance cost is reduced, but heat transfer efficiency may be compromised
Solution Approach 1:
The thermal interface material serves as a mediator that maintains reliable thermal contact between the detachable attracting element and the permanent heat sink. This intermediary ensures that even with the detachable design allowing easy replacement, the heat transfer efficiency remains high through proper thermal coupling.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances heat dissipation, prolongs LED life, reduces maintenance frequency, and lowers replacement costs by allowing separate replacement of the attracting element without replacing the heat sink.
Implementation Method 1
The receiving section has higher thermal conductivity than the support section, so as to transfer heat generated by the LEDs of the attracting element to the receiving section
