Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing excimer lamps used in UV/O3 cleaning methods face challenges in determining the end-of-life span due to temperature issues with IC tags, interference from high-frequency/high-voltage, and data transmission problems, especially when installed on metal cases with water-cooled blocks.
Innovation Solution
The solution involves installing an IC tag in an insulated holder within the high voltage power supply terminal, providing a gap between the power supply cable and the IC tag to prevent overheating and electromagnetic interference, and using a high-frequency current absorber and shield material to protect the IC tag from noise and electric fields, ensuring reliable data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an IC tag is installed on the excimer lamp to track life span, then data tracking capability is improved, but the IC tag malfunctions due to high temperature and electromagnetic interference
Solution Approach 1:
The system separates the IC tag from the excimer lamp body by installing it on the power supply terminal instead. This segmentation isolates the IC tag from the high-temperature and high-electromagnetic-field environment of the lamp, while still enabling life span tracking through periodic communication between the IC tag and control unit.
Solution Approach 2:
The power supply terminal acts as an intermediary carrier for the IC tag, providing a location that is electrically connected to the lamp circuit but physically separated from the arc tube. This intermediary position allows the IC tag to access power and communication lines without being exposed to the harsh conditions at the lamp discharge zone.
2Ease of operation
If the IC tag is placed near the high voltage power supply cable, then data communication is facilitated, but electromagnetic interference and overheating occur
Solution Approach 1:
The insulated holder provides a localized environment with different electromagnetic and thermal properties than the surrounding space. By placing the IC tag within this specially designed holder made of insulating material, the tag receives protected conditions (reduced EMI and heat) while remaining in close proximity to the power supply cable for communication purposes.
3Temperature
If the IC tag is installed on the metal case with water-cooled block, then heat dissipation is improved, but data transmission is blocked by metal interference
Solution Approach 1:
The insulated holder serves as an intermediary structure between the metal case and the IC tag. It allows the IC tag to be positioned near the heat-dissipating metal case while the insulating material blocks electromagnetic interference from both the metal case and the power supply cable, maintaining data transmission capability.
4Object-affected harmful factors
If the gap between power supply cable and IC tag is increased, then electromagnetic interference is reduced, but insulation requirements are relaxed
Solution Approach 1:
The insulated holder changes the insulating parameters of the system by providing a structured insulating barrier between the power supply cable and IC tag. This allows for optimized spacing and insulation thickness, achieving adequate EMI protection without excessive gap distances that would complicate the overall device structure.
