Segmented Cleaning Device for LCD Panel Energy Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cleaning devices for liquid crystal display panels waste energy due to being fully activated for all sizes of panels, even though smaller panels leave unused regions inactive, leading to inefficient energy use.
Innovation Solution
Divide the cleaning device into at least two regions to control the cleaning mode based on the detected width and position of the panel, allowing only the necessary regions to be turned on for cleaning, thereby optimizing energy usage without modifying the hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning device is completely turned on for cleaning, then all regions can clean the panel, but energy is wasted when smaller panels are cleaned
Solution Approach 1:
The cleaning device is divided into multiple independent control regions (first cleaning region, second cleaning region, third cleaning region) along the conveying direction. Each region can be independently controlled to turn on or off based on the panel width, allowing only the necessary regions to operate and thus reducing energy consumption while maintaining effective cleaning coverage.
Solution Approach 2:
The cleaning device implements dynamic control where the activation of different cleaning regions is adjusted in real-time based on the detected panel width. The control structure dynamically determines which regions to activate, making the system adaptable to different panel sizes and avoiding unnecessary energy consumption from static full-device operation.
2Use of energy by moving object
If the cleaning device is divided into multiple regions with independent control, then energy can be saved, but device complexity increases
Solution Approach 1:
The cleaning device is divided into multiple independent control regions (first cleaning region, second cleaning region, third cleaning region) along the conveying direction. Each region can be independently controlled to turn on or off based on the panel width, allowing only the necessary regions to operate and thus reducing energy consumption while maintaining effective cleaning coverage.
Solution Approach 2:
The detection structure detects the panel width and provides feedback to the control structure, which then determines the appropriate cleaning regions to activate. This feedback mechanism enables automatic adaptation to different panel sizes without requiring complex manual configuration, simplifying the overall control while achieving energy savings.
