Solution Overview
Problem
Current methods for collecting operation states in printing factories, especially preprocessing operations, are inefficient and prone to overlooking or false detection due to the need for manual input and the high processing time required for video analysis across multiple devices, leading to inaccurate productivity management.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video analysis is performed on all device areas to collect operation state information, then completeness of data collection is improved, but processing time increases significantly
Solution Approach 1:
The patent segments the video analysis process by dividing the factory floor into multiple monitoring areas, each assigned to a specific camera. The control unit manages these segmented areas and selectively analyzes videos based on device status, rather than processing all areas uniformly. This segmentation allows targeted analysis of only relevant areas, reducing overall processing time while maintaining data completeness for active devices.
Solution Approach 2:
The patent implements dynamic monitoring by switching monitoring targets based on real-time device status. The control unit determines which devices are currently operating and directs video analysis resources accordingly. This dynamic approach ensures that video analysis is performed only on areas where devices are actually in use, optimizing the balance between data collection completeness and processing efficiency.
2Reliability
If all videos are analyzed to ensure comprehensive monitoring, then monitoring coverage is improved, but false detection increases due to analyzing unused devices
Solution Approach 1:
The patent applies preliminary action by having the control unit determine device status and identify monitoring targets before initiating video analysis. The system pre-determines which devices are currently operating based on status information and directs camera monitoring accordingly. This preliminary filtering prevents the system from analyzing videos of unused devices, thereby eliminating false detections while maintaining comprehensive monitoring of active devices.
Solution Approach 2:
The patent implements feedback mechanisms where the control unit continuously monitors device status and adjusts video analysis targets accordingly. When device status changes, the system receives feedback and reconfigures monitoring targets to reflect current operational state. This feedback loop ensures that video analysis is always directed at relevant areas, preventing false detections while maintaining accurate monitoring coverage.
3Device complexity
If manual input method is used for preprocessing operation information, then device complexity is reduced, but accuracy and reliability of recorded times deteriorate
Solution Approach 1:
The patent applies self-service by enabling the system to automatically monitor and record operation timing information without requiring manual worker input. The camera system captures images and the control unit automatically determines operation start and end times based on detected device status changes. This automated self-monitoring eliminates the inaccuracies and timing delays associated with manual worker reporting, while the modular camera and control unit architecture keeps device complexity manageable.
