Engineering Contradiction Analysis
1Productivity
If multiple print jobs are allocated to one roll of rolled paper, then the productivity is improved, but the measurement precision of print job execution time deteriorates
Solution Approach 1:
The system dynamically adjusts the estimated execution time of each print job based on real-time changes in the combination of allocated print jobs. The processor continuously updates the estimation by considering the transport speed determined by the minimum rasterization speed among all jobs on the same roll, enabling accurate time prediction despite changing job combinations.
Solution Approach 2:
The system implements feedback by continuously monitoring the actual combination of print jobs allocated to each roll and comparing it with the estimated execution time. The processor updates the estimation based on the determined transport speed, creating a closed-loop system that improves measurement precision while maintaining high productivity.
2Manufacturing precision
If the transport speed is kept constant for multiple print jobs, then the image quality is maintained, but the time needed to execute print jobs increases
Solution Approach 1:
The system changes the parameter of transport speed dynamically based on the combination of print jobs allocated to each roll. The transport speed is determined by the minimum rasterization speed among all jobs on the same roll, allowing the system to optimize execution time while maintaining image quality through controlled speed variations.
Solution Approach 2:
The system makes the transport speed dynamic rather than fixed, adjusting it according to the specific combination of print jobs. This allows the system to minimize total execution time by selecting optimal speeds for each job combination while still maintaining quality standards through controlled speed changes.
3Loss of time
If the transport speed is adjusted according to print job combinations, then the time needed to execute print jobs is reduced, but the image quality may be degraded
Solution Approach 1:
The system changes the transport speed parameter dynamically based on the combination of print jobs, using the minimum rasterization speed among all jobs on the same roll as the determining factor. This ensures that speed adjustments are made in a controlled manner that balances time reduction with image quality maintenance.
Solution Approach 2:
The system replaces rigid mechanical speed control with a flexible software-based estimation and control mechanism. The processor calculates and adjusts transport speeds based on computational analysis of job combinations, allowing more precise and adaptable speed control that balances time and quality requirements.
