Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual sheet tracking is implemented throughout the production process, then sheet loss can be identified immediately, but the amount of data to process becomes considerable and management becomes cumbersome
Solution Approach 1:
The patent segments the production control into two levels: load-level tracking (macro) and sheet-level tracking (micro). The system first tracks production loads as groups through load identifiers, and only tracks individual sheets when necessary for high-value or high-risk items. This segmentation reduces overall data processing complexity while maintaining reliability for critical cases.
Solution Approach 2:
The system implements selective tracking where not all sheets require individual tracking throughout the entire process. Instead, tracking intensity is adjusted based on the specific production context, security requirements, and risk assessment. This partial action approach reduces data processing burden while maintaining adequate control.
2Adaptability or versatility
If complex production tasks with multiple distinct production jobs are executed in a same printing plant, then production flexibility is improved, but coordination and control become more difficult
Solution Approach 1:
The patent implements a universal production control system that can handle multiple production jobs, load types, and security requirements through a single integrated platform. The system uses standardized data structures and control procedures that can be applied across different production contexts, enabling the printing plant to execute diverse production tasks without requiring separate control systems for each job type.
Solution Approach 2:
The system introduces an intermediary production control layer that coordinates between different production jobs and processing stations. This intermediary layer manages the complexity of multiple simultaneous production tasks by orchestrating resource allocation, scheduling, and coordination, thereby simplifying the overall control architecture while maintaining production flexibility.
3Reliability
If real-time monitoring of all production parameters is implemented, then production control is improved, but system complexity and processing requirements increase
Solution Approach 1:
The patent implements differential monitoring where the level of real-time monitoring is adjusted based on local requirements. Critical parameters and high-risk production stages receive intensive real-time monitoring, while less critical parameters use periodic or event-driven monitoring. This local quality approach optimizes the balance between control reliability and system complexity.
