Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operation completion is determined only at the end of work, then the system structure remains simple, but work progress cannot be monitored during operation and recovery is delayed
Solution Approach 1:
The patent implements feedback by continuously acquiring sensor data during work execution and comparing it against pre-stored normal progress sensor data. The progress information output unit generates feedback signals indicating whether work is progressing normally, enabling real-time monitoring without complex additional hardware. This resolves the contradiction by using information feedback from existing sensors to improve reliability while maintaining relatively simple system structure.
Solution Approach 2:
The patent introduces progress information as an intermediary element that mediates between sensor data and control decisions. The progress information output unit acts as an intermediary that processes sensor data and generates interpretable progress status, enabling work progress determination without directly complicating the control system architecture. This intermediary layer improves reliability while keeping the overall system structure manageable.
2Productivity
If real-time progress monitoring is implemented, then work progress can be determined during operation, but the control system becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-storing normal progress sensor data before work execution begins. This pre-stored data serves as a reference for real-time comparison during work progression, enabling quick productivity assessment without complex real-time analysis systems. The preliminary preparation of reference data allows real-time monitoring to be implemented with minimal additional computational complexity.
Solution Approach 2:
Real-time feedback is generated by continuously comparing current sensor data with pre-stored normal progress data. This feedback mechanism enables immediate detection of work progress status and abnormalities, allowing for timely recovery operations that improve productivity. The feedback approach achieves real-time monitoring capability while maintaining relatively simple system complexity by using straightforward data comparison.
3Reliability
If operation commands are generated based on real-time sensor data, then work can be corrected during execution, but the management unit requires more processing capability
Solution Approach 1:
The management unit performs preliminary preparation by storing normal progress sensor data and operation commands in advance. During work execution, the unit only needs to retrieve pre-stored commands and compare sensor data against pre-established patterns, rather than performing complex real-time decision-making. This preliminary preparation approach improves work execution accuracy while minimizing the processing power requirements during actual operation.
Solution Approach 2:
The system uses copying by storing reference copies of normal progress sensor data and corresponding operation commands in advance. During work execution, these pre-copied reference data and commands are retrieved and compared with actual sensor readings, enabling accurate work correction without requiring the management unit to perform complex real-time analysis. This copying approach improves reliability while keeping processing requirements manageable.
