Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If synchronized registration of auxiliary measured variables is implemented, then measurement precision is improved, but device complexity increases due to synchronization requirements
Solution Approach 1:
The patent combines multiple measuring transducers and their control circuits into integrated measurement units, where the control unit centrally manages synchronization for all transducers. This merging approach reduces overall system complexity while maintaining precise synchronization of auxiliary measured variable registration.
Solution Approach 2:
The control unit serves multiple functions: it controls the registration timing of all measuring transducers, processes the measured signals, and performs the difference calculation. This multi-functionality eliminates the need for separate synchronization devices, reducing system complexity while ensuring precise temporal coordination.
2Adaptability or versatility
If independent control signal sequences are used for each measuring transducer, then adaptability is improved, but synchronization difficulty increases
Solution Approach 1:
The control unit receives feedback signals from each measuring transducer indicating when measurement values are ready. Based on this feedback, the control unit independently adjusts the timing of control signals for each transducer, allowing flexible adaptation while maintaining synchronization through continuous temporal coordination.
Solution Approach 2:
The control signal sequences are designed to be dynamically adjustable in timing and frequency. The control unit can vary the registration timing of each transducer independently based on real-time conditions, enabling adaptability while maintaining synchronization through active temporal management.
