Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous X-ray irradiation is used to capture internal structure, then measurement precision is improved, but temporal resolution deteriorates
Solution Approach 1:
The patent applies periodic action by using pulsed electromagnetic wave irradiation instead of continuous irradiation. The irradiation is performed in synchronized pulses that correspond to the periodic operation cycles of the specimen, allowing capture of internal structures at specific temporal moments while maintaining measurement precision through accumulated pulse data.
Solution Approach 2:
The timing control device performs preliminary action by pre-synchronizing the irradiation timing with the specimen operation timing. The system predicts and prepares the optimal irradiation moments based on the specimen's operational cycle, ensuring that pulses are delivered at the precise moments when internal structure evaluation is most effective.
2Loss of time
If high-speed pulsed irradiation is used to improve temporal resolution, then loss of time is reduced, but measurement precision deteriorates
Solution Approach 1:
The system employs feedback through the timing control device that monitors specimen operation timing and adjusts irradiation pulse timing accordingly. The detection results from previous pulses feed into the timing control to optimize subsequent pulse delivery, ensuring that even at high speeds, measurement precision is maintained through adaptive synchronization.
Solution Approach 2:
The patent maintains continuity of useful action by using a high repetition rate of pulsed irradiation that continuously samples the specimen's internal structure throughout its operational cycle. Although each pulse is brief, the continuous sequence of synchronized pulses ensures both high temporal resolution and accumulated measurement precision.
3Measurement precision
If synchronization with specimen operation is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The timing control device utilizes the specimen's own operational timing signals to drive the synchronization. Rather than requiring an external complex control system, the system leverages the specimen's inherent periodic operation to generate the reference timing, allowing the irradiation system to self-synchronize with minimal additional complexity.
Solution Approach 2:
The timing control device serves multiple functions: it generates irradiation timing signals, synchronizes with specimen operation, and adjusts pulse parameters. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing device complexity while achieving precise synchronization for improved measurement accuracy.
