Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power supply voltage is monitored and compared with reference data to generate flag signals, then reliability of imaging operation is improved, but device complexity increases due to additional monitoring components
Solution Approach 1:
The voltage monitoring function is merged with the existing imaging device by integrating a data generator and flag generation section into the imaging unit. The data generator generates power supply voltage data that is then compared with reference data by the flag generation section, all within the imaging device architecture. This consolidation improves reliability without requiring entirely separate monitoring systems.
Solution Approach 2:
The patent introduces an intermediate data generator that converts power supply voltage into comparable data format, and a flag generation section that acts as a mediator between the voltage data and the imaging operation control. These intermediary components enable reliable voltage monitoring while maintaining modular integration within the imaging device.
2Measurement precision
If voltage monitoring and flag generation are implemented, then detection precision of power supply issues is improved, but loss of time for data processing increases
Solution Approach 1:
The system performs preliminary action by pre-establishing reference data for power supply voltage before actual imaging operations. The data generator is configured to generate power supply voltage data that can be immediately compared with pre-stored reference data, enabling rapid detection without extensive real-time processing delays.
Solution Approach 2:
The patent uses copying by creating a digital representation (data) of the power supply voltage that can be stored and compared against reference copies. This allows precise comparison of voltage conditions without requiring continuous complex analog analysis, reducing processing time while maintaining detection precision.
