Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cable connection is used between radiation device and radiography device, then synchronization accuracy is improved, but device mobility and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The radiography device uses a wireless communication unit to receive timing signals from the radiation device without physical cable connection, thereby maintaining synchronization accuracy while improving device mobility and ease of operation.
2Ease of operation
If each device generates its own clock independently, then device independence and ease of operation are improved, but synchronization stability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the radiography device receives timing signals from the radiation device and adjusts its own clock operation accordingly. The controller modifies the clock frequency based on the received timing information, ensuring synchronization stability while maintaining device independence through wireless communication.

AI summary
A radiography device includes an interface unit and a controller. The interface unit connects to an external interface. The controller operates according to timing signals from the external interface connected to the interface unit so as to synchronize with timing of repetition of generation of radiation by a radiation device that generates radiation in serial radiography in which frame images are generated. Even after connection between the interface unit and the external interface is cut off, the controller repeats operation for generating a frame image while synchronizing with the radiation device without communicating with an outside.
