Innovation Solution
A radiographic imaging device equipped with a generating unit for image data and a communicating unit that can switch between direct and indirect wireless communication modes, allowing it to adapt communication based on settings and conditions, ensuring reliable data transfer even in poor communication states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used to connect the electronic cassette and console, then communication reliability is improved, but portability and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The electronic cassette and console are equipped with wireless communication units that enable data transmission without physical cables, thereby maintaining communication reliability while significantly improving portability and ease of operation.
2Ease of operation
If indirect wireless communication via base station is used, then ease of operation is improved, but reliability deteriorates in environments with poor wireless coverage
Solution Approach 1:
The patent implements dynamic communication mode switching capability. The system can automatically or manually switch between indirect wireless communication (via base station) and direct wireless communication (peer-to-peer) based on the operational environment and signal conditions, thereby maintaining ease of operation while ensuring communication reliability in various settings.
Solution Approach 2:
The patent changes the communication parameter from fixed indirect wireless mode to variable mode that can switch between indirect and direct communication. This parameter change allows the system to adapt to different environmental conditions, maintaining reliability in areas with poor wireless coverage by switching to direct communication mode.
3Reliability
If direct wireless communication is used, then reliability in poor coverage areas is improved, but ease of operation deteriorates due to connection management complexity
Solution Approach 1:
The patent implements automatic connection management functionality where the electronic cassette and console autonomously establish and maintain wireless connections. The system automatically detects available communication modes, initiates connection protocols, and manages data transmission without requiring manual intervention from the operator, thereby maintaining reliability in poor coverage areas while preserving ease of operation.

AI summary
A radiographic imaging device has: a generating unit that generates image data expressing a radiographic image formed by irradiated radiation; a first communicating unit at which wireless communication is possible selectively in either of a direct communication mode or an indirect communication mode; a storing unit that stores a setting of a communication mode; and a control unit that, if a setting to carry out communication in the direct communication mode has been made, controls the first communicating unit to carry out wireless communication in the direct communication mode, and, if a setting to carry out communication in the indirect communication mode has been made, controls the first communicating unit to attempt wireless communication in the indirect communication mode with a control device that controls the radiographic imaging device, and, if communication is impossible, controls the first communicating unit to carry out wireless communication in the direct communication mode.
