Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication methods for mobile radiographic imaging apparatuses fail to maintain stable connections during dynamic imaging due to frequent disconnections caused by movement, leading to delays and retransmissions of dynamic images.
Innovation Solution
A mobile radiographic imaging apparatus with a detector and wireless communication interface that detects multiple access points, connects to a first access point during dynamic imaging, and inhibits changing the connection until image output is complete, using a hardware processor to control the change of access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mobile radiographic imaging apparatus moves to utilize another wireless access point with stronger signal during dynamic imaging, then wireless communication strength is improved, but disconnection and retransmission occur causing delay in image output
Solution Approach 1:
The system performs preliminary assessment of wireless communication strength before initiating dynamic imaging. It selects and connects to an appropriate access point in advance, and maintains connection to that access point throughout the imaging process even if other access points become available, thereby preventing disconnection and retransmission delays
Solution Approach 2:
The system dynamically adjusts its wireless connection strategy based on imaging state. During dynamic imaging, it locks onto a selected access point and maintains that connection statically despite dynamic availability of other access points, creating a controlled static connection within a dynamic environment to prevent communication disruptions
2Adaptability or versatility
If the mobile radiographic imaging apparatus switches wireless access points during dynamic imaging, then adaptability to environment is improved, but connection stability deteriorates causing disconnection
Solution Approach 1:
The system performs preliminary evaluation of available access points before dynamic imaging and selects the most suitable one. It then commits to that selection for the duration of the imaging process, avoiding mid-process switching that would compromise connection stability
Solution Approach 2:
Instead of dynamically switching access points based on real-time signal strength fluctuations (conventional approach), the system inverts the strategy by selecting an access point before imaging and maintaining connection to it throughout, prioritizing connection stability over optimal signal strength adaptation
3Reliability
If the mobile radiographic imaging apparatus maintains connection to initial access point during dynamic imaging, then connection stability is improved, but inability to utilize stronger signal reduces communication efficiency
Solution Approach 1:
The system performs preliminary optimization by selecting the most suitable access point before dynamic imaging begins. This pre-selection ensures both stable connection and adequate communication efficiency for the duration of the imaging process
Solution Approach 2:
The system changes the parameter of access point selection timing from real-time dynamic selection to pre-imaging selection. This parameter change optimizes the balance between connection stability and communication efficiency by making the selection before the imaging process begins

AI summary
A mobile radiographic imaging apparatus that performs dynamic imaging by using radiation, includes a detector, a wireless communication interface, and a hardware processor. The detector detects a first wireless access point and a second wireless access point. The wireless communication interface connects to the first wireless access point as a connection point and outputs a dynamic image including a plurality of frames acquired in the dynamic imaging to the first wireless access point. The hardware processor controls a change of the connection point from the first wireless access point to the second wireless access point. The hardware processor further performs control to inhibit the change of the connection point in a period when the frame images are still being output to the first wireless access point.
