Mobile X-Ray Console Shutdown Logic for Dual Battery Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile radiographic imaging apparatuses with dual power supply configurations, there is a risk of data corruption or battery deterioration due to user forgetfulness in turning off power supplies, and frequent inquiries for state checks can deplete the limited power supply.
Innovation Solution
A mobile radiographic imaging apparatus with two independent power supply units and control devices, where one control device inquires about the state of the other when a predetermined condition is satisfied, and adjusts shutdown or cancellation of shutdown based on the response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the DR console periodically inquires about the apparatus state to determine shutdown timing, then automatic power management is improved, but power consumption increases and battery may run out during actual rounds
Solution Approach 1:
The system implements periodic inquiry at predetermined intervals to balance automation with power conservation. The control device inquires about apparatus state at scheduled times rather than continuously, reducing power consumption while maintaining adequate automation for safe shutdown control.
Solution Approach 2:
The apparatus autonomously determines its own shutdown timing by having the control device inquire about its state and automatically decide when to shut down based on the inquiry results, eliminating the need for continuous user monitoring while conserving battery power through intelligent self-management.
2Reliability
If the control device continuously monitors apparatus state, then shutdown safety is improved, but battery power is depleted during operation
Solution Approach 1:
The system performs state monitoring at predetermined intervals rather than continuously, maintaining adequate shutdown safety through regular checks while preserving battery operation time by avoiding constant monitoring during actual rounds.
Solution Approach 2:
The control device performs preliminary inquiry about apparatus state before initiating shutdown, ensuring safety by checking the state in advance at predetermined intervals rather than requiring continuous monitoring throughout operation.
3Loss of energy
If the apparatus shuts down when connected to external power supply, then battery preservation is improved, but ongoing data transmission is interrupted
Solution Approach 1:
The control device receives feedback about the apparatus state including data transmission status before making shutdown decisions. This feedback mechanism ensures that shutdown actions are taken only when appropriate, preserving battery while avoiding interruption of ongoing data transmission to external devices.
Solution Approach 2:
The system performs preliminary checks of apparatus state and data transmission status before executing shutdown when connected to external power supply, ensuring battery preservation while preventing loss of information by confirming transmission completion or pausing appropriately.

AI summary
A mobile radiographic imaging apparatus includes: two independent power supply units; two control devices each being driven with power supplied from each of the two power supply units; a first hardware processor in one of the two control devices includes; and a second hardware processor in the other one of the two control device. The first hardware processor inquires of the second hardware processor about a state of the other control device when a predetermined condition is satisfied, and shuts down the one control device or cancels shutdown of the one control device according to a response from the other control device.
