Mobile Radiography Power-State Coordination for Shutdown Timing
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 met, and shuts down or cancels shutdown based on the response, optimizing power consumption and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the DR console periodically inquires of the main body about whether the apparatus is in operation to determine shutdown timing, then the apparatus can be shut down appropriately, but power consumption increases due to frequent inquiries
Solution Approach 1:
The main body transmits operation state information to the DR console in advance, eliminating the need for the DR console to repeatedly inquire. The DR console receives push notifications about operation state changes and automatically adjusts its power supply accordingly, performing the necessary action before power is needed rather than continuously checking.
Solution Approach 2:
The system establishes a feedback mechanism where the main body's operation state is automatically communicated to the DR console. The DR console receives real-time feedback about whether the main body is operating and autonomously determines shutdown timing based on this feedback, eliminating manual intervention and reducing unnecessary communication overhead.
2Ease of operation
If the apparatus shuts down when connected to external power supply, then power management is simplified, but image transmission may be interrupted
Solution Approach 1:
The DR console autonomously monitors its own power supply state and the main body's operation state, making independent decisions about shutdown timing. It receives power state information from the power supply unit and combines this with operation state information from the main body to self-determine the optimal shutdown moment, eliminating the need for external control and preventing premature shutdown during image transmission.
3Use of energy by stationary object
If the DR console and main body are independently controlled with separate power supplies, then power efficiency is improved, but coordination difficulty increases
Solution Approach 1:
The power supply unit acts as an intermediary between the main body and DR console. It centrally manages power distribution to both components and transmits power state information to the DR console. This intermediary role simplifies coordination by providing a single point of control for power management while maintaining the independence of the dual power supply configuration.

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.
