Power Source Switching for Server Continuity in MFPs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-Functional Peripherals (MFPs) face challenges in maintaining functionality when one of their power sources fails, particularly the server power source, without incurring additional costs by providing a second server power source.
Innovation Solution
Incorporating a data processing apparatus with a first and second processor, a power source for each, a detector for abnormality, and a switcher to redirect power from the first processor to the second processor upon detecting an abnormality in the second power source, allowing the MFP to continue operation using the existing MFP power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a second server power source is provided to duplex the server power source, then the server function can continue without stopping even when a failure occurs in the original server power source, but the cost increases
Solution Approach 1:
The MFP power source is designed to serve dual purposes: it powers the MFP functioning part during normal operation and can alternatively power the server functioning part when the server power source fails. This multi-functionality eliminates the need for a dedicated second server power source while maintaining server function continuity.
Solution Approach 2:
The patent merges the backup power capability into the existing MFP power source rather than adding a separate second server power source. The switcher component enables the MFP power source to be dynamically allocated to either the MFP processor or the server processor, combining the backup function with the existing power infrastructure.
2Reliability
If the MFP power source is used to power the server processor when server power source fails, then the server function can continue without stopping, but the MFP functioning part must stop operation
Solution Approach 1:
The system implements dynamic power source allocation through the switcher component, which can reallocate the MFP power source to the server processor when needed. This dynamic switching capability allows the system to adapt its power distribution based on operational priorities and failure conditions.
Solution Approach 2:
The detector component continuously monitors the server power source status and proactively triggers the power source switching before complete server function failure occurs. This preliminary detection and response mechanism ensures smooth transition of power allocation to maintain server continuity.
3Reliability
If a detector and switcher are added to enable power source switching, then the server function can continue when power source abnormality occurs, but the device complexity increases
Solution Approach 1:
The switcher acts as an intermediary component that manages power distribution between the MFP power source and the processors. This dedicated switching mechanism provides a controlled and reliable method for reallocating power without requiring complex reconfiguration of the entire power distribution system.
Solution Approach 2:
The detector provides continuous feedback on the server power source status to the control logic, which then activates the switcher when abnormality is detected. This feedback mechanism enables automatic, responsive power source switching without requiring manual intervention or complex monitoring systems.
Data Source
AI summary
A data processing apparatus includes a first processor, a second processor, a first power source which performs electric power supply to the first processor, a second power source which preforms electric power supply to the second processor, a detector which detects an abnormality of the second power source, and a switcher which is capable of switching a power supply target of the first power source between the first processor and the second processor. When an abnormality of the second power source is detected, the first processor stops an operation of the first processor, and the switcher switches the power supply target of the first power source from the first processor to the second processor after the operation of the first processor is stopped.
