MFP Network Supervision via Dynamic Role Shifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network systems with multiple MFPs, the need for a dedicated server apparatus with constant power consumption increases costs and disrupts network operations when the MFP with server supervisory functions is turned off, leading to disruptions in the usage of other MFPs.
Innovation Solution
An image formation apparatus capable of autonomously assuming server supervisory functions, shifting these responsibilities among connected MFPs when they are turned off, allowing for continuous network operation without a dedicated server apparatus with constant power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated server apparatus is prepared to supervise network operations, then network supervision reliability is improved, but system cost and power consumption increase
Solution Approach 1:
The patent applies multi-functionality by enabling MFPs to perform both image formation functions and server supervisory functions. The MFPs can operate as both clients and supervisors, eliminating the need for a dedicated server apparatus and reducing overall system power consumption while maintaining network supervision reliability.
Solution Approach 2:
The patent implements self-service by allowing MFPs to autonomously assume server supervisory functions without requiring a separate dedicated server. Each MFP can independently perform supervision tasks, manage licenses, and coordinate network operations, thereby reducing dependency on continuous power supply from a dedicated server.
2Device complexity
If an MFP carries out server supervisory function, then system cost is reduced, but network operation stability deteriorates when the MFP is turned off
Solution Approach 1:
The patent applies dynamics by implementing a flexible supervisor selection mechanism that adapts to the operational status of MFPs. When the current supervisor MFP is turned off, the system dynamically selects a new supervisor from among remaining MFPs, ensuring continuous network operation stability without requiring a dedicated always-on server.
Solution Approach 2:
The patent utilizes parameter changes by monitoring the operational state of MFPs and changing the supervisor role assignment based on power status. The system changes the active supervisor parameter when an MFP is turned off, allowing seamless transition of supervisory responsibilities to maintain network stability.
3Ease of operation
If a dedicated server is used for supervision, then centralized management capability is improved, but adaptability to power status changes deteriorates
Solution Approach 1:
The patent implements a dynamic supervisor election mechanism that adapts to power status changes in real-time. When the dedicated server or primary supervisor MFP loses power, the system automatically elects a new supervisor from available MFPs, maintaining centralized management capability while adapting to changing power conditions.
