Network Interface Redundancy for Printer Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses, such as printers, are unable to continue printing operations when a network disorder occurs, as they rely on a single network interface, leading to interruptions until the disorder is manually resolved.
Innovation Solution
The apparatus employs multiple network interfaces to determine and switch to a non-disordered interface, allowing continuous operation by rerouting communication through an unaffected network interface, thereby maintaining connectivity and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single network interface is used for printing operations, then the device complexity is reduced, but the reliability of continuous printing operations deteriorates when network disorders occur
Solution Approach 1:
The network interface functionality is segmented into multiple independent network interfaces, each capable of handling printing operations independently. This segmentation allows the system to isolate network disorders to specific interfaces while maintaining operational continuity through other interfaces.
Solution Approach 2:
The system dynamically changes the operational parameter of network interface selection based on detected network conditions. When a disorder is detected on one interface, the system switches to a different network interface, effectively changing which parameter (interface) is active to maintain reliability.
2Reliability
If multiple network interfaces are provided for redundancy, then the reliability of printing operations is improved, but the device complexity increases
Solution Approach 1:
The network interface management system performs self-service by automatically detecting network disorders and switching between interfaces without requiring user intervention. The system monitors its own network conditions and autonomously selects the appropriate interface, reducing the perceived complexity for users.
Solution Approach 2:
The system implements feedback mechanisms where network status is continuously monitored and this information feeds back into the interface selection logic. This feedback loop enables automatic adaptation to network conditions, managing the complexity of multiple interfaces through intelligent control.
3Productivity
If automatic network interface switching is implemented, then the productivity is maintained during network disorders, but the ease of operation is reduced due to automated control mechanisms
Solution Approach 1:
The automatic interface switching system serves itself by autonomously monitoring network conditions and performing switch operations without user involvement. This self-service capability maintains productivity during disorders while actually simplifying ease of operation, as users do not need to manually manage interface selections.

AI summary
An image forming method, an image forming apparatus, and a host include determining if a disorder is generated in a network set to perform an operation among networks between an image forming apparatus including at least two network interfaces and a host, and if a disorder is generated in the set network, networking the image forming apparatus with the host via a non-disordered network interface.
