Image Processing Device Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing image processing systems, when an image processing device switches its connection from a server to another information processing device, it can lead to the server user being unable to utilize the image processing device despite their intention, causing unforeseen inconveniences.
Innovation Solution
The image processing device implements a cloud printing system that allows it to establish direct connections with other devices while maintaining a connection with the cloud server, ensuring that the server user is notified and given the option to permit or deny direct connections, thereby preventing unintended disconnections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the image processing device establishes a direct connection with an information processing device, then communication speed and direct access are improved, but the server user becomes unable to utilize the image processing device causing unforeseen inconveniences
Solution Approach 1:
The patent implements dynamic connection management where the image processing device can switch between connection modes (direct connection mode and server connection mode) based on operational needs. The controller dynamically adjusts the connection state, allowing the device to be directly connected to an information processing device for high-speed communication when needed, while maintaining the ability to connect to the server for shared access scenarios, thus resolving the contradiction between speed and availability.
Solution Approach 2:
The patent changes the connection parameter state to resolve the contradiction. By switching the connection mode parameter between 'direct connection' and 'server connection' states, the system can optimize for either communication speed (direct connection) or server user availability (server connection), preventing the scenario where direct connection inadvertently blocks server access.
2Ease of operation
If the image processing device switches connection destination from server to another device, then direct communication is enabled, but unintended disconnection occurs causing user inconvenience
Solution Approach 1:
The patent applies preliminary action by notifying the server user before the image processing device switches its connection destination from the server to another device. The notification unit sends a notification to the server user's device, giving them advance warning of the impending connection change. This allows the user to take preliminary actions (such as saving work or being alerted) before the disconnection occurs, preventing unintended inconvenience while still enabling direct communication when needed.

AI summary
An image processing device is provided that includes an establishment unit configured to establish a first connection with a first information processing device, a detector configured to detect a connection request that requests the image processing device to terminate the first connection with the first information processing device and thereafter establish a second connection with a second information processing device, the second connection being an exclusive connection configured to forbid establishment of connections other than the second connection while being established, and a restriction unit configured to restrict the second connection with the second information processing device from being established when the detector detects the connection request in a state where the first connection is established between the image processing device and the first information processing device.
