Wireless LAN Switching for Reliable Device Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices face challenges in reliably connecting to operation target devices via wireless LAN, especially when the target device is not present on the currently connected network, leading to difficulties in maintaining stable connections and efficient data transmission.
Innovation Solution
An information processing device with a communication controller capable of connecting to multiple wireless LANs, a setting information management unit for storing and switching between networks, and a communication switching unit that identifies and switches to the correct network to find and connect with the operation target device, ensuring seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information processing device connects to a wireless LAN and stores connection information, then it can maintain connection settings for future use, but it cannot connect to the operation target device if the target device is not present on the currently connected network
Solution Approach 1:
The device performs preliminary actions by storing connection information of multiple wireless LANs in advance. When the operation target device is not found on the current network, the device can switch to a previously connected network where the target device might be present, thus resolving the contradiction between maintaining stable connections and adapting to network changes.
2Adaptability or versatility
If the device switches wireless LANs to find the operation target device, then it can maintain connection availability, but it increases the complexity of network management
Solution Approach 1:
The device performs self-service by automatically switching between wireless LANs based on stored connection information without requiring manual user intervention. The control unit autonomously determines which network to switch to and executes the switching operation, thereby reducing the perceived complexity for the user while maintaining high adaptability.
3Reliability
If the device stores information of multiple wireless LANs, then it can switch networks to maintain connection, but it increases the amount of stored information
Solution Approach 1:
The device extracts and stores only the essential connection information needed for network switching, such as SSID and connection parameters, rather than storing complete network configurations or redundant data. This selective extraction maintains connection reliability while minimizing the volume of stored information.

AI summary
An information processing device includes: a communication controller that is able to connect to plural wireless LANs; a setting information management unit that, when connection is made to an operation target device via a wireless LAN, manages setting information including information of a first wireless LAN, which is a wireless LAN as a connection destination, and information of the operation target device; a communication switching unit that, in a case where the operation target device does not exist on a second wireless LAN, which is a wireless LAN currently connected by the communication controller, switches the wireless LAN as the connection destination to the first wireless LAN based on the setting information; and an operation unit that searches for the operation target device on the first wireless LAN to which the communication switching unit has switched the wireless LAN, and if the operation target device exists, connects to the operation target device to operate thereof.
