Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices connected to wireless networks face disconnection issues when switching frequency channels for setting communication parameters, especially when already connected to another network.
Innovation Solution
A communication apparatus with a determination unit to assess network connection status and a control unit to prevent waiting for setting processing if already connected, ensuring continued network connectivity by aborting the setting process if the device is already connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the apparatus switches the operating frequency channel to the frequency channel included in the QR code to wait for search from another apparatus, then the setting processing of communication parameters can be performed more efficiently, but the apparatus may become disconnected from the already-connected wireless network
Solution Approach 1:
The apparatus dynamically adjusts its operating frequency channel based on connection status. When not connected to a wireless network, it switches to the QR code frequency channel to enable setting processing. When already connected, it maintains the current frequency channel, avoiding disconnection. This dynamic adaptation resolves the contradiction between setting efficiency and connection stability.
Solution Approach 2:
The system changes the frequency channel parameter conditionally based on network connection status. The determination unit checks whether the apparatus is connected to a wireless network, and only switches the frequency channel if not connected. This conditional parameter change enables efficient setting processing when appropriate while preserving existing connections.
2Ease of operation
If the apparatus waits for a request for setting processing on the frequency channel included in the QR code, then communication parameters can be set with another apparatus, but the apparatus may disconnect from its current wireless network
Solution Approach 1:
The determination unit performs a preliminary check of the network connection status before the apparatus switches to wait for setting processing requests. This preliminary action prevents disconnection by identifying the need to maintain the current frequency channel when already connected, thus preserving both parameter setting capability and existing network connections.
Solution Approach 2:
The determination unit acts as an intermediary between the waiting unit and the frequency channel switching mechanism. It evaluates the connection status and determines whether frequency channel switching should occur, thus mediating between the need for parameter setting and the need to maintain stable network connections.

AI summary
A communication apparatus determines whether the communication apparatus is connected with a wireless network, and accepts an instruction for starting setting processing of a communication parameter, which is used in performing wireless communication, with another communication apparatus that has read an image including information about a frequency channel used in the setting processing. If the communication apparatus is determined to be connected with the wireless network, the communication apparatus does not start waiting for a request for the setting processing even when the instruction is accepted. If the communication apparatus is determined not to be connected with the wireless network, the communication apparatus starts waiting for the request for the setting processing in response to acceptance of the instruction.
