Solution Overview
Problem
Existing wireless network connections for audio devices are complex and cumbersome, requiring users to manually set up SSIDs and passwords, and selecting a connection form that minimizes radio wave congestion for high-quality audio signal transmission is troublesome.
Innovation Solution
A method for connecting a new communication device to a network by searching for an arbitrary access point, acquiring system information, and changing the connection destination based on the acquired connection form, utilizing devices with both wireless LAN access point and child device functions, and a control unit that processes communication signals and manages connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless network connection is used to eliminate cables and increase connection freedom, then connection flexibility is improved, but setup complexity increases due to SSID and password configuration requirements
Solution Approach 1:
The new communication device automatically performs network configuration by acquiring system information including connection forms from existing devices in the network. The device independently determines its own connection method (access point or child device mode) without requiring manual SSID or password input, making the system self-configuring and eliminating setup complexity while preserving wireless connection flexibility
Solution Approach 2:
Existing communication devices in the network pre-establish and maintain system information about connection forms and network structure. When a new device joins, this pre-existing information is automatically provided to the newcomer, eliminating the need for the new device to perform complex configuration searches and negotiations, thus reducing setup complexity while maintaining connection freedom
2Reliability
If manual selection of connection form is required to minimize radio wave congestion, then audio signal quality is improved, but user operation complexity increases
Solution Approach 1:
The new communication device automatically acquires system information about existing connection forms and autonomously determines the most appropriate connection method (access point or child device) based on this information. This self-determination process eliminates radio wave congestion without requiring user intervention or manual selection, thus maintaining audio signal quality while reducing operational complexity
Solution Approach 2:
The system uses acquired system information about existing connection forms as feedback to automatically determine the optimal connection method for the new device. This feedback mechanism enables the device to select connection forms that minimize radio wave congestion and ensure high-quality audio transmission without requiring users to understand or manually optimize technical parameters

AI summary
A connection method of a communication device in a communication system that includes a plurality of communication devices (4) each having a wireless LAN access point function and a wireless LAN child device function and is constructed by connecting a lower-level communication device (4) to an access point of a higher-level communication device (4). A new communication device (4-6) to be added to the communication system executes a first step of connecting to an access point (4A) of an arbitrary one of the communication devices (4) in the communication system, and a second step of acquiring, from the connected communication device (4), system information of the communication system including a connection form of the communication devices (4).
