Communication System Automatic Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing connection statuses of communication devices in a networked audio system is complex and cumbersome, especially when compared to traditional wired connections, as wireless networks require setup of SSID and password and are harder for users to manage.
Innovation Solution
The system employs a controller, such as a multifunctional portable phone, to distribute system information to connected devices, allowing for easy management of connections by generating and transmitting SSID and password automatically, and using internal and external access points to facilitate connection and reconnection within the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless network connection is used to eliminate cables and increase connection freedom, then connection flexibility is improved, but setup complexity and management difficulty increase
Solution Approach 1:
The system enables automatic connection management where devices self-register and self-configure in the network. The control device automatically detects newly connected audio devices, assigns them network identifiers, and updates the connection map without requiring manual user intervention for each connection change.
Solution Approach 2:
The system implements automatic feedback mechanisms where the control device continuously monitors network connection status, detects changes in real-time, and automatically updates the connection map. This feedback loop ensures the system state is always synchronized without manual intervention.
2Reliability
If manual management of connection forms is implemented, then connection status can be tracked, but user operation burden increases
Solution Approach 1:
The control device automatically performs connection status tracking by detecting when audio devices connect or disconnect from the network. The system self-updates the connection map data structure to reflect current network topology without requiring users to manually report or update connection states.
Solution Approach 2:
The patent replaces manual mechanical tracking methods with automated electronic monitoring. The control device uses network protocol detection and automatic message exchange to track connection status, substituting manual user actions with automated computational processes.
3Reliability
If system information is distributed to all devices, then connection reliability can be verified, but network traffic increases
Solution Approach 1:
The system distributes system information selectively rather than continuously to all devices. Connection verification messages are sent only when connection status changes or when specifically requested, rather than maintaining constant information synchronization across all network participants.
Solution Approach 2:
The control device acts as an intermediary that centralizes connection management functions. Instead of all devices exchanging information directly with each other, the control device receives connection notifications, verifies status, and distributes only necessary information updates to relevant devices, reducing overall network traffic.

AI summary
A communication system (10) having communication devices (4) which are connected to one another through a network, wherein: a root device (4) which is one of the communication devices stores system information including address information and information on availability of communication of each of the communication devices (4); the root device (4) transmits the system information to each of the communication devices (4) periodically; on receiving the system information, each of the communication devices (4) sends, to the root device (4), an acknowledgement message indicating that the system information has been received; and the root device (4) determines whether the acknowledgement message has been sent from each of the communication devices or not, and, when an acknowledgement message from one of the communication devices (4) has not been received by the root device (4), the root device (4) rewrites the information on availability of communication of that communication device, as incommunicable, and updates the system information accordingly.
