Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method that allows a sub-device to conveniently reconnect to a WLAN network using the connection information of a mobile terminal without requiring the user to manually search and select the network.
Innovation Solution
An electronic device with a communication module, processor, and memory that sends a request for connection information to a second device when the connection to a network is interrupted, allowing it to reconnect based on the received information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sub-device connects to a WLAN network manually, then the connection can be established, but the reconnection process becomes complex and requires user intervention when the connection is interrupted
Solution Approach 1:
The patent stores WLAN connection information (SSID, password, etc.) in advance in the sub-device's memory during the initial connection phase. When connection interruption occurs, the pre-stored information is automatically retrieved and used for reconnection, eliminating the need for user intervention and simplifying the reconnection process while maintaining connection reliability
Solution Approach 2:
The sub-device autonomously performs the reconnection process by automatically detecting connection status, retrieving stored connection information from its own memory, and initiating reconnection without requiring user input. This self-service mechanism reduces operational complexity and improves ease of reconnection
2Reliability
If the sub-device stores WLAN connection information locally, then reconnection can be performed automatically, but security risks increase due to potential exposure of connection credentials
Solution Approach 1:
The patent introduces the mobile terminal as an intermediary that securely manages and transmits connection information. Instead of the sub-device directly storing sensitive credentials, the mobile terminal acts as a secure intermediary that provides connection information only when needed, reducing security risks while maintaining reconnection reliability through controlled information sharing
Solution Approach 2:
The system creates a temporary copy of connection information in the sub-device's memory for automatic reconnection purposes only. The original secure storage remains in the mobile terminal, and the copied data is used transiently for reconnection without exposing long-term security credentials, balancing reliability with security
3Speed
If the sub-device automatically requests connection information from the mobile terminal, then reconnection speed improves, but communication overhead between devices increases
Solution Approach 1:
Connection information including SSID, password, and network parameters is stored in advance in the sub-device's memory during the initial connection phase. When connection interruption occurs, the sub-device immediately retrieves this pre-stored information and initiates reconnection without requiring real-time communication with the mobile terminal, thereby improving reconnection speed while minimizing communication overhead
