Wireless Relay IP Address Discovery via Default and LAN Fallback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless remote control systems, the interruption and re-establishment of connections between an electronic device and a relay device can result in the electronic device losing communication due to changes in the IP address assigned by the access point, leading to connectivity issues.
Innovation Solution
A connection method where the electronic device sends a connection request command to a default IP address and, if unsuccessful, attempts to connect to other IP addresses in the same local area network, ensuring connection establishment as long as the relay device is connected to the access point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the access point assigns a new IP address to the relay device after connection interruption and re-establishment, then the relay device can be reconnected to the network, but the electronic device cannot connect to the relay device because it still uses the original IP address
Solution Approach 1:
The electronic device performs preliminary actions by sending connection requests to multiple potential IP addresses (including default and alternative addresses) before establishing a confirmed connection. This proactive approach ensures that even if the relay device receives a new IP address after reconnection, the electronic device has already attempted to connect to possible addresses, thereby maintaining connection reliability without losing track of the relay device.
2Ease of operation
If the electronic device only connects to the default IP address, then the connection process is simple, but the connection fails when the relay device receives a different IP address
Solution Approach 1:
The connection process is segmented into multiple stages: first attempting connection to the default IP address, and if that fails, automatically proceeding to attempt connections to alternative IP addresses in the same local area network. This segmentation allows the system to maintain simple initial operation while ensuring reliable connection establishment through systematic fallback options.
3Reliability
If the electronic device sends connection requests to multiple IP addresses, then the connection success rate improves, but the connection process becomes more complex
Solution Approach 1:
The electronic device performs self-service by automatically managing the connection process without requiring user intervention. When the default IP address connection fails, the device autonomously sends connection requests to alternative IP addresses, automatically establishes connections, and handles the entire multi-address connection strategy without adding operational complexity for the user.

AI summary
A connection method for a wireless system, wherein the wireless system includes an access point, an electronic device, a relay device and an appliance; the electronic device and the relay device are connected to the access point, respectively; the relay device is connected to the appliance via signals; the relay device is adapted to send control commands to the appliance; the connection method includes the following steps: sending a connection request command to a default IP address from the electronic device through the access point for at least one time; determining whether a connection-successful information is received from the default IP address or not. Then, establishing a connection between the electronic device and the relay device, or sending at least one connection request command to at least one different IP address in the same local area network from the electronic device.
