Smart Appliance Wireless Configuration via AP Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring smart appliances to connect to wireless networks are inconvenient, especially for appliances without display units or those difficult to operate by hand, as they require manual entry of SSID and password, and complicate remote control operations, especially when multiple appliances are involved or network changes occur.
Innovation Solution
A wireless network configuration method where a smart appliance automatically starts an access point mode and connects to a portable electronic device, which can remotely send stored SSID and password for connection, then switches to a hidden SSID mode, allowing direct connection and remote control while avoiding complex network lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the smart appliance uses AP mode for network configuration, then remote control operation is enabled, but the portable electronic device cannot search for the appliance via scanning wireless networks
Solution Approach 1:
The smart appliance dynamically switches between AP mode and hidden SSID mode based on connection status. When connected to the wireless network, it uses hidden SSID mode to remain connectable to the portable electronic device. When connection is lost or during initial configuration, it switches to AP mode to allow discovery and reconnection, thus adapting to different operational states.
2Loss of time
If the portable electronic device stores SSID and password for automatic connection, then configuration time is reduced, but security risk increases
Solution Approach 1:
The portable electronic device performs preliminary action by storing the SSID and password in advance before the actual connection process. This allows the smart appliance to automatically connect without requiring manual input during configuration, significantly reducing setup time while the stored credentials remain secure in the device's memory.
3Reliability
If the smart appliance switches to hidden SSID mode after connection, then network security is improved, but the appliance becomes undetectable in wireless network lists
Solution Approach 1:
The portable electronic device serves as an intermediary between the user and the smart appliance. Even when the appliance is in hidden SSID mode and not detectable in wireless network lists, the intermediary device maintains the connection and enables user control, thus achieving security through hidden SSID while preserving detectability and controllability through the intermediary.
4Reliability
If manual entry of SSID and password is required, then security is maintained, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service by automatically transmitting the stored SSID and password from the portable electronic device to the smart appliance without requiring manual user input. This eliminates the inconvenience of manual entry while maintaining security, as the credentials are automatically provided by the trusted portable device rather than being entered by the user.

AI summary
A wireless network configuration method and system for a smart appliance, wherein the smart appliance can start a client mode and an AP mode to connect with a wireless network AP and a portable electronic device separately. When the smart appliance established the connection with the wireless network AP, it will switch from the AP mode to a hidden SSID mode automatically. If an SSID and password of the access point have been stored in the portable electronic device, the portable electronic device will transmit these data to the smart appliance to simplify the operation for wireless network configuration. Besides, the smart appliance will keep connecting with the portable electronic device and disappearing in an available wireless network list of the portable electronic device in the hidden SSID mode. The advantages of this invention are full function and ease of operation.
