Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual network connection method is used, then user can connect to Wi-Fi network, but operation procedure is complex and connection time is long
Solution Approach 1:
The patent applies preliminary action by pre-generating configuration description files containing network connection parameters (SSID, password, encryption type) and embedding them in two-dimensional codes before the user needs to connect. When the user scans the code, the configuration is already prepared and can be automatically installed, eliminating the need for manual entry during the connection process.
Solution Approach 2:
The patent replaces the mechanical manual operation system (typing passwords, selecting networks) with an optical recognition system (two-dimensional code scanning). The user equipment uses a camera or scanner to read the visual code, automatically extracts connection parameters, and installs the configuration file without physical keyboard interaction, thereby substituting manual mechanical operations with automated optical recognition.
2Reliability
If manual password entry is required, then network security can be maintained, but input errors may occur reducing connection efficiency
Solution Approach 1:
The patent uses copying by creating accurate digital replicas of network connection parameters in the form of two-dimensional codes. Instead of manually typing information, the system copies the pre-configured network credentials into a machine-readable format that can be automatically read and installed, eliminating human transcription errors while maintaining security through encrypted configuration files.
3Productivity
If automatic connection is implemented, then connection efficiency is improved, but security verification becomes challenging
Solution Approach 1:
The patent introduces an intermediary mechanism - the configuration description file with digital signature - that mediates between automatic connection and security verification. The file acts as a trusted intermediary containing encrypted network parameters and authentication information, allowing automatic installation while maintaining security through signature verification and encrypted content that only executes authorized connection operations.

AI summary
It is described a network connection method and a user equipment. The method includes that a two-dimensional code is scanned to obtain a character string corresponding to the two-dimensional code; when the character string does not comprise a preset character string, it is determined that the two-dimensional code is a secure two-dimensional code, and two-dimensional code information is obtained according to the character string; the two-dimensional code information is decoded, to obtain data of a target access point; a configuration description file is obtained according to the data of the target access point, the configuration description file being used to connect to the target access point; and the configuration description file is installed into the user equipment, and after detecting the target access point, the target access point is connected to according to the configuration description file.
