Portable Terminal Barcode Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face difficulties in establishing network connections due to limited screen size, requiring multiple key inputs for network configuration, which can lead to errors and security information leakage through vocal communication.
Innovation Solution
A method and apparatus that generate and capture code images containing network information, using one-dimensional or two-dimensional barcodes, to simplify the network configuration process by acquiring necessary information from a peripheral device and executing automatic programs for secure connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple key inputs are used for network configuration on portable terminals, then network connection can be established, but input errors occur and security information may leak through vocal communication
Solution Approach 1:
The patent replaces the mechanical keyboard input system with an optical recognition system. Instead of requiring users to manually input network configuration parameters through multiple key presses, the system captures an image of the code displayed on the peripheral terminal's screen using the camera module, automatically recognizes the parameters, and configures the network connection. This substitution eliminates input errors and security leaks while maintaining connection reliability.
Solution Approach 2:
The patent uses the camera module to capture an optical copy (image) of the code displayed on the peripheral terminal's screen. This optical copy contains all the necessary network configuration parameters (SSID, password, IP address, etc.). The system then extracts and processes this copied information to establish the network connection, replacing the need for manual transcription of multiple parameters.
2Reliability
If manual key input is required for network configuration, then network connection can be established, but the process becomes time-consuming and error-prone
Solution Approach 1:
The peripheral terminal prepares the code image in advance, displaying all necessary network configuration parameters (SSID, password, IP address, gateway, DNS) in a machine-readable format on its screen. This preliminary preparation eliminates the need for the portable terminal to manually input each parameter during the connection process, significantly reducing setup time and eliminating input errors.
Solution Approach 2:
The patent replaces the time-consuming manual key input process with automated optical recognition. The camera module captures the code image, and the processor automatically extracts and configures all network parameters from the recognized code, establishing the connection without requiring the user to manually type each parameter, thereby eliminating both errors and time delays.
3Area of stationary object
If network configuration information is displayed on the portable terminal screen, then users can view the information, but the limited screen size provides only limited visual content
Solution Approach 1:
The patent transitions from a two-dimensional limited screen display to utilizing the three-dimensional space of the peripheral terminal's display screen. By capturing an image of the code displayed on the peripheral terminal's screen (which has a larger display area), the system can accommodate and display all necessary network configuration parameters without the constraints of the portable terminal's limited screen real estate.

AI summary
An apparatus and method for establishing a network connection in a portable terminal. The apparatus includes a controller (100), an image acquisition unit (108), and a code image analyzer (106). The controller (100) establishes a network connection with a peripheral terminal (703) using network information acquired through a code image. The image acquisition unit (108) captures the code image generated by the peripheral terminal (703). The code image analyzer (106) analyzes the code image acquired by the image acquisition unit (108) and acquires the network information of the peripheral terminal (703). The code image includes at least any one of network information of the peripheral terminal (703), code image generation information, and information on an automatic execution program to be automatically executed after code image recognition.
