Two-Dimensional Code Generation for Wireless Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face unnecessary network changes and additional authentication steps when connecting mobile terminals to communication devices with wireless LAN functions, especially when reading two-dimensional bar codes that include service set identifiers (SSIDs), leading to increased user workload and potential network disruptions.
Innovation Solution
A communication apparatus generates and outputs two-dimensional codes, one including the SSID for direct wireless communication and another without the SSID for infrastructure connection, allowing users to switch between them based on their needs, thereby reducing unnecessary network changes and authentication requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the two-dimensional bar code includes the SSID of the access point, then the mobile terminal can easily connect to the communication apparatus, but an unnecessary network changeover occurs when the mobile terminal is already connected to a network
Solution Approach 1:
The patent segments the connection information into two distinct two-dimensional bar codes: one containing SSID for direct wireless connection and another without SSID for infrastructure connection. This segmentation allows users to select the appropriate connection type, preventing unnecessary network changeovers while maintaining ease of connection.
2Productivity
If the mobile terminal reads the two-dimensional bar code including SSID, then wireless communication is established, but additional authentication work is required when network changeover occurs
Solution Approach 1:
The patent enables preliminary selection of connection type by providing two distinct bar codes before connection occurs. By choosing the SSID-excluded bar code when infrastructure connection is needed, the system performs the connection setup in advance without triggering unnecessary authentication processes, thus eliminating time loss.
3Device complexity
If only one type of two-dimensional bar code is provided, then the device complexity is low, but the adaptability to different connection scenarios is limited
Solution Approach 1:
The patent implements multi-functionality by generating two types of two-dimensional bar codes from the same communication apparatus. Each bar code serves a different connection scenario (direct wireless vs. infrastructure connection), making the system universally applicable to various connection needs without increasing operational complexity for the user.

AI summary
A communication apparatus having a direct wireless communication function includes a generation unit configured to generate a first two-dimensional code including an address of the communication apparatus and an SSID corresponding to the direct wireless communication function, and a second two-dimensional code including the address of the communication apparatus and not including the SSID corresponding to the direct wireless communication function, and an output unit configured to output the first two-dimensional code and the second two-dimensional code.
