QR Code-Based Wireless Connection Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies do not allow users to optionally select whether an electronic device displaying a QR code is connected to a wireless network established by an access point or using Wi-Fi Direct, limiting flexibility in network connections.
Innovation Solution
A communication apparatus that acquires information from a captured image to determine whether to connect using an infrastructure mode based on the IEEE 802.11 standard or Wi-Fi Direct, and provides the necessary communication parameters for the chosen connection method, enabling users to select between these options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication parameters are set in response to imaging of code information (QR code), then electronic devices can be easily connected to a wireless network, but it is not possible to optionally select whether to connect to an access point network or use Wi-Fi Direct
Solution Approach 1:
The patent applies dynamics by making the connection mode selectable and changeable. The determining unit dynamically decides between infrastructure mode and Wi-Fi Direct based on user selection or automatic judgment from the captured image, allowing the system to adapt its connection behavior rather than being fixed to a single mode.
Solution Approach 2:
The patent implements multi-functionality by enabling the communication apparatus to perform both infrastructure mode connection and Wi-Fi Direct connection through the same QR code imaging interface. The system universally supports multiple connection methods, allowing users to select the desired mode while maintaining a unified easy-to-use operation flow.
2Ease of operation
If the system automatically determines connection mode from QR code information, then operation is simplified, but flexibility in selecting connection type is reduced
Solution Approach 1:
The system dynamically adjusts between automatic determination and user-selectable modes. The determining unit can automatically judge the connection mode from the captured QR code information, or alternatively allow user selection, making the system flexible and adaptive to different usage scenarios while maintaining operational simplicity.
Solution Approach 2:
The system provides self-service by automatically determining the connection mode based on the QR code information without requiring user intervention. This automatic judgment capability allows the system to serve itself in determining the appropriate connection type, simplifying operation while the option for user selection remains available when needed.

AI summary
A communication apparatus includes an acquiring unit that acquires information regarding another communication apparatus from a captured image; a determining unit that determines, on the basis of the information acquired by the acquiring unit, whether the other communication apparatus requests a connection using an infrastructure mode based on an IEEE 802.11 standard or requests a connection using Wi-Fi Direct; and a providing unit that provides, to the other communication apparatus, a communication parameter used for a connection requested by the other communication apparatus on the basis of a result of determination by the determining unit.
