Communication Apparatus Selective QR Code Display for DPP Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of wireless communication devices face complexity and confusion when setting communication parameters, particularly when multiple schemes are available, leading to difficulties in determining which QR code image to capture for parameter settings.
Innovation Solution
A communication apparatus that generates and displays either a first image encoding communication parameters or a second image encoding authentication information, allowing users to select the appropriate setting scheme based on accepted information, thereby reducing complexity and displaying only one QR code image for parameter setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple QR code images are displayed for different setting schemes, then more setting options are provided, but user confusion increases and ease of operation deteriorates
Solution Approach 1:
The patent introduces an external terminal device as an intermediary to determine which QR code image to display. The communication apparatus receives determination information from the external terminal, and based on this intermediary's decision, only the appropriate QR code image is displayed. This resolves the contradiction by letting the intermediary (external terminal) make the selection, thereby providing adaptability through multiple schemes while maintaining ease of operation by showing only one QR code at a time.
2Adaptability or versatility
If communication parameters are provided through multiple schemes, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-service mechanism where the external terminal device automatically determines and communicates the appropriate setting scheme to the communication apparatus. The communication apparatus does not need to manually manage multiple QR code displays or determine which scheme to use; instead, it receives determination information from the external terminal and automatically displays the corresponding QR code. This reduces device complexity while maintaining versatility through multiple setting schemes.
3Reliability
If authentication information is included in QR code, then security is improved, but information encoding complexity increases
Solution Approach 1:
The patent applies local quality by encoding different types of information in different QR code images based on the setting scheme. In the first setting scheme, communication parameters are encoded in the QR code. In the second setting scheme, only authentication information (public key) is encoded in the QR code, while communication parameters are transmitted separately through a communication channel. This allows security to be improved through authentication information encoding without unnecessarily increasing complexity for all QR codes, as each QR code is optimized for its specific purpose.

AI summary
In order to enable a reduction in complexity in setting a communication parameter, a communication apparatus operable to provide a communication parameter to an external apparatus, generates a first image that is used in a first setting scheme for providing a communication parameter and in which information including a communication parameter is encoded; and generates a second image that is used in a second setting scheme for providing a communication parameter and in which information that does not include the communication parameter and that does include authentication information for performing an authentication is encoded. Then, the apparatus accepts information used to determine which of the first setting scheme and the second setting scheme to use; and, displays, based on the information, either the first image or the second image.
