Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple image-based setting methods are displayed to provide connection options, then connection versatility is improved, but user confusion increases and ease of operation deteriorates
Solution Approach 1:
The system automatically determines the appropriate connection method based on the information processing apparatus's current network state. When the apparatus is connected to an external access point, the system automatically selects infrastructure mode; when not connected, it automatically selects direct connection mode. This eliminates the need for users to manually choose connection methods, resolving the contradiction between providing multiple connection options and avoiding user confusion.
Solution Approach 2:
The system changes the connection mode parameter automatically based on the network environment. By monitoring whether the information processing apparatus is connected to an external access point, the system dynamically adjusts the connection method (infrastructure mode vs. direct connection mode), providing adaptability without requiring user intervention.
2Measurement precision
If users must select a setting method and recognize which image to capture, then connection control precision is improved, but operation complexity increases and ease of operation deteriorates
Solution Approach 1:
The system performs automatic connection method determination without requiring user selection. The communication apparatus monitors the information processing apparatus's network state and automatically chooses the appropriate connection mode, eliminating the need for users to understand or select between different connection methods.
Solution Approach 2:
The system introduces an automatic determination mechanism as an intermediary between the user and the connection method selection. This intermediary automatically analyzes the network environment and selects the appropriate connection method, removing the burden of decision-making from the user while ensuring accurate connection setup.
3Reliability
If communication parameters are concealed using public-key cryptography for security, then information security is improved, but setting complexity increases for users
Solution Approach 1:
The system automatically manages the complex cryptographic authentication process without requiring user intervention. The automatic determination of connection methods and parameters eliminates the need for users to understand or configure security settings, maintaining high security while simplifying the user experience.

AI summary
A communication apparatus displays, on a display unit, to be captured by an information processing apparatus, display information including first information used for communication for establishing, by a first connection method, wireless connection between the communication apparatus and an external access point different from the information processing apparatus and the communication apparatus, and second information for establishing, by a second connection method without intervention of the external access point, wireless connection between the information processing apparatus and the communication apparatus.
