Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the service discovery function is implemented to identify partner apparatus and exchange service information, then the user convenience is improved, but the number of user operations increases due to required disconnection and reconnection based on wireless LAN connection state
Solution Approach 1:
The communication apparatus automatically determines its own role (base station or terminal) based on the connection state of the partner apparatus, eliminating the need for user intervention. The system performs self-service by autonomously executing role switching and connection management without requiring user operations.
Solution Approach 2:
The system continuously monitors the wireless LAN connection state of the partner apparatus and adjusts its role accordingly. This feedback mechanism allows the communication apparatus to automatically adapt its configuration based on real-time connection status, resolving the contradiction between service discovery functionality and operational complexity.
2Ease of operation
If the communication apparatus autonomously controls wireless connection by determining device roles using Wi-Fi Direct protocols, then user operations are reduced, but the device complexity increases due to integrated control units and functional blocks
Solution Approach 1:
The communication apparatus integrates both base station and terminal functions within a single device, allowing it to perform multiple roles universally. This multi-functionality enables the apparatus to adapt to different connection scenarios without requiring separate devices, reducing user operations while managing complexity through integrated design.
Solution Approach 2:
The system dynamically switches between base station and terminal modes based on the partner apparatus's connection state. This dynamic role assignment allows the communication apparatus to optimize its configuration in real-time, reducing user operations while the complexity is managed through automated control logic.
3Reliability
If manual disconnection and reconnection is required based on device roles in wireless LAN connection, then connection accuracy is maintained, but the connection time increases
Solution Approach 1:
The communication apparatus determines the appropriate role (base station or terminal) in advance based on the partner apparatus's connection state before establishing the connection. This preliminary role determination eliminates the need for manual disconnection and reconnection, maintaining connection accuracy while significantly reducing connection time.
Solution Approach 2:
The system automatically manages the connection process by autonomously determining roles and executing appropriate connection procedures without user intervention. This self-service approach maintains connection reliability while eliminating the time loss associated with manual disconnection and reconnection operations.

AI summary
A communication apparatus has a base station function and a terminal function, and performs communication using at least one of the base station function and the terminal function. The communication apparatus identifies a partner apparatus for communication among one or more other communication apparatuses based on a service to be executed by the communication apparatus and services to be executed by the other communication apparatuses, and decides whether the communication apparatus uses the base station function or the terminal function when connecting to the partner apparatus, based on the execution states of the base station functions and terminal functions of the communication apparatus and the partner apparatus.
