Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple detection methods (Probe Request frame and Service Discovery Frame) are implemented to detect partner STAs, then the compatibility and detection range are improved, but the device complexity and processing overhead increase
Solution Approach 1:
The detection process is segmented into two independent detection methods: first detection method using Probe Request frame and second detection method using Service Discovery Frame. Each method can be executed separately based on security settings, allowing the system to manage complexity by dividing the overall detection function into manageable segments that can be selectively activated.
Solution Approach 2:
The system dynamically selects which detection methods to execute based on the security method settings. When the first security method is set, only the first detection method is executed; when the second security method is set, only the second detection method is executed. This dynamic adaptation allows the system to optimize performance by activating only the necessary detection methods, reducing processing overhead while maintaining compatibility.
2Productivity
If both first and second detection methods are executed simultaneously to maximize detection coverage, then the detection efficiency is improved, but the time consumption and resource usage increase
Solution Approach 1:
The system dynamically adjusts detection behavior based on security settings. When the first security method is configured, the system executes only the first detection method using Probe Request frame, avoiding unnecessary processing of the second detection method. Similarly, when the second security method is set, only the second detection method using Service Discovery Frame is executed. This dynamic selection optimizes detection efficiency by activating only the necessary methods, reducing time consumption while maintaining comprehensive detection coverage.
Solution Approach 2:
The system changes the detection parameters and execution scope based on security method settings. By adjusting which detection methods are activated according to the security configuration, the system optimizes the balance between detection coverage and processing resources, reducing unnecessary time consumption while maintaining efficient detection performance.
3Reliability
If the detecting unit executes detection methods based on set security methods, then the connection establishment accuracy is improved, but the ease of operation decreases
Solution Approach 1:
The detecting unit automatically selects and executes appropriate detection methods based on the security settings configured in the communication apparatus. The system performs self-service by autonomously determining which detection methods to activate without requiring manual user intervention or configuration. This automatic adaptation maintains high connection establishment accuracy while preserving ease of operation, as users simply need to set their security preferences without managing detection process complexity.

AI summary
A communication apparatus that executes a wireless communication method compliant with a Wi-Fi Direct standard detects an existence of an other communication apparatus using a first detection method using a Probe Request frame and a second detection method using a Service Discovery Frame; and establishes a connection with the detected other communication apparatus using a first establishing process associated with the first detection method or a second establishing process associated with the second detection method, wherein, in a case where the first establishing process supports a first security method and the second establishing process supports a second security method, the first detection method is executed based on the first security method being set in the communication apparatus, and the second detection method is executed based on the second security method being set in the communication apparatus.
