Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If Wi-Fi Direct is used for device-to-device communication, then connection speed and transmission distance are improved, but compatibility and consistency of operation are worsened due to lack of standardized software supporting higher layer applications
Solution Approach 1:
The patent implements a universal service discovery mechanism that works across multiple communication interfaces (Wi-Fi Direct, Bluetooth, NFC). The system provides a standardized higher layer application framework that can operate over different physical connections, making the service compatible across diverse device pairs while maintaining fast connection speeds where available.
Solution Approach 2:
The patent introduces an intermediary service discovery protocol that mediates between the physical connection layer and application layer. This intermediary layer provides standardized service discovery and connection management, ensuring compatibility while allowing optimization for specific connection types like Wi-Fi Direct.
2Adaptability or versatility
If multiple communication interfaces (P2P, NAN, BLE, NFC) are supported, then service coverage and adaptability are improved, but device complexity and software complexity are worsened
Solution Approach 1:
The patent segments the communication system into distinct layers: physical interface layer, service discovery layer, and application layer. Each interface (Wi-Fi, Bluetooth, NFC) is handled independently at the physical layer, while a unified service discovery mechanism operates above them, reducing overall system complexity through modular design.
Solution Approach 2:
The patent implements a universal service discovery framework that can operate over multiple communication interfaces simultaneously. This single framework handles service discovery, connection management, and data transmission across Wi-Fi Direct, Bluetooth, NFC, and other interfaces, reducing software complexity compared to implementing separate solutions for each interface.
3Reliability
If service discovery is performed using multiple interfaces, then service discovery reliability is improved, but time consumption and energy usage are worsened
Solution Approach 1:
The patent implements periodic service discovery attempts across multiple interfaces with configurable intervals. Instead of continuous scanning, the system performs discovery at periodic intervals, reducing time and energy consumption while maintaining reliable service discovery through repeated attempts across different interfaces.
Solution Approach 2:
The patent maintains continuous service discovery capability by operating multiple discovery processes in parallel across different interfaces. While individual interface discoveries may take time, the system ensures continuous progress toward reliable service discovery by simultaneously attempting connections through multiple pathways.
