Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wireless pairing method is used, then user can establish connection between devices, but the process requires multiple user confirmations and is cumbersome
Solution Approach 1:
The system performs preliminary actions by automatically selecting and confirming pairing targets based on ultrasonic signal reception before user confirmation is needed. The first communication device proactively initiates pairing by sending broadcast packets and automatically matching with the second device that responds with ultrasonic signals, eliminating the need for manual user confirmations.
Solution Approach 2:
The pairing system performs self-service by automatically completing the pairing process without requiring user intervention. The communication devices autonomously exchange identification information, establish connections, and configure pairing parameters through automated protocols, making the system serve itself rather than requiring user operation.
2Reliability
If broadcast signals are transmitted without spatial limitation, then devices can pair across multiple spaces, but incorrect pairings may occur
Solution Approach 1:
Ultrasonic signals serve as an intermediary medium to establish spatial context for pairing. The system uses ultrasonic propagation characteristics to create a virtual boundary that mediates between the desire for wide pairing range and the need for accurate spatial identification. Only devices within the ultrasonic signal range can complete pairing, ensuring reliability while maintaining adaptability.
Solution Approach 2:
The system changes the parameter of signal propagation by utilizing ultrasonic frequencies that are inaudible to humans but effective for spatial delimitation. This parameter change allows the system to maintain pairing versatility while improving accuracy, as the ultrasonic signals create an imperceptible spatial boundary that prevents incorrect pairings without limiting legitimate pairing opportunities.

Data Source
AI summary
A wireless pairing method, a communication system and a computer-readable storage medium are disclosed. Through the method according to the present disclosure, the second communication device transmits an ultrasonic signal carrying identification information when receiving the first broadcast data packet of the first communication device. Since the penetration performance of ultrasound is limited, the ultrasonic signal of the second communication device is only propagated in a single space, so that the first communication device can transmit a second broadcast data packet externally based on the received ultrasonic signal, so that the second communication device can be paired with the first communication device, thereby realizing automatic pairing of the first communication device and the second communication device in a single space, improving the efficiency of wireless pairing, avoiding incorrect pairing, and improving the user experience.
