Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If UWB communication is used for wireless audio transmission, then high-speed data transmission is achieved, but device information cannot be searched and selected for connection
Solution Approach 1:
The patent segments the connection process into two distinct phases: first using Bluetooth to exchange device information and establish initial connection, then switching to UWB for high-speed audio data transmission. This segmentation allows each communication protocol to perform its optimal function - Bluetooth for device discovery and information exchange, and UWB for high-speed audio streaming.
2Ease of operation
If Bluetooth is used for device connection, then device information can be searched and selected, but high-speed audio transmission cannot be achieved
Solution Approach 1:
The system dynamically switches between Bluetooth and UWB communication modes based on the operational phase. During the connection establishment phase, Bluetooth is used for its device selection capabilities. Once connected, the system transitions to UWB mode to leverage its high-speed transmission capabilities for audio data, optimizing performance for each phase.
3Reliability
If UWB communication is used in complex wireless environments, then stable audio service is required, but connection stability deteriorates
Solution Approach 1:
Bluetooth serves as an intermediary communication layer that facilitates initial connection and device pairing before the UWB connection is established. This intermediary role allows the system to benefit from Bluetooth's robust connection management and device selection capabilities while transitioning to UWB for high-speed audio transmission, thereby mitigating UWB's vulnerability to complex wireless environments during the connection phase.
