Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one audio sink device plays audio streams from multiple audio source devices, then audio versatility and user experience are improved, but device complexity and audio stream management difficulty increase
Solution Approach 1:
The patent introduces an audio mixing device as an intermediary component between multiple audio source devices and the audio sink device. This mixing device receives audio streams from multiple sources, performs mixing processing based on indication information, and outputs the mixed audio to the sink device. By inserting this intermediary, the complexity of managing multiple audio streams at the sink device is shifted to the mixing device, allowing the sink device to maintain simple single-stream playback capability while achieving multi-source audio versatility.
2Manufacturing precision
If audio mixing weight is dynamically adjusted based on indication information, then audio quality and user experience are improved, but processing time and computational complexity increase
Solution Approach 1:
The patent applies preliminary action by having audio source devices send indication information about their audio streams before the actual mixing process. This indication information (containing stream type, coding format, source device type, etc.) is prepared and transmitted in advance, allowing the mixing device to pre-determine appropriate mixing weights without waiting for real-time analysis during audio playback. This preliminary preparation reduces computational delay during the critical audio mixing operation.
Solution Approach 2:
The patent utilizes parameter changes by adjusting audio mixing weights as configurable parameters based on the indication information received from audio source devices. Instead of complex real-time audio analysis, the system changes the mixing parameters (weights) according to predefined rules based on stream characteristics. For example, different mixing weights are applied depending on whether the stream is music, voice, or notification type, enabling precise audio quality control through parameter adjustment rather than complex processing.
