Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple audio-data transmitter devices connect to a single receiver device using existing wireless systems, then the system can support multi-source audio transmission, but latency increases affecting reliability and efficiency
Solution Approach 1:
The patent introduces a relay mechanism where a first audio-data transmitter device acts as an intermediary to relay audio data from a second transmitter device to the receiver device. This mediator approach enables multi-source transmission while reducing latency by optimizing the data path through coordinated relay operations between transmitters and the receiver.
2Productivity
If multiple transmitter devices transmit data simultaneously to a single receiver device, then data transmission capacity increases, but coordination complexity and latency increase
Solution Approach 1:
The patent segments the transmission process by assigning specific data slots to different transmitter devices. The receiver device coordinates transmissions by dividing time into discrete slots, with each slot assigned to a specific transmitter. This segmentation reduces coordination complexity while maintaining multi-source transmission capacity.
Solution Approach 2:
The system implements periodic transmission cycles where transmitter devices alternate in transmitting data during assigned data slots. This periodic structure provides a predictable rhythm to multi-device communication, simplifying coordination while enabling continuous data flow from multiple sources.
3Adaptability or versatility
If existing wireless systems are used for multi-source transmission, then system compatibility is maintained, but transmission efficiency and reliability deteriorate due to increased latency
Solution Approach 1:
The patent implements dynamic relay mode selection where transmitter devices can operate in different modes (normal mode or relay mode) based on current transmission conditions. This dynamic adaptation allows the system to optimize for reliability by switching to relay mode when beneficial, while maintaining compatibility with existing wireless audio transmission standards and protocols.
Data Source
AI summary
The invention relates to methods, non-transitory computer-readable storage medium, and apparatus for transmitting and receiving a wireless multi-source packet. A processing unit of a first audio-data transmitter device obtains data-slot assignments indicating that a first data slot is assigned to a second audio-data transmitter device and a second data slot is assigned to first audio-data transmitter device for data transmission from a audio-data receiver device; tunes in a first physical channel in the first data slot to obtain a first frame from the second audio-data transmitter device; obtains a second frame including a chunk of second audio data originated by the first audio-data transmitter device; encapsulates the first frame and the second frame into a payload of a media packet; and transmits the media packet at a second physical channel to the audio-data receiver device in the second data slot.
