Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple devices are used to handle different protocols separately, then each device can process its specific protocol reliably, but the system complexity and number of devices required increases
Solution Approach 1:
The audio interface is designed to universally handle multiple different protocols (MADI, AES67, Dante, AVB) through a single device. The processor receives data signals from various devices utilizing different protocols and generates multitrack audio data by storing digital audio signals from devices using different protocols in separate channels, allowing one device to perform multiple protocol handling functions simultaneously
2Reliability
If separate recording devices are used for each protocol, then each device can be optimized for its specific function, but the overall system cost and complexity increases
Solution Approach 1:
The patent merges multiple separate recording and processing functions into a single audio interface device. The processor combines data signals from multiple devices using different protocols into unified multitrack audio data, eliminating the need for separate dedicated recording devices for each protocol while maintaining optimized handling of each protocol type
3Measurement precision
If time code synchronization is used for coordinating multiple devices, then synchronization precision can be achieved, but the system requires additional synchronization infrastructure and complexity
Solution Approach 1:
The audio interface acts as an intermediary that receives data signals from multiple devices and automatically synchronizes them by storing each protocol's digital audio signal in separate channels of multitrack audio data. This eliminates the need for external time code synchronization infrastructure, as the system achieves synchronization through the processor's inherent ability to handle and organize multi-protocol signals
