Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of human-machine interaction devices with different signal transmission standards are used, then the versatility of the system is improved, but the complexity of the transmission interface increases
Solution Approach 1:
The patent employs a universal audio transmission interface that can handle multiple types of data (audio, control, metadata) through a single standardized channel. The system uses a common digital audio interface format that can carry both traditional audio signals and control data from various human-machine interaction devices, eliminating the need for separate specialized interfaces for each device type.
Solution Approach 2:
The patent introduces an intermediary encoding/decoding mechanism that converts control data from different interaction devices into a standardized audio-compatible format. This intermediary layer translates diverse control protocols into a unified representation that can be transmitted through the audio interface, resolving the complexity of direct multi-standard connections.
2Reliability
If control data and audio data are transmitted separately through different interfaces, then the reliability of data transmission is improved, but the complexity of the transmission system increases
Solution Approach 1:
The patent merges control data transmission with audio data transmission by encoding control information within the audio data stream. Both types of data share the same transmission interface and protocol, reducing the number of separate transmission channels while maintaining reliable delivery through unified error handling and synchronization mechanisms.
Solution Approach 2:
The patent segments the audio data stream into distinct frames or packets, with each segment containing both audio samples and associated control data. This segmentation allows the system to maintain separate logical channels for different data types while physically transmitting them through a single unified interface, preserving reliability through structured data organization.
3Stability of the object's composition
If control information is transmitted at the same sampling rate as audio data, then the synchronization is improved, but the transmission efficiency decreases
Solution Approach 1:
The patent implements periodic synchronization markers or timestamp indicators within the audio data stream at strategically chosen intervals. These periodic synchronization elements allow the receiving system to maintain accurate timing and synchronization between audio playback and control data processing without requiring continuous high-rate transmission of control information, thus improving transmission efficiency while preserving synchronization.
