Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual setting of mixer parameters is used, then the user can control each parameter precisely, but the setup process becomes time-consuming and inefficient
Solution Approach 1:
The mixer automatically identifies connected audio devices and adjusts parameters without user intervention. The system serves itself by detecting device types through audio signal analysis and autonomously setting optimal parameters for each device, eliminating the need for manual configuration while maintaining precise parameter control.
Solution Approach 2:
The mixer performs preliminary identification of audio devices and pre-configuration of parameters before the user needs to use the system. By analyzing audio signals in advance and automatically setting appropriate parameters based on detected device types, the system prepares the optimal configuration ahead of time, reducing setup time while ensuring precise parameter control.
2Ease of operation
If automatic device identification is implemented, then the setup process is simplified, but the system complexity increases
Solution Approach 1:
The patent replaces manual mechanical adjustment of mixer parameters with automated electronic identification and control. The system uses audio signal analysis and electronic device identification to automatically determine device types and adjust parameters, substituting the mechanical interaction between user and mixer with an electronic automation system that simplifies operation while managing complexity through software-based solutions.
3Loss of information
If watermark information is superimposed on audio signals, then wiring conditions can be easily checked, but the audio signal processing becomes more complex
Solution Approach 1:
Instead of superimposing watermark information on audio signals, the system extracts device identification information directly from the audio signals themselves. By analyzing the inherent characteristics of audio signals from different device types, the system obtains wiring and device connection information without adding external watermarks, thereby reducing signal processing complexity while maintaining full accessibility of wiring information.
