Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operation mode is used for audio mixing console, then user can precisely control each parameter, but the operation complexity and time consumption increase significantly
Solution Approach 1:
The system automatically detects audio signal sources and configures signal paths without requiring manual user input for each parameter. The control circuit autonomously analyzes incoming signals, identifies source types, and sets appropriate routing parameters, enabling the system to serve itself rather than requiring continuous user intervention.
Solution Approach 2:
The control circuit pre-configures signal paths by automatically detecting and analyzing audio signals before user operation. The system performs preliminary signal source identification and parameter setup, so that when users need to operate the console, the basic configuration is already in place, reducing both setup time and operational complexity.
2Productivity
If automatic signal path setting is implemented, then setup time is reduced, but the system complexity increases due to additional control circuits and algorithms
Solution Approach 1:
The control circuit is designed to perform multiple functions: it detects external devices, analyzes audio signal characteristics, identifies source types, and configures signal paths. By making the control circuit universal and multi-functional, the patent reduces the need for separate dedicated circuits for each task, thereby managing system complexity while maintaining high productivity.
Solution Approach 2:
The system continuously monitors audio signals and automatically adjusts signal path settings based on real-time signal analysis. This feedback mechanism allows the system to adapt to changing audio sources dynamically, maintaining high processing speed while using intelligent algorithms that optimize control circuit resource utilization.
3Measurement precision
If extensive control elements are provided for all functions, then user control precision is improved, but the ease of operation deteriorates due to the large number of controls
Solution Approach 1:
The control circuit automatically performs signal source detection and path configuration without requiring users to manually adjust multiple control elements. The system serves itself by autonomously analyzing incoming signals and setting appropriate parameters, thereby maintaining control precision while dramatically simplifying user operation.
Solution Approach 2:
The patent extracts the complex signal analysis and configuration tasks from manual user operation and transfers them to automatic control circuit execution. By taking out these complex functions from the user interface domain and implementing them in the control domain, the system maintains precise control capabilities while presenting a simplified operational interface to users.
