Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unique preset algorithm parameter is used for all speaker models, then the device complexity is reduced, but the speaker performance and control accuracy deteriorate
Solution Approach 1:
The patent applies parameter changes by storing multiple preset algorithm parameters in a library, each corresponding to different speaker models. The system retrieves and applies the appropriate parameters based on the specific speaker model being used, allowing optimization of control accuracy for each model while maintaining a standardized management approach through the parameter library structure.
2Manufacturing precision
If multiple preset algorithm parameters are stored for different speaker models, then the speaker control accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-storing multiple sets of algorithm parameters in a parameter library before the speaker needs to be controlled. This allows the system to quickly retrieve the appropriate parameters without performing complex real-time calculations or adjustments, thereby improving control accuracy while minimizing the computational complexity during operation.
3Ease of operation
If the smart PA uses a fixed control method, then the ease of operation is improved, but the adaptability to different speaker models deteriorates
Solution Approach 1:
The patent applies universality by creating a standardized parameter library that can accommodate multiple speaker models. The system uses a universal control interface that automatically selects the appropriate algorithm parameters from the library based on the detected speaker model, thereby maintaining ease of operation while achieving broad adaptability across different speaker types and suppliers.
