Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calibration procedure is required to balance sound from multiple speakers, then sound quality can be optimized, but user convenience deteriorates and calibration frequency increases
Solution Approach 1:
The system performs self-calibration by automatically detecting speaker output levels using built-in sensors and adjusting speaker properties without requiring user intervention. The calibration process is initiated and executed autonomously by the audio generation hardware, eliminating the need for users to manually position microphones or follow calibration procedures.
Solution Approach 2:
The system continuously monitors sound output from speakers using sensors and uses this feedback to automatically adjust speaker properties. The audio generation hardware receives real-time data on sound levels and automatically modifies speaker settings to maintain optimal sound balance, creating a closed-loop control system that adapts to changing conditions.
2Reliability
If frequent calibration is performed to maintain optimal sound production, then sound quality is preserved, but time consumption increases
Solution Approach 1:
The system performs continuous or near-continuous calibration by automatically monitoring and adjusting speaker properties in real-time. Rather than requiring discrete manual calibration events, the system maintains ongoing optimization through continuous feedback loops that detect and correct imbalances as they occur, eliminating downtime between calibration events.
Solution Approach 2:
The system performs preliminary calibration automatically during initial setup and continuously in the background, so that when users need optimal sound quality, the calibration is already complete. The system proactively adjusts speaker properties before users notice any degradation in sound balance, eliminating the need for users to initiate calibration procedures.
3Ease of operation
If automatic calibration system is implemented, then user convenience is improved, but device complexity increases
Solution Approach 1:
The audio generation hardware performs multiple functions: it generates audio signals, monitors speaker output through integrated sensors, detects sound levels, and automatically adjusts speaker properties. By combining these functions into a single multi-functional system, the patent reduces the need for separate calibration devices and simplifies the overall system architecture despite the added automation capabilities.
