Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio signals from multiple parties are transmitted without compensation, then the communication session can proceed with minimal processing, but signal quality inconsistency and noise problems multiply especially in conference calls
Solution Approach 1:
An audio compensation module is introduced as an intermediary component that receives audio signals from multiple communication parties, analyzes their respective signal qualities, and applies compensatory processing. This mediator equalizes signal levels and reduces noise across different audio streams before transmission, ensuring consistent signal quality without requiring complex processing at each endpoint device.
Solution Approach 2:
The system continuously monitors the quality characteristics of incoming audio signals from different parties and dynamically adjusts compensation parameters based on real-time measurements. By measuring signal level differences and noise characteristics, the system applies adaptive equalization and noise reduction, creating a feedback loop that maintains consistent audio quality throughout the communication session.
2Reliability
If audio signals are amplified to compensate for weak signals, then signal quality improves, but noise levels also increase
Solution Approach 1:
The audio compensation module applies different processing strategies to different audio signals based on their individual characteristics. For weak signals, selective amplification is applied only to the desired voice frequency ranges while applying noise reduction algorithms specifically targeted at noise frequency spectra. This local quality approach ensures that each signal is optimized independently, improving signal quality without proportionally amplifying noise.
3Stability of the object's composition
If all audio signals are transmitted at equal levels, then signal consistency is achieved, but dynamic range and voice clarity are reduced
Solution Approach 1:
The system dynamically changes audio signal parameters including gain, equalization filters, and noise reduction thresholds based on the measured characteristics of each participant's audio signal. By adjusting these parameters in real-time, the system maintains consistent overall signal levels while preserving the unique spectral characteristics and clarity of each voice through selective frequency enhancement and adaptive processing.
