Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming, acoustic echo cancellation and noise reduction technology are applied, then noise reduction performance is improved, but power consumption increases
Solution Approach 1:
The patent segments the audio processing tasks by separating them into different processing stages: local processing (beamforming, acoustic echo cancellation) is performed on the earphone, while noise reduction is performed on the smartphone. This segmentation allows the earphone to perform only essential local processing with lower power consumption, while leveraging the smartphone's computational resources for more demanding noise reduction tasks.
Solution Approach 2:
The patent introduces a task assigning method that acts as an intermediary between the earphone and smartphone. This method dynamically determines which processing tasks should be performed locally versus remotely based on real-time conditions, enabling flexible distribution of computational load and optimizing overall power consumption while maintaining noise reduction performance.
2Ease of operation
If the earphone size is reduced for comfortable wear, then ease of operation is improved, but power storage capacity decreases
Solution Approach 1:
The patent merges the power storage function with the smartphone rather than incorporating a large battery in the earphone. The earphone maintains a small size for comfortable wear while relying on the smartphone's battery capacity to provide sustained power for audio processing tasks, effectively combining the power storage function across multiple devices.
Solution Approach 2:
The patent shifts the power storage dimension from the earphone device to the smartphone ecosystem. Instead of increasing battery capacity within the constrained earphone volume, the system leverages the smartphone's larger battery capacity, effectively moving the power storage constraint to a different dimensional space (from device-level to system-level).
3Speed
If task transmission rate is increased, then processing speed is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic task transmission rate adjustment based on real-time detection parameters. The system continuously monitors battery levels and processing conditions, then dynamically modulates the transmission rate to match actual needs. This prevents unnecessary high-speed transmission when power is constrained, optimizing the balance between processing speed and power consumption.
Solution Approach 2:
The patent employs feedback mechanisms where detection parameters (battery level, processing status) are continuously monitored and fed back to the task assigning method. This feedback loop enables real-time adjustment of task transmission rates, ensuring that processing speed is optimized according to current power availability and system conditions.
