Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If at least three voice acquisition units are arranged to maximize phase differences and sound volume, then noise reduction and voice enhancement performance are improved, but device complexity increases
Solution Approach 1:
The patent transitions from conventional two-dimensional microphone array arrangements to a three-dimensional spatial configuration of voice acquisition units. This dimensional change enables the system to capture sound waves from multiple angles simultaneously, creating complex phase differences that enhance noise reduction capabilities while maintaining voice clarity through sophisticated beamforming processing.
Solution Approach 2:
The patent employs dynamic adjustment of parameters including the spatial positions, orientations, and sampling frequencies of multiple voice acquisition units. By changing these parameters in real-time based on detected sound sources and environmental conditions, the system optimizes noise reduction performance without requiring a fixed complex physical structure.
2Measurement precision
If multiple voice acquisition units are used for beamforming, then user voice clarity is enhanced, but the number of components increases
Solution Approach 1:
Each voice acquisition unit is designed with multi-functionality, serving both as a noise reduction tool and as a voice enhancement component. The units perform multiple tasks including ambient noise cancellation, directional voice pickup, and spatial audio mapping, thereby reducing the need for additional specialized components while maintaining high voice data accuracy.
Solution Approach 2:
The patent merges the functions of multiple voice acquisition units into a unified beamforming system where the collective output of the units is processed together. This merging approach allows the system to achieve high measurement precision through cooperative processing, effectively reducing the perceived complexity despite having multiple physical components.
