Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual vehicle measurements are used without data sharing, then device complexity is reduced, but measurement precision and noise analysis capability deteriorate
Solution Approach 1:
The patent divides the noise measurement task into segments performed by multiple individual vehicles, each equipped with microphones and processing capabilities. Each vehicle independently records and processes sound data, then shares results through communication interfaces. This segmentation allows distributed measurement without requiring a centralized complex system, improving measurement precision through multiple measurement points while keeping individual device complexity manageable.
Solution Approach 2:
The patent combines measurement data from multiple vehicles through wireless communication and data sharing. The control modules exchange sound data and processed information, merging individual measurements into a collective noise analysis resource. This merging enhances measurement precision and noise source localization capability without requiring each individual vehicle to have complex standalone analysis systems.
2Measurement precision
If sound data is shared across multiple vehicles, then noise analysis capability is improved, but loss of time for data processing and communication increases
Solution Approach 1:
The patent implements preliminary processing of sound data at each vehicle's control module before sharing. The control module performs initial analysis, filtering, and feature extraction locally, preparing data in advance for efficient communication. This preliminary action reduces the time required for centralized processing and enables faster noise mapping while maintaining high measurement precision.
Solution Approach 2:
The patent enables continuous sound recording and processing by multiple vehicles simultaneously, with ongoing data exchange and analysis. Rather than batch processing, the system maintains continuous measurement and sharing operations, reducing overall processing time and enabling real-time or near-real-time noise mapping with improved precision.
3Device complexity
If built-in microphones are used for sound recording, then device complexity is reduced, but measurement precision deteriorates due to microphone characteristics and distortion
Solution Approach 1:
The patent incorporates feedback mechanisms where vehicles share information about their microphone characteristics, calibration data, and measured environmental conditions. The control modules use this feedback to compensate for individual microphone distortions and variations, improving sound data accuracy while continuing to use simple built-in microphones rather than complex professional-grade equipment.
Solution Approach 2:
The patent applies parameter changes through signal processing techniques that adjust and normalize sound data from different microphones. The control module processes raw sound data by applying filters, gain adjustments, and calibration corrections, transforming data from microphones with varying characteristics into a unified, accurate noise measurement dataset without requiring expensive specialized hardware.
