Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radiofrequency sensing is used to monitor the area, then detection accuracy is improved, but the ability to locate a person exactly within the area deteriorates
Solution Approach 1:
The patent combines radiofrequency sensing and audio sensing into a hybrid sensing system. The radiofrequency component provides accurate detection of presence and physiological parameters, while the audio sensing component compensates for the location determination deficiency. The controlling unit integrates data from both sensing modalities to achieve both accurate detection and location capability.
2Loss of information
If audio sensing is used to monitor the area, then location capability is improved, but reliability in noisy environments deteriorates
Solution Approach 1:
The radiofrequency sensing acts as an intermediary that provides reliable detection data in noisy environments where audio sensing alone would fail. The controlling unit uses radiofrequency sensing results to verify and supplement audio sensing data, ensuring reliable detection even when audio signals are degraded by noise.
3Adaptability or versatility
If both radiofrequency sensing and audio sensing are performed independently, then sensing coverage is improved, but coordination and optimality deteriorate
Solution Approach 1:
The controlling unit implements feedback mechanisms where the results from radiofrequency sensing inform the audio sensing configuration and vice versa. The system continuously monitors the performance of both sensing modalities and adjusts their parameters dynamically to optimize overall system performance while maintaining manageable complexity.
