Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor devices capture and monitor Wi-Fi transmissions from mobile devices, then measurement precision of device quantity and transmission quality is improved, but device complexity and data processing requirements increase
Solution Approach 1:
The system divides the monitoring function into distributed sensor devices that each independently capture Wi-Fi transmissions and extract device identifiers and signal strength information. Each sensor device operates autonomously to reduce central processing complexity while maintaining high measurement precision through localized data collection.
Solution Approach 2:
The patent introduces sensor devices as intermediary components between mobile devices and the central monitoring system. These sensor devices capture Wi-Fi transmissions and process intermediate data locally before transmitting aggregated results to the server, reducing the complexity burden on the central system while preserving measurement accuracy.
2Loss of information
If the system monitors and analyzes Wi-Fi protocol management transmissions, then information completeness about mobile devices is improved, but loss of time for data processing and analysis increases
Solution Approach 1:
The sensor devices perform preliminary extraction of device identifiers and signal strength information directly from captured Wi-Fi transmissions before data is transmitted to the server. This preliminary processing reduces the amount of data that needs to be analyzed centrally, maintaining information completeness while reducing processing time.
Solution Approach 2:
The system extracts only the essential information elements (device identifiers and signal strength) from the complete Wi-Fi protocol management transmissions. By taking out only the necessary data elements for analysis rather than processing entire transmission packets, the system maintains information completeness for monitoring purposes while significantly reducing data processing time.
3Reliability
If multiple sensor devices are deployed to cover a geographical area, then measurement coverage and reliability are improved, but device complexity and system cost increase
Solution Approach 1:
The patent combines multiple sensor devices into a coordinated network that shares data and monitoring responsibilities. Each sensor device captures transmissions within its coverage area, and the central server aggregates data from all sensors to provide comprehensive device quantity and transmission quality measurements across the entire geographical area, improving reliability through redundancy and coverage.
