Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If triangulation techniques are used to locate mobile phones, then location accuracy is improved, but system cost and complexity increase
Solution Approach 1:
The patent introduces wireless packet analyzers as intermediary devices that capture Wi-Fi and Bluetooth data packets from mobile devices. These analyzers act as mediators between the sensor system and the mobile devices, extracting unique identifiers without requiring complex triangulation infrastructure. The packet analyzers process communication data to identify devices, eliminating the need for expensive cellular tower triangulation systems while maintaining identification accuracy.
2Difficulty of detecting and measuring
If video surveillance alone is used to detect incidents, then incident detection capability is improved, but ability to ascertain specific identity deteriorates
Solution Approach 1:
The patent merges incident detection capabilities with mobile device identification by combining video surveillance data with wireless packet analyzer data. The system integrates multiple data sources: camera footage for incident detection and location tracking, and Wi-Fi/Bluetooth packet data for unique device identification. This fusion allows the system to not only detect incidents and track suspect movement but also definitively identify individuals by correlating their mobile device identifiers with observed locations and behaviors.
3Difficulty of detecting and measuring
If intelligent sensors are used to track targets, then tracking capability within coverage area is improved, but tracking capability beyond coverage area deteriorates
Solution Approach 1:
The patent extends tracking capability beyond the physical coverage area of intelligent sensors by adding a wireless communication dimension. Instead of relying solely on line-of-sight sensor coverage, the system uses Wi-Fi and Bluetooth wireless signals that can penetrate barriers and extend detection range. Wireless packet analyzers capture data packets from mobile devices even when targets are outside the optical or acoustic range of traditional sensors, effectively adding a new detection dimension that expands the operational area.
4Measurement precision
If multiple cell phone carriers are accessed for tracking, then unique identification accuracy is improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts unique identifying information directly from mobile devices using wireless packet analyzers, eliminating the need to interface with multiple cell phone carriers. Instead of relying on carrier networks for device identification, the system captures Wi-Fi MAC addresses, Bluetooth identifiers, and other wireless data packets directly from the devices themselves. This extraction approach simplifies the system architecture by removing carrier infrastructure dependencies while maintaining the ability to uniquely identify devices through their wireless communication signatures.

AI summary
A method of tracking a target including detecting and localizing an incident in a first area using a first sensor system; determining a target within a plurality of targets associated with the incident in the first area; and tracking the target from the first area to a second area using a second sensor system. The method further includes collecting unique identifiers for the plurality of targets using wireless packet analyzers and determining a digital identity of the target in the first area based on a correlation between the tracking of the target and the unique identifiers collected by the first and second wireless packet analyzers.
