Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Wi-Fi access point devices are used to detect unauthorized devices, then detection capability is provided, but positioning accuracy deteriorates and signal dead spots occur
Solution Approach 1:
The patent introduces movable locators as intermediary devices that roam throughout the detection area to collect signal data from unauthorized devices. These locators serve as mobile intermediaries between the detection system and unauthorized devices, eliminating the need for fixed infrastructure and avoiding signal dead spots that plague Wi-Fi AP-based systems.
Solution Approach 2:
The system transitions from static Wi-Fi access points to dynamic movable locators that continuously move through the detection area. This dynamic approach allows the system to adapt to changing spatial conditions, ensure comprehensive coverage, and maintain reliable detection without creating signal dead spots.
2Reliability
If sniffers are deployed in the factory environment to inspect unauthorized devices, then detection capability is improved, but additional arrangement cost increases
Solution Approach 1:
The movable locators are designed as multi-functional devices that combine signal sniffing, location positioning, and data processing capabilities in a single portable unit. This universal design eliminates the need for separate sniffer deployments and complex infrastructure setup, reducing both cost and complexity while maintaining high detection reliability.
Solution Approach 2:
The system employs self-contained movable locators that autonomously navigate, detect, and report unauthorized devices without requiring external infrastructure or complex arrangement. Each locator independently performs detection and transmits data, simplifying the overall system setup and reducing deployment costs.
3Measurement precision
If multiple locators are used to improve positioning accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent merges data from multiple movable locators into a unified detection system that collectively improves positioning accuracy. By combining the observations and signal data from multiple locators, the system achieves high measurement precision while managing complexity through centralized data processing and coordination.

AI summary
A detecting system for an unauthorized device having a movable locator is disclosed. The movable locator includes a location positioning unit, a signal sniffing unit, a signal collecting unit, and a device positioning unit. The location positioning unit detects a locator position of the movable locator. The signal sniffing unit detects Wi-Fi signal of an unauthorized device and generates a sensing report message. The signal collecting unit adds multiple sensing report messages to a sensing report record collection. The device positioning unit organizes multiple positioning combinations based on the content of the sensing report record collection, generates multiple positioning results respectively based on the multiple positioning combinations, and performs a weighting process to the multiple positioning results to generate a final positioning result of the unauthorized device.
