Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed location beacons are used for location monitoring, then location tracking capability is provided, but the integrity and reliability of location information is compromised
Solution Approach 1:
The patent introduces an intermediary verification system that acts as a mediator between the beacon and the monitoring system. This intermediary layer validates beacon authenticity through multiple independent verification methods (altitude verification, motion detection verification, power loss detection verification) before accepting location data, thereby improving reliability without requiring fundamental changes to the beacon hardware itself.
Solution Approach 2:
The verification process is segmented into multiple independent verification modules: altitude verification, motion detection verification, and power loss detection verification. Each module independently checks a specific aspect of beacon integrity, and all must pass for the location data to be accepted. This segmentation allows comprehensive verification while maintaining modular system architecture.
2Reliability
If altitude sensing beacons with multiple detection circuits are implemented, then reliability of location data is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple verification functions (altitude sensing, motion detection, power loss detection) into a single integrated beacon device. These previously separate functions are merged into one unit that performs all verifications internally, reducing the need for separate external verification devices and simplifying the overall system architecture while maintaining high reliability.
Solution Approach 2:
The beacon device is designed with multi-functionality, serving both as a location marker and as a self-verifying authentication device. The same beacon that provides location information also contains the altitude sensor, motion detector, and power loss detector, allowing it to perform multiple functions simultaneously and reducing the need for separate specialized devices.
3Measurement precision
If alert levels are generated based on multiple parameters, then detection accuracy of beacon compromise is improved, but processing complexity increases
Solution Approach 1:
The system performs preliminary verification actions by continuously monitoring altitude, motion, and power status parameters and comparing them against expected values before processing location data. This preliminary action filters out compromised beacons early in the process, preventing complex analysis of obviously invalid data and reducing the overall processing burden on the monitoring system.
