Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Bluetooth beacons are used to broadcast signals for location detection, then location detection accuracy is improved, but device complexity increases
Solution Approach 1:
The system divides the indoor environment into multiple zones, each monitored by individual Bluetooth beacons. Each beacon independently broadcasts location information, and the portable device segments the detection process by comparing signals from different beacons to determine location changes. This segmentation approach improves location accuracy without requiring a monolithic complex system.
Solution Approach 2:
The portable device performs self-service by autonomously monitoring Bluetooth signals, comparing detected locations with stored beacon location data, and determining location changes without external intervention. The device automatically transmits location data when changes are detected, reducing the need for complex external monitoring infrastructure.
2Measurement precision
If continuous location monitoring is implemented, then location reporting accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system implements periodic location checks by having the portable device monitor Bluetooth beacons at intervals. The device compares current beacon detections with stored location data only when necessary, and transmits location information periodically or when changes are detected, rather than continuously. This periodic approach maintains location reporting accuracy while significantly reducing energy consumption compared to continuous monitoring.
3Area of stationary object
If multiple Bluetooth beacons are deployed across multiple floors, then location coverage is improved, but system complexity increases
Solution Approach 1:
The system segments the multi-floor environment by deploying independent Bluetooth beacons on each floor and level. Each beacon operates autonomously, broadcasting its specific location information. The portable device handles the complexity by maintaining a stored database of beacon locations and automatically comparing detected beacons against this database to determine location changes, eliminating the need for complex centralized configuration.
Solution Approach 2:
The portable device acts as an intermediary between the distributed Bluetooth beacons and the external computing device. It stores beacon location data locally, performs intermediate processing by comparing detected signals with stored data, and manages communication with external systems. This intermediary role simplifies the overall system architecture by distributing intelligence to the portable device rather than requiring complex centralized control.
