Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional security measures are used in multi-room environments, then device complexity is reduced, but measurement precision of employee location is insufficient
Solution Approach 1:
The system divides the monitoring area into multiple zones with gateway devices strategically positioned in each zone. Each gateway independently monitors its local area using beacon signals, and the server aggregates data from multiple gateways to achieve precise location determination across the entire multi-room environment.
Solution Approach 2:
Gateway devices serve as intermediaries between personal locator devices worn by employees and the central server. The gateways receive beacon signals from locators, perform initial processing and triangulation calculations, then transmit processed location data to the server, reducing the computational burden on the central system while improving location precision.
2Measurement precision
If a vertical and horizontal array of gateway devices is deployed, then location determination accuracy is improved, but device complexity increases
Solution Approach 1:
Each gateway device in the vertical and horizontal array is designed with multi-functionality, serving as a wireless access point, a beacon signal receiver, a local triangulation processor, and a data transmitter. This universal design allows the system to achieve high location precision through multiple gateways without proportionally increasing overall system complexity.
3Measurement precision
If signal strength modeling and trilateration are used, then location precision is improved, but use of energy increases
Solution Approach 1:
The system performs signal strength modeling and trilateration calculations only when necessary for location determination, rather than continuously. Gateway devices process beacon signals event-driven, performing complex computations only when new locators enter the monitoring area or when location updates are required, reducing overall energy consumption while maintaining high location precision.
