Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beacons continuously transmit beacon signals for indoor positioning, then positioning accuracy is improved, but power consumption increases and device service life decreases
Solution Approach 1:
The patent implements periodic action by controlling beacons to transmit beacon signals only at specific time points when task-related personnel enter the vicinity, rather than continuous transmission. The system determines transmission timing based on task information and real-time location data, creating an on-demand periodic transmission pattern that reduces power consumption while maintaining positioning accuracy when needed.
Solution Approach 2:
The system performs preliminary action by pre-determining task information including location data and required personnel before execution. When personnel approach the beacon area, the system has already prepared the transmission schedule, enabling immediate accurate positioning without requiring continuous signal emission, thus reducing overall power consumption.
2Reliability
If beacons continuously transmit beacon signals, then positioning function is always available, but battery replacement frequency increases
Solution Approach 1:
By implementing periodic transmission only when task-related personnel are present in the beacon area, the system maintains positioning reliability during task execution while significantly extending battery service life through reduced transmission duty cycle.
Solution Approach 2:
The system uses task management information and automatic location tracking to self-determine when beacon transmission is necessary, eliminating the need for continuous operation. The beacon device automatically activates transmission only when task-related personnel enter the vicinity, extending service life without compromising task-related positioning availability.
3Area of stationary object
If all beacons in the area transmit signals continuously, then positioning coverage is comprehensive, but energy consumption and maintenance costs increase
Solution Approach 1:
The patent applies local quality by enabling beacon transmission only in specific local areas where task-related personnel are present, rather than uniform continuous transmission across the entire beacon area. The system selectively activates beacons based on task information and real-time location data, achieving comprehensive coverage when needed while minimizing overall energy consumption.
Solution Approach 2:
The system implements periodic activation of beacons based on task requirements and personnel location, creating an on-demand transmission pattern that maintains comprehensive positioning coverage during task execution while significantly reducing total energy consumption compared to continuous transmission.
