Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery is used to power the beacon transmitter, then the beacon can operate independently and be easily installed, but the battery requires frequent replacement leading to high lifecycle costs and service disruptions
Solution Approach 1:
The beacon transmitter is merged with the lighting device to form an integrated unit. The lighting device's power supply system directly powers the beacon transmitter, eliminating the need for a separate battery. This combination ensures continuous operation of the beacon as long as the lighting device is powered, while maintaining easy installation through a single integrated unit.
2Measurement precision
If the beacon transmitter operates continuously to provide accurate localization services, then service accuracy is improved, but energy consumption increases requiring more frequent battery replacement
Solution Approach 1:
The beacon transmitter is pre-configured within the lighting device with access to the lighting device's power supply system. This preliminary arrangement ensures that the beacon can operate continuously without energy constraints, as the power supply is already in place and designed to support continuous operation of the lighting system.
3Ease of operation
If the beacon is installed at floor level for easy access and installation, then installation ease is improved, but the signal propagation is blocked by objects and the system becomes vulnerable to manipulation
Solution Approach 1:
The beacon transmitter is relocated from the floor level to the lighting device which is positioned at ceiling level. This dimensional change in installation location eliminates signal blockage by floor-level objects and protects the beacon from manipulation, while the integrated design maintains installation ease through a single unified component.
4Reliability
If the beacon transmitter is integrated into the lighting device with energy buffer, then continuous operation is ensured, but the energy buffer may be exhaustively discharged during logistics and installation before startup
Solution Approach 1:
The activation mechanism is configured to detect the operational state of the lighting device and only activate the beacon transmitter when the lighting device is actually operational. This preliminary detection prevents the energy buffer from being discharged during logistics and installation phases when the lighting device is not yet powered, while ensuring the beacon operates continuously once the lighting device is running.
Solution Approach 2:
The activation mechanism continuously monitors the operational state of the lighting device and provides feedback control to the beacon transmitter. When the lighting device is operational, the beacon is activated; when the lighting device is off or during installation, the beacon remains inactive. This feedback mechanism prevents unnecessary energy discharge while ensuring continuous operation during actual use.
