Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless beacons are installed for indoor localization, then localization accuracy is improved, but installation cost and complexity increase
Solution Approach 1:
The patent applies multi-functionality by enabling fire safety devices to serve dual purposes: both fire detection and indoor localization. The beacon transmitter is integrated into existing fire safety equipment, allowing it to perform its original fire safety function while simultaneously providing localization services through wireless signal transmission. This eliminates the need for separate dedicated beacons, reducing installation complexity and cost.
Solution Approach 2:
The patent merges the beacon transmitter functionality with fire safety devices by integrating the wireless transmission component into the fire alarm system. The beacon transmitter is combined with the fire detection and notification devices, creating an integrated system where a single component serves multiple functions - fire safety monitoring and indoor positioning. This consolidation reduces the number of separate installations required.

This eliminates the need for separate dedicated beacons, reducing installation complexity and cost.
Solution Approach 2:
The system utilizes existing fire safety infrastructure to provide localization services without requiring separate dedicated beacons. The fire safety devices serve themselves by incorporating the beacon transmitter functionality, allowing the same hardware to perform both fire monitoring and positioning tasks. This self-service approach eliminates the need for additional separate installations and reduces overall system cost.
3Reliability
If beacon transmitters are powered continuously, then localization availability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by having the beacon transmitter operate in intermittent cycles rather than continuously. The transmitter activates during specific periods when localization is needed and remains inactive during other periods, thereby reducing overall power consumption while maintaining localization availability when required. This periodic operation pattern allows the system to balance reliability with energy efficiency.
Solution Approach 2:
The system dynamically adjusts the power consumption of the beacon transmitter based on operational needs. The transmitter can transition between active and inactive states, and the power management circuit adapts the transmission schedule according to the building's requirements. This dynamic power management allows the system to maintain localization availability during critical periods while minimizing power consumption during non-critical periods.
