Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple emergency devices perform automatic testing simultaneously in the same area, then testing coverage is improved, but battery exhaustion risk increases and system reliability deteriorates
Solution Approach 1:
Devices exchange testing status information through wireless communication, allowing each device to receive feedback about whether neighboring devices are currently testing. This feedback mechanism enables dynamic adjustment of testing schedules to avoid simultaneous testing events in the same area.
Solution Approach 2:
The system performs preliminary checks of neighboring devices' testing status before initiating a test. By checking whether other devices are already testing or have recently tested, the system can preliminarily determine the appropriate timing for its own test, preventing battery exhaustion from simultaneous testing.
2Reliability
If emergency devices communicate only with a base station, then system architecture is simplified, but communication reliability and system performance deteriorate during power outages
Solution Approach 1:
The communication architecture is segmented into multiple independent communication paths: device-to-base station communication and device-to-device communication. This segmentation allows the system to maintain communication functionality even when base station communication is unavailable during power outages.
Solution Approach 2:
The wireless communication unit serves multiple functions: it enables both traditional base station communication and direct device-to-device communication. This multi-functionality allows the system to adapt to different operational scenarios, maintaining reliability whether communicating with a base station or directly with neighboring devices during emergencies.
3Productivity
If no device-to-device communication is implemented, then device complexity is reduced, but testing coordination and system readiness efficiency deteriorate
Solution Approach 1:
Devices autonomously coordinate their testing schedules by exchanging status information with neighboring devices. Each device independently determines its own testing timing based on received information from neighbors, eliminating the need for centralized coordination and improving testing coordination efficiency.
