Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual inspection of each lighting device is performed to ensure proper functioning, then reliability of the emergency lighting system is improved, but maintenance time and cost increase
Solution Approach 1:
The lighting devices perform self-diagnosis by automatically detecting their own operational status, battery charge levels, and potential faults. The system retrieves this self-generated information through the gateway and computing device, eliminating the need for manual inspection while maintaining reliability through continuous automated monitoring.
Solution Approach 2:
The system implements continuous feedback loops where lighting devices report their status to the computing device, which then generates analyses and notifications. This feedback mechanism enables real-time monitoring of system health without requiring physical inspection, allowing maintenance personnel to respond to actual system conditions rather than performing routine manual checks.
2Measurement precision
If manual inspection of lighting devices is performed, then detection precision of faults is improved, but device complexity and maintenance cost increase
Solution Approach 1:
A gateway device serves as an intermediary between the lighting devices and the computing device. The gateway collects data from multiple lighting devices and transmits it to the computing device for analysis, simplifying the overall system architecture while enabling comprehensive monitoring without requiring complex manual inspection procedures.
Solution Approach 2:
The patent replaces manual mechanical inspection with automated electronic monitoring. The computing device uses software algorithms to analyze lighting information, detect faults, and generate reports, substituting human expertise with automated digital systems that provide consistent and precise fault detection without increasing physical system complexity.
3Reliability
If comprehensive monitoring of all lighting devices is implemented, then system reliability is improved, but loss of time for maintenance increases
Solution Approach 1:
The monitoring system is segmented into modular components: individual lighting devices, a gateway device, and a computing device. This segmentation allows the system to monitor each device independently through standardized protocols, enabling comprehensive coverage while maintaining ease of operation and reducing maintenance time through automated data collection and analysis.
Solution Approach 2:
The system performs preliminary monitoring and analysis continuously, identifying potential faults before they become critical. The computing device analyzes lighting information in advance and generates notifications about maintenance needs, allowing maintenance personnel to schedule repairs proactively rather than reactively, improving productivity while maintaining reliability.
