Engineering Contradiction Analysis
1Measurement precision
If manual testing verification is used for each emergency lighting device, then testing accuracy can be ensured, but the process becomes costly and time-consuming
Solution Approach 1:
The emergency lighting device performs self-diagnostic testing automatically without requiring manual intervention. The controller executes diagnostic routines that test the battery, charging circuit, and lighting functions, then automatically transmits the results via I/O device. This self-service approach eliminates the need for costly and time-consuming manual verification while maintaining testing accuracy.
Solution Approach 2:
The system implements automatic feedback loops where the controller continuously monitors device status, performs diagnostic tests, and transmits results to a central monitoring system. This automated feedback mechanism ensures testing accuracy is maintained while dramatically reducing the time and cost associated with manual verification processes.
2Reliability
If manual testing verification is performed on each device, then complete testing coverage can be achieved, but the cost and complexity increase
Solution Approach 1:
The controller serves multiple functions: it manages normal lighting operation, executes self-diagnostic tests, stores test results, and communicates with the central monitoring system. This multi-functionality ensures complete testing coverage is achieved without increasing overall system complexity, as the same existing controller handles all tasks.
Solution Approach 2:
The patent combines the testing, data storage, and communication functions into a single integrated system. The controller performs diagnostics, the I/O device handles communication, and results are automatically logged—all merged into one automated process. This integration maintains complete testing coverage while reducing the complexity that would arise from separate manual testing systems.
3Productivity
If automated self-diagnostic tests are implemented, then time and cost are reduced, but system complexity increases
Solution Approach 1:
The system automates the entire testing process through self-service mechanisms. The controller automatically executes diagnostic routines, the I/O device automatically transmits results, and the central system automatically logs data. This automation dramatically improves productivity while the complexity increase is minimal because it leverages existing controller and communication infrastructure rather than adding entirely new systems.
