Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current telematics systems are used without dedicated light failure detection, then device complexity is reduced, but reliability of lighting monitoring deteriorates
Solution Approach 1:
The light failure detection system is nested within the existing telematics system architecture. The voltage monitoring circuits, current monitoring circuits, and microcontroller are integrated as sub-components of the master control unit, allowing the lighting monitoring function to be embedded within the broader telematics infrastructure without requiring a completely separate system.
Solution Approach 2:
The master control unit is designed to perform multiple functions simultaneously: it monitors lighting conditions through voltage and current sensing, tracks vehicle location via GPS, communicates with remote servers, and provides overall system control. This multi-functional approach consolidates what could be separate systems into a single integrated unit, improving reliability without proportionally increasing complexity.
2Reliability
If real-time monitoring of lighting circuits is implemented, then reliability of safety monitoring is improved, but use of energy increases
Solution Approach 1:
The system employs periodic monitoring rather than continuous monitoring of all parameters. The microcontroller cycles through checking voltage levels, current draw, and temperature at predetermined intervals, allowing the lighting circuits to remain in low-power states between measurements while still providing reliable detection when anomalies occur.
Solution Approach 2:
The voltage monitoring circuits and current monitoring circuits automatically detect failures without requiring manual intervention or additional power-intensive processing. The system uses the existing electrical signals from the lighting circuits themselves to detect failures, essentially having the circuits monitor themselves through passive sensing of their own operational parameters.
3Measurement precision
If multiple monitoring circuits (voltage, current, temperature) are added, then measurement precision of lighting conditions is improved, but device complexity increases
Solution Approach 1:
The voltage monitoring circuits, current monitoring circuits, and temperature sensing are merged into a single integrated monitoring architecture under one microcontroller. Rather than having separate independent systems for each parameter, all sensing functions are consolidated within the master control unit, allowing precise multi-parameter monitoring while managing complexity through unified control and processing.
4Ease of operation
If wireless transmission of failure data is implemented, then ease of operation for remote detection is improved, but loss of time for data transmission may occur
Solution Approach 1:
The system performs preliminary local processing and validation of failure data before transmission. The microcontroller immediately detects and records failure conditions, stores critical information locally, and prepares data packets in advance, so that when transmission occurs, the data is ready for immediate sending, minimizing delays caused by processing during transmission windows.
