Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual observation-based alert systems are used to detect malfunctions, then the system complexity remains low, but the detection time is delayed and repair costs increase
Solution Approach 1:
A wireless communication system acts as an intermediary between the vehicle's control systems and off-board electronic devices. The system includes a wireless communication interface that receives status information from vehicle subsystems and transmits it to remote devices, enabling early malfunction detection without requiring complex on-board diagnostic infrastructure.
Solution Approach 2:
The system establishes a feedback loop where status information about vehicle parameters is continuously monitored, compared against threshold values, and automatically transmitted when breaches occur. This closed-loop feedback mechanism enables timely detection and notification of malfunctions while maintaining simple system architecture.
2Loss of time
If wireless communication systems are added to enable remote monitoring, then malfunction detection is improved, but the device complexity increases
Solution Approach 1:
The system extracts only the essential status information about vehicle parameters that are critical for malfunction detection. Rather than transmitting all possible data, the wireless communication system selectively transmits only those parameters that breach predefined thresholds, minimizing communication overhead and system complexity while reducing downtime through targeted monitoring.
Solution Approach 2:
The control system is designed to handle multiple vehicle subsystems through a unified wireless communication interface. The same communication infrastructure serves multiple functions including status monitoring, threshold comparison, and remote notification, thereby reducing overall system complexity while enabling comprehensive remote monitoring to minimize downtime.
3Measurement precision
If continuous monitoring of all vehicle parameters is implemented, then detection accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system employs periodic sampling of vehicle parameters combined with event-triggered transmission. Status information is monitored continuously but transmitted only when parameter values breach predefined thresholds, achieving high measurement precision for critical parameters while minimizing energy consumption by activating communication only when necessary.
Solution Approach 2:
The system changes the monitoring strategy from uniform continuous monitoring to selective threshold-based monitoring. By defining critical threshold values for different parameters and only triggering communication when these thresholds are breached, the system achieves high detection accuracy for critical conditions while significantly reducing overall energy consumption compared to continuous transmission.
