Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electromagnetic valve operates continuously to maintain shock absorption performance, then the shock absorption function is improved, but the electromagnetic valve may overheat and cause damage or oil leakage
Solution Approach 1:
The temperature sensing circuit proactively monitors the electromagnetic valve temperature before overheating damage occurs. By detecting temperature changes in advance and triggering protective actions, the system prevents the harmful effect of overheating while maintaining reliable shock absorption performance during normal operation
Solution Approach 2:
The temperature sensing circuit provides real-time feedback on the electromagnetic valve temperature to the control system. This feedback mechanism enables the controller to adjust the electromagnetic valve operation dynamically, stopping or reducing operation when temperature thresholds are approached, thus preventing overheating damage while maintaining optimal shock absorption when conditions permit
2Reliability
If the temperature monitoring is added to prevent electromagnetic valve damage, then the reliability is improved, but the system complexity increases
Solution Approach 1:
The temperature sensing circuit is integrated with the existing electromagnetic valve control circuit, sharing common components such as the controller and power supply. This merging approach adds temperature monitoring functionality while minimizing the increase in overall system complexity and component count
Solution Approach 2:
The control system is designed with multi-functionality, where the existing controller not only manages the electromagnetic valve operation for shock absorption but also processes temperature data from the sensing circuit. This universal approach allows one component to perform multiple functions, reducing the need for additional dedicated hardware and simplifying the overall system structure
