Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a reference amount of brake oil fluid is used for braking control, then the brake system can operate with a fixed control parameter, but the brake control performance degrades when the required fluid amount significantly changes compared to the reference amount
Solution Approach 1:
The patent implements dynamic adjustment of the brake oil fluid amount by continuously monitoring the motor position and calculating the required fluid amount based on actual braking conditions. The controller updates the fluid amount in real-time according to the motor's movement, transforming the static reference amount into a dynamic value that adapts to changing vehicle states, thereby resolving the contradiction between control simplicity and performance reliability
Solution Approach 2:
The patent employs feedback mechanisms by monitoring the motor position sensor data and using it to calculate the required brake oil fluid amount. The controller receives feedback about the motor's current position and adjusts the fluid amount accordingly, creating a closed-loop control system that maintains optimal braking performance despite variations in vehicle conditions
2Reliability
If the required fluid amount is continuously monitored and adjusted, then the brake control performance is maintained, but the system complexity and calculation burden increase
Solution Approach 1:
The patent implements self-service by enabling the brake system to automatically monitor its own operating conditions through the motor position sensor and autonomously calculate and adjust the required brake oil fluid amount without external intervention. The controller performs self-diagnosis and self-adjustment based on real-time motor position data, reducing the need for additional complex monitoring systems while maintaining reliable braking control
