Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brake torque is controlled only based on pressing force, then the control system remains simple, but braking performance is inadequate because it does not account for temperature and other influencing factors
Solution Approach 1:
The patent implements feedback control by measuring brake temperature with sensors and using this temperature information to adjust brake torque. The control unit receives temperature data from sensors and modifies the brake torque accordingly, creating a closed-loop control system that adapts to changing thermal conditions and improves braking reliability.
Solution Approach 2:
The patent replaces direct mechanical measurement of brake torque with thermal measurement. Instead of using complex mechanical sensors to measure brake torque directly, the system uses temperature sensors to infer brake torque based on the thermal state of the brake components, simplifying the measurement system while improving accuracy.
2Reliability
If temperature sensors and closed-loop control are added to monitor and adjust brake torque, then braking performance and safety are improved, but the device complexity increases
Solution Approach 1:
The control unit receives temperature data from sensors and uses this feedback to continuously adjust brake torque, creating a closed-loop control system that automatically adapts to thermal conditions and maintains optimal braking performance while ensuring safety.
Solution Approach 2:
The brake system performs self-monitoring and self-adjustment through the integrated temperature sensors and control unit. The system automatically detects thermal conditions and adjusts brake torque without requiring external intervention, enabling the system to service itself and maintain optimal performance.
3Force
If brake torque is increased to improve braking effect, then stopping performance improves, but brake temperature increases leading to potential failure or reduced durability
Solution Approach 1:
The patent implements dynamic adjustment of brake torque based on real-time temperature measurements. The control unit continuously monitors brake temperature and adjusts brake torque dynamically, reducing torque when temperature rises to prevent overheating and failure, while maintaining high torque when temperature is acceptable for optimal braking performance.
Solution Approach 2:
The system changes the operating parameters of the brake system by adjusting brake torque based on temperature conditions. When temperature increases, the control unit modifies the brake torque parameter to prevent excessive heating, thereby managing the trade-off between braking force and temperature control.
