Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of the gap between brake lining and brake drum is performed, then the gap can be adjusted, but adjustment uncertainty causes brake drum vibration and accidental contact
Solution Approach 1:
The patent replaces manual mechanical adjustment with an electromagnetic actuator that automatically controls the brake arm position. The actuator receives control signals to precisely adjust the gap between brake lining and brake drum, eliminating manual adjustment uncertainty and preventing brake drum vibration and accidental contact.
Solution Approach 2:
The patent employs sensors to detect the actual gap between brake lining and brake drum, providing feedback signals to the control system. This closed-loop feedback mechanism enables real-time monitoring and automatic adjustment of the gap, ensuring precise positioning and preventing excessive adjustment that would cause vibration or contact.
2Reliability
If workers regularly adjust the gap manually, then the gap can be maintained, but frequent manual intervention increases operation time and labor
Solution Approach 1:
The patent implements a self-adjusting braking system where the electromagnetic actuator automatically maintains the optimal gap between brake lining and brake drum. The system monitors gap conditions through sensors and performs adjustments without human intervention, eliminating the need for workers to regularly manually adjust the gap and freeing up operational time.
Solution Approach 2:
Through continuous sensor monitoring and feedback control, the system automatically detects when gap adjustment is needed and executes corrections without human intervention. This closed-loop control maintains consistent gap conditions over time, eliminating the need for frequent manual checks and adjustments.
3Ease of operation
If the brake arm is lifted by electromagnet, then the brake lining separates from brake drum, but excessive lifting causes uncertainty in gap maintenance
Solution Approach 1:
The patent uses sensors to monitor the position of the brake arm and the gap between brake lining and brake drum during the lifting operation. The control system receives feedback signals and adjusts the electromagnetic actuator output to achieve precise gap control, ensuring that the brake arm is lifted sufficiently to separate the brake lining from the brake drum while maintaining accurate gap positioning.
Solution Approach 2:
The patent implements dynamic control of the electromagnetic actuator during the brake release operation. The system adjusts the lifting force and position in real-time based on feedback signals, transitioning smoothly from the braking state to the released state while maintaining precise gap control throughout the process.
