Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electromechanical actuators are directly attached to brake backplates with custom designs, then the actuators can be adapted to specific vehicle configurations, but the production, installation, and maintenance costs increase significantly
Solution Approach 1:
The mounting assembly is divided into separate components: a supporting bracket that attaches to the brake backplate and a separate actuator mounting interface. This segmentation allows the actuator itself to remain standardized while the bracket adapts to different vehicle configurations, reducing actuator production costs while maintaining adaptability.
Solution Approach 2:
A supporting bracket is introduced as an intermediary component between the brake backplate and the electromechanical actuator. This bracket serves as an adapter that provides the necessary mechanical interface and adaptation, allowing standard actuators to be used across different vehicle models without requiring custom-designed actuators for each application.
2Ease of manufacture
If standard electromechanical actuators are used without adaptation mechanisms, then production costs are reduced, but the actuators cannot be properly installed in various vehicle configurations
Solution Approach 1:
The supporting bracket is designed with universal adaptability to accommodate different brake backplate configurations and vehicle types. By creating a multi-functional mounting interface that can adapt to various installations, the system maintains cost-effective use of standard actuators while achieving broad compatibility across different vehicle platforms.
3Reliability
If custom-designed actuators are created for each vehicle model, then perfect fit and reliability are achieved, but installation and maintenance complexity increase
Solution Approach 1:
By separating the adaptation function into a dedicated supporting bracket component, the actuator design itself remains simple and standardized. This segmentation allows for reliable mounting through the specialized bracket while keeping the actuator installation procedure simple and uniform across different vehicle applications, reducing overall installation complexity.
4Device complexity
If electromechanical actuators are directly mounted without intermediate structures, then the mounting structure is simplified, but the actuators cannot be securely locked in position during brake operations
Solution Approach 1:
The supporting bracket acts as an intermediary mounting structure that provides secure attachment points and locking mechanisms between the brake backplate and the actuator. This intermediate structure ensures reliable mechanical connection and prevents disengagement during brake operations while maintaining a relatively simple overall mounting approach.
