Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fluidic brake system is used, then the system structure is simple and easy to manufacture, but the system cannot realize deceleration actuator blending between different types of actuators
Solution Approach 1:
A signal conversion device is introduced as an intermediary between the fluidic brake system and electric deceleration actuators. This device converts fluidic control signals into electric signals, enabling the conventional fluidic system to control multiple types of deceleration actuators (electric machines, retarders, brake units) without requiring complete system replacement, thus achieving actuator blending while maintaining relative system simplicity
Solution Approach 2:
The fluidic brake system is enhanced with multi-functionality by adding the signal conversion device, allowing a single fluidic input to control multiple different types of deceleration actuators. This enables the system to perform both traditional fluidic brake functions and electrically-controlled deceleration functions, achieving versatility without complete system redesign
2Adaptability or versatility
If the complete deceleration system is changed from conventional to electro-fluidic system, then deceleration actuator blending can be realized, but the system complexity and cost increase significantly
Solution Approach 1:
The signal conversion function is extracted as a separate, standalone device rather than integrating it into the entire deceleration system. This allows the conventional fluidic brake system to remain unchanged while adding only the necessary conversion capability, reducing manufacturing complexity and cost compared to converting the entire system to electro-fluidic
Solution Approach 2:
The control system is segmented into independent functional modules: the existing fluidic brake system, the new signal conversion device, and the electric deceleration actuators. This modular approach allows incremental implementation and maintains ease of manufacture by preserving the original fluidic system while adding selective electronic control capabilities
