Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a distributed architecture with separate pressure control modules for each axle is used, then the system can be modular and easier to manufacture, but the number of components and connections increases leading to higher defect probability
Solution Approach 1:
The patent combines multiple pressure control modules into a single integrated central pressure control module that controls brake pressure for multiple axles. This merging reduces the total number of components and connections in the brake system, thereby reducing defect probability while maintaining modular design benefits through internal functional separation of different axle control circuits
2Adaptability or versatility
If multiple separate pressure control modules are used for different axles, then each module can be optimized for specific axle requirements, but the overall system requires more connectors and lines
Solution Approach 1:
The patent merges multiple axle-specific pressure control functions into a single central pressure control module with internal circuit separation. Each axle's brake pressure control is handled by dedicated internal circuits within the unified module, maintaining axle-specific optimization capabilities while eliminating the need for multiple external connectors and reducing overall connection complexity
