Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple discrete oil return lines are used for each separating module, then oil return functionality is provided, but device complexity and connection complexity increase
Solution Approach 1:
The patent combines multiple discrete oil return lines into a single common oil return line that serves multiple separating modules. This merging approach reduces the number of connections required while maintaining oil return functionality for all modules, thereby decreasing device complexity and connection complexity without compromising reliability
Solution Approach 2:
The common oil return line serves as a universal connection that handles oil return for multiple separating modules simultaneously. This multi-functional design allows a single line to perform the oil return function for several modules, reducing the overall number of components and connections needed in the system
2Reliability
If existing crankcase ventilation systems are designed with multiple discrete components, then separation functionality is provided, but compactness and adaptability are reduced
Solution Approach 1:
The patent divides the crankcase ventilation system into modular separating modules that can be independently configured and combined. Each module maintains full separation functionality, while the modular structure allows flexible adaptation to different operating conditions and engine types, achieving both reliability and adaptability
Solution Approach 2:
The system is designed with dynamic adaptability through its modular architecture, allowing the number and configuration of separating modules to be adjusted based on varying operating conditions. This dynamic design enables the system to optimize performance across different scenarios while maintaining compact integration
3Reliability
If existing systems require complex connections for multiple components, then separation functionality is achieved, but ease of assembly and compactness are worsened
Solution Approach 1:
The patent merges multiple connection functions into integrated housing openings that provide direct access to parallel channels. This consolidation reduces the number of separate connections required during assembly, making the system easier to install while maintaining reliable separation functionality through the integrated channel structure
