Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate air filters and resonators are provided for each component, then noise reduction and air filtration performance are improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple air filtration outlets into a single integrated air filter housing that serves multiple components (engine, brake compressor, etc.). This merging approach reduces the number of separate filters and resonators needed, thereby reducing noise while decreasing device complexity and space requirements simultaneously
2Reliability
If separate air filters are provided for all components, then air filtration performance is improved, but space usage efficiency deteriorates
Solution Approach 1:
The air filter housing is designed as a universal multi-functional unit that provides filtered air to multiple components through a single structure. This allows the system to maintain reliable air filtration for the engine, brake compressor, and other auxiliary equipment while occupying significantly less space than multiple separate filters would require
3Object-affected harmful factors
If complex air filter systems are used, then noise reduction is improved, but assembly time increases
Solution Approach 1:
By merging noise reduction resonators and air filtration functions into a single integrated housing unit, the system reduces the number of separate components that need to be assembled. This maintains effective noise reduction while significantly reducing assembly time compared to complex systems with multiple separate filters and resonators
