Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If Helmholtz resonator is used for sound absorption control, then noise reduction effect is improved, but device complexity increases due to complicated structural design and mounting structure
Solution Approach 1:
The sound absorption system is segmented into independent functional components: the wheel hub, the resonator chamber, and the band fastening system. This allows each component to be optimized separately and assembled together, reducing overall structural complexity while maintaining noise reduction effectiveness.
Solution Approach 2:
The resonator chamber is extracted as a separate functional element from the wheel hub structure. By positioning it within the air chamber space and fastening it with a band, the design eliminates the need for complex integrated mounting structures while achieving the same sound absorption function.
2Ease of manufacture
If thin flange and groove engagement mechanism is used to fix resonator component, then manufacturing complexity is reduced, but connection strength deteriorates
Solution Approach 1:
The positioning and fastening functions are merged into a unified band fastening system that simultaneously provides both mechanical strength and ease of installation. The band wraps around the wheel hub and resonator chamber, creating a strong connection without requiring complex thin-walled engagement features.
3Manufacturing precision
If dimensional accuracy dependency is used for component connection, then manufacturing precision requirements are reduced, but installation time increases due to alignment requirements
Solution Approach 1:
The band fastening system applies localized compression and friction at specific contact points between the wheel hub, resonator chamber, and band itself. This localized interaction provides self-alignment during installation, eliminating the need for precise dimensional matching across entire component surfaces while reducing installation time.
4Adaptability or versatility
If separate component assembly is used for resonator and wheel hub, then adaptability is improved, but ease of operation deteriorates due to time-consuming alignment installation
Solution Approach 1:
The band fastening system introduces dynamic adjustability to the assembly process. The band can be easily tightened or loosened during installation and maintenance, allowing for quick alignment and secure fastening without permanent or irreversible operations. This dynamic mechanism greatly improves ease of operation while maintaining component adaptability.
