Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional quick connectors are designed to match specific plug types, then sealing performance is ensured for that specific plug, but adaptability to different plug sizes deteriorates
Solution Approach 1:
The quick connector is designed with a universal structure that can accommodate multiple plug types (no. 3, no. 5, no. 6, no. 17, and no. 19 American standard plugs). The connector hub features ball grooves that can adapt to different plug diameters, and the connector valve core with its hollow structure and open front end can seal against various plug sizes, allowing one connector to serve multiple functions across different pipeline sizes.
Solution Approach 2:
The connector employs localized sealing features including sealing rings positioned at specific locations within the connector valve core and ball grooves with varying depths and positions. These localized structural variations enable the connector to maintain reliable sealing contact with different plug types while preserving the overall universal design.
2Reliability
If quick connectors and plugs are replaced to match different pipeline sizes, then proper connection is achieved, but operation complexity increases
Solution Approach 1:
The quick connector is designed as a universal interface that eliminates the need to replace connectors or plugs when working with different pipeline sizes. Operators can connect any of the five American standard plug types to this single connector design, significantly simplifying operations and reducing the complexity of inventory management while maintaining reliable airtight connections.
3Adaptability or versatility
If multiple sealing rings with different inner diameters are arranged in the connector valve core, then adaptability to various plug sizes is improved, but device complexity increases
Solution Approach 1:
The connector valve core incorporates multiple sealing rings with progressively different inner diameters positioned at specific locations. Each sealing ring targets a specific range of plug sizes, creating localized adaptation zones within the single connector. This approach enables versatile compatibility across five different plug types while maintaining a relatively simple overall structure that can be manufactured as a single integrated component.
