Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded connection is used to connect connecting sleeve and connecting cylinder, then static tightness and reliability are improved, but assembly complexity increases and dynamic stability deteriorates
Solution Approach 1:
The patent divides the inner housing into two separate halves (first inner housing half and second inner housing half) that can be independently assembled. This segmentation eliminates the need for complex threaded connections while maintaining structural integrity, as the two halves simply fit together to form the complete inner housing that contains the core assembly.
Solution Approach 2:
Instead of using threaded connections to achieve tightness, the patent inverts the approach by using a snap-fit or friction-fit mechanism where the connecting sleeve directly engages with the connecting cylinder through complementary geometric features. This reversal of the connection method simplifies assembly while maintaining reliability.
2Strength
If integral inner housing structure is used, then structural strength is improved, but assembly simplicity deteriorates and dynamic stability is reduced
Solution Approach 1:
The inner housing is segmented into two halves that can be assembled separately around the core, making assembly simpler while maintaining structural strength through the combined geometry of the two halves. This segmentation allows for easier installation without requiring complete disassembly and reassembly of an integral structure.
Solution Approach 2:
The core assembly (including core, connecting cylinder, and spring) is nested within the inner housing formed by the two halves. This nesting arrangement maintains structural integrity while simplifying assembly, as the core assembly can be pre-formed and then inserted into the housing rather than being constructed in place.
3Ease of operation
If spring is completely inserted from opening end for assembly, then assembly is simplified, but positioning accuracy deteriorates and dynamic stability is reduced
Solution Approach 1:
The spring is pre-compressed or pre-positioned within the connecting cylinder before final assembly into the inner housing. This preliminary action ensures proper positioning and orientation of the spring, improving positioning accuracy while maintaining assembly simplicity through the standardized insertion process from the opening end.
Solution Approach 2:
The connecting cylinder serves as an intermediary structure that holds and positions the spring during assembly. This intermediary component provides precise geometric features (such as grooves or shoulders) that ensure accurate spring positioning, while the spring itself can still be easily inserted from the opening end without complex positioning requirements.

AI summary
Provided herein is an SC connector with a stable structure and an easy assembly. The SC connector has the characteristics of compact assembly, and the assembly mode of its inner core structure is more conducive to the integration after assembly. Especially after adhesive injection, as the mold closing seam of the inner core structure is not a split structure in the general sense, it is not easy to be separated and broken due to external force action, achieving better stability than existing general products. It can effectively prolong the service life of equipment in low-frequency vibration environment. As a pre-assembled connector with good performance, it can be easily assembled and reliable when used on-site, and can be quickly applied to line assemblies.
