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 connector is divided into separate components (connecting sleeve, connecting cylinder, inner housing) that can be assembled through simple insertion rather than threaded connection. The segmentation allows each part to maintain its structural integrity while enabling straightforward assembly by eliminating the need for threading operations.
Solution Approach 2:
Instead of using threaded connection to achieve tightness, the patent inverts the approach by using a press-fit or interference fit mechanism where the connecting cylinder is inserted into the connecting sleeve with tight tolerance配合, achieving static tightness through precise dimensional control rather than mechanical threading.
2Reliability
If threaded connection is used to connect connecting sleeve and connecting cylinder, then reliability is improved, but assembly time increases
Solution Approach 1:
The connecting cylinder is pre-assembled with the inner housing assembly before insertion into the connecting sleeve. This preliminary assembly ensures proper positioning and alignment, allowing for quick final assembly without time-consuming threading operations while maintaining connection reliability.
3Ease of operation
If spring is completely inserted from opening end of inner housing for assembly, then assembly is simplified, but dynamic stability deteriorates due to circumferential force on threaded connection
Solution Approach 1:
The spring is extracted from the threaded connection system and repositioned to bear only axially against the connecting cylinder's end face. This removes the source of circumferential force that compromised dynamic stability, while the spring's assembly simplicity is maintained through the open-ended insertion method.
Solution Approach 2:
The connecting cylinder serves as an intermediary element that receives the spring's axial force and transmits it to the connecting sleeve through direct contact, eliminating the need for threaded connection to transmit the spring force and thereby improving dynamic stability.

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.
