Object-Connecting Device With Retaining Ring Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional object-connecting devices weaken structural strength when subjected to forces, particularly in the horizontal direction, due to recesses that compromise sleeve integrity and risk breakage, and the bolt may loosen, posing safety hazards.
Innovation Solution
The object-connecting device features an engaging member with a perforation, a first sleeve with a recess and axial hole, a second sleeve with a matching recess and axial hole forming a receiving groove, and a bolt with a retaining ring, which is fastened in the groove to prevent disengagement without compromising structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a retaining ring is disposed in a recess of the sleeve to prevent bolt disengagement, then the bolt is secured from loosening, but the structural strength of the sleeve is compromised
Solution Approach 1:
The device is divided into two sleeves (first sleeve and second sleeve) that work together. The retaining ring is disposed in the second sleeve only, while the first sleeve maintains its full structural integrity. This segmentation allows the retaining function to be isolated to one component without compromising the overall structural strength of the assembly.
Solution Approach 2:
The bolt serves as an intermediary element that connects both sleeves and the retaining ring. By fastening the retaining ring to the bolt, the system achieves bolt retention without requiring a recess in the load-bearing sleeve. The bolt mediates between the retaining ring and the sleeve assembly, transferring forces appropriately.
2Reliability
If the retaining ring is fastened on the bolt, then the bolt is prevented from disengaging from sleeves, but the device complexity increases
Solution Approach 1:
The bolt serves multiple functions: it connects the first and second sleeves together, provides a mounting surface for the retaining ring through its annular groove, and transmits mechanical loads. By making the bolt multi-functional, the design avoids adding separate retaining mechanisms while still achieving reliable bolt retention.
Solution Approach 2:
The retaining ring and the bolt are combined into a single functional unit where the retaining ring is fastened directly to the bolt. This merging eliminates the need for separate retaining mechanisms and simplifies the overall assembly process while maintaining reliability.

AI summary
An object-connecting device includes an engaging member having a perforation, a first sleeve having a first axial hole, a first abutting surface, and a first recess, a second sleeve passing through the perforation, a bolt passing through the first axial hole and the second axial hole, and a retaining ring. The second sleeve has a second axial hole, a second abutting surface, and a second recess, wherein the second axial hole communicates with the first axial hole. The second abutting surface abuts against the first abutting surface. The second recess matches with the first recess to form a receiving groove. The retaining ring is disposed in the receiving groove and is fastened on the bolt. With the aforementioned design, the bolt could be prevented from disengagement.
