Rotatable Pipe Connecting Assembly for Angular Coupling Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting assemblies for pipes do not allow for easy rotation of fittings after initial securing, limiting the ability to couple them to pipes at different longitudinal angles.
Innovation Solution
A connecting assembly featuring a connecting fitting with a tubular coupling portion and an arcuate-shaped body that can be rotated within a central aperture of a manifold member, allowing for angular adjustment and secure coupling to another tubular wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fitting is secured to a first pipe, then the fitting is firmly attached and stable, but the fitting cannot be readily rotated for coupling to another pipe at a different longitudinal angle
Solution Approach 1:
The connecting assembly is divided into a first connecting portion that couples to the first tubular wall and a second connecting portion that couples to the second tubular wall. These portions can be positioned at different longitudinal angles relative to each other, allowing the fitting to be firmly attached to one pipe while maintaining the ability to couple to another pipe at a different angle through the segmented structure.
2Reliability
If a fitting is secured to a first pipe, then the fitting is firmly attached and stable, but the fitting cannot be readily rotated for coupling to another pipe at a different longitudinal angle
Solution Approach 1:
The connecting assembly incorporates a rotating mechanism that allows the second connecting portion to rotate relative to the first connecting portion. This dynamic capability enables the fitting to adapt to different longitudinal angles while maintaining firm attachment to the first pipe, thereby improving versatility without compromising reliability.
3Reliability
If a fitting is designed for firm attachment to pipes, then connection stability is improved, but the complexity of the fitting structure increases, preventing easy rotation
Solution Approach 1:
The connecting assembly features a nested structure where the second connecting portion is positioned within or alongside the first connecting portion. This nesting allows the rotating mechanism to be integrated into the overall fitting structure without significantly increasing external complexity, enabling easy rotation while maintaining connection stability.

AI summary
A connecting assembly that can be coupled to a tubular wall is provided. The assembly includes a connecting fitting having a tubular coupling portion, an abutment ring, and an arcuate-shaped tubular body. The abutment ring is disposed around an outer surface of the tubular coupling portion a predetermined distance from a first end of the tubular coupling portion. An end of the tubular body is coupled to a second end of the tubular coupling portion. The assembly further includes a retaining member having a ring-shaped portion and first and second finger portions extending from the ring-shaped portion. The arcuate-shaped tubular body of the connecting fitting is received through a central aperture of the ring-shaped portion such that the ring-shaped portion is slidably disposed on the tubular body of the connecting fitting and is further slidably disposed against the abutment ring.
