Rotating Fluid Line Connector for Leak-Resistant Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid line connections in fixed items experience movement-related failures and fatigue due to improper securing, leading to potential leakage and damage.
Innovation Solution
A connecting apparatus with a connector body, rotation end, and pre-positioning end, secured by rotation and pre-positioning clips, allows for rotational movement while maintaining a stable connection through precise fitting and sealing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fluid lines are rigidly secured to fixed items, then connection stability is improved, but movement-induced fatigue and failure increase
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotation mechanism that allows the fluid line connection to dynamically adapt to movements. The rotation end and rotation clip enable the fluid line to rotate and absorb movement forces, transforming the rigid static connection into a dynamic one that can accommodate displacement without failure.
Solution Approach 2:
The patent segments the connection apparatus into distinct functional components: a connector body, a rotation end with rotation clip, and a pre-positioning end with pre-positioning clip. This segmentation allows each component to perform its specific function - the rotation end handles rotational movement while the pre-positioning end provides stable anchoring, resolving the contradiction between stability and movement accommodation.
2Reliability
If rotation mechanism is added to accommodate movement, then resistance to fatigue is improved, but connection stability may compromise
Solution Approach 1:
The pre-positioning clip and pre-positioning end provide preliminary action by securing the fluid line in place before any rotational movement occurs. This preliminary securing ensures that the connection maintains stability during installation and operation, while the rotation mechanism only engages when movement is needed, thus preserving both stability and fatigue resistance.
Solution Approach 2:
The rotation mechanism acts as an intermediary between the fixed connector body and the movable fluid line. It mediates the conflict between stability and movement by providing a controlled rotation interface that allows movement while maintaining connection integrity, preventing both fatigue failure and disconnection.
3Reliability
If secure attachment mechanism is used to prevent disconnection, then connection reliability is improved, but rotational movement capability is restricted
Solution Approach 1:
The rotation clip and rotation end create a dynamic connection that is secure in the installed position but allows controlled rotation. The design maintains reliability by ensuring the fluid line remains firmly attached during normal operation while enabling rotational movement when needed, thus resolving the contradiction between secure attachment and movement capability.
Solution Approach 2:
The patent changes the parameter of connection rigidity from fixed to variable. The connection is rigid and secure during normal operation to prevent disconnection, but can change to allow rotation when movement is required. This parameter change enables the system to maintain both reliability and adaptability under different operational conditions.

AI summary
A connecting apparatus provides for rotational movement while maintaining a secured connection. The connecting apparatus has a connector. The connector comprises a connector body and one or more rotation ends coupled to the connector body. A rotation fitting is located at least partially inside the connector though each rotation end, and the rotation fitting defines a rotation fitting groove. A rotation clip engages and secures the rotation fitting to the connector by extending inside each rotation end and engaging the rotation fitting groove. The rotating fitting can rotate in relation to the connector.
