Tubular Connection Structure Anti-Loosening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tubular connector designs lack effective mechanisms to prevent loosening due to vibrations or external forces, leading to potential leakage and contamination.
Innovation Solution
A tubular connection structure incorporating a clasp lever and stirring lever with a reset component, stop convex portion, and guiding surface, along with fixing members, to securely fasten tubes and prevent loosening, utilizing a ring for user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a prior tubular connector uses only a convex portion of the fastening handle for connection, then the structure is simple, but the connector can be easily loosened by vibrations or external forces
Solution Approach 1:
The fastening mechanism is divided into two independent levers: a clasp lever for initial connection and a stirring lever for locking. This segmentation allows each lever to specialize in one function, with the clasp lever providing simple connection and the stirring lever providing secure locking against loosening.
Solution Approach 2:
The stirring lever acts as an intermediary locking mechanism between the clasp lever and the connector body. It mediates the connection by providing an additional security layer that prevents the clasp lever from loosening due to vibrations or external forces.
2Reliability
If a tubular connector adds a security device to prevent loosening, then the anti-loosening capability is improved, but the device complexity increases
Solution Approach 1:
Both the clasp lever and stirring lever are designed as pivotal (rotating) components that can move dynamically. The stirring lever rotates to engage or disengage the stop convex portion with the stop recess, providing a dynamic locking mechanism that is more reliable than static connections.
Solution Approach 2:
The stirring lever mechanism is designed to be self-locking through the interaction between the stop convex portion and stop recess. Once the stirring lever is rotated into the locked position, the geometry of these features automatically maintains the locked state without requiring additional active components or continuous energy input.
3Reliability
If a tubular connector uses a complex fastening mechanism with multiple levers, then the anti-loosening capability is improved, but the ease of operation decreases
Solution Approach 1:
The stirring lever is extracted as a separate, dedicated component with a prominent ring handle that can be easily grasped and rotated. This extraction allows the locking action to be performed with a simple rotational motion of the stirring lever, independent of the clasp lever operation.
Solution Approach 2:
The clasp lever performs the preliminary action of bringing the two connectors together and establishing the basic connection. Only after this preliminary connection is made does the stirring lever need to be operated for the final locking action, dividing the operation into two simple sequential steps.
