Fitting Assembly Movable Connector Block Pivot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable connectors become non-swingable when a counterpart connector is connected, leading to potential damage due to displacement from vibrations, as the floating support locks and fails to follow the connector's movement.
Innovation Solution
A fitting assembly with a movable connector block supported by a base and a floating support, featuring a protrusion that allows the connector block to pivot about a tip end, maintaining swingability even when a connector is coupled, using a combination of movable pins and elastic members to absorb displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the floating support uses movable pins pressed into cylindrical bodies to enable initial swinging, then the connector can be inserted and connected, but the floating support locks and the movable connector becomes non-swingable
Solution Approach 1:
The floating support is divided into two distinct functional components: movable pins for initial connection and a protrusion for maintaining swingability. This segmentation allows each component to perform its specific function without interfering with the other, resolving the contradiction between connection stability and continued swingability.
Solution Approach 2:
The protrusion acts as an intermediary element between the movable connector and the base. It provides a new pivot point that mediates the swinging motion after connection, allowing the connector to maintain adaptability while the movable pins provide connection stability.
2Reliability
If the movable connector is fixed relative to the base after connection, then connection stability is improved, but the connector cannot follow displacement from vibration or misalignment
Solution Approach 1:
The system transitions from a static fixed connection to a dynamic connection that can adapt. The protrusion enables the movable connector to swing and follow displacement caused by vibration or misalignment, while the movable pins maintain connection stability. This dynamic capability allows the system to respond to harmful vibrations without damage.
3Adaptability or versatility
If the floating support is designed to allow continuous swinging, then adaptability is improved, but the connection stability and positioning accuracy deteriorate
Solution Approach 1:
The floating support structure is segmented into movable pins for positioning and a protrusion for swinging. This segmentation allows the system to achieve both positioning accuracy (through the movable pins) and swingability (through the protrusion) simultaneously, resolving the contradiction between stability and adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The assembly ensures the movable connector remains swingable and follows the connected counterpart's displacement, reducing the risk of damage and improving connection accuracy, thereby enhancing the reliability and stability of fluid and electrical connections.
Implementation Method 1
a coil spring provided inside the cylindrical body and configured to bring the movable pin into pressure contact with the base by biasing the movable pin
Implementation Method 2
the protrusion including a tip end that, when the connector is coupled to the connector coupler, comes into contact, in a connecting direction to the connector, with the other one of the movable connector block and the base, and swingably supports the movable connector block pivotally about the tip end
