Floating Pipe Joint Assembly for Blind Connection Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In water cooling systems, manufacturing and assembly tolerances lead to axis deviations between male and female pipe joints, causing unreliable connections and potential water leakage during blind connection operations.
Innovation Solution
A fluid pipeline connection device comprising a fixed base, a floating piece, a connecting tube, and elastic bodies, along with a guiding piece and guiding column, which allows for alignment and secure connection of the connecting tube with a receiving tube, even with dimensional deviations, using a protection shell and self-sealing quick pipe joints for reliable sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blind connection of male and female pipe joints is performed, then connection operation can be simplified, but axis deviation due to manufacturing and assembly tolerances causes connection failure or water leakage
Solution Approach 1:
The connecting tube is designed to be movable relative to the fixed base through elastic bodies, allowing dynamic adjustment to compensate for axis deviation during blind connection, while maintaining reliable sealing under pressure
Solution Approach 2:
Elastic bodies are introduced as intermediary elements between the connecting tube and fixed base, serving as a mediator that absorbs positional deviations and enables reliable connection despite manufacturing tolerances
2Device complexity
If male and female pipe joints are directly combined, then assembly process is simplified, but manufacturing and assembly tolerances cause axis deviation and connection failure
Solution Approach 1:
The connecting tube's position parameter is made variable through elastic suspension, allowing automatic adjustment to achieve axis alignment despite manufacturing tolerances in the fixed base and connecting tube
Solution Approach 2:
The rigid fixed connection is transformed into a dynamic system where the connecting tube can move and self-align using elastic bodies, converting manufacturing precision requirements into a tolerance-compensating mechanical system
3Stability of the object's composition
If the connecting tube is fixed in position, then structural stability is improved, but inability to compensate for axis deviation causes connection failure
Solution Approach 1:
The system transitions from a completely fixed structure to a semi-fixed structure where the connecting tube is elastically suspended, providing both stability through the fixed base and adaptability through elastic displacement capability
Solution Approach 2:
The position parameter of the connecting tube is changed from fixed to variable within elastic limits, enabling the system to maintain structural stability while adapting to axis deviations during connection

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures reliable and leak-proof connections by allowing displacement and alignment of the connecting tube within the fluid pipeline connection device, effectively resisting pressure from cooling fluids and maintaining a secure joint despite manufacturing and assembly tolerances.
Implementation Method 1
a plurality of elastic bodies (150). The elastic bodies (150) are disposed in the fixed base (130), and the elastic bodies (150) are in contact with the connecting tube (143)... Pressure of cooling fluids generate a thrust force at a connection between the male and female pipe joints, to separate the male and female pipe joints
