Branched Tube Connection Structure for Precise Flexible Tube Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for liquid-feeding systems, such as those connecting syringes to tubes, face challenges in efficiently and stably connecting flexible tubes due to the lack of a secure and efficient mechanism for alignment and attachment, leading to potential misalignment and reduced work efficiency.
Innovation Solution
A connection device with protruding plates and a jig that abuts the edges of the flexible tube to stabilize it during connection, ensuring proper alignment and secure attachment to the tube, enhancing the efficiency of the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional connection device without protruding plates is used, then the device structure is simple, but the alignment precision and connection stability are insufficient
Solution Approach 1:
The protruding plates are provided in advance on the connection device, with their edges positioned at predetermined locations. These edges abut against the flexible tube during connection, preliminarily establishing the correct alignment position before the tube is fully inserted, thereby ensuring precise alignment without complex adjustment mechanisms
Solution Approach 2:
The edges of the protruding plates serve as intermediary elements between the connection device and the flexible tube. These edges physically abut the tube to transmit alignment forces and maintain proper positioning, acting as a mediating structure that ensures accurate alignment while keeping both the connection device and tube relatively simple in design
2Reliability
If a connection device without a jig is used, then the operation is faster, but the connection stability and reliability are reduced
Solution Approach 1:
The jig is designed with predetermined abutment positions that correspond to the edges of the protruding plates. Before the flexible tube is connected, the jig is positioned and the edges abut the tube, preliminarily securing the tube in the correct position. This preliminary action ensures connection stability while maintaining operational efficiency
Solution Approach 2:
The edges of the protruding plates and the jig work together to automatically establish proper alignment and secure the flexible tube during connection. The structure enables self-alignment and self-securing through the abutment mechanism, reducing the need for complex manual adjustment operations while ensuring reliable connection

AI summary
A connection device includes a tube that is branched to two passages from a branch portion and includes a first and second branch tubes provided on one end side as a liquid-feeding destination, a first protruding plate that includes, on another end side, first another end edge provided in a direction orthogonal to an axis line of the first branch tube and that is provided so as to protrude from an outer circumference portion of the tube, and a second protruding plate that is provided so as to face the first protruding plate across the tube and protrude in a diameter direction of the tube and that includes, on the other end side, second another end edge provided so as to be orthogonal to an axis line of the second branch tube.
