Pipe Connecting Joint With Positioning Groove To Prevent Tube Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chemical transportation pipeline structures face issues due to direct contact between inner and outer tubes, leading to friction, vibration, noise, and increased risk of leakage, especially when the inner tube is damaged, causing environmental hazards and costly replacements.
Innovation Solution
A pipe connecting joint with a connecting member featuring sleeves, covers, and limiting pipes, which includes positioning grooves and semicircular pipes to prevent contact between inner and outer tubes, using adhesive layers and sealing washers for secure engagement and isolation, allowing for segmented connections and centralized fluid management in case of leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the inner tube is directly pierced through the inside of the outer tube, then the structure is simple and easy to manufacture, but the inner tube contacts the outer tube causing friction, vibration, noise, and increased leakage risk
Solution Approach 1:
A positioning groove is introduced as an intermediary structure between the inner tube and outer tube. The positioning groove extends along the outer tube and receives the inner tube, providing guided support while preventing direct contact and friction between the tubes. This mediator structure resolves the contradiction by maintaining structural simplicity while eliminating the harmful contact that causes leakage.
2Length of moving object
If the inner tube is long, then the transportation pipeline can cover longer distance, but the inner tube gravity causes contact with outer tube leading to friction and damage
Solution Approach 1:
The positioning groove acts as a mediator that supports the weight of long inner tubes while preventing contact with the outer tube. By providing a dedicated receptacle structure along the outer tube, the inner tube's gravity is managed without causing friction or damage to either tube, enabling longer pipeline sections without compromising durability.
Solution Approach 2:
The positioning groove introduces a new spatial dimension for support - rather than relying solely on end supports, the groove provides continuous lateral support along the length of the inner tube. This dimensional addition allows long tubes to maintain their length advantage while distributing gravitational loads to prevent contact-induced damage.
3Productivity
If fluid flows through the inner tube, then transportation function is achieved, but fluid pressure causes vibration and rocking resulting in continuous friction with outer tube
Solution Approach 1:
The positioning groove serves as a mediator that decouples the inner tube from the outer tube, allowing fluid-induced vibrations to occur within the groove without transmitting friction forces to the outer tube. This intermediary structure enables continuous fluid transportation while isolating the harmful vibration and noise effects.

AI summary
A pipe connecting joint has: a connecting member and two limiting pipes. The connecting member has the two sleeves and the two covers. The sleeve has at least a positioning groove at an inner wall surface, and at both ends of each sleeve is formed with an opening. Furthermore, each sleeve is opened with a window covered by the cover. The two limiting pipe are formed with a semicircular pipe and a disc, and the limiting pipe is placed into the sleeve through the window. The disc abuts against the inner wall surface of sleeve and engages with the position groove.
