Pipe Joint Clamp-Holding Structure for Leak-Safe Hose Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe joints with hose clamps often result in fluid leaks and require precise, time-consuming attachment and detachment processes, leading to increased maintenance and replacement costs, especially when the hose clamp is attached obliquely.
Innovation Solution
A pipe joint design featuring a nipple with a hose clamp holding portion that maintains the hose clamp in a diametrically expanded state, using a cover member with a guide and release portion to facilitate secure attachment and detachment without pre-attaching the hose clamp to the pipe, preventing damage and loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the hose clamp is attached obliquely to the pipe and nipple, then the attachment process is simpler and faster, but fluid leaks occur from the connecting portion
Solution Approach 1:
The hose clamp holding portion acts as an intermediary structure that guides the hose clamp into the correct position. It includes a guide surface that directs the hose clamp to approach the pipe-nipple connection at the proper angle, ensuring perpendicular alignment while maintaining simple attachment operations.
Solution Approach 2:
The hose clamp holding portion with its guide surface enables the hose clamp to self-align and self-position correctly during attachment. The geometry of the holding portion automatically guides the clamp into the proper orientation without requiring precise manual alignment by the operator.
2Ease of operation
If the hose clamp is held in diametrically expanded state during attachment, then the clamp can be easily positioned on the pipe, but additional structural components are required to maintain this state
Solution Approach 1:
The hose clamp holding portion utilizes the radial dimension to hold the hose clamp in an expanded state. By providing support surfaces that contact the inner circumference of the hose clamp, it maintains the clamp in a ready-to-attach configuration without requiring additional active mechanisms.
Solution Approach 2:
The hose clamp's own elasticity serves the dual purpose of enabling easy positioning when expanded and providing secure attachment when released. The material properties of the hose clamp itself are utilized to maintain the expanded state during positioning, eliminating the need for separate expansion mechanisms.
3Reliability
If the hose clamp is pre-attached to the pipe before connection, then the connection is more secure, but the risk of damage and loss increases during handling
Solution Approach 1:
The hose clamp holding portion performs the preliminary action of positioning and securing the hose clamp to the nipple before the pipe is fully connected. This ensures the clamp is correctly positioned and secured in advance, preventing damage during subsequent handling and connection operations.
Solution Approach 2:
The holding portion serves as an intermediary that temporarily secures the hose clamp in a protected position on the nipple. This intermediate securing mechanism prevents the clamp from being damaged or lost during pipe handling while allowing easy removal when needed for maintenance.

AI summary
A pipe joint includes a joint main body comprising a nipple disposed in such a manner that a distal end is directed to one side in an axial direction and a hose clamp holding portion provided at a proximal end of the nipple and configured to be brought into abutment with an inner circumferential surface of a hose clamp which is biased in a diametrically narrowing direction so as to hold the hose clamp in a diametrically expanded state.
