Pipe Connector Pressing Structure for Stable Sealing Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe connecting apparatuses face issues with unstable fixation and potential damage to pipes due to deformation of the grip member, as they lack a separate pressing mechanism to prevent the large diameter part from deforming unintentionally and causing the connector to lose its sealing efficiency.
Innovation Solution
A pipe connecting apparatus with a connector featuring a large diameter part and a pressing part of smaller diameter, where the pressing part is continuously formed along the lengthwise direction to surround the pipe, and a grip member with bosses that are designed to deform and press the pipe's outer surface, preventing penetration and ensuring stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only the large diameter part is pressed to fix the grip member and sealing member, then the fixation is achieved, but the large diameter part deforms unintentionally and the connector cannot stably accommodate the components due to spring back phenomenon
Solution Approach 1:
The connector is divided into two distinct functional parts: a large diameter part for accommodating the grip member and sealing member, and a pressing part for applying compression force. This segmentation allows each part to perform its specific function without interfering with the other, preventing unwanted deformation while achieving stable fixation.
Solution Approach 2:
The pressing part acts as an intermediary element that transmits the compression force from the external pressing mechanism to the grip member and sealing member. It mediates between the external force and the components to be fixed, ensuring controlled application of force without causing deformation to the large diameter part.
2Ease of operation
If the large diameter part is pressed without additional force on opposite sides, then the pressing operation is simple, but the large diameter part comes over or deforms unintentionally
Solution Approach 1:
By separating the pressing function into a dedicated pressing part, the operation remains simple (pressing the connector axially) while the pressing part itself provides the necessary structural support to prevent deformation of the large diameter part during the pressing operation.
3Strength
If the grip member penetrates into the outer peripheral surface of the pipe, then the fixation strength is improved, but the pipe is damaged
Solution Approach 1:
The boss structure is designed with specific geometric parameters (protrusion height, curvature radius, contact area) that allow it to deform and conform to the pipe surface without penetrating through. The curved end design changes the stress distribution, enabling the boss to distribute the fixation force over a larger area, achieving strong fixation without pipe damage.
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 solution prevents the large diameter part from deforming unintentionally, maintains stable fixation of the pipe, and minimizes damage by curving the boss ends to recess and deform widely, ensuring effective sealing and preventing pipe damage.
Implementation Method 1
at least a portion of the grip member presses an outer peripheral surface of the pipe in a condition in which an outer peripheral surface of the large diameter part is pressed

AI summary
A pipe connecting apparatus includes: a connector including a large diameter part having a hollow, into which a pipe is inserted, therein and in which at least any one of opposite ends of the hollow has a larger inner diameter such that an accommodation space is formed inside the one end of the hollow, and a pressing part continuously formed along a lengthwise direction of the large diameter part in a direction in which the pipe is inserted, having a smaller diameter than the large diameter part, and formed to surround an outer peripheral surface of the pipe; a ring-shaped sealing member provided in the accommodation space and surrounding the pipe on the outside of the pipe; and a grip member provided in the accommodation space to be adjacent to the sealing member.
