Hydraulic Pipe Connector with Catch Element and Annular Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting means for hydraulic elements fail to provide a simple and reliable method for connecting and disconnecting pipe connecting pieces in a fluid-tight manner, lacking ease of use and mechanical load-bearing capacity.
Innovation Solution
The solution involves a first pipe connecting piece with a recess and a second pipe connecting piece featuring a collar and annular space, along with a securing part containing catch elements that facilitate a fluid-tight connection by inserting the catch element into an aperture, allowing for easy assembly and disassembly without additional retaining means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connecting means are used for hydraulic elements, then the connection can be established, but the process is complex and requires additional retaining means
Solution Approach 1:
The connecting means is divided into distinct functional elements: a first pipe connecting piece with an aperture, a second pipe connecting piece with a collar and annular space, and a separate securing part with catch elements. This segmentation allows each component to perform its specific function independently, simplifying the overall assembly and disassembly process while reducing the need for additional retaining means.
Solution Approach 2:
The first pipe connecting piece is introduced into the annular space formed by the collar and outer piece of pipe of the second pipe connecting piece. The catch elements of the securing part are inserted through apertures and engage with recesses on the first pipe connecting piece, creating a nested configuration that simplifies the connection structure and eliminates the need for separate retaining means.
2Reliability
If a secure and fluid-tight connection is established, then reliability is improved, but the mechanical load-bearing capacity may be compromised
Solution Approach 1:
The collar of the second pipe connecting piece is designed with a specific geometry that creates an annular space with particular local properties. The catch elements of the securing part are positioned to engage with recesses at specific locations on the first pipe connecting piece, creating localized high-strength connection points that maintain both fluid-tightness and mechanical load-bearing capacity.
Solution Approach 2:
The connecting means employs a composite structure combining the collar and outer piece of pipe of the second pipe connecting piece with the first pipe connecting piece and securing part. This composite configuration distributes mechanical loads across multiple components and connection points, enhancing both the fluid-tight seal and the overall mechanical strength of the assembly.
3Adaptability or versatility
If the connection allows rotational movement, then adaptability is improved, but the stability of the connection may be reduced
Solution Approach 1:
The connecting means is designed to accommodate dynamic rotational movement between the first and second pipe connecting pieces while maintaining the secured connection. The catch elements engaging with recesses allow for controlled rotation, providing adaptability for different installation orientations and operational requirements while preserving connection stability through the securing part.

AI summary
The invention relates to a connecting device having a first pipe connecting piece, a second pipe connecting piece and a securing part. The two pipe connecting pieces are adapted to be connected to one another in a releasable and fluid-tight manner by the securing part. The first pipe connecting piece has at least one recess on the outside, and the second pipe connecting piece has a collar and an outer piece of pipe, which between them form an annular space bounded on one side in the axial direction and which accommodates a sealing element. The outer piece of pipe has at least one aperture. The first pipe connecting piece is adapted to be introduced into the annular space. The securing part has at least one catch element, which can be inserted into an aperture, thereby entering a recess. A filter device with such a connecting device is also provided.
