Hose-Line Connector Rib Structure for Anti-Twist Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose-line connectors require cumbersome double radial clamping for secure hose assembly and sealing, which can lead to axial displacement and leakage due to twisting of the hose line, and lack mechanical reinforcement.
Innovation Solution
A hose-line connector with a radially protruding rib structure featuring circumferential and longitudinal ribs that form chamber-like recesses, allowing for a single radial clamp and preventing twisting, while enhancing mechanical reinforcement and sealing efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If double radial clamping is used in existing hose-line connectors, then secure hose assembly and sealing are achieved, but the hose assembly becomes cumbersome and requires two radial clamps
Solution Approach 1:
The retaining segment is segmented into multiple functional ribs: at least one circumferential rib for axial retention and at least one longitudinal rib for torsion prevention. This segmentation allows a single radial clamp to achieve both sealing and mechanical reinforcement functions that previously required double clamping
Solution Approach 2:
Different regions of the retaining segment are given different local qualities through the rib structure. The circumferential rib provides axial retention, the longitudinal rib provides torsion resistance, and together they create chamber-like recesses that enhance mechanical reinforcement. This localized functional differentiation eliminates the need for a second radial clamp
2Ease of manufacture
If existing hose-line connectors use simple cylindrical retaining segments, then manufacturing is simple, but the hose line can twist and displace axially causing leakage
Solution Approach 1:
The retaining segment is divided into multiple ribs with specific orientations (circumferential and longitudinal) that provide targeted anti-twisting and axial retention functions. This segmented structure maintains manufacturing simplicity while adding torsion-resistant capabilities
Solution Approach 2:
The rib structure introduces asymmetric features to the otherwise cylindrical retaining segment. The combination of circumferential and longitudinal ribs creates an asymmetric pattern that effectively prevents twisting while maintaining rotational symmetry in the overall connector design
3Device complexity
If a single radial clamp is used, then the hose assembly is simplified, but mechanical reinforcement and prevention of twisting are insufficient
Solution Approach 1:
The retaining segment incorporates localized structural features (ribs and chamber-like recesses) that provide mechanical reinforcement and torsion resistance at specific locations. This allows a single radial clamp to achieve the mechanical strength previously requiring double clamping
Solution Approach 2:
The rib structure adds dimensional complexity to the retaining segment by creating three-dimensional chamber-like recesses between the ribs. This dimensional enhancement provides mechanical reinforcement and torsion resistance without adding additional clamps
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 rib structure ensures a tight, reliable hose connection with improved sealing and mechanical hold, preventing axial displacement and leakage, and simplifies the hose assembly process by eliminating the need for a second radial clamp.
Implementation Method 1
its hose wall is pressed under elastic deformation onto the rib structure. Thus the hose wall is pressed in regions into the chamber-like recesses formed between the ribs, so that the hose wall practically surrounds the ribs up to the otherwise cylindrical perimeter of the retaining segment, and thus promotes a positive-locking connection

AI summary
A hose-line connector, with a connection part having at least one elongated hose connection for slipping a hose line onto the hose connection. The hose connection has a sealing segment having a circumferential sealing surface at a free front end and a retaining segment axially adjacent thereto as a clamping region for the circumferential radial clamping of a hose line. On the outer circumference of the retaining segment, the retaining segment has a radially protruding rib structure, which includes at least one circumferential rib in the form of an annular ridge and at least two longitudinal rib distributed about the circumference and extending axially or at an angle to the axial direction.
