Multi-Lumen Hose Nipple Bracing for Fluid-Tight Single-Clamp Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-lumen hose connection nipples face challenges in providing a secure, fluid-tight coupling while minimizing manufacturing complexity and avoiding deformation or damage due to clamping pressure, particularly in sanitary technology applications.
Innovation Solution
A multi-lumen hose connection nipple design featuring a nipple base section with integral hose lumen plug-in sockets and a socket bracing structure that supports the sockets against radial pressure, allowing for a single hose clamp to achieve fluid-tight coupling without separate sealing measures, and a one-piece connecting piece strut structure for simplified manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single hose clamp is used to achieve fluid-tight coupling, then manufacturing complexity is reduced, but the hose lumen plug may deform or damage due to clamping pressure
Solution Approach 1:
The socket bracing structure provides localized reinforcement at the critical socket interior region where clamping pressure acts, while the rest of the hose lumen plug maintains its original design. This localized support prevents deformation at the socket interface without requiring structural changes throughout the entire component, thus maintaining ease of manufacture while protecting against pressure-induced damage
Solution Approach 2:
The socket bracing structure acts as a pre-installed support system that cushions the socket interior against the radial clamping pressure before the pressure can cause deformation or damage. This preemptive reinforcement allows the use of a single hose clamp without compromising the integrity of the hose lumen plug
2Reliability
If separate sealing measures are implemented for individual hose lumen insertion sockets, then fluid-tight coupling is improved, but device complexity increases
Solution Approach 1:
The socket bracing structure combines multiple functions into a single integrated component: it provides structural support to prevent deformation, creates a fluid-tight barrier through its design, and eliminates the need for separate sealing elements. This merging of support and sealing functions into one structure achieves reliable fluid-tight coupling while reducing device complexity
Solution Approach 2:
The socket bracing structure serves multiple purposes simultaneously: it reinforces the socket interior against pressure, provides the sealing interface for fluid-tight coupling, and simplifies the overall assembly by replacing what would otherwise require multiple separate components. This multi-functionality achieves both improved reliability and reduced complexity
