Solution Overview
Problem
Existing multi-lumen hose connector nipples face challenges in providing secure, fluid-tight connections while minimizing production complexity and avoiding deformation or damage to the hose lumina due to radially inward clamping pressures.
Innovation Solution
A multi-lumen hose connector nipple design featuring a nipple base section with integral hose lumen plug-in sockets and a strutting structure that supports the connecting pieces, allowing for secure fluid-tight coupling with a single hose-clamping mechanism, eliminating the need for separate sealing measures and enabling efficient manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multi-lumen hose connector nipple is designed with integral hose lumen plug-in connecting pieces, then manufacturing complexity is reduced and production efficiency is improved, but the hose lumen plug-in connecting pieces may deform or damage due to radially inward clamping pressure from a single hose-clamping mechanism
Solution Approach 1:
The connector nipple is divided into functionally distinct components: the nipple base section and the hose lumen plug-in connecting pieces. This segmentation allows the base section to provide structural support and fluid conduit pathways while the connecting pieces are designed to interface with hose lumina, enabling specialized optimization of each component for its specific function.
Solution Approach 2:
The hose lumen plug-in connecting pieces are integrally formed with the nipple base section, merging two components into a single monolithic structure. This integration eliminates the need for separate sealing measures for each lumen and simplifies manufacturing, while the integral construction ensures rigid structural support that prevents deformation under clamping pressure.
2Reliability
If separate sealing measures are implemented for each lumen, then fluid-tight connection reliability is improved, but device complexity and production outlay increase
Solution Approach 1:
The connector nipple provides a unified fluid-tight connection structure where the nipple base section and all hose lumen plug-in connecting pieces form an integrated assembly. This merging of sealing functions into a single structural unit eliminates the need for multiple separate sealing measures, reducing device complexity while maintaining fluid-tight integrity across all lumina through the monolithic construction.
3Reliability
If multiple hose-clamping mechanisms are used to secure each lumen separately, then connection reliability is improved, but ease of manufacture deteriorates and production complexity increases
Solution Approach 1:
The design consolidates multiple clamping functions into a single hose-clamping mechanism that secures all hose lumina simultaneously to the integral connecting pieces. This merging of clamping operations into one action simplifies the manufacturing and installation process, eliminating the need for multiple separate clamping operations while maintaining secure connections for all lumina through the rigid integral structure.
Solution Approach 2:
The single hose-clamping mechanism is designed to perform multiple functions: it simultaneously secures multiple hose lumina to their respective connecting pieces, provides uniform radial support across all lumina, and ensures fluid-tight connections for the entire multi-lumen assembly, eliminating the need for multiple specialized clamping devices.

AI summary
A multi-lumen hose connector nipple and a multi-lumen hose equipped therewith. The multi-lumen hose connector nipple includes a nipple basic section through which a plurality of separate fluid conduits extend in each case between a first and a second nipple connector side, a plurality of hose lumen plug-in sockets integral with the nipple basic section, which sockets extend juxtaposed on the first nipple connector side with an intermediate hose lumen wall accommodation space left therebetween, wherein a socket interior space of each of the hose lumen plug-in sockets is assigned to a respective one of the fluid conduits and opens out axially, and a socket strutting structure within the socket interior space of at least one of the hose lumen plug-in sockets.
