Solution Overview

Problem

Existing short milk conduits face difficulties in quick and reliable attachment to milk-receiving members like claws due to their design, which hinders efficient milking operations.

Innovation Solution

The milk conduit features an outer sleeve section with projections extending less than 180°, allowing for a bayonet coupling mechanism that enables quick attachment and secure locking with a coupling member, along with a tapering milk channel for a tight seal, facilitating easy connection and reliable operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the outer sleeve section is angled to provide a permanently bent portion, then the milk conduit can be attached to the teatcup, but the attachment to the milk-receiving member becomes difficult and time-consuming

Engineering Contradiction:
Improveattachment to teatcupVSAvoidattachment to milk-receiving member
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The outer sleeve section is divided into multiple projections (first projection and second projection) spaced around the circumference, each engaging with corresponding coupling members on the milk-receiving member. This segmentation allows the conduit to be attached through a simple turning motion of less than 180 degrees, making the attachment process quick and easy while maintaining the bent portion configuration for teatcup connection.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a conventional connection design is used, then the structure is simple, but the connection is not quick and reliable

Engineering Contradiction:
Improveconduit structureVSAvoidconnection reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The outer sleeve section is pre-formed with projections at specific angular positions (less than 180 degrees apart) before attachment. These projections are positioned in advance to engage with the coupling members on the milk-receiving member, ensuring that when the conduit is turned and attached, the connection is immediately secure and reliable without requiring additional adjustment or complex mechanisms.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention refers to a milk conduit, a milk conduit device, a milk- receiving member and a milking member. The milk conduit (3) comprises a first end portion (31) to be connected to a milk-receiving member. The first end portion comprises an inner sleeve section made of a first material and an outer sleeve section joined to the inner sleeve section (35) and made of a second material, which is more rigid than the first material. The outer sleeve section comprises an outer peripheral surface (38) and at least one projection (39) extending outwardly from the outer peripheral surface. The projection has a peripheral extension of less than 180°, and is engaged by a coupling member on the milk-receiving member.
