Solution Overview

Problem

Existing milking systems face challenges in efficiently transporting milk from multiple milking stations to a main milk tank while ensuring effective cleaning of long conduits, which is crucial for maintaining milk quality and hygiene.

Innovation Solution

The system incorporates a transport conduit with a valve arrangement that forms a loop for efficient milk transport and switches to a single path for thorough cleaning, utilizing a cleaning liquid arrangement and pump to circulate cleaning solutions through the conduit, maintaining higher pressure for both milking and cleaning processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the transport conduit is configured as a loop with two flow paths for efficient milk transport, then milk transport efficiency is improved, but conduit cleaning effectiveness deteriorates

Engineering Contradiction:
Improvemilk transport efficiencyVSAvoidconduit cleaning effectiveness
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The valve arrangement dynamically changes the conduit configuration from a loop with two flow paths during milking to a single flow path during cleaning. This dynamic reconfiguration allows the system to optimize for milk transport efficiency during milking operations and cleaning effectiveness during cleaning operations, resolving the contradiction between these two requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The transport conduit is segmented into multiple flow paths that can be independently controlled by valve arrangements. This segmentation allows selective activation of one or two flow paths depending on operational requirements, enabling efficient milk transport when both paths are open and effective cleaning when only one path is active.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If cleaning liquid is circulated through the transport conduit for thorough cleaning, then cleaning effectiveness is improved, but system complexity increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning liquid arrangement is integrated with the existing transport conduit infrastructure, allowing the same conduit system to serve both milk transport and cleaning functions. The valve arrangement enables the cleaning liquid to circulate through the conduit without requiring separate dedicated cleaning lines, thus improving cleaning effectiveness while minimizing additional system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses its own transport conduit infrastructure for cleaning purposes, rather than requiring entirely separate cleaning equipment. The cleaning liquid circulates through the existing conduit system, utilizing the same physical pathways for both production and maintenance functions, thereby reducing overall system complexity.

Inventive Principle:
Principle #25Self-service

AI summary

An arrangement (2) for milking animals is disclosed. The arrangement (2) comprises at least one milking station (4), a transport conduit (6), a main milk tank (8) for storing milk from the at least one milking station (4), a connection conduit (10) extending from the transport conduit (6) to the main milk tank (8), and a cleaning liquid arrangement (16). From the milking station (4) a connection pipe (12) leads to the transport conduit (6) at a connection point (14). The arrangement (2) for milking animals comprises a valve arrangement (18). The cleaning liquid arrangement (16) is connected to the transport conduit (6) via the valve arrangement (18). The valve arrangement (18) is adapted to be positioned in at least a first position and a second position. In the first position the transport conduit (6) forms a loop such that two flow paths from the connection point (14) to the connection conduit (10) are provided by the transport conduit (6), and in the second position the loop is interrupted such that one flow path only from the connection point (14) to the connection conduit (10) is provided by the transport conduit (6).
