Solution Overview

Problem

Current milking systems face challenges in efficient maintenance, particularly in identifying and replacing worn-out parts like teat liners, milk lines, and pulsation lines, which often require manual intervention and lead to logistical issues and wastage.

Innovation Solution

Integration of a 3D printer connected to a computer system that monitors the milking apparatus and generates signals for part replacement, allowing on-site production of characterized parts such as teat liners, milk lines, and pulsation lines, reducing the need for manual stock management and minimizing waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual monitoring and replacement of wearing parts is used, then operational simplicity is maintained, but maintenance efficiency and productivity deteriorate due to manual identification and retrieval of parts

Engineering Contradiction:
Improvemaintenance efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables automatic self-monitoring of wearing parts through sensors that detect wear conditions and trigger replacement signals without human intervention. The 3D printer automatically receives instructions and produces replacement parts, eliminating the need for manual monitoring and part retrieval.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical processes of inspecting, identifying, and retrieving wearing parts are replaced by an automated electronic monitoring system with sensors, computer control, and 3D printing technology. The system substitutes human-operated mechanical retrieval with automated digital monitoring and additive manufacturing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of time

If extensive stock of wearing parts is maintained, then immediate replacement is possible, but storage space requirements and administrative overhead increase

Engineering Contradiction:
Improvepart replacement timeVSAvoidstorage space
Core Design Contradiction:
Loss of timeVSArea of stationary object

Solution Approach 1:

The system extracts the essential functional characteristics of wearing parts and stores them digitally as 3D printing models rather than maintaining physical stock. Only the necessary raw materials are stored, while the specific part configurations are retrieved from digital databases and printed on-demand.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system changes the state of part storage from physical inventory to digital information. Wearing part specifications are converted into digital 3D models and stored in a database, allowing instant retrieval and customization without physical storage requirements. Parts are manufactured with precise parameter control through 3D printing.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If diverse wearing part variants are stocked, then all animal types can be serviced, but inventory management complexity and wastage of obsolete parts increase

Engineering Contradiction:
Improvepart compatibilityVSAvoidstock wastage
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The 3D printer serves as a universal manufacturing platform that can produce multiple variants of wearing parts for different animal types and milking system configurations. A single device replaces the need to maintain separate physical inventories of diverse part variants, providing on-demand customization.

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

Solution Approach 2:

The system transitions from static physical inventory to dynamic on-demand manufacturing. Part variants are not fixed in stock but are dynamically generated based on real-time requirements detected by the monitoring system. The 3D printer adapts its production to match current needs, eliminating obsolete stock before it becomes waste.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If manual part retrieval and packaging is required, then operator control is maintained, but time consumption and operational complexity increase

Engineering Contradiction:
Improvemaintenance simplicityVSAvoidpart retrieval time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs self-service by automatically detecting when wearing parts need replacement and triggering the 3D printer to produce new parts. The computer system autonomously manages the entire process from monitoring to manufacturing, eliminating manual intervention in part retrieval and preparation.

Inventive Principle:
Principle #25Self-service

AI summary

A milking system (1) comprises milking apparatus for milking of dairy animals, and comprising a plurality of wearing parts, inclusive of teat liners (11) and/or milk lines (12) and/or pulsation lines (13), and a computer system (7) configured to control and/or monitor the milking apparatus, and to generate a signal which indicates that one of the wearing parts should be replaced and provides a characterization of that wearing part, wherein the milking system further comprises a 3D printer (20), which is operatively connected to the computer system and which is configured to print the characterized part on the basis of the generated signal. Thus it is not necessary to keep an unnecessarily large stock of spare parts, but it becomes possible to directly provide the spare parts quickly, cheaply and with less chance of errors. Moreover, it is thus possible to, tailor the parts, especially teat liners, to animals.
