Solution Overview

Problem

Manual inspection for determining breeding traits in dairy cattle is labor-intensive, costly, and subjective, limiting the frequency and accuracy of breeding value assessments in dairy farms.

Innovation Solution

A combined teat position and breeding rating determining arrangement using a three-dimensional camera in an automatic milking system to record and process images of the udder, automatically determining teat shapes and calculating breeding ratings based on these shapes, eliminating the need for manual inspection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual inspection is used to determine breeding traits, then breeding rating assessment can be performed, but it is labor-intensive and costly

Engineering Contradiction:
Improvebreeding rating assessment accuracyVSAvoidinspection frequency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical inspection with an automated optical measurement system. A 3D camera captures images of the udder and teats, and image processing algorithms automatically determine teat shapes and calculate breeding ratings, eliminating the need for manual measurement and assessment.

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

Solution Approach 2:

The system enables self-assessment of breeding traits by the animal itself during routine milking operations. The 3D camera automatically captures images and the processing system independently calculates breeding ratings without requiring external expert intervention, making the assessment process autonomous and continuous.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If manual inspection is used to determine breeding traits, then breeding rating can be calculated, but it is subjective and dependent on the inspector

Engineering Contradiction:
Improvebreeding rating objectivityVSAvoidtime for breeding assessment
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces subjective human judgment with objective computational analysis. The image processing system automatically extracts geometric features of teats and udder from 3D images and calculates breeding ratings based on predetermined criteria, eliminating inspector subjectivity and variability.

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

Solution Approach 2:

The system transforms physical breeding traits into quantifiable digital parameters through 3D imaging. Teat shape, udder conformation, and other breeding-relevant features are converted into measurable geometric parameters that can be objectively analyzed and compared, removing dependence on human perception and judgment.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If manual inspection is used for breeding traits, then assessment can be performed, but only at rare occasions due to labor constraints

Engineering Contradiction:
Improvebreeding assessment frequencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent integrates breeding rating determination into the existing automatic milking system. The same 3D camera and image processing infrastructure used for teat position detection during milking is also utilized for breeding trait assessment, allowing multiple functions (milking control and breeding evaluation) to share common hardware and software resources.

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

Solution Approach 2:

The system combines breeding assessment with routine milking operations. By merging the breeding evaluation process with the existing milking workflow, the patent eliminates the need for separate inspection sessions, enabling continuous breeding rating updates without adding significant system complexity or requiring additional dedicated equipment.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A combined teat position and breeding rating determining arrangement for a milking system having a milking stall, a movable robot arm for automatically attaching teat cups to the teats of the milking animal, and a control device for controlling the movement of the robot arm based on determined positions of the teats of the milking animal. The arrangement includes a three-dimensional camera directed towards the udder of the milking animal that repeatedly records three-dimensional images of the udder, and a processing unit that repeatedly detects the udder or teats of the milking animal, determines their positions based on the recorded three-dimensional images, automatically determines the shapes of the udder or teats based on the repeatedly recorded three-dimensional images, and automatically calculates a breeding rating based on the determined shapes of the udder or teats of the milking animal.
