Solution Overview

Problem

Current milking machine systems require extensive movement and time to position teat cups on an animal's udder, causing anxiety and inefficiency in the milking process due to the need for separate positioning of each teat cup, which can lead to unnecessary contact with the animal and increased space requirements.

Innovation Solution

A double grab mechanism mounted on a milking machine arm, featuring two housing parts with pivoting and sliding capabilities, allows for simultaneous positioning of two teat cups without increasing the arm's width, using magnets for secure teat cup attachment and detachment, and a sliding mechanism to manage space effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a single grab is used to apply teat cups one by one, then the positioning precision can be maintained, but the time required for positioning increases and the animal becomes anxious

Engineering Contradiction:
Improvepositioning precisionVSAvoidpositioning time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines two teat cup holders into a single double grab assembly that can be mounted on one arm. This allows two teat cups to be positioned simultaneously or in quick succession, reducing the total positioning time while maintaining precision through the shared sensor and arm positioning system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The double grab pre-positions two teat cups in the holders before approaching the animal. This preliminary preparation allows the system to apply both teat cups in one approach motion, eliminating the need for separate positioning trips and reducing overall positioning time.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If multiple teat cups are brought simultaneously using a wider arm configuration, then the positioning time is reduced, but the space required increases and contact with the animal is increased

Engineering Contradiction:
Improvepositioning timeVSAvoidarm width
Core Design Contradiction:
Loss of timeVSArea of stationary object

Solution Approach 1:

The patent positions the two holders in a vertical arrangement (one above the other) rather than side-by-side horizontally. This vertical stacking allows two teat cups to be held simultaneously without increasing the horizontal width of the arm, thus reducing space requirements and minimizing contact with the animal while maintaining the ability to position multiple cups efficiently.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If the arm width is increased to accommodate multiple holders, then multiple teat cups can be positioned simultaneously, but the space requirements and animal contact increase

Engineering Contradiction:
Improvemilking efficiencyVSAvoidspace requirement
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The vertical stacking of holders in the double grab assembly enables simultaneous holding of multiple teat cups without expanding the horizontal footprint of the arm. This maintains compact space requirements while improving productivity through efficient multi-cup positioning.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The double grab assembly integrates two complete holder units within a compact structure that mounts on a single arm. This nested configuration allows multiple functional units to coexist in a space-efficient manner, improving productivity without proportionally increasing the overall system size.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

This invention is related to a double grab, its rinsing cup and milking machine provided therewith, and the method for automatically applying teat cups to the teats of an udder of an animal to be milked. The double grab according to the invention includes: - a first housing part designed to hold a first teat cup; - a second housing part, installed substantially in a horizontal plane next to the first housing part, designed to hold a second teat cup; - whereby each housing part is provided with separate pivoting means that can be activated and is designed to make the related housing part pivot around a pivoting axis which in use, extends substantially in a horizontal direction, substantially in a widthwise direction of the arm.
