Adjustable Teat Cup Positioning for Consistent Dairy Teat Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teat cleaning and treatment systems for dairy cows are inefficient, as they require manual labor, are inconsistent due to teat size and shape variations, and fail to thoroughly apply pre-dip and post-dip solutions, leading to potential milk contamination and infection risks.
Innovation Solution
A teat preparation system using a lightweight handpiece or robotic arm with a control unit that delivers high-pressure air and solutions to clean, dry, and apply post-dip solution automatically, featuring interchangeable spray cylinders and programmable logic control for precise operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual cleaning and treatment methods are used, then flexibility and adaptability to different teat sizes are maintained, but cleaning consistency and thoroughness deteriorate, leading to potential contamination
Solution Approach 1:
The system employs an adjustable teat cup positioner that can dynamically adjust the position and orientation of the teat cup to match varying teat sizes and shapes. The positioner includes adjustable arms and mounting mechanisms that allow operators to customize the setup for each teat, ensuring consistent treatment across different anatomical variations while maintaining adaptability.
Solution Approach 2:
The automated treatment system integrates multiple functions into a single apparatus: pre-dip application, air drying, stripping, and post-dip application. This multi-functional design ensures that all cleaning and treatment steps are performed consistently on every teat, eliminating the variability inherent in manual processes while accommodating different teat sizes through adjustable positioning.
2Reliability
If automated systems are used to improve cleaning consistency, then labor requirements increase and system complexity worsens
Solution Approach 1:
The automated treatment system is divided into distinct functional modules: a pre-dip application module, an air drying module, a stripping module, and a post-dip application module. Each module performs a specific function and can be independently adjusted or maintained. This segmentation reduces overall system complexity by making each component simpler and more manageable while achieving consistent multi-step treatment.
Solution Approach 2:
The system incorporates automatic air drying that eliminates the need for manual towel drying, and the stripping function automatically performs the mechanical squeezing and pulling action. These self-service features reduce the need for complex manual operations while maintaining treatment consistency, simplifying the overall process control.
3Productivity
If high-pressure air is used for drying, then towel usage is eliminated, but the risk of forcing solution into the teat increases
Solution Approach 1:
The air drying system uses targeted, localized air streams directed at specific areas of the teat and surrounding skin. The air flow is concentrated where moisture needs to be removed but is carefully controlled to avoid high-pressure direct contact with the teat opening. This localized approach maintains drying efficiency while preventing harmful forcing of solutions into the teat.
Solution Approach 2:
The system controls the pressure, flow rate, and direction of the air stream as adjustable parameters. By optimizing these parameters, the system achieves effective drying without excessive pressure that could force solutions into the teat. The parameters can be adjusted based on the specific treatment stage and teat characteristics.
4Adaptability or versatility
If exchangeable components are used to accommodate different teat sizes, then adaptability improves, but device complexity and maintenance requirements worsen
Solution Approach 1:
The system uses exchangeable teat cups and positioner components that can be independently replaced. Each component is designed as a separate, standardized module that interfaces with the main system through simple connection mechanisms. This segmentation allows individual components to be replaced without affecting the entire system, simplifying maintenance and repair while maintaining adaptability to different teat sizes.

AI summary
A teat treatment apparatus to clean and prepare bovine teat before milking or to sanitize the teat after milking. The apparatus, which is connected to a control unit, includes a holder with teat receiving body with at least one high-pressure air, pre-dip, and post-dip port. Inside the teat receiving body is an exchangeable spray cylinder with different size bore diameters designed to be used with different size teats. The holder may be a handpiece operated manually, or a support arm integrated with a robotic system with a track parallel to a row of bovines to be milked. When used in a robotic system, two or more teat receiving bodies may be adjusted, enabling the spacing and orientation of each teat receiving body to be adjusted. Additionally, a deflection cap with an optional diffuser enhances functionality.
