Electrical Teat Dipping for Rapid Teat Canal Closure

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional teat dipping methods fail to provide full protection against mastitis as the teat canal remains open for at least 2 hours after milking, creating an environment conducive to bacterial and viral entry.

Innovation Solution

Combining electrical field stimulation with teat dipping to rapidly close the teat canal by applying antiseptic solution within 5 ms using adjustable frequency and current signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional teat dipping method is used, then antiseptic solution is applied to teats, but the teat canal remains open for at least 2 hours after milking allowing bacterial entry

Engineering Contradiction:

Improveprotection against mastitisVSAvoidbacterial entry through open teat canal

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the purely chemical/mechanical teat dipping method with an electrical field-based system. Electrical stimulation is applied to the teat canal to induce rapid closure of the sphincter muscle, closing the canal within seconds rather than leaving it open for hours. This electrical intervention works in conjunction with the antiseptic solution to immediately prevent bacterial entry.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent applies electrical stimulation to close the teat canal immediately after milking and antiseptic application, before bacteria can enter the open canal. By closing the canal in the preliminary phase (within seconds), the system prevents the harmful effect of bacterial entry that would occur during the subsequent 2-hour period if only conventional dipping were used.

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If teat canal remains open for 2 hours after milking, then natural physiology is maintained, but exposure to bacteria and viruses increases

Engineering Contradiction:

Improvenatural teat canal physiologyVSAvoidbacterial and viral exposure

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent uses periodic electrical stimulation applied at specific intervals after milking to trigger rapid closure of the teat canal. The electrical pulses are applied in a controlled periodic manner to induce muscle contraction and canal closure, transitioning the system from a prolonged open state to a closed protective state within seconds.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The natural physiological closure process that would take hours is replaced by electrical field-induced muscle contraction, which achieves closure within seconds. This substitution maintains the protective function of canal closure while dramatically reducing the exposure time to pathogens.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If electrical field stimulation is applied to close teat canal rapidly, then bacterial entry is minimized, but device complexity increases

Engineering Contradiction:

Improveteat canal closure speedVSAvoidelectrical stimulation system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The electrical stimulation device is designed to integrate multiple functions: it delivers electrical pulses for canal closure, monitors the teat condition, and coordinates with the antiseptic application system. This multi-functionality reduces the need for separate devices and simplifies the overall system architecture despite the advanced capabilities required for rapid closure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The electrical stimulation system is designed to be self-regulating, using feedback from sensors to automatically adjust pulse parameters and timing. The system self-calibrates and manages its own operation, reducing the need for complex external control systems and minimizing overall device complexity while maintaining reliable rapid closure functionality.

Inventive Principle:

Principle #25Self-service
