Solution Overview

Problem

Conventional head restraints for cattle in chutes cause discomfort and struggle, leading to inefficiencies and injuries during treatments like eye drop application and dehorning, as they allow head movement and require painful bull leads.

Innovation Solution

A head restraint system comprising a lower neck restraint, an upper neck restraint, and a nose restraint that can be affixed to existing chutes, allowing for secure, humane restraint with minimal animal movement, using adjustable and lightweight components to fit various head gate sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional head restraints (bull leads) are used to restrain cattle heads, then the animal's head can be held in place, but the animal experiences pain and struggle, making procedures difficult and time-consuming

Engineering Contradiction:

Improveease of head restraint applicationVSAvoidanimal pain and stress

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The head restraint is divided into multiple independent components: a head gate portion with side walls, a nose restraint portion, and a lower neck restraint portion. Each component can be adjusted independently to fit different animal sizes and provide customized restraint without causing pain.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The head restraint incorporates movable and adjustable components including side walls that can move inward, a nose restraint that can be positioned at different locations, and a lower neck restraint that adjusts to different neck sizes. This dynamic design allows the restraint to adapt to each animal individually, providing secure restraint without causing pain or struggle.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If conventional head restraints allow head movement from side to side or up and down, then the animal remains relatively comfortable, but procedures on the head become difficult and inaccurate

Engineering Contradiction:

Improveanimal comfortVSAvoidprocedure accuracy

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The invention combines multiple restraint functions into a single integrated head restraint system. The head gate portion, nose restraint portion, and lower neck restraint portion work together as one unified system that simultaneously prevents head movement in multiple directions while maintaining animal comfort, thereby enabling accurate head procedures.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The head restraint acts as an intermediary device between the animal's natural head movement tendencies and the need for procedural accuracy. It provides sufficient restraint to keep the head stable during procedures like eye drop application and dehorning, while being designed to minimize discomfort and struggle.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Strength

If heavy gauge steel is used for the chute structure to withstand cattle weight and strength, then the structure is strong and durable, but the rigid structure causes injury to animals during thrashing

Engineering Contradiction:

Improvechute structure strengthVSAvoidanimal injury

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The head restraint incorporates padded portions, particularly in areas where the animal's head and neck contact the restraint structure. This cushioning is built into the restraint design beforehand to prevent injury during the restraint application and procedure performance, while the overall chute structure maintains its heavy gauge steel construction for structural strength.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The present invention provides an improved head restraint that can be used in conjunction with conventional cattle chutes that are equipped with head gates. It provides the advantages of being humane by causing little or no discomfort to the cattle being restrained. Cattle being treated also tends to remain calm while being restrained utilizing the device of this invention. It offers much easier and faster means for providing care to positions on the head of the animal. Its implementation can accordingly lead to reduction in human labor requirements associated with treating a herd of cattle and generally leads to savings in medication by virtue of being able to more accurately apply eye drops, ointments, or powdered medications to the eyes of a cow having a very stabilized head as compared to loss of medication when dealing with a struggling animal that is jerking its head around during the procedure. Its use greatly reduces the risk of injury to the animal and the person administering the treatment to the animal. Head restraints of this invention offer the advantage of being capable of being affixed to existing chutes of differing sizes. This is because the improved head restraints of this invention are expandable to fit directly onto head gates of differing designs and sizes.
