Solution Overview

Problem

Current methods for monitoring heat stress in ruminants are time-consuming and costly, requiring manual observation and analysis of physical characteristics, body temperature, respiration rate, and blood, milk, or urine samples.

Innovation Solution

A method using an activity measurement unit with a motion sensor and processor attached to the ruminant to measure movement patterns indicative of panting or rumination, allowing for the determination of heat stress without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual observation and analysis of physical characteristics, body temperature, respiration rate, and blood/milk/urine samples is used to monitor heat stress, then accurate data on heat stress can be obtained, but the process is time-consuming and expensive

Engineering Contradiction:

Improveaccuracy of heat stress dataVSAvoidtime required for manual monitoring

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical observation and physical measurement systems with an automated electronic activity measurement unit. The motion sensor detects movement patterns (panting, rumination, lying down) and the processor analyzes this data to determine heat stress status, eliminating the need for manual physical examination and laboratory analyses while maintaining measurement accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The ruminant essentially monitors itself through its own movement patterns. The activity measurement unit attached to the animal automatically detects its physiological behaviors (panting, rumination, lying down) and interprets these as indicators of heat stress, eliminating the need for external manual intervention and continuous human observation.

Inventive Principle:

Principle #25Self-service

2Measurement precision

Engineering Contradiction:

Improveaccuracy of heat stress dataVSAvoidcost of manual monitoring

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent replaces expensive manual monitoring systems involving veterinarians, laboratory analyses, and multiple measurement devices with a single affordable activity measurement unit. The motion sensor and processor combination provides accurate heat stress detection at a fraction of the cost, eliminating expenses related to manual examination, sample collection, and laboratory testing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The activity measurement unit represents a low-cost, disposable or easily replaceable device compared to the expensive manual monitoring system. The unit uses inexpensive motion sensors and processing circuits that can be mass-produced at low cost, making continuous monitoring economically viable for farmers without requiring expensive veterinary services or laboratory infrastructure.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Productivity

If activity measurement unit with motion sensor and processor is used to measure movement patterns, then manual observation and analysis is reduced, but the system must accurately distinguish between panting, rumination, and other movements

Engineering Contradiction:

Improveefficiency of heat stress monitoringVSAvoiddifficulty of distinguishing movement types

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the analysis of movement patterns into distinct categories: panting (rapid mouth movements), rumination (head movements with jaw articulation), and lying down (complete body movement). The processor analyzes specific motion characteristics of each segment to accurately identify the behavior type, enabling reliable heat stress detection while maintaining high productivity through automated monitoring.

AI summary

Providing data indicative of heat stress in a ruminant using an activity measurement unit attached to the ruminant that includes a motion sensor and a processor is described. The method comprises measuring, using the motion sensor, ruminant movement of the ruminant over time; and determining, using the processor, that the measured ruminant movement is a repetitive movement indicative of either panting or rumination. A movement pattern indicative of panting and a movement pattern indicative of rumination both include one or more similar parameter values. The method further includes establishing at least one of: whether the repetitive movement is indicative of panting, and/or whether the repetitive movement is indicative of ruminating. The establishing includes: detecting, from the measured ruminant movement the occurrence of a belch action; and identifying, when for at least a predetermined time period the occurrence of the belch action is absent, that the repetitive movement is indicative of panting, for providing the data indicative of heat stress.
