Solution Overview

Problem

Current livestock management systems lack effective methods to determine successful insemination and monitor animal health status, particularly in a non-invasive and efficient manner.

Innovation Solution

An ear tag assembly with a primary temperature sensor to measure the outer ear temperature of an animal and a secondary ambient temperature sensor to detect localized temperature changes, correlating these readings to determine successful insemination and health status, such as ovulation or illness, without the need for intrusive measurements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional intrusive methods are used to determine successful insemination and monitor animal health, then measurement accuracy may be improved, but animal distress and operational complexity increase

Engineering Contradiction:
Improveinsemination detection accuracyVSAvoidanimal distress
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces intrusive mechanical or manual examination methods with a non-invasive electronic sensing system. Temperature sensors mounted on the ear tag continuously monitor temperature changes that indicate successful insemination, eliminating the need for physical examinations or intrusive procedures that would cause animal distress.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses ear temperature as an intermediary indicator to infer internal physiological states related to insemination success. Instead of directly measuring internal conditions, the system monitors the easily accessible outer ear temperature, which correlates with internal body temperature changes, providing indirect but accurate information without causing distress.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If continuous monitoring of animal temperature is implemented, then health status detection is improved, but energy consumption increases

Engineering Contradiction:
Improvehealth monitoring reliabilityVSAvoidtag energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic temperature monitoring rather than truly continuous monitoring. The control circuit is programmed to take temperature readings at specific intervals and compare them to detect trends indicating health issues or successful insemination. This periodic sampling maintains monitoring reliability while significantly reducing energy consumption compared to constant monitoring.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses the animal's own body temperature as the monitoring target, requiring no external power source or additional infrastructure. The passive temperature sensing leverages the natural thermal signature of the animal, allowing the tag to function with minimal energy input while maintaining high reliability in detecting temperature changes associated with health status.

Inventive Principle:
Principle #25Self-service

3Loss of information

If multiple sensors are integrated into the ear tag, then measurement capability is improved, but device complexity increases

Engineering Contradiction:
Improvehealth data completenessVSAvoidear tag structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent integrates multiple sensing capabilities into a single ear tag device that serves multiple functions. The temperature sensors can detect both successful insemination events and general health status changes, while the wireless communication module enables data transmission to various stakeholders. This multi-functionality approach consolidates what would otherwise require separate devices into one unified system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines temperature sensing, data processing, wireless communication, and power management into an integrated ear tag assembly. The control circuit merges temperature data from multiple sensors with animal identification information and transmits consolidated health records wirelessly, reducing the need for separate components and simplifying the overall system architecture despite the multiple sensing functions.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Apparatus and method for managing animals such as but not limited to livestock. An ear tag assembly (102, 400, 460, 480, 510) has a main body (120, 402), a backing member (130, 404) and a shaft (124, 408) that extends through an aperture through an outer ear (1 14, 1 86) of an animal (1 12) to interconnect the main body and the backing member. A primary temperature sensor (140, 436, 462, 484) obtains an outer ear temperature of the outer ear. An ambient temperature sensor (150, 406) obtains an ambient temperature of a surrounding environment external to the animal. A control circuit (170) receives the outer ear and ambient temperatures and determines a successful insemination of the animal has taken place by comparing the outer ear temperature and the ambient temperature over a selected time interval (506).
