Solution Overview

Problem

Existing ruminant behavior monitoring systems are cumbersome, fragile, and lack GPS capability and remote user interfaces, making it difficult to collect and analyze data on foraging behavior without disrupting the animals and are limited by weather conditions.

Innovation Solution

A halter-mounted system with dual piezoelectric jaw movement sensors, a data processor, data logger, and GPS capability that wirelessly communicates with a host computer to record and categorize jaw movements, allowing for remote monitoring of ruminant foraging behavior without interfering with the animal's natural behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If direct observation of grazing animals is used, then foraging behavior can be monitored, but the process is tedious, error-prone, and disrupts animal behavior

Engineering Contradiction:
Improveforaging behavior measurementVSAvoidobservation process
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical observation with automated electronic sensors. Piezoelectric sensors mounted on the animal's jaw automatically detect and record jaw movements, eliminating the need for human observers to physically watch and record behavior, thus resolving the contradiction between measurement precision and ease of operation

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

Solution Approach 2:

The monitoring system is designed to automatically collect, store, and transmit data without human intervention. The sensors self-record jaw movements and the system automatically transmits data wirelessly, allowing the animal to be monitored while continuing its natural behavior without human disruption

Inventive Principle:
Principle #25Self-service

2Loss of information

If prior art ruminant behavior monitors are used, then some behavior data can be collected, but the monitors are cumbersome, fragile, and frequently damaged or dismantled by other cows

Engineering Contradiction:
Improvebehavior data collectionVSAvoidmonitor durability
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent uses a flexible halter-mounted design with durable construction. The sensor unit is mounted on a halter that can be adjusted to fit different cow sizes, and the housing is designed to withstand rough handling and environmental conditions, preventing damage while maintaining data collection capability

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The monitoring system is divided into separate modular components: the sensor unit, the halter mounting, and the data transmission module. This segmentation allows each component to be optimized independently for durability and functionality, with the halter serving as a protective and adjustable mounting structure

Inventive Principle:
Principle #1Segmentation

3Loss of information

If prior art monitors lack GPS capability and remote user interface, then animals must be physically located and detained to access data, but this disrupts animal behavior and increases labor requirements

Engineering Contradiction:
Improvedata accessibilityVSAvoiddata retrieval process
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent replaces physical data retrieval with wireless digital communication. A radio transceiver module transmits behavior data wirelessly to a remote location, eliminating the need to physically locate and detain animals for data access, thus resolving the contradiction between data accessibility and ease of operation

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

Solution Approach 2:

The patent introduces a wireless communication intermediary (radio transceiver) that bridges the gap between the animal-mounted sensor and the remote user. This intermediary enables data transmission without physical contact with the animal, allowing remote data access while maintaining animal behavior naturalness

Inventive Principle:
Principle #24Intermediary (Mediator)

4Loss of information

If human presence is used for observation, then behavior data can be collected, but human presence significantly alters the foraging behavior of some animals

Engineering Contradiction:
Improvebehavior data collectionVSAvoidbehavior alteration
Core Design Contradiction:
Loss of informationVSObject-generated harmful factors

Solution Approach 1:

The monitoring system performs self-service data collection without human presence. The automated sensors continuously record jaw movements and the system independently processes and transmits data, eliminating the harmful effect of human presence on animal behavior while maintaining comprehensive data collection

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent substitutes human observation with automated electronic sensing. Piezoelectric sensors detect jaw movements and convert them to electrical signals for processing, replacing the human observer entirely and eliminating the behavioral alteration caused by human presence

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

AI summary

A system for monitoring ruminant animal foraging that utilizes a piezoelectric film sensor in communication with a computer processor to record and characterize jaw movement data for the foraging ruminant animal. The processor applies pattern algorithms to categorize the jaw movement data so that the jaw movements are categorized as at least chewing, biting, ruminating, and/or idling.
