Solution Overview

Problem

Current methods for diagnosing ruminant acidosis, such as rumen pH measurement, are invasive, unreliable, and labor-intensive, failing to accurately detect acidosis in ruminants and posing welfare concerns for the animals.

Innovation Solution

Non-invasive methods for detecting acidosis in ruminants through analysis of biological fluids from the oral or nasal cavity, using systems and devices to measure solvents and volatile chemicals, combined with synthetic microbial ensembles and additives to treat and ameliorate acidosis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rumen pH measurement is used to diagnose acidosis, then a diagnostic method is provided, but the method is invasive, unreliable, and labor-intensive

Engineering Contradiction:

Improveacidosis detection accuracyVSAvoidoperational complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical invasive procedure of rumen pH measurement (tubing or ruminocentesis) with a non-invasive breath analysis system that detects volatile organic compounds and solvents through the animal's respiratory exhalation, eliminating the need for physical intrusion into the rumen while maintaining diagnostic capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses breath samples as an intermediary medium to indirectly assess rumen health status. Instead of directly measuring rumen pH, the system analyzes volatile organic compounds and solvents in the animal's breath that reflect rumen fermentation states, providing a reliable proxy measurement without invasive procedures

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If invasive rumen pH measurement is performed, then acidosis can be detected, but animal welfare is compromised

Engineering Contradiction:

Improveacidosis detection accuracyVSAvoidanimal welfare impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the harmful mechanical intrusion of rumen pH measurement with a non-invasive breath analysis system, eliminating physical damage to the animal's throat and rumen wall while maintaining the ability to detect acidosis through analysis of volatile organic compounds in respiratory exhalation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The animal voluntarily provides the diagnostic sample through normal breathing, eliminating the need for human intervention that causes harm. The breath sample is obtained naturally during routine handling, transforming the diagnostic process into a self-service mechanism that prioritizes animal welfare

Inventive Principle:

Principle #25Self-service

3Loss of information

If traditional pH measurement methods are used, then diagnostic information is obtained, but the process is labor-intensive and time-consuming

Engineering Contradiction:

Improvediagnostic information completenessVSAvoiddiagnostic time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent replaces the labor-intensive mechanical process of rumen pH measurement with an automated breath analysis system that rapidly detects volatile organic compounds and solvents, reducing diagnostic time from minutes to seconds while maintaining complete diagnostic information through multi-analyte detection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables continuous monitoring of acidosis risk by analyzing breath samples obtained during routine animal handling, allowing for ongoing assessment of rumen health status without interrupting normal farm operations or requiring dedicated diagnostic time

Inventive Principle:

Principle #20Continuity of useful action

AI summary

Embodiments include example systems, devices, and methods for solvent analysis and biological sample analysis, and for analyzing biological samples for solvents associated with health status related to ruminant acidosis, and for on-farm identification of acidosis in ruminants. In certain aspects, acidosis is detected via measurement of solvents and other volatile chemicals present in the ruminants. Embodiments include methods and systems of diagnosing a state of health of an animal by receiving a sample of a bodily fluid or gas from an oral or nasal cavity of the animal, measuring a quantity of at least one of an identified solvent or an identified gas in the sample, and determining a state of health associated with the animal based on the quantity of the identified solvent.
