Solution Overview

Problem

Current methods for detecting the preparatory phase of parturition in cattle and horses are invasive, costly, unreliable, and require constant human surveillance, often leading to false alarms and increased risk of infection or animal discomfort.

Innovation Solution

A device attached to the animal's tail measures acceleration along multiple axes, processes these measurements to detect specific physiological and behavioral patterns associated with parturition, and generates a radio signal when the preparatory phase is detected, using low energy consumption and digital communication to ensure autonomy and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If intrusive sensors are introduced into the genital tract to detect parturition, then detection capability is improved, but animal comfort and hygiene deteriorate due to infection risk and irritation

Engineering Contradiction:
Improveparturition detection capabilityVSAvoidinfection risk and animal irritation
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The detection device is extracted from the genital tract and relocated to the tail of the animal. This removes the harmful intrusive element while preserving the ability to detect parturition through alternative means (tail position changes that occur during labor).

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The tail serves as an intermediary element to detect parturition indirectly. Instead of measuring physiological parameters directly in the genital tract, the system uses tail position and movement as a mediator that reflects the animal's labor state without contacting sensitive areas.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If simple tail-mounted inclinometers are used to detect parturition, then device complexity is reduced, but reliability deteriorates due to false alarms from normal animal movements

Engineering Contradiction:
Improvedetection device simplicityVSAvoidparturition detection reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

Multiple detection functions are merged into a single integrated system on the tail. The device combines acceleration sensors, signal processing capabilities, and communication functions to analyze complex movement patterns rather than relying on simple inclination measurement alone.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system incorporates signal processing that analyzes patterns of tail movements over time and provides feedback to distinguish true labor signs from normal movements. The device learns and adapts to the specific animal's movement patterns to reduce false alarms.

Inventive Principle:
Principle #23Feedback
