Solution Overview

Problem

Current methods for detecting hoof diseases and leg anomalies in livestock are invasive, unreliable, and difficult to maintain, as they require internal devices that cannot be removed or repaired.

Innovation Solution

A non-invasive sensor arrangement attached to the animal's legs, featuring acceleration and inclination sensors that measure and process time-dependent data, allowing for accurate detection of musculoskeletal system anomalies through data comparison with pre-stored profiles, with optional external data processing and visual indicators for easy monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an internal device is implanted in the animal for continuous monitoring, then the reliability of disease detection is improved, but the animal suffers internal burden and the device cannot be removed or repaired

Engineering Contradiction:
Improvedisease detection reliabilityVSAvoidinternal burden on animal
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The monitoring system is divided into separate components: a removable sensor unit attached to the animal's exterior and a separate data processing system. This segmentation allows the sensor to be detached and replaced without internal surgery, eliminating the need for permanent implantation while maintaining monitoring capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An external data processing system acts as an intermediary between the sensor and the final analysis. The sensor collects data and transmits it externally, where processing and evaluation occur. This intermediary approach enables reliable disease detection through continuous monitoring without requiring the sensor to be permanently implanted inside the animal.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Duration of action of moving object

If an internal device is permanently implanted in the animal, then continuous monitoring capability is improved, but the device becomes permanently inaccessible and cannot be maintained

Engineering Contradiction:
Improvecontinuous monitoring capabilityVSAvoiddevice accessibility for maintenance
Core Design Contradiction:
Duration of action of moving objectVSEase of repair

Solution Approach 1:

The system is segmented into a removable sensor component and a separate processing system. The sensor unit can be detached, maintained, or replaced by veterinary personnel without requiring animal surgery or complex procedures, ensuring continuous monitoring capability while maintaining ease of repair.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor unit is designed to be self-contained with internal power supply and data storage, allowing it to function autonomously during attachment. The unit can be easily removed and replaced by personnel without specialized training, enabling simple maintenance while maintaining continuous monitoring through regular sensor replacement.

Inventive Principle:
Principle #25Self-service

3Reliability

If optical measurement of back shape changes is used to detect gait abnormalities, then the ability to detect hoof diseases is improved, but the evaluation becomes very complicated and highly error-prone

Engineering Contradiction:
Improvehoof disease detection capabilityVSAvoidevaluation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The complex optical measurement and evaluation system is replaced with a mechanical sensor system that directly measures acceleration and movement parameters. The sensor unit contains accelerometers and other sensors that mechanically detect gait abnormalities and transmit data externally for simplified processing, replacing complicated optical evaluation with straightforward mechanical measurement and digital analysis.

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