Estrus Detection Device with LoRaWAN Long-Range Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing estrus detection systems for animals are inadequate as they fail to reliably monitor standing mounts, provide accurate data transmission over long distances, and integrate with machine learning models for predictive analytics, especially in challenging environments and tropical climates.
Innovation Solution
A narrow, arched end device with a LoRa radio using the LoRaWAN protocol for data transmission, securely attached to the animal's tailhead, collects and stores data on standing mounts, motion, temperature, and other factors, and uses machine learning methods like neural nets for predictive estrus detection, allowing data to be stored and transmitted even when out of range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visual indication systems are used for estrus detection, then the device structure is simple, but the data transmission distance is limited and requires viewer proximity
Solution Approach 1:
The patent replaces visual indication systems with radio frequency communication systems. The estrus detection device transmits data wirelessly via radio waves instead of requiring visual line-of-sight, enabling remote monitoring without increasing mechanical complexity of the core detection mechanism.
2Loss of information
If standard radio communication systems are used, then data transmission capability is provided, but the devices are unable to reliably maintain adhesion to the animal
Solution Approach 1:
The patent employs composite attachment mechanisms combining adhesive materials with mechanical anchoring features. The device integrates radio frequency communication capabilities with robust multi-material attachment systems that ensure reliable adhesion to animal surfaces during movement and mounting activities.
3Measurement precision
If motion and temperature monitoring are added to determine standing mount, then measurement comprehensiveness is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple sensing functions (motion detection, temperature monitoring, standing mount detection) into a single unified estrus detection device. The system uses multi-functional sensors and processing capabilities to comprehensively monitor various physiological parameters simultaneously without requiring separate dedicated devices for each measurement.
4Length of stationary object
If LoRa radio transmission is implemented, then long-range data transmission is achieved, but power consumption increases
Solution Approach 1:
The patent implements periodic transmission cycles where the LoRa radio transmits data at intervals rather than continuously. The system monitors estrus parameters and transmits updates periodically or event-driven, reducing overall power consumption while maintaining long-range communication capability when data needs to be reported.
5Loss of information
If data storage capability is added for offline data retention, then data continuity is improved, but device memory requirements increase
Solution Approach 1:
The patent extracts and stores only essential estrus detection data parameters locally in device memory, while transmitting detailed datasets to remote servers or cloud platforms. The local storage retains critical summary information and timestamps for offline periods, reducing on-device memory requirements while maintaining data continuity through selective local caching.
