Solution Overview

Problem

Existing bark stop devices often incorrectly detect loud external sounds as barking, leading to unnecessary stimulation and potential harm to pets, as they rely on simple audio judgment rather than precise vibration detection.

Innovation Solution

A bark detection method using an induction coil within a magnetic field, mounted on a pet's neck, which generates an induction current based on throat vibrations during barking, and a microprocessor for accurate judgment, combined with a vibration or ultrasonic warning system to stop barking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If audio judgment is used to detect barking, then the device can respond to loud sounds, but the detection accuracy deteriorates leading to erroneous judgments

Engineering Contradiction:

Improvebarking detection accuracyVSAvoidfalse alarm rate

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent replaces the acoustic detection system with an electromagnetic detection system. An induction coil detects throat vibrations during barking by measuring changes in magnetic flux caused by the vibration of a magnet attached to the throat. This mechanical-vibration-based detection method is more accurate and reliable than audio judgment, as it directly measures the physical act of barking rather than relying on sound wave analysis.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnet as an intermediary element attached to the pet's throat. The magnet converts throat vibrations into magnetic field variations that can be detected by the induction coil. This intermediary mechanism provides a direct physical coupling between the barking action and the detection system, eliminating the ambiguities inherent in audio-based detection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If simple audio detection is used, then the device complexity is reduced, but the control precision deteriorates

Engineering Contradiction:

Solution Approach 1:

The patent replaces complex audio processing circuits with a simpler electromagnetic induction system. The induction coil and magnet configuration provides direct vibration detection without requiring complex signal processing, filtering, or pattern recognition algorithms needed for accurate audio-based barking detection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

Solution Approach 1:

The patent replaces audio-based judgment with direct vibration detection through electromagnetic induction. The system simply detects whether the induction coil generates a voltage signal corresponding to throat vibrations, providing reliable and unambiguous barking detection without the complexity of audio analysis while maintaining ease of operation.

AI summary

The invention discloses a bark detection method. An induction coil located in a magnetic field is arranged in a bark stop device worn on a head and neck part of a pet dog, and is configured to monitor a violent vibration action of a throat part of the pet dog. Violent vibration of the throat part of the pet dog during barking causes relative displacement between the magnetic field and the induction coil, so that the induction coil cuts magnetic lines of force of the magnetic field and generates an induction current. The induction current is collected and compared to judge whether the pet dog is barking or not. By using the induction current generated by the induction coil as a basis for judging whether the pet dog is barking or not, judging accuracy can be improved, and erroneous judgment is reduced to a great degree. The invention also discloses a bark detection device and a bark stop device with the device.
