Barking Prohibition Device Multi-Modal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barking prohibition devices for pets struggle to accurately identify which dog is barking among multiple dogs, leading to false triggering and unnecessary silencing of quiet dogs.
Innovation Solution
A control method and device that detect dog barking sounds and vibration characteristics, including head shaking and larynx vibrations, to determine if a preset noise or audio threshold is met, ensuring accurate identification and triggering of the barking prohibition action only when specific criteria are satisfied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If audio detection alone is used to identify barking, then the device complexity is reduced, but the measurement precision of barking identification deteriorates
Solution Approach 1:
The patent combines audio detection and vibration detection into a unified barking identification system. The audio detection module captures barking sounds while the vibration detection module captures head shaking vibrations, and both signals are processed together to determine whether the dog is barking. This merging of multiple detection methods resolves the contradiction by maintaining low device complexity while significantly improving measurement precision through multi-modal signal correlation.
2Measurement precision
If multiple detection methods are used to improve barking identification accuracy, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The patent implements a control device that performs multiple functions using integrated sensors: the audio detection module handles sound signal acquisition, the vibration detection module handles mechanical vibration acquisition, and the processing unit correlates both signals to identify barking. This multi-functional approach improves measurement precision without proportionally increasing device complexity by making each component serve multiple purposes in the barking identification process.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Accurately identifies the barking dog and triggers the barking prohibition action only when necessary, preventing false silencing of quiet dogs and ensuring effective bark suppression.
Implementation Method 1
detecting vibration characteristics of the dog barking sound, where the vibration characteristics of the dog barking sound include a head shaking characteristic and a dog-larynx vibration characteristic during dog barking
Implementation Method 2
detecting a dog barking sound

AI summary
A control method for barking prohibition in a barking prohibition piece. This method includes: detecting a dog barking sound; detecting vibration characteristics of the dog barking sound; determining whether the dog barking sound has reached a preset noise level or whether the audio characteristic of dog barking has reached a preset audio characteristic; determining whether the detected vibration characteristics during dog barking include a head shaking characteristic and a dog-larynx vibration characteristic; and when the dog barking sound has reached the preset noise level or the audio characteristic of dog barking has reached the preset audio characteristic and the detected vibration characteristics during dog barking include the head shaking characteristic and the dog-larynx vibration characteristic, determining that the dog wearing the barking prohibition piece is barking and that a predefined barking prohibition trigger condition is satisfied, and sending a barking prohibition action to the dog wearing the barking prohibition piece.
