Pet Spray Training System Using Bark Sensor and Motor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pet training systems for controlling excessive barking, such as collar-mounted pressurized spray canisters, are complex to produce in high volume and often require refillable tanks or pump mechanisms prone to leakage, and many pet owners are hesitant to use electrical stimuli on small or frail pets.
Innovation Solution
A portable pet spray training system that uses a pre-pressurized canister with an electrical motor module to release a bark deterrent fluid through a spray nozzle, operated by a sensor and motor module that responds to a dog's barking, allowing for remote activation and easy canister replacement, without the need for a refillable tank or pump mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collar-mounted pressurized spray canister is used to control barking, then the barking control function is achieved, but the device complexity increases and manufacturing becomes difficult in high volume
Solution Approach 1:
The device is divided into separate functional modules: a collar unit with sensor and electronics, and a separate pressurized canister assembly. This segmentation simplifies manufacturing of each component while maintaining the integrated barking control function.
Solution Approach 2:
The pressurized spray mechanism is extracted as a separate replaceable canister from the collar unit. This allows the collar electronics to be produced independently in high volume without the complexity of integrating pressurized systems, while the canister handles the spray delivery function.
2Duration of action of moving object
If a refillable tank or pump mechanism is used, then the spray function is maintained, but leakage issues occur and reliability decreases
Solution Approach 1:
The canister is pre-filled and pre-pressurized at the factory before being sealed and attached to the collar. This preliminary action ensures the spray system is ready for immediate use without requiring user refilling or pump operation, eliminating leakage risks associated with user handling of refillable tanks.
Solution Approach 2:
The canister is designed as a disposable or replaceable component rather than a permanent refillable tank. Once the spray is depleted, the entire canister is replaced rather than refilled, eliminating the need for user-accessible refill mechanisms and associated leakage problems.
3Reliability
If electrical stimuli are applied to control barking, then the training effect is achieved, but pet owners are hesitant to use it on small or frail pets
Solution Approach 1:
A spray medium (such as compressed air or inert gas) is introduced as an intermediary between the electrical sensing system and the dog. The sensor detects barking and triggers the spray mechanism, which delivers a physical stimulus without direct electrical contact with the pet's body, addressing owner concerns about electrical stimuli on small or frail animals.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively discourages barking by releasing a deterrent fluid when the dog barks, providing a humane and efficient solution for pet owners, with the ability to remotely control the device and easily replace the canister, addressing the complexity and leakage issues of existing systems.
Implementation Method 1
The sensor is configured to receive an input (such as sound frequencies), and to generate electrical signals in response
Implementation Method 2
the valve releases a spray of the fluid from a tank in the region of the head of the dog
Data Source
AI summary
An pet spray training system is provided. The system includes a sound, vibration or motion sensor that is configured to generate electrical signals in response to an occurrence. The system may include a filter, which is tuned to recognize a dog barking event, and generate an electrical signal in response to recognizing an input signal indicative of a dog's bark. The system further includes a removably pressurized gas reservoir that holds a deterrent fluid under pressure. The system additionally comprises a motor module configured to rotate a shaft in response to the electrical signal from the filter. The canister has a spray nozzle for releasing fluid that affects the dog's senses. In response to rotating the shaft, the spray nozzle is depressed.
