Spraying Leash Assembly Integrating Liquid Spray and Audible Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog leash devices fail to effectively deter barking by solely relying on liquid sprayers, as they do not incorporate a distracting audible sound component.
Innovation Solution
A leash device integrating a retractable leash, a hollow reservoir for non-toxic liquid, a spray nozzle, a light emitter, and a speaker within a handle, which can be gripped for carrying, to distract the dog from barking by spraying liquid and emitting an audible sound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a liquid sprayer is integrated into the leash device, then the dog is distracted from barking by the liquid spray, but the device lacks auditory distraction capability
Solution Approach 1:
The patent combines a liquid sprayer and a speaker into a single leash device, integrating two different distraction mechanisms (visual/tactile spray and auditory sound) into one unified device. This merging approach enhances the versatility and effectiveness of the leash while managing the complexity through integrated design.
Solution Approach 2:
The leash device is designed to perform multiple functions: it can spray liquid onto the dog and emit audible sounds through the speaker. This multi-functionality allows the single device to address barking behavior through multiple sensory channels, making it more adaptable and effective than single-function devices.
2Reliability
If only a liquid sprayer is used to deter barking, then the device structure remains simple, but the effectiveness in deterring barking is insufficient
Solution Approach 1:
The patent merges a liquid sprayer and a speaker into one integrated leash device, combining two different distraction mechanisms (visual/tactile and auditory) to enhance the reliability of barking deterrence while managing the added complexity through unified design.
Solution Approach 2:
The leash device acts as an intermediary between the owner and the dog, providing multiple forms of distraction (spray and sound) that mediate the interaction and help control barking behavior more effectively than a single mechanism could achieve.
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 device effectively trains dogs to avoid barking by combining visual and auditory distractions, enhancing the leash's ability to manage unwanted barking behavior during walks.
Implementation Method 1
A spray nozzle is integrated into the reservoir to spray the fluid outwardly from the reservoir onto the dog thereby distracting the dog from barking
Implementation Method 2
A light emitter is coupled to the reservoir to emit light outwardly therefrom
Implementation Method 3
A speaker is integrated into the handle for emitting an audible sound outwardly therefrom to distract the dog from barking

AI summary
A spraying leash assembly includes a leash unit that has a retractable leash such that the leash can be attached to a collar of a dog for walking the dog. A reservoir is coupled to the leash unit and the reservoir is hollow to contain a liquid. A spray nozzle is integrated into the reservoir to spray the fluid outwardly from the reservoir onto the dog thereby distracting the dog from barking. A light emitter is coupled to the reservoir to emit light. A handle is coupled to the reservoir and the handle can be gripped for carrying the reservoir and the leash unit. A speaker is integrated into the handle for emitting an audible sound to distract the dog from barking.
