Solution Overview

Problem

Conventional dog training devices often require excessive force and can cause discomfort to dogs, and they are typically designed for specific leashes or collars, limiting their usability.

Innovation Solution

A training device with a strap attachable to a dog's front leg, featuring a guide and a detachable mechanism that allows the leash to be passed through, with a hook and loop fastener or adjustable attachment, which releases when excessive force is applied, ensuring the dog's safety and compatibility with conventional leashes and collars.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional choke collars or muzzle collars are used, then the trainer can control the dog, but excessive force is required and excessive discomfort is caused to the dog

Engineering Contradiction:

Improvecontrol effectivenessVSAvoiddiscomfort to dog

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a front-leg attachment device as an intermediary between the dog's body and the leash. This mediator redirects the leash attachment point to the front leg rather than using traditional choke or muzzle collars, thereby maintaining control effectiveness while eliminating the harmful discomfort associated with conventional methods

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The control mechanism is segmented into separate components: a front-leg strap attachment and a guide system. This segmentation allows the leash to be attached at the front leg while using a standard collar, separating the control function from the restraint function and reducing overall discomfort to the dog

Inventive Principle:

Principle #1Segmentation

2Reliability

If conventional training devices are used, then training control is achieved, but custom or specially designed leashes and collars are required that are not usable for other purposes

Engineering Contradiction:

Improvetraining controlVSAvoidusability with conventional leashes and collars

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The front-leg attachment device is designed to work with standard conventional leashes and collars, making it universally compatible. The device adds training control functionality to existing equipment rather than requiring specialized custom-made components, thereby maintaining versatility and adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The front-leg attachment acts as a universal intermediary component that can be combined with various conventional leashes and collars. This mediator interface allows different leash and collar combinations to work together through the standardized front-leg attachment point

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the leash is securely attached to prevent pulling, then control is maintained, but the dog may be injured when excessive force is applied

Engineering Contradiction:

Improvecontrol during pullingVSAvoidinjury risk to dog

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The detachable attachment mechanism at the front leg serves as a pre-planned safety feature. When excessive force is applied during pulling, the attachment automatically detaches, providing beforehand cushioning against potential injury to the dog's neck, spine, or other body parts

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The potential harmful effect of excessive pulling force is converted into a beneficial safety mechanism. The detachable attachment is designed to fail safely under excessive load, transforming the harmful uncontrolled force into a controlled release that protects the dog while maintaining training effectiveness during normal use

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

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 prevents dogs from pulling by reducing leverage and providing a safety mechanism to prevent injury, while allowing for adjustable force settings based on the dog's size and weight, ensuring effective training without causing discomfort.

Implementation Method 1

AI summary

Devices and system are provided that can not only stop a pet from pulling its owner, but to train a pet over time to not pull while being walked on a leash. In an exemplary implementation, a cuff can be wrapped around the highest point of either front leg of a pet, using, for example a hook and loop fastener and running a leash through the sleeve or guide on the outside of the cuff, so that an existing leash can be run from the collar, under the inside of the leg and up to the owner's hand.
