Pet Training Harness With Guided Control Line for Humane Pulling Control

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pet training devices, such as choker collars and metal spike collars, cause discomfort or pain to pets to discourage pulling on a leash, which is considered inhumane by many pet owners.

Innovation Solution

A pet training harness with a control line system that translates through a guide, connecting to a collar and leash, applies downward force on the pet's neck to discourage pulling by redirecting the head downwards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If choker collars or metal spike collars are used to discourage pulling, then training effectiveness is improved, but pet comfort and welfare deteriorate

Engineering Contradiction:

Improvetraining effectivenessVSAvoidpet discomfort and choking

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful pulling force into a beneficial training mechanism by using a control line that translates through a guide. When the pet pulls, the control line translates through the guide, causing the collar to rotate and the leash to redirect downward, transforming the harmful pulling action into a useful head-redirection training effect without causing pain or choking.

Inventive Principle:

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

Solution Approach 2:

The control line and guide mechanism serve as intermediaries between the pet's pulling force and the training response. Instead of directly applying pain or pressure to the neck, the system uses the control line translating through the guide to create a mechanical advantage that redirects the leash downward, providing a humane intermediary mechanism that achieves training goals without harmful direct contact.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If traditional collars are used to control pulling, then leash control is improved, but airway obstruction and neck injury risk increase

Engineering Contradiction:

Improveleash controlVSAvoidairway obstruction and neck injury

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The system converts the harmful effect of neck pressure into a beneficial training mechanism. Instead of allowing the collar to cinch down and obstruct the airway, the control line translating through the guide converts any pulling force into collar rotation and leash redirection, transforming potentially harmful neck pressure into useful head-direction control.

Inventive Principle:

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

Solution Approach 2:

The patent replaces the traditional mechanical collar system that relies on pressure and friction with a new mechanical system based on translation and rotation. The control line translating through the guide replaces the direct pressure mechanism, creating a new mechanical pathway that achieves leash control without the harmful effects of traditional collar systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If control line translates through guide to redirect head downward, then humane training is achieved, but device complexity increases

Engineering Contradiction:

Improvepet welfare and comfortVSAvoidharness structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system is segmented into distinct functional components: the harness assembly, the control line, the guide mechanism, and the collar. This segmentation allows each component to perform its specific function independently, making the overall complex system manageable and maintainable while achieving the humane training goal through the coordinated interaction of these separate parts.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The guide mechanism serves as an intermediary component that manages the complexity by providing a structured pathway for the control line. This intermediary element simplifies the interaction between the translating control line and the rotating collar, organizing the mechanical complexity into a clear, manageable sequence of actions that achieves humane training效果.

Inventive Principle:

Principle #24Intermediary (Mediator)
