Dog Collar Lever Arm for Rear Neck Pressure Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog collars often cause aggressive or defensive responses due to 'choking' pressure on the neck, failing to provide a gentle and comfortable correction for leash pulling issues, and require complex mechanical linkages or springs for correction.
Innovation Solution
A contact lever attachment to dog collars that applies pressure to the rear neck using a rotationally displaceable lever arm with a soft protective cover, eliminating the need for springs and complex mechanisms, and allowing adjustable pressure through multiple leash attachment points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dog collars apply choking pressure to the neck to correct leash pulling, then correction effectiveness is improved, but the dog experiences aggressive or defensive responses and discomfort
Solution Approach 1:
The collar is divided into multiple contact points around the neck circumference, with distributed pressure application rather than concentrated choking pressure. Multiple contact points engage the dog's fur and skin at different locations to provide gentle guidance without triggering defensive responses.
Solution Approach 2:
Different portions of the collar have different functions: some contact points provide gentle guidance while others provide stronger correction only when necessary. The collar applies varying degrees of pressure at different locations based on the dog's pulling behavior, allowing effective correction without overall choking pressure.
2Reliability
If collars use complex mechanical linkages or springs to provide correction, then correction mechanism reliability is improved, but device complexity increases
Solution Approach 1:
The collar automatically adjusts and applies correction without requiring external power sources, complex control systems, or maintenance. The mechanical design self-regulates based on the dog's pulling force, eliminating the need for batteries, motors, or electronic components that would increase complexity.
Solution Approach 2:
Complex mechanical linkages, springs, and other complicated correction mechanisms are removed from the design. The invention uses a simplified structure that relies on basic mechanical principles rather than complex moving parts, reducing maintenance needs and improving reliability.
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 solution provides a gentle and comfortable correction that reinforces natural canine behavior, ensuring the dog's safety and effectively addressing leash restraint issues without causing skin abrasion or aggressive responses.
Implementation Method 1
The lever arm has a first end extending beyond a circumferential edge of the collar segment and is rotationally displaceable about the circumferential direction to contact a rear of the neck of the animal when the animal pulls on a leash connected to the lever arm
Implementation Method 2
The body contact prong can be covered in a soft safety material such as foam, rubber or elastomer, which allows the dog to feel the necessary pressure on the body, such as dorsal side of its neck, recognize this as a signal to correct behavior, all while keeping the skin safe from abrasion

AI summary
A correction device includes a collar segment for extending in a circumferential direction around an animal's neck. A lever arm affixed to the collar segment. The lever arm has an extent transverse to the circumferential direction. The lever arm has a first end extending beyond a circumferential edge of the collar segment and is rotationally displaceable about the circumferential direction to contact a rear of the neck of the animal when the animal pulls on a leash connected to the lever arm. The lever arm has a connection position opposite the first end for attachment of the leash.
