Pivotable Pet Harness Frame with Spring Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal harnesses that encircle the neck and body are cumbersome, time-consuming to put on, and can cause injury to the animal by applying pressure on the neck and airway, and the leash ring is often difficult to locate and attach.
Innovation Solution
A two-part pivotable frame with spring hinges and adjustable straps that encircles the animal's body, allowing for quick and safe restraint without choking, featuring a leash clip positioned behind the frame for easy attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a harness encircles the animal's neck and body with multiple straps and buckles, then the restraint is secure and reliable, but the device becomes cumbersome and time-consuming to install
Solution Approach 1:
The harness is divided into two separate frame members (first and second frame members) that can be independently manipulated. Each frame member has fingers that can be opened and closed independently, allowing for simplified installation while maintaining secure restraint through the coordinated action of both segments
Solution Approach 2:
The frame members are made dynamically adjustable through spring hinges and biasing springs that allow the fingers to be opened for installation and then automatically closed for secure restraint. The spring-loaded mechanism enables quick transition between open (installation) and closed (restraint) states
2Adaptability or versatility
If traditional harnesses use multiple straps and buckles to fit different animals, then the harness can accommodate various sizes, but the installation time increases significantly
Solution Approach 1:
The frame members incorporate adjustable fingers with spring hinges that can be dynamically positioned to accommodate different animal sizes. The biasing springs allow the fingers to be opened wide for easy installation on larger animals and then automatically close to provide secure restraint, eliminating the need for time-consuming manual adjustment of multiple buckles
Solution Approach 2:
The spring-loaded mechanism provides self-adjusting functionality where the biasing springs automatically close the fingers after installation, reducing the need for manual adjustment and minimizing installation time across different animal sizes
3Ease of operation
If a neck collar is used for simple leash attachment, then the harness is quick to put on, but it causes injury to the animal's wind pipe by putting pressure on the neck
Solution Approach 1:
The harmful function of neck pressure is completely removed from the design. The harness encircles only the body behind the front legs, extracting the restraint function away from the neck area entirely. The leash ring is positioned on the back of the harness, eliminating any risk of airway obstruction while maintaining secure restraint capability
Solution Approach 2:
The body-encircling harness acts as an intermediary between the leash and the animal, distributing restraint forces across the broader body area rather than concentrating them on the narrow neck. This intermediary structure provides secure control while protecting the vulnerable airway
4Device complexity
If the leash ring is positioned downward under the animal's neck on traditional collars, then the collar structure is simple, but the leash becomes difficult to locate and attach
Solution Approach 1:
The leash ring is repositioned from the traditional downward position under the neck to an upward position on the back of the harness. This dimensional relocation places the leash attachment point in a more accessible location that is easier to locate and attach to, while maintaining the simplicity of the overall harness structure

AI summary
A animal restraint harness having a two part pivotable frame having a set of fingers or arms extended therefrom to encircle or saddle an animal body, a spring hinge to force the fingers together, tabs or opening handles to separate the fingers, one or more harness straps, and a leash clip positioned thereon the frame and, thus such harness enables a single person to quickly and/or efficiently place the harness assembly on the animal using one hand and such harness enables safe restraint of the animal without causing the animal to choke or wheeze.
