Pivotable Pet Harness With Spring Hinge
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 putting pressure on the neck and airway, and the leash ring is often difficult to locate and attach.
Innovation Solution
A two-part pivotable frame harness with spring hinges, tabs, and adjustable straps that encircle the animal's body, allowing for quick and safe restraint without choking, and featuring a leash clip positioned behind the frame for easy leash attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional harnesses with multiple straps and buckles are used to encircle the animal's neck and body, then the harness provides secure restraint, but the device becomes cumbersome and time-consuming to install
Solution Approach 1:
The harness is divided into a head portion and a body portion that can be independently adjusted and positioned. The head portion includes adjustable head straps that can be independently configured, while the body portion has separate adjustment mechanisms. This segmentation allows for quicker installation by enabling independent adjustment of each portion rather than requiring simultaneous adjustment of multiple interconnected straps and buckles.
2Ease of operation
If traditional neck collars are used for restraint, then the harness is simple to put on, but the leash ring is positioned downward under the neck making it 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 top surface of the head portion. This dimensional relocation in the vertical axis makes the leash ring immediately visible and easily accessible for leash attachment, eliminating the need to search underneath the animal's neck while maintaining simple placement procedures.
3Device complexity
If traditional neck collars are used for restraint, then the harness structure is simple, but tugging on the leash causes injury to the animal's wind pipe by putting pressure on the neck and airway
Solution Approach 1:
The restraint function is extracted from the neck collar and relocated to the head and body portions of the harness. The head portion distributes pressure across the top of the head and ears, while the body portion encircles the torso, completely removing pressure from the neck and airway area. This extraction eliminates the harmful effect while maintaining relatively simple harness structure through independent adjustment mechanisms.
4Adaptability or versatility
If adjustable straps and multiple connection points are added to accommodate different animal sizes, then the harness becomes versatile, but the number of parts and assembly complexity increases
Solution Approach 1:
The head portion and body portion are designed with universal adjustment mechanisms that can accommodate a wide range of animal sizes and shapes. The adjustable head straps and body portion connection points serve multiple functions: they provide size adjustment, positional adjustment, and secure restraint. This multi-functionality reduces the need for separate adjustment mechanisms for each size category, thereby limiting the increase in overall part complexity while maintaining high versatility.

AI summary
A animal restraint adjustable 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.
