Pivotable Pet Harness Frame 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 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 encircle 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 traditional harnesses encircle the animal's neck and body with multiple straps and buckles, then the harness provides secure restraint, but the harness becomes cumbersome and time-consuming to install
Solution Approach 1:
The harness is divided into two separate parts: a body harness portion and a head collar portion. These segments can be independently assembled and then connected, allowing for quicker installation while maintaining secure restraint through the distributed structure of multiple connection points
Solution Approach 2:
The body harness and head collar are pre-assembled as separate complete units with all necessary straps and buckles already in place. This preliminary assembly eliminates the need to attach individual components during installation, reducing installation time while preserving the secure multi-point restraint configuration
2Ease of operation
If traditional neck collars are used for restraint, then the harness installation is quick and simple, but the collar applies pressure on the animal's neck and airway causing injury
Solution Approach 1:
The harmful function of neck pressure is extracted from the restraint system by separating the head collar from direct contact with the neck. The head collar is positioned behind the ears and around the muzzle area, removing the airway obstruction problem while maintaining restraint capability through the connected body harness
Solution Approach 2:
The body harness acts as an intermediary structure that distributes restraint forces across the animal's back and chest rather than concentrating them on the neck. This mediator structure transfers the load from the head collar through the body harness, preventing direct pressure on the airway while maintaining effective control
3Device complexity
If the leash ring is positioned downward under the animal's neck, then the collar structure is simple, but the leash becomes difficult to locate and attach
Solution Approach 1:
The leash attachment point is moved from a vertical position under the neck to a horizontal position on the side of the head collar, near the animal's ear. This dimensional relocation makes the attachment point visible and accessible from the side, improving ease of operation while maintaining structural simplicity

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.
