Pet Harness Stress Distribution via Chest Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet harnesses can cause choking and discomfort by applying stress directly to a pet's neck when a leash is pulled, leading to potential harm and discomfort.
Innovation Solution
A non-choking harness design that distributes stress across the pet's chest area, featuring a body part with adjustable straps and a connection system that includes D-rings and Velcro straps to ensure a comfortable fit and prevent neck constriction, made from breathable and elastic mesh-like polyester material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional collar or harness is used to connect a leash to a pet, then the pet can be controlled and walked, but stress is concentrated on the pet's neck causing choking and discomfort
Solution Approach 1:
The harness is divided into multiple functional components: a collar band for neck attachment, a torso band for chest coverage, and connection bands linking them. This segmentation distributes the stress from the leash across multiple body parts (chest and shoulders) rather than concentrating it on the neck, thereby maintaining leash control while eliminating choking hazards.
Solution Approach 2:
The invention transitions from a one-dimensional neck collar to a two-dimensional chest-based harness system. By positioning the primary stress-distributing structure (torso band) across the chest area and connecting it to the neck via the collar band, the system redirects forces from the vertical neck axis to the horizontal chest plane, effectively dispersing stress away from vulnerable neck structures.
2Ease of manufacture
If a conventional uniform-width harness is used, then the structure is simple and easy to manufacture, but it is uncomfortable for the pet and does not distribute stress evenly
Solution Approach 1:
Different portions of the harness are designed with different widths and padding characteristics to match the anatomical features of the pet's body. The torso band is wider to distribute stress across the chest, while the collar band is narrower for neck comfort. Strategic padding is applied at pressure points where the harness contacts the pet's body, providing comfort without complicating the overall manufacturing process.
3Reliability
If the harness is designed to fit securely around the pet's neck and torso, then control is improved, but the harness becomes difficult to put on and take off
Solution Approach 1:
The harness incorporates adjustable straps with buckles or slide mechanisms that allow the fit to be dynamically modified. These adjustable components enable the harness to be easily put on and taken off by loosening the straps, while still providing a secure and customized fit when fastened. The adjustability feature maintains reliability across different pet sizes and harness configurations without compromising ease of operation.

AI summary
A non-choking harness for a pet which evenly distributes stress throughout the chest area and away from the neck area of the pet when the leash is pulled to prevent choking. A center portion of the body part substantially covers the chest area of the pet. The two neck ends are configured to wrap around a neck of the pet and the two torso ends are configured to wrap around a torso of the pet. The adjustable strap removably connects a first torso end to a second torso end, and adjusts the size of the torso opening to provide a comfortable fit. The connection part is configured to removably connect to the two neck ends, removably connect to the adjustable strap; and to adjust the size of the neck opening. The non-choking harness completely opens up for easy access in fitting the pet.
