Quadrupedal Animal Harness With Distributed Restraint for Escape Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing harnesses for quadrupedal animals like dogs either cause neck injuries due to pressure concentration or allow the animal to break free, posing risks of escape or entanglement.
Innovation Solution
A harness design with multiple straps positioned across the chest, shoulders, and back, allowing for reduced pressure points and secure attachment points at the neck and croup, preventing escape while maintaining mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a collar is used to restrain or identify a dog, then the animal can be controlled and identified, but the neck of the animal may become injured
Solution Approach 1:
The harness divides the restraint function into multiple separate straps (first strap, second strap, third strap, fourth strap) that are distributed across different body parts (neck, chest, abdomen, croup), rather than using a single collar that concentrates all restraint force on the neck. This segmentation of the restraint system eliminates neck injury while maintaining control capability.
2Object-affected harmful factors
If a harness spreads the pressure across the chest, shoulders and back, then the risk of injury to the neck is reduced, but the shoulder movement of the animal may be restricted
Solution Approach 1:
The harness applies different functional characteristics to different straps: the first and second straps extend from the neck across the chest to the croup (providing restraint and pressure distribution), while the third and fourth straps extend from the chest below the abdomen to the croup (providing abdominal and lower body support). This local differentiation allows the harness to protect the neck without unnecessarily restricting shoulder movement, as the chest-crossing straps are positioned to avoid interfering with arm articulation.
3Ease of operation
If a less restrictive harness is used, then the shoulder movement of the animal is improved, but the animal may break free from the harness and run away
Solution Approach 1:
The harness uses multiple separate straps connected at multiple points (first connection point at the neck, second connection point at the croup, third connection point at the chest) to create a distributed restraint system. This segmentation provides multiple attachment points that work together to prevent escape while maintaining comfort and mobility, addressing both reliability and ease of operation requirements simultaneously.
Solution Approach 2:
The harness combines multiple straps (first, second, third, and fourth straps) that are connected to one another at multiple connection points to form an integrated restraint system. This merging of multiple restraint elements creates a cohesive system that provides both secure attachment and comfort, preventing the animal from breaking free while maintaining natural movement.

AI summary
A harness for a quadrupedal animal, such as a dog, comprising: a first strap, a second strap, a third strap, and a fourth strap, wherein the first strap, the second strap, the third strap, and the fourth strap are connected to one another at a first connection point, and wherein the first strap, the second strap, the third strap, and the fourth strap are connected to one another at, a second connection point, and wherein the first strap, the second strap, the third strap, and the fourth strap extend from the first connection point to the second connection point, wherein the first connection point is configured to, or arranged to, be positioned at a neck, or between the nape and shoulders, of the animal.
