Cinching Mechanism for Animal Harnesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal restraint systems, such as harnesses and collars, often shift or rotate when subjected to pulling forces, reducing control over quadrupedal animals and causing discomfort due to uneven tension distribution.
Innovation Solution
A limited-slip cinching mechanism that maintains the centered position of the cinching mechanism on the animal's body, utilizing a cinching strap with connectors that draw together when tension is applied, ensuring consistent force transmission and preventing shifting or rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional harnesses and collars are used with simple leash attachment rings, then the device complexity is low, but the control precision and stability deteriorate because the attachment point shifts or rotates under pulling forces
Solution Approach 1:
The cinching mechanism incorporates a dynamic strap system that automatically adjusts and tightens around the animal's chest when force is applied. The strap transitions from a loose state to a tightened state, dynamically adapting to the applied load while maintaining the attachment point's centered position through the cinching action of the strap around the chest.
2Stability of the object's composition
If traditional harnesses allow free movement of the attachment ring, then the ease of operation is high, but the stability of the object's composition deteriorates as the attachment point shifts or rotates across the animal's body
Solution Approach 1:
The cinching mechanism applies a preliminary counteracting force through the strap that wraps around the animal's chest. When the animal pulls or lunges, the strap automatically tightens to counteract the shifting or rotating tendency of the attachment point, maintaining its centered position through this preliminary anti-action.
3Reliability
If the cinching mechanism allows substantial shifting under force, then the adaptability is high, but the reliability of force transmission deteriorates
Solution Approach 1:
The harness is segmented into distinct functional components: the torso strap assembly, the chest strap assembly, and the cinching mechanism. This segmentation allows the cinching mechanism to independently maintain the attachment point's position while the other components provide adaptability for different animal sizes and shapes.

AI summary
The present technology generally relates to animal restraint systems with cinching mechanisms and associated devices and methods. A restraint system, such as a harness for a dog, in accordance with the present technology can include a back strap, a sternum strap, a chest strap assembly, and a cinching mechanism coupled to the chest strap assembly. When an animal or person pulls on a free-end portion of a cinching strap, the cinching mechanism draws opposing sides of the chest strap assembly closer together and, thereby, tightens the harness across the chest of the animal. Cinching mechanisms in accordance with the present technology avoid substantial shifting or rotation of the harness on the neck or torso of the animal in response to a lunging, pulling, tugging, or other force.
