Sliding Strap Animal Restraint for Neck Trauma Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Animal restraints, such as collars and harnesses, can cause trauma to a dog's neck structures due to concentrated force distribution, leading to injuries like tracheal collapse and arthritis, as they often rely on fixed fastening points that rotate around the neck, causing unnatural gait and strain.
Innovation Solution
An animal restraint design featuring a strap that slides around a track housing with impact-resistant padding, distributing pulling forces and maintaining proper anatomical alignment, and a leash guide with a sliding leash attachment ring to reduce friction and prevent misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed fastening point is used in traditional restraints, then the structure is simple, but the restraint rotates around the neck causing unnatural gait and strain
Solution Approach 1:
The patent applies the dynamics principle by making the fastening point movable along the strap rather than fixed. The leash attachment ring can slide freely along the strap length, allowing the restraint to dynamically adjust its configuration as the dog moves and pulls, preventing rotation around the neck and maintaining natural gait.
2Object-affected harmful factors
If a strap goes around the neck with a fixed attachment point, then the restraint is easy to manufacture, but concentrated force causes trauma to neck structures
Solution Approach 1:
The dynamic fastening point allows the restraint to redistribute pulling forces along the strap length rather than concentrating them at a single fixed attachment point. As the dog pulls, the attachment ring slides to optimize force distribution, reducing trauma to neck structures while maintaining simple restraint construction.
3Stability of the object's composition
If the fastening point is fixed at one location, then the device is simple, but pulling force causes the restraint to rotate and misalign anatomical structures
Solution Approach 1:
The movable fastening point maintains stable anatomical alignment by allowing the attachment ring to slide along the strap, preventing rotation of the restraint around the neck. This dynamic adjustment keeps the restraint properly aligned with anatomical structures during pulling forces without requiring complex stabilization mechanisms.

AI summary
An animal restraint is disclosed for mitigating collar trauma to critical neck structures of an animal. The animal restraint includes a track housing defining an exterior surface and an interior surface. A plurality of loops are positioned on the exterior surface of the track housing. A strap is threaded through the loops, and is adapted to slide around the exterior surface of the track housing from a pulling force on the animal restraint. The strap includes a leash attachment ring adapted for attachment to a leash. Impact resistant padding is attached to the interior surface of the track housing, and the sliding movement of the strap maintains a proper positioning of the impact resistant padding over corresponding anatomical neck structures of an animal.
