Single-Point Pet Harness Assembly for Quick Release Under Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet harness systems for vehicles are cumbersome, limit animal mobility, and lack a quick release mechanism, posing a risk of trapping the animal under high impact forces.
Innovation Solution
A harness assembly with a single point attachment, featuring a continuous skeletal structure of multiple webbing straps secured by steel O-rings, looped stitching, and quick release coupling means, allowing for secure restraint and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple buckles and interconnecting webbing straps are used to restrain the animal, then the animal's safety under high impact forces is improved, but the device complexity increases and the animal's mobility is limited
Solution Approach 1:
The harness is divided into multiple webbing straps (neck strap, chest strap, back strap, side straps) that are interconnected at specific points. This segmentation allows the force to be distributed across multiple components while maintaining a relatively simple overall structure with only two buckles needed for adjustment and release.
Solution Approach 2:
The webbing straps are pre-configured with loops and attachment points positioned to optimize safety during high impact events. The D-ring is pre-positioned at the optimal location on the back strap, and the webbing is routed through the harness in advance to ensure proper force distribution during restraint.
2Ease of operation
If multiple buckles are used for adjustment and separation, then the ease of operation is improved, but the reliability decreases under high impact forces due to potential failure points
Solution Approach 1:
The invention extracts and eliminates unnecessary buckles from the harness system, retaining only two essential buckles for adjustment and release. This reduction minimizes potential failure points under high impact forces while preserving the necessary adjustability and ease of operation through the retained buckles and quick-release mechanism.
3Ease of operation
If a conventional three-point seatbelt is used to restrain the animal, then the ease of operation is improved, but the animal's mobility is limited and the animal may become tangled
Solution Approach 1:
The harness employs dynamic webbing straps that can adjust and move with the animal's movements, providing restraint while maintaining mobility. The webbing material and construction allow for elastic deformation and flexibility, enabling the animal to move naturally without becoming tangled, unlike rigid conventional seatbelts.
4Ease of operation
If looping means is used to engage the seat belt, then the ease of operation is improved, but the reliability decreases as the animal may be trapped under high impact forces
Solution Approach 1:
The harness incorporates a quick-release mechanism that is pre-configured and readily accessible, allowing the animal to be quickly freed in emergency situations. The release mechanism is positioned and designed in advance to enable rapid operation under stress, preventing the animal from being trapped during high impact events.

AI summary
A harness assembly with a single point attachment point means for everyday use, such as with a leash, and which is capable for safely and securely restraining an animal within a vehicle. The harness assembly comprises multiple webbing straps interconnected by at least two O-rings and several stitching arrangements to form a skeletal structure and a D-ring securely connected to the skeletal structure to provide function for a single point attachment. More particularly, the multiple webbing straps include a pair of neck straps, a chest strap, a back strap, a lateral connecting strap and a rear connecting strap. Complementing members are provided at the ends of the lateral strap and back strap to form quick release buckles which are capable of being disengaged even when the lateral and back straps are under tension such as the result of a high impact force.
