Double Rope Pet Leash With Rotatable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet leashes lack flexibility, particularly for users with multiple pets, as they are designed to connect only one leash fixedly, limiting their usability.
Innovation Solution
A double rope pet leash design featuring a leash body with a rotatable second leash assembly and an open-close assembly, allowing simultaneous connection of two leash ropes, with a first leash assembly forming the boundary of a leash cavity and a second leash assembly within, utilizing a torsion bar and knob for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single-leash design is used, then the structure is simple, but the adaptability is poor for users with multiple pets
Solution Approach 1:
The leash is divided into multiple independent leash assemblies (first leash assembly with first leash rope, second leash assembly with second leash rope) that can be separately managed and connected, allowing one leash device to serve multiple pets simultaneously
Solution Approach 2:
The leash body is designed to accommodate and connect multiple leash assemblies, enabling a single leash device to perform the function of restraining multiple animals, thus expanding its universal applicability
2Ease of operation
If only one leash is fixedly connected, then the structure is simple, but the ease of operation is reduced for users with multiple pets
Solution Approach 1:
The second leash assembly is designed to be rotatably connected to the leash body rather than fixedly connected, allowing dynamic adjustment and flexible operation when connecting multiple leashes, thereby improving ease of operation
Solution Approach 2:
The second leash assembly is nested within the leash cavity when not in use, and can be easily accessed and connected when needed, providing convenient operation for users who need to manage multiple leashes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the simultaneous connection of two leash ropes, expanding application range, simplifying structure, and facilitating easy operation and maintenance, making it suitable for various leash rope shapes and large-scale production.
Implementation Method 1
The open-close assembly includes a knob and a torsion bar that are fixedly connected to each other. The torsion bar is rotatably connected to the leash body. The knob is rotatable to allow the torsion bar to pass through the first leash shaft and be pressed on an inner surface of the leash body.

AI summary
A double rope pet leash includes a leash body. A leash cavity is located in the leash body. A first leash assembly and a second leash assembly are connected to the leash body. The first leash assembly is fixedly connected with the leash body. The second leash assembly is located in the leash cavity and rotatably connected to the leash body. A first leash rope is pressed on the surface of the first leash assembly, and a second leash rope is pressed on the surface of the second leash assembly. The double rope pet leash further includes an open-close assembly connected to the leash body and capable of opening or closing the leash cavity
