Dual-Arm Leash Design for Pet Pulling Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional leashes often lead to pets pulling excessively, which can result in injury or escape, as they tend to walk ahead of their owners, causing strain on the leash and potentially leading to the pet straying away.
Innovation Solution
A leash design featuring a main strap, a pet attachment arm with an animal connection mechanism, and a pet accessory arm with an accessory connection mechanism, allowing for the attachment of pet accessories and enabling the user to control the pet more effectively by distributing tension across both arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional single-strap leash is used, then the structure is simple, but the pet can pull excessively causing injury or escape
Solution Approach 1:
The leash is divided into two separate arms: a first arm for attaching to the pet and a second arm for attaching to accessories. This segmentation allows the control function to be distributed across multiple components, improving reliability by preventing excessive pulling while maintaining a relatively simple overall structure.
2Reliability
If the leash allows pet movement freedom, then the pet can walk naturally, but the pet may stray away or escape
Solution Approach 1:
A accessory attachment mechanism serves as an intermediary between the pet and the owner's control. This intermediary allows the pet to move naturally while still maintaining effective restraint through the distributed tension system, resolving the contradiction between mobility and control.
3Reliability
If the leash is designed with multiple arms for better control, then pet pulling is reduced, but the device complexity increases
Solution Approach 1:
The second arm of the leash serves multiple functions: it can attach to various accessories (waste bag dispensers, toys, treats) and also contributes to the control mechanism. This multi-functionality reduces the need for separate components, achieving better pulling control while minimizing the increase in device complexity.

AI summary
A method of using a leash includes holding the leash, the leash including a main strap, a pet attachment arm connected to the main strap, the pet attachment arm including an animal connection mechanism, and a pet accessory arm connected to the main strap, the pet accessory arm including an accessory connection mechanism; and connecting the pet attachment arm to a pet.
