Resilient Dog Leash with Segmented Rings for Hands-Free and Vehicle Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog leashes lack versatility and cannot perform multiple functions such as standard leading, hands-free use, double leading, vehicle restraint, and tethering, with none providing the unique combination of fixed and movable rings for varied applications.
Innovation Solution
A dog leash designed with separable halves, featuring snaps, fixed and movable circular rings, and removable clamps, allowing for adjustable configurations for leading one or two dogs, securing in vehicles, and hands-free use, made from resilient material like durable rubber to minimize stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dog leash is made from resilient material, then stress on users and dogs is minimized, but the leash lacks structural rigidity needed for secure restraint
Solution Approach 1:
The leash is divided into two separate halves that can be used independently or combined. Each half contains fixed and movable rings that can be configured in different ways, allowing the resilient material to provide stress reduction while the ring structure provides structural rigidity for secure restraint when needed.
Solution Approach 2:
The leash incorporates movable rings that can slide along the leash halves, allowing the structure to dynamically adjust between flexible configurations for comfort and rigid configurations for secure restraint. The rings can be positioned to create fixed loops or allow movement depending on the restraint needs.
2Adaptability or versatility
If a dog leash is designed with fixed and movable rings for multiple functions, then versatility is improved, but device complexity increases
Solution Approach 1:
The leash is designed as a universal restraint system where two leash halves with fixed and movable rings can be configured for multiple functions including leading one or two dogs, hands-free operation, vehicle restraint, and tethering. The same basic components serve multiple purposes through different configurations.
Solution Approach 2:
Two separate leash halves are designed to work together as a coordinated system. The halves can be used independently for simple tasks or combined with their rings and clips for more complex multifunctional applications, allowing the system to merge components for enhanced versatility when needed.
3Ease of operation
If a dog leash is made separable into halves with clips, then ease of adjustment and storage is improved, but reliability of connection may be reduced
Solution Approach 1:
The leash is segmented into two halves connected by reliable clips rather than a single continuous piece. This segmentation allows for easy adjustment, storage, and independent use of each half while the clips provide secure connections when the halves need to be joined for multifunctional applications.

AI summary
A dog leash that is capable of serving a multitude of purposes. The dog leash is made of resilient material, allowing it to stretch, which decreases the stress on both the user and the dog. The leash can be configured to lead one dog or two dogs at the same time. The leash can be used as a hands free lead, worn around the user's waist or shoulder. When worn around the waist, it allows 360 degrees of movement by the dog. The lead is also capable of being used as a seat restraint in a motor vehicle or as a tether. The leash is readily adjustable, suited for all size dogs, and can be especially useful for service dogs.
