Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leashes for multiple pets or hands-free use require multiple pieces and lack efficient adjustability and versatility in attachment methods.
Innovation Solution
A multipurpose leash with swivelable snap connectors on each end, an adjustable ring along the strap, and stationary rings for secure attachment and adjustable length, allowing for use with two pets and hands-free operation by wrapping around the user's waist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate harnesses and belts are used for hands-free use, then hands-free functionality is achieved, but device complexity increases and multiple pieces are required
Solution Approach 1:
The patent combines the leash function and hands-free harness function into a single integrated device. The strap includes both attachment ends for connecting to pets and a waist engagement mechanism, eliminating the need for separate harnesses and belts while providing both leash control and hands-free operation capability
Solution Approach 2:
The single strap device serves multiple functions: it acts as a traditional leash when attached to one pet, provides hands-free operation when wrapped around the user's waist, and can accommodate multiple pets simultaneously. This multi-functionality replaces the need for multiple specialized devices
2Adaptability or versatility
If traditional leashes are used for multiple pets, then attachment capability is provided, but adjustability and versatility in attachment methods are limited
Solution Approach 1:
The patent incorporates movable rings that can slide along the strap at different positions, allowing dynamic adjustment of attachment points. These rings can be positioned anywhere along the strap length and secured, providing versatile attachment options for multiple pets at different locations without requiring complex adjustable mechanisms
Solution Approach 2:
The strap is divided into functional segments with attachment points distributed along its length. Each end and intermediate positions can independently attach to different pets or serve different functions, allowing the single device to handle multiple pets simultaneously with independent control over each attachment point

AI summary
A multipurpose leash including an elongated strap, a fastener on each end of the strap, an adjustable ring that is movable along the strap, and at least one stationary ring attached to the strap, such as a first stationary ring affixed at an end of the strap and a second stationary ring attached along the length of the strap. The adjustable ring preferably slides along the strap with an oval, circular or D-shaped ring transverse to the strap. The multiple uses and functions include use with two pets, hands-free use with one end of the strap capable of being wrapped around the waist of the human user, and an adjustable length with fasteners connected to various rings.
