One-Handed Pet Leash Securing Device with Spring-Loaded Clasp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet leashes are difficult to secure to fixed objects quickly and easily, often requiring knotting or the use of lock or code devices that can be cumbersome and inconvenient.
Innovation Solution
A leash with a securing device featuring a curved rigid element and a spring-loaded clasp, allowing the leash to be easily wrapped around a fixed object and secured with one-handed operation, using a handle and ergonomic design for comfort and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing leashes are tied around or knotted to a fixed object, then the pet can be secured to the object, but it takes time to knot and unknot and may not work with all types of leashes
Solution Approach 1:
The leash is divided into distinct functional segments: a cord member for attachment, a retention member for securing to the pet, and a specialized securing device with a rigid element and clasp element for quick attachment to fixed objects. This segmentation allows each part to perform its specific function efficiently without requiring complex knotting operations.
Solution Approach 2:
The securing device acts as an intermediary mechanism between the leash cord and the fixed object. Instead of directly knotting the cord to the object, the clasp element engages with the rigid element to provide a quick-connect interface, eliminating the need for traditional knotting while maintaining secure attachment.
2Reliability
If leashes have a lock or code device integrated on them, then the leash can be locked into place to prevent theft, but it requires either having a key on a person or remembering a code
Solution Approach 1:
The securing device is designed to be self-contained and self-operating. The clasp element can be manually engaged and disengaged by the user without requiring external keys, codes, or additional devices. The ergonomic feature provides mechanical advantage to facilitate easy operation by hand, making the system both secure and user-friendly.
3Strength
If leashes require two-handed operation to secure, then the securing mechanism can be more robust, but it reduces convenience for the user
Solution Approach 1:
The rigid element is formed as a curved structure that provides both structural strength and ergonomic contours. The curvature allows the element to resist forces while also conforming to the user's hand shape, enabling effective one-handed operation. The curved geometry distributes forces efficiently throughout the structure, maintaining securing strength despite the simplified one-handed interface.
Solution Approach 2:
The clasp element is designed to move dynamically between engaged and disengaged states. During engagement, the clasp element flexes and snaps into place against the rigid element, providing secure attachment. During release, the ergonomic feature allows the user to easily deflect the clasp element out of its engaged position. This dynamic design enables strong securing with simple one-handed operation.

AI summary
A leash with an integrated leash securing device having a cord member, with a retention member on a distal end and a handle formed on a proximal end. The leash securing device is integrated on the leash with the cord member passing through the leash securing device and the handle is formed by forming a loop with the proximal end of the cord member returning into the leash securing device. An end of the handle within the leash securing device is secured via a fastener inserted through the leash securing device pushing the handle portion within the leash securing device against a surface of the leash securing device. The leash securing device includes a clasping element and an ergonomic feature that allow a one-handed use to secure a pet, that is on the leash, to a fixed object allowing an owner to be hands free.
