Remote Release Leash Toggle for Slack-Independent Unclipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pet leashes require manual unclipping, which can be difficult for individuals with physical limitations and is inefficient, especially when the leash is slack or when quick release is needed.
Innovation Solution
A remote release leash with a toggle mechanism that allows the user to release the clip from a distance, independent of leash tension, using a toggle to move the connector between closed and open states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual unclipping mechanism is used, then the leash can be securely attached to the pet's collar, but it becomes difficult and time-consuming to release when the pet is excited, muddy, or pulling
Solution Approach 1:
The release mechanism is divided into separate functional components: a toggle component with movable and fixed arms, a connector component with retaining arms, and a leash body. This segmentation allows the release function to be isolated and operated independently from the attachment function, enabling easy remote release without affecting the secure attachment capability.
Solution Approach 2:
The toggle component acts as an intermediary mechanism between the user's hand and the connector. By manipulating the toggle, the user can remotely actuate the release of the connector without directly touching the pet or collar, solving the problem of difficult manual unclipping in challenging situations.
2Productivity
If existing quick-release leashes are used, then release speed is improved, but they fail to function when the leash is slack
Solution Approach 1:
The connector component incorporates resilient (spring) arms that can dynamically adapt to different leash tension conditions. The resilient nature of the arms allows them to engage and disengage the D-ring effectively whether the leash is under tension or completely slack, providing consistent quick-release functionality in all conditions.
Solution Approach 2:
The resilient arms change their physical state and positioning based on leash tension parameters. When tension is applied, the arms maintain engagement; when tension is released or the leash goes slack, the arms can still respond to toggle actuation for release. This parameter adaptability ensures the mechanism works across the full range of operational conditions.
3Ease of operation
If manual unclipping is required, then the structure can be simple, but individuals with physical limitations find it difficult to reach and unclip the leash
Solution Approach 1:
The toggle component serves as a remote intermediary control mechanism positioned within easy reach of the user. By actuating the toggle, the user can remotely trigger the release of the connector without needing to physically reach down to the pet's collar level, making the system accessible to individuals with mobility or back limitations.
Solution Approach 2:
The release control is moved from the vertical dimension (requiring bending down to reach the collar) to a horizontal dimension where the toggle can be operated from a comfortable standing position. This dimensional shift in control accessibility solves the problem for users with physical limitations.

AI summary
A remote release leash includes a leash body having a proximal end and a distal end opposite to the proximal end, a connector disposed at the distal end of the leash body, and a release assembly extending along the leash body and mechanically connected to the connector. The release assembly has a toggle. The toggle is actuatable to move the connector from a closed state in which the connector retains a clipped element to an open state in which the clipped element is released from the connector.
