Cinch Grip Leash Locking Positionable Hand Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog leashes fail to provide a secure, ergonomic handle that can be locked at adjustable positions and easily retracted to shorter lengths against the pull of a large animal, and often lack effective means to prevent handle movement along the leash without user intervention.
Innovation Solution
The Cinch Grip Leash features a grip handle with a stop mechanism comprising pivoting rollers that lock in place when a release button is pressed, preventing longitudinal movement unless released, and includes a wrist strap for enhanced security, allowing handlers to control large dogs using their strength rather than a leash reel spring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a traditional leash reel spring is used to retract the leash, then the leash can be pulled back, but it cannot provide sufficient control force against large strong dogs
Solution Approach 1:
The leash system allows the handler to directly apply their body weight and strength against the dog's pull through the stop mechanism, eliminating the need for a separate spring mechanism. The handler's own strength becomes the retracting force, providing sufficient control force against large strong dogs.
2Adaptability or versatility
If the grip handle is made movable along the leash for adjustment, then it provides flexibility in positioning, but it cannot prevent movement without user action
Solution Approach 1:
The grip handle incorporates a stop mechanism with rollers that can dynamically switch between two states: moving freely along the leash strap when the handler needs to adjust the position, and locking in place when the handler presses the release button to prevent any movement. This dynamic behavior provides both position adjustment flexibility and position stability as needed.
3Speed
If the leash is designed for quick retraction to shorter lengths, then it enables rapid control changes, but it cannot maintain secure locking at the new position
Solution Approach 1:
Before the handler fully retracts the leash to a shorter length, they press the release button to engage the stop mechanism. This preliminary action ensures that once the desired position is reached, the grip handle immediately locks in place, maintaining secure locking at the new position while allowing quick retraction to that position.
4Ease of operation
If the grip handle is designed for easy securement to the handler's hand, then it improves ease of operation, but it cannot prevent accidental movement or dislodging
Solution Approach 1:
The handle securement system is divided into two independent components: the ergonomic grip portion that is easy to attach and remove from the handler's hand, and the wrist strap portion that provides secure retention and prevents accidental movement or dislodging. This segmentation allows each component to optimize its specific function without compromising the other.

AI summary
Provided is an animal leash with leash strap retractable through an ergonomic hand grip which is releasably fixed to said leash at any length position along the leash strap, and is quickly adjusted by simple push button release and manual repositioning. Leash is fixed against being pulled through handle in either direction until user presses release button, at which time leash may be pulled back to quickly restrain the animal, or pulled forward to allow more length freedom. Handle is equipped with wrist strap to better secure it to handler.
