Dog Training Leash With Repositionable Neck-Placement Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slip lead leashes often slip downwards during training, causing physical harm and allowing dogs to escape, despite proper placement being crucial for safety.
Innovation Solution
The leash features a ring with a repositionable stop and differential material regions to control grip and movement, ensuring proper neck positioning and providing feedback to the trainer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a typical slip lead leash is used without additional features, then the basic training function is provided, but the leash slips downwards into a dangerous position when the dog lunges forward
Solution Approach 1:
The patent applies preliminary action by providing visual indicators (contrasting color regions) before the leash slips, allowing the handler to see the actual placement versus the intended placement. This early visual feedback enables the handler to correct positioning before the dangerous slippage occurs, preventing physical harm to the dog.
Solution Approach 2:
The patent implements feedback through contrasting color regions that provide continuous visual information about leash placement. The different colors show the handler whether the leash is in the correct position or has slipped, enabling real-time correction to maintain safe and effective training conditions.
2Ease of operation
If the slip lead leash is placed high on the neck for proper training, then effective behavior correction is achieved, but the leash is hard to keep in proper placement
Solution Approach 1:
The contrasting color regions provide immediate visual feedback to the handler about whether the leash is correctly positioned high on the neck or has slipped downward. This feedback mechanism makes it easier to maintain proper placement without requiring constant manual adjustment or guesswork.
Solution Approach 2:
The patent uses color changes (contrasting color regions) to indicate different leash placement states. This visual differentiation makes it easy for the handler to identify correct versus incorrect positioning, significantly improving the ease of operation and placement accuracy.
3Reliability
If the collar loop opening is expanded when the leash slips down, then the dog can escape, but the basic slip lead structure allows this slippage
Solution Approach 1:
The visual indicators provide early warning before the collar loop opens sufficiently for escape. The handler sees the leash has slipped (via color indication) and can react to reclose the loop before the dog can escape, maintaining containment reliability without adding mechanical complexity.

AI summary
A dog training leash having a ring formed with a ring aperture, a flexible body having a first end attached to the ring and a second end, wherein the second end passes through the ring aperture, and a stop is repositionably engaged with the flexible body between the ring and the second end. The flexible body includes a leash material property differential region, a leash contrast region, or a leash grip enhancement region, which improve the performance of the leash.
