Segmented Dog Leash Assembly for Selective Multi-Dog Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dog leashes are inadequate for controlling multiple dogs of varying weights and heights, as they lack flexibility in length and attachment, making it difficult to selectively correct individual dogs without affecting others, and are often limited in their ability to adapt to different dog characteristics and numbers.
Innovation Solution
A dog leash assembly featuring an elongated handle with removably coupled leash adapters and collar coupling members of varying lengths, allowing for selective control and correction of individual dogs, with the ability to interchange and adjust leash lengths and attachments based on dog size and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single handle controls multiple dogs, then handling efficiency is improved, but selective control of individual dogs deteriorates
Solution Approach 1:
The leash assembly is divided into multiple independent leash adapters (first leash adapter, second leash adapter, etc.) that can be separately attached to the handle. Each adapter connects to a specific dog collar, allowing the handler to selectively control individual dogs by manipulating only the relevant adapter while maintaining efficient multi-dog management
Solution Approach 2:
Leash adapters serve as intermediary components between the handle and dog collars. These adapters enable selective control by acting as intermediate connection points that can be independently manipulated, allowing the handler to transmit control signals to specific dogs without affecting others on the same leash assembly
2Device complexity
If leash length is predetermined and permanently coupled, then device simplicity is improved, but adaptability to different dog characteristics deteriorates
Solution Approach 1:
The leash adapters incorporate adjustable length mechanisms that allow the leash length to be dynamically changed according to the specific needs of each dog. The adapters can be extended or reconfigured to accommodate dogs of varying sizes, strengths, and training levels, providing versatility while maintaining relatively simple device architecture
Solution Approach 2:
The leash system allows modification of the leash length parameter through adjustable adapters. The first leash adapter, second leash adapter, and additional adapters can be configured with different lengths to match the characteristics of different dogs, enabling the same handle to effectively control dogs of various sizes and strengths
3Device complexity
If multiple leashes originate from central points, then device complexity is reduced, but selective signaling to individual dogs deteriorates
Solution Approach 1:
Instead of all leashes originating from a single central point, the system segments the attachment points by providing multiple leash adapters distributed along the handle structure. This segmentation allows the handler to apply corrective forces or signals to specific dogs by manipulating individual adapters without transmitting signals to all dogs simultaneously
Solution Approach 2:
The leash adapters are positioned asymmetrically along the handle rather than all converging at the center. This asymmetric arrangement creates independent control zones for each dog, enabling selective signaling and correction while maintaining a relatively simple overall device structure
4Adaptability or versatility
If leash adapters are removably coupled, then adaptability to different numbers of dogs is improved, but device complexity increases
Solution Approach 1:
The leash system is segmented into modular adapters that can be independently attached or detached from the handle. This segmentation enables the handler to configure the number of active leash adapters according to the number of dogs being walked, providing adaptability while keeping the overall device complexity manageable through standardized connection mechanisms
Solution Approach 2:
The leash adapters are designed with universal attachment mechanisms that allow the same adapter design to be used for different numbers of dogs. The removable coupling system provides multi-functionality, enabling the handle to effectively manage one dog, two dogs, or more by simply adding or removing adapters rather than requiring different device configurations

AI summary
A dog leash assembly includes (1) an elongated handle portion, (2) a first leash adapter coupled to the first end of the handle portion and having a first leash connector, and (3) a second leash adapter coupled to the second end of the elongated handle portion and a second leash connector, the second leash connector being removably couplable to the first leash connector. A first collar coupling member has a first end that is removably couplable to the first leash connector and/or the second leash connector a second end with a first collar connector that is removably couplable to a dog collar.
