Retractable Dog Leash Attachment for Quick Object Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog leashes require a multi-step process to attach to various sized objects, which is cumbersome and inefficient.
Innovation Solution
A dog leash attachment system featuring a retractable tether mechanism with a securing mechanism and connectors that allows for quick and secure attachment to objects without unhooking from the dog collar, including a retractable strap and locking mechanism for easy deployment and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a closed loop leash is used, then the leash can be easily held by the owner, but it cannot be easily attached to objects like light posts without unclasping from the collar
Solution Approach 1:
The leash system is divided into separate functional components: a closed loop handle for holding, a detachable connector for attachment, and a tether for connection. This segmentation allows the handle to remain simple and easy to hold while the connector provides versatile attachment capabilities to various objects without requiring unclasping from the collar.
2Reliability
If a clasp and closed loop leash is used, then the leash can be securely attached to the collar, but the attachment to objects requires multiple steps including unclasping, wrapping, and re-hooking
Solution Approach 1:
The attachment function is extracted from the collar connection and placed in a separate detachable connector. This allows the collar attachment to remain secure and simple while the connector provides quick attachment and detachment capabilities for objects, eliminating the need to unclamp and reattach to the collar.
Solution Approach 2:
The connector is pre-configured with a carabiner or snap mechanism that is ready for quick attachment. The closed loop structure is pre-formed to facilitate easy wrapping around objects, and the connector can be quickly engaged with a single motion, eliminating the multiple sequential steps of unclasping, wrapping, and re-hooking.
3Device complexity
If a traditional leash is used, then the structure is simple, but the process of attaching to various sized objects is difficult and multi-step
Solution Approach 1:
The connector is designed with a carabiner or snap mechanism that can universally attach to various objects of different sizes and shapes. The closed loop structure can be wrapped around objects of varying dimensions, and the adjustable tether length allows adaptation to different object sizes, providing multi-functionality while maintaining overall structural simplicity.

AI summary
A leash attachment includes a housing, a first tether, a securing mechanism, a second tether, a first connector, and a second connector. The first tether includes a first end coupled to the housing. The securing mechanism is configured to removably couple a second end of the first tether to the housing. The second tether includes a first end retractably coupled to the housing. The first connector is coupled to a second end of the second tether. The second connector is coupled to the housing and configured to removably couple to the first connector.
