Pet Restraint Multi-Spool Retraction Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet restraining systems are inconvenient and potentially hazardous due to their dual-element design, which requires carrying a separate leash and can lead to loss and increased tension forces causing pet strangulation when the tether is retracted.
Innovation Solution
A single-unit restraining system with a multi-spool retraction mechanism integrated into the attachment element, allowing the tether to be safely extended and retracted without wrapping around the pet's neck, and featuring a locking mechanism and sensor for tension detection to ensure pet safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional leash and collar combination is used, then the tether element can be extended for pet control, but the leash must be carried separately which is burdensome and can lead to loss or misplacement
Solution Approach 1:
The patent combines the attachment element (collar) and tether element (leash) into a single integrated restraining system. The tether element is stored within the attachment element, eliminating the need to carry a separate leash while maintaining full control functionality when needed.
Solution Approach 2:
The tether element is nested within the attachment element for storage. When not in use, the leash is contained inside the collar device, allowing the collar to serve dual purposes as both an identification carrier and a retractable leash mechanism.
2Reliability
If the tether element is retracted into the attachment element, then the risk of loss is reduced, but tension forces can cause pet strangulation in conventional systems
Solution Approach 1:
The retraction mechanism is segmented into multiple components including a spool assembly, spring mechanism, and locking system. This segmentation allows controlled deployment and retraction, distributing tension forces safely and preventing sudden strangulation hazards while maintaining secure storage.
3Ease of operation
If a single-unit restraining system is used, then the need to carry separate leash is eliminated, but the attachment element must encase a retraction mechanism increasing device complexity
Solution Approach 1:
The attachment element is designed as a multi-functional device that serves as both a collar for identification and a retractable leash mechanism. This universality consolidates multiple functions into one device, improving ease of operation while the modular design keeps structural complexity manageable.

AI summary
A single-unit restraining system for exercising control over a subject is provided. The restraining system comprises an attachment element adapted to be removably attached around a subject and encasing a retraction mechanism configured to extend and retract a tether element. The retraction mechanism comprises a multi-spool configuration which allows spooling or coiling of the tether element into the attachment element without requiring the tether element to complete 360-degree revolutions around a vertical axis. Tension forces associated with spooling the tether element are reduced and potential harm to the subject is reduced. The restraining system is configured to detach from the subject upon detecting tension forces exceeding a threshold amount.
