Rotatable Pet Lead Holder for Tangling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet securing devices are not compatible with standard pet leads, particularly retractable leads, and often result in tangling or require specialized cables, making them inconvenient for use in various settings.
Innovation Solution
A universal pet securing device featuring a rotatable holder that accommodates retractable pet leads, with a strap mechanism for secure attachment and adjustable length, allowing the pet to roam without tangling, and a post for easy insertion and removal from the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cork-screw style stake with cable is used, then the pet can be secured to the ground, but the cable easily tangles and it is time consuming to attach
Solution Approach 1:
The device is divided into distinct functional components: a ground stake, a holder assembly, and a retractable lead receiver. This segmentation allows each component to perform its specific function efficiently, with the holder providing quick attachment/detachment capability separate from the ground anchoring function.
Solution Approach 2:
The retractable lead mechanism provides self-service by automatically retracting the tape when the pet moves away, eliminating the need for manual cable management and preventing tangling without user intervention. The spring-loaded mechanism automatically winds the tape back into the housing.
2Reliability
If a conventional cork-screw style stake with cable is used, then the pet can be secured to the ground, but the cable easily tangles
Solution Approach 1:
The holder assembly is designed to rotate freely relative to the ground stake, allowing dynamic adjustment to accommodate the pet's movement in any direction. This rotational freedom prevents the lead from winding around the stake and creating tangles, as the holder can pivot to maintain proper lead alignment.
Solution Approach 2:
The retractable lead mechanism automatically manages the tape tension and retraction, preventing tangling through self-regulating mechanical action. The spring mechanism ensures the tape remains taut when extended and automatically winds back when released, eliminating the need for manual intervention to prevent tangles.
3Reliability
If a specialised cable is used with the securing device, then the device can function, but it is not compatible with standard pet leads
Solution Approach 1:
The holder assembly is designed with a universal interface that accepts standard retractable pet leads. The opening in the holder accommodates various lead sizes and types, allowing the device to work with conventional pet leads rather than requiring specialized cables. This multi-functionality enables compatibility across different lead specifications.
4Device complexity
If the holder is fixed relative to the post, then the structure is simple, but the pet lead winds or tangles around the post
Solution Approach 1:
The holder assembly incorporates a rotational joint that allows it to pivot freely around the ground stake. This dynamic capability enables the holder to follow the pet's movement and prevent the lead from winding around the stake, while adding minimal structural complexity through a simple rotating connection.
Solution Approach 2:
The holder design features an asymmetric configuration where the lead exit point is positioned to optimize the angle of the lead relative to the stake. This asymmetric arrangement helps guide the lead away from the stake surface, reducing the likelihood of winding and tangling while maintaining structural simplicity.
