Leash and Umbrella Holder with Rotating Anchor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to securely anchor pet leashes and umbrellas to ground surfaces while allowing for 360-degree rotation of the leash to prevent tangling.
Innovation Solution
A device featuring a hollow tubular member with a spiral screw piece for ground engagement, a rotatable center piece with a carabiner for securing pet leashes, and a central cylindrical base to accommodate umbrellas of varying diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed anchor device is used to secure pet leashes and umbrellas to ground surfaces, then secure anchoring is achieved, but the leash cannot rotate freely causing tangling
Solution Approach 1:
The device divides the anchoring system into separate functional components: a fixed hollow tubular member anchored to ground, a rotatable center piece for leash attachment, and a separate umbrella receiving section. This segmentation allows the anchoring function to remain fixed while the leash attachment point rotates independently, preventing tangling while maintaining secure ground attachment.
Solution Approach 2:
The center piece is designed to rotate 360 degrees relative to the fixed hollow tubular member, transforming the static anchoring system into a dynamic one. This rotational freedom allows the leash to move and rotate without constraint while the anchor remains firmly planted in the ground, resolving the contradiction between secure anchoring and free rotation.
2Reliability
If a single fixed anchor point is used, then secure anchoring is achieved, but multiple objects (leash and umbrella) cannot be accommodated simultaneously
Solution Approach 1:
The hollow tubular member serves multiple functions: it anchors the device to ground via the spiral screw piece, provides a rotatable center piece for leash attachment, and includes an opening to receive and secure umbrellas. This multi-functional design allows a single anchor device to securely hold both pet leashes and umbrellas simultaneously, achieving versatility without compromising anchoring reliability.
3Reliability
If a standard umbrella holder is used, then umbrellas can be secured, but umbrellas of various diameters cannot be accommodated
Solution Approach 1:
The top cap is designed with selective engagement capability, allowing it to be positioned at different locations along the hollow tubular member. This dynamic positioning enables the opening diameter to be adjusted to match different umbrella pole diameters, securing various sized umbrellas reliably while maintaining adaptability across different umbrella types.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device securely anchors pet leashes and umbrellas to the ground, allows for 360-degree rotation of the leash to prevent tangling, and accommodates umbrellas of different sizes for shade provision.
Implementation Method 1
a spiral screw piece that is supported from the lower end and that extends away from the lower end of the hollow tubular member; the spiral screw piece for engagement with the ground surface
Implementation Method 2
the rotatable center piece adapted for free rotation relative to the hollow tubular member

AI summary
A device for anchoring an object to a ground surface includes a hollow tubular member having respective upper end and lower end; a spiral screw piece that is supported from the lower end and that extends away from the lower end of the hollow tubular member, the spiral screw piece being for engagement with the ground surface, the upper end of the hollow tubular piece having an opening for receiving the object, a rotatable center piece supported about the hollow tubular member and disposed between the respective lower and upper ends of the hollow tubular member, the rotatable center piece adapted for free rotation relative to the hollow tubular member, and an elongated rod that engages with the hollow tubular member to assist in rotating the hollow tubular member and, in turn, the spiral screw piece in order to securely engage with the device with the ground surface.
