Ground Anchor Holder with Pivotal Stabilizers for Soil Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground anchors lack versatility and stability across different soil types, such as sand, dirt, and reinforced ground, and are not easily transportable for various applications.
Innovation Solution
A ground anchor design featuring a rotatably supported holder with pivotal stabilizers that can be swung out and extended, providing secure purchase in the ground by relieving friction-induced torque and allowing for adjustable orientation based on soil firmness, along with an exchangeable ground screw and a pivoting holder that acts as a lever for screwing into the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stabilizers are made rigid and fixed, then stability in the ground is improved, but adaptability to different soil types deteriorates
Solution Approach 1:
The stabilizers are designed with a telescopic mechanism that allows them to extend or retract based on ground conditions. When encountering resistant ground, the stabilizers can be extended to provide additional leverage and stability. This dynamic adjustment capability enables the same device to adapt to various soil types while maintaining reliable anchoring.
2Reliability
If the holder is tightly fixed to the ground screw, then stability is improved, but ease of transport deteriorates
Solution Approach 1:
The holder is rotatably supported in the sleeve, allowing it to be rotated into different positions. For transport, the holder can be rotated to a compact position. During installation, the holder can be rotated to an operational position where it forms a lever for screwing the ground screw into the ground, providing both ease of transport and stability when needed.
3Reliability
If stabilizers are extended telescopically, then stability in soft ground is improved, but device complexity deteriorates
Solution Approach 1:
The stabilizers utilize a telescopic mechanism where sections are nested within each other, similar to a nested doll structure. This allows the stabilizers to extend to greater lengths for soft ground conditions while maintaining a compact form when retracted, providing enhanced stability without permanently increasing device complexity.
4Ease of operation
If the holder acts as a lever for screwing, then ease of installation is improved, but device complexity deteriorates
Solution Approach 1:
The holder serves multiple functions: it provides structural support for the parasol, acts as a lever for screwing the ground screw into the ground during installation, and can be rotated to different positions for transport and operation. This multi-functionality eliminates the need for separate installation tools, improving ease of installation without significantly increasing overall device complexity.
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 design ensures secure anchoring across various soil types, reduces transport complexity, and provides a stable base for objects like parasols and poles, with adjustable stabilizer orientation for optimal friction and torque management.
Implementation Method 1
the stabilizers are pressed against the ground, since the stops limit the swinging-out of the stabilizers to a predefined angle that is less than 90°... This design ensures secure purchase in the ground
Implementation Method 2
the holder can be pivoted by 90° with respect to the ground screw and, in the angled position, forms a lever for screwing the ground screw
Implementation Method 3
The ground screw, which can be freely rotated in the sleeve, can be either screwed into the ground or screwed onto a thread of the ground screw

AI summary
The invention relates to a ground anchor with a mounting (1) for a parasol or the like, having a sleeve (8) which is pushed over the mounting (1) and on which stabilizers (9, 10, 11) are mounted that can be folded out in a radial or preferably tangential manner. A ground screw (4) is connected to the mounting (1) on the ground side and opposite the object be supported, for example the parasol. A driver, such as a projecting section, a shoulder, or a nut (12) which can be screwed onto the mounting for example, drives the sleeve (8) during the screw-in process and expands the stabilizers (9, 10, 11) against the ground. The mounting (1) can be angled relative to the ground screw (4) by 90° and thus forms a lever for rotating the ground screw (4). The stabilizers (9, 10, 11) can be pivoted outwards in a tangential manner selectively clockwise as well as counterclockwise to a limited degree as a result of stops (14, 15).
