Ground Anchor Expansion and Plate Adjustment Without Surface Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems fail to anchor by first fixing a deformable element in a cavity and later adjusting the outer part of the anchor to the ground surface.
Innovation Solution
A method and device involving a rod with a deformable element that is deformed by traction, anchored to the ground, and adjusted by braking the rod's stroke to break a bolt, allowing the plate to descend and secure against the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the rod continues its upward movement after deforming the deformable element, then the anchoring force is maximized, but the plate cannot be adjusted to the ground surface eliminating clearances
Solution Approach 1:
The device is divided into two functional segments: a lower anchoring segment with the deformable element that expands to provide anchoring force, and an upper adjustment segment with the plate that can be independently positioned. The bolt connects these segments, allowing the upper segment to be adjusted downward after anchoring to eliminate clearances between the plate and ground surface.
Solution Approach 2:
The system transitions from a static connected state (when the bolt maintains relative position between conduits) to a dynamic adjusted state (when the bolt breaks and the plate descends). This allows the plate to be dynamically repositioned after anchoring to achieve precise contact with the ground surface, resolving the contradiction between maximizing anchoring force and achieving precise adjustment.
2Device complexity
If the bolt maintains the relative position between main and secondary conduits, then the device structure is simple and compact, but the plate cannot be adjusted to eliminate clearances with the ground surface
Solution Approach 1:
The bolt is designed to maintain the relative position between conduits during installation and anchoring operations, providing a simple and compact structure. After the deformable element is deployed and anchoring is achieved, the bolt is intentionally broken as a preliminary action to enable subsequent plate adjustment. This preliminary breaking of the bolt allows the plate to descend and contact the ground surface, achieving precise adjustment without complicating the overall device structure.
3Manufacturing precision
If the rod is braked to cause the bolt to break, then the plate can be adjusted to the ground surface, but the device requires an additional braking mechanism
Solution Approach 1:
The bolt serves as an intermediary element that connects the rod to the plate and maintains relative position during operation. Instead of adding a separate braking mechanism, the system uses the bolt itself as the braking element - when the rod is braked during upward movement, the tension caused by continued rod tension (or mechanical interference from the brake) causes the bolt to break. This intermediary approach achieves plate adjustment without requiring an additional dedicated braking mechanism, minimizing 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 device effectively anchors elements to the ground by ensuring the deformable element remains expanded and the plate is securely adjusted to the ground surface, enhancing stability and fixation.
Implementation Method 1
a deformable element arranged at the lower end of the secondary conduit... the rod, in its upward movement and being attached to at least one actuator, causes the deformation of the deformable part that thus anchors the device to the ground
Implementation Method 2
the pressure and friction generated by that deformed element causes the device to be anchored to the ground
Implementation Method 3
by braking the ascent of the rod, the tension applied on it causes the bolt to break
Implementation Method 4
the descent of the plate and the main conduit, thus adjusting the plate to the ground

AI summary
The method comprises a first step of inserting the device into a cavity, a second step wherein a tractive device pulls on a rod and this, in its upward movement, actuates an actuator and causes the deformation of a deformable element that when deformed occupies the section of the cavity and is anchored to the ground, a third step wherein the stroke of the rod is braked by the action of a stop, a fourth step of tensioning the rod and downward pressure on the plate, a fifth step of breaking a bolt and lowering the plate which tightens against the ground and a sixth step wherein the rod is secured in position.
