Threaded Mobile Foundation Leveling for Uneven Subsoil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile foundations do not allow for leveling of uneven and/or sloping subsoil, requiring time-consuming pre-installation leveling and limiting their application after installation.
Innovation Solution
A height adjustment device for mobile foundations, comprising a rod with a threaded section and a tube with a lateral wall recess, allowing the rod to be rotated relative to the tube, enabling adjustment of the mobile foundation's height and compensation for sloping surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional mobile foundations are used on uneven and/or sloping subsoil, then the foundation can be installed quickly without pre-leveling, but the support surface cannot be leveled and the application is limited
Solution Approach 1:
The support surface is made adjustable through a height adjustment device comprising a rod with threaded portion, a threaded plate, and a tube with cavity. The rod can be rotated within the tube to adjust the height of the support surface, transforming the static foundation into a dynamic system that adapts to uneven and sloping subsoil conditions.
Solution Approach 2:
The height of the support surface is changed by rotating the rod relative to the tube, which moves the threaded plate along the threaded portion of the rod. This changes the vertical position parameter of the support surface, enabling leveling compensation for subsoil unevenness and slopes.
2Manufacturing precision
If the subsoil is leveled before mobile foundation installation, then the support surface can be level, but the process is time-consuming and entails additional costs
Solution Approach 1:
The height adjustment device is pre-installed on the mobile foundation during manufacturing, including the rod with threaded portion, threaded plate, and tube with cavity. This preliminary preparation allows for quick post-installation leveling by simply rotating the rod, eliminating the need for time-consuming pre-installation subsoil leveling.
Solution Approach 2:
The foundation system performs its own leveling function through the integrated height adjustment device, eliminating the need for external leveling operations. The threaded mechanism allows the support surface to be leveled by simple rotation of the rod, making the system self-sufficient for leveling adjustments.
3Ease of manufacture
If conventional mobile foundations are used, then the structure is simple and cost-effective, but subsequent leveling after installation is not possible
Solution Approach 1:
The rod with threaded portion is inserted into the tube with cavity, creating a nested structure. The threaded plate is adjustably held on the threaded portion, and the support surface is connected to the rod. This nested arrangement maintains structural simplicity while enabling post-installation height adjustment through rotation of the rod within the tube.
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
Enables easy post-installation leveling and slope compensation, allowing the mobile foundation to be set up on uneven surfaces with vertical alignment of the support surface, facilitating simple height adjustments and equal load distribution.
Implementation Method 1
a rod with a threaded section, a threaded plate adjustably held on the threaded section
Implementation Method 2
the rod projects laterally into the cavity such that a longitudinal axis of the rod is not parallel to a longitudinal axis of the tube, and wherein the height adjustment device is designed such that the rod is at least partially rotatable relative to the tube about an axis parallel to the longitudinal axis of the tube
Implementation Method 3
the tube comprises at least one wall recess in a lateral surface on an outer side, whereby the rod projects laterally into the cavity
