Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bearing apparatuses fail to independently adjust the height and angular position of a mounting element for a steel construction relative to a base element, limiting their ability to align rails or other construction elements precisely.
Innovation Solution
A bearing apparatus with an adjustable compensation device featuring a mechanical series connection of an articulated joint arrangement and a supporting column, allowing the mounting element to pivot and adjust its height and angular position relative to the base element, using a pivot point on the main axis and varying the supporting column's length through screwing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing bearing apparatuses are used, then the structure is simple, but the ability to independently adjust height and angular position is limited
Solution Approach 1:
The compensation device is segmented into two independent functional components: an articulated joint arrangement for angular position adjustment and a supporting column with variable length for height adjustment. This segmentation allows each component to perform its specific function independently, achieving comprehensive adjustability while maintaining manageable complexity through modular design.
Solution Approach 2:
The bearing apparatus incorporates dynamic adjustment capabilities through the articulated joint arrangement that enables pivoting motion for angular adjustment, and the variable length supporting column that allows height adjustment. These dynamic features transform a static bearing structure into an adaptable system that can compensate for deviations in rail course and alignment.
2Manufacturing precision
If the mounting element is fixed relative to the base element, then the structure is stable, but the alignment precision of rails is insufficient
Solution Approach 1:
The compensation device provides dynamic adjustment capabilities during installation and commissioning, allowing the mounting element to be positioned precisely relative to the base element. The articulated joint arrangement enables angular adjustment for precise alignment, while the variable length supporting column allows height adjustment, ensuring both ease of operation during setup and high alignment precision.
Solution Approach 2:
The compensation device allows changing key geometric parameters (height and angular position) of the mounting element relative to the base element. By adjusting these parameters, the system achieves precise alignment of rails while maintaining the ability to adapt to different installation conditions and supporting structure deviations.
3Adaptability or versatility
If the supporting column has fixed length, then the structure is simple, but the height adjustment capability is lost
Solution Approach 1:
The supporting column is designed as a segmented, variable length mechanism composed of multiple sections that can be extended or retracted. This segmentation allows height adjustment while maintaining structural simplicity through modular construction, where each section can be independently positioned to achieve the desired height.
Solution Approach 2:
The variable length supporting column acts as an intermediary element between the base element and the mounting element, providing height adjustment capability. This intermediary mechanism absorbs the complexity of height variation, allowing the main bearing structure to remain relatively simple while achieving the required adaptability in vertical positioning.

Implementation Method 1
a supporting column (27) comprising an inner column (31) and an outer column (39) and a length along the virtual main axis (36) which can be varied by screwing the inner column (31) in the outer column (39)
Implementation Method 2
The unlocked articulated joint arrangement (26) allows the mounting element (4) to pivot relative to the base element (5) about any pivot axis which intersects the main axis (36) at a right angle at the pivot point (35)

AI summary
A bearing apparatus has a mounting element for mounting a construction element of a steel construction, a base element to be fastened to a supporting structure and an adjustable compensation device for adjusting a height position and an angular position of the mounting element relative to the base element and supporting the mounting element at the base element in direction of a virtual main axis. The compensation device comprises a mechanical series connection of a lockable articulated joint arrangement and a supporting column. The unlocked articulated joint arrangement allows the mounting element to be pivoted relative to the base element about any pivot axis orthogonally intersecting the main axis. The supporting column has a length which is variable by screwing an inner column in an outer column of the supporting column. A screwed-in position of the supporting column is fixed by the construction element mounted to the mounting element.
