Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation parts for concrete segments face challenges in aligning and securing electrical components on ferromagnetic formwork walls, particularly when positioning is difficult and removal of magnets after concrete casting is cumbersome.
Innovation Solution
An installation part with a recess designed to accommodate a magnet, featuring complementary contours that secure the magnet in a defined position and orientation, allowing for easy alignment and removal, and includes a fastening element for releasable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnet is temporarily incorporated into the installation component for magnetic fixation to a ferromagnetic formwork wall, then the installation part can be secured to the formwork panel, but the installation box is difficult to align on the formwork wall so that it assumes a predetermined and defined position and orientation
Solution Approach 1:
The installation part is segmented into a magnet-receiving element (recess) and an installation body. The recess is designed with specific geometric contours that receive and align the magnet, separating the fixation function from the installation body while ensuring precise positioning through the interlocking geometry of the recess and magnet
Solution Approach 2:
The recess is designed with an asymmetric contour that complements the magnet's shape. This asymmetric geometry ensures that the magnet can only be inserted in the correct orientation, automatically aligning the installation part with the formwork wall in the predetermined position and orientation without requiring additional alignment operations
2Reliability
If a magnet is used for fixation, then the installation part can be securely attached during concrete pouring, but the quick and cost-effective removal of the magnet from the formwork panel after concrete segment casting is problematic
Solution Approach 1:
The magnet is extracted as a separate, removable component from the installation part. The recess is designed with a opening that allows the magnet to be easily inserted before casting and removed after casting without damaging the installation part or the concrete segment, enabling quick and cost-effective magnet removal
Solution Approach 2:
The magnet is temporarily incorporated into the installation part before the concrete pouring process. After the concrete segment is cast and the formwork is removed, the magnet can be easily taken out from the recess, allowing for reuse of both the magnet and installation part in subsequent casting operations
3Adaptability or versatility
If the installation part is to be located in the concrete segment on a side that is at the top during pouring, then the installation part can be positioned for top-side installation, but fixing is fundamentally problematic since there is no formwork panel to which fixing would be possible
Solution Approach 1:
Instead of fixing the installation part to the formwork panel from the outside, the magnet is fixed to the formwork panel and the installation part is fixed to the magnet from the inside of the formwork. This inverted fixation approach allows the installation part to be securely held even when positioned on the top side where traditional external fixation would be impossible

AI summary
The application relates to an installation component for installation in a concrete segment to be cast, a concrete segment with an installation component (1), and a method for producing a corresponding concrete segment. The installation component (1) serves for the introduction and/or routing of electrical cables and comprises an installation body (2) with a support surface (3). The support surface (3) is designed to rest against the inner side of a formwork panel during the casting of the concrete segment. A recess is surrounded by the support surface (3) and open towards it. The recess has a circumferential recess wall (6) and a recess base (5). The recess (4) is designed to receive a magnet (7) such that a contour of the recess (4) and a corresponding counter-contour of the magnet (7) secure the magnet (7) in the recess (4) in a defined position and prevent it from rotating.Furthermore, the installation part includes a fastening element (10) for the releasable fixing of the magnet (7) in the recess (4).
