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

VSEngineering 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

Engineering Contradiction:
Improvefixation reliabilityVSAvoidalignment precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #4Asymmetry

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

Engineering Contradiction:
Improvefixation strengthVSAvoidmagnet removal ease
Core Design Contradiction:
ReliabilityVSEase of operation

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveinstallation position flexibilityVSAvoidfixation reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

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

Inventive Principle:
Principle #13The other way round (Inversion)

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).
