Solution Overview

Problem

Existing elongate profiled section elements for mounting systems in drywall stud frames, particularly those used for plumbing and electrical installations, lack sufficient structural integrity and rigidity due to thin metal construction and limited fastening options, which can lead to instability and vibration issues, especially when supporting heavy components like shower heads.

Innovation Solution

The profiled section element features a stepped sidewall with aligned rows of holes and a mounting plate, allowing for self-tapping screws to engage through multiple layers of material, providing enhanced stability and rigidity by distributing forces across additional layers of material, and accommodating telescopic adjustment for varying stud spacings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If thin metal construction is used for profiled section elements, then ease of installation and adaptability to stud spacings is improved, but structural integrity and rigidity deteriorate

Engineering Contradiction:
Improveadaptability to stud spacingsVSAvoidstructural integrity
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The patent introduces a stepped sidewall configuration that adds dimensional complexity to the profile structure. The stepped portion creates additional engagement surfaces and layers for fastening, transforming a simple thin-walled C-profile into a multi-layered structure that provides enhanced structural integrity while maintaining the thin metal construction for ease of installation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The sidewall is segmented into multiple sections with different heights, creating distinct functional zones. The stepped sidewall divides the single wall into upper and lower portions that can engage with different components, allowing the thin metal profile to provide multiple fastening points and improve overall structural strength without increasing material thickness.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If thin metal construction is used for profiled section elements, then ease of manufacture and installation is improved, but resistance to forces and vibrations deteriorates

Engineering Contradiction:
Improveease of manufactureVSAvoidresistance to forces and vibrations
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The stepped sidewall adds vertical dimensionality to the fastening interface, creating multiple engagement levels. This dimensional enhancement allows the thin metal profile to resist forces and vibrations more effectively by distributing loads across multiple layers and surfaces, while the overall thin construction remains easy to manufacture.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The profiled section element combines the thin metal C-profile with a stepped sidewall structure that creates a composite fastening system. The stepped portion acts as a structural reinforcement that works together with the main profile body, providing enhanced vibration and force resistance while maintaining the lightweight, easy-to-manufacture characteristics of thin metal construction.

Inventive Principle:
Principle #40Composite materials

3Device complexity

If limited fastening options are provided in standard profiles, then device complexity is reduced, but structural integrity and stability deteriorate

Engineering Contradiction:
Improvefastening system complexityVSAvoidmounting system stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The stepped sidewall creates additional vertical layers for fastening, transforming a single-plane fastening interface into a multi-level engagement system. This dimensional enhancement provides multiple rows of holes at different heights, allowing for more stable mounting configurations without significantly increasing device complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The fastening system is segmented into multiple functional zones: the main bottom flange with mounting holes, and the stepped sidewall with additional rows of holes. This segmentation provides multiple fastening options that enhance stability while maintaining relative simplicity in the overall fastening approach.

Inventive Principle:
Principle #1Segmentation

AI summary

An elongate profiled section element (1) for a mounting system comprises a bottom (2), a top side (3) opposite the bottom (2), and sidewalls (4, 5) extending from the bottom (2) to the top side (3). The top side (3) comprises two flanges (6) which extend from the side walls (4, 5) and delimit between them a longitudinal slot (20). The top side (3) has a smaller width than the bottom (2). At least one of the side walls (4, 5) is a stepped sidewall (5) having a stepped shape seen in cross section. The stepped sidewall (5) has two wall sections (8, 9) facing the opposite sidewall (4) and an intermediate wall section (7) substantially parallel to the bottom (2). The intermediate wall section (7) is provided with a row of holes (10) and the bottom (2) is provided with a row of holes (11) aligned therewith, said holes (10, 11) being adapted to cooperate with a self tapping screw.
