Solution Overview

Problem

Existing fixing devices for mounting wall elements are cumbersome and difficult to use, especially with heavy or thick elements, often requiring manual holding and complex connections to secure the closing profiles.

Innovation Solution

A fixing device with a rotatable securing element that engages with a support profile through a 90° rotation, allowing easy attachment and secure locking, and a closing profile with a click connection to prevent detachment, facilitating quick and flexible erection of walls with heavy elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional drilling and anchoring methods are used to mount wall elements, then secure fixation is achieved, but the structural material is damaged and the process is time-consuming

Engineering Contradiction:
Improvefixation securityVSAvoidmounting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fixing device is pre-assembled with the angle bracket and fastening components before installation. The L-shaped profile is inserted into the channel element in advance, and the angle bracket is positioned on the opposite side, so that during mounting only the final fastening action is needed, eliminating the need for on-site drilling and preparation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mounting system is divided into separate modular components: the L-shaped profile inserted into the channel, the angle bracket positioned on the opposite side, and the fastening mechanism. This segmentation allows each component to be prepared independently and assembled quickly without damaging the structural material.

Inventive Principle:
Principle #1Segmentation

2Reliability

If traditional drilling and anchoring methods are used to mount wall elements, then secure fixation is achieved, but the structural material is damaged

Engineering Contradiction:
Improvefixation securityVSAvoidstructural material damage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The harmful drilling action is completely removed from the mounting process. Instead of drilling into the structural concrete element, the system uses a channel element with an L-shaped profile that inserts without damage, and fastens through the angle bracket on the opposite side, eliminating structural material damage entirely.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The angle bracket acts as an intermediary element that transfers the fastening force from one side of the channel element to the other without requiring direct attachment to the structural concrete element. This mediator approach allows secure fixation while protecting the structural material from damage.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If wall elements are mounted using conventional methods, then fixation is achieved, but the process requires multiple steps and is complex

Engineering Contradiction:
Improvefixation securityVSAvoidmounting process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple functions are merged into a single integrated system: the L-shaped profile provides both structural support and positioning within the channel element, the angle bracket provides both alignment and fastening attachment points, and the entire assembly works together as a unified mounting solution that simplifies the process to essential steps only.

Inventive Principle:
Principle #5Merging (Combining)

4Manufacturing precision

If precise alignment is required for wall elements, then mounting accuracy is improved, but the positioning process becomes more difficult

Engineering Contradiction:
Improvemounting accuracyVSAvoidpositioning ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The L-shaped profile creates a standardized interface within the channel element that provides consistent positioning geometry. This standardized interface ensures that wall elements are automatically aligned to the same reference level, making positioning easier while maintaining precise mounting accuracy across all installations.

Inventive Principle:
Principle #12Equipotentiality

AI summary

The invention concerns a fixing device (2) for mounting wall elements (3, 28) for constructing a wall, comprising: a support profile (4, 25); a securing element (5) which is designed to extend between the wall elements (3, 28) and can be twisted relative to the support profile (4, 25) between a first position in which an engagement element (9) of the securing element (5) remains separate from the support profile (4, 25), and a second position in which the engagement element (9) engages on the support profile (4, 25) for fixing and secures the wall elements (3, 27); and a closing profile (6) which in the second position is attachable to the securing element (5) and comprises a blocking element (10) for preventing the securing element (5) from twisting back.
