Solution Overview

Problem

The creation of a recess in the base region of a drywall construction for fire protection and sound insulation walls weakens the structural integrity and effectiveness of these features, as existing methods for compensating this weakening are complex and inefficient.

Innovation Solution

Introducing a compensating insulant, such as rock wool, into the intermediate space between the paneling of the stud frame over the vertical height of the recess in the base region to restore fire protection and sound insulation without affecting other structural elements or requiring elaborate modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the outer paneling layer is recessed to create a negative base for baseboard installation, then the baseboard can be flush-mounted for improved interior design, but the fire protection and sound insulation properties of the wall construction are substantially weakened

Engineering Contradiction:
Improvebaseboard flush-mounting capabilityVSAvoidfire protection and sound insulation effectiveness
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

A compensating insulant is introduced as an intermediary element into the intermediate space between the paneling layers at the recessed location. This compensating insulant serves as a mediator that restores the fire protection and sound insulation properties that were removed when the outer paneling layer was recessed, while allowing the baseboard to be flush-mounted.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The compensating insulant is specifically placed only in the intermediate space corresponding to the recessed region, providing localized restoration of fire protection and sound insulation properties where they are most needed, rather than requiring complete repaneling of the entire wall construction.

Inventive Principle:
Principle #3Local quality

2Reliability

If replacement boards are integrated into the wall construction by screwing them to the remaining continuous paneling from the inside, then the fire protection and sound insulation can be maintained, but the installation process becomes extremely elaborate and complex

Engineering Contradiction:
Improvefire protection and sound insulation maintenanceVSAvoidinstallation process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of using replacement boards that require complex integration processes, the invention uses a compensating insulant as a simpler intermediary element that can be directly placed into the intermediate space, significantly reducing installation complexity while maintaining fire protection and sound insulation properties.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention extracts the essential function (fire protection and sound insulation) from the complex replacement board system and implements it through a simpler compensating insulant placed in the intermediate space, eliminating the need for elaborate integration procedures.

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If gypsum blocks or aerated concrete blocks are used to fill the recessed region, then overall strength and fire resistance are improved, but sound insulation is not sufficiently maintained and the assembly process becomes unnecessarily laborious

Engineering Contradiction:
Improveoverall wall strength and fire resistanceVSAvoidsound insulation adequacy
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The invention changes the parameter of the filling material from traditional gypsum or aerated concrete blocks to a specifically designed compensating insulant that has optimized properties for simultaneously providing fire resistance, sound insulation, and structural compensation, thereby improving sound insulation while maintaining other properties.

Inventive Principle:
Principle #35Parameter changes

AI summary

The invention pertains to a process for producing a recess ("negative base") in the base region of a wall construction in the drywall technique, preferably a wall construction with fire protection and/or sound insulation, wherein for the wall construction on a stud frame, using board-shaped construction elements, preferably construction elements containing gypsum and/or cement, a paneling is attached on both sides of the stud frame, and wherein at least one side of the stud frame is provided with a double-layer paneling, the outer paneling layer of which is recessed in order to produce the recess in the base region, characterized in that a compensating insulant is introduced into the intermediate space between the panelings of the stud frame at least over the vertical height of the recess in the base region in order to compensate the weakening of the base region resulting from the recessed paneling.
