Solution Overview

Problem

Conventional decoupling mats for floor coverings require thick tile adhesive layers for load transfer, contradicting the desire for slim designs and are unsuitable for moisture-sensitive floor coverings like parquet, the adhesive layer can be eliminated entirely, and the adhesive layer can be used to describe the properties of the mat or panel.

Innovation Solution

A mat or panel with a water- and water-vapor-impermeable flexible plastic layer featuring protruding studs and water vapor drainage channels, allowing for thin or adhesive-free load transfer and moisture drainage, suitable for both tile and parquet installations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional decoupling mats with depressions are used, then load transfer is achieved through stilt-like supports formed by thick adhesive, but the adhesive layer becomes several millimeters thick, increasing floor construction height

Engineering Contradiction:
Improveload transfer capabilityVSAvoidfloor construction height
Core Design Contradiction:
StrengthVSLength of stationary object

Solution Approach 1:

The patent inverts the conventional depression structure into a protrusion structure. Instead of having depressions on the upper surface with channels on the underside (conventional mats), the invention has protrusions on the upper surface with channels on the upper side. This inversion eliminates the need for thick adhesive layers while maintaining load transfer capability through the protrusions themselves.

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

Solution Approach 2:

The patent extracts the load-bearing function from the adhesive layer and transfers it to the protrusions of the plastic layer. By taking out the need for thick adhesive, the invention reduces floor construction height while maintaining structural integrity and load transfer capability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If decoupling mats are used for moisture-resistant floor coverings, then rising damp is channeled away through channels, but the screed layer requires long drying time before installation can proceed

Engineering Contradiction:
Improverising damp protectionVSAvoiddrying time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent introduces the plastic layer with drainage channels as an intermediary between the screed layer and the floor covering. This intermediary layer actively manages moisture through channels on its upper side, preventing rising damp from reaching the floor covering while allowing installation to proceed without long drying waits.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If conventional decoupling mats are used, then tiles can be installed with load distribution, but the same structure is unsuitable for moisture-sensitive floor coverings like parquet due to adhesive incompatibility and moisture accumulation between adjacent mats

Engineering Contradiction:
Improvefloor covering compatibilityVSAvoidmoisture protection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent creates a universal solution that works for both tiles and moisture-sensitive floor coverings like parquet. The plastic layer with protrusions and drainage channels provides a moisture-managing interface compatible with various floor covering types, eliminating the need for different systems for different applications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies different properties to different locations: the upper side has protrusions for load bearing and moisture management, while the lower side has channels for drainage. This local differentiation of properties allows the same structure to serve multiple functions for different floor covering types.

Inventive Principle:
Principle #3Local quality
