Solution Overview

Problem

Existing ceramic tile installations are labor-intensive, costly, and require professional expertise, while floating floor systems lack impact strength and sound insulation, and are prone to water penetration and limited configuration options.

Innovation Solution

A floor system with a ceramic tile top layer and a support layer featuring coupling elements, using a coupling insert for easy installation, and reinforced with resin material for impact resistance, and optionally glued to an underlayment for stability, allowing for sound attenuation and expansion gap bridging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If ceramic tiles are installed using traditional adhesive bonding to a rigid surface, then impact strength and sound insulation are improved, but installation labor intensity and cost increase significantly

Engineering Contradiction:
Improveimpact strengthVSAvoidinstallation labor intensity
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The floor covering system is divided into separate modular components: a modular support layer with integrated coupling elements and a decorative top layer. This segmentation allows the support layer to provide structural bonding while the top layer provides aesthetics, reducing the need for complex adhesive applications and professional installation skills.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support layer combines multiple functions into a single component: mechanical coupling between tiles, bonding to the subfloor, sound insulation, and structural support. This merging eliminates the need for separate adhesive compounds and simplifies installation to a snap-fit process.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If ceramic tiles are installed using traditional adhesive bonding, then impact strength and sound insulation are improved, but installation time and cost increase

Engineering Contradiction:
Improveimpact strengthVSAvoidinstallation speed
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

By separating the bonding function into the support layer's integrated coupling elements, the installation process becomes a simple snap-fit operation rather than requiring time-consuming adhesive application, leveling, and grouting processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support layer's coupling elements are designed to automatically align and secure adjacent tiles together through their interlocking geometry, eliminating the need for professional installers to manually position and secure each tile individually.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If floating floor systems are used without adhesive bonding, then installation ease and flexibility are improved, but impact strength and sound insulation deteriorate

Engineering Contradiction:
Improveinstallation easeVSAvoidimpact strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The support layer merges the floating floor concept with structural bonding capabilities through its integrated coupling elements that snap-fit to both adjacent tiles and the subfloor, providing both installation flexibility and impact resistance simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support layer is constructed as a composite structure combining rigid coupling elements with sound-insulating materials, creating a multi-functional layer that provides both mechanical bonding and acoustic insulation in a single component.

Inventive Principle:
Principle #40Composite materials

4Adaptability or versatility

If floating floor systems are used without adhesive bonding, then installation flexibility is improved, but water resistance deteriorates

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidwater resistance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The support layer integrates water-resistant properties directly into the floating floor structure through its coupling element design and material composition, maintaining water tightness while preserving installation flexibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support layer uses composite materials that combine the flexibility needed for floating installation with water-resistant properties, creating a material that simultaneously provides both installation adaptability and water protection.

Inventive Principle:
Principle #40Composite materials

5Ease of operation

If coupling elements are integrated into the support layer, then installation simplicity is improved, but device complexity increases

Engineering Contradiction:
Improveinstallation simplicityVSAvoidsupport layer structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The coupling elements are merged with the support layer as an integrated component rather than separate parts, simplifying installation to a snap-fit operation while the modular nature of the support layer keeps the overall system manageable.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support layer serves multiple functions simultaneously: providing structural support, enabling tile coupling, ensuring water resistance, and offering sound insulation, which reduces the need for additional separate components.

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