Solution Overview

Problem

Existing seamless slab installations face challenges with joint areas being weak points for wear, thermal, and mechanical stresses, and anchoring complexities leading to high rejects, especially in commercial applications.

Innovation Solution

The method involves designing edge zones of panels with channel sections that form a continuous duct network, allowing for a joint-free connection using a hardenable filling compound, which is injected and hardens to secure the panels without visible joints, while allowing for conventional fastening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If panels are installed with visible joints using conventional methods, then the installation process is simple, but the joint areas become weak points for wear, thermal stresses, and mechanical damage

Engineering Contradiction:
Improvejoint strengthVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the joint area from the visible surface by creating subsurface channels that extend below the panel edges. The filling compound is placed in these subsurface channels rather than in visible surface joints, effectively removing the weak joint structure from the visible and load-bearing surface while maintaining panel connectivity through the embedded channels.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention transitions the joint structure from a two-dimensional surface feature to a three-dimensional subsurface feature. Channels are created that extend vertically below the panel edges, allowing the filling compound to anchor panels in the depth dimension rather than relying on surface-level joints. This dimensional transition strengthens the connection while keeping the surface seamless.

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

2Strength

If bonding in the edge area is used to connect panels, then the installation is simpler, but the bonding is insufficient to withstand high mechanical and thermal loads

Engineering Contradiction:
Improvepanel connection strengthVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The invention embeds channels within the panel edge zones, creating a nested structure where the filling compound is housed inside subsurface channels rather than being applied on the surface. This nesting allows the connection mechanism to be hidden within the panel structure itself, providing strong mechanical anchoring while maintaining a clean external appearance.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The filling compound acts as an intermediary material that flows into and fills the subsurface channels, creating a mechanical interlock between adjacent panels. This intermediary substance provides the bonding strength needed to withstand loads while allowing for some movement and stress relief, unlike rigid surface bonding methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If anchoring in a sub-floor is used to secure panels, then the panel stability is improved, but the process becomes extremely complex and leads to high rejects

Engineering Contradiction:
Improvepanel stabilityVSAvoidanchoring complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The invention segments the anchoring function into two parts: the structural support remains with the sub-floor, while the panel-to-panel connection is achieved through independent subsurface channels formed in the panel edge zones. This segmentation eliminates the need for complex sub-floor anchoring systems while maintaining panel stability through the distributed channel network.

Inventive Principle:
Principle #1Segmentation

AI summary

The covering panel (10) has a lower side running in distance to an upper side, and an edge zone connecting the upper and the lower sides. The edge zone has a surface section with a flat upper surface, which is designed for jointless attachment at the corresponding covering panel. Another surface section has an upper surface in which a groove shaped recess extends, and forms a channel section that runs parallel to the upper side of the panel. The former surface section runs perpendicularly to the upper side. An independent claim is also included for a method for displacement of a slab lining with a covering panel.
