Solution Overview

Problem

Existing floor coverings face challenges in seamless installation and long-term stability due to shifting panels and gaps, which affect both aesthetics and fall protection functionality, especially when using pin-like connecting elements.

Innovation Solution

A floor covering system utilizing hard-wearing, elastic panels with a water-permeable design and a connecting element that securely fastens panels together, ensuring a seamless and stable connection through vertical assembly, using EPDM rubber granules and a two-layer structure for enhanced durability and drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If pin-like connecting elements are used to connect floor covering panels, then the panels can be assembled together, but the panels shift against each other over time resulting in gaps and reduced functionality

Engineering Contradiction:
Improveease of assemblyVSAvoidlong-term stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The connecting element is divided into multiple functional parts: a first connecting part that engages with recesses in adjacent panels, and a second connecting part that engages with the last panel. This segmentation allows each part to perform its specific function optimally, preventing panel shifting while maintaining ease of assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting element is inserted into recesses formed in adjacent floor covering panels, creating a nested structure where the connector is housed within the panel assembly. This nesting provides stable connection while allowing for easy insertion and removal during assembly and disassembly.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If connecting elements are used in two directions running transversely to one another, then comprehensive connection is achieved, but difficulties arise when laying the last panel

Engineering Contradiction:
Improveconnection stabilityVSAvoidinstallation difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connecting element is designed to be adaptable in its orientation and engagement method. It can connect panels in multiple directions by engaging with recesses positioned at different locations, allowing flexible adaptation to various panel arrangements including the challenging case of installing the last panel in a transverse direction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connecting element serves multiple functions: it connects panels in longitudinal directions, connects the last panel in transverse directions, and provides lateral stabilization. This multi-functionality eliminates the need for different connector types for different installation scenarios, simplifying the overall installation process.

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

3Device complexity

If floor covering panels are loosely connected or connected with pin-like elements, then assembly is simple, but gaps form over time leading to aesthetic and functional deterioration

Engineering Contradiction:
Improveconnection structure simplicityVSAvoidpanel alignment precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The connecting element features localized engagement points with specific recesses in the panels. This local quality approach creates precise connection points that maintain panel alignment without requiring complex overall structures, achieving both simplicity and precision.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The connecting element automatically maintains panel alignment through its engagement with recesses in adjacent panels. The structure self-adjusts to prevent gaps from forming, eliminating the need for additional alignment mechanisms or complex installation procedures.

Inventive Principle:
Principle #25Self-service

AI summary

The board (10) has a lower side, and an upper side that is provided as a visible face, where the board is made of weather resistant material and provided for formation of a floor covering (50) in connection with a connection element (20) that is arranged on the upper side. A fixation mold enables fixation of the board with the connection element at the lower side in a form-fit manner for guiding the partial joint-less floor covering, where the connection element is made of plastic material. Another fixation mold stabilizes swiveling position of the board relative to the connection element. An independent claim is also included for a method for manufacturing the floor covering.
