Mechanical Floor Board Coupling for Thick Tiles and Narrow Grout Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor boards with decorative tiles face installation difficulties due to the thickness of the tiles hindering the angling-in coupling process, leading to wider grout lines and reduced aesthetic appeal, and they lack improved waterproof properties and moisture resistance.
Innovation Solution
The floor boards feature mechanical coupling parts with a sideward tongue and recess design that allows easy angling-down installation, reducing the insertion angle and enabling narrow grout lines, while incorporating a decorative surface layer made of rigid materials like ceramic or stone, and treating the substrate edges with water-impermeable agents to enhance waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thick decorative tiles are used on floor boards, then aesthetic appeal and durability are improved, but installation difficulty increases and grout line width increases
Solution Approach 1:
The floor board is segmented into distinct functional layers: a substrate layer and a separate decorative tile layer. This segmentation allows each layer to be optimized independently - the substrate for structural integrity and the tile for aesthetics - while the coupling mechanism bridges these segments to enable installation despite the thickness of the decorative layer.
Solution Approach 2:
A coupling mechanism acts as an intermediary between the substrate and the thick decorative tile. This intermediary component facilitates the connection process by providing a mechanical interface that accommodates the tile thickness, enabling the angling-in installation method to work effectively with thicker decorative layers than would otherwise be possible.
2Strength
If thick decorative tiles are used on floor boards, then aesthetic appeal is improved, but grout line width increases
Solution Approach 1:
The coupling mechanism is pre-configured with specific geometric features (angling surfaces, coupling angles) that guide the installation process. This preliminary design of the coupling geometry enables the tile to be installed at a controlled angle, ensuring that the final position of adjacent tiles creates narrow grout lines even when the tiles themselves are thick.
3Ease of manufacture
If conventional coupling parts are used, then manufacturing simplicity is maintained, but installation quality deteriorates with thick decorative layers
Solution Approach 1:
The coupling mechanism incorporates localized geometric features (angling surfaces, specific contact areas) precisely where needed to interface with the decorative tile. This local optimization of the coupling structure's geometry enables effective installation of thick tiles without requiring complex manufacturing processes for the entire floor board assembly.

AI summary
A floor board including a decorative surface layer applied to a substrate, where the substrate is optionally MDF or HDF material at a side edge thereof, and at least one side edge together with a side edge opposite thereto forming a first pair of opposite side edges of said substrate. The first pair of opposite side edges includes mechanical first and second coupling parts, respectively, allowing the floor board to be coupled at the respective side edges with a similar floor board. Also, a floor board covering consisting of a plurality of the floor boards and a method for manufacturing such floor boards.
