SPC Tile Imitation Grout Line via Edge Texturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flooring products lack a realistic imitation of grout lines, are labor-intensive to install, especially on vertical surfaces, and do not utilize polyvinyl chloride (PVC) with optimal density or combined with colorants to match tile colors, nor do they feature a densified foam core layer for durability and rigidity.
Innovation Solution
A tile made from synthetic materials with a PVC top layer and densified foam core layer, featuring an exposed portion with a textured surface to simulate a grout line, and an interconnecting mechanism for easy installation on both horizontal and vertical surfaces, using PVC with optimal density and colorants to match the tile's color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional tile installation with cement and grout is used, then a finished floor surface is achieved, but the installation process is labor-intensive and time-consuming
Solution Approach 1:
The grout line imitation structure is pre-formed during tile manufacturing by removing material along the edges to create exposed portions. This preliminary action eliminates the need for post-installation grouting, significantly reducing installation time and labor while maintaining the aesthetic appearance of traditional tiled floors
Solution Approach 2:
The invention extracts the grout line function from the installation process itself and integrates it into the tile structure. By removing material along the edges during manufacturing to create exposed portions with textured surfaces, the grout line effect is built-in, eliminating the separate grouting step that traditionally added labor and time
2Ease of operation
If synthetic flooring products are used to imitate stone or ceramic, then installation is simpler, but they lack a realistic grout line appearance
Solution Approach 1:
The invention applies local quality by creating exposed portions with textured surfaces specifically along the edges of the tile where grout lines would normally appear. The textured surface includes variations in depth, color, and roughness that locally replicate the appearance and feel of real grout, while the rest of the tile maintains its smooth synthetic surface for easy installation
Solution Approach 2:
Colorants are incorporated into the exposed portions during manufacturing to match or contrast with the tile body color, replicating the visual appearance of real grout lines. The color variation and shading in the exposed portions create depth perception that makes the imitation grout line highly realistic
3Strength
If PVC with optimal density is used, then the tile achieves durability and rigidity, but manufacturing complexity increases
Solution Approach 1:
The invention optimizes the density parameter of the PVC material to achieve the desired balance between durability and ease of manufacturing. By selecting the optimal density range, the tile gains sufficient strength and rigidity while remaining manageable during installation. The density parameter is carefully controlled to enable the material removal process that creates the exposed portions without making the manufacturing overly complex

AI summary
A tile that may be used as a covering on a floor, wall, or ceiling surface comprises at least a top section and a core layer may be made from a densified foam material. In most embodiments, but not all, the top section comprises a polyvinyl chloride layer, and may also comprise a wear layer and/or a decorative layer. The tile includes a plurality of sides with an exposed portion(s) formed along at least one of the sides, but in some embodiments also across a middle section of the tile. The exposed portion(s) may be formed on the polyvinyl chloride layer below the tile's top surface at a depth to closely resemble an actual grout line. The tile may further comprise an interconnecting mechanism that at least partially enables an efficient tile installation. The interconnecting mechanism may further contribute to tile's visual appeal by at least partially concealing a connector(s).
