PVC Tile with Exposed Grout Line Imitation
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 a 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
1Manufacturing precision
If traditional tile installation with grout lines is used, then realistic grout line appearance is achieved, but installation labor and time increase significantly
Solution Approach 1:
The patent combines the tile body and grout line into a single integrated structure. The exposed portion of the core layer forms the grout line appearance as an integral part of the tile, eliminating the need for separate grouting operations and reducing installation time while maintaining realistic grout line appearance
Solution Approach 2:
The patent creates a visual copy of a grout line by exposing the core layer through removal of the top layer. This exposed portion replicates the appearance of traditional grout lines without requiring actual grout material, achieving the aesthetic effect while simplifying installation
2Ease of operation
If synthetic flooring materials are used to reduce installation complexity, then installation ease improves, but realistic grout line appearance is lost
Solution Approach 1:
The patent applies different properties to different parts of the tile: the top layer provides a smooth synthetic flooring surface for ease of installation, while the exposed core layer portion creates a textured grout line appearance. This local differentiation allows the tile to simultaneously achieve installation ease and realistic grout line appearance
3Reliability
If PVC material with optimal density is used, then material durability improves, but manufacturing complexity increases
Solution Approach 1:
The patent specifies optimal density parameters for the PVC material (0.95-1.05 g/cm³) to achieve the desired balance between durability and manufacturability. This parameter optimization allows the material to be durable enough for flooring applications while remaining processable through standard manufacturing techniques
4Strength
If densified foam core layer is used to increase rigidity, then tile strength improves, but weight increases
Solution Approach 1:
The patent uses a composite structure combining a densified foam core layer with a PVC top layer. The foam core provides rigidity and structural strength, while the relatively thin top layer contributes minimal weight. This composite approach achieves high tile strength while controlling overall weight through material selection and layer thickness optimization

AI summary
A tile that may be used as a covering on a floor, wall, or other surface comprises a top section, a protective section, and a core layer, and an exposed portion formed along at least one of its sides and structured to represent an imitation but highly realistic looking grout line. In a preferred embodiment, the top section comprises a wear layer, a decorative layer and a polyvinyl chloride layer, and the core layer comprises a densified foam material. The protective section is disposed between the top section and the core layer, and preferably comprises both a protective layer and another decorative layer. The exposed portion structured to represent an imitation grout line is formed within the protective section and is resistant to staining. In some embodiments, the exposed portion is also formed across a middle section of the tile, and may further include an interconnecting mechanism to facilitate installation.
