Solution Overview

Problem

Existing modular flooring systems face challenges in accurately positioning the surface pattern layer on the base layer and layer shrinkage during the moulding and curing process, leading to imperfect fits between the base and surface layers.

Innovation Solution

The solution involves a floor tile design with a rim extending around the perimeter of the substrate to form a nest for the laminate layer, using an adhesive to bond the laminate to the substrate, and interlocking tongues and grooves for precise alignment and connection, along with a method involving injection moulding and roller coater machines for manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If layers are moulded and cured in the prior art system, then the flooring tiles are formed, but layer shrinkage occurs causing imperfect fit between base and surface layers

Engineering Contradiction:
Improvefit between base and surface layersVSAvoidlayer dimensions during curing
Core Design Contradiction:
Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

The flooring system is divided into separate base layer and surface layer components that are assembled after individual formation, allowing each layer to be optimised independently and eliminating shrinkage-related fitting problems

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base layer is prepared in advance with pre-formed recesses and positioning features before the surface layer is applied, ensuring accurate alignment and eliminating fit issues that would occur if layers were cured together

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If surface pattern layer is positioned on base layer in prior art, then flooring tiles are assembled, but accurate positioning is difficult resulting in imperfect fit

Engineering Contradiction:
Improvepositioning of surface pattern layerVSAvoidpositioning mechanism
Core Design Contradiction:

AI summary

The present invention provides a tile and method of forming a tile, in which the tile comprises a base substrate and a laminate layer, whereby the substrate has upstanding edges on a top surface thereof, such that the edges define a rim at a perimeter of the substrate for aligning the laminate layer on the top surface of the substrate. The substrate comprises connecting means for engaging with connecting means of a substrate of a further tile to form an interconnected floor system. Engaging the connecting means of a tile with a further tile aligns and positions a side edge of the tile with the side edge of the further tile in a side by side arrangement to provide a grout effect for the tiles when connected.
