MgO Flooring Plank Bevel Forming During Cement Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming bevels in magnesium oxide (MgO) flooring planks are time-consuming, labor-intensive, and inefficient, as MgO planks are brittle and cannot be mechanically pressed or cut like softer materials.
Innovation Solution
A process that utilizes the curing time of a cement binder in the MgO core layer to concurrently shape bevels by applying a patterned plate during the curing process, allowing the bevel pattern to penetrate and transfer into the cement binder as it hardens, forming precise bevels without mechanical pressing or cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical pressing or cutting methods are used to form bevels in MgO flooring planks, then the bevels can be created, but the process becomes time-consuming, labor-intensive, and inefficient due to the brittle nature of MgO material
Solution Approach 1:
The bevel pattern is pre-formed on a plate before the MgO plank is placed upon it. During the curing process, the uncured MgO material is pressed into the pre-formed bevel pattern, transferring the bevel geometry directly onto the plank surface. This eliminates the need for time-consuming post-curing mechanical cutting or pressing operations.
Solution Approach 2:
The bevel pattern is copied from a master plate onto the MgO plank surface during curing. The plate contains a pre-formed bevel pattern that is replicated onto the uncured MgO material through pressure application, creating an accurate copy of the desired bevel geometry without requiring complex mechanical cutting tools.
2Manufacturing precision
If mechanical cutting methods are used to form bevels, then bevels can be created, but additional steps are required to smooth or shape the bevels along each individual plank
Solution Approach 1:
The bevel pattern is pre-formed on the plate with precise geometric dimensions before the MgO plank is placed upon it. The pre-formed pattern includes all necessary smoothing and shaping features, eliminating the need for additional post-processing steps to achieve the desired bevel geometry.
Solution Approach 2:
The precise bevel pattern from the master plate is copied onto the MgO plank surface during curing. The copying process transfers the exact bevel geometry including smooth transitions and precise angles directly onto the plank, eliminating the need for separate smoothing operations.
3Productivity
If traditional bevel formation methods are used, then bevels can be created on flooring planks, but the process requires separate operations for each plank
Solution Approach 1:
Multiple MgO planks are stacked together with patterned plates placed between them, allowing the bevel pattern to be transferred to all planks simultaneously in a single pressing operation during curing. This merges multiple individual bevel formation operations into one batch process, significantly improving productivity while maintaining simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Efficiently creates bevels in MgO flooring planks with precise control over shape and location, reducing time and labor while maintaining the structural integrity of the planks.
Implementation Method 1
the inherent time it takes for a cement binder in the core layer to harden and cure
Implementation Method 2
A pressure is preferably applied to the plate during the curing process to ensure the bevel pattern on the plate sufficiently penetrates, and is thus transferred to, the surface of the cement binder as it cures

AI summary
The present disclosure provides a novel technique for creating bevels along the edges of flooring planks having a hard and rigid core layer, preferably comprising a magnesium-based cement or other type of curable binder material. The disclosed embodiments use the inherent time it takes for a cement binder in the core layer to harden and cure to concurrently shape bevels along one or more edges of the rigid core layer for one or more flooring planks.
