Multilayer Lining Plate with Machinable Perimeter for Dimensional Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vinyl floor coverings exhibit poor dimensional stability due to heat and temperature changes, leading to expansion, deformation, and detachment from support surfaces, making them unsuitable for installations with marked temperature variations, and the introduction of rigid or semi-rigid materials complicates panel connection and adaptation to irregular surfaces.
Innovation Solution
A multilayer lining plate comprising a ductile machinable main layer made of materials like MDF, wood-plastic composite, or PVC, combined with a flexible decorative layer, where the main layer includes magnesium oxide, fibrocement, or mortar with perlite and vermiculite, allowing for machined connecting profiles and adaptation to irregular surfaces through inclined individual parts that can bend and rotate, ensuring stability and connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vinyl material is used for floor coverings, then aesthetic appearance and ease of cleaning are improved, but dimensional stability under temperature changes deteriorates
Solution Approach 1:
The patent applies composite materials by combining vinyl material with a stable support structure (MDF, HDF, or particle board substrate). This composite construction allows the vinyl layer to provide aesthetic and cleaning benefits while the rigid substrate maintains dimensional stability under temperature and humidity variations.
2Stability of the object's composition
If rigid or semi-rigid materials are introduced to improve dimensional stability, then stability is improved, but adaptability to irregular surfaces deteriorates
Solution Approach 1:
The patent applies local quality by creating a layered structure where different materials serve different functions: the rigid substrate (MDF, HDF, or particle board) provides dimensional stability in the core, while the vinyl layer on the surface maintains flexibility and ductility to adapt to irregular floor surfaces. This spatial differentiation of material properties resolves the contradiction between rigidity and adaptability.
3Stability of the object's composition
If rigid materials are used for the main layer, then dimensional stability is improved, but ease of connection and machining deteriorates
Solution Approach 1:
The patent uses composite materials where a rigid substrate (MDF, HDF, or particle board) is combined with a vinyl layer. The rigid substrate provides dimensional stability while remaining machinable and suitable for connecting profiles, resolving the contradiction between rigidity and manufacturability.

AI summary
A multilayer lining plate (100) for essentially horizontal support surfaces such as floors or floor coverings, comprising a main layer (1), including at least one part made of a rigid or semi-rigid material, and a ductile or flexible upper decorative layer (2). The lining plate comprises in the perimeter of the main layer (1) a ductile machinable portion (3) that can be machined to form a connecting profile for the connection of the plate with other plates. The machinable portion (3) is preferably made of medium-density fiberboard (MDF), a wood-plastic composite (WPC) material or polyvinyl chloride (PVC), and the main layer is of magnesium oxide, fibrocement or mortar with perlite and vermiculite.
