Mineral Wool Decorative Floor Panels for Heat-Stable Interlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative panels, particularly those based on MDF/HDF and PVC, suffer from hygroscopicity, poor temperature resistance, flammability, brittleness, and increased risk of breakage due to coupling profile deformation, especially in heating environments, which limits their suitability for floating floor coverings.
Innovation Solution
A decorative panel core composed of mineral wool, such as stone or glass fibers, bonded with a thermosetting binder, providing non-combustibility, thermal stability, and sound dampening properties, with integrally formed coupling profiles to minimize breakage risk and enhance dimensional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PVC based panels are used to replace MDF/HDF panels, then waterproof performance is improved, but temperature resistance deteriorates causing deformation under heating sources
Solution Approach 1:
The patent uses a composite core structure consisting of an inner core layer made of heat-resistant material (such as cementitious board, gypsum board, or fiberboard) and an outer PVC layer. This composite structure combines the waterproof properties of PVC with the high temperature resistance of the inner core material, allowing the panel to withstand heating sources without deforming while maintaining waterproof performance.
2Reliability
If chalk content is increased in PVC panels to reduce cost, then manufacturing cost is reduced, but brittleness increases leading to higher breakage risk
Solution Approach 1:
The patent employs a composite structure with an inner core layer and an outer PVC layer, where the PVC layer can be optimized for cost efficiency with appropriate chalk content while the inner core layer provides structural strength and brittleness resistance. This allows the overall panel to maintain high strength and low breakage risk while keeping manufacturing costs reduced through optimized material composition in each layer.
3Ease of operation
If coupling profiles are profiled to enable panel interlocking, then ease of assembly is improved, but breakage risk of coupling profiles increases
Solution Approach 1:
The patent uses a composite core structure where the inner core layer provides high strength and rigidity to support the coupling profiles, while the outer PVC layer provides ease of profiling and interlocking capability. The reinforced core ensures that coupling profiles maintain high breakage resistance even when profiled for easy assembly, resolving the contradiction between ease of assembly and coupling profile strength.
4Ease of manufacture
If MDF/HDF core layers are used, then ease of manufacture is improved, but fire safety deteriorates due to flammability
Solution Approach 1:
The patent uses a composite structure with an inner core layer made of fire-resistant materials (such as cementitious board, gypsum board, or treated fiberboard) and an outer PVC layer. This combination maintains ease of manufacture through standardized layering processes while the fire-resistant inner core layer provides excellent fire safety properties, preventing flammability issues associated with MDF/HDF panels.
5Temperature
If panel thickness is increased to improve dimensional stability, then temperature resistance is improved, but device complexity increases
Solution Approach 1:
The patent uses a composite core structure with an inner heat-resistant layer and an outer PVC layer, which provides excellent dimensional stability under temperature fluctuations without requiring excessive panel thickness. The layered composite structure achieves thermal stability through material selection rather than increased thickness, thereby maintaining relatively simple panel construction while improving temperature resistance and dimensional stability.
