Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wooden floor coatings either require frequent maintenance due to low wear resistance and susceptibility to deformation from small-area loads, or provide high wear resistance but at the cost of reduced substrate perceptibility and increased brittleness.
Innovation Solution
A transparent, organic binder-based coating with vibration damping properties, incorporating specific additives and particles, applied in a range of 60 μm to 200 μm thickness to enhance wear resistance and prevent deformation while maintaining substrate perceptibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic resin-based coatings are applied to achieve high wear resistance, then wear resistance is improved, but substrate perceptibility deteriorates and brittleness increases
Solution Approach 1:
The patent modifies the coating composition by incorporating rubber particles (5-50 μm) into the synthetic resin matrix, changing the physical parameters of the coating material to achieve both high wear resistance and flexibility that maintains substrate perceptibility
Solution Approach 2:
The patent creates a composite coating material combining synthetic resin with rubber particles, where the resin provides wear resistance and the rubber particles provide flexibility and impact absorption, resolving the contradiction between hardness and perceptibility
2Ease of operation
If oil and wax-based coatings are applied to maintain substrate perceptibility, then substrate perceptibility is improved, but wear resistance deteriorates and maintenance frequency increases
Solution Approach 1:
The patent combines synthetic resin (for wear resistance) with rubber particles (for flexibility and impact absorption), creating a composite coating that maintains substrate perceptibility while providing high wear resistance, eliminating the need for frequent maintenance
3Strength
If angular objects fall on the coating surface, then the coating is subjected to small-area loads, but deformation occurs that cannot be removed
Solution Approach 1:
The patent incorporates rubber particles into the coating formulation before application, creating a cushioning effect that absorbs impact energy from falling objects, preventing deformation before it occurs
Solution Approach 2:
The synthetic resin-rubber composite structure provides both strength to resist small-area loads and flexibility to prevent permanent deformation, making the coating self-healing regarding impact marks

AI summary
The invention relates to a floor panel (1) comprising a slab-shaped substrate (2) made of wood and/or wood-based material, wherein at least the upper side of the substrate is provided with a decorative finish, preferably a decorative wood finish, and with a transparent, closed coating (3) based on an organic binder, this coating being applied to the decorative finish and defining the exposed upper side of the floor panel. According to the invention, when a sample of the floor panel is subjected to a pendulum damping test according to EN ISO 1522, the coating (3) of the floor panel according to the invention produces an oscillation damping in the range from 8 s to 22 s. The coating according to the invention allows the wooden floor covering to be perceived satisfactorily by the user, has a comparatively high wear resistance combined with low maintenance requirements and substantially prevents deformations of the wooden floor covering resulting from small-area loading.
