Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative panels lack sufficient stability, particularly in terms of abrasion resistance and dimensional stability, which affects their durability and adhesion of the decoration layer.
Innovation Solution
A decorative panel with a layered structure that includes a plate-shaped carrier, a decoration substrate, a decorative layer, and a stability layer made of polyurethane with a density greater than 0.8 g/cm3, which enhances the panel's stability characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional layered structure with carrier, decoration substrate, and decorative layer is used, then the panel can be produced with standard manufacturing processes, but the panel lacks sufficient mechanical stability and abrasion resistance
Solution Approach 1:
The patent introduces a stability layer made of polyurethane with density >0.8 g/cm³ between the decorative layer and carrier plate, creating a composite layered structure that combines materials with different properties: the polyurethane layer provides mechanical stability and abrasion resistance, while the decorative layer maintains aesthetic function. This composite approach resolves the contradiction by enhancing reliability without fundamentally changing the manufacturing process complexity.
Solution Approach 2:
The patent specifies a minimum density parameter for the polyurethane stability layer (>0.8 g/cm³), which directly correlates with mechanical stability and abrasion resistance. By controlling this physical parameter, the invention achieves improved reliability while maintaining manageable structural complexity. The density specification ensures optimal balance between stability enhancement and manufacturing feasibility.
2Strength
If the decoration layer is applied directly onto the carrier plate, then the manufacturing process is simplified, but the adhesion of the decoration layer is insufficient
Solution Approach 1:
The polyurethane stability layer acts as an intermediary between the decorative layer and carrier plate, providing a bonding interface that enhances adhesion. This intermediate layer improves the mechanical bond strength and prevents direct contact between the decorative layer and carrier, resolving the adhesion issue while maintaining a relatively simple layered structure that can be produced using standard manufacturing processes.
3Reliability
If a stability layer with high density (>0.8 g/cm³) is added to improve abrasion resistance, then the panel durability is enhanced, but the handling and processing becomes more difficult
Solution Approach 1:
The patent specifies a minimum density threshold (>0.8 g/cm³) for the polyurethane stability layer, which provides sufficient abrasion resistance and mechanical stability without excessive density that would complicate handling. This parameter optimization resolves the contradiction by achieving durability enhancement while maintaining ease of operation within acceptable limits.
