Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laminate and vinyl-based floating floor panels suffer from moisture sensitivity, noise development due to ticking, and material density issues, while existing manufacturing methods lack efficiency and precision in forming edge profiles.
Innovation Solution
A method for manufacturing decorative panels using a thermoplastic substrate and top layer, where lower edge areas are formed prior to or during a dividing operation, utilizing cutting and indenting processes to create precise edge profiles with minimal material loss, allowing for continuous top layer extension and efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If laminate floor panels are manufactured with MDF or HDF substrate, then the panels can be produced with standard materials and processes, but the panels become moisture-sensitive and develop ticking noises during use
Solution Approach 1:
The patent changes the material parameter from traditional moisture-sensitive MDF/HDF substrates to PVC-based synthetic materials that are inherently moisture-resistant, eliminating the ticking noise problem while maintaining manufacturability through standard extrusion and lamination processes
Solution Approach 2:
The patent uses composite construction with a PVC-based substrate combined with a decorative top layer, creating a material composition that provides both moisture resistance and aesthetic functionality, resolving the contradiction between ease of manufacture and reliability
2Manufacturing precision
If the top layer is extended over bevelled edge portions by compressing the core material, then the top layer extends uninterruptedly from the global surface to and over the bevelled edge portion, but the manufacturing process becomes more complex
Solution Approach 1:
The patent performs the indenting operation to create lower edge areas before the dividing operation, preparing the material in advance so that subsequent cutting produces precise edge profiles without requiring complex post-processing or material compression steps
Solution Approach 2:
The patent separates the edge profile formation into distinct operational phases: first creating the lowered edge area through indenting, then completing the edge definition through dividing, which simplifies each individual step while achieving the overall precise edge profile
3Productivity
If the lower edge area is formed after the dividing operation, then the production process follows traditional sequencing, but material deformation and waste cannot be concentrated in removable portions
Solution Approach 1:
The patent creates the lower edge area through indenting before the dividing operation, allowing material deformation to occur in areas that will subsequently be removed or are less critical, thereby minimizing waste of valuable material while maintaining production efficiency
Solution Approach 2:
The patent applies local deformation through indenting at specific edge areas rather than uniformly across the entire material, concentrating material modification only where needed for the lower edge area, which reduces overall material waste and improves production efficiency
