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 accuracy in forming edge profiles.

Innovation Solution

A method for manufacturing decorative panels involving a substrate and decorative top layer, where the substrate is mineral or thermoplastic, with edge profiles formed during or prior to dividing operations using cutting or continuous forming processes, allowing precise edge alignment and minimal material loss.

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvemanufacturing processVSAvoidmoisture resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent changes the fundamental material parameter of the substrate from organic fiberboards (MDF/HDF) to inorganic mineral-based materials. This parameter change eliminates moisture sensitivity while maintaining manufacturability through established mineral board production processes.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the top layer extends over bevelled edge portions formed by removing material, then the decorative surface is exposed, but material is wasted and production efficiency decreases

Engineering Contradiction:
Improveedge profile accuracyVSAvoidmaterial waste
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The patent applies preliminary action by forming the bevelled edge profile during the main production process before the panel is completed. The mineral-containing material is shaped with the desired edge profile during manufacturing, eliminating the need for subsequent material removal and preventing material waste.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent extracts the unnecessary step of material removal from the production process. By forming the edge profile directly during manufacturing, the patent removes the wasteful post-processing operation entirely from the production sequence.

Inventive Principle:
Principle #2Taking out (Extraction)

3Manufacturing precision

If vinyl-based floor panels are provided with bevelled edge portions by machining away material, then the edge profile is created, but production time increases and productivity decreases

Engineering Contradiction:
Improveedge profile accuracyVSAvoidproduction speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent merges the edge profiling operation with the main production process. The bevelled edge profile is formed simultaneously with panel manufacturing through integrated molding or shaping operations, eliminating separate machining steps and increasing productivity.

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If the decorative top layer is laminated in a continuous operation with longitudinal edges directed transversely to feeding direction, then lamination efficiency is improved, but edge alignment precision may be compromised

Engineering Contradiction:
Improvelamination speedVSAvoidedge alignment
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent changes the orientation parameter of the panels during lamination. By directing the longitudinal edges of panels transversely to the feeding direction during continuous lamination, the patent optimizes both lamination efficiency and edge alignment precision through improved material flow and positioning.

Inventive Principle:
Principle #35Parameter changes
