Beveled Panel Joints for Continuous Wood Decor Illusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing elongate panels to mimic long floorboards are limited in creating a natural and continuous wood decor appearance, especially in achieving lengths of 2 m to 5 m, as they often result in an unnatural or discontinuous visual effect due to the constraints of impression cylinder sizes and decor repetition.
Innovation Solution
A method involving a large-sized board with elongate panel decors, where the longitudinal and transverse edges are beveled to create a V-shaped joint, allowing for the production of panels that effectively imitate a long floorboard by matching or non-matching decor portions, with bevels introduced before or after division, and optionally using optical scanning for precise edge marking and bevelling.

1Length of moving object
If indirect gravure printing with standard impression cylinder is used, then production efficiency is maintained, but the ability to imitate long floorboards is limited
Solution Approach 1:
The patent divides the floor covering into multiple panels with bevelled edges that create visual segmentation. Each panel contains decor portions that match adjacent panels, and the bevelled edges create shadow effects that simulate the appearance of individual long floorboards rather than short printed segments
Solution Approach 2:
The patent applies different decor configurations to different regions of the panels. Specifically, peripheral regions contain decor portions that match adjacent panels to create continuity, while central regions may have different patterns. The bevelled edges are applied selectively to create localized shadow effects that enhance the perception of length
2Shape
If overlapping decors are used to imitate long floorboards, then visual appearance is improved, but the impression of unnaturally long floorboards occurs in larger rooms
Solution Approach 1:
The patent uses asymmetric decor arrangements where peripheral regions have matching decor portions that create continuity across panel joints, while central regions may have different patterns. The bevelled edges are applied asymmetrically to create visual interest and enhance the perception of individual panel boundaries while maintaining overall continuity
Solution Approach 2:
The patent changes the visual parameters at panel boundaries by introducing bevelled edges that create shadow effects. This parameter change (adding depth and shadow) distinguishes panel joints from the continuous floorboard surface, allowing the human eye to perceive individual panels while maintaining the illusion of long floorboards
3Shape
If bevelled edges are applied to all panels, then production complexity increases, but visual appearance is significantly improved
Solution Approach 1:
The patent segments the application of bevelled edges to specific panel regions (peripheral vs. central) and specific edges (longitudinal vs. transverse), reducing the overall complexity compared to applying bevels to all edges uniformly while still achieving the visual effect of long floorboards

AI summary
The invention relates to a group of elongate panels for imitating a slat, the group comprising at least two slat end panels which have respectively a first short traverse edge and a second short traverse edge and two longitudinal edges and which, when the first respective short traverse edges are placed end to end or are arranged on the end of short traverse edges of at least one elongate intermediate panel, form a slat which has a continuous decoration on the joint of the traverse edges. The panels may have bevel longitudinal edges on their decorated sides, and the second short traversal edge of the respective slat end panel is formed on the decorated side as a bevel transversal edge.
