Panel Surface Inlay Coating for Flush Multi-Material Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to achieve a smooth, gap-free, and flush transition between different surface materials on panel surfaces, such as combining laminate and solid wood or veneer, due to difficulties in producing exact flushness and the inherent structural differences between materials.
Innovation Solution
The method involves using a second surface material with a homogeneous structure and color, cutting and gluing it to a base plate, followed by grinding to ensure all visible surfaces are flush, and then applying a uniform coating to cover the transition, using known cutting methods and materials like laminate, veneer, or other macroscopically homogeneous materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different surface materials (laminate and veneer) are joined to a base plate, then design versatility and material characteristics are improved, but achieving flush transitions and gap-free surfaces becomes difficult
Solution Approach 1:
The patent applies preliminary action by providing adhesive tape with a release paper before the actual joining process. The adhesive tape is pre-applied to the carrier plate in the desired arrangement, allowing precise positioning of veneer and laminate pieces before gluing. This pre-positioning ensures that different surface materials can be joined with accurate alignment, achieving flush transitions while maintaining design versatility.
Solution Approach 2:
The patent uses adhesive tape as an intermediary element between the carrier plate and the surface materials (veneer and laminate). This adhesive intermediary allows for precise positioning and secure bonding of different materials to the carrier plate, enabling flush transitions and gap-free surfaces while maintaining the ability to create complex designs with multiple material types.
2Shape
If laser cutting is used for veneers, then curve production and surface smoothness are improved, but processing time and equipment complexity increase
Solution Approach 1:
The patent applies universality by using a single laser cutting system to perform multiple functions: cutting veneer pieces, creating curves, producing recesses, and generating indentations. This multi-functional approach allows complex shapes to be created efficiently without requiring separate equipment for each operation, reducing overall device complexity while maintaining shape versatility.
3Adaptability or versatility
If multiple surface materials are combined, then design characteristics are improved, but achieving gap-free transitions becomes impossible
Solution Approach 1:
The patent applies the extraction principle by removing the release paper from the adhesive tape after the surface materials are positioned and glued to the carrier plate. This extraction of the release paper allows the adhesive to fully bond the different surface materials (laminate and veneer) to the carrier plate, ensuring gap-free transitions and eliminating spaces that would otherwise exist between materials with different shrinkage characteristics.

Function Achieved in This Case
This approach enables the creation of a seamless, high-quality surface with different material characteristics, allowing for new design possibilities while maintaining economic viability, particularly in applications like door leaves, furniture, and board games, by ensuring all visible surfaces are on the same plane and uniformly coated.
Implementation Method 1
to connect them to one another and to connect them to a base plate by gluing
Implementation Method 2
The entire surface covered in this way is then ground over so that all visible sides come to lie on a common plane
Implementation Method 3
the surface is provided with a coating as a whole, typically with a clear varnish

AI summary
The method involves homogenously and macroscopically arranging partial pieces from a visible side up to a few tenth of millimeters depth, where the partial pieces comprise a uniform material color. The partial pieces are cut and are glued at a particle board in a desired position. The partial pieces of surface materials e.g. laminated plastic (3) and fiber composite, are ground according to fastening of the particle board and are provided with a coating, where the partial pieces consist of an inlay (2) of different materials.
