Veneered Board Bonding With Surface Additive Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing veneered boards have a complex structure and limited improvement in veneer properties, and existing methods to enhance these properties are also ineffective.
Innovation Solution
A method involving applying an additive to the lower face of a veneer, followed by a particulate binder, heating the binder to soften it, and pressing the veneer with a carrier board under increased temperature and pressure to liquefy and cure the binder, allowing the additive to penetrate and enhance the veneer properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure with multiple layers and impregnation steps is used, then the veneer can be fixed to the carrier board, but the manufacturing process becomes complex and the veneer properties are limited
Solution Approach 1:
The patent extracts the additive application step from the traditional impregnation process. Instead of impregnating the veneer with binder solution first and then adding additives, the method applies the additive directly to the veneer surface before binder application, separating these functions to simplify the process while maintaining fixation reliability
Solution Approach 2:
The additive is applied to the veneer surface before the binder is applied. This preliminary action allows the additive to be positioned optimally on the veneer surface, and the binder then serves only as the fixation agent, eliminating the need for complex multi-step impregnation processes
2Reliability
If additives are mixed into the binder, then the veneer can be fixed, but the additive effectiveness is limited and the process remains complex
Solution Approach 1:
The patent segments the functional components: the binder is dedicated solely to fixation, while the additive is applied separately as a distinct layer on the veneer surface. This segmentation allows each component to perform its specific function optimally without the complexity of mixing and the limitations of traditional impregnation methods
Solution Approach 2:
The patent introduces an intermediary step where the additive is applied to the veneer surface before the binder is applied. This intermediary positioning allows the additive to remain effective while the binder provides fixation, avoiding the need to mix additives into the binder which limits additive effectiveness
3Adaptability or versatility
If the additive is applied onto the binder, then the additive can enhance veneer properties, but the additive may mix with the binder and lose effectiveness
Solution Approach 1:
The patent inverts the traditional sequence by applying the additive to the veneer surface before the binder is applied, rather than applying the additive onto the binder as in conventional methods. This inversion ensures the additive remains separate and effective, as it is positioned on the veneer surface where it can enhance properties without mixing with or being diluted by the binder
4Reliability
If multiple impregnation and processing steps are used, then the veneer can be fixed to the carrier board, but the production time increases
Solution Approach 1:
The patent merges the additive application and binder application into a streamlined sequence where the additive is applied first, followed immediately by binder application in the same processing cycle. This merging of steps eliminates the need for separate impregnation cycles and drying steps, reducing production time while maintaining reliable fixation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method produces a simply constructed veneered board with improved veneer properties, ensuring the additive remains on the surface and penetrates into the veneer without mixing with the binder, resulting in enhanced aesthetic and functional effects.
Implementation Method 1
heating the particulate binder, after application onto the veneer, in order to soften the particulate binder
Implementation Method 2
pressing the stack of materials to be pressed into a veneered board by liquefying and curing the binder at increased temperature and increased pressure
