Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing panels with reinforced edges are costly, time-consuming, and result in low mechanical stability due to inhomogeneous distribution of reinforcement materials and the need for additional pre-compression steps.
Innovation Solution
A method involving the production of a board by homogeneously spreading glued particulate wooden material onto a conveyor, followed by the application of reinforcement material perpendicular to the conveying direction to form transversal reinforcement zones, which are then pressed to create a board with reinforced edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcement material is applied to spread glued particulate material, then mechanical stability of panel edges is improved, but distribution homogeneity of reinforcement material deteriorates
Solution Approach 1:
The spread glued particulate material is pre-compressed to a density of 0.2-0.6 g/cm³ before reinforcement material application. This preliminary compression creates a uniform matrix structure that ensures homogeneous distribution of subsequently applied reinforcement material, resolving the contradiction between achieving mechanical stability and maintaining distribution homogeneity.
Solution Approach 2:
The patent controls the density parameter of the spread material within a specific range (0.2-0.6 g/cm³) through pre-compression. This parameter optimization enables both homogeneous reinforcement material distribution and adequate mechanical stability of panel edges, simultaneously addressing both requirements.
2Manufacturing precision
If overpressure or vacuum is used to apply reinforcement material, then reinforcement material distribution is improved, but process complexity and time consumption increase
Solution Approach 1:
The patent extracts and eliminates the complex overpressure or vacuum application systems from the production process. Instead, reinforcement material is simply applied to the pre-compressed spread material surface, which naturally ensures homogeneous distribution without requiring additional complex equipment or processes.
Solution Approach 2:
The pre-compressed spread material structure itself provides the necessary conditions for homogeneous reinforcement material distribution. The compressed matrix automatically ensures uniform distribution through its physical structure, making the system self-sufficient and eliminating the need for external overpressure or vacuum systems.
3Manufacturing precision
If pre-compression step is added before reinforcement material application, then reinforcement material distribution is improved, but production time increases
Solution Approach 1:
The patent combines the pre-compression step with the reinforcement material application process. The spread material is compressed to the optimal density range and immediately receives the reinforcement material application in a continuous flow, merging two operations into one integrated process that minimizes time loss while ensuring homogeneous distribution.
Solution Approach 2:
The pre-compression and reinforcement material application are performed in continuous sequence without interruption. The spread material moves continuously through the compression zone and directly into the reinforcement application zone, maintaining continuous useful action and preventing time losses that would occur with separate batch operations.

AI summary
A method is provided comprising: providing particulate material comprising or consisting of particulate wooden material, producing glued particulate wooden material by applying an adhesive to the particulate wooden material, forming a spreading material mat by homogeneously spreading the glued particulate material onto a conveyor on which the spread glued particulate material is conveyed in a conveying direction, and producing a board by pressing the spreading material mat during conveying on the conveyor. Furthermore, a reinforcement material is applied to the spread glued particulate material perpendicular to the conveying direction during forming the spreading material mat and/or after forming the spreading material mat before any pressing of the spreading material mat such that the spreading material mat has at least one longitudinal reinforcement zone containing the reinforcement material. Boards can be obtained, from which panels can be produced having reinforced longitudinal and/or transversal edges.
