Corrugated Composite Wood Panels for Structural Strength and Moisture Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Composite wood panels are heavier, less flex-resistant, and more susceptible to moisture intrusion compared to plywood or solid wood, necessitating a method to create strong, lightweight panels with improved water resistance.
Innovation Solution
A single-step process involving cutting and sorting wood laminae to precise dimensions, applying bonding agents, and forming them into mats for high-pressure pressing to create thin, flexible composite wood webs that can be corrugated for enhanced strength and water resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional composite wood panels are manufactured, then they provide structural strength, but they become heavier and more susceptible to moisture intrusion
Solution Approach 1:
The panel is segmented into a corrugated core structure with flutes and liners, creating a hollow internal architecture that reduces weight while maintaining structural strength through geometric configuration rather than solid material
Solution Approach 2:
The invention uses composite construction with face panels bonded to a corrugated core made from liners and flutes, combining different wood components into a lightweight composite structure that achieves strength-to-weight superiority over traditional solid panels
2Strength
If traditional composite wood panels are manufactured, then they provide structural strength, but they show increased susceptibility to moisture intrusion
Solution Approach 1:
The corrugated core structure with its fluted geometry creates a shell-like configuration that resists moisture penetration, while the bonding agents form protective films at interfaces between components, preventing moisture intrusion into the panel interior
Solution Approach 2:
The corrugated fluted geometry with curved surfaces creates a structure that naturally resists moisture penetration compared to flat panels, as the curved surfaces and air pockets within the flutes provide barriers to moisture migration
3Manufacturing precision
If multi-step manufacturing processes are used, then manufacturing precision can be achieved, but process complexity increases
Solution Approach 1:
The manufacturing process merges multiple operations into a single continuous process where liners and flutes are formed, bonded with adhesive, and assembled into corrugated cores in one integrated production line, reducing process complexity while maintaining precision through automated control

AI summary
A composite wood panel is manufactured from thin wood laminae cut from wood unsuitable for peeler logs or dimensional lumber. At least one bonding agent is applied to the wood laminae, and they are formed into a randomly oriented mat that is compressed into a thin wood web that can be a corrugated web or a flat web that is permanently set in a single press operation.
