Wood Panel Corrugated Reinforcing Strip Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wood panel manufacturing methods are limited by the thickness and rigidity of reinforcing boards, which restrict production capacity and prevent the creation of panels with shaped side contours featuring small curvature radii.
Innovation Solution
A wood panel manufacturing process that uses a flexible, corrugated reinforcing strip and a finishing edge to enhance compression strength, allowing for higher production efficiency and the ability to produce panels with complex shapes, including rounded portions, by employing an edging machine with specific machining and gluing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid reinforcing boards are used to ensure compression strength, then the panel structural strength is improved, but the production capacity is reduced and frequent machine interventions are required
Solution Approach 1:
The patent replaces rigid reinforcing boards with flexible thin strips that can be continuously fed through the machine. These strips maintain sufficient compression strength while allowing high-speed production without frequent interruptions for board changes.
Solution Approach 2:
The invention changes the physical parameters of the reinforcing element from thick and rigid to thin and flexible, while maintaining adequate compression strength through optimized strip geometry and material selection. This enables continuous production processes.
2Strength
If thick rigid boards are used for reinforcement, then the compression strength is improved, but the ability to manufacture panels with shaped side contours is reduced
Solution Approach 1:
The flexible thin strips can conform to curved and shaped side contours that rigid boards cannot accommodate. This enables the manufacturing of panels with rounded portions and complex geometries while maintaining compression strength.
Solution Approach 2:
The reinforcing element transitions from a static rigid structure to a dynamic flexible form that can adapt to different panel shapes and contours during the manufacturing process, enabling versatility in product design.
3Strength
If rigid reinforcing boards are used, then the compression strength is improved, but frequent machine interventions are required
Solution Approach 1:
The flexible strips enable continuous feeding through the manufacturing machine without interruption, eliminating the need to stop for board changes. This creates a continuous production process that maintains compression strength while minimizing downtime.
Solution Approach 2:
The thin flexible nature of the strips allows them to be continuously supplied from reels through the machine, replacing the discrete rigid board format that requires frequent loading and intervention.
4Productivity
If thin flexible strips are used for reinforcement, then the production capacity is improved, but the compression strength may be reduced
Solution Approach 1:
The patent uses composite construction with multiple thin strips arranged in specific patterns and configurations, combining them with the honeycomb structure and panel sheets to achieve adequate compression strength while maintaining the productivity benefits of thin flexible materials.
Solution Approach 2:
Instead of using single thick boards, the reinforcement is segmented into multiple thin strips distributed across the panel structure, which collectively provide the necessary compression strength while enabling continuous high-speed production.
