Heated Damming Belt Assembly for Wood Panel Filler Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for repairing defects on the lateral sides of wood-based panel products, such as plywood, face issues with filler leakage and require lengthy cure times, often involving manual processes and consumables like tape.
Innovation Solution
A heated damming system with a conveyor and heated damming assemblies on both lateral sides of the panel, using a heated belt to contain and cure filler material applied to defects, eliminating the need for tape and reducing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual processes with tape and consumables are used to repair side defects, then filler leakage is reduced, but cure time increases and process complexity increases
Solution Approach 1:
The patent applies heat as a parameter change to accelerate the curing process of filler material. A heating device heats the filler material in the routed defect, reducing cure time from hours to minutes while maintaining reliable filler containment without requiring tape or consumables
Solution Approach 2:
The patent replaces the mechanical containment system (tape and manual processes) with a thermal field system. The heating device creates a controlled thermal environment that both contains and cures the filler material, eliminating the need for mechanical barriers
2Reliability
If manual processes with tape and consumables are used to repair side defects, then filler leakage is reduced, but device complexity and process automation decrease
Solution Approach 1:
The heating device enables the filler material to self-cure through thermal activation. The system automatically heats and cures the filler without requiring manual intervention or consumable materials, simplifying the overall process while maintaining reliable leakage prevention
3Ease of manufacture
If conventional repair systems are used for lateral side defects, then the process is simple, but filler leakage occurs and cure time is lengthy
Solution Approach 1:
The heating device acts as an intermediary between the filler material and the curing process. It provides controlled thermal energy that accelerates curing while the heated damming assembly structure serves as an intermediary containment system, eliminating the need for external tape or consumables
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 system efficiently and automatically repairs defects by containing and curing filler on wood-based panel products, enhancing repair efficiency and eliminating the need for consumables.
Implementation Method 1
the heated damming assembly includes a heated belt (e.g., a metal belt) that is rotated by a drive pulley and heated by a heating device (e.g., a series of heating devices)
Implementation Method 2
the heating device may be an induction coil and the heated damming assembly may include multiple rollers which guide the heated belt along the side of the wood-based panel product
