Embedded RFID Wood-Particle Panel for Durable Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wood-particle panels lack an integrated identification device that ensures continuous traceability without detachment due to mechanical and climatic stress, and existing solutions with adhesive labels or recesses for RFID tags are prone to detachment.
Innovation Solution
Integrate a radio-frequency identification device within the wood-particle panel during manufacturing, using resin-coated layers without glues or adhesives, ensuring the device is embedded between layers of the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive labels or RFID tags are attached to the panel surface or in recesses, then identification functionality is provided, but the identification device detaches due to mechanical and climatic stress
Solution Approach 1:
The identification device is integrated directly into the panel structure by embedding it within the wood particle matrix during manufacturing. The resin coating on particles creates binding zones that mechanically interlock with the identification device, merging the identification function with the panel itself rather than attaching it as a separate component. This eliminates detachment issues while maintaining continuous identification capability.
2Reliability
If adhesive labels are used on panel surface, then identification is provided, but labels detach following temperature and humidity variations
Solution Approach 1:
The identification device is nested within the panel structure, embedded in the wood particle matrix. The resin-coated particles surround and encapsulate the identification device, creating a protective matrix that shields it from climatic stress while maintaining its identification function. This nested configuration protects the identification device from temperature and humidity variations that cause surface label detachment.
3Reliability
If recesses are created for RFID tags, then identification device housing is provided, but production complexity increases
Solution Approach 1:
The panel is formed by depositing resin-coated wood particles in layered sequences during manufacturing. The identification device is embedded within these segmented layers, with resin-coated particles creating discrete binding zones. This segmentation approach integrates the identification device into the natural layering process without requiring separate recess creation steps, maintaining production simplicity while ensuring device retention.

AI summary
A panel made of wood particles is described, equipped with at least one identification device integrated in the panel, wherein the panel includes three or more layers of resin-coated material, two fine-grained outer layers and one or two coarse-grained inner layers; and a relative method for producing said panel which allows the arrangement of layers of fine resin-coated material, the deposition of layers of coarse resin-coated material, alternating with at least an arrangement of a plurality of identification devices on said layers of fine and/or coarse resin-coated material.
