Embedded RFID in Wood-Particle Panels to Prevent Label Detachment
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 either use adhesives or require housing recesses which are prone to detachment.
Innovation Solution
Integrate a radio-frequency identification device within the wood-particle panel during manufacturing, using resin-coated layers without adhesives, ensuring the device is embedded between layers of the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive labels are used to describe product specifications on wooden panels, then product information can be provided, but the labels are subject to frequent detachments following variations in temperature, humidity, and wear
Solution Approach 1:
The patent merges the identification device with the panel structure by embedding the RFID tag within the wood particle panel matrix during manufacturing. This integration eliminates the separate adhesive label component, combining the identification function directly into the panel body to prevent detachment while maintaining manufacturing feasibility through existing panel production processes
2Reliability
If intelligent identifiers are arranged between layers of veneer, then identification can be provided, but the identifier is subject to detachment following variations in temperature, humidity, wear, impact, etc.
Solution Approach 1:
The patent integrates the RFID identification device directly into the wood particle panel matrix rather than placing it between veneer layers. This merging of the identification device with the panel substrate eliminates the risk of detachment between layers while avoiding the added structural complexity of multi-layer veneer constructions
Solution Approach 2:
The patent uses homogeneous wood particle material throughout the panel, with the RFID tag embedded within the same particle matrix. This homogeneous structure ensures uniform attachment characteristics and eliminates the detachment risks associated with interfaces between different materials or layers
3Reliability
If a recess is created in the wooden panel to house the RFID element, then identification can be provided, but the RFID element is subject to repeated stress that could cause it to become detached
Solution Approach 1:
The patent extracts the need for a separate housing recess by embedding the RFID tag directly within the wood particle panel matrix. This eliminates the recess structure and its associated stress concentration points, preventing RFID element detachment while avoiding the additional processing steps required to create and finish recesses
Solution Approach 2:
The patent combines the RFID tag housing function with the panel matrix itself, eliminating the need for separate recess structures. The wood particle panel serves dual purposes as both the structural component and the identification device housing, reducing overall device complexity
4Loss of information
If adhesive labels are used on panel surfaces, then product specifications can be described, but the labels detach following mechanical and climatic stress
Solution Approach 1:
The patent merges the information storage function with the panel structure by embedding the RFID tag within the panel matrix. This integration ensures that product identification information remains permanently attached even under mechanical and climatic stress, eliminating the detachment problem while maintaining full information visibility
