Embedded RFID Identifier in Layered Wood Board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching intelligent identifiers to wood boards, such as plywoods, face issues with detachment due to temperature and humidity variations, and there is a lack of integration of such identifiers within layered boards composed of veneer layers.
Innovation Solution
Integrating a remotely readable identifier, such as an RFID transponder, between the veneer layers of a layered board during production, using adhesives like liquid phenolic resin and polyurethane, to ensure the identifier remains operational and protected from mechanical damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive labels are attached to the surface of the wood board, then product information can be provided, but the labels easily detach due to variations in temperature and humidity
Solution Approach 1:
The patent embeds the intelligent identifier within the layered board structure itself, nesting it between veneer layers during manufacturing. This eliminates the need for surface attachment and protects the identifier from environmental factors like temperature and humidity variations that cause adhesive label detachment.
Solution Approach 2:
The intelligent identifier is integrated into the board during the manufacturing process, before the board is put into service. The identifier is placed between veneer layers and bonded with adhesive under heat and pressure, ensuring permanent attachment that withstands subsequent environmental variations.
2Reliability
If an intelligent identifier is integrated between veneer layers during production, then the identifier remains protected and permanently attached, but the manufacturing process becomes more complex
Solution Approach 1:
The patent combines the identifier integration step with the existing veneer layer assembly process. The identifier is placed on a veneer layer along with adhesive, and both are simultaneously pressed and heated in the standard board manufacturing process, merging two operations into one without requiring separate equipment or steps.
3Shape
If a remotely readable identifier is made very thin to be unnoticeable between veneer layers, then aesthetic appearance is improved, but the reading distance and detection capability may be reduced
Solution Approach 1:
The patent changes the physical parameters of the identifier, making it extremely thin (0.05-0.5 mm) while maintaining its functional properties. This allows the identifier to be virtually invisible between veneer layers while still enabling remote reading capabilities through the thin wood material.
