Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for integrating radio-frequency electromagnetic wave transceivers, such as RFID and NFC tags, onto paper or cardboard products externally expose the transceivers, making them visible and susceptible to malicious removal.
Innovation Solution
A method involving the internal integration of transceivers within paper-based products by applying gluing means to ensure the transceivers are embedded between two sheets of paper or cardboard, with controlled temperature and pressure conditions to prevent damage and ensure adhesion, followed by a precise cutting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transceiver is applied externally to the paper product by gluing, then the transceiver is visible and accessible, but it becomes susceptible to malicious removal and reduces product security
Solution Approach 1:
The transceiver is nested between two sheets of paper or cardboard, with the second sheet folded over to enclose it. This nesting approach embeds the transceiver within the product structure, making it invisible and resistant to removal, thereby resolving the security vulnerability of external attachment.
Solution Approach 2:
The method uses flexible paper or cardboard sheets to enclose the transceiver. The second sheet is folded over the transceiver and adhered to the first sheet, creating a flexible encapsulation that protects the transceiver while maintaining product integrity and preventing unauthorized access.
2Reliability
If the transceiver is embedded within the paper product, then it is protected from removal, but the manufacturing process becomes more complex requiring controlled temperature and pressure
Solution Approach 1:
The manufacturing process employs controlled temperature and pressure parameters during the folding and adhering steps. The paper sheets are heated to activate the adhesive and pressed to ensure proper bonding, with specific parameters (temperature not exceeding 55°C, pressure applied during folding) that protect the transceiver while achieving secure encapsulation.
Solution Approach 2:
The adhesive is applied to the first sheet before the transceiver is positioned and the second sheet is folded over. This preliminary application of adhesive ensures that when folding occurs, the transceiver is already secured in place, simplifying the encapsulation process and ensuring consistent results.
3Strength
If high temperature and pressure are applied during manufacturing, then adhesion is improved, but the transceiver may be damaged
Solution Approach 1:
The process specifies that the paper sheet temperature does not exceed 55°C during adhesive activation, and pressure is applied in a controlled manner during folding. These parameter constraints ensure sufficient adhesion strength while preventing thermal or mechanical damage to the transceiver, maintaining its functionality.
Solution Approach 2:
The transceiver is positioned between two protective paper sheets before adhesive application and folding. This sandwich structure provides cushioning and protection during the manufacturing process, preventing direct exposure to excessive pressure or temperature that could damage the transceiver while still allowing adequate adhesion.
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 method effectively embeds transceivers within paper products, providing protection and ensuring they remain undetectable, maintaining functionality while preventing damage during manufacturing.
Implementation Method 1
The two sheets are brought into contact with each other with the interposition of a substance having adhesive properties
Implementation Method 2
The two sheets are brought into contact with each other with the interposition of the gluing means only if the temperature of the latter is not higher than 55°C
Implementation Method 3
The sheets are pressed against each other so as to ensure the grip of the glue

AI summary
The invention relates to a method for manufacturing a product mainly made of paper including at least one radio-frequency electromagnetic wave transceiver adapted both to receive at least a first predefined signal and to emit, upon receiving said first signal, at least a second signal, also predefined. To implement the method object of the invention, it is first necessary to prepare at least two sheets, mainly made of paper, such as two sheets of paper. Glue is applied to one of the sheets, the transceiver, such as an RFID tag or an NFC tag, is applied to the other sheet. The two sheets are then coupled, calendered and subjected to a finishing cut. The transceiver is programmable in any step of the method object of the invention.
