Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching RFID tags to collar pieces in cigarette packs are time-consuming and inefficient, especially for large batches, due to the use of multiple material layers which increase costs and thickness.
Innovation Solution
A method involving a collar material web where an RFID antenna is formed directly onto the surface using electrically conductive particles, followed by attaching an RFID IC, eliminating the need for additional adhesive layers and simplifying the process for larger batches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the RFID tag is attached directly onto the collar piece using conventional methods, then the RFID tag can be secured onto the collar piece, but the process is very time consuming and inefficient for large batches
Solution Approach 1:
The patent merges the RFID tag and collar piece into a single integrated component by forming the antenna directly on the collar piece material web during the manufacturing process. This eliminates the separate attachment step and integrates RFID functionality into the collar piece production line, significantly improving productivity and reducing time loss.
Solution Approach 2:
The RFID antenna is formed directly onto the collar material web during the manufacturing process, before the collar piece is cut and assembled. This preliminary integration of the RFID tag into the collar piece production process eliminates subsequent attachment steps and enables high-volume production without additional time loss.
2Reliability
If multiple material layers are used to attach the RFID tag onto the collar piece, then the RFID tag can be securely attached, but material costs increase and the collar piece thickness increases
Solution Approach 1:
The patent extracts and eliminates the unnecessary intermediate material layers (siliconized backing paper, release liner, adhesive layers, face material layer) from the RFID tag attachment process. By forming the antenna directly on the collar material web, only the essential conductive material and substrate remain, reducing complexity while maintaining secure attachment.
Solution Approach 2:
The RFID antenna structure is merged directly with the collar material web through direct formation during manufacturing, eliminating the need for separate adhesive layers and backing materials. This integration reduces the total number of material layers from multiple layers to essentially two layers (conductive material and substrate).
