Unvulcanized Rubber Strip RFID Integration via Single-Web Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing material strips with integrated RFID chips require significant space and complexity due to the need for separate unwinding and feeding of two material webs, which complicates the manufacturing process.
Innovation Solution
A method where a single material web of unvulcanized rubber is unwound and cut into two pieces, with an RFID chip placed between them, allowing for simplified production by eliminating the need for a second unwinding device and enabling space-efficient manufacturing by using only one material web, which are then connected through adhesive contact or lamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate material webs are unwound and laminated to integrate RFID chips, then the RFID chip integration is achieved, but the space required for production facilities increases and the workflow becomes more complex
Solution Approach 1:
The patent merges the function of two separate material webs into a single material web. The single web is folded back onto itself to create the sandwich structure (first piece, RFID chip, second piece) that was previously achieved by laminating two separate webs. This eliminates the need for a second unwinding device and reduces production facility space while maintaining RFID chip integration capability.
2Reliability
If two separate material webs are unwound and laminated to integrate RFID chips, then the RFID chip integration is achieved, but the device complexity and workflow complexity increase
Solution Approach 1:
The production process is simplified by combining two separate material web handling operations into one. A single unwinding device feeds one material web that is folded back onto itself, eliminating the complexity of coordinating two separate unwinding and lamination operations. The folding mechanism replaces the more complex two-web lamination system.
3Reliability
If two separate material webs are unwound and laminated to integrate RFID chips, then the RFID chip integration is achieved, but the number of unwinding devices and feeding operations increases
Solution Approach 1:
The patent combines the unwinding and feeding functions for two material webs into a single unwinding device that handles one material web. The folded configuration of the single web replaces the need for two separate webs, reducing the number of unwinding devices from two to one and simplifying the feeding operation while maintaining the sandwich structure formation.

Function Achieved in This Case
This approach reduces space requirements and simplifies the manufacturing process by using a single material web, allowing for efficient production of material strips with integrated RFID chips, which can be easily integrated into tire production, while maintaining the functionality of the RFID chip for data exchange and energy supply.
Implementation Method 1
The material pieces can be bonded together by placing them on top of each other, provided they have sufficiently adhesive contact surfaces.
Implementation Method 2
the first and second pieces can also be additionally bonded or laminated to create a material strip with an integrated electronic component
