RFID Tag Tracking for Tire Mold Defect Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for tracking and identifying tire manufacturing components, such as molds and presses, are unreliable due to environmental harshness, leading to inefficiencies and quality control issues, with 6-10% of tires failing quality checks and defects being difficult to trace back to specific tools.
Innovation Solution
The implementation of specialized RFID tags designed to withstand extreme conditions within tire manufacturing environments, allowing for automated identification and tracking of components, including molds, presses, and bladders, to ensure accurate quality control and defect tracing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual paperwork and engraved numbers are used to identify tire manufacturing components, then the system is simple and easy to implement, but the identification becomes unreliable over time due to environmental harshness causing wear and damage
Solution Approach 1:
The patent replaces mechanical identification methods (engraved numbers on metal surfaces) with an electronic identification system using RFID tags. The RFID tags store identification data electronically and can be read remotely by RFID readers, eliminating the need for physical inspection of engraved numbers that wear and become illegible in harsh manufacturing environments.
Solution Approach 2:
The patent creates an electronic copy of the identification system through RFID tags that contain digital representations of component identifiers. Instead of relying on physical engravings that degrade, the system uses electronic data storage that can be repeatedly read without wear, maintaining identification reliability throughout the component's service life.
2Loss of information
If automated RFID tracking systems are implemented, then identification reliability and traceability improve, but the system complexity and initial cost increase
Solution Approach 1:
The RFID tags serve multiple functions: they identify individual components, track their movement through the manufacturing process, record quality control data, and enable traceability of defects back to specific tools. This multi-functionality consolidates what would otherwise require separate tracking systems into a single integrated solution.
Solution Approach 2:
The RFID system enables automatic identification and tracking without requiring manual data entry or intervention. RFID readers automatically detect and record tag information as components move through the manufacturing line, eliminating the need for operators to manually log data and reducing human error in information tracking.
3Productivity
If manual tracking methods are used, then the system is simple to operate, but productivity decreases due to time-consuming manual processes and frequent press shutdowns for defect investigation
Solution Approach 1:
The RFID system provides immediate feedback by automatically linking quality control results back to the specific mold, press, and bladder used. When a defect is detected, the system instantly identifies the responsible components through RFID tag data, eliminating the need for manual investigation and enabling rapid corrective action to prevent recurrence.
Solution Approach 2:
The system performs preliminary identification and tracking of all components before defects occur. RFID tags are attached to components upfront, and their identification data is continuously recorded throughout the manufacturing process, so when a defect occurs, the information is already available without requiring time-consuming post-defect investigation.
