Chemically Bonded RFID Tag in Tire Curing Bladder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire curing bladders lack effective remote identification and tracking capabilities, which complicates manufacturing, transportation, and storage processes, and existing RFID solutions are not compatible with the extreme conditions of tire curing environments, leading to potential damage and loss of identification tags.
Innovation Solution
An RFID tag is chemically bonded to the elastomeric body of the tire curing bladder, preferably located in the bead area, and made of similar elastomeric material to enhance bonding and durability, allowing for non-line-of-sight identification and tracking throughout the bladder's life without interfering with thermal diffusivity or stretching capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an RFID tag is attached to the tire curing bladder, then identification and tracking capabilities are improved, but the tag may be damaged or lost due to extreme curing conditions
Solution Approach 1:
The RFID tag is chemically bonded to the elastomeric body of the tire curing bladder, merging the tag into the bladder structure itself. This chemical bonding ensures the tag remains attached and functional throughout the extreme curing conditions, preventing tag loss or damage while maintaining identification capability.
Solution Approach 2:
The RFID tag is constructed using elastomeric material similar to the tire curing bladder, creating a composite structure where the tag and bladder share compatible material properties. This material compatibility enhances the tag's resistance to extreme temperatures and chemical environments during curing.
2Loss of information
If an RFID tag is added to the tire curing bladder, then tracking capabilities are improved, but the device complexity increases
Solution Approach 1:
The RFID tag is integrated directly into the elastomeric body of the bladder through chemical bonding, merging two functions (bladder structure and identification) into a single unified component. This eliminates the need for separate attachment mechanisms, reducing overall device complexity while maintaining full tracking capability.
3Strength
If the RFID tag is made of similar elastomeric material, then chemical bonding is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The RFID tag is constructed using elastomeric material that is similar to or the same as the tire curing bladder material. This material homogeneity enables direct chemical bonding between the tag and bladder during the vulcanization process, creating strong bonds without requiring additional manufacturing steps or materials.
