Solid Tire RFID Placement for Tag Protection and Read Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of efficient means for quality control and history management of solid tires for industrial vehicles, particularly in ensuring the protection and response accuracy of embedded RFID tags for product identification.
Innovation Solution
A solid tire design with a tread rubber layer and a base rubber layer, where an RFID tag is embedded near the side surface, within a specific distance range of 0.5 mm to 10.0 mm, and coated with materials like polyphenylene sulfide resin or ceramic for enhanced durability, and short fibers are blended into the base rubber layer to prevent rim slippage and improve protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RFID tag is embedded deeper inside the solid tire to ensure protection, then the protection effect of the RFID tag is improved, but the response accuracy of the RFID tag deteriorates
Solution Approach 1:
The patent optimizes the embedding depth parameter of the RFID tag, specifying that the distance from the side surface should be 0.5mm to 10.0mm. This parameter optimization resolves the contradiction by finding the optimal depth range that provides sufficient protection while maintaining adequate signal response accuracy for quality control and history management.
2Measurement precision
If the RFID tag is embedded too close to the side surface to improve response accuracy, then the response accuracy of the RFID tag is improved, but the protection effect of the RFID tag deteriorates
Solution Approach 1:
The patent establishes a minimum embedding depth of 0.5mm to ensure the RFID tag is sufficiently protected from damage, while simultaneously setting a maximum depth of 10.0mm to maintain response accuracy. This parameter range resolution allows the RFID tag to function effectively for both protection and identification purposes.
3Productivity
If no RFID tag embedding standard is established, then the manufacturing process remains simple, but quality control and history management for each product cannot be performed efficiently
Solution Approach 1:
The patent introduces specific parameter standards for RFID tag embedding (distance from side surface: 0.5mm to 10.0mm) that enable automated quality control and traceability systems. While this adds some manufacturing complexity, it dramatically improves productivity in quality management by allowing efficient identification, tracking, and history management of each solid tire product.

AI summary
In a solid tire including a tread rubber layer on a road contact surface side and a base rubber layer on a rim side and having a side surface extending in a tire radial direction from the tread rubber layer to the base rubber layer, an RFID tag is embedded inside the solid tire, and the RFID tag is disposed near the side surface. When forming an unvulcanized tire by winding a rubber sheet into multiple layers, the RFID tag is inserted between layers of the rubber sheet in the middle of the winding into multiple layers, or the RFID tag and a coating layer are overlaid and attached on a side surface of the unvulcanized tire, and then the unvulcanized tire including the RFID tag is vulcanized in a mold.
