Tire RFID Layout Relative to Joint Parts for Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire technologies do not consider the optimal positional relationship between electronic components and joint parts of tire constituent members, leading to potential irregularities in tire uniformity and performance.
Innovation Solution
The tire design incorporates an RFID tag positioned within a specific range relative to the joint parts of tire constituent members, such as the inner liner, bead filler, and tread rubber, to ensure optimal alignment and dispersion of joint parts, thereby enhancing uniformity and freedom in arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an electronic component is embedded in the tire without considering the positional relationship with joint parts, then the embedding process is simple, but the tire uniformity and performance are compromised
Solution Approach 1:
The patent applies preliminary action by determining the optimal embedding position of the electronic component before actual embedding. The method involves simulating strain energy distribution, identifying joint parts of tire constituent members, and selecting a position that avoids these joint parts before the embedding process occurs, thereby ensuring tire uniformity while maintaining manufacturing simplicity
Solution Approach 2:
The patent changes the positional parameter of the electronic component embedding location based on strain energy simulation results. By adjusting the embedding position to areas with lower strain energy and away from joint parts, the patent optimizes tire uniformity without complicating the manufacturing process
2Adaptability or versatility
If the electronic component is positioned without considering joint parts, then the arrangement is flexible, but irregularities in tire performance occur
Solution Approach 1:
The patent applies local quality by identifying specific regions within the tire structure that are suitable for electronic component embedding. By analyzing strain energy distribution and joint part locations, the patent designates optimal local zones for embedding that maintain both arrangement flexibility and performance reliability
Solution Approach 2:
The patent uses simulation to create a virtual model of strain energy distribution and joint part positions before actual embedding. This copying of the physical tire structure into a simulation model allows for optimal position selection that ensures reliability while maintaining arrangement flexibility

AI summary
Provided is a tire which takes into account positional relationships between joint parts of a plurality of tire constituent members and an electronic component. A tire 1 comprises: a plurality of annular tire constituent members respectively having joint parts formed by joining one end and another end of each member; and an RFID tag 40 serving as an electronic component. The plurality of annular tire constituent members respectively having joint parts include an inner liner 29 that covers a tire inner cavity surface, and at least two tire constituent members different from the inner liner 29. The RFID tag 40 is disposed within a range of less than 90° around a tire rotation axis, relative to the positions of the joint parts of the inner liner 29.
