Embedded Tire Communication Module for Visible Recycling Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The recycling of tires with embedded communication devices is hindered by the degradation of rubber quality due to resin inclusion and the difficulty in separating metal components, making it challenging to confirm if the entire communication device is removed during the recycling process.
Innovation Solution
A tire design featuring a covered communication device with a distinct covering body that includes a rubber composition with a low dielectric constant and a different-colored outer surface layer, allowing for easy identification of the device's removal by creating a distinguishable distinction portion when hollowed out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication device is embedded in the tire body, then the tire can provide communication functions, but it becomes difficult to confirm whether the entire communication device is removed during recycling
Solution Approach 1:
The covering body includes a distinction portion with a different color or shade from the surrounding tire body. This color difference allows visual detection of the covering body's location and boundaries, making it easy to confirm whether the entire communication device has been removed during recycling by simply observing the cross-sectional view.
2Ease of repair
If the communication device is removed by hollowing out the tire, then the communication device can be separated, but it is difficult to confirm whether the entirety of the communication device is included in the hollowed out portion
Solution Approach 1:
The distinction portion of the covering body has a different color or shade that remains visible after hollowing out. When the tire is cross-sectioned, the colored distinction portion allows workers to visually confirm whether the entire communication device has been extracted, preventing residual device parts from being left behind.
Solution Approach 2:
The covering body acts as an intermediary element between the communication device and the tire body. It provides a visual interface (through the distinction portion) that mediates the confirmation process, allowing workers to verify complete device removal without needing to inspect the device itself.
3Productivity
If resin and metal components are included in the recycling process, then the communication device can be processed, but the quality of recycled rubber degrades and separation requires time and effort
Solution Approach 1:
The covering body is segmented into a distinction portion with different material composition or coloration from the surrounding tire body. This segmentation allows for easier separation during recycling, as the distinct portion can be identified and handled separately, reducing contamination of the recycled rubber and simplifying metal component recovery.

AI summary
A tire according to the present disclosure includes a tire body and a covered communication device at least a part of which is embedded in the tire body. The covered communication device includes a communication device and a covering body that covers the periphery of the communication device. The covering body includes a distinction portion that is distinguishable from a portion located around the covering body, of the tire body, in a cross-sectional view in a plane passing through the covered communication device.
