Electronic Tyre Identification for Automated Cold Retreading Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing vehicle tires for cold retreading are labor-intensive, time-consuming, and prone to errors due to the lack of knowledge about the specific layer structure and varying dimensions of worn tires, making automated tread removal difficult.
Innovation Solution
A method utilizing an electronic identification unit with control information stored on a vehicle tire to guide the removal of the tread and sidewalls, enabling automated and efficient preparation for cold retreading by ensuring the preservation of the intact carcass and belt layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated tread removal is attempted without knowledge of specific layer structure, then productivity increases, but manufacturing precision deteriorates due to inability to preserve belt layers
Solution Approach 1:
The patent applies preliminary action by equipping tires with electronic identification units (RFID tags) during the original tire manufacturing process. These units store precise information about the tire's layer structure, belt layer positions, and recommended removal parameters. When the tire reaches the retreading facility, this pre-stored information is automatically read and used to guide the automated removal process, eliminating the need for manual inspection while ensuring precise preservation of belt layers.
2Manufacturing precision
If manual inspection is used to determine removal contour, then manufacturing precision improves, but loss of time increases due to labor-intensive work
Solution Approach 1:
The patent replaces the mechanical/manual inspection system with an automated electronic information system. Instead of workers manually measuring and determining removal contours, the system automatically reads layer structure data from the electronic identification unit and uses this information to control automated removal devices. This substitution maintains high precision in determining removal contours while dramatically reducing the time required for the preparation process.
3Adaptability or versatility
If external service providers perform tread removal, then adaptability improves for different tire types, but reliability deteriorates due to limited knowledge of tire structure
Solution Approach 1:
The patent introduces an intermediary solution in the form of electronic identification units that act as information carriers between the original tire manufacturer and the external retreading service provider. The RFID tags store standardized information about layer structure and removal parameters, serving as a reliable intermediary that bridges the knowledge gap. This allows external providers to handle diverse tire types reliably without needing specialized knowledge of each tire's internal structure, as all necessary information is encoded in the electronic tags.
