Optical Code Panel for Tire DOT Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for applying and verifying the DOT code on tires during vulcanization are inefficient due to the need for frequent panel changes, potential reading errors, and the challenging environmental conditions of the vulcanization mold area, leading to production inefficiencies and risks of incorrect tire production.
Innovation Solution
Incorporating an optical code on the panel that encodes the DOT information, allowing for pre-mount verification using OCR or optical readers in a controlled environment, ensuring accurate panel alignment and reducing human error, and enabling automated checks before tire production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual visual verification of DOT code is performed, then human inspection is possible, but reading errors and production inefficiency occur
Solution Approach 1:
The patent replaces manual visual inspection with an automated optical reading system. An optical reader equipped with a camera and image processing unit automatically captures and verifies the DOT code on the panel, eliminating human reading errors and significantly improving verification speed and productivity.
Solution Approach 2:
The system performs self-verification by automatically capturing the DOT code image, processing it through image recognition algorithms, and validating the information without requiring human intervention. The panel itself provides the verification data through its encoded DOT information.
2Adaptability or versatility
If panel changes are performed frequently to update DOT codes, then current production requirements are met, but production inefficiency increases
Solution Approach 1:
The patent pre-encodes the DOT code information onto the panel in an optical format before the panel is mounted on the mold. This preliminary encoding allows the DOT information to be verified automatically without requiring panel changes during production, maintaining adaptability while eliminating the productivity loss from frequent panel changes.
Solution Approach 2:
The system creates an optical copy (image) of the DOT code on the panel and verifies this copy automatically. The optical reader captures the DOT information as an image, processes it through image recognition, and validates it without physical panel changes, thus maintaining code updates while preserving production continuity.
3Extent of automation
If optical code is added to panel, then automated verification is enabled, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional integrated system where the optical reader performs multiple functions: capturing the DOT code image, processing the image through recognition algorithms, validating the information, and controlling the verification process. This universal approach enables high automation while managing complexity through consolidation of functions into a single integrated device.
