Tyre Inspection Apparatus Merging 3D Imaging Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated systems for tyre inspection face challenges in accurately recognizing three-dimensional defects due to complex image reconstruction and calibration issues when using separate check stations for high-definition image acquisition.
Innovation Solution
A method and apparatus that acquire high-definition three-dimensional images of both axial halves of a tyre in a single reference system, allowing for precise concatenation and analysis, using a preliminary check station for low-definition imaging and subsequent high-definition imaging in separate check stations, with robotic arms and electronic units for efficient data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate check stations are used for high-definition image acquisition, then device complexity is reduced, but measurement precision deteriorates due to calibration issues and complex image reconstruction
Solution Approach 1:
The patent merges multiple image acquisition systems into a single integrated check station that captures high-definition images of both axial halves of the tyre simultaneously. This eliminates the need for separate check stations and their associated calibration procedures, while maintaining measurement precision through a unified reference system.
Solution Approach 2:
The single check station is designed with multi-functional capabilities to acquire high-definition images of both axial halves of the tyre in one operation. The system incorporates multiple cameras and lighting systems that can capture different views and details simultaneously, replacing what would traditionally require multiple separate stations.
2Measurement precision
If a single reference system is used for high-definition image acquisition, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the image acquisition function into specialized modules within the single check station, with each module optimized for specific imaging tasks. This modular approach manages device complexity by organizing functions into discrete, manageable components while maintaining the benefits of a unified reference system.
3Area of stationary object
If traditional separate check stations are used, then space requirements increase, but reliability of defect detection decreases due to reconstruction complexity
Solution Approach 1:
The patent combines multiple check station functions into a single integrated unit that acquires and processes images of both axial halves simultaneously. This reduces the total space required while improving reliability by eliminating the image reconstruction complexity associated with multiple separate stations.
