Tyre Surface Inspection Device 2D 3D Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current quality control methods for tyres in production lines are cumbersome, requiring excessive time and space, and lengthening cycle times and production costs due to the need for separate acquisitions of 2D and 3D images of tyre surfaces, which are not efficiently combined for inline inspection.
Innovation Solution
A device combining 2D and 3D image acquisition systems on a single support frame, allowing simultaneous acquisition of images by moving the tyre surface along a translation plane within the depth of field of both systems, enabling compact and efficient inline inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate acquisition systems for 2D and 3D images are used, then comprehensive surface analysis is achieved, but device dimensions and analysis time increase
Solution Approach 1:
The patent combines 2D and 3D image acquisition systems into a single integrated device with a common support frame. The 2D camera system and 3D laser scanner are mounted on the same structure, allowing simultaneous operation from the same position, thereby reducing overall device dimensions while maintaining comprehensive surface analysis capability.
Solution Approach 2:
The integrated device performs multiple functions (2D imaging, 3D scanning, defect detection) through a single multi-functional system. The support frame structure serves as a common platform for both acquisition systems, and the synchronized operation enables the device to capture both 2D and 3D data in one inspection cycle, eliminating the need for separate dedicated systems.
2Measurement precision
If separate acquisition systems for 2D and 3D images are used, then comprehensive surface analysis is achieved, but analysis time increases
Solution Approach 1:
The 2D and 3D image acquisition systems operate simultaneously and continuously during a single inspection cycle. The synchronized triggering mechanism ensures that both cameras capture images at the same moments when the tyre surface is in the field of view, eliminating sequential processing delays and achieving continuous data collection for comprehensive analysis.
Solution Approach 2:
The system performs preliminary synchronization of both acquisition systems before actual inspection begins. The control unit pre-configures the simultaneous operation parameters, ensuring that both 2D and 3D data collection are ready and coordinated from the start of the inspection process, thereby minimizing setup time and maximizing analysis efficiency.
3Measurement precision
If separate acquisition systems for 2D and 3D images are used, then complete surface coverage is achieved, but production costs increase
Solution Approach 1:
By merging 2D and 3D acquisition systems into a single integrated device with shared components (support frame, mounting mechanisms, control unit), the patent reduces the total number of separate systems needed. This consolidation lowers manufacturing costs through reduced material requirements, simplified assembly processes, and decreased maintenance needs while maintaining complete surface coverage capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach halves the time required for analysis and reduces the device's dimensions, enabling faster and more cost-effective inline quality control of tyres by synchronizing the movement of the tyre surface with image acquisition, allowing for both 2D and 3D imaging of the same surface region.
