1Productivity
If conventional methods are used to assemble tire-wheel assemblies, then human oversight and capital investment are required, but efficiency in determining uniformity is reduced
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an optical imaging system. Imaging devices capture multiple images of the tire as it rotates, and a computer processes these images to automatically determine uniformity, eliminating the need for manual mechanical measurement and reducing capital investment requirements.
Solution Approach 2:
The patent creates optical copies (images) of the tire surface instead of direct physical measurement. By capturing multiple images at different rotational positions and using computational algorithms to analyze these copies, the system determines uniformity without requiring complex physical measurement equipment or manual intervention.
2Measurement precision
If direct contact methods are used to measure tire uniformity, then measurement precision is achieved, but cost and complexity increase
Solution Approach 1:
The patent introduces light as an intermediary to measure tire uniformity. Imaging devices capture the tire's appearance from multiple angles as it rotates, and computational algorithms process these visual data to determine road force uniformity. This optical intermediary approach achieves precise measurements without requiring direct physical contact or complex measurement systems.
Solution Approach 2:
The patent substitutes mechanical measurement systems with an optical-computational system. Instead of using physical sensors or manual measurement tools that require direct contact with the tire, the system uses imaging devices and computer algorithms to non-contactually determine uniformity, reducing both cost and system complexity while maintaining precision.
