Tire Surface Marking via Laser Textured Structural Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for creating surface markings on objects, such as tires, lack effective methods for achieving high contrast through texturing, which is essential for visual differentiation and readability.
Innovation Solution
A method and article featuring a surface with a multiplicity of structural elements having different configurations, including varying dimensions, heights, and outer contours, generated using a two-dimensional intensity distribution with varying intensities, where each intensity range defines the height of the structural elements, and produced through laser machining to create a visually contrasting surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a surface is textured with structural elements of different configurations, then visual contrast is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by systematically varying the height, width, and shape parameters of structural elements on the tire surface. Different parameter combinations create distinct textural patterns that enhance visual contrast for marking purposes, while maintaining manufacturability through controlled parameter ranges
Solution Approach 2:
The patent implements local quality by creating specific regions with unique structural element configurations to form readable markings. Different areas of the tire surface have locally optimized textural patterns that encode information, while other areas maintain uniform patterns for background or different information layers
2Shape
If structural elements with varying dimensions are created, then surface texture complexity increases, but production time increases
Solution Approach 1:
The patent applies segmentation by dividing the tire surface into discrete zones, each containing structural elements with specific configurations. This modular approach allows different textural patterns to be created efficiently without requiring complete reconfiguration of the entire surface, reducing overall production time
Solution Approach 2:
The patent implements preliminary action by pre-defining standardized structural element templates with specific dimension ranges and configurations. These pre-characterized elements can be rapidly deployed to create complex textural patterns without requiring real-time customization, thereby reducing production time while maintaining texture complexity
