Tire Sidewall Pattern Segmentation With Luminance Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire designs lack the ability to effectively broaden the width of expression in decorative sections, limiting aesthetic appeal.
Innovation Solution
The tire features large pattern areas on its outer surface, comprising first and second pattern areas with varying luminance, separated by smooth surfaces, which are disposed along the tire's circumferential and radial directions, enhancing the decorative width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smooth surface is provided on the tire side face, then the surface is simple and easy to manufacture, but the decorative expression width is limited
Solution Approach 1:
The decorative section is segmented into multiple large pattern areas separated by smooth surfaces. Each large pattern area is further divided into first and second pattern areas with different luminance characteristics. This segmentation allows the tire to display complex decorative patterns while maintaining manufacturing simplicity through modular design.
Solution Approach 2:
Different regions of the tire surface are given different qualities: some areas have recesses and protrusions forming pattern areas with specific luminance characteristics, while other areas remain smooth. The first pattern areas have lower luminance and the second pattern areas have higher luminance, creating visual contrast and broadening decorative expression without complicating the entire surface.
2Adaptability or versatility
If multiple large pattern areas with varying luminance are provided on the tire outside surface, then the width of expression in decorative sections is broadened, but the structural complexity increases
Solution Approach 1:
The complex decorative structure is segmented into repeating units of large pattern areas separated by smooth surfaces. Each unit contains first and second pattern areas that can be molded as standardized modules, reducing overall structural complexity while maintaining broad decorative expression across the tire surface.

AI summary
A tire including plural large pattern areas disposed along a tire circumferential direction on a tire side section, each formed by recesses and protrusions, and partitioned by spaces that are smooth surfaces. The large pattern areas are each configured including a first pattern area and a second pattern area that is disposed adjacent to the first pattern area and that has a higher luminance than the first pattern area.
