Tire Sidewall Pattern with Concentric Ridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire sidewall decorative patterns fail to adequately improve the outer appearance by effectively camouflaging molding defects and enhancing visibility.
Innovation Solution
A tire design featuring concentric outer and inner ridges with analogous shapes and arcs, arranged to create a stereoscopic visual effect, which connects and terminates in a manner that enhances contrast and inconspicuously masks defects, thereby improving the tire's outer appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a decorative pattern is formed on the sidewall portion to camouflage molding defects, then the outer appearance is improved, but the pattern is not sufficiently conspicuous
Solution Approach 1:
The decorative pattern is divided into multiple unit patterns that are repeatedly aligned in the tire circumferential direction. Each unit pattern contains multiple ridges that are disposed concentrically around a center point, creating a segmented structure that enhances both the camouflaging effect and visual conspicuity when viewed from different angles
Solution Approach 2:
The ridges in the unit pattern are arranged in a radial direction from the center point, creating a three-dimensional effect on the two-dimensional sidewall surface. This radial arrangement from multiple centers provides a stereoscopic visual effect that makes the pattern more conspicuous while maintaining the camouflaging function
2Ease of manufacture
If ridges are arranged concentrically around multiple points to create stereoscopic effect, then pattern conspicuity is enhanced, but the structure complexity increases
Solution Approach 1:
The unit pattern structure serves multiple functions simultaneously: it camouflages molding defects through its radial ridge arrangement, provides enhanced visual conspicuity through the stereoscopic effect of multiple concentric centers, and maintains manufacturing simplicity through repetitive alignment in the circumferential direction. This multi-functional design resolves the contradiction between complexity and conspicuity

AI summary
A tire includes a pattern portion on a surface of a sidewall portion. The pattern portion includes an outer pattern and an inner pattern. The outer pattern includes a plurality of outer ridges disposed concentrically around a first point on a tire circumferential line on an outer side in a tire radial direction and extending toward a second point, on the tire circumferential line, which is different from the first point. The inner pattern includes a plurality of inner ridges disposed concentrically around the second point on an inner side in the tire radial direction and extending toward the first point. Each of the outer ridges connects with one of the inner ridges on the tire circumferential line.
