Tire Sidewall Hexagonal Ridge Pattern for Clearer Decoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic tire designs require significant time to adjust the size and curvature of serrations on the sidewall portion for different tire sizes, leading to inconspicuous unevenness and reduced decorativeness and visibility.
Innovation Solution
A decorative portion on the sidewall with hexagonal decorative elements arranged in a step-like manner along parallel reference lines, featuring ridges with different inclinations in each region, separated by boundary portions, which eliminates the need for size and curvature adjustments based on tire size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If serration size and curvature are changed according to tire size, then unevenness of sidewall portion becomes inconspicuous, but drawing time at the time of designing the tire increases
Solution Approach 1:
The patent applies a universal decorative pattern design that can be used across different tire sizes without modification. The decorative portion with specific geometric patterns (triangles, rectangles, circles) serves multiple tire sizes universally, eliminating the need to redesign serrations for each tire size while maintaining the effect of reducing sidewall unevenness visibility.
Solution Approach 2:
The patent changes the approach from modifying serration parameters (size, curvature) for each tire size to using a fixed decorative pattern with controlled parameters. The decorative portion uses standardized geometric shapes with specific dimensional relationships that remain effective across different tire sizes, transforming the problem from parameter adjustment to pattern application.
2Shape
If decorative portion is added to sidewall, then decorativeness and visibility are improved, but design complexity increases
Solution Approach 1:
The decorative portion is segmented into distinct geometric patterns (triangular patterns, rectangular patterns, circular patterns) that can be independently designed and then combined. This segmentation allows for modular design where each pattern type can be developed separately and assembled into the final decorative configuration, reducing overall design complexity.
Solution Approach 2:
The patent employs asymmetric geometric patterns within the decorative portion, particularly in the arrangement and orientation of triangles and rectangles. These asymmetric designs create visual interest and improve decorativeness while following systematic design rules that prevent excessive complexity.

AI summary
In a pneumatic tire including a decorative portion on an outer surface of a sidewall portion, the decorative portion includes a plurality of decorative elements arranged in a step-like manner along reference lines parallel to each other, each of the decorative elements forms a hexagon in which three regions forming a parallelogram are disposed sharing adjacent sides of the three regions, a plurality of ridges extending in the same direction is formed in each of the regions of each of the decorative elements, and inclination directions of the ridges are different from one another in the three regions forming each of the decorative elements.
