Vehicle Tire Sidewall Hatching for Concealing Unevenness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle tire sidewall hatching designs fail to effectively conceal construction-related unevenness and constrictions, such as carcass indentations, while providing aesthetically pleasing light and shadow effects.
Innovation Solution
The design features radially extending elevations from a central area in hatching elements, forming uniformly structured n-corners or parts thereof, which create special light and shadow effects, and varying degrees of reflection to conceal unevenness, with irregular pentagons being particularly effective in producing a star-like and aesthetic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional sidewall hatching designs are used, then the sidewall has a decorative appearance, but construction-related unevenness and carcass indentations remain visible
Solution Approach 1:
The hatching elements are designed with varying elevation heights across different regions. Central elevations have different heights than outer elevations, creating zones of different reflectivity. This local variation in quality allows certain areas to reflect light differently, effectively masking underlying unevenness while maintaining decorative patterns.
Solution Approach 2:
The invention changes the parameter of elevation height within hatching elements. By varying the height of elevations (particularly making central elevations taller than outer ones), the surface creates different light reflection angles and intensities. This parameter change transforms the uniform decorative pattern into a multi-layered optical structure that conceals defects.
2Ease of manufacture
If uniform elevations are used across the entire hatching area, then the manufacturing process is simple, but light and shadow effects are insufficient to conceal unevenness
Solution Approach 1:
Each hatching element is segmented into different elevation zones: central elevations and outer elevations with different heights. This segmentation creates distinct light reflection zones within each element, generating richer shadow effects that conceal unevenness while maintaining a systematic manufacturing approach.
Solution Approach 2:
The hatching elements incorporate asymmetric elevation patterns where central elevations differ in height from outer elevations. This asymmetry breaks the monotony of uniform patterns and creates dynamic light and shadow interactions that effectively mask sidewall defects.

Function Achieved in This Case
This approach effectively conceals tire sidewall bumps and unevenness, drawing attention to the radial course of elevations and creating a uniform decorative effect, while enhancing the tire's visual appeal.
Implementation Method 1
the radially extending elevations producing special light and shadow effects and different degrees of reflection resulting in unevenness in the tire sidewalls being concealed particularly well

AI summary
The invention relates to a vehicle tire with a decorative lateral wall hachure made of a plurality of linearly running elevations (4) which are formed on hachure surfaces (7) that form hachure elements (6). The hachure elements (6) are identical regular or irregular n-sided polygons, where n is four to six, and common outer element sides (6a) of the polygons directly adjoin one another. The elevations (4) in the hachure surfaces (7) of a hachure element (6) run in a radial manner from a central region (8) of the hachure element (6) to the element sides (6a). The number of the elevations (4) is the same in all of the hachure surfaces (7), and at common element sides (6a) of hachure elements (6), the elevations (4) from the corresponding hachure surfaces (7) directly abut one another.
