Solution Overview

Problem

Current tire sidewall hatching technologies are limited in achieving three-dimensional designs due to the risk of uneven rubber distribution, which disrupts tire uniformity, and fail to effectively individualize tire designs while maintaining regulatory compliance.

Innovation Solution

The method involves deflecting the basic hatching alignment to simulate three-dimensional shapes by varying the angle and orientation of elevations, creating hatching areas that mimic three-dimensional bodies without actual deformation, allowing for individualized and complex designs while maintaining a uniform tire surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If three-dimensional designs are implemented on tire sidewalls by actually deforming the surface, then individualization and visual contrast are improved, but rubber distribution becomes uneven and tire uniformity is disrupted

Engineering Contradiction:
Improvethree-dimensional design effectVSAvoidrubber distribution uniformity
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The patent creates a copy or simulation of three-dimensional effects through hatching patterns rather than actual surface deformation. The deflected elevations mimic the appearance of three-dimensional shapes by creating visual contrast and shadow effects, achieving the desired aesthetic without physically altering the tire surface geometry.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces mechanical surface deformation with a graphical/optical simulation approach. Instead of physically shaping the rubber to create three-dimensional forms (mechanical system), the invention uses deflected hatching patterns that create the visual illusion of three-dimensionality through light and shadow effects.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If basic hatching patterns are used on tire sidewalls, then manufacturing simplicity is maintained, but design individualization and visual contrast are limited

Engineering Contradiction:
Improvehatching pattern productionVSAvoiddesign individualization
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by deflecting elevations in specific local areas to create distinct hatching patterns. Different sections of the sidewall can have different deflection patterns, allowing for individualized design elements while maintaining the overall simplicity of the manufacturing process. Each local area can be customized without complicating the global manufacturing approach.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent achieves design versatility by changing parameters of the hatching pattern, specifically the deflection angles and orientations of elevations. By varying these parameters in different regions, the invention creates diverse design effects from a single manufacturing process, enabling individualization without requiring fundamentally different production methods.

Inventive Principle:
Principle #35Parameter changes

3Illumination intensity

If elevations are deflected at large angles to create hatching areas, then visual contrast and design visibility are improved, but the complexity of the hatching pattern increases

Engineering Contradiction:
Improvevisual contrastVSAvoidhatching pattern complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent segments the sidewall surface into distinct hatching areas by deflecting elevations in specific zones. This segmentation creates clear visual separation and contrast between different design elements. The deflected elevations form discrete hatching regions that are visually distinct from adjacent areas, enhancing design visibility while maintaining manageable pattern complexity through organized segmentation.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a vehicle tire with a decorative sidewall hatching consisting of a plurality of adjacent raised areas (5, 5', 5'', 5''') which form a base hatching (6, 6', 6'', 6'''). Sections (5a, 5'a, 5"a, 5'''a) deflected from the base hatching (6, 6', 6", 6''') at uniformly large angles from elevations (5, 5'a, 5", 5'''a) form at least one locally bounded hatching area (7a, 8a, 9a, 9c, 11a, 11b), wherein the deflected sections (5a, 5'a, 5"a, 5'''a) transition into at least one further hatching area (7b, 7c, 8b, 8c, 9b, 9d, 11c, 11d) by being deflected again at uniformly large angles, so that the elevations are present in all hatching areas (7a, 7b, 7c, 8a, 8b, 8c, 9a, 9b, 9c, 9d, 11a, 11b, 11c, 11d) sections (5a, 5b, 5c, 5'a, 5'b, 5'c, 5 "a to 5"d, 5'''a ,to 5'''d) in the course of elevations (5, 5', 5", 5''') from the base hatching (6, 6', 6'', 6''').
