Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic tire designs lack innovative visual effects, relying on conventional patterns that fail to create new and appealing visual aesthetics.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional patterns with straight ridges or uniform three-dimensional shapes are arranged on the sidewall surface, then the manufacturing process is simple and easy to implement, but the visual effects are conventional and lack innovation
Solution Approach 1:
The patent applies asymmetry by using rhombus-shaped planes instead of conventional straight ridges or uniform three-dimensional shapes. The rhombus planes are arranged with their long diagonals extending in the tire radial direction, creating an asymmetric pattern that generates new visual effects while maintaining manufacturing feasibility through molded integration.
Solution Approach 2:
The patent transitions from two-dimensional flat patterns or simple raised ridges to three-dimensional rhombus-shaped planes with specific orientation. The planes are formed with defined thickness and angular orientation, adding dimensional complexity that creates mirror-like light reflections and enhances visual appeal without complicating the molding process.
2Illumination intensity
If rhombus-shaped planes are tightly arranged with long diagonals extending in the tire radial direction, then new visual effects and mirror-like beauty are created, but the manufacturing precision requirements increase
Solution Approach 1:
The patent merges the decorative pattern formation directly into the tire molding process. The rhombus-shaped planes are integrated into the sidewall surface during vulcanization, combining the aesthetic function with the structural formation in a single manufacturing step, thereby reducing precision requirements compared to post-manufacturing applications.
Solution Approach 2:
The rhombus-shaped planes serve multiple functions: they provide aesthetic decoration, create light reflection effects, and are formed as an integral part of the tire sidewall structure. This multi-functionality allows the same feature to satisfy both visual appeal and manufacturing efficiency requirements.
3Illumination intensity
If vertices of the rhombuses are made protruding in the normal line direction of the profile surface, then three-dimensional visual effects and light reflection are enhanced, but the surface complexity and manufacturing difficulty increase
Solution Approach 1:
The patent uses curved surfaces by forming the rhombus-shaped planes on the curved sidewall surface of the tire. The planes follow the contour of the tire, with their normal directions aligned radially, creating smooth transitions and avoiding sharp edges that would increase manufacturing complexity while maintaining three-dimensional visual effects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design generates new visual effects by creating a mirror-like beauty with alternating light reflections and increased contrast, enhancing the tire's aesthetic appeal while minimizing the appearance of internal pressure inflation streaks.
Implementation Method 1
a plurality of planes with a rhombus shape and a plurality of planes with a shape of part of a rhombus are tightly arranged in the decorative area
