Tire Sidewall Patterned Protrusions for Broader Decorative Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire designs with fine protrusions on the outer surface have a limited range of expression for decorative parts, as they primarily rely on brightness differences to create visual contrast, restricting the aesthetic variability.
Innovation Solution
A tire design featuring a combination of first and second patterned regions with specific protrusion heights and intervals, where the first patterned region has protrusions with extensions extending in multiple directions, and the second patterned region has closer intervals, allowing for varied brightness levels and angles, thereby broadening the range of expression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If protrusions are formed with larger intervals to reduce light reflection, then brightness is reduced, but the range of expression for decorative parts becomes limited
Solution Approach 1:
The decorative part is segmented into multiple patterned regions (first patterned region with larger intervals and second patterned region with smaller intervals), allowing different brightness levels and expressions within the same decorative part, thus resolving the contradiction between reducing brightness and maintaining versatility
Solution Approach 2:
Different regions of the decorative part are given different local qualities through varying protrusion intervals - the first patterned region has larger intervals for lower brightness while the second patterned region has smaller intervals for higher brightness, enabling diverse expressive ranges
2Illumination intensity
If protrusions are formed with smaller intervals to increase light reflection, then brightness increases, but the decorative expression becomes monotonous
Solution Approach 1:
The decorative part is divided into multiple patterned regions with different protrusion intervals, allowing simultaneous presence of both high brightness (second patterned region) and low brightness (first patterned region) areas, thus preventing monotony while maintaining brightness control
Solution Approach 2:
The first protrusions are designed with asymmetric extensions in multiple directions, creating varied light reflection patterns that enhance decorative expression beyond simple brightness control
3Object-affected harmful factors
If protrusions have extensions extending in multiple directions, then light concentration is prevented, but manufacturing complexity increases
Solution Approach 1:
The extensions of the first protrusions are designed with specific local qualities - extending in multiple directions from the base point - which effectively prevents light concentration while the overall structure remains manufacturable through standard molding processes
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 tire design achieves a broader range of expression for decorative parts by creating distinct brightness levels and angles, preventing light concentration and enhancing durability through the unique arrangement of protrusions, resulting in a more dynamic and durable appearance.
Implementation Method 1
a light incident on the first patterned region is attenuated while being repeatedly reflected by opposing side surfaces of the first protrusions
Implementation Method 2
the first protrusions each include extensions that extend from a base point in plural directions when viewed from a direction perpendicular to the base surface. This allows a light to be reflected at different angles by the side surfaces of the first protrusions
