Tire Decorative Projections Brightness Gradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The decorative portion of tires with projections has limited expression range due to uniform brightness reduction, restricting aesthetic appeal.
Innovation Solution
A tire design featuring a pattern region with projections of varying heights and intervals, including a gradual decrease region where projection heights decrease, and a bottom raising portion with increasing and then decreasing heights, enhancing light reflection and brightness gradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If projections are formed uniformly across the pattern region, then the decorative portion achieves a consistent low brightness appearance, but the range of expression is limited due to lack of visual variation
Solution Approach 1:
The patent applies local quality by creating regions with different projection heights within the pattern region. Specifically, it defines a first region with projections of first height and a second region with projections of second height different from the first height. This allows different parts of the decorative portion to have different brightness characteristics, thereby expanding the range of expression while maintaining overall brightness control.
Solution Approach 2:
The patent introduces height as an additional dimension for controlling brightness expression. By varying the height of projections in different regions (first height vs. second height), the invention adds a vertical dimension to the otherwise uniform pattern, enabling gradation effects and multiple brightness levels within the same decorative region.
2Adaptability or versatility
If the height of projections is varied to create brightness gradation, then the range of expression is broadened, but the structural complexity increases
Solution Approach 1:
The patent segments the pattern region into distinct regions (first region and second region) with different projection heights. This segmentation allows for controlled complexity by dividing the decorative portion into manageable zones, each with uniform projection characteristics, rather than requiring continuous variation throughout the entire pattern region.
Solution Approach 2:
The patent changes the parameter of projection height in a controlled manner by defining specific regions with different height values. Instead of continuous or random height variation, the invention uses discrete parameter changes between regions, which simplifies the manufacturing process while still achieving the desired brightness gradation effect.
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 broadens the expression range of the decorative portion by adding gradation to brightness, making the tire appear more visually appealing and reducing the risk of cracks by distributing stress evenly.
Implementation Method 1
light that enters the pattern region declines while being repeatedly reflected on side surfaces, of the projections, facing each other and is reflected to the outer side

AI summary
Provided is a tire including: a decorative portion that is formed on an outer surface of the tire and that has a base surface; and a pattern region that is provided at the decorative portion and that formed with plural projections projecting at a height of from 0.1 mm to 1.0 mm from the base surface and formed at an interval of from more than 0.1 mm to 1.0 mm, in which the pattern region is provided with a gradual decrease region in which a height of the plural projections disposed adjacent to each other gradually decreases.
