Multi-Height Tread Blocks for Tire Steering Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tires optimized for rough terrain lack sufficient steering stability, particularly in diverse terrains, despite existing designs that enhance traction and cornering force.
Innovation Solution
A tire design featuring a tread portion with multi-height blocks, including first, second, and third block portions, and corresponding block grooves, where the second and third heights are higher than the first, and strategically located to enhance edge effect and ground contact, improving traction and cornering force across various terrains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blocks are designed with multiple heights to improve edge effect and traction, then steering stability and cornering force are improved, but block structure complexity increases
Solution Approach 1:
The block is segmented into multiple height levels (first, second, and third block portions) with different heights from the groove bottom surface. This segmentation creates varying edge effects at different depths, improving traction and steering stability while maintaining a manageable structural complexity through systematic arrangement.
Solution Approach 2:
The block structure transitions from a uniform height design to a multi-dimensional height variation, where blocks have different heights (first height, second height, third height) creating a stepped configuration. This dimensional change enhances ground contact versatility and edge effect without excessive complexity.
2Area of stationary object
If multi-height blocks are used to increase ground contact area, then traction and cornering force improve, but manufacturing complexity increases
Solution Approach 1:
The block is divided into distinct segments (first, second, third block portions) with defined heights and block grooves. This segmentation allows for standardized manufacturing processes where each portion can be formed systematically, increasing ground contact area while controlling manufacturing complexity through repeatable patterns.
Solution Approach 2:
The design varies the height parameter of blocks to create multiple levels (first height, second height, third height) while maintaining consistent material composition and basic geometric forms. This parameter change approach enables increased ground contact area with relatively simple manufacturing adjustments.
3Reliability
If blocks have varying heights to enhance edge effect in mud terrain, then steering stability improves, but structural uniformity decreases
Solution Approach 1:
Different portions of the block structure have different heights (first block portion, second block portion, third block portion) tailored for specific functions. This local quality variation enhances edge effect and steering stability in mud terrain while maintaining overall structural coherence through systematic arrangement and consistent material properties.

AI summary
A tyre includes a tread portion including a groove bottom surface and a plurality of blocks protruding from the groove bottom surface. The plurality of blocks includes one or more multi-height blocks. Each multi-height block includes a first block portion having a first height from the groove bottom surface, a second block portion having a second height from the groove bottom surface, a third block portion having a third height from the groove bottom surface, and a block groove to define the first block portion, the second block portion and the third block portion. The second height is higher than the first height, and the third height is higher than the second height.
