Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire designs fail to effectively enhance tread rigidity, increase high-speed stability, and reduce tread noise simultaneously.
Innovation Solution
The tire incorporates tread pattern structures with stepped blocks that suppress deformation under centrifugal forces and reduce ground impact vibrations, featuring grooves for soil embedding and a tapered design to concentrate forces for improved rigidity and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional tread pattern blocks are used, then traction is maintained, but tread rigidity and high-speed stability are insufficient
Solution Approach 1:
The tread pattern block is segmented into multiple levels by introducing stepped blocks with different heights. The tread pattern block is divided into a first stepped block and a second stepped block, creating a multi-level structure that enhances rigidity while maintaining functional performance.
Solution Approach 2:
The invention adds vertical dimensionality to the tread pattern by creating stepped blocks at different heights. This multi-level vertical structure transforms the conventional single-plane tread block into a three-dimensional configuration, improving rigidity and high-speed stability.
2Object-generated harmful factors
If tread pattern blocks are designed for traction, then braking stability is improved, but tread noise increases
Solution Approach 1:
The tread pattern block is divided into multiple stepped blocks of different heights, creating a segmented structure that reduces noise while maintaining braking stability through the distributed contact points of different level blocks.

Function Achieved in This Case
The tire achieves enhanced tread rigidity, high-speed stability, and reduced noise through the use of stepped blocks and grooves, demonstrating improved performance in both on-road and off-road conditions.
Implementation Method 1
the deformation of the tread surface under the influence of high centrifugal forces can be effectively suppressed
Implementation Method 2
the vibration generated by the impact of the tread surface with the ground can be also suppressed to achieve the effect of reducing tread noise

AI summary
A tire (10) includes a tire body (20) and a plurality of tread pattern structures (30) formed at a center of a tread surface (22) of the tire body (20) and arranged along a rotational direction (D) of the tire (10). The tread pattern structures (30) each have a tread pattern block (31) provided with a front end surface (312) facing towards the rotational direction (D) of the tire (10) and a rear end surface (314) facing away from the rotational direction (D) of the tire (10), and at least one stepped block (33, 34) connected with the rear end surface (314) of the tread pattern block (31) and having a height (H1, H2) lower than a height (H3) of the tread pattern block (31). As such, the tire (10) of the present invention can achieve effects of enhancing tread rigidity, increasing high-speed stability, and reducing tread noise.
