Vehicle Tire Safety Unit for Anti-Slippage and Piercing Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle tire designs face issues with slippage and vulnerability to piercing due to loose engagement between inner and outer tires, which compromises driving safety.
Innovation Solution
A vehicle wheel design incorporating a safety unit sandwiched between the inflatable and grounding tires, featuring coiled lining plates that enhance engagement and provide anti-piercing protection, ensuring synchronous rotation and preventing slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the inner tire and outer tire are both made of soft rubber material to reduce wear, then the tire flexibility and comfort are improved, but the engagement between the inner and outer tires becomes loose, causing slippage
Solution Approach 1:
A safety unit is introduced as an intermediary component between the inner tire and outer tire. This safety unit includes engagement structures that mechanically couple the two tires, preventing relative rotation and slippage while allowing both tires to maintain their soft rubber material properties for flexibility and comfort.
Solution Approach 2:
The safety unit is divided into multiple segments including a first lining plate and a second lining plate that can be separately positioned between the inner and outer tires. These segmented components work together to provide distributed engagement points, enhancing the overall coupling effectiveness while maintaining tire flexibility.
2Device complexity
If the inner tire directly abuts the inner periphery of the outer tire to simplify structure, then the device complexity is reduced, but the tire becomes vulnerable to piercing by sharp articles
Solution Approach 1:
The safety unit acts as a protective intermediary layer between the inner tire and outer tire. When a sharp article pierces the outer tire, the safety unit absorbs or deflects the penetrating force, preventing direct contact with the inner tire and avoiding air leakage or bursting.
Solution Approach 2:
The safety unit is pre-installed between the inner and outer tires to provide advance protection against piercing. This cushioning layer is positioned beforehand to intercept any sharp objects that might penetrate the outer tire, preventing catastrophic failure of the inner tire.
3Adaptability or versatility
If the inner and outer tires are loosely engaged to allow independent rotation, then the tire can adapt to road conditions, but the tires rotate relative to each other causing slippage and energy loss
Solution Approach 1:
The safety unit serves as a mechanical mediator that couples the rotational motion of the inner and outer tires. It allows both tires to rotate synchronously as a unified system, preventing relative rotation and slippage while maintaining the ability to adapt to road conditions through the flexibility of the soft rubber material.

AI summary
A vehicle wheel includes a rim, an inflatable tire, a grounding tire, and a safety unit. The rim includes two tire engagement portions spaced from each other in a longitudinal direction. The inflatable tire is mounted around the rim and includes an inner annular bottom wall and two inner annular sidewalls respectively on left and right sides of the inner annular bottom wall. Each inner annular sidewall includes an inner side having a lip pressing against one of the tire engagement portions of the rim. The grounding tire is mounted around the inflatable tire and includes an outer annular bottom wall capable of rolling contact with the ground. The safety unit is sandwiched between the inflatable tire and the grounding tire to couple the inflatable tire and the grounding tire together, permitting synchronously rotation of the inflatable tire and the grounding tire while increasing the anti-slipping effect.
