Tire Shield Layer That Bends Puncturing Objects Before Air Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic tires are vulnerable to punctures from pointed objects, and existing technologies fail to effectively prevent penetration or deformation of these objects, leading to air loss in tubeless tires.
Innovation Solution
A shield system using thermoplastic or thermoset polymers with specific Shore hardness and thickness, designed to deform and bend penetrating objects, preventing them from reaching the inner tube or air in tubeless tires, and featuring an auto-adjust system for universal fitment across various tire sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a puncture-resistant layer is added to the tire, then puncture resistance is improved, but the tire structure complexity increases
Solution Approach 1:
The puncture-resistant layer is nested within the tire structure, specifically positioned between the tread and the inner tube. This nested configuration allows the protective function to be integrated into the existing tire architecture without adding external complexity, resolving the contradiction between puncture resistance and structural simplicity.
Solution Approach 2:
The invention uses a flexible puncture-resistant layer made of elastomeric material that can deform with the tire. This thin film approach provides effective puncture protection while maintaining the tire's overall flexibility and avoiding the need for rigid, complex structural modifications.
2Strength
If the puncture-resistant layer has high hardness to deform objects, then object deformation capability is improved, but the layer becomes more rigid and less flexible
Solution Approach 1:
The invention carefully selects and adjusts the hardness parameter of the puncture-resistant layer to an optimal range (Shore A 40-90). This parameter optimization allows the layer to be sufficiently hard to deform puncturing objects while remaining flexible enough to deform with the tire during normal operation, resolving the contradiction between strength and flexibility.
Solution Approach 2:
The puncture-resistant layer is made from elastomeric materials that combine the properties of flexibility and sufficient hardness. These composite material formulations enable the layer to exhibit both deformability for object penetration resistance and flexibility for tire movement accommodation.

AI summary
The disclosure pertains to the tyre industry and relates more specifically to a system of lining levels for protecting tyres that prevents pointed objects from puncturing the air chamber, or in tubeless tyres prevents pointed objects from emptying the air from the tyre, being applicable to practically all types of tyre. According to the disclosure, when the puncturing object comes into contact with the tread, it is bent and deformed, preventing it from coming into contact with the air chamber or with the air in the case of tubeless tyres. The puncturing object penetrates the rubber of the tyre, but when it reaches the lining, instead of puncturing it or deforming it, the object is bent due to a hardness ratio between the lining and the tread combined with the movement of the wheel.
