Multiple Chamber Pneumatic Tire Puncture Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic tires deflate completely when punctured by sharp objects, posing safety hazards and requiring immediate repair or replacement, as they lack an internal sealing structure to maintain air pressure.
Innovation Solution
A multiple chamber pneumatic tire design with a diaphragm separating the upper and lower sections, featuring independent chambers with valves, a nail guard layer, and an interconnected barrier system that allows the tire to remain operational even after puncture, using retractable studs for improved traction and a tire pressure monitoring system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single chamber pneumatic tire is used, then the tire structure is simple, but the tire deflates completely when punctured causing safety hazards
Solution Approach 1:
The tire is divided into multiple independent chambers separated by partitions. Each chamber can maintain air pressure independently, so that a puncture in one chamber does not cause complete deflation of the tire. This segmentation allows the tire to remain partially functional even when one chamber is compromised.
Solution Approach 2:
Interconnected barriers are introduced as intermediary structures between chambers. These barriers include sealing mechanisms that can close off puncture sites, preventing air leakage from the punctured chamber while maintaining pressure in other chambers. The barriers act as mediators that isolate the harmful effect of punctures.
2Loss of time
If a punctured tire requires immediate repair or replacement, then the tire structure is simple, but it causes loss of time and safety hazards
Solution Approach 1:
The tire incorporates redundant chambers and interconnected barriers as preventive measures before punctures occur. When a puncture happens, the barriers automatically seal and the redundant chambers maintain pressure, cushioning against the harmful effect of complete deflation and allowing continued operation until safe repair is possible.
Solution Approach 2:
The system allows the punctured chamber to be effectively discarded (isolated by sealing barriers) while the remaining functional chambers continue to support vehicle operation. This enables the tire to recover functionality partially, allowing the vehicle to reach a safe location for repair without immediate tire replacement.
3Object-affected harmful factors
If compressed air is released from a punctured tire, then the puncture is relieved, but the tire becomes flat and inoperable
Solution Approach 1:
By segmenting the tire into multiple independent chambers, the release of compressed air from a punctured chamber does not affect the pressure in other chambers. The punctured chamber can vent air safely while remaining chambers maintain operational pressure, preserving tire functionality.
Solution Approach 2:
Interconnected barriers with sealing mechanisms act as intermediaries that control air release. When a puncture occurs, these barriers seal the puncture site, preventing uncontrolled air release while allowing the punctured chamber to be isolated. This maintains pressure in the overall tire system and preserves operability.

AI summary
A multiple chamber pneumatic tire having an upper section and a lower section. A diaphragm separates the upper section from the lower section. The lower section has at least two chambers. The chambers each have a chamber valve, a nail guard layer, a plurality of fibers having an end connected to an inner wall surface of a chamber, and an interconnected barrier connected to at least two portions of a chamber wall surface. The upper section of the tire has at least one linkage located within at least one tube with a primary end connected to a chamber valve of a chamber and a secondary end connected to a tire rim or to a main valve. A tire pressure monitoring system can be in communication with a chamber valve. The tire can have a ring with at least one retractable stud.
