Explosion-Proof Tire Safety Airbag Trigger Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current explosion-proof tires fail to provide adequate support after bursting, leading to loss of control and safety issues, especially on highways, due to insufficient bearing surface and damaged elasticity, resulting in high mortality rates.
Innovation Solution
An explosion-proof tire design incorporating a safety airbag arranged between the tire and hub, with trigger sensors and a safety switch, ensuring the airbag is triggered only upon significant pressure reduction, providing temporary support and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the tire wall is thickened to prevent bursting, then the tire strength is improved, but the tire elasticity is damaged and damping performance becomes poorer
Solution Approach 1:
The invention divides the tire structure into two functional parts: the original tire wall for normal operation and the safety airbag for emergency support. The safety airbag is segmented into multiple independent bags arranged in parallel, where each bag can independently provide support force when triggered, resolving the contradiction by separating the strength-providing function from the elasticity-providing function of the original tire wall.
Solution Approach 2:
The safety airbag is pre-installed within the tire cavity and pre-inflated to a standby state before any bursting occurs. Trigger sensors and safety switches are pre-positioned to detect pressure changes and activate the airbag system in advance, ensuring immediate support force provision without requiring post-burst inflation actions.
2Strength
If supporting devices are added to the tire, then the tire strength is improved, but the device complexity increases
Solution Approach 1:
The invention merges the safety support function with the existing tire structure by placing the safety airbag inside the tire cavity, utilizing the same space for dual purposes: normal tire operation and emergency support. The trigger sensors and switching mechanisms are integrated into the existing tire valve stem and rim structure, avoiding additional external components and reducing overall system complexity.
Solution Approach 2:
The safety airbag system is designed to automatically detect tire pressure changes through trigger sensors and autonomously activate without requiring external control systems or complex electronic interventions. The parallel circuit configuration of trigger devices provides self-diagnostic capability, ensuring system reliability while minimizing complexity.
3Reliability
If multiple trigger devices are arranged in parallel, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The invention extracts the triggering function from a single centralized control point and distributes it across multiple independent trigger sensors positioned at different locations within the tire cavity. Each trigger sensor independently monitors pressure changes and can activate the safety airbag, ensuring that failure of one trigger does not compromise overall system reliability while keeping each individual trigger device simple in design.
