Tire Management System Valve Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure management systems face challenges in preventing tire deflation when parked and risk dangerous tire blowouts due to the risk of sealing check valves during deflation, while also requiring costly intervention to unseal them.
Innovation Solution
The tire management system (TMS) incorporates a control valve and check valve that automatically isolates the tire from the inflation system during leaks, allows controlled deflation without triggering automatic isolation, and includes a bidirectional check valve to prevent deflation when parked, thereby preventing tire deflation and isolating the system during a blowout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a check valve is used to automatically isolate the tire from the inflation system during leaks, then tire safety is improved by preventing blowouts, but the valve may seal during controlled deflation requiring costly intervention to unseal
Solution Approach 1:
The system uses a pressure sensor to continuously monitor tire pressure and provides feedback to the control module. The control module processes this feedback and actuates the control valve accordingly to achieve controlled deflation without triggering the check valve's automatic sealing mechanism, thus avoiding costly repairs while maintaining safety.
Solution Approach 2:
A control valve is introduced as an intermediary device between the tire and the inflation system. This control valve is actuated by the control module based on pressure sensor feedback, allowing controlled deflation that prevents the check valve from sealing, thereby avoiding the need for expensive unsealing operations while maintaining tire safety.
2Stability of the object's composition
If a check valve is used to prevent tire deflation when parked, then tire pressure stability is improved, but the valve may seal during controlled deflation requiring costly intervention to unseal
Solution Approach 1:
The pressure sensor continuously monitors tire pressure and provides feedback to the control module. Based on this feedback, the control module actuates the control valve to maintain stable tire pressure when parked while preventing the check valve from sealing during controlled deflation operations, thus avoiding costly repairs.
Solution Approach 2:
The control valve serves as an intermediary that allows controlled deflation without triggering the check valve's sealing mechanism. This intermediary device enables maintenance of tire pressure stability during normal operation while preventing the check valve from sealing, avoiding expensive unsealing operations.
3Ease of operation
If conventional tire pressure management systems are used, then basic inflation control is provided, but the systems require costly intervention to unseal check valves after they seal during deflation
Solution Approach 1:
The system employs a pressure sensor to continuously monitor tire pressure and provide feedback to the control module. This feedback mechanism enables precise control of the control valve to achieve deflation without triggering the check valve's sealing action, thereby eliminating costly unsealing operations while maintaining ease of inflation control.
Solution Approach 2:
The control valve acts as an intermediary device that enables controlled deflation without causing the check valve to seal. This intermediary mechanism provides easy inflation control while preventing the need for expensive unsealing operations, addressing both ease of operation and ease of repair concerns.
4Reliability
If the check valve seals during controlled deflation to prevent leaks, then system reliability is improved, but the tire cannot be properly deflated and requires costly intervention
Solution Approach 1:
The pressure sensor provides continuous feedback to the control module during deflation operations. The control module uses this feedback to actuate the control valve in a manner that achieves proper tire deflation without triggering the check valve's sealing mechanism, thus maintaining both system reliability and deflation capability.
Solution Approach 2:
The control valve serves as an intermediary that enables controlled deflation without causing the check valve to seal. This intermediary device maintains system reliability by preventing unwanted sealing while preserving the ability to properly deflate tires, avoiding costly intervention.
