Self-regulating Tire Valve Spring-Loaded Diverting Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire valve systems require frequent user intervention to maintain optimal tire pressure, as they lack self-regulation and cannot prevent over-inflation, making it cumbersome and inefficient to inflate tires to the recommended pressure.
Innovation Solution
A self-regulating tire valve with a tubular housing, a spring-loaded diverting block, and a release passageway that automatically adjusts to maintain internal tire pressure by allowing air to escape when pressure exceeds a set threshold, using a spring to bias the block into an open position and prevent over-inflation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard tire valve is used, then the tire can be inflated, but the user must frequently check pressure and manually stop pumping, which is cumbersome and time-consuming
Solution Approach 1:
The tire valve system performs self-service by automatically regulating its own pressure through the spring-loaded diverting block mechanism. When the tire reaches the predetermined pressure, the spring force pushes the diverting block to close the passageway, automatically stopping further inflation without requiring user intervention or external monitoring devices.
Solution Approach 2:
The system implements feedback control where the internal tire pressure directly acts on the diverting block to regulate the flow of air. As pressure increases, it eventually overcomes the spring force and shifts the block to close the passageway, creating a negative feedback loop that maintains pressure within the desired range and prevents over-inflation.
2Measurement precision
If the user continues pumping until the gauge reads the recommended pressure, then accurate pressure can be achieved, but the user cannot prevent over-inflation which risks tire rupture
Solution Approach 1:
The system performs preliminary action by pre-setting the spring force to correspond to the recommended tire pressure threshold. This predetermined calibration ensures that the diverting block automatically closes the air passageway before the tire can be over-inflated, preventing the harmful condition of over-pressure before it occurs rather than merely detecting it.
Solution Approach 2:
The spring-loaded diverting block mechanism applies preliminary anti-action by opposing the incoming air pressure with spring force. When the tire pressure reaches the safe threshold, the spring force becomes sufficient to shift the block and close the passageway, actively preventing further pressure increase and thus preventing the adverse effect of over-inflation and potential tire rupture.
3Loss of information
If a pressure gauge is installed permanently on the valve, then continuous pressure monitoring is possible, but the gauge only displays pressure and cannot prevent over-inflation
Solution Approach 1:
The invention merges the pressure monitoring function and the pressure regulation function into a single integrated valve mechanism. The diverting block system simultaneously senses the internal tire pressure and acts to regulate it by closing the passageway when the threshold is reached, combining what would otherwise be separate monitoring and control functions into one unified device.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and accurate inflation of tires to a specific pressure without user intervention, ensuring optimal tire condition and preventing over-inflation, thereby extending tire life and improving fuel efficiency.
Implementation Method 1
A spring is placed next to the diverting block and configured to bias the diverting block toward a closed position
Implementation Method 2
When the internal air pressure of a tire is stronger than the force of the spring, the diverting block moves into the open position

AI summary
A self-regulating tire valve for use in pneumatic tires. The self-regulating tire valve includes a tubular housing with a primary channel extending therethrough, a threaded collar on one end of the tubular housing adapted to connect to a source of pressurized air, a cavity positioned adjacent to the primary channel, and a release passageway connecting to a release outlet positioned on the exterior of the tubular housing. A diverting block is positioned with a secondary channel extending therethrough that is moveably positioned within the cavity. When the secondary channel of the diverting block is aligned with the release passageway, air can flow from a second end to a first end of the secondary channel, through the release passageway and exit at the release outlet.
