Vehicle Air Compressor Protection Adapter Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressor devices for tire repair can cause the liquid adhesive to suddenly shoot out due to improper handling, leading to contamination of the user or surrounding objects when the power source is activated without the flexible linking tube being connected to the tire nipple.
Innovation Solution
A vehicle-carried air compressor device with a protection adapter on the flexible linking tube, featuring a cylindrical outer sleeve, valve cock, and connecting base, which includes a spring-loaded mechanism to keep the valve seat closed until the air nipple is properly connected, preventing the adhesive from flowing out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power source is activated without the flexible linking tube being connected to the tire nipple, then the air compressor can generate pressurized air, but the liquid adhesive will suddenly shoot out from the flexible linking tube causing contamination
Solution Approach 1:
The valve cock is pre-positioned in the closed state before operation, and the protection adapter is pre-assembled on the flexible linking tube. The valve only opens after the tire nipple is properly connected to the protection adapter, ensuring the system is prepared safely before activation.
Solution Approach 2:
The protection adapter acts as an intermediary component between the flexible linking tube and the tire nipple. It includes a valve cock that mediates the flow of adhesive, allowing connection without immediate adhesive flow, and preventing contamination during improper handling.
2Object-affected harmful factors
If the valve seat is kept closed to prevent adhesive leakage, then contamination is prevented, but the adhesive cannot flow to the tire for sealing
Solution Approach 1:
The valve cock is designed as a dynamic component that transitions from closed to open state based on operational needs. The spring-loaded mechanism allows the valve to open when the tire nipple is connected and close when disconnected, dynamically controlling adhesive flow.
Solution Approach 2:
The connection between the tire nipple and protection adapter provides feedback that triggers valve opening. When the nipple is properly connected, it actuates the valve cock to open, allowing adhesive flow. When disconnected, the spring returns the valve to closed position, preventing leakage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents the liquid adhesive from shooting out during improper handling by ensuring the valve seat remains closed until the air nipple is securely engaged, maintaining containment and preventing contamination.
Implementation Method 1
A spring is mounted around the pole body and received in the axial hole of the outer sleeve between the supporting protrusion and the coupling portion. The spring biases the pole body towards the second end of the axial hole so that the blocking ring is pressed against the valve seat to close the end opening of the valve seat.

AI summary
A vehicle-carried air compressor device includes a case installed with an air compressor therein, a tire repairing container containing a liquid adhesive, and a flexible linking tube. An air inlet coupler of the tire repairing container is connected with an air outlet manifold of the air compressor. An end of the flexible linking tube is coupled to an adhesive outlet coupler of the tire repairing container, and the other end of the flexible linking tube is provided with a protection adapter for coupling to a tire nipple. Before the protection adapter is connected with the tire nipple, the other end of the flexible linking tube is closed by the protection adapter, so that the liquid adhesive in the tire repairing container will not shoot out suddenly because of improper handling.
