Tire Valve Assembly Movable Rod Punched Hole Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire valve assemblies are prone to blockage due to residual tire repair liquid, which reduces air intake and necessitates frequent replacement, as the liquid can stick to components and seal outlets, preventing proper inflation.
Innovation Solution
A tire valve assembly featuring a movable rod with a punched hole for tire repair liquid to flow out due to surface tension, and a design allowing the rod to be removed for maintenance to clear any remaining liquid, preventing blockage and ensuring smooth inflation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional valve structure with a single outlet is used, then the structure is simple, but the tire repair liquid blocks the outlet and prevents proper inflation
Solution Approach 1:
The valve outlet is divided into multiple outlets: a first outlet for gas passage and a second outlet for tire repair liquid drainage. This segmentation allows gas and liquid to exit through separate paths, preventing liquid blockage of the main gas outlet while maintaining a relatively simple overall valve structure.
2Reliability
If the valve components are fixed and sealed, then the sealing is good, but the residual liquid cannot be removed and seals the outlets
Solution Approach 1:
The movable rod can be displaced between a first position (sealing the second outlet during normal operation) and a second position (opening the second outlet for liquid drainage). This dynamic positioning allows the valve to switch between sealing and drainage modes, ensuring outlet patency while maintaining ease of manufacture through a simple movable component design.
3Reliability
If the valve is designed for frequent replacement, then blockage issues are avoided, but the cost and inconvenience increase
Solution Approach 1:
The valve design enables recovery and reuse of the valve assembly by providing a drainage function that removes residual liquid blocking the outlets. Instead of discarding and replacing the valve when blockage occurs, the movable rod can be actuated to drain the liquid, allowing the valve to be recovered and used again, thus reducing maintenance time and cost.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tire valve assembly effectively prevents blockage by allowing tire repair liquid to flow out through a punched hole and facilitates easy maintenance to remove residual liquid, ensuring consistent air intake and extending the valve's lifespan.

AI summary
A tire valve assembly is disclosed. The tire valve assembly includes a gas nozzle structure, a movable rod, an air pipe, an elastic close contact pad, a screw nut, an elastic O-ring and a dust cap. The tire valve assembly can use a punched hole on the end of the movable rod to receive the tire repair liquid flowing into the air pipe. Take out the movable rod during maintenance to remove the tire repair liquid in the punched hole. When the movable rod is reinstalled in the air pipe, the tire repair liquid remaining on the inner wall of the air pipe will also be squeezed out of the air pipe. With this, the tire repair liquid will no longer block the tire valve assembly.
