Segmented Inflation Adapter for Rapid Tire Valve Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflation adapters are time-consuming to assemble and disassemble, leading to potential tire pressure loss and driving hazards due to gas leakage during disconnection.
Innovation Solution
An inflation adapter comprising a nozzle body with a ventilation channel, sealing washer, and radially movable locking parts, where a sleeve is axially slidable to quickly secure and release the tire valve, preventing gas leakage and maintaining standard air pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional inflation adapter uses a connecting tube with internal thread to engage with the tire valve, then hermetic connection is achieved, but the assembly and disassembly process becomes time-consuming
Solution Approach 1:
The inflation adapter is divided into a seat portion and a connecting tube portion that can be separated. The connecting tube portion with the internal thread is detachably connected to the seat portion, allowing the user to quickly remove only the connecting tube portion after inflation without disassembling the entire adapter from the tire valve.
Solution Approach 2:
The connecting tube portion is extracted as a separate, detachable component from the seat portion. This allows the connecting tube to be removed independently after use, enabling quick disassembly while maintaining the hermetic connection function during inflation.
2Ease of operation
If the conventional inflation adapter is disassembled by turning the connecting tube, then connection is released, but gas leaks continuously during disassembly
Solution Approach 1:
By segmenting the adapter into detachable portions, the user can quickly remove the connecting tube portion in one action rather than slowly unscrewing it, minimizing the time the valve core is exposed and gas can leak.
Solution Approach 2:
The detachable design allows the user to quickly skip through the disassembly process by simply pulling off the connecting tube portion, reducing the duration of the vulnerable state where gas leakage occurs.
3Reliability
If the conventional inflation adapter takes long time to disassemble, then connection is maintained, but tire pressure drops below standard
Solution Approach 1:
The detachable connecting tube portion enables rapid disassembly, allowing the user to quickly remove the adapter after reaching the desired tire pressure, thereby maintaining standard pressure and preventing dangerous pressure drops.
4Reliability
If the conventional inflation adapter uses a seat that presses against the valve core, then connection is secured, but continuous gas discharge occurs during disassembly
Solution Approach 1:
By separating the connecting tube portion from the seat portion, the user can quickly detach the connecting tube after inflation, minimizing the time the seat presses against the valve core and preventing continuous gas discharge.

AI summary
An inflation adapter is used for connecting with an inflator unit and assembled to a tire valve, and the inflation adapter has a nozzle body and a sleeve sleeved on the nozzle body. The nozzle body has a ventilation channel, a sealing washer, and at least one locking part. The ventilation channel is formed axially through the nozzle body. The sealing washer is mounted in the bottom end of the ventilation channel. The at least one locking part is radially movable on the nozzle body. A user pushes the sleeve to abut against the at least one locking part to assemble the inflation adapter with the tire valve. The quickly assembling/dissembling inflation adapter saves the operation time and improves the operation convenience for driving safety.
