Solution Overview
Problem
Existing differential pressure type quick pressurization devices face difficulties in assembling due to the need for welding in a limited space, making the process complex and challenging.
Innovation Solution
The design incorporates a differential pressure type inflating device with screwing structures for the gas container, relief valve, gas nozzle, relief pipe, and pipe joint, allowing for easy assembly by connecting these components using screwing mechanisms instead of welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding is used to connect the fast releasing valve, gas input pipe, and pipeline, then the connections are strong and reliable, but the assembling process becomes difficult due to limited space
Solution Approach 1:
The patent replaces the welding process (thermal/chemical joining) with screw threading (mechanical joining). The gas container, fast releasing valve, and pipeline are all equipped with screw threads that allow for easy mechanical assembly and disassembly, eliminating the need for welding operations in the limited space while maintaining connection reliability through threaded fastening.
2Strength
If multiple components are connected via welding in a limited space, then the structural integrity is maintained, but the welding and assembling process becomes complex and difficult
Solution Approach 1:
The patent divides the system into modular components (gas container, fast releasing valve, pipeline, decompression control valve) that can be independently manufactured and then easily assembled through screw threading. This segmentation allows each component to be optimized separately and simplifies the overall assembly process, reducing complexity while maintaining structural integrity through standardized threaded connections.

Function Achieved in This Case
This approach simplifies the assembly process, making it more manageable and reducing the complexity associated with welding in confined spaces, while maintaining the functionality of rapid tire inflation.
Implementation Method 1
a resilient member connected between the valve body and the piston unit. The piston unit is pushed by the resilient member to sealingly close the vent holes
Implementation Method 2
When external high pressure gas enters the gas container and renders the gas pressures in the gas container and the relief pipe reaching a balance condition, the switch valve is able to be pressed to generate a pressure drop in the relief pipe that triggers the relief valve to actuate and discharge high pressure gas

AI summary
A differential pressure type inflating device, adapted for fast inflating the devices that need inflating, comprises a gas container, a relief valve, a gas nozzle, a pipe joint, a switch valve, and a relief pipe. When external high pressure gas enters the gas container and renders the gas pressures in the gas container and the relief pipe reaching a balance condition, the switch valve can be pressed to generate pressure drop in the relief pipe, which launches the relief valve and discharges the high pressure gas in the gas container from the gas nozzle. In this design, the gas container, relief valve, gas nozzle, relief pipe, and pipe joint are connected with screwing structures, so as to achieve the function of easy assembling.
