Air Pump Pressure-Valve Mechanism for Automatic Inflation Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable air pumps require human intervention to monitor and control inflation and deflation, leading to inefficiencies, potential safety hazards, and inconvenience due to exposed power lines and frequent plugging/unplugging.
Innovation Solution
An air pump with a housing, knob mechanism, inflation and deflation linkage, and air channel switching mechanism that automatically stops inflation or deflation when a set pressure value is reached, using ducts and a pressure valve to communicate with the inflatable product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If human intervention is used to monitor inflation and deflation, then control over the process is maintained, but human resources and time are wasted and errors occur
Solution Approach 1:
The air pump system monitors its own inflation and deflation status through the control module detecting pressure changes in the chamber, and automatically stops the process when the target state is reached, eliminating the need for human intervention while maintaining simple operation
Solution Approach 2:
The control module continuously detects the pressure state of the chamber and uses this feedback information to determine when to stop inflation or deflation, creating a closed-loop control system that achieves automation without complex manual monitoring mechanisms
2Ease of operation
If power line is exposed to the outside of the inflatable product, then power supply is accessible, but the appearance is affected and the power line is easy to be damaged
Solution Approach 1:
The power line is nested within the inflatable chamber structure, running through the interior space of the chamber rather than being exposed externally. This protects the power line from damage while maintaining power supply functionality, as the chamber itself serves as a protective enclosure
3Adaptability or versatility
If power line is detachably connected to the power interface, then flexibility is provided, but frequent plugging and unplugging causes inconvenience and safety accidents
Solution Approach 1:
The power line connection is merged with the chamber assembly as a single integrated unit. The chamber and power connection are treated as one component that is either fully connected or fully disconnected, eliminating the need for repeated plugging and unplugging of separate power interfaces while maintaining flexibility through complete assembly replacement
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
Enables automatic and efficient inflation and deflation processes, reducing human error, improving safety by eliminating the need for constant human intervention and minimizing power line exposure.
Implementation Method 1
When the air pressure in the duct reaches a set pressure value, the pressure valve moves and controls the knob mechanism to rotate

AI summary
An air pump with automatic stop of inflation and deflation includes a housing provided with a first air inlet/outlet and a second air inlet/outlet. The inside of the housing is provided with a knob mechanism, an inflation and deflation linkage and an air channel switching mechanism which is connected to the product to be inflated or deflated through the second air inlet/outlet. The inflation and deflation linkage controls the air channel switching mechanism to be operatively connected to the knob mechanism which controls the displacement of the air channel switching mechanism so as to be communicated with the product to achieve inflation or deflation or not to be communicated with the product to achieve automatic stop of inflation or deflation.
