Dual-Source Inflation Assembly for Faster Air Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflation devices require extended time to inflate objects as they rely solely on compressed air, which is costly, and lack efficient mechanisms to utilize ambient air effectively.
Innovation Solution
The inflation device incorporates multiple air sources, including an inlet for compressed air and additional inlets for ambient air, utilizing a regulating device with a chamber and valves that open and close based on air pressure to efficiently draw in and direct air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only compressed air is used for inflation, then the inflation device can operate with a single air source, but the inflation time is extended and costs increase
Solution Approach 1:
The patent combines multiple air sources (compressed air inlet and ambient air inlet) into a single inflation system. The regulating device integrates both compressed air flow and ambient air flow through a common chamber and outlet, allowing simultaneous contribution to inflation. This merging of air sources increases the total air flow rate to the balloon, thereby reducing inflation time and improving productivity.
2Loss of time
If multiple air sources are used, then inflation time is reduced, but the device complexity increases
Solution Approach 1:
The regulating device serves multiple functions within a single component structure. It simultaneously controls compressed air flow from the first inlet, draws in ambient air through the second inlet, mixes the air streams in the chamber, and directs the combined flow to the outlet. This multi-functionality reduces the need for separate control mechanisms for each air source, thereby limiting the increase in device complexity while achieving reduced inflation time.
Solution Approach 2:
The regulating device utilizes the pressure differential between compressed air and ambient air to automatically regulate flow without requiring additional active control components. The compressed air pressure naturally drives the regulation mechanism, causing the second inlet to open when needed and close when sufficient pressure is achieved. This self-regulating behavior reduces complexity by eliminating the need for external sensors, actuators, or control systems.

AI summary
An inflation device that draws air in from two sources, such as air compressor and ambient air, can inflate an object (e.g., air bag). When a valve is opened, airflow from the air compressor is provided from the inflation device to the object. The airflow may cause airflow from an additional source (e.g., ambient air) into the inflation device. Additionally, a button used to control the valve is also used to initiate power to an assembly that includes pressure sensor (used to measure pressure of the airflow) and a display (used to present the current pressure as measured by the pressure sensor). The inflation device can automatically power down at a predetermined time after the button is released.
