Air Compressor Dual Tank Pressure Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard air compressors either require a long startup time to achieve high pressure due to large tanks, leading to undesirable wait times, or quickly deplete air pressure due to small tanks, failing to balance quick startup with extended operation.
Innovation Solution
An air compressor system with a primary and secondary tank configuration, where the air pump drives pressurized air from the primary tank to the secondary tank once a set pressure is reached, utilizing air flow control valves and a one-way check valve to maintain pressure and simulate a larger tank's airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a large pressurized air tank is used, then the reserve of high pressure air is sufficient for extended operation, but the startup time to build up working pressure becomes slow
Solution Approach 1:
The air tank system is segmented into two separate tanks: a small primary tank for quick pressurization and a large secondary tank for extended air supply. The primary tank can rapidly build up working pressure from the compressor, while the secondary tank provides sufficient reserve capacity for prolonged operation, thus resolving the contradiction between fast startup and extended duration.
Solution Approach 2:
The small primary tank is pre-filled with compressed air quickly during startup, establishing immediate working pressure availability. This preliminary action allows the system to achieve operational status rapidly, while the larger secondary tank stands ready to provide extended supply capacity once activated through the valve system.
2Loss of time
If a small pressurized air tank is used, then the startup time to build up working pressure is quick, but the reserve of high pressure air is insufficient for extended operation
Solution Approach 1:
The air storage system is divided into two functional segments: a small primary tank optimized for rapid pressurization and a large secondary tank optimized for extended air supply. This segmentation allows each tank to specialize in one aspect of the contradiction, with valves controlling air flow between them to provide both quick startup and prolonged operation capability.
3Quantity of substance
If a large pressurized air tank is used, then the reserve of air pressure is sufficient, but the compressor must run for several minutes to fill the tank
Solution Approach 1:
The air storage capacity is segmented into two tanks of different sizes. The small primary tank can be filled quickly by the compressor, providing immediate working pressure with minimal energy consumption. The large secondary tank provides the necessary air reserve capacity but is filled incrementally through the valve system, allowing the compressor to operate efficiently without continuously running at high capacity.
Solution Approach 2:
The system uses partial filling of the secondary tank through controlled valve operation. Rather than continuously filling the entire large tank capacity, the system transfers air from the primary to secondary tank as needed, using only the necessary portion of the large tank's capacity for each operational cycle, thus reducing overall compressor runtime and energy consumption.
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 quick startup and extended operation without waiting for air pressure, reducing energy consumption and extending compressor life by efficiently managing air pressure between tanks.
Implementation Method 1
A motor drives an air pump that supplies pressurized air to a primary air tank
Implementation Method 2
An air flow control valve allows pressurized air to flow from the primary tank to the secondary tank
Implementation Method 3
The second air valve that connects the primary tank to the secondary air tank is a one way check valve. This one way check valve allows pressurized air to flow from the secondary air tank back to the primary air tank when air pressure is higher in the secondary tank than the primary tank

AI summary
An air compressor includes a compressor unit having a motor, a pump operably coupled to the motor and a primary tank fluidly coupled to the pump to receive pressurized air from the pump when operated by the motor. Air compressor also includes a secondary tank connected to the first tank. The secondary tank having a different air pressure than the primary tank and the air pressure in the secondary tank being controlled by fluidly connected valves to the primary tank.
