Enlarged Outlet Compartment Air Compressor Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors have a reduced compartment size in their outlet receptacles, which limits the effective pumping of pressurized air and the reciprocating motion of the piston, resulting in inadequate compression and operation.
Innovation Solution
An air compressor design featuring an enlarged compartment in the outlet receptacle with a partition and a spring-biased check valve, allowing pressurized air to flow easily from the cylinder housing into the outlet receptacle while preventing backflow, and including pegs and gaps to guide the check valve, ensuring efficient air flow and piston movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the outlet receptacle compartment is made reduced or narrowed, then the structure is more compact, but the pressurized air cannot be effectively pumped and the piston cannot be effectively moved
Solution Approach 1:
The patent changes the volume parameter of the outlet receptacle compartment from a reduced size to an enlarged size that is no less than the cylinder housing chamber volume. This parameter change enables effective pumping of pressurized air and proper reciprocating motion of the piston, directly resolving the contradiction between compact structure and pumping efficiency.
2Length of stationary object
If the compartment size is reduced, then the device size is decreased, but the piston moving speed and compression effectiveness are reduced
Solution Approach 1:
The patent enlarges the compartment dimensions (length, width, height) to be no less than the chamber dimensions, which enables the piston to achieve sufficient moving speed and travel distance for effective compression. This resolves the contradiction by prioritizing functional performance over compact dimensions.
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
The design enhances the compressing effect and operation by allowing pressurized air to flow efficiently into the enlarged compartment, increasing the piston's moving speed and improving the overall air compression process.
Implementation Method 1
a spring-biased check valve disposed in the outlet receptacle and engaged with the partition for selectively blocking the air passage of the partition and for guiding the pressurized air to flow from the chamber of the cylinder housing into the compartment of the outlet receptacle

AI summary
An air compressor includes a cylinder housing (20), an outlet receptacle (40) disposed on the cylinder housing, and a partition (22) formed between the cylinder housing and the outlet receptacle and having an air passage formed in the partition, a piston slidably received in the cylinder housing and coupled to a motor for moving relative to the cylinder housing in a reciprocating action in order to generate a pressurized air, and a spring-biased check valve engaged with the partition for selectively blocking the air passage of the partition, the outlet receptacle includes an inner diameter "D2" no less than an inner diameter "D1" of the cylinder housing for allowing the pressurized air to easily flow into the outlet receptacle and for allowing the piston to be moved in a greater moving speed.
