Air Compressor Enlarged Outlet Compartment Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors have a reduced compartment size in the outlet receptacle, which limits the effective pumping of pressurized air and restricts the movement of the piston, resulting in inefficient compression and operation.
Innovation Solution
An air compressor design with an enlarged compartment in the outlet receptacle, featuring a partition with an air passage, a spring-biased check valve, and pegs with gaps to facilitate easier air flow and piston movement, ensuring the inner diameter of the compartment is larger than the cylinder housing, allowing for enhanced air flow and piston speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the compartment in the outlet receptacle is reduced or narrowed to accommodate more attachments, then the volume available for attachments increases, but the pressurized air cannot flow effectively into the compartment and the piston movement is restricted
Solution Approach 1:
Instead of reducing the compartment volume to fit more attachments, the patent inverts the approach by enlarging the compartment volume while still accommodating attachments through the side walls. This reversal resolves the contradiction by making the compartment larger for better air flow while maintaining attachment capacity through alternative spatial arrangement.
Solution Approach 2:
The patent extends the compartment in the vertical direction (upward) rather than only in horizontal dimensions, and utilizes the side walls for attachments. This dimensional change allows the compartment to have sufficient volume for effective air pumping while still providing mounting surfaces for attachments, thus resolving the space conflict.
2Ease of operation
If the compartment in the outlet receptacle is reduced or narrowed, then the structure becomes more compact, but the piston cannot move effectively and compression operation is restricted
Solution Approach 1:
Rather than narrowing the compartment shape to achieve compactness, the patent inverts the approach by designing an enlarged compartment with sufficient cross-sectional area. This allows the piston to move effectively with proper clearance while the overall compressor remains compact through optimized arrangement of other components.
Solution Approach 2:
The patent segments the functional spaces by separating the air flow path (through the enlarged compartment) from the attachment mounting areas (on the side walls). This segmentation allows the compartment to maintain an optimized shape for piston movement while still providing mounting surfaces, resolving the conflict between shape and operational ease.
3Productivity
If the compartment volume is increased to allow effective air flow, then the air pumping efficiency improves, but the outlet receptacle size increases
Solution Approach 1:
The patent extends the compartment primarily in the vertical dimension (lengthwise upward from the cylinder housing) rather than increasing all dimensions equally. This allows the compartment to achieve sufficient volume for effective air pumping while minimizing the horizontal footprint and overall receptacle area, thus resolving the contradiction between productivity and area.
Solution Approach 2:
The patent designs the compartment with a streamlined shape that tapers toward the outlet, optimizing the air flow path dynamically. This dynamic shaping allows the compartment to maintain sufficient effective volume for air pumping while reducing the overall external dimensions and receptacle area, resolving the conflict between compressing effect and outlet receptacle size.
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 effectively increases the compressing and pumping effect by allowing pressurized air to flow easily into the enlarged compartment, enabling the piston to move with greater speed and efficiency, thus improving the overall operation of the air compressor.
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
Implementation Method 2
a piston slidably received in the chamber of the cylinder housing... for moving the piston relative to the cylinder housing in a reciprocating action in order to generate a pressurized air

AI summary
An air compressor includes a cylinder housing, an outlet receptacle disposed on the cylinder housing, and a partition 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.
