Tilted Piston Air Compressor Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors with pistons parallel to the cylinder housing axis are inefficient in compressing air due to the piston's tilt during the pumping stroke, leading to suboptimal compressing or pumping effect.
Innovation Solution
The air compressor design features a piston tilted relative to both the longitudinal and lateral axes of the piston rod, with a non-zero angle between 0 and 45 degrees, allowing the piston to be perpendicular to the cylinder housing's inner surface during the pumping stroke, enhancing air compression efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the piston is kept parallel to the lateral axis of the piston rod, then the structure is simple, but the piston becomes tilted during the pumping stroke and cannot effectively compress air
Solution Approach 1:
The piston is designed with an asymmetric tilt angle (0° < θ ≤ 45°) relative to the piston rod's lateral axis, creating an optimized geometric relationship that maintains effective compression throughout the pumping stroke while preserving structural simplicity
2Productivity
If the piston is tilted relative to the cylinder housing during pumping stroke, then air compression effectiveness is improved, but the piston structure becomes more complex
Solution Approach 1:
The piston's tilt angle θ is optimized within a specific range (0° < θ ≤ 45°) to achieve the best compression effectiveness. This parameter optimization allows the piston to maintain an optimal orientation during the pumping stroke without requiring complex mechanical adjustment mechanisms

AI summary
An air compressor includes a cylinder housing having an outlet tube and an inner peripheral surface, a piston slidably received in the cylinder housing and having a piston rod, the piston is tilted relative to a longitudinal L or lateral axis T of the piston rod, and a motor is coupled to the piston for moving the piston relative to the cylinder housing in a reciprocating action in order to generate pressurized air. The piston rod is tilted relative to the longitudinal axis Z of the cylinder housing, and the piston is arranged to be perpendicular to the longitudinal axis Z and the inner peripheral surface of the cylinder housing when the piston is moved toward the outlet tube in a pumping stroke for effectively compressing and pumping the air in the cylinder housing.
