Air Compressor Asymmetric Piston Slant Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors experience inefficiencies due to transverse forces and sideways gaps caused by the piston's sideways sway, leading to increased friction and compromised airtightness, which affect the overall compressing performance.
Innovation Solution
The air compressor features a mounting chassis with bias-arranged coupling apertures and a piston with a slant air acting face and corresponding slant inner top wall in the cylinder, reducing sideways sway and enhancing airtightness by allowing the piston to move linearly with less resistance and maintaining contact during both forward and backward strokes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the piston has a flat air acting face and the cylinder has a flat inner top wall, then the structure is simple and easy to manufacture, but the piston experiences sideways sway causing transverse forces and compromised airtightness
Solution Approach 1:
The patent applies asymmetry by configuring both the air acting face of the piston and the inner top wall of the cylinder with slant planar surfaces instead of flat surfaces. This asymmetric configuration ensures that the piston maintains proper alignment during reciprocating motion, eliminating sideways sway and transverse forces while improving airtightness throughout the stroke cycle.
2Loss of energy
If the piston moves with sideways sway, then the mounting and operation is simpler, but friction increases and airtightness is compromised
Solution Approach 1:
The slant planar configuration of the air acting face and inner top wall creates an asymmetric geometry that guides the piston along a linear reciprocating path. This asymmetric design eliminates sideways sway during piston motion, reducing transverse forces and friction while maintaining smooth and simple piston operation throughout the stroke cycle.
3Reliability
If the air acting face and inner top wall are both configured into slant planar surfaces, then airtightness is improved throughout the stroke cycle, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs asymmetric slant planar configurations for both the air acting face and inner top wall. This design improves airtightness by ensuring continuous contact between the piston and cylinder surfaces throughout the stroke cycle. The slant surfaces are configured at corresponding angles to maintain proper alignment and sealing, with the asymmetry specifically tailored to eliminate sideways sway and ensure reliable sealing.

AI summary
An air compressor with enhanced air compressing effect comprises a mounting chassis with a coupling aperture, a piston having a piston rod with a crankpin linking bore and a piston head with an air acting face, a cylinder having an air chamber with an inner top wall, and a driving mechanism including a motor having a shaft and a rotational crank cam with an eccentric crankpin. The coupling aperture on the mounting chassis is bias disposed relative to the axial line of the cylinder. Both of the air acting face on piston head and inner top wall in cylinder are configured into corresponding slant planar surface. The eccentric crankpin on the crank cam pivotally links the crankpin linking bore on the piston rod of the piston so that rotary motion of the crank cam is converted into linear reciprocating motion. Thus, air compressing effect is substantially enhanced.
