Air Compressor Enlarged Compartment Reduces Piston Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors face reduced pumping efficiency due to the smaller inner diameter of the outlet receptacle compartment compared to the pumping chamber, causing increased resisting force on the piston and decreased moving speed.
Innovation Solution
An air compressor design featuring a cylinder housing with a partitioned compartment having a larger inner diameter than the pumping chamber, allowing pressurized air to flow with reduced resistance and preventing it from hindering piston movement, facilitated by a spring blade check valve and spring biasing member for controlling air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the outlet receptacle compartment has a smaller inner diameter than the pumping chamber, then the structure is more compact, but the resisting force on the piston increases and pumping efficiency decreases
Solution Approach 1:
The outlet receptacle compartment transitions from a two-dimensional cross-sectional area comparison to a three-dimensional volume configuration. By extending the compartment vertically with sufficient height, the effective storage volume is increased, allowing the piston to move with reduced resisting force while maintaining a compact horizontal footprint.
Solution Approach 2:
The invention changes the geometric parameters of the outlet receptacle compartment, specifically increasing its height dimension to compensate for a smaller base area. This parameter adjustment allows the compartment to provide adequate air storage volume without increasing the horizontal dimensions, thereby reducing piston resistance while maintaining compactness.
2Speed
If the outlet receptacle compartment has a smaller inner diameter than the pumping chamber, then the device size is reduced, but the piston moving speed decreases
Solution Approach 1:
The solution moves from optimizing the outlet receptacle compartment in two dimensions (cross-sectional area) to three dimensions by increasing height. This dimensional transition allows the compartment to provide sufficient air storage volume with a smaller base area, thereby reducing piston resistance and increasing piston moving speed while keeping the device compact horizontally.
3Productivity
If the outlet receptacle compartment has a smaller inner diameter than the pumping chamber, then the structure is more compact, but the pumping function is reduced
Solution Approach 1:
The invention resolves the contradiction between compact structure and pumping function by extending the outlet receptacle compartment vertically. This three-dimensional configuration increases the effective storage volume available for pressurized air, reducing resistance to piston movement and enhancing pumping function while maintaining a compact horizontal footprint.
Solution Approach 2:
By adjusting the height parameter of the outlet receptacle compartment, the invention optimizes the volume-to-footprint ratio. This parameter change allows the compartment to provide sufficient air storage capacity for effective pumping operation without increasing the horizontal dimensions, thereby maintaining structural compactness while improving pumping function.
