Innovation Solution
A detachable air filter device with a main member, conduit member, sealing piece, pressurizing piece, filter element, and cap, featuring a spiral duct design and flexible materials to ensure smooth, steady, and quiet air intake by guiding filtered air through a spiral path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple air filter is installed in the air inlet of the air compressor, then dusts and sands can be filtered, but the air filter cannot be removed or replaced and cannot be applied to another air compressor
Solution Approach 1:
The air filter device is divided into a detachable main body and a mounting bracket. The mounting bracket can be removed and transferred to different air compressors, while the main body remains with the filter element. This segmentation allows the filter to be adaptable to multiple compressors without requiring a completely new filter for each one.
Solution Approach 2:
The mounting bracket is designed with a universal interface that can be attached to various air compressor models. The bracket serves multiple functions: securing the filter to the compressor, providing a mounting structure for the filter element, and enabling easy removal and transfer to different compressors. This multi-functionality achieves versatility without proportionally increasing complexity.
2Object-affected harmful factors
If air is designed to flow in a linear manner through the air filter, then the structure is simple, but turbulent flow is easily formed causing greater noises and clogging air intake
Solution Approach 1:
The air passage within the filter body is designed with curved transitions instead of sharp angles or linear paths. The curved air passage guides air flow smoothly through the filter element, reducing turbulence and preventing eddy currents. This curvature design minimizes noise generation and prevents clogging by maintaining steady laminar flow throughout the filtration process.

Function Achieved in This Case
The device provides a versatile, efficient air filtration system that can be used with any air compressor, ensuring smooth, steady, and quiet air intake while effectively filtering impurities, thus enhancing compressor performance.
Implementation Method 1
Impurities such as dusts and particles in the air are then filtered by the filter element
Implementation Method 2
the air is guided to the first and second inlets, and then to the first and second outlets by the conduit member in a spiral manner

AI summary
The air filter device includes a main member, a conduit member, a sealing piece, a pressurizing piece, a filter element, and a cap. The conduit member, sealing piece, pressurizing piece, and filter element are sequentially stacked in the main member. The conduit member provides a spiral duct with a second inlet and a second outlet. The second inlet is conducted to an outlet opening of the pressurizing piece. The second outlet is conducted to a plug extended from a bottom side of the main member. The cap is fastened to the main member with airflow paths between the cap and main member. The main member may be joined to the inlet terminal of any air compressor. External air is drawn into the air compressor through the filter element, pressuring element, conduit member, and the plug so as to achieve smooth, steady, and quiet air intake.
