Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If no filter device is equipped in medium-sized or small-sized inflator machines, then the device complexity is reduced and manufacturing cost is lowered, but powdery dust and moisture enter the cylinder causing wear and corrosion, thereby shortening service life
Solution Approach 1:
The filter assembly is installed at the air inlet to perform preliminary filtering of powdery dust and moisture before the air enters the drive motor and cylinder. This preliminary action prevents contaminants from causing wear and corrosion, thereby extending the service life of the inflator machine without significantly increasing overall complexity
Solution Approach 2:
The filter assembly acts as an intermediary component between the external environment and the internal components of the inflator machine. It mediates by filtering the air that enters through the air inlet, preventing harmful particles and moisture from reaching the drive motor and cylinder, thus protecting these components while maintaining relatively simple device structure
2Reliability
If no filter device is equipped in medium-sized or small-sized inflator machines, then the manufacturing cost and device complexity are reduced, but moisture and powdery dust cause corrosion and wear of the piston and cylinder wall, deteriorating the quality of the object
Solution Approach 1:
The filter assembly performs preliminary filtering of the intake air to remove powdery dust and moisture before these contaminants can enter the cylinder and cause wear or corrosion. This preliminary protective action enhances the reliability of the inflator machine by preventing damage to critical components while adding only a single filter component to the system
Solution Approach 2:
The filter assembly serves as an intermediary protective barrier that filters the air entering the drive motor and cylinder. By placing this intermediary filtering component at the air inlet, the system achieves improved reliability through prevention of contaminant-induced wear and corrosion, while maintaining relatively simple device complexity
3Reliability
If a filter assembly is connected to the bottom of the drive motor, then powdery dust and moisture are filtered off to increase service life, but the device complexity increases due to additional components and connections
Solution Approach 1:
The filter assembly is merged with the air inlet structure at the bottom of the drive motor, combining the filtering function with the existing air intake pathway. This integration approach allows the filter to be connected at the air inlet without requiring separate complex piping or mounting systems, thereby improving reliability through effective filtering while minimizing the increase in device complexity
Solution Approach 2:
The filter assembly acts as an intermediary component that integrates into the air inlet system at the bottom of the drive motor. By positioning and connecting the filter at this location, the system achieves effective filtration of powdery dust and moisture to extend service life, while the integration with the existing air inlet structure keeps the additional complexity relatively low

AI summary
A rear-side filtering and intake air compressor structure includes an air compressor, which includes at least one drive motor. The drive motor is connected, at a bottom thereof, with a closure cover. An air inlet of the air compressor is arranged on the closure cover, and is connected with a filter assembly, so that the filter assembly is connected to the drive motor of the air compressor at an outside bottom position thereof. When the air compressor is activated, external air first moves through the filter assembly to get into the interior of the drive motor. The filter assembly that is externally arranged may filter off powdery dust and moisture contained in air to effectively prevent the powdery dust and moisture entraining air from getting into the air compressor to cause damage and corrosion, thereby effectively increasing the service life of the air compressor and adaptability to various environments.
