Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vacuum pump structure design is used, then the vacuum pump can achieve vacuum function, but the size becomes large and the number of components increases
Solution Approach 1:
The motor stator and motor rotor are integrated into the same chamber as the vacuum pump components, merging the motor assembly with the vacuum pump structure. This eliminates the need for separate motor housings and reduces overall device volume while maintaining both vacuum generation and motor driving functions.
Solution Approach 2:
The main body chamber serves multiple functions simultaneously: it houses the vacuum pump rotor, contains the motor stator and rotor, provides oil storage chamber, and facilitates air intake and exhaust. This multi-functionality reduces the number of separate components and minimizes overall device size.
2Reliability
If conventional vacuum pump structure design is used, then the vacuum pump can achieve vacuum function, but the manufacturing cost increases
Solution Approach 1:
By combining the motor assembly with the vacuum pump structure in a single integrated design, the number of separate parts that need to be manufactured, assembled, and sealed is reduced. This simplifies the manufacturing process and reduces assembly costs while maintaining reliable vacuum function.
Solution Approach 2:
This principle does not apply to this patent as there are no color-related features or changes described in the technical solution.
3Reliability
If conventional vacuum pump structure design is used, then the vacuum pump can achieve vacuum function, but the space utilization becomes inefficient
Solution Approach 1:
The main body chamber is designed to perform multiple functions: housing the vacuum pump rotor, containing the motor stator and rotor, providing oil storage, and managing air flow. This multi-functional design optimizes space utilization by eliminating the need for separate housings and chambers for each function.
Solution Approach 2:
The motor rotor is positioned within the motor chamber that is itself part of the main body structure, which also contains the vacuum pump rotor and oil storage chamber. This nested arrangement allows components to be space-efficiently organized within the overall device volume.
