Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple nozzles are assembled in parallel with separate valve elements between each nozzle, then the vacuum pump can function properly, but the assembly complexity increases and productivity decreases
Solution Approach 1:
Multiple valve elements are integrated into a single valve body structure, eliminating the need for separate valve elements between each nozzle. This merging of components simplifies the assembly process while maintaining the vacuum pump's functional reliability.
Solution Approach 2:
The valve body is designed as a universal component that performs multiple functions simultaneously, serving as both the structural support and the valve mechanism for multiple nozzles, thereby reducing overall device complexity.
2Ease of manufacture
If each nozzle is assembled using a separate cylindrical member, then the nozzle structure can be manufactured independently, but the overall structure becomes unstable and parts can be arbitrarily separated or rotated
Solution Approach 1:
The separate cylindrical nozzle members are nested within a unified valve body structure, allowing independent manufacturing of nozzles while the valve body provides structural stability and prevents arbitrary separation or rotation during installation and use.
Solution Approach 2:
The nozzle assembly is segmented into independently manufacturable cylindrical members that are then integrated into the valve body, combining the benefits of independent manufacturing with overall structural stability.
3Ease of manufacture
If separate cylindrical members are used for each nozzle, then manufacturing flexibility is improved, but the number of components increases making production and assembly more cumbersome and uneconomical
Solution Approach 1:
Multiple nozzle functions are merged into a single integrated valve body structure, reducing the total number of components while maintaining manufacturing flexibility through modular design elements.
Solution Approach 2:
The valve body serves as a universal component that integrates multiple nozzle functions, reducing component count and simplifying production and assembly processes while maintaining ease of manufacture.

Function Achieved in This Case
The design enables easy assembly, maintains structural stability, and significantly reduces vacuum leakage, enhancing productivity and performance.
Implementation Method 1
the flap valve part extends from the fixing part and is configured to open and close the through-hole by an air pressure
Implementation Method 2
when the supplied compressed air passes through the ejector body at high speed and is discharged, air inside the vacuum chamber is drawn into the body through the through-hole and discharged together with the compressed air

AI summary
Provided is a vacuum ejector pump that operates through high-speed compressed air. The ejector pump includes an external ‘C’-shaped clip for securely fixing a casing assembled to a nozzle body, an internal fastening groove and protrusion to prevent arbitrary rotation of the casing relative to the body, and a guide groove and protrusion to indicate the assembly orientation of the body and the casing. Additionally, a check valve that is organically coupled to the body is further included. Accordingly, when using the vacuum ejector pump, the entire structure may be maintained in a robust and stable manner. As a result, vacuum leakage may be minimized.
