Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple nozzles are assembled in parallel with separate valve elements between each nozzle, then vacuum generation capability is improved, but assembly complexity increases and productivity decreases
Solution Approach 1:
The patent combines multiple valve elements into a single integrated valve structure that controls multiple nozzles simultaneously. Instead of having separate valve elements between each nozzle as in conventional designs, this invention uses one unified valve assembly, reducing the number of components and simplifying the assembly process while maintaining the ability to control multiple nozzles for effective vacuum generation
2Adaptability or versatility
If each nozzle is assembled using a separate cylindrical member, then nozzle functionality is achieved, but the number of components increases making production and assembly more cumbersome
Solution Approach 1:
The patent divides the nozzle system into modular sections where nozzles are arranged in parallel rows on opposite sides of the ejector body. Each nozzle can be independently positioned and adjusted, maintaining functional versatility while allowing for simplified assembly through the modular layout and reduced component count compared to separate cylindrical members for each nozzle
3Ease of manufacture
If conventional assembly methods are used, then component manufacturing is simple, but structural stability decreases allowing parts to separate or rotate during installation and use
Solution Approach 1:
The patent features a valve assembly that is nested within the ejector body structure, with the valve housing positioned inside the main body and the valve element moving within a designated chamber. This nested arrangement provides structural stability by containing all moving parts within the rigid body framework, preventing separation and rotation during installation and use while maintaining manufacturing simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The improved design facilitates easy assembly, enhances stability, and minimizes vacuum leakage, maintaining effective vacuum performance for efficient object gripping and transport.
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
a C-shaped clip fitted into an outer circumferential surface of the inlet pipe of the body and having one end that presses the other end of the casing supported by a hook protrusion of the outlet pipe toward the inlet pipe

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.
