Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple nozzles are arranged in series with connection parts, then vacuum pumping capability is improved, but connection parts are prone to deformation and separation due to external force and shocks
Solution Approach 1:
The patent integrates multiple nozzles and valve members into a single integrated body, eliminating separate connection parts between nozzles. The nozzles are arranged in series within the same housing structure, merging what were previously separate components into one unified unit that resists deformation and separation from external forces.
2Adaptability or versatility
If multiple separate components are used for nozzles and valve members, then functionality is improved, but assembly and manufacturing become difficult and inconvenient
Solution Approach 1:
The patent combines multiple nozzles and valve members into a single integrated body that can be manufactured as one piece. This unified structure maintains all necessary functional capabilities while dramatically simplifying manufacturing and assembly processes, eliminating the need to handle and assemble multiple separate components.
Solution Approach 2:
The integrated body serves multiple functions simultaneously - it houses multiple nozzles for vacuum pumping, contains valve members for pressure control, and provides structural support. This multi-functional design maintains versatility while reducing component count and simplifying manufacturing.
3Adaptability or versatility
If a complex structure with many parts is used, then functional capability is improved, but shock resistance and structural integrity are weakened
Solution Approach 1:
The patent consolidates multiple functional elements into a single integrated body with a unified structure. This merging of components creates a more stable and shock-resistant construction while maintaining all necessary functional capabilities through the integrated design.
4Reliability
If valve members are extended along holes from nozzle edges, then valve function is achieved, but manufacturing and mounting become very difficult
Solution Approach 1:
The patent integrates valve members directly into the integrated body structure, where they are formed as part of the same manufacturing process. This eliminates the need for separate mounting operations and makes the valve members much easier to manufacture and install while maintaining their sealing and control functions.
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 design enables convenient assembly and production, improved shock resistance, and reliable maintenance of nozzle alignment, maintaining vacuum efficiency even under external disturbances.
Implementation Method 1
a nozzle body (11) including a frame (15) and nozzles (16, 17), wherein the frame (15) includes an air inlet pipe (18), discs (19, 20), and an air outlet pipe (21), which are sequentially arranged to be spaced apart from each other
Implementation Method 2
When compressed air is discharged through the nozzles 105, 106, and 107 at high speed, air present in the vacuum chamber 104 and the external device is also discharged, so that the pressure in the vacuum chamber 104 drops
Implementation Method 3
flexible valve members (23) mounted to the spacers (22); a cylindrical casing (12) having a hole (28) formed at a position corresponding to each valve member (23)

AI summary
Disclosed herein is a vacuum ejector pump. The pump is operated by compressed air which is supplied to or discharged from the pump at high speed, thus creating negative pressure in an outer surrounding space. The ejector pump includes a frame having an air inlet pipe, a disc, and an air outlet pipe which are sequentially arranged to be spaced apart from each other. The parts are coupled into a single structure via a spacer. A nozzle is mounted to pass through the center of the disc, and a flexible valve member is mounted to the spacer. A nozzle body is accommodated in a cylindrical casing having a hole at a position corresponding to the valve member, and defines a chamber inside the spacer. A locking structure is provided on the casing and the nozzle body so as to prevent the casing, which accommodates the nozzle body, from rotating.
