Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum pumps are unable to change the direction of their intake ports or adjust their housing length, making them inflexible for different applications and requiring complex mounting arrangements, which complicates assembly and disassembly.
Innovation Solution
A vacuum pump design featuring a hollow housing with rotatable parts and stopping members to change the direction of the intake port, along with an ejector part and pressing means for easy assembly and disassembly, allowing for adjustable housing length and port direction changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vacuum pump uses a fixed housing structure with fixed ports, then the manufacturing and assembly are simpler, but the adaptability to different applications and locations is reduced
Solution Approach 1:
The housing is divided into multiple separable parts (first housing part and second housing part) that can be assembled and disassembled independently. The intake port is configured on one of these parts, allowing the port direction to be changed by reassembling the housing parts in different orientations, thereby achieving adaptability without requiring a completely complex redesign of the entire housing structure.
Solution Approach 2:
The housing structure transitions from a completely fixed configuration to a dynamically reconfigurable one. The intake port's direction becomes adjustable through the assembly and disassembly of housing parts, enabling the vacuum pump to adapt to different application requirements and locations while maintaining structural integrity during operation.
2Adaptability or versatility
If the vacuum pump uses a complex mounting arrangement to achieve port direction change, then the adaptability is improved, but the assembly and disassembly difficulty increases and productivity decreases
Solution Approach 1:
By segmenting the housing into separable parts with standardized interfaces, the invention enables easy assembly and disassembly without requiring complex mounting arrangements. The intake port direction can be adjusted by simply reassembling the housing parts in different configurations, significantly improving manufacturability and productivity while maintaining adaptability.
3Adaptability or versatility
If the vacuum pump housing length is fixed, then the manufacturing is simpler, but the ability to adjust according to different cartridges and applications is lost
Solution Approach 1:
The housing is segmented into multiple parts that can be assembled in different combinations, allowing the overall housing length to be adjusted according to different cartridges and application requirements. This modular approach enables length customization without requiring a completely complex modular system, as the segmented parts can be straightforwardly assembled in series.
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
Enables flexible direction adjustment of the intake port without additional tools, simplifies assembly and disassembly, and allows for selection of housing size based on the embedded ejector part, improving usability and productivity.
Implementation Method 1
The compressed air is supplied to the inlet port 3, passes through the ejector 6 at a high speed, and then is discharged through the exhaust port 4 to the outside. Here, the air inside the suction cup 7 is induced inside the ejector 6, and is discharged along with the compressed air. In the exhaust process described above, vacuum and negative pressure are generated in the inner space of the suction cup 7

AI summary
The present invention relates to a vacuum pump and, more specifically, to a vacuum pump that is designed to change the direction of an intake port formed on a side wall of a housing, according to necessity. The vacuum pump includes: a housing; an ejector part embedded in the housing; and a pressing means provided on the outside of the housing. Particularly, the housing includes two or more parts, including a main part that has the intake port, which are disposed in a line, wherein a stopping member is formed along a contact surface there between. This structure enables the main part to rotate, and thus the direction of the intake port can be changed.
