Solution Overview
Problem
Existing vacuum pumps have complex electronic and mechanical designs, leading to frequent malfunctions and difficult maintenance, and require complicated processes to quickly release vacuum states and clean filters.
Innovation Solution
A quick-release vacuum pump design featuring a cylindrical hollow area with series nozzles, a support tube with a skirt-type check valve, and a filter material that allows air to pass through for cleaning, eliminating the need for electronic control and separate release lines, enabling simple and accurate operation with quick vacuum release and natural filter cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If separate release lines with electronic control are designed to quickly release vacuum, then the vacuum release speed is improved, but the device complexity and maintenance difficulty increase
Solution Approach 1:
The patent extracts the release function from the main vacuum pump body by using a separate release line that communicates with the release space. This allows the release operation to be performed independently through a simple air supply line without requiring complex electronic control systems, thus achieving quick vacuum release while maintaining simple device structure
Solution Approach 2:
The patent uses pneumatic pressure from the air supply to directly drive the check valve open and force air into the release space, eliminating the need for electronic actuators or mechanical linkages. The pneumatic system naturally provides both the quick response and structural simplicity required
2Ease of manufacture
If filter cleaning operations are performed manually or with separate mechanisms, then the filter can be cleaned, but the operational complexity and time consumption increase
Solution Approach 1:
The patent enables the filter to clean itself by utilizing the reverse flow of air through the release line during the release operation. The air flowing from the release space through the filter naturally removes accumulated dust and debris, eliminating the need for separate manual cleaning operations or additional cleaning mechanisms
Solution Approach 2:
The filter cleaning action occurs continuously during each vacuum release cycle, rather than requiring separate maintenance operations. The same air flow that releases the vacuum also performs the cleaning function, maximizing the utility of each operational cycle
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 allows for continuous, malfunction-free operation with rapid vacuum release and natural filter cleaning, reducing complexity and maintenance needs, enhancing economic competitiveness and productivity.
Implementation Method 1
nozzles which are arrayed in series inside the casing... when compressed air is supplied through the inlet and passes through and is ejected from the nozzles at a high speed, the inner space is evacuated, thereby creating the vacuum or negative pressure
Implementation Method 2
a skirt-type check valve which is moved up and down by air pressure to open and close the upper portion of the support tube
Implementation Method 3
a filter material which is disposed between the suction port and the support tube, wherein the filter material allows discharge air that is introduced to pass through upward when the pump part operates and is cleaned by air that is supplied to the suction port below through the support tube from the pressure chamber
