Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuuming devices require hose adjustments and multiple hoses or ports for switching between collection and discharge modes, complicating the operation of liquid vacuuming and filtering processes.
Innovation Solution
A liquid vacuuming and filtering device with a reversible pneumatic pump and a two-way valve allows for seamless transition between collection and discharge modes using a single flexible hose, eliminating the need for hose disconnections and additional ports by utilizing a sealed container, filter, and standpipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vacuuming device uses multiple hoses or ports for switching between collection and discharge modes, then the device can perform both functions, but the operation becomes complex requiring hose adjustments and disconnections
Solution Approach 1:
The single hose is designed to serve dual functions: collecting contaminated fluid during vacuuming mode and discharging filtered fluid during discharge mode. The two-way valve integrated into the hose connection enables the hose to switch between these functions without requiring physical reconfiguration, thus achieving multi-functionality with a single component
Solution Approach 2:
The patent combines the collection and discharge pathways into a single hose system. The two-way valve merges the functionality of separate collection and discharge hoses into one unified component, eliminating the need for multiple hoses and simplifying the overall system structure while maintaining both operational modes
2Adaptability or versatility
If a vacuuming device requires hose disconnection and reconnection for mode switching, then collection and discharge can be separated, but time is lost during mode transitions
Solution Approach 1:
The two-way valve is designed to be easily adjustable between positions, allowing rapid switching between collection and discharge modes without permanent structural changes or time-consuming disconnections. The dynamic positioning of the valve enables quick mode transitions while maintaining sealed connections throughout
Solution Approach 2:
The two-way valve is pre-configured with positions for both collection and discharge modes, allowing the operator to simply shift the valve to the appropriate position for the desired mode. This preliminary setup eliminates the need for actual disconnection and reconnection actions during mode transitions, saving time
3Adaptability or versatility
If a vacuuming device uses multiple ports for collection and discharge, then fluid pathways can be separated, but the device structure becomes complex
Solution Approach 1:
The single hose with integrated two-way valve serves multiple functions: acting as both the collection hose and discharge hose. The valve itself provides multiple ports internally but presents a single external connection point, reducing overall system complexity while maintaining the ability to separate fluid pathways when needed
Solution Approach 2:
The patent merges the collection port and discharge port into a single physical location on the container, with the two-way valve managing the separation of pathways internally. This consolidation reduces the number of external ports and hose connections required, simplifying the device structure while preserving functional separation of fluid pathways
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 efficient collection and filtration of contaminated fluids, such as machine coolant, with the ability to recondition and return filtered fluid to its source without hose reconnection, facilitating easy operation and versatile applications like spill cleanup and fluid reclamation.
Implementation Method 1
the pump evacuates air from within the container to create a below-ambient pressure within the container. This partial vacuum may cause fluid to be drawn through the flexible hose
Implementation Method 2
the filter may trap and collect the particulate material that was suspended in the fluid or was taken in through the hose along with the fluid
Implementation Method 3
the reversible vacuum pump pressurizes the container interior to a pressure above ambient. The above-ambient pressure within the container may cause fluid within the container to flow through this channel and be discharged through the hose

AI summary
A liquid vacuuming and filtering device may include a container having a sealed interior, a vacuum pump connected to the interior, a two-way valve connected to the interior, a flexible hose connected to the valve, a filter positioned within the interior and connected to the valve and a standpipe positioned within the interior and connected to the valve. The pump may be adjusted to a filling configuration, in which the pump evacuates the container interior to a pressure below ambient, causing fluid to be drawn through the hose, valve, and filter, which collects suspended particulates; or to a discharge configuration, in which the pump pressurizes the interior to a pressure above ambient, wherein the valve is adjusted to allow filtered fluid within the container to flow through the standpipe, valve and out through the hose.
