Suction apparatus and method for operating a suction apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Suction devices often leave residues in the suction line, leading to increased nucleation and operational inefficiencies, which existing technologies fail to effectively address through internal cleaning mechanisms.
Innovation Solution
A guide element with a sealing device is used to create a fluid-tight connection between the discharge and suction line devices, allowing for internal cleaning by diverting fluid from the discharge device into the suction line, utilizing clear water, steam, or a cleaning agent mixture for effective flushing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a suction device is used for cleaning operations, then cleaning effectiveness is improved, but residues remain in the suction line leading to increased bacterial growth
Solution Approach 1:
The suction device cleans itself by using its own suction capability to draw cleaning fluid through the suction line. The control unit automatically initiates a cleaning mode where fluid is pumped through the suction line and then suctioned back, eliminating the need for external cleaning equipment while removing residues that cause bacterial growth
Solution Approach 2:
The system uses a dual-tank arrangement where a first tank stores clean water for flushing the suction line, and a second tank collects the used cleaning fluid. The control unit manages the transfer and disposal of contaminated fluid, ensuring continuous cleaning capability while preventing bacterial proliferation in the suction line
2Object-affected harmful factors
If internal cleaning mechanisms are added to the suction device, then bacterial growth is reduced, but device complexity increases
Solution Approach 1:
The pump serves multiple functions: it pumps cleaning fluid during normal operation and also pumps fluid through the suction line during cleaning mode. The control unit automatically switches between operational modes, making the existing components perform dual purposes without adding dedicated cleaning hardware
Solution Approach 2:
The cleaning function is merged with the existing suction and fluid delivery systems. The guide element, which normally directs fluid during cleaning operations, is integrated into the main body and reused during internal cleaning. The control unit combines multiple functions (fluid delivery, suction control, cleaning initiation) into a single automated system
3Productivity
If a guide element with sealing device is used for fluid-tight connection, then cleaning effectiveness is improved, but ease of operation decreases
Solution Approach 1:
The system automatically detects when the guide element is properly positioned and initiates the cleaning sequence without requiring manual intervention. The control unit monitors the positioning of the guide element and autonomously starts the pump and suction processes, eliminating the need for users to manually operate complex sealing mechanisms
