Suction Device Self-Cleaning Line Design to Reduce Germ Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Suction devices often leave residual dirt in the suction line arrangement, leading to an increased buildup of germs, which existing technologies fail to effectively address.
Innovation Solution
A suction device with a discharge arrangement and a guide element that allows for fluidic connection between the discharge and suction line arrangements, enabling internal cleaning by diverting cleaning fluid from the discharge arrangement into the suction line arrangement, using clean water, steam, or a mixture of cleaning agent and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction device performs suction operations, then cleaning functionality is provided, but residual dirt remains in the suction line arrangement leading to germ buildup
Solution Approach 1:
The suction device cleans itself by using its own discharge arrangement to supply cleaning fluid through the guide element into the suction line arrangement, eliminating the need for external cleaning equipment and enabling automatic internal cleaning to prevent germ buildup
2Reliability
If a guide element is added to enable internal cleaning, then cleaning functionality is improved, but device complexity increases
Solution Approach 1:
The guide element serves multiple functions: it guides cleaning fluid from the discharge arrangement into the suction line arrangement, acts as a support element for the suction tube, and provides a mounting structure. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity
3Ease of operation
If the guide element is detachable, then ease of cleaning is improved, but connection reliability may be compromised
Solution Approach 1:
The guide element is designed as a detachable component that can be easily removed from the suction device for cleaning purposes. This extraction of the cleaning function into a separate, removable part allows thorough cleaning while maintaining connection reliability through proper reattachment procedures
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
Effectively minimizes the risk of germ buildup in the suction line by allowing for simple and efficient internal cleaning using the device's own components, ensuring a fluid-tight and secure transfer of cleaning fluid.
Implementation Method 1
a suction unit (40) that generates a suction flow and through which a suction line arrangement (88) is configured to be connected in order to be able to remove liquid by suction

AI summary
A suction device, including a suction unit, a suction line arrangement that is fluidically connected to the suction unit, a fluid supplying arrangement, a discharge arrangement for fluid, which is fluidically connected to the fluid supplying arrangement, and a guide element that is couplable to the discharge arrangement and the suction line arrangement and that guides fluid from the discharge arrangement into the suction line arrangement, for cleaning the suction line arrangement.
