Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter mesh is used to filter impurities during water flow, then the water filtration function is improved, but the filter mesh becomes clogged frequently requiring manual cleaning
Solution Approach 1:
The patent implements a self-cleaning mechanism where the water pump reverses its rotation direction to flush accumulated impurities from the filter mesh back through the collection box. This automatic self-service function eliminates the need for frequent manual cleaning operations while maintaining reliable water filtration.
Solution Approach 2:
The system employs periodic backwashing cycles where the water pump alternates between forward rotation (filtration mode) and reverse rotation (backwashing mode). This periodic action prevents filter mesh clogging by regularly clearing accumulated impurities, thereby maintaining filtration reliability without continuous manual intervention.
2Productivity
If the water pump operates continuously in filtering mode, then the cleaning work efficiency is improved, but the filter mesh clogging prevents completion of cleaning work
Solution Approach 1:
The water pump operates in periodic cycles alternating between filtering mode (forward rotation) and backwashing mode (reverse rotation). This periodic operation maintains high cleaning productivity by preventing filter mesh clogging that would otherwise halt the debris collecting function.
Solution Approach 2:
The dual-mode operation ensures continuous useful action by maintaining filtration capability through periodic backwashing. The system avoids interruptions in cleaning work by proactively clearing the filter mesh, thereby sustaining both productivity and reliability of the debris collecting function.
3Reliability
If the filter mesh is cleaned manually frequently, then the filtration function is restored, but the user experience and cleaning efficiency are reduced
Solution Approach 1:
The automatic backwashing system performs filter mesh cleaning without user intervention. The water pump reverses rotation to flush impurities from the filter mesh, restoring filtration function automatically and eliminating time loss associated with manual cleaning operations.
Solution Approach 2:
The system implements periodic automatic backwashing cycles that restore filtration function before significant clogging occurs. This periodic self-maintenance reduces the frequency and necessity of manual cleaning, thereby recovering lost time and improving overall user experience.
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 self-cleaning function maintains cleaning efficiency by automatically or manually reversing water flow to clear impurities, reducing the need for manual cleaning and extending the apparatus' operation time.
Implementation Method 1
the water pump enables the water flow to pass through the filtering device in a direction opposite to a water flow direction in the filtering mode, to wash the filtering device

AI summary
The present disclosure provides a hand-held swimming pool cleaning apparatus and a corresponding control method. The apparatus includes a housing having at least one water suction inlet and at least one water discharge outlet, a water pump, and a detachable filtering device. The water pump operates in two selectable modes: a filtering mode and a backwashing mode. In the filtering mode, the pump directs water flow through the suction inlet, across the filtering device, and out through the discharge outlet to collect debris. In the backwashing mode, the pump reverses the flow direction, flushing water through the filtering device opposite to the filtering flow, thereby washing and unclogging the filter. This self-cleaning capability eliminates the need for manual filter washing, extends the effective service life of the filtering device, delays clogging, increases the debris collection box capacity, and prolongs continuous operation. Overall, the apparatus improves cleaning efficiency and enhances user convenience.
