Self-Rinsing Water Filter with Hollow Cartridge and Spray Nozzles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water filters with mesh filters require manual rinsing, which can be inconvenient and may not ensure thorough cleaning of accumulated dirt.
Innovation Solution
A water filter design with a self-rinsing capability, featuring a filter housing, hollow cartridge core, and mesh filter, where a one-way pressure valve and drain tap mechanism allow for automatic rinsing of the mesh filter by reversing water flow through the filter housing, enabling air entry to facilitate easy water discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual rinsing is required, then the mesh filter can be cleaned, but user convenience deteriorates and time is lost
Solution Approach 1:
The system performs automatic rinsing of the mesh filter using the water pump to circulate water through the filter housing, eliminating the need for manual intervention. The control unit automatically initiates and manages the rinsing cycle, allowing the filter to clean itself without user involvement.
Solution Approach 2:
The rinsing function is integrated into the water filter system's operational cycles, allowing the filter to be cleaned during periods of non-use or between filtration cycles. The system proactively manages filter maintenance without requiring user initiation.
2Ease of operation
If the mesh filter is removed for rinsing, then cleaning is possible, but device complexity increases and convenience decreases
Solution Approach 1:
The mesh filter remains installed in the filter housing during automatic rinsing operations. The water pump circulates water through the housing and across the filter screen, enabling cleaning without removal. This eliminates the need for user disassembly and reassembly of filter components.
Solution Approach 2:
The water filter system is divided into functional zones: the filter housing containing the mesh filter, the water pump for fluid circulation, and the control unit for automation. This segmentation allows the rinsing function to operate independently without requiring manipulation of the entire assembly.
3Extent of automation
If automatic rinsing is implemented, then user convenience improves, but device complexity increases
Solution Approach 1:
The control unit automatically detects when rinsing is needed and initiates the rinsing cycle by activating the water pump. The system self-manages the entire rinsing process including water circulation through the filter housing and drainage, requiring no user input or intervention.
Solution Approach 2:
The water pump serves multiple functions: it powers the normal filtration operation by circulating water through the filter, and it also performs the rinsing operation by reversing or redirecting flow through the filter housing. This multi-functionality reduces the need for additional dedicated components.
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 and convenient self-rinsing of the mesh filter, ensuring thorough cleaning without manual intervention, maintaining filter effectiveness and user convenience.
Implementation Method 1
The top cover (22) also has a one-way pressure valve (223) that is designed to enable air to enter into the water filter in the self-rising mode and disable that in the working mode.
Implementation Method 2
The hollow cartridge core (3) is designed in a way that enables water to flows from the hollow tube (31) into the spray pipes (34) and then outside into the filter housing through the spray nozzles (341).
Implementation Method 3
The hollow housing (21) has a top opening (211) and a drain opening (212) preferably at its bottom part (213).

AI summary
Water filter with self-rinsing capability that includes filter housing, hollow cartridge core, and mesh filter. The filter housing includes a hollow housing with top and drain openings, a top cover with inlet and outlet ports, a one-way pressure valve, and a drain tap that includes a rod, an opening and closing knob that is connected to the rod, and an opening and closing barrier with passageway that is connected to the rod. The cartridge comprises of a tube with inlet and outlet passageways, and spray pipes with spray nozzles, and enables water to flows from the tube into the spray pipes and outside into the filter housing through the nozzles. The mesh filter has a shape of a hollow cylinder that is worn on the tube in a gap between the tube and the spray pipes.
