Compact Pond Water Purifier with Integrated Filtration and UVC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purification devices for ponds require additional external filter units and pumps, leading to inefficiencies and increased effort for thorough water cleaning, and are not designed for easy installation near bodies of water.
Innovation Solution
A compact water purification device with a housing containing a skimmer, coarse dirt separator, pump, fine filter, and UVC filter, where the fine filter is positioned downstream of the coarse dirt separator and the UVC filter is separate from the pump, eliminating the need for external units and minimizing friction and pressure losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If water is routed through additional external filter units and pumps, then water cleaning thoroughness is improved, but device complexity and installation effort increase
Solution Approach 1:
The patent combines multiple filtering stages (coarse dirt separator, fine filter, UVC filter) and the pump into a single integrated housing unit. This merging eliminates the need for separate external filter units and reduces installation complexity while maintaining thorough water cleaning through sequential filtration stages within the compact device.
Solution Approach 2:
The single housing unit performs multiple functions: coarse filtration, fine filtration, UV disinfection, and water circulation pumping. This multi-functional design replaces what would traditionally require separate dedicated units for each function, simplifying the overall system while achieving comprehensive water purification.
2Manufacturing precision
If additional external filter units are arranged near the pond, then water purification capability is improved, but ease of installation deteriorates
Solution Approach 1:
By integrating all filtration and pumping components into one self-contained housing unit, the patent eliminates the need to install and connect multiple separate units near the pond. The unified design allows for simpler installation with fewer connection points and reduced piping requirements, directly improving ease of installation while maintaining high water purification capability.
3Manufacturing precision
If water is pushed through fine filter positioned after pump, then filtration effectiveness is improved, but energy consumption increases
Solution Approach 1:
The coarse dirt separator is positioned before the pump to perform preliminary filtration of large particles. This preliminary action removes debris that would otherwise clog or restrict flow through the fine filter, reducing the pressure differential across the fine filter and thereby lowering the energy required by the pump to maintain adequate flow rates while preserving filtration effectiveness.
4Speed
If pump and fine filter are arranged in sequence, then water flow control is improved, but friction losses increase
Solution Approach 1:
The patent arranges the pump, fine filter, and UVC filter in a compact three-dimensional configuration within the housing, optimizing spatial relationships to minimize flow path length and reduce the number of bends and connections. This spatial optimization reduces friction losses while maintaining effective water flow control through the sequential filtration stages.

AI summary
A water purification device for ponds or similar bodies of water has a housing (1) with an inlet opening (2) located on the water side, which can be at least partially closed by means of a movable closing element (3). It also includes a coarse dirt separator (8) and a pump (17) that transports the water towards an outlet opening (19) of the housing (1), both of which are arranged inside the housing (1). According to the invention, the water purification device has a fine filter (12) located downstream of the coarse dirt separator (8), which is also located inside the housing (1), preferably upstream of the pump (17). The water purification device can also include a blast filter device (UVC), which, together with the pump (17), is arranged in a section (16) of the housing (1) that is spatially separated from the coarse dirt separator (8) and the fine filter (12).
