Submersible Pump Filter Assembly for Aesthetic Water Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a filtration system that is easy to set up and maintain, aesthetically inconspicuous, adaptable to various locations, and cost-effective for use in both large and small water bodies, including decorative ponds and secondary treatment tanks, while effectively preventing water stagnation and contamination.
Innovation Solution
A submersible pump filter assembly with a self-supporting, perforated tubular wall portion, a base cup, and a tapered coupling, along with a secondary filter and tubular bell, which includes a motor and discharge conduit, designed to be inconspicuous and easy to maintain, using materials like PVC plastic or stainless steel, with a seal ring and suspension elements for ease of removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a filter unit is located where it can be seen, then the system is easy to access for maintenance, but it detracts from the aesthetic appeal of decorative bodies of water
Solution Approach 1:
The filter unit is enclosed in a mesh sleeve that allows it to be submerged and concealed within the water body, maintaining aesthetic appeal while enabling access for maintenance by lifting the flexible mesh enclosure
Solution Approach 2:
The pump and filter components are nested within each other, with the filter media contained inside the pump housing, creating a compact assembly that can be easily deployed and retrieved as a single unit
2Shape
If conduits are buried to locate the filter unit in an inconspicuous location, then aesthetic appeal is maintained, but setup complexity and cost increase
Solution Approach 1:
The filter unit and pump are merged into a single integrated assembly, eliminating the need for separate concealed filter chambers and complex conduit systems, allowing the entire filtration system to be simply dropped into the water body
Solution Approach 2:
The mesh sleeve serves multiple functions: it contains the filter media, allows submersion for concealment, and facilitates easy deployment and retrieval, replacing the need for buried conduits and complex installation structures
3Quantity of substance
If conventional filter systems are used in large bodies of water, then filtration capacity is sufficient, but the system becomes cumbersome and difficult to maintain
Solution Approach 1:
The filter media is segmented into multiple layers with different pore sizes, arranged concentrically from the impeller outward, providing sufficient filtration capacity for large water bodies while maintaining a compact, manageable structure that is easy to maintain
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 system effectively filters and pumps wastewater or water from various sources, maintaining water quality and aesthetics by ensuring easy setup and maintenance, while being durable and cost-effective, with the tubular bell enhancing motor longevity during prolonged use.
Implementation Method 1
A self-supporting, substantially uniformly perforated, tubular wall portion can have a lower end coupled to the base cup outer peripheral flange
Implementation Method 2
a pump having a body with at least one liquid intake port. A discharge conduit can be connected to the pump body
