Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water filtration systems either rely on a single-stage filter membrane, resulting in unsatisfactory filtration, or use complex multi-stage cartridges that generate waste water and have intricate conduit structures, making them inefficient and unhealthy for consumption.
Innovation Solution
A compact water filtration system with a filter cartridge assembly that includes pre-filter, fine filter, and post-filter cartridges, along with optimized conduits and valves, allowing for separate output of purified and pure water, reducing waste and energy consumption by integrating a booster pump and check valves for efficient pressure control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a multi-stage filter cartridge is used to improve filtration effect, then the filtration precision is improved, but the device complexity increases due to complex conduits and many ports
Solution Approach 1:
The filter system is divided into multiple independent filter cartridges (first filter cartridge, second filter cartridge, third filter cartridge) with distinct functions. Each cartridge handles a specific filtration stage, allowing the complex filtration process to be broken down into manageable segments. This segmentation enables simplified conduit connections while maintaining high filtration precision through the coordinated operation of multiple specialized filters.
2Manufacturing precision
If a multi-stage filter cartridge is used to improve filtration effect, then the filtration precision is improved, but the volume of the device increases
Solution Approach 1:
The filter cartridges are designed to be nested or closely integrated within a compact housing structure. The first filter cartridge is positioned to receive water from the water inlet, with the second filter cartridge arranged adjacent to it, and the third filter cartridge connected in sequence. This nested arrangement minimizes the overall device volume while maintaining the multi-stage filtration capability, as each filter cartridge utilizes the space efficiently without requiring excessive clearance or separate mounting structures.
3Manufacturing precision
If a multi-stage filter cartridge is used to improve filtration effect, then the filtration precision is improved, but waste water is generated requiring separate waste water port and conduit
Solution Approach 1:
The waste water discharge function is merged with the existing purified water conduit structure. The third filter cartridge is connected to the second filter cartridge through the purified water conduit, and the waste water port is integrated into this existing conduit path. This merging eliminates the need for a completely separate waste water conduit system, reducing the number of ports and simplifying the overall conduit structure while still enabling effective waste water removal from the multi-stage filtration process.
