Solution Overview
Problem
Existing filter assemblies for water purifiers, particularly POE-type systems, face challenges in ease of maintenance, separation of components, and prevention of arbitrary rolling, which complicates filter replacement and maintenance.
Innovation Solution
A filter assembly design featuring a screw-coupled filter support housing with a handle member that allows for easy separation and maintenance, incorporating anti-rolling ribs to prevent component spinning and improve filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter housing is firmly combined to withstand high water pressure, then the reliability of the water purifier is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The filter housing is divided into a body part and a lid part that can be separated from each other. The body part includes a first opening for filter insertion and a second opening for filter removal, while the lid part covers the first opening. This segmentation allows the filter to be accessed and replaced without disassembling the entire housing structure, maintaining the firm combination for reliability while enabling easy maintenance.
2Reliability
If the filter housing is firmly combined to withstand high water pressure, then the reliability of the water purifier is improved, but the ease of operation deteriorates
Solution Approach 1:
The filter element is extracted as a separate, removable component from the housing. The filter can be inserted through the second opening into the filter housing and secured without requiring disassembly of the housing itself. This extraction allows users to easily replace the filter by simply removing the lid part and pulling the filter out, maintaining the firm combination for reliability while improving ease of operation.
3Ease of manufacture
If cylindrical components are used for filter housing, then the manufacturing simplicity is improved, but the stability of the object deteriorates due to rolling
Solution Approach 1:
The lid part is designed with an asymmetric shape that includes a curved surface and a flat surface, breaking the cylindrical symmetry of the filter housing. The curved surface is configured to prevent the lid from rolling during installation or maintenance operations. This asymmetry maintains the manufacturing simplicity of cylindrical components while preventing arbitrary rolling and improving stability.
