Composite Filter Cartridge with Unified End Inlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional composite filter cartridges have a single water inlet, requiring multiple cartridges for filtering multiple water sources and leading to complex water piping arrangements due to separate inlets and outlets at different ends.
Innovation Solution
A composite filter cartridge design with two filter devices, each with independent housing and water channels, allowing for multiple water sources to be filtered with simplified piping by arranging all inlets and outlets at one end, enabling easy assembly and connection to different water piping systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional composite filter cartridge has a single water inlet and separate inlets/outlets at different ends, then the filtering function is provided, but the water piping becomes complex and confusing
Solution Approach 1:
The patent merges multiple water inlets and outlets into a single end of the filter cartridge body. Specifically, the first water inlet and first water outlet are arranged at one end, while the second water inlet and second water outlet are arranged at the same end, eliminating the need for complex piping arrangements where inlets and outlets would be distributed at different ends.
Solution Approach 2:
The patent segments the filter cartridge into multiple filter devices (first filter device and second filter device), each with independent housings and water channels. This segmentation allows each filter device to have independent inlets and outlets arranged at the same end, simplifying the overall piping configuration while maintaining multiple filtering functions.
2Adaptability or versatility
If several composite filter cartridges are used to filter multiple water sources, then multiple filtering functions are achieved, but the installation becomes complicated and space-consuming
Solution Approach 1:
The patent combines multiple filter devices with different filtering functions into a single composite filter cartridge body. The first filter device and second filter device are arranged within the same housing, allowing multiple water sources to be filtered simultaneously in one unit, eliminating the need to install and connect multiple separate filter cartridges.
Solution Approach 2:
The composite filter cartridge is designed with multi-functionality, incorporating both a first filter device and a second filter device that can handle different water sources. This universal design allows a single cartridge to perform multiple filtering functions, making it adaptable to various water filtration needs without requiring separate specialized cartridges.
3Device complexity
If water inlet and outlet are arranged at different ends of the cartridge, then the structure is simple, but the piping arrangement becomes complex
Solution Approach 1:
The patent employs asymmetric arrangement of inlets and outlets within the same end. Specifically, the first water inlet and first water outlet are positioned at one end, while the second water inlet and second water outlet are also positioned at the same end, creating an asymmetric distribution that simplifies piping by concentrating all connection points in one location rather than distributing them symmetrically across opposite ends.
