Composite Filter Assembly Integration for Water Purifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of water purifiers requires complex assembly processes due to the need for multiple connectors and a booster pump, leading to increased size and risk of leakage.
Innovation Solution
A composite filter assembly is integrated with a pre-filter, membrane filter, and post-filter, where the initial filtered water outlet surrounds the pressurized water inlet, allowing direct connection with the booster pump without additional connecting pipes, simplifying the assembly and reducing the number of connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If filters are connected in series with separate connectors for booster pump, then each filter can be independently maintained, but the assembly complexity increases and assembly efficiency decreases
Solution Approach 1:
The patent merges multiple separate connectors into a single integrated connector that connects the booster pump to the filter assembly. This integrated connector contains multiple connection ports that simultaneously connect to different filters, reducing the number of separate connection components and simplifying the overall assembly structure while maintaining independent filter access.
Solution Approach 2:
The integrated connector serves multiple functions simultaneously - it provides connection points for the booster pump inlet and outlet, and establishes connections to multiple different filters (pre-filter, membrane filter, post-filter) through a single component. This multi-functional design reduces assembly complexity while maintaining the ability to service individual filters.
2Stress or pressure
If multiple separate connectors are used to connect booster pump to filters, then pressure can be adjusted for each filter, but the number of connecting pipes increases and assembly efficiency decreases
Solution Approach 1:
The patent combines multiple connection functions into a single integrated connector component. This connector has multiple ports that handle both inlet and outlet connections to the booster pump and simultaneously connect to multiple filters, eliminating the need for separate connecting pipes for each filter connection and reducing the total number of components required for assembly.
3Ease of operation
If separate connectors are positioned at different locations on filter housing, then each connector can be optimally positioned, but additional connecting pipes are needed increasing assembly complexity
Solution Approach 1:
The patent integrates multiple connector functions into a single multi-port connector assembly that is positioned at one location on the filter housing. This integrated connector contains multiple ports that simultaneously provide optimal connection points for the booster pump inlet and outlet while connecting to multiple filters, eliminating the need for separate connectors positioned at different locations and the connecting pipes that would be required between them.
