Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-outlet faucets with filtering devices face difficulties in filter element replacement due to limited space, affecting user convenience.
Innovation Solution
A double-outlet faucet design with a water purifier body positioned higher than the faucet body, featuring a detachable filter element and a switch valve to control tap water inlet, allowing for easy filter replacement without cutting off upstream water inflow, and a snap-fit connection for simple filter element removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the filtering device is arranged below the faucet body, then the faucet structure is compact, but the filter element replacement becomes troublesome and user experience is affected
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the water purifier body above the faucet body instead of below it. This inversion allows users to easily access and replace filter elements from above the countertop, solving the accessibility problem while maintaining a compact overall structure through vertical integration.
Solution Approach 2:
The patent transitions from a horizontal arrangement (filter below faucet) to a vertical arrangement (filter above faucet), utilizing the vertical dimension to resolve the conflict between compactness and accessibility. The water purifier body is positioned in the vertical space above the faucet, creating easy access for maintenance while preserving horizontal space.
2Ease of operation
If the filter element is detachably mounted in the filter cavity, then the filter element can be easily replaced, but the sealing and connection reliability may be affected
Solution Approach 1:
The patent segments the filter element into a modular design with a dedicated filter element head that can be detached from the water purifier body. This segmentation enables easy replacement while maintaining reliable sealing through specialized connection interfaces designed for repeated assembly and disassembly.
Solution Approach 2:
The patent introduces a connecting snap fastener as an intermediary component between the filter element head and the water purifier body. This snap fastener mechanism provides both ease of detachment for replacement and reliable sealing during operation, mediating between the conflicting requirements of replaceability and reliability.
3Ease of operation
If the water purifier body is positioned higher than the bottom of the faucet body, then the filter element replacement is convenient, but the device complexity increases
Solution Approach 1:
The patent merges the water purifier body with the faucet body through a unified structural integration. The water purifier body is positioned above the faucet body and connected through a connecting assembly, combining two functional units into a single integrated device that maintains compactness while providing accessible filter replacement.

AI summary
A double-outlet faucet, having a faucet body, a tap water outlet device and a purified water outlet device. The tap water outlet device is arranged on the faucet body. The purified water out device has a water purifier body connected to the faucet body, a water purifier switch valve for controlling the opening and closing of a tap water inlet of the water purifier body, and a filter element detachably fitted into a filter cavity of the water purifier body. The double-outlet faucet can output both tap water and purified water and is convenient for replacing the filter element by a user.
