Dual-Outlet Faucet Terminal Layout for Stable Purified Water Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water outlet devices with dual modes for raw and purified water require complex structures and linkage mechanisms, leading to smaller water cavity volumes, reduced flow rates, and instability at low pressures.
Innovation Solution
A water outlet terminal design featuring independent raw and purified water inlet cavities on the same side of the mandrel, with separate outlet holes and switching members allowing for independent operation of both waterways, enhancing flow rates and stability by simplifying the structure and eliminating linkage dependencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If linkage mechanism is used to control purified water and raw water switches, then water discharge control is achieved, but device complexity increases
Solution Approach 1:
The patent divides the water outlet system into independent purified water and raw water channels, each with its own switch. The mandrel is segmented with separate cavities for purified water and raw water, allowing independent control without linkage mechanisms. This segmentation eliminates the complexity of coordinated switching while maintaining dual water outlet functionality.
2Adaptability or versatility
If purified water cavity and raw water cavity are disposed on both sides of the mandrel, then water outlet modes are achieved, but water cavity volume decreases
Solution Approach 1:
The patent merges the arrangement of purified water cavity and raw water cavity onto the same side of the mandrel rather than distributing them on opposite sides. This spatial consolidation maximizes the available volume within the mandrel structure, increasing water cavity volume while still accommodating both water types and their respective outlets.
3Volume of stationary object
If water cavity volume is reduced, then mandrel thickness constraint is satisfied, but water flow rate decreases
Solution Approach 1:
The patent optimizes the three-dimensional arrangement of water cavities within the mandrel, utilizing spatial efficiency in multiple dimensions. By strategically positioning the purified water and raw water cavities on the same side and optimizing their internal geometry, the design maximizes water cavity volume within the thickness constraints, thereby maintaining adequate water flow rates.

AI summary
A water outlet terminal with the function of purified water outlet, includes a body and a mandrel. A raw water outlet hole and a pure water outlet hole are arranged on the end surface of the mandrel. The mandrel has a raw water inlet cavity and a purified water inlet cavity which are independent from each other. One end of the raw water inlet cavity and the purified water inlet cavity are communicated with the raw water outlet hole and the purified water outlet hole, and the other ends are the raw water inlet hole and the purified water inlet hole. The water outlet terminal has a purified water opening member with a first position and a second position corresponding to an open or closed state of purified water inlet hole, a cover assembly, with a purified water outlet passage in the geometric center of the assembly.
