Integrated Two-Handle Faucet Control for Easier Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-handle automatic faucets require separate installation of a control box with solenoid valve core and controller, making the installation process more cumbersome for users.
Innovation Solution
Integrating the solenoid valve core and controller directly into the faucet body, eliminating the need for a separate control box, and incorporating a sensor with two sensor probes for convenient water control modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the solenoid valve core and controller are installed on a separate control box, then the control functions are achieved, but the installation process becomes more cumbersome and complex
Solution Approach 1:
The patent merges the solenoid valve core and controller into a single integrated control assembly that is pre-installed within the faucet body. This combination eliminates the need for separate control box installation, reducing installation steps and complexity while maintaining all necessary control functions for automatic water flow management
2Device complexity
If a separate control box is used for solenoid valve core and controller, then the control functions are separated, but the number of installation components increases
Solution Approach 1:
The control assembly integrates the solenoid valve core and controller into a unified component that is pre-installed in the faucet body. This merging reduces the total number of separate components that need to be installed and connected, simplifying the installation process while maintaining functional separation through internal design
3Ease of operation
If mechanical valve cores are used for cold and hot water control, then the water flow control is achieved, but the user operation becomes more inconvenient
Solution Approach 1:
The patent replaces manual mechanical valve core operation with an automatic solenoid valve core controlled by a controller. The controller receives signals from sensors or user input and automatically actuates the solenoid valve core to control water flow, eliminating the need for manual manipulation of mechanical valve cores and improving operational convenience

AI summary
A two-handle automatic faucet includes a faucet body, a solenoid valve core, a controller, and a sensor. The solenoid valve core, the controller and the sensor are mounted to the faucet body. The controller is electrically connected to the solenoid valve core and the sensor. The controller controls action of the solenoid valve core according to a sensor signal of the sensor, so as to correspondingly control water flow of the two-handle automatic faucet. The controller and the solenoid valve core are installed to the faucet body, thus, it is convenient for a user to install the finished product of the two-handle automatic faucet.
