Inductive Two-Handle Faucet for Consistent Mixed Water Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-handle faucets for 4-inch basins require users to repeatedly adjust the temperature of mixed cold and hot water by turning handles, making them inconvenient to use.
Innovation Solution
A two-handle inductive faucet design featuring a faucet body with valve core assemblies, a sensor unit, and a control box that mixes cold and hot water to a suitable temperature, allowing the mixed water to flow consistently without needing re-adjustment, using a five-way connector and solenoid valve for controlled water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional mechanical switch faucets are used, then the structure is simple, but the user needs to repeatedly adjust the temperature and flow, reducing ease of operation
Solution Approach 1:
The patent replaces the conventional mechanical switch system with an inductive sensor system. The sensor unit detects the presence of a conductor (such as a user's hand) and triggers the control box to automatically open the valve core assemblies, eliminating the need for manual handle adjustment and improving ease of operation.
Solution Approach 2:
The faucet system performs self-adjustment through the sensor unit and control box, which automatically detect user presence and control water flow without requiring manual intervention. The system serves itself by maintaining consistent temperature and flow settings once activated, reducing the need for repeated adjustments.
2Loss of time
If manual adjustment handles are used, then the device structure is simple, but time is lost due to repeated adjustments
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated inductive control system. The sensor unit and control box work together to automatically activate and maintain water flow at consistent settings, eliminating the time users would otherwise spend repeatedly adjusting handles.
Solution Approach 2:
The system performs preliminary action by detecting user presence before water flow is needed and automatically activating the appropriate flow settings in advance, so that water is ready immediately at the correct temperature and pressure without requiring user adjustment time.
3Ease of operation
If inductive sensor and control box are added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent divides the faucet system into distinct functional modules: the sensor unit for detection, the control box for processing signals and controlling valve operation, and the valve core assemblies for water flow control. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability despite increased complexity.
Solution Approach 2:
The control box serves as an intermediary between the sensor unit and the valve core assemblies. It receives signals from the sensor unit and translates them into appropriate valve control actions, managing the complexity by providing a dedicated control layer that coordinates between detection and execution components.
4Stability of the object's composition
If automatic temperature mixing is implemented, then consistency of water temperature is improved, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical mixing adjustment with an automated control system that uses the sensor unit and control box to regulate hot and cold water flow through the valve core assemblies. This ensures consistent mixed water temperature automatically, improving stability while the modular design helps manage the associated complexity.

Implementation Method 1
a sensor unit, which protrudes from the faucet housing and is in signal communication with the control box
Implementation Method 2
the control box includes a solenoid valve therein, and the solenoid valve controls the second water inlet pipe to communicate with the second water outlet pipe

AI summary
A two-handle inductive faucet includes a faucet body, a faucet housing, a faucet base, and a control box. The faucet body is installed to the faucet housing. The faucet body includes two valve core assemblies, a first water outlet pipe, and two first water inlet pipes. The faucet body has two water inlet channels and an upper water outlet channel. The faucet housing is provided with a protruding sensor unit. When the control box receives an opening signal of the sensor unit, the control box controls water from the two water inlet channels to be mixed and then flow out through the first water outlet pipe.
