Induction Faucet Switch for Automatic Manual Fallback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infrared induction control boxes for faucets require manual switching to mechanical mode when batteries are discharged, leading to a complex structure and increased costs due to the need for additional switch valves, and they cannot function as traditional faucets without power.
Innovation Solution
A switch that automatically switches the faucet to a mechanical valve mode when the induction control component is not in a working state, using a control program to detect voltage levels and an indicator light to signal low battery, allowing for seamless transition to manual mode without additional switch valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a manual switch valve is added to enable mechanical mode switching, then the faucet can function without power, but the structure becomes complex and cost increases
Solution Approach 1:
The patent combines the manual switching function with the existing solenoid valve by integrating a manual operating mechanism directly onto the solenoid valve body. This allows the solenoid valve to be operated manually when power is unavailable, eliminating the need for a separate manual switch valve and maintaining a simple water circuit structure while ensuring the faucet can function without power.
Solution Approach 2:
The solenoid valve is designed to serve dual purposes: it can be controlled electrically when power is available and operated manually when power is unavailable. This multi-functionality allows a single component to handle both powered and unpowered operating modes, reducing the need for additional components and simplifying the overall system structure.

3Ease of operation
If the induction control box uses battery power, then non-contact induction control is achieved, but the system fails when battery is discharged
Solution Approach 1:
The patent incorporates a low-voltage warning indicator that alerts users when the battery is nearing depletion. This advance warning allows users to replace the battery before complete discharge occurs, ensuring continuous reliable operation of the non-contact induction control system and preventing unexpected failure of the water supply function.

AI summary
The disclosure discloses a switch configured to switch an on-off state of a liquid flow conduit to a working mode controlled by a mechanical valve when an induction control component is detected not to be in a working state. The disclosure further discloses an induction control box including the switch, and an induction faucet including: a faucet having a automatic switch mode and a manual switch mode; a sensor arranged on the faucet; a solenoid valve arranged on a water output path and connected with the sensor, wherein when the sensor and solenoid valve are in a working state, the faucet supplies water by automatic switch mode; and a switch configured to switch the faucet from the automatic switch mode to manual switch mode when the sensor and/or the solenoid valve are detected not to be in the working state.
