Electronic Faucet Signal Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic faucet devices with dual operation units often confuse users when attempting to discharge or stop water, as operations on one unit do not reliably initiate or stop water flow due to conflicting signals from the other unit.
Innovation Solution
An electronic faucet device with a control unit that prioritizes electrical signals from one operation unit over the other to ensure consistent water discharge and stop operations, allowing for adjustable flow rate and temperature settings, and incorporating detection units to manage water flow based on user intent and object presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dual operation units are provided for water discharge and stop operations, then operability is improved, but signal conflicts occur causing confusion
Solution Approach 1:
The control unit serves as an intermediary that receives signals from both operation units and applies priority-based logic to resolve conflicts. When a touch operation unit and lever operation unit simultaneously send conflicting signals (one to open, one to close), the control unit determines which signal takes precedence based on predefined priority rules, ensuring consistent and predictable water flow control without user confusion
2Adaptability or versatility
If touch operation unit and lever operation unit are both used, then versatility is improved, but operation confusion increases
Solution Approach 1:
Instead of allowing both operation units to independently control water flow without hierarchy, the system inverts the expected equal-status operation by establishing a clear priority hierarchy. The control unit processes signals in a predetermined order of precedence, ensuring that even with multiple operation methods available, the system responds predictably and eliminates operational confusion through structured signal prioritization

AI summary
An electronic faucet device includes a water discharge port for discharging water mixed at a faucet main body; a valve for electrically opening and closing a passage on an upstream side of the water discharge port; a first operation unit and a second operation unit for opening and closing the valve; and a control unit for controlling the valve based on an electrical signal transmitted from each of the first and second operation units, in a case where a water discharge and stop operation is performed on one operation unit among the first operation unit and the second operation unit in a state where the water discharge and stop operation is performed on the other operation unit, the control unit controls the valve by prioritizing an electrical signal transmitted from the one operation unit so as to enable discharge and stopping of water at the water discharge port.
