Sensor Faucet Valve Core With Independent Dual Water Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor faucets with dual control mechanisms face issues with water leakage due to the inability to independently control the solenoid valve water path, requiring additional on-off control devices that increase equipment costs and complexity.
Innovation Solution
The optimized valve core design incorporates a housing with a stationary disc and a movable disc, featuring arc-shaped outlet and inlet holes, and a water passage groove that allows for independent control of the sensor water output path and manual cutoff of the solenoid valve water path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated on-off control device is added between the solenoid valve input end and the valve core to prevent water leakage, then water leakage is prevented, but equipment costs increase and the faucet body requires special design with new mold
Solution Approach 1:
The patent merges the on-off control function into the existing valve core structure by designing the water passage groove and movable disc to enable manual cutoff of the solenoid valve water path. This integration eliminates the need for a separate dedicated on-off control device, reducing equipment complexity while maintaining water leakage prevention capability.
Solution Approach 2:
The valve core is designed to perform multiple functions: it controls both the mechanical water output path and the sensor water output path, and includes the capability to manually cutoff the solenoid valve water path. This multi-functionality eliminates the need for additional specialized components, reducing overall device complexity.
2Adaptability or versatility
If two independent water output paths are designed in the valve core to avoid interference between mechanical control and solenoid valve control, then control independence is achieved, but the structure becomes more complex
Solution Approach 1:
The patent segments the water passage into two independent paths within the valve core: one path for mechanical control and another path for sensor control. The water passage groove is specifically designed to enable independent control of each path, allowing the movable disc to selectively communicate with different outlet holes. This segmentation achieves control independence while integrating the functions within a single valve core structure.

AI summary
A valve core having a housing, a stationary disc, a movable disc, and a valve stem; the stationary disc and the movable disc are installed in the housing; there are two inlet holes and two outlet holes on the stationary disc; the two outlet holes are two arc-shaped holes at upper and lower portions of the stationary disc, and the two inlet holes are provided at left and right portions of the stationary disc and within an area of circular enclosure defined by the two outlet holes; the movable disc is movably and sealingly engaged with the stationary disc; the movable disc has a water passage groove; the valve stem is inserted into the housing to drive the movable piece to slide and/or rotate on the stationary disc.
