Compact Multi-Function Lavatory Fixture for Mess-Free Handwashing
Here’s PatSnap Eureka !
Summary
Problems
Conventional lavatory systems require additional space for separate soap dispensers, faucets, and hand dryers, leading to an undesirable mess due to excess soap and water drips when users move between stations during hand washing and drying.
Innovation solutions
A multi-function fixture that integrates soap, water, and air dispensing capabilities over a single basin, with sensors and visual indicators to guide users and prevent simultaneous air and water dispensing, allowing for a compact and efficient hand washing and drying experience without the need for additional space.

General conflict description:
Principle concept:
If separate soap dispensers, faucets, and hand dryers are used, then each function can be performed independently, but additional space per user is required and mess increases due to movement between stations
Why choose this principle:
The patent combines separate fixtures (soap dispenser, faucet, hand dryer) into a single integrated fixture mounted over the basin. The fixture includes a soap dispensing outlet, a water outlet with faucet, and a hand dryer outlet, all integrated into one structure that occupies minimal space and eliminates the need for users to move between separate stations.
Principle concept:
If separate soap dispensers, faucets, and hand dryers are used, then each function can be performed independently, but additional space per user is required and mess increases due to movement between stations
Why choose this principle:
The integrated fixture serves multiple functions simultaneously: dispensing soap, providing running water, and drying hands. This multi-functional design allows a single fixture to replace what would traditionally require multiple separate fixtures, thereby reducing the space required per user while maintaining all necessary handwashing and drying capabilities.

Abstract
Systems and methods for a multi-function lavatory fixture are disclosed. The lavatory fixture includes a first and second leg, where a first end of each leg is configured to be mounted to a deck and a second end of each leg is located over a basin of the lavatory fixture. A connecting section extends between the second ends of each leg and includes outlets to dispense water, soap, and air to wash a user's hands. The fixture also includes indicators located proximate each of the outlets to indicate to the user the location of each outlet. A sensor located near each outlet identifies the presence of a user's hands near the outlet and dispenses water, soap, or air accordingly. A controller within the lavatory fixture receives inputs from each sensor and activates the appropriate pump, fan, valve, and the like to deliver the desired product at the appropriate outlet.
