Modular faucet system for aircraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft lavatory faucets face stringent regulatory requirements, limiting options and increasing costs for testing and certification, which hinders customization and maintenance due to the integration of decorative and functional components.
Innovation Solution
A modular faucet system is introduced, separating decorative components from the complex electrical and fluid system components, allowing for easier customization, maintenance, and reduced testing costs by enabling individual installation, removal, and inspection of touchless faucet components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If decorative and functional components are integrated in a single faucet unit, then structural simplicity is maintained, but customization options are limited and maintenance becomes difficult
Solution Approach 1:
The faucet system is divided into separate functional modules: a decorative faucet outlet assembly and a functional valve assembly. The decorative assembly includes the visible faucet body and trim, while the functional assembly contains the flow control valve and actuator. This segmentation allows independent selection and replacement of decorative elements without affecting functional components, enabling customization while simplifying maintenance operations.
2Ease of repair
If all faucet components are installed as a single integrated unit, then installation is straightforward, but individual component inspection and replacement are difficult
Solution Approach 1:
The faucet system separates the decorative outlet assembly from the functional valve assembly, allowing the functional components (valve, actuator, sensors) to be accessed and maintained independently. The decorative assembly can be removed without disturbing the functional components, enabling easy inspection, repair, or replacement of individual parts while maintaining a simple overall installation process.
Solution Approach 2:
The functional valve assembly is extracted as a separate removable unit from the decorative faucet outlet. This extraction allows maintenance personnel to access and service the functional components (flow control valve, actuator, touchless sensors) without removing the entire faucet assembly, significantly easing repair operations while keeping the installation process straightforward.
3Reliability
If a complete faucet system is tested and certified as one unit, then regulatory compliance is ensured, but testing and certification costs increase
Solution Approach 1:
The faucet system is designed with separable functional modules that can be tested and certified independently. The decorative outlet assembly and functional valve assembly can each be evaluated for their respective functions, allowing manufacturers to obtain certification for standardized functional components once, then reuse that certification across multiple decorative variations, significantly reducing testing and certification costs while maintaining regulatory compliance.

AI summary
A modular faucet system for an aircraft comprising a faucet outlet, a flow valve, and an actuator. The faucet outlet is configured to be installed on the aircraft. The flow valve is configured to be installed on the aircraft separately from the faucet outlet, to be connected by a first water line to a water supply comprising a water tank on the aircraft, and to be connected by a second water line to the faucet outlet. The actuator is configured to be installed on the aircraft separately from the faucet outlet and the flow valve. The actuator comprises a touchless sensor that is configured to detect a user of the modular faucet system. The actuator is configured to generate a control signal to open the flow valve to provide water from the water supply to the faucet outlet in response to detection of the user by the touchless sensor.
