Integrated Air-Gap Faucet Base for Dishwasher Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-gap devices installed in plumbing systems for dishwashers require additional counter top openings and cannot be placed adjacent to the sink, leading to noise, unsightliness, and inefficiencies in draining contaminated water back into the dishwasher.
Innovation Solution
A modular air-gap device integrated within a faucet base housing, featuring flow channels, a fixed block wall, and a removable block cover forming an air-gap channel in fluid communication with ambient, allowing for installation without additional counter top openings and facilitating easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional air-gap device is installed in the plumbing waste line, then backflow prevention is achieved, but additional counter top openings and complex installation are required
Solution Approach 1:
The air-gap device is merged with the faucet assembly, combining two separate functions (backflow prevention and water dispensing) into a single integrated unit. This eliminates the need for separate installation of conventional air-gap devices and reduces counter top modifications to a single opening.
2Reliability
If the air-gap device is located away from the sink, then backflow prevention is effective, but noise and unsightliness increase
Solution Approach 1:
The air-gap device is merged with the faucet assembly, allowing it to be positioned immediately adjacent to the sink. This integration eliminates the harmful effects of noise and unsightliness associated with distant placement while maintaining backflow prevention effectiveness.
3Device complexity
If the air-gap device is integrated into the faucet, then installation simplicity and aesthetics are improved, but maintenance accessibility must be ensured
Solution Approach 1:
The air-gap device is segmented as a removable component within the faucet assembly. This allows the air-gap mechanism to be easily accessed, removed, and maintained separately from the main faucet body, ensuring ease of repair while maintaining integration benefits.
Solution Approach 2:
The air-gap device is pre-configured with removable covers and clear access paths during manufacturing. This preliminary preparation enables easy maintenance without requiring complex disassembly procedures, addressing accessibility concerns before the device is installed.
4Device complexity
If a single counter top opening is used, then installation complexity is reduced, but the air-gap device must be compact
Solution Approach 1:
The air-gap device is nested within the faucet assembly structure, utilizing the internal volume of the faucet body. This nesting approach allows the air-gap mechanism to be compact and integrated without requiring additional counter top openings or increasing overall device footprint.

AI summary
An air-gap device integrated within a faucet base of a faucet fixture for use with a dishwashing device is disposable on a counter surface and includes: a base forming flow channels adapted to provide a fluid-tight seal at the surface; a fixed block wall extending from the base, the fixed block wall separating a first pair of flow channels from a second pair of flow channels and providing a fluid-tight seal for the first pair of the flow channels; and a removable block cover selectively attachable to the fixed block wall to fluidicly couple the second pair of flow channels, the block cover further forming an air-gap channel in fluidic communication with ambient. Modular design permits removal of the faucet and valve portion to access the air-gap device for maintenance, without the need to disconnect any fluid supply or waste lines.
