Taking the “P” Out of Splash-Back
Re-Inventing Public Sanitation Solutions
Sam Rabb, Jim McLaughlinENGN1000- Brown University
Proposal PresentationFebruary 17, 2011
The Problem• Existing surfaces of male restroom fixtures do
not achieve desired level of sanitation
Background: “Virtually No Splash” Solutions- Part 1
• Pros– Inexpensive
• Cons– NOT effective– Not efficient
Background: “Virtually No Splash” Solutions- Part 2
• Pros– Simple and inexpensive
• Cons– User reliant– Not very effective
Background: Waterless “Clean/Green” Solution
• Pros– Green
• Cons– Clean?– Expensive
Background: Anti-Splash Backguard
• Pros– Inexpensive– Easily integrated
• Cons– Hard to clean– Replaced often– Costs add up
Our Proposed Solution
• A stand-alone urinal that eliminates splash-back via improved geometry and materials
Engineering Theory
• Understand and model fluid impact and flow• Understand and utilize fluid interaction with
various materials
Engineering Technology
• Stators/Vanes• Materials
Engineering Design
• Splash must be eliminated• Ergonomics must be maintained• Maintenance requirements/Water usage must
be optimized over each iteration
