Innovative urinal designs created from new solutions to differential equations governing fluid impact angles.

Experimental studies demonstrated that maintaining an impingement angle of 30° or less minimizes splashback.

Each design ensures this condition across the entire surface, resulting in dramatically improved cleanliness and user experience.

Nautilus urinal additionally accommodates a wide range of user heights, enhancing accessibility for children and individuals using wheelchairs.

If implemented widely, such designs could prevent millions of liters of urine from splashing onto public restroom floors each day, significantly reducing maintenance costs and health risks.

Unlike traditional fixtures, which have remained largely unchanged since the early 20th century, these models are engineered to eliminate urine splashback through principles of fluid dynamics and geometric optimization.

By combining mathematics and physics, splash-free urinals redefine hygiene in one of the most overlooked aspects of modern architecture.
