Urinals TRIZ Cases

A sliding flushing nozzle uses a manipulatable cover element to shift between service and maintenance positions.

Alternating acidic and alkaline electrolytic water washes urinal walls, removing urine scale while preventing neutralization that reduces disinfection.

A women's urinal uses a concave water-repellent mesh to break urine jets and guide flow into an elongated bowl.

Snorkel float chamber design equalizes internal pressure via air intake, reducing cistern drain fitting noise during valve closure.

A flush toilet bowl uses a helical guide passage to direct swirling water flow from upper discharge ports toward the drainage outlet.

Shared scaffolding enables simultaneous adjustment of the cage and upright tube without separate adaptation, resolving complexity in installed state changes.

A toilet fixture uses a pneumatic valve to lower bowl water levels, redirecting flow to minimize splashing during use.

Segmented diaphragm geometry eliminates dead spaces in waterless urinals, preventing odor formation while maintaining back pressure resistance.

Curved bowl surface directs jet spout water flow along the Coanda effect path to maintain force.

A toilet tank device uses a flow rectifying portion to guide flush water smoothly along the inner wall surface.

Rear rim water chambers with vertical and tangential openings resolve cleaning difficulties of encircling rims while maintaining effective flushing.
