Flushing Devices TRIZ Cases

A separating element with a hydrostatic closure means prevents overflow noise during tank filling while maintaining precise flushing volume adjustment.

Segmented chambers and dynamic orbital seals prevent waste ingestion into the valve housing, resolving reliability issues caused by high differential pressure.

An upper float counterweight lifts the overflow pipe via buoyancy, reducing user activation force below 5 N and easing operation.

A flush sleeve actuator lowers a reservoir sleeve to initiate toilet flushing.

Optical sensors detect user presence and gender to automate bidet functions, eliminating physical contact with control panels that transmits bacteria.

An eccentric lateral float on a slidable valve body regulates water flow, reducing component complexity by adapting to varying tank dimensions.

A cistern fill valve uses a dedicated tank to immerse the air intake opening in water during filling, creating a hydraulic seal without mechanical parts.

Adjustable flush valve with trim line gasket fits 3.25 to 3.95 inch openings.

Hydraulic control lines transfer foot pressure to open flush valves, eliminating direct contact with contaminated surfaces in public restrooms.

A valve system outlet pipe lifts from an installation box via a detachable connection and bayonet lock.

Segmented stem and body modules enable maintenance without disassembly, resolving durability versus ease of use trade-offs.

Dual sensor activation switches a sanitary actuating element to setting mode, using color changes to prevent incorrect manipulation during parameter adjustment.

Segmented push buttons and a sliding timing piston adjust fluid volume delivery, resolving the trade-off between adaptability and device complexity.

A pneumatic actuator manages vacuum toilet air paths using pressure tanks and valves.

Segmented engagement prevents finger penetration, stopping incorrect onsite regulation of rinse water amount.

An elastic fastening element adapts toilet flappers to varying overflow pipe diameters, eliminating the need for specialized disassembly tools.

Integrated control shaft selects flushing modes via lever engagement, reducing part count and assembly complexity.

Positioning ring mediates button attachment to receiving parts, resolving flushness trade-offs against tolerance deviations.

Removable lower float segments adjust poppet buoyancy to convert between 1.6 and 1.28 gpf flush volumes without altering tank water level.

Segmented divider members prevent vortex formation and turbulence in close-coupled cisterns, ensuring sufficient flush flow rates despite reduced pressure head.

A vent cover with a curved wall diverts fluid flow within an elevated flush valve assembly.

A movable spacer sets the rear wall distance on a concealed toilet cistern to prevent actuator plate collisions during installation.

A toilet flushing mechanism lever locks a traction rod via a toothed wheel and rack assembly.
