Flushing Devices TRIZ Cases

An electrically controllable solenoid valve directs water pressure to a pneumatic bellows, lifting the drain valve and reducing electrical energy consumption.

A hinged panel structure connects a movable cover to a fixed mounting frame, enabling rotational opening of the enclosure.

Segmenting the valve allows a short lift stroke while buoyancy assists automatic opening, resolving operation difficulty.

Door-driven piston pumps replace complex mechanisms, reducing production costs and improving reliability in sanitary cubicles.

An electronic control system replaces mechanical plates to adjust flushing parameters while a float mechanism ensures operation during power failures.

Adjustable stop unit corrects angular installation errors in cistern actuation devices while maintaining reliable button resetting.

Nested receptacles collect shower water and transfer it to the toilet tank, reducing potable water consumption without complex plumbing.

A radiused inlet reduces hydraulic turbulence while a buoyant float keeps the piston open, preventing premature closure in low-volume toilets.

An extender device uses a flexible line and lever to bridge the gap between a user and a high-mounted flush button, improving accessibility.

Optimized venturi tube geometry increases air volume intake to maintain consistent flush performance below 0.8 gallons per flush.

An emergency flush apparatus switches to battery power when primary supply fails, maintaining toilet operation.

Tapered passage and guide structure in flush valve seat direct water flow, resolving impedance from standard fittings.

A nutless flushometer valve tube-to-body coupling directly fastens the outlet tube to the valve body using integrated threading and radially extending lugs.

An ozone mitigation system reduces environmental escape by using baffles and periodic generation cycles to improve dissolution.

Universal housing receiving structures accept interchangeable power packs or converters, eliminating complex warehousing and specialized electrical maintenance.

External fill valve uses magnetic coupling to control water flow, resolving leakage risks and maintenance access constraints in concealed installations.

Segmented controller assemblies enable economical conversion of manual flush valves to automatic operation without replacing the base valve body.

Axial and vertical blocking prevents Z-axis movement of the actuating bridge, securing elements during transportation.

A universal cistern inlet valve uses repositionable coupling means to serve lateral or lower installations, reducing production costs and storage volume.

A flush water tank discharge valve uses a piston driven by hydraulic pressure to open the flow path.

A flow channel switching unit separates drying and patient air paths to prevent contamination spread from the excreta storage tank.

An adjustable float assembly with a guide member and stop member customizes flush volume while preventing sealing member deterioration.
