Flushing Devices TRIZ Cases

A motorized toilet unit uses a single motor to drive a pump and macerator in opposite rotation directions.

A toilet flapper kit uses adjustable mounting legs and a cylindrical bar to attach securely to various flush valve configurations.

A universal canister flush valve uses a modular float extender to adjust overflow height and buoyancy for diverse toilet configurations.

An air pump and control board retrofit existing toilets to enable automatic sensory flushing without replacing the entire unit.

An adjustable closure member modifies the float chamber volume, enabling a single flush valve model to accommodate different toilet assemblies.

Timed bowl fill valve prevents excess water waste by closing after the tank refills.

A toilet tank water supply system uses a hydraulic actuator to open the drain valve via flowing water.

Separating the exhaust fan from the water zone eliminates splash protection needs while enabling easy filter replacement via an inspection opening.

A precipitation reclamation system uses a downspout adapter to direct runoff into a reclamation chamber equipped with a pump for water delivery.

Sliding mounting plates with elastic locking members resolve complex installation contradictions by enabling adjustable height positioning.

A hybrid sensor arrangement uses a low-energy presence detector to activate a time-of-flight sensor only when needed.

Angled bleed openings in the hollow float manage water entry for precise closure timing, while a serpentine seal groove prevents leakage at the float interface.

A compact pressure flushing system creates a water shock wave using a gas hydraulic accumulator and automatic valve.

Preset settings in the permanent body maintain flush volume accuracy during module replacement, eliminating user adjustment complexity.

An infrared sensor wakes an ultrasonic sensor to verify hand proximity, eliminating false triggers from ambient light while reducing power consumption.

Segmenting the float compartment prevents continuous water intake when the outlet valve leaks, conserving supply.

Projecting push plates resolve the contradiction between compact front profiles and ease of operation in concealed dual-flush cisterns.

Segmented shrouds and two-stage flush systems reduce bacterial odor and noise in vacuum toilets.
