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.

A gear-driven trip lever assembly uses a clutch cam to manage flush lever operation, resolving limited user control over flapper valve timing.

A dual flush adapter converts single flush valves using a clamp and gasket mechanism to enable adjustable water usage settings.

An off-center force compensating wheel dynamically adjusts mechanical advantage, matching linear actuator force to variable flush valve loads.

A concealed cistern integrates a segmented actuator system to manage flush volume while housing a fan for odour extraction.

Triple wall movable elements form annular air seals that reduce control effort and prevent permanent leakage during siphonic flushing cycles.

A toilet handle assembly uses a hexagon connecting portion and groove system for quick installation across various tank positions.

An air injection device inside a dry compartment uses gas lift to propel water, eliminating noisy external pumps and reducing space occupancy.

A glass-based enamel coating on plastic substrates resolves chemical resistance and vandalism trade-offs in concealed cisterns.

An air-exposed inlet port channels water directly to the discharge, preventing dirt accumulation on valve seats that causes backflow failure.

Segmented return element with angled spring section reduces volume while maintaining reliable resetting.

A portable toilet uses a pressurized flush tank and manual pump to deliver fluid through a spout.

A toilet ventilation device uses a movable shutter to extract foul air through radial windows.

Segmented actuating plates on a support element resolve the trade-off between device complexity and user customization needs.

A concealed flushing device connects to pressurized water lines using electrically actuated valves and an air inlet safety mechanism.

A flushing device synchronizes overflow tube width with small flush float positioning via a rib and lug guide system.

A soft-touch double-drain valve uses position-limiting mechanisms to control inner tube movement for precise drainage.

A tension load spring stores energy from seat descent to pull a flushing wire and open the drain hole.

A flush valve piston cap uses a semicircular groove to equalize pressure across the translating piston.

A side-mounted detection sensor directs electromagnetic waves vertically downward through a housing gap to identify users.

An elastic hinge connects the control plate to the counterplate, enabling easy access for maintenance while maintaining secure mounting reliability.

Gate and data line protrusions create fixed spacers that prevent light leakage caused by irregular ball spacer distribution.

Laterally projecting bearing tabs on the actuator support structure reduce wall protrusion while maintaining mechanical strength.

A toilet cistern drain fitting uses a single retaining pawl to actuate separate full and partial flushing control units.

A flush water tank uses a cylindrical body and switching valves to adjust opening surface area for multistage water volume control.

Partition openings equalize pressure in the float chamber, reducing mechanical closing force and resolving limited adjustability for full-volume flush settings.

Motor-driven axial translation of the relief valve element replaces solenoids to eliminate corrosion and ensure consistent flush timing.

Adjustable conical throttling segments regulate flushing water flow through a cistern drain fitting.

A single motor drives full and partial flushing levers via a coupling element, reducing device complexity while extending motor service life.

A control device adjusts flushing liquid volume based on past usage patterns to optimize resource consumption in sanitary systems.

Translational movement and pivoting of the actuating plate resolve accessibility issues for refilling concealed cistern containers.

A foot pedal activates a gear assembly to pull the toilet handle down without hand contact.

An adapter system manages flush capabilities by receiving sensor signals and generating control outputs for multiple toilets.
