Urinals TRIZ Cases

Variable rim curvature directs high-energy whirl flow to prevent splash and improve waste discharge.

A 2.5 litre water closet uses optimized rim holes and trap-way geometry to direct water flow for effective bowl cleaning.

A ceramic pressure-flushing nozzle uses a venturi tube to create negative pressure for water mixing.

Segmenting the flush valve into a permanent housing and a self-contained module eliminates complex field repairs and reduces labor costs.

Segmented cylindrical odor trap unit allows removal through the drain opening, resolving cleaning difficulties in wall-mounted urinals.

Segmenting rim and jet flows maintains siphoning capability while reducing flush volume.

A urine flow meter uses a siphon tube and solenoid valve to automatically flush the collection container after measurement.

A unified housing merges the fan, filter, and trigger element to simplify installation and protect components from rinsing water damage.

Segmenting the flush system into two independent paths allows selective valve activation, reducing water waste while maintaining high cleaning efficiency.

A urinal sanitation device ejects liquid agents to dissolve chemical inhibitors within the trap unit.

Guide parts create specific swirling flows that push waste into the discharge channel, resolving degraded performance in compact bowls.

Winding section positioning transforms turbulent flow to laminar regime, reducing flushing water volume below 0.8 liters while maintaining compact dimensions.

A pivotable flush reservoir pivots to dispense stored water through a manifold, resolving low-volume cleaning challenges.

Integrated sensors in a smart urinal analyze urine characteristics directly during voiding, eliminating laboratory visits and reducing time loss.

A timed pressure equalization member breaks the siphon in a pressurized trapway to reduce water loss during the refill cycle.

A flush water distributor divides flow into sections, using a central guide surface to throttle water and improve siphon flushing performance.

Maps sequence numbers to congestion window sizes in mobile ad hoc networks, restoring the window after packet loss detected via duplicate ACKs.

Segmenting the ceramic flush distributor into a removable plastic component simplifies production and enables easy cleaning access.

A self-cleaning toilet assembly uses a reservoir and flow control device to deliver cleaning agent doses through the flush valve mechanism.

A battery management system estimates individual cell voltage from pair measurements to identify defective alkaline batteries.

A cross beam joins the opening edge to the side wall of a ceramic toilet skirt.

Segmented trapway design prevents liquid spillage during maintenance while eliminating recesses prone to vandalism.

A urinal module uses a closed cooling circuit to form an ice layer on the contact surface.

A rimless toilet pan uses a flow balancer projection to direct water streams along the centreline.

Asymmetric side conduits with different diameters direct water streams to converge at a specific point, preventing splashing caused by equal force convergence.
