Water Closets TRIZ Cases

An adapter pin with a retaining bolt and widened cam locks via a rotatable holder, resolving ergonomic assembly issues for suspended ceramic fixtures.

A telescoping protection cap assembly secures toilet bolts using a gripping shaft and hemispherical cover.

An adjustable pedestal support system distributes bariatric loads up to 1000 pounds by combining wall-mounted faceplates with floor anchors.

A hybrid toilet bowl combines a mineral cast outer shell with a ceramic inner part to resolve material trade-offs.

A sanitary foot unit uses a pivot joint to connect the foot element and connecting element for adjustable positioning.

A bidet nozzle directs water streams for anal cleansing and enema therapy.

An electromagnet activates a rotating valve plate to maintain closure against negative pressure, preventing harmful sewer gases from entering living spaces.

A flushometer cover assembly uses a locking ring and projection to secure the housing.

Segmented float chambers disconnect the hydraulic drive clutch at specific water levels, resolving inconsistent piston descent speed variations.

A telescopic wrench with snap-fit elements adjusts length to fit wall-hung sanitary fixtures.

A flush toilet discharge passage inlet uses asymmetric width geometry to maintain swirl flow momentum.

Segmenting the base with recesses near upper and lower fastener openings reduces stress concentration, enabling loads up to 2000 pounds.

A downstream water conduit positions an inner wall surface off-center to generate rotational momentum in the rim passage.

Segmented arm segments adjust position to accommodate diverse fixture dimensions, eliminating the need for multiple specialized carriers.

A modular waxless seal uses compressive foam rings and a rubber barrier to create a pressure-tight connection between a toilet bowl and floor flange.

An inclined squatting toilet rim accommodates straddling postures while a pivotable seat maintains seated hygiene without clothing removal.

Plane-shaped magnetic attraction surfaces on a curved toilet panel prevent detachment during cleaning while enabling easy sliding and positioning.

Pivotable coupling device ears align with wall holes to prevent wing breakage during bolt tightening, simplifying installation.

Reclosable drain holes and anchor clamps enable in-place tool sanitization, preventing waste contamination during site visits.

A sliding technical frame on a fixed mounting bracket uses an elastomeric washer to hold position during installation.

An overflow flow channel merges with the water supply path to prevent odor backflow without adding ceramic weight.

Segmenting the biodegradation tank from the base reduces occupied area and prevents water damage to microbial activity during waste decomposition.

A flush toilet rim with a front spout directs water to swirl rearward, maintaining flow force along the bowl surface.

A separating toilet channels urine laterally into a side outlet using surface tension and the teapot effect.

Pneumatic ejector generates vacuum to assist gravity drainage, reducing water consumption while eliminating washroom odors.

Automated diagnostic system processes urine samples using capillary fluid transport and optical detection to deliver rapid pregnancy and kidney disease results.

Dual rim spout adapts to flow fluctuations, reducing abnormal noise and ensuring consistent washing performance.

A strap with adjustable hooks and a rounded middle portion catches non-dispersing cloths in the toilet bowl trapway.

Sloped rim segments water flow to maintain pressure and increase velocity, resolving waste discharge issues in pooled surfaces.

A toilet overflow control system uses an obstruction sensor to trigger a disconnection mechanism that separates the flush actuator from the flapper.

A flush toilet shifts the water supply portion to a side position, directing inclined flow into dual spout ports for balanced distribution.

Adjustable sleeve accommodates flange height variations to resolve installation feedback issues.

Tangential water inlet and internal thresholds prolong rotary motion, increasing momentum for thorough cleaning while reducing water volume.

Integrating the infrared generator into the rim conduit eliminates hole formation, preventing leakage and simplifying manufacturing.

Mounting blocks stabilize flange bolts during bowl placement, eliminating manual alignment struggles and reducing installer injury risk.

A suction fan draws air from the toilet rim through a discharge tube into the sewage passage.
