Water Closets TRIZ Cases

Telescopic bolt sections adjust length to fit varying subfloor thicknesses, eliminating the need for hand tools in confined installation spaces.

A toilet tank mounting assembly uses a rounded nut portion and concave gasket surface to form a ball-and-socket joint for precise alignment.

Pneumatic reservoirs force water into bowls, eliminating bulky elevated tanks and leak-prone flapper valves.

An adjustable bolt and cap assembly eliminates cutting operations by accommodating floor thickness variations through a sliding flanged nut.

A mounting device integrates two optical units to provide general illumination and operational state indication through a translucent cover.

Universal module carriers with adjustable height mechanisms reduce warehousing needs by replacing multiple fixed variants with a single adaptable platform.

A coupling device joins frame bars using a leaf spring and control member to secure connections.

An extension tube raises aircraft waste lines above the cabin floor, resolving ergonomic stress and sealing complexity.

A concealed cistern uses a resilient locking element to secure an inspection shaft via positive engagement.

Pivoting the sanitary body moves a single cleaning nozzle to cover the entire inner surface, reducing device complexity and failure risk.

A trap valve assembly uses an eccentric pivot gate to minimize abrasion on the sealing gasket.

Modular stainless steel floor panels with integrated drainage and detachable coupling mechanisms for bathroom waterproofing.

A water closet bolt features a visual orientation notch and dedicated hold-back surface for secure installation.

An arch-shaped plunger collapses to fit narrow waste ports, directing force into clogs while sealing siphon jets to prevent splashback.

Inverted S-shaped overflow channel prevents dirty water leakage by diverting fluid through a siphon structure when blockage occurs.

Segmented L-shaped brackets with arcuate slots enhance lateral tolerance and forward support forces while preventing deformation-induced instability.

A hybrid toilet combines solid surface housing with a stainless steel P-trap assembly to deliver residential aesthetics in institutional settings.

A flush toilet discharge conduit uses a delaying flow passage to merge leading flush water with the main waste conveyance flow.

Air-space suction mechanism prevents cross-contamination during automated urine sampling while liquid-level sensing ensures accurate sample positioning.

An automated device feeds and removes urine from a test strip via movable elements, eliminating manual immersion steps.

Removable decorative panels on a universal mounting frame enable non-destructive cistern access, resolving tile removal complexity.

A compression-type nozzle connector assembly secures fluid delivery components to vitreous toilet rims using adjustable ferrule fittings.

A fitting assembly uses adjustable crossbars and a curved installation pipe to route supply hoses.

Replacing metal frames with fiber-reinforced plastic eliminates corrosion and assembly time while sustaining load-bearing capacity.

Parallel gaps in the connector receive open profile walls to prevent deformation during cutting.

Grooves and ribs on a pipe clip enable six axial positions, resolving tightness issues from limited adjustment range.

A portable toilet system uses a mobile unit and stationary docking station to enable automated flushing and sewer discharge.

A jet pump unit amplifies water flow rate through throat pipe dynamics to supply wash water.

A water flush toilet uses ultrasonic sensors to determine bowl status and automatically adjust flush volume.

An enclosed siphonic bypass eliminates exposed ligature purchase points while preserving efficient waste removal in secure institutional settings.
