Drawing-Off Water Installations TRIZ Cases

A tapered channel and low-zeta shut-off element let a two-outlet hydrant maintain high throughput with minimal pressure loss.

A large main valve paired with a smaller pilot valve boosts hydrant flow while reducing chattering, leaks, and failure risk.

A metal-polymer hydrant cap preserves torque transfer while letting wireless signals pass for remote open-close status monitoring.

Flexible tabs keep a curb stop box aligned with buried shut-off valves despite settling, while limiting debris ingress and avoiding digging.

Flexible tabs keep a curb stop box aligned with a buried shut-off valve during ground settling and help block debris from the water line.

A weighted inner housing uses gravity to keep a fire hydrant nozzle cap vibration sensor vertical, improving signal-to-noise ratio for leak detection.

A motorized wireless hydrant attachment turns the operating nut remotely when crowds or hazards block manual wrench access.

A removable panel and filter kit let existing water stations add filtration later while making filter replacement faster and simpler.

Periodic pump-driven recirculation through a heat exchanger keeps reservoir water cold and reduces lukewarm dispensing.

Segmented threaded zones on the riser pipe enable quick coarse and fine hydrant height adjustment with less rotation and precise positioning.

Separate spring and bobbin modules make blade replacement easier without disassembling the tape measure housing.

A pin support converts spindle rotation into axial pull, enabling tool-free spindle removal and installation in underground hydrants.

A reinforcing push bar and pivoting hinge provide consistent force transmission while opening access to internal dispenser components.

A journal support mechanism converts rotational movement into axial motion, enabling quick spindle assembly removal and installation.

Segmenting the operating stem from the barrel allows direct drain valve replacement without disassembling the entire hydrant structure.

An elevated hydrant armor with an inverse taper prevents snow binding and freezing, ensuring quick access during winter storms.

A yard hydrant uses a venturi to lower pressure and accelerate water flow velocity through check valves.

Plastic intermediate components resist heat transfer to prevent frost damage while metal housings maintain structural integrity.

Telescopic control pipes and check valves prevent drinking water contamination by ensuring complete drainage and blocking germ entry into the supply line.

A pivoting indicator rod on a hydrant marker base allows the display to fold flat against the hydrant body.

Segmented telescopic adapters extend rigid installation sets, resolving cost versus adaptability trade-offs.

Extraction principles separate monitoring electronics from pressurized zones, allowing microcontrollers to enter sleep modes that extend battery life.

Segmented trim pieces form a continuous J-shaped channel that seals uneven cladding and directs water away from the sillcock interface.

Curved drain tube anchors itself inside the fire hydrant barrel using clamping force, eliminating leakage risks from additional openings.

A tamper-proof water fitting uses a protective body to secure the square rod connection.

Segmented closure caps separate electronic monitoring modules from water chambers, preventing accidental leaks during maintenance.
