Drawing-Off Water Installations TRIZ Cases
- Two-Outlet Hydrant Flow Channel for Low Pressure Loss
A tapered channel and low-zeta shut-off element let a two-outlet hydrant maintain high throughput with minimal pressure loss.
- Industrial Hydrant Pilot Valve Layout for High-Flow Reliability
A large main valve paired with a smaller pilot valve boosts hydrant flow while reducing chattering, leaks, and failure risk.
- Fire Hydrant Adapter Cap With Polymer Skirt for Wireless Monitoring
A metal-polymer hydrant cap preserves torque transfer while letting wireless signals pass for remote open-close status monitoring.
- Flexible Curb Stop Alignment for Settling-Resistant Valve Access
Flexible tabs keep a curb stop box aligned with buried shut-off valves despite settling, while limiting debris ingress and avoiding digging.
- Flexible-Tab Curb Stop Box Alignment for Buried Valves
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.
- Self-Leveling Vibration Sensor Assembly for Vertical Nozzle Cap Alignment
A weighted inner housing uses gravity to keep a fire hydrant nozzle cap vibration sensor vertical, improving signal-to-noise ratio for leak detection.
- Remote Fire Hydrant Actuation for Blocked-Access Operation
A motorized wireless hydrant attachment turns the operating nut remotely when crowds or hazards block manual wrench access.
- Retrofit Water Station Filter Access for Low-Cost Upgrades
A removable panel and filter kit let existing water stations add filtration later while making filter replacement faster and simpler.
- Water Recirculation Cooling for Consistent Cold Dispensing
Periodic pump-driven recirculation through a heat exchanger keeps reservoir water cold and reduces lukewarm dispensing.
- Hydrant Riser Pipe Threading for Precise Height Adjustment
Segmented threaded zones on the riser pipe enable quick coarse and fine hydrant height adjustment with less rotation and precise positioning.
