Tunnel/Mines Ventillation TRIZ Cases

Real-time sensors and automated branch dampers balance underground airflow, cutting fan oversizing, power use, and manual adjustment.

A motorized bypass isolates heat-sensitive conversion electronics while preserving direct fan power for fire ventilation.

An airfoil-shaped regulator prevents flow separation at the rib wall, increasing air delivery to the immediate face zone by up to 80%.

A subsea heating system prevents hydrate blockages by maintaining fluid temperature above formation points.

Underground vapor compression system eliminates long-distance pipe transport losses by placing evaporator in supply well and condenser in return well.

Merging T-piece and flange functions into one transition block eliminates complex connections, reducing assembly difficulty and material costs.

Segmented panels and spring-loaded hinges reduce door weight while enabling self-closing and reversible mounting for efficient air flow management.

Louver connections prevent end cap movement under extending forces, ensuring stable sealing engagement in mine ventilation systems.

A tunnel ventilation system uses air curtains and pumps to create a blind recirculation flow inside the tube.

An inflatable air barrier isolates mine refuge areas by using pneumatic seals and magnetic closures to minimize gas leakage without complex mechanical parts.

A vertical orthogonal top exhausting air duct structure shortens ventilation paths in deeply-buried subway stations.

A ventilation system measures airflow to regulate fan speed and maintain constant volume flow.

Segmented duct sections on a removable core assembly enable quick reloading without disrupting drilling operations, reducing manual labor and downtime.
