Tunnels TRIZ Cases
- Tunnel Boring Machine Cutterhead Assembly for Composite Section Excavation
Segmented main and auxiliary cutters excavate composite tunnel sections, resolving internal space utility versus construction cost trade-offs.
- Tunnel Boring Machine Segmented Body Control for Sharp Curve Alignment
A tunnel boring machine uses segmented body sections with independent grippers to follow curved paths.
- Mine Vehicle Boom Trajectory Planning for Collision Avoidance
Boom trajectory planner generates collision-free paths by processing target pose, geometry, and obstacle data before execution.
- Tunnel Widening Housing System for Continuous Railway Operations
Segmented housing isolates construction zones from active tracks, allowing 24-hour widening operations without full tunnel closures.
