Building Rescue TRIZ Cases
- Self-locking descender with tapered notch for small ropes
A self-locking descender uses a tapered notch to route rope through friction passages, creating automatic clamping under user weight.
- Angled Blade Rescue Tool Bypassing Blocker Plates
Asymmetric angled blade pivots to bypass blocker plates, reducing response time by eliminating bulky separate tools.
- Abseiling Device Torque Limiter for Rescue Safety
Mechanical torque limiter decouples drive means when threshold exceeded, preventing injury and component damage during rescue operations.
- Hydraulic Device Rotary Shaft Connection Mechanism
A hydraulic device connects rotary shafts using a guide shaft with projections and recesses for rapid assembly.
- Rappel Device Friction Adjustment Mechanism
A rappelling device adjusts rope friction through movable tabs and extension openings for precise load control.
- Safety Lowering Device Automatic Locking Mechanism
- Gravity Friction Descent Device for Emergency Egress
Fixed friction surfaces enable auto braking during emergency descents, eliminating debris-induced failures common in mechanical systems.
- Flexible Elastomeric Liner Panels for Hopper Flow Blockages
Elastomeric liner panels with flexible fins prevent bulk material sticking in hoppers, reducing equipment wear and maintenance downtime.
- Multi-Function Hand Tool with Nested Rotational Mechanism
Nested rotational mechanisms and dual contact tips enable rescuers to apply controlled blunt force and cut seatbelts without the bulk of larger instruments.
