Building Rescue TRIZ Cases

A removable buckle-linked tool cuts a trapped seat belt strap and breaks windows when the normal release mechanism is locked.

An integrated cutter and window breaker helps occupants escape when a locked seat belt mechanism or blocked doors prevents normal exit.

A spring-biased holder in the vehicle center console keeps an emergency hammer secure under inertial loads while allowing deliberate rearward release.

A modular impact head with aligned breaking pins and a rake section boosts force on thick laminated glass while staying compact for confined escape use.

A spring-biased handle returns to neutral when released, stopping hydraulic tool operation and reducing unintended activation risk.

An acute-angle insert recess in a rescue shear blade shifts load into positive locking surfaces, improving cutting durability and reducing breakage.

Real-time video and audio guidance on the rescue tool helps operators avoid errors and work safely around vehicle safety systems.

A mobile robot pulls node-based escape routes from a server to guide people around hazards and obstacles without fixed speakers or lights.

A rotating friction element slows the rope before locking, preventing hard stops, rope damage, and injury during descent.

A selector switch changes spring-cam behavior to balance assisted clamping with smoother rope sliding during lead and top-rope belaying.

An angle gearbox, chain drive, and direct motor brake cut weight and improve heat dissipation in a high-torque portable rescue tool.

A slide hammer drives a cutting blade through vehicle sheet metal, avoiding power-source failures during emergency extraction.

A rotating housing and cam let the rope arrester stay hands-free in normal use yet lock securely when grabbed or during a fall.

A spring-biased hydraulic handle returns to neutral when released, stopping tool motion and preventing unintended operation during rescue work.

A concave rope path and movable insert prevent misinstalled connectors while maintaining braking across different rope and connector sizes.

Orientation sensing and motor-current feedback limit rescue cutter rotation under load, reducing overload, breakage, and operator risk.

On-device video and audio guidance helps rescuers avoid airbag and high-voltage hazards while reducing errors during vehicle extrication.

A V-shaped notch and convex walls let a rope descender block or release the rope with one hand while modulating braking force.

A waisted enclosed rope channel locks into grating holes to limit abrasion, handle acute angles, and prevent protector drop-out.

When hard cuts twist the blade plane, orientation sensing and motor-current control limit torque to prevent component stress, damage, and injury.

An angle gearbox and single belt drive deliver high spreading force while cutting tool weight and improving heat dissipation.

An integrated cable, tensioner, and arrestor lets ladder users stop falls and perform controlled self-rescue descent without third-party rescue.

A pivoting rocker arm and unlocking lever create local rope pinching for secure suspension and controlled descent on taut or soft ropes.

An acute-angle insert pocket secures the cutting insert without complex fasteners, lowering stress peaks and fracture risk in hydraulic shear blades.

A spring-loaded roller and one-way lock keep rope feed smooth in normal use, then lock securely under high tension or fall speed.

A movable roller and one-way rotation clamp reduce rope friction during feeding, then provide secure braking under tension in either rope direction.

Localized serrations, blade grooves, a recessed blade, and a radius striker improve wet-hand grip, precise control, and striking ease.

A gas spring stores return-stroke energy to drive the tool's initial motion quietly, cutting noise without slowing rescue intervention.

A tube-and-cap interface lets seat and net platforms swap quickly on rotary wing aircraft while avoiding strap entanglement and folded-position instability.

Real-time airbag pressure adjustment uses weight, fall distance, velocity, and wind data to reduce stunt impact forces.

An external eddy current brake and separated assembly improve line retraction response, load capacity, heat dissipation, and wear life.

Telescopic Z poles and a rope-gathered sheet enable rapid fall interception at intermediate height where cushions cannot be installed.

Inflatable window slide modules link between floors to speed high-rise evacuation, reduce effort, and support disabled occupants.

An exit-door slide uses tilt-triggered gas inflation and a silent alarm to speed upper-floor evacuation without separate escape hardware.

A one-piece steel rescue hook uses a wide-clearance cutting head to cut braided sheets or clothing while reducing weaponization risk.

Composite projections on a dense core concentrate impact force to break glass from a safe distance while reducing user exposure to shards.

Rope tension rotates a lever to create friction between rope segments, enabling automatic fall arrest without manual intervention.

Weight, platform distance, and fall velocity drive real-time airbag pressure changes to absorb impact energy during high-fall stunts.

A threaded rod, open-closing flange nut, and thrust rollers help stabilize building evacuation and simplify maintenance.

This case combines an axe, pick-head, and Halligan tool with a rope ring and beard for rapid entry and firefighter safety.

A gas-powered back end with standardized couplings supports breaking, glass penetration, and metal shearing.

This case combines a female-hand housing, light, irritant spray, and electrical shock to deter attackers without lethal weapons.

A grip, guide, and clamping pulley assembly wraps the rope for compact, portable ascent, descent, and locking without manual handling.

A curved tactical breaching claw with opposing grooved teeth prevents slippage on reinforced doors by distributing hydraulic pressure across a tapered profile.
