Elevators TRIZ Cases

A testing device connects a lift speed limiter to the car brake trigger mechanism to verify activation force requirements.

A multicar elevator system uses a reservation shaft to route cars around blocked sections.

Solenoid actuator positively engages safety wedges without guide rail dependency, reducing energy consumption.

A modular elevator assembly uses guide rails with integrated connection structures for rapid on-site stacking.

A lift rope catch mechanism uses an external actuating element to enable functional testing without dismantling the safety device.

Segmented adhesive sill markers with integrated light sources detect vertical misalignment between cabin doors and landing platforms.

A U-shaped release tool uses an operating screw to exert force on a rider, mechanically disengaging blocked elevator safety gears.

Elevator control system dynamically defines service sectors using car usage data to optimize allocation.

Scanning apparatus collects structural data to form digital models, resolving installation deviations and ensuring precise component alignment.

An elevator control device generates stop floor information to provide voice announcements about intermediate stops before reaching the destination.

A swing jaw biased into a tripped position engages a ratchet disc to halt an elevator during overspeed conditions.

A nonlinear eddy-current overspeed brake generates a sharply increasing force to trigger emergency stopping.

A controller reassigns elevator calls to other cars when door reversal counts exceed a set threshold.

Segmented pre-fabricated elevator modules eliminate time-consuming on-site construction through sequential vertical stacking.

Camera captures car operating panel illumination to identify light source deviations without removing the elevator from service.

Multi-plane sensor arrays detect personnel entering elevator pits, balancing detection reliability against device complexity through spatial segmentation.
