Building Lifts TRIZ Cases
- Stairlift Load Carrier Wedge Brake for Emergency Rotation Blocking
A flexible retaining member drives a wedge brake into engagement to stop uncontrolled stairlift load carrier rotation during emergencies.
- Narrow Elevator Doorsill Assembly to Prevent Groove Debris Trapping
A filling bar narrows the elevator doorsill groove so debris, heels, and dropped items are less likely to jam door guidance or cause trips.
- Lift Cabin With Manually Shiftable Frame for Scaffold Access
Manually shiftable frame sections move the lift cabin toward scaffolding, improving loading safety without a complex transverse drive.
- Analog Magnetic Sensor for Accurate Elevator Car-Door Position Detection
An analog magnetic sensor continuously measures elevator car-door position, improving accuracy despite mechanical tolerances and supporting smoother coupler movement.
- Elevator Door Coupler With Adjustable Landing-Door Engagement
An elongate door-hanger opening lets one elevator coupler adjust to different landing door types while preserving structural integrity.
