Building Lifts TRIZ Cases
- Elevator Control Arrangement Integration in Door Frame
Merges power electronics with the elevator control unit inside the door frame chamber, eliminating separate wiring and reducing maintenance difficulty.
- Elevator Drive Unit with Asymmetric Rollers for Belt Guidance
Dual drive unit rollers on a common axis use different circumferential speeds to move elevator support means.
- Ropeless Elevator Transfer Station Carriage Redundancy
Transfer station cassette repositions carriages via linear motor to resolve redundancy bottlenecks in ropeless elevator systems.
- Machine Room-less Elevator Suspension with Segmented Deflection Rollers
Segmented deflection rollers distribute suspension strands horizontally, reducing pulley space requirements while maintaining rope reliability.
- Elevator Traction Sheave with Zoned Friction for Belt Wear
Zoned friction on the sheave resolves nonuniform contact pressure from spherical crowns, preventing localized slipping and premature belt wear.
- Vehicle Elevator System with Rotating Platform
Rotating platforms position vehicles inside elevator cars to resolve accessibility contradictions in high-density multi-story parking structures.
- Adjustable Elevator Door Engagement Device for Varying Depth Distances
An elevator door engagement device uses an adjustable engaging part to transmit driving force between car and landing doors.
- Stair Climber Platform with Overturning Mechanism for Narrow Stairs
Segmented frames and dynamic positioning reduce installation costs while preserving staircase aesthetics.
