Elevators TRIZ Cases
- Elevator Car Dispatch Balancing Response Time and Wear
Elevator controllers score health, usage, and travel time to balance service response with component wear across the car bank.
- Pulley-Assisted Elevator Landing Door Unlocking for Shaft Pits
A support-rod pulley and tension member redirect downward force to unlock shaft-pit landing doors with less manual effort and fewer operations.
- Elevator Action Control Using Radar Micro-Doppler Classification
Radar micro-Doppler signatures classify moving objects in an elevator car, replacing complex sensor arrays and privacy-sensitive cameras.
- Machine-Learning Installation Operations for Lower Call-Out Rates
Historical installation data trains a machine-learning module to detect site issues and generate software, parameter, or feature updates during installation.
- Drive Safety Interface Board Architecture for Scalable STO and SBC Control
A monitored DSIB unifies STO and SBC circuitry to reduce integration and certification burden across elevator drive portfolios.
- Elevator Dispatching Balancing Travel Time And Component Wear
An elevator controller weighs car health and usage against travel time to improve response while balancing wear across elevator components.
- Wireless Elevator Landing Fixture Addressing via Car Identification
Wireless identification from the elevator car lets landing fixtures store unique addresses automatically, reducing manual programming time and errors.
- Preassembled Elevator Shaft Top Module With Shiftable Guide Rails
Preassemble guide rail pieces and the drive unit in transport positions, then shift them into operating positions to simplify elevator installation.
- Voice-Activated Elevator Interface Configuration Without Specialized Tools
Voice input configures elevator passenger interfaces without specialized tools, while role-based access manages customization complexity.
- Elevator Call Reassignment Through Mobile Boarding Detection
Mobile location tracking identifies boarding intent, enabling elevator reassignment when unregistered passengers risk overcrowding.
- Elevator Stuck Detection Through Correction Torque Monitoring
Correction torque is monitored against load and speed signals to identify stuck elevator movement and trigger a specified safety measure.
- Elevator Car Rescue Control Using Load-Based Run Selection
A load sensor selects balanced or unbalanced elevator rescue runs, reducing battery power needs while maintaining smooth movement to a landing.
- Single-Occupant Elevator Emergency Detection With Posture Timing
Occupant counting and posture sensing identify one lying or crouching passenger, while a timer confirms the condition before authorities are alerted.
- Platform Lift Usage Pattern Detection for Caregiver Alerts
Comparing actual platform lift travel patterns with alert definitions helps notify caregivers when unusual usage occurs.
- Passenger Transport Energy Monitoring at Main Switch Input
Electrical sensing before the main switch detects elevator, escalator, or walkway states remotely for energy management without site access.
