Elevator Control System Automatic Service Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems require manual interaction from passengers to request special transportation services, which can be inconvenient, especially for VIPs or handicapped individuals.
Innovation Solution
A wireless transmitter device located near the elevator interacts with a passenger's ID device to automatically recognize and fulfill special transportation service requests, adjusting elevator parameters such as door opening time, acceleration, and car size based on the service type, without manual input from the passenger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual interaction is required from passengers to request special transportation services, then the elevator system can accurately identify service needs, but the ease of operation deteriorates especially for VIPs or handicapped individuals
Solution Approach 1:
The system uses automatic recognition technology where the elevator control system autonomously identifies passengers requiring special services through RFID tags, biometric sensors, or camera recognition. The system self-determines service parameters (door opening time, acceleration, car size) without manual input from passengers, eliminating the contradiction between ease of operation and service request accuracy.
Solution Approach 2:
Passenger identification data is pre-stored in the elevator system's database with associated service parameters. When a passenger approaches or enters the elevator, the system proactively retrieves and applies the appropriate service configuration before the passenger needs to request it, ensuring both automatic accuracy and operational ease.
2Adaptability or versatility
If the elevator system automatically adjusts operating parameters for special services, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The elevator control system integrates multiple functions into a single unified controller that handles both standard and special transportation services. The control system universally manages diverse service types (wheelchair access, VIP service, blind person assistance) through a common architecture, achieving high adaptability without proportionally increasing device complexity.
Solution Approach 2:
The system achieves adaptability by dynamically adjusting operational parameters (door opening time, acceleration, car size selection) rather than requiring separate hardware configurations for each service type. This software-based parameter modification allows versatile service adaptation while maintaining relatively simple physical device architecture.
3Ease of operation
If the transmitter device is located in the vicinity of the elevator system, then the ease of operation improves for automatic recognition, but the loss of time may increase for system setup and configuration
Solution Approach 1:
Transmitter devices and identification systems are pre-installed and configured in the elevator system during initial setup. Passenger identification data and service parameters are pre-loaded into the system database before operation begins. This preliminary configuration minimizes setup time while enabling immediate automatic recognition and ease of operation during actual use.

AI summary
The invention refers to an arrangement for the allocation of destination calls in an elevator system with at least two elevators, comprising a wireless transmitter device connected with an allocation control of the elevator system. The transmitter device interacts within a certain mutual distance with a wireless ID device carried by a passenger, which ID device is configured to transmit to the transmitter device an ID which is linked with a special transportation service in the elevator system. The elevator system comprises a memory with correlated operation parameters of the elevators which are linked to the particular special transportation service request of the ID device, whereby the ID device is configured to transmit ID data and/or a call with a departure floor and destination floor to the allocation control. The transmitter device is located within a transmitter accommodation space located at least in the vicinity of an elevator, whereby the transmitter device is located in the vicinity of a tag carrying a symbol correlated to the special transportation service.
