Elevator Hall Lantern Control for Disabled Passenger Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator systems face challenges in guiding passengers, especially disabled individuals, to the correct elevator car, and require excessive electrical capacity for hall lantern lighting when multiple cars are assigned.
Innovation Solution
An elevator system with a call receiving device that includes a destination floor receiving unit and a disabled-person-declaration receiving unit, where the group management control device determines the assigned elevator car and outputs a hall lantern lighting instruction only when a disabled person signal is detected, allowing the hall lantern to be turned on only for the assigned car, thereby reducing electrical consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the hall lantern is turned on each time when the destination floor call is inputted, then passengers can identify the assigned elevator car, but it is difficult for customers to determine which car to ride on among multiple cars with lighting hall lanterns and requires much electrical capacity
Solution Approach 1:
The patent applies local quality by providing differentiated guidance based on passenger needs. Disabled persons receive hall lantern guidance to identify their assigned car, while other passengers receive only display unit information. This selective application of lighting guidance resolves the contradiction by providing necessary information to those who need it most while minimizing energy consumption.
2Reliability
If the hall lantern is turned on for multiple assigned cars, then all assigned passengers can identify their cars, but it requires much electrical capacity
Solution Approach 1:
The patent implements partial action by providing hall lantern guidance only to disabled persons who need it, rather than to all passengers. The display unit provides information to all passengers, but the energy-intensive hall lantern is activated selectively. This resolves the contradiction by providing sufficient guidance information through alternative means while using the lantern only when necessary.
3Ease of operation
If the hall lantern is used to guide all passengers, then all passengers can easily identify their assigned car, but it is difficult for customers assigned to the second or third car to determine which car to ride on among the cars whose hall lanterns are lighting
Solution Approach 1:
The patent applies local quality by providing differentiated information channels: disabled persons receive hall lantern guidance for their assigned car, while other passengers rely on the display unit showing car numbers. This selective guidance approach ensures that each group receives appropriate information without confusion from multiple lighting signals.

AI summary
In an elevator system 1000, an elevator-hall-call/destination-floor-call registration devices 100A and 100B provided at an elevator hall include, besides a destination floor registration button 101 such as a numeric keypad, etc. formed by buttons having respective numbers of 0 to 9 for registering a destination floor, a disabled person button 102 declaring that a customer is a disabled person. For example, in the elevator-hall-call/destination-floor-call registration device 100A, when the disabled person button 102 is pressed and as well the destination floor call is inputted, a group management control device 300 registers the destination floor call, and as well determines a car to be assigned for the destination floor call, rings a chime and further turns on a hall lantern corresponding to the determined assigned car. Like the above, the group management control device 300 rings the chime and turns on the hall lantern only when the disabled person button 102 is pressed.
