Elevator Arrival Time Display System for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems generate background noise and require passengers to constantly concentrate on loudspeaker announcements, making it unpleasant and hectic, especially during peak times, and fail to provide continuous or interval updates on traffic volume changes.
Innovation Solution
Implementing a device with first and second information displays at the start floor and in the elevator car to show estimated and actual arrival times, along with traffic volume updates, using digital or analog displays that can be integrated into existing panels or mounted separately, allowing passengers to focus on changing information without background noise and providing enhanced safety through identification/authentication features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If loudspeaker announcements are used to inform passengers about elevator arrival times and traffic status, then passengers receive information about car arrival and occupancy, but background noise increases and passengers experience stress and fatigue during peak times
Solution Approach 1:
The patent replaces the acoustic information delivery system (loudspeakers) with a visual information display system (electronic displays at floors and in cars). This substitution eliminates background noise while maintaining effective communication of arrival times and traffic status to passengers.
Solution Approach 2:
The patent introduces visual displays as an intermediary between the elevator control system and passengers. These displays convey information about arrival times and traffic conditions without requiring acoustic communication, thereby resolving the conflict between information delivery and noise reduction.
2Loss of information
If loudspeaker announcements are made frequently to keep passengers updated on traffic volume, then passengers receive continuous information about elevator status, but passengers must constantly concentrate to hear announcements which is wearisome
Solution Approach 1:
The patent replaces the acoustic announcement system with visual displays that continuously show traffic status and arrival times. This allows passengers to obtain information at their own pace without the need for constant concentration, eliminating the wearisome effect while maintaining continuous information delivery.
3Loss of time
If estimated arrival time is provided immediately to passengers, then passengers receive prompt acknowledgment of their call, but the information may change before actual arrival requiring updates
Solution Approach 1:
The patent provides an estimated arrival time immediately upon passenger call as a preliminary indication, then updates this information with the actual arrival time when available. This approach gives passengers prompt acknowledgment while ensuring they receive accurate, up-to-date information throughout the waiting period.
Solution Approach 2:
The system implements feedback by continuously updating the displayed arrival time information from estimated to actual values. This feedback mechanism ensures passengers receive accurate information while maintaining prompt initial response to their calls.

AI summary
A device and a method for informing passengers of an elevator installation in a building includes at least one information display at at least one start floor and/or at least one second information display in at least one car. The first information display indicates the arrival time of a car at a start or destination floor and the second information display indicates the arrival time of the car at a destination floor.
