Three-Sided Elevator Guide Display for Lobby Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for notifying users in an elevator lobby of an elevator's operation state are insufficient in clearly presenting the sequence of operation states, including selecting the car, door opening, and closing, as they require checking multiple devices and do not effectively convey the relative position and arrival direction of the elevator car.
Innovation Solution
A guiding device that uses a three-sided frame to display guidance information through lights, indicating the selected car's position, arrival direction, and door states, utilizing operation and door information from a car moving device to provide intuitive visual cues about the elevator's sequence of operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple conventional notification devices (up/down buttons, indicators, hall lanterns, sound, voice guidance) are used to display elevator operation states, then the information coverage is comprehensive, but the user must check each device separately and the information is not integrated enough to clearly present the sequence of operation states
Solution Approach 1:
The patent combines multiple notification functions (car selection indication, movement direction, position, arrival status, door state) into a single integrated display device. This display device presents all operation states in a unified visual interface, eliminating the need for users to check multiple separate devices while maintaining comprehensive information coverage.
Solution Approach 2:
The display device serves multiple functions simultaneously: it indicates car selection, displays movement direction, shows car position, notifies arrival status, and indicates door states. This multi-functional display consolidates what previously required multiple specialized notification devices into one universal interface.
2Loss of information
If conventional notification devices are used, then various operation states can be notified, but the relative position and arrival direction of the elevator car cannot be effectively conveyed
Solution Approach 1:
The display device uses different colors to represent different operation states and directions. For example, upward movement may be indicated by one color while downward movement uses another, and car selection is highlighted with specific coloring. This visual coding makes position and direction information immediately recognizable and intuitive.
Solution Approach 2:
The display presents elevation information in a visual dimension rather than requiring users to infer it from separate auditory or textual notifications. The display shows the car's vertical position and movement direction as visual elements, making spatial information immediately perceivable.
3Ease of operation
If a three-sided frame display is used to show all operation states, then the information is integrated and easy to understand, but the device complexity increases compared to conventional separate notification devices
Solution Approach 1:
The display device is divided into multiple independent display regions, each responsible for showing a specific operation state (car selection region, movement direction region, position region, arrival region, door state region). This segmentation allows the complex information to be organized into manageable visual modules while maintaining overall integration.

AI summary
A guiding device according to the present invention generates and displays guidance information for displaying a sequence of operation states of an elevator on a three-sided frame corresponding to the car responding to a call for the elevator or the periphery of the three-sided frame. The sequence of operation state of the elevator includes the position of the lobby corresponding to the car number of the car selected from among a plurality of cars in response to the call for the elevator, the movement of the car of the elevator, the arrival direction of the car, a situation where the car arrives at the calling floor and the door opens, a situation where the door is fully open and starts closing, and a situation where the door is closing. Thus, a user in the lobby can intuitively determine the complicated sequence of operation states of the elevator.
