Elevator Display Control for Information Redisplay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator information display devices often interrupt general information display for users not getting in or out at the service floor, leading to dissatisfaction due to omitted or incomprehensible information, and high scroll speeds impair readability when large amounts of information are displayed.
Innovation Solution
An elevator information display device that selectively prioritizes elevator information over general information based on operational state, using an information display control section to interrupt and redisplay general information as necessary, ensuring continuous and comprehensible information delivery to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general information is displayed continuously in elevator information display devices, then user satisfaction is improved by providing engaging content, but elevator information may be omitted or interrupted when operational updates are needed
Solution Approach 1:
The display device dynamically adjusts its behavior based on elevator operational state. When the elevator is stationary or in non-critical states, general information is displayed continuously. When movement or critical operations are detected, the system transitions to prioritize elevator information, ensuring both types of information are delivered appropriately based on real-time conditions
Solution Approach 2:
The system monitors elevator operational state continuously and uses this feedback to control information display priorities. The control unit receives feedback about elevator movement and operational status, then adjusts display content accordingly, ensuring that elevator information is never omitted while also maximizing general information delivery during appropriate time windows
2Loss of information
If scroll speed is increased to display all general information within elevator running time, then information delivery completeness is improved, but readability is impaired due to excessively fast scrolling
Solution Approach 1:
Instead of attempting to display all general information within the entire elevator running time, the system displays information for a predetermined appropriate time window. This partial action approach ensures that the most relevant general information is delivered without requiring excessively fast scroll speeds, maintaining readability while still providing engaging content during non-critical elevator states
Solution Approach 2:
The system changes the display parameter (scroll speed) based on the amount of information and time available. When information volume is large, scroll speed is adjusted to maintain readability. The control unit dynamically adjusts display parameters to balance information delivery completeness with user comfort and readability
3Ease of operation
If scroll display is stopped temporarily during user entry and exit, then users can read information uninterruptedly, but users who remain in the hall experience unexpected interruption and dissatisfaction
Solution Approach 1:
The system applies different display behaviors to different user groups based on their location. When users are detected in the car, the display pauses to allow reading. When users are in the hall, general information continues to scroll. This localized quality approach ensures that each user group receives the appropriate display treatment for their situation
Solution Approach 2:
The display system dynamically adjusts its behavior based on real-time detection of user location and elevator operational state. Rather than using a fixed stop-and-go scroll pattern, the system continuously adapts display behavior to current conditions, ensuring both car users can read information and hall users experience continuous information delivery

AI summary
An elevator information display device including: an information display control section that selects, based on an elevator state, information to be displayed from elevator information and general information, interrupts, when a predetermined display interruption factor occurs during display of general information, display of the general information concerned, and displays the elevator information; a display state administration section that determines whether or not the general information has finished being displayed to the end of the information display unit; and a redisplay determination section that determines, when the display of general information has been interrupted, based on the display interruption factor relating to the interruption and the result of the determination, whether or not the redisplay of the interrupted general information is necessary, wherein the information display control section redisplays the general information, which has been determined to be necessary to be redisplayed, from the beginning of the information display unit.
