Elevator Car Panel Display Based on Travel Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator display panels face challenges in displaying all floors conveniently, especially in tall buildings, leading to increased operation time and complexity for passengers to locate their desired floor.
Innovation Solution
An elevator operation panel that displays first floor information based on the elevator's movement trend, with adjustable display settings via a touch control area, allowing for differentiated display effects and the option to unfold additional information upon input, using a liquid crystal display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the elevator display panel displays all floors, then complete floor information is provided, but the display identifier for each floor becomes extremely small and passengers cannot quickly locate the desired floor
Solution Approach 1:
The floor information is segmented into two categories: floors on the movement trend (first floor information) and floors not on the movement trend (second floor information). This segmentation allows the panel to display only relevant floors prominently, making floor location faster while still providing access to complete information through the unfolding mechanism.
Solution Approach 2:
The display panel dynamically adjusts its content based on the elevator's movement trend. When the elevator is moving upward, only upward floors are displayed; when downward, only downward floors are displayed. This dynamic adaptation reduces the number of displayed floors from all floors to just the relevant direction, solving the contradiction between information completeness and location speed.
2Loss of information
If the display panel shows all floors with small identifiers, then all floor information is available, but operation complexity increases and passengers take extra time to locate desired floor
Solution Approach 1:
The system performs preliminary action by pre-filtering and displaying only the floors that are relevant to the current elevator movement direction. This preliminary selection eliminates the need for passengers to search through all floors, reducing floor selection time while maintaining information availability through the unfolding function.
Solution Approach 2:
Different display qualities are applied to different floor information. Floors on the movement trend are displayed with large, prominent identifiers for quick location, while floors not on the movement trend are either hidden or displayed with smaller identifiers. This local quality differentiation optimizes both information availability and selection speed.
3Loss of information
If the panel displays all floors, then complete information is shown, but the display size for each floor identifier is limited to very small space
Solution Approach 1:
Floor information is segmented into first floor information (on movement trend) and second floor information (not on movement trend). This segmentation allows the panel to allocate sufficient display space to relevant floors, ensuring large, visible identifiers for floors on the movement trend while managing the overall information presentation.
Solution Approach 2:
The display dynamically adjusts which floors receive prominent display space based on the elevator's movement direction. When moving upward, upward floors receive full display space with large identifiers; when moving downward, downward floors receive the space. This dynamic space allocation ensures adequate identifier size for relevant floors while maintaining information completeness through selective display.

AI summary
An elevator operation panel, an elevator system and an elevator panel display method. The elevator operation panel includes: a display area configured to display first floor information of the building based at least on an elevator movement trend, wherein the first floor information includes all floors that the elevator has not yet arrived at on the elevator movement trend; a touch control area configured to receive an input instruction; and a control unit configured to receive an input instruction from the touch control area, and adjust display information of the display area according to the input instruction, wherein the control unit is further configured to receive the floor change information of the building, and adjust the display information of the display area according to the floor change information of the building.
