Elevator Destination Floor Indicator with Dynamic Layout Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional car destination floor indication devices face challenges in high-rise buildings with numerous floors, including limited installation space, high installation costs, and difficulties in displaying all registered destination floors due to the need for numerous buttons or a small screen with fixed-size indication, which can lead to flickering and unclear user understanding of registration changes.
Innovation Solution
A car destination floor indication device with an indication section and an indication control section that switches between multiple layouts based on the number of registered floors, allowing all floors to be displayed even when numerous floors are registered, ensuring users can easily grasp registration changes without frequent screen flickering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a destination floor registration button is provided for each destination floor, then the destination floor indication is clear and simple, but a large installation space is required and installation costs increase
Solution Approach 1:
The patent combines the destination floor registration function and destination floor indication function into a single integrated device. The same button panel serves both to register destination floors and to display which floors are registered, eliminating the need for separate indication devices and reducing installation space.
Solution Approach 2:
The button panel performs multiple functions: it serves as both the registration interface for destination floors and the indication display for registered floors. Each button can be pressed to register a destination floor and simultaneously lights up to indicate that floor is registered, making the system multi-functional and space-efficient.
2Area of stationary object
If a numerical key type destination floor registration device is used, then the installation space is reduced, but the registration buttons cannot serve for destination floor indication and a separate indication device is required
Solution Approach 1:
The patent merges the numerical key input system with the indication display system into a single integrated button panel. The same buttons used for numerical input also serve as indication elements, eliminating the need for separate indication devices and reducing overall system complexity.
Solution Approach 2:
The button panel is designed to perform dual functions: numerical key input for destination floor registration and visual indication of registered floors. This multi-functionality reduces the need for additional components and simplifies the overall device structure.
3Area of stationary object
If a small screen with fixed-size indication is used to display destination floors, then the installation space is reduced, but the display may flicker and user understanding of registration changes becomes difficult
Solution Approach 1:
The patent divides the indication display into multiple independent button elements rather than using a single small screen. Each button can independently light up to indicate a registered destination floor, allowing multiple floors to be displayed simultaneously without flickering and making it easy for users to understand registration changes.
Solution Approach 2:
The button panel dynamically adjusts its indication state based on registration changes. When a destination floor is registered, the corresponding button lights up; when cancelled, it turns off. This dynamic visual feedback provides stable and clear indication without the flickering problems associated with small fixed screens.

AI summary
There is provided a car destination floor indication device which can indicate all registered destination floors even when a large number of destination floors have been registered, and enables a user to easily grasp how the registration condition of destination floors has changed. For this purpose, a car destination floor indication device which is provided in a hall or car of an elevator and indicates destination floors of the elevator to users includes an indication section which indicates registered destination floors, and an indication control section which controls indication contents of the indication section and controls switching of a plurality of indication layouts for indicating the indication contents. The configuration is such that the indication control section performs switching of the indication layout presently being indicated to another indication layout belonging to the indication layouts when the number of registered destination floors has exceeded a first reference value and when the number of registered destination floors has become not more than a second reference value.
