Elevator Assigned Car Display Device for Personalized Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator systems face issues with user confusion and security breaches due to the display of assigned elevator car information at security gates, language support limitations, and inadequate handling of abnormal conditions, leading to inefficiencies and security concerns.
Innovation Solution
An assigned car information display apparatus that dynamically adjusts display attributes such as language, font, graphics, and color based on user attributes, provides audio information, and offers clear instructions in multiple languages during abnormal conditions, ensuring user-specific and secure display of elevator car assignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the assigned elevator car is displayed at the security gate, then users can identify their assigned car, but users may become confused when multiple users pass through continuously as the same car information is displayed for different users
Solution Approach 1:
The display information is segmented into multiple components: assigned car number, user ID, and destination floor. Each component is displayed separately with distinct visual characteristics, allowing users to quickly identify their specific information while preventing confusion with other users' information.
Solution Approach 2:
Different visual qualities are applied to different parts of the display. The user ID and destination floor are displayed with different font styles, sizes, or colors compared to the assigned car number. This local differentiation helps users quickly locate and verify their specific information among the displayed elements.
2Loss of information
If the destination floor is displayed together with the assigned elevator car, then users can confirm their destination, but user's destination floor is disclosed to different users which is undesirable from security viewpoint
Solution Approach 1:
The destination floor information is extracted and displayed separately from the assigned car number in a different location or with different visual characteristics. This separation allows users to confirm their destination while making it less obvious to other users, balancing information accessibility with security concerns.
Solution Approach 2:
The information is displayed in multiple dimensions or layers. The assigned car number may be displayed prominently in one dimension while the destination floor is displayed in another dimension (different location, size, or visual style), allowing users to access both pieces of information while reducing the risk of unauthorized observation.
3Productivity
If the display content is renewed sequentially for each user, then each user receives their assigned car information, but the system cannot support multiple languages appropriately when users pass through one by one
Solution Approach 1:
The display system is designed with multi-functionality to support multiple languages simultaneously. The control unit can detect the user's language preference and automatically switch display languages without requiring separate display devices or manual intervention, enabling the system to serve diverse linguistic groups efficiently.
Solution Approach 2:
The display system dynamically adapts to each user's language preferences in real-time. When a user approaches the gate, the system detects their language setting and adjusts the display content accordingly, allowing seamless multi-language support while maintaining sequential processing efficiency.
4Object-affected harmful factors
If only the assigned car number is displayed without destination floor, then security is maintained, but users cannot distinguish whether the information is for themselves or previous users when the same car is assigned to multiple users
Solution Approach 1:
The display information is segmented into multiple components: assigned car number, user ID, and destination floor. Each component is displayed separately with distinct visual characteristics, allowing users to quickly identify their specific information while preventing confusion with other users' information.
Solution Approach 2:
Different visual qualities are applied to different parts of the display. The user ID and destination floor are displayed with different font styles, sizes, or colors compared to the assigned car number. This local differentiation helps users quickly locate and verify their specific information among the displayed elements.

AI summary
An assigned car information display apparatus for elevators is provided which is capable of providing a suitable display for a user by changing a representation method (such as a displayed graphic figure and color) of one and the same assigned car based on elevator user's attributes (such as a working department name, and personal preferences) even when the one and the same car is assigned to plural different destination floors. An assigned car information display device displays assigned car information for a specific user by changing, based on an attribute of a user, an attribute of the display screen when the assigned elevator car is displayed.
