Elevator Car Assignment Confirmation Using Personal ID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems fail to provide sufficient guidance on assigned elevator cars after destination calls are registered, leading to user confusion and potential misboarding, especially when personal information is used for special operations.
Innovation Solution
An elevator system that requires users to input personal information before boarding, using ID recognition and assigned car notification systems to ensure accurate and continuous car assignment information is provided through dedicated devices or a combined device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an indication device shows the assigned elevator number only temporarily, then the system complexity is reduced, but the user cannot confirm the assigned elevator after leaving the registration area
Solution Approach 1:
The patent introduces a portable terminal (smartphone, tablet, or wearable device) as an intermediary between the indication device and the user. The terminal receives the assigned elevator number from the indication device via short-range wireless communication and stores it locally, allowing the user to access the information at any time after leaving the registration area.
Solution Approach 2:
The patent transitions the information display from a fixed spatial dimension (indication device at registration location) to a portable temporal dimension (terminal device that moves with the user). This allows the user to carry the assigned elevator information anywhere in the building.
2Device complexity
If only destination floor information is displayed on the indication device, then the device complexity is reduced, but users may board the wrong elevator especially when special operations are involved
Solution Approach 1:
The patent segments the information display into two distinct parts: destination floor information and assigned elevator number. This segmentation allows users to clearly distinguish between the destination they requested and the specific elevator assigned to serve them, preventing confusion and ensuring accurate boarding.
3Reliability
If the registration device is installed away from the elevator hall for security reasons, then security is improved, but users may forget the assigned elevator number during movement to the hall
Solution Approach 1:
The portable terminal serves as a portable memory intermediary that travels with the user from the registration location to the elevator hall. This eliminates the problem of forgetting the assigned elevator number during movement, while the registration device can remain securely installed away from the elevator hall.

AI summary
In an elevator system in which a user registers a destination call by inputting his or her personal information before boarding an elevator car, it is ensured that information on an assigned car can be appropriately provided, and that the user is able to easily make sure of the elevator car to board even after the registration of a destination call. For this purpose, there is installed in an elevator hall or the like a destination call registration device with which a user registers a destination call before boarding the elevator car and which has an assigned car confirmation means with which a user makes sure of an assigned car by inputting his or her personal information. When an elevator has been assigned to a destination call registered from the destination call registration device, regarding the destination call for which the assignment has been performed, information on an assigned car and personal information of a user are stored in storage means by associating these pieces of information with each other. When personal information of a user has been inputted, the assigned car confirmation means provides information on the assigned car of the user on the basis of the personal information and the memory content in the storage means.
