Elevator Control Device Hall Destination Floor Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator control devices fail to address scenarios where a user cannot ride on their assigned elevator car due to reasons like missing the car, full-load, or car failure, and do not consider the moving time and distance from the security gate to the elevator hall for optimal operation.
Innovation Solution
An elevator control device with a hall destination floor registration device that allows users to register their destination floor and validates registrations based on conditions such as the assigned car's arrival status and load, enabling alternative elevator usage and optimizing operation control based on moving time and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system assigns a specific elevator car to each user based on destination floor information, then elevator operation efficiency is improved, but user convenience deteriorates when the user cannot ride on the assigned car
Solution Approach 1:
The system dynamically adjusts the rigidity of destination call registration based on real-time conditions. When the assigned car is unavailable (full-load, failure, or user misses it), the system transitions from a fixed assignment mode to a flexible registration mode, allowing users to register destination calls in the hall. This dynamic adaptability resolves the contradiction by maintaining efficiency through automatic assignment while preserving convenience through fallback registration capabilities.
Solution Approach 2:
The system changes the parameter of destination call registration status from fixed to variable. By introducing validation conditions that can switch between valid and invalid states based on car availability and user action timing, the system allows flexible registration when needed while maintaining automatic assignment efficiency during normal operation. This parameter change enables the system to adapt between efficiency and convenience requirements.
2Speed
If the system automatically registers destination calls based on pre-registered destination floor information, then processing speed is improved, but adaptability to unexpected situations deteriorates
Solution Approach 1:
The system prepares multiple operational pathways in advance: automatic destination call registration for normal cases, and manual hall destination floor registration for exception cases. By pre-configuring these alternative registration methods and their validation conditions, the system ensures smooth transitions when automatic registration fails, maintaining both speed and adaptability without requiring real-time complex decision-making.
3Speed
If the security gate opens immediately upon authentication, then entry speed is improved, but control over user flow deteriorates
Solution Approach 1:
The system performs preliminary authentication and gate opening actions quickly upon user presentation of credentials, maintaining fast entry speed. Simultaneously, it pre-registers the user's destination floor information and prepares the assigned car allocation before the user reaches the hall. This preliminary preparation allows the system to maintain both rapid entry and effective flow control through pre-coordinated elevator dispatch.

AI summary
In an elevator control device in which, when a verified person is authenticated as a registered person by an person authentication device, a security gate is opened to enable the movement into an elevator hall, even when a user cannot ride on an assigned car for some reason after passing through the security gate, the user is enabled to use an elevator, and convenience can be prevented from becoming poor. For this purpose, a hall destination floor registration device is provided in the elevator hall so that the user who is present in the hall registers his/her destination floor. A destination call is always registered automatically interlocking with the security gate, and when a predetermined condition is met, the destination floor registration of user made using the hall destination floor registration device is validated.
