Elevator Group Control Device for Mixed User Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems face challenges in efficiently managing elevator allocations for users without information communication terminals, leading to inadequate service provision in mixed user environments.
Innovation Solution
A group management control device allocates elevator calls based on user information obtained from various devices, including ID cards and smartphones, using a system that immediately decides allocations for non-smartphone users and delays decision-making for smartphone users until after a predetermined time, ensuring efficient elevator allocation and user notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the system immediately decides elevator allocation for all users, then response speed is improved, but service quality for smartphone users deteriorates due to premature allocation before user information is fully obtained
Solution Approach 1:
The patent segments users into two categories: those with information communication terminals (smartphones) and those without (using ID cards). Different allocation strategies are applied to each segment. For smartphone users, allocation is delayed until after a predetermined time to ensure complete information acquisition. For ID card users, immediate allocation is applied. This segmentation resolves the contradiction by allowing immediate response for some users while maintaining service quality for others.
Solution Approach 2:
The patent implements dynamic allocation decision-making based on user type. The controller adjusts its behavior dynamically: for smartphone users, it waits for a predetermined time period to ensure complete information acquisition before allocating. For ID card users, it immediately decides allocation. This dynamic approach allows the system to optimize both response speed and service quality by adapting to different user scenarios.
2Reliability
If the system delays allocation decision for smartphone users, then service quality is improved by ensuring complete information acquisition, but response time deteriorates
Solution Approach 1:
The patent segments users into two categories with different allocation strategies. Smartphone users experience delayed allocation (improving service quality through complete information acquisition) while ID card users experience immediate allocation (minimizing response time). This segmentation allows the system to accept longer response times for smartphone users while maintaining fast response for ID card users, overall resolving the time loss issue.
Solution Approach 2:
The patent changes the allocation decision parameter based on user type. For smartphone users, the controller waits for a predetermined time period before allocating. For ID card users, immediate allocation occurs. This parameter change (waiting time vs. immediate decision) allows the system to optimize service quality for smartphone users while minimizing time loss for ID card users.
3Ease of operation
If the system provides immediate allocation notification to all users, then user satisfaction is improved, but system complexity increases due to multiple notification channels
Solution Approach 1:
The patent segments notification delivery by user type. For smartphone users, allocation information is transmitted via radio communication to the smartphone. For ID card users, notification is provided through the card reader display. This segmentation allows the system to provide satisfied users with appropriate notifications while managing complexity by using established communication channels for each user segment rather than implementing a unified complex notification system.
Solution Approach 2:
The patent uses existing communication intermediaries for notification delivery. Smartphones serve as intermediaries for smartphone users, and card reader displays serve as intermediaries for ID card users. This approach avoids the need for a complex custom notification system by leveraging existing devices and communication protocols already present in the elevator system.

AI summary
When the received allocation request information indicates that the user information is obtained from the information communication terminal, the controller makes the storage unit store the allocation request information, and after elapse of a predetermined time from the reception of the allocation request information, reads the allocation request information to decide the allocation elevator to which the call relating to the allocation request information is to be allocated, and transmits information indicating the decided allocation elevator to the information communication terminal via a predetermined radio communication device.
