Elevator Destination Call Division for High-Rise Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large high-rise buildings, passengers face inefficiencies in navigating and optimizing elevator usage due to complex algorithms required for multiple elevator groups, leading to uncertainty in choosing the correct elevator group and inefficient capacity utilization.
Innovation Solution
A method for dividing destination calls between elevator groups using shared floors and destination call appliances connected to group controls, employing defined division criteria to allocate calls based on traffic situations and passenger information, allowing for dynamic adjustment of criteria to optimize traffic and service targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple elevator groups are used to serve large high-rise buildings, then the transport capacity is increased, but the complexity of call allocation and passenger navigation increases
Solution Approach 1:
The patent divides the large elevator system into multiple independent elevator groups, each managed by its own group control. This segmentation allows each control unit to handle a smaller subset of calls independently, reducing the computational complexity for each controller while maintaining overall system capacity through the combined effort of multiple groups.
2Productivity
If a single group control manages all elevator groups, then optimal call allocation can be achieved, but the control system becomes complicated and expensive
Solution Approach 1:
The patent segments the centralized control function into distributed group controls, where each elevator group has its own control unit. This distributed architecture maintains allocation efficiency within each group while avoiding the complexity and cost of a single centralized controller managing all groups.
Solution Approach 2:
The patent introduces a call division mechanism that acts as an intermediary between the passenger and the elevator groups. This intermediary divides incoming calls according to predefined criteria and routes them to appropriate elevator groups, enabling efficient resource distribution without requiring complex inter-group coordination.
3Quantity of substance
If passengers must choose the correct elevator group, then the transport capacity is optimized, but the ease of operation deteriorates due to passenger uncertainty
Solution Approach 1:
The patent implements self-service by automatically dividing calls between elevator groups based on predefined criteria without requiring passenger intervention. The system autonomously determines which elevator group should serve each call, eliminating the need for passengers to navigate complex group selections while maintaining optimized transport capacity utilization.
4Power
If call division between elevator groups is implemented, then the computing capacity is distributed efficiently, but the system requires complex division criteria and coordination
Solution Approach 1:
The patent utilizes parameter changes in call division criteria, dynamically adjusting division rules based on system state. This allows the system to distribute computing capacity effectively while managing complexity through adaptive parameter adjustment rather than rigid complex rules.

AI summary
The present invention discloses a method and a system for dividing destination calls in an elevator system, which comprises at least two elevator groups, which elevator groups have one or more shared floors and also destination call appliances on at least the aforementioned shared floors for receiving destination calls given by passengers. The destination call appliances are connected to the group controls of the elevator groups, and the destination calls given by passengers are divided between the elevator groups on the basis of the defined division criteria.
