Elevator Group Reassignment for Real-Time Traffic Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems often fail to dynamically adjust elevator car assignments based on real-time traffic patterns and passenger demand, leading to inefficiencies in passenger wait times and system utilization.
Innovation Solution
Implementing a control system that uses machine learning to monitor elevator usage patterns and dynamically reassign elevator cars among sectors in response to traffic demands, allowing for real-time adjustments based on passenger counts and call frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elevator cars are organized into fixed groups serving specific sectors, then system organization and control simplicity are improved, but adaptability to changing traffic patterns and passenger wait time are worsened
Solution Approach 1:
The patent implements dynamic reassignment of elevator cars between sectors based on real-time traffic demand. Instead of fixed sector assignments, the system continuously monitors usage patterns and automatically redistributes elevator resources, allowing the same physical infrastructure to adapt to varying traffic conditions throughout the day
Solution Approach 2:
The system incorporates continuous monitoring of elevator usage patterns and traffic demand, using this feedback information to trigger automated reassignment decisions. The feedback loop enables the system to respond to changing conditions by detecting usage patterns and initiating reallocation when thresholds are exceeded
2Stability of the object's composition
If sectors remain unchanged in the elevator system, then system stability and control simplicity are improved, but passenger wait time and system efficiency are worsened during peak demand
Solution Approach 1:
The system maintains stable sector definitions but dynamically adjusts which elevator cars serve which sectors based on real-time demand. This allows the logical organization to remain stable while the physical resource allocation becomes flexible, reducing wait times during peak periods without disrupting overall system structure
Solution Approach 2:
The patent changes the operational parameters of elevator car assignments rather than altering the physical sectors themselves. By modifying assignment parameters dynamically while keeping sector boundaries fixed, the system reduces passenger wait time without compromising structural stability
3Ease of operation
If elevator groups serve different zones statically, then system organization is improved, but productivity and system utilization are worsened when traffic patterns change
Solution Approach 1:
Elevator cars are designed to serve multiple sectors throughout the day rather than being dedicated to a single sector. The same elevator car can be assigned to different service groups at different times, making the fleet universally capable of serving any sector and maximizing overall system utilization
Solution Approach 2:
The system dynamically reassigns elevator cars between service groups based on real-time traffic demand. When a sector experiences peak usage, additional elevator cars are automatically allocated to that sector, optimizing productivity without requiring permanent reconfiguration of service groups

AI summary
A method of operating a building elevator system within a building having a plurality of floors is provided. The method including: controlling a first elevator group composed of one or more elevator systems configured to serve a plurality of floors within a first sector, the one or more elevator systems in the first elevator group further include a first elevator car; controlling a second elevator group composed of one or more elevator systems configured to serve a plurality of floors within a second sector, the one or more elevator systems in the second elevator group further include a second elevator car; monitoring usage of the first elevator group and second elevator group; and reassigning at least one of the one or more elevator systems of the second elevator group to the first elevator group in response to usage of the first elevator group and usage of the second elevator group.
