Elevator Destination Call Controller for Zero Floor Difference Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems face inefficiencies in passenger transportation due to the need for passengers to use stairs or moving staircases when the destination floor differs from the call input floor, especially during varying traffic volumes and times, which can lead to suboptimal journeys and increased service costs.
Innovation Solution
Implementing a destination call controller that checks situation-specific parameters such as traffic volume and passenger benefits to allocate elevator cabin journeys with zero floor difference when possible, and optimizes call allocations with minimal detours or changes when not, using both fixed and mobile input devices for flexible destination call input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a destination call is allocated to an elevator cabin departing from a floor different from the call input floor, then the transportation capacity of the elevator system is increased, but the passenger convenience deteriorates due to the need to use stairs or moving staircases
Solution Approach 1:
The system dynamically changes the allocation parameters based on traffic volume and time of day. During peak hours, it accepts floor differences to maximize transportation capacity, while during off-peak hours, it prioritizes zero floor difference allocations to maintain passenger convenience. This parameter-based dynamic adjustment resolves the contradiction between productivity and ease of operation.
Solution Approach 2:
The elevator control system transitions from static allocation rules to dynamic allocation that adapts to changing traffic conditions. The system continuously monitors traffic volume and adjusts allocation strategies in real-time, allowing the same system to serve different operational modes (high capacity vs. high convenience) based on current conditions.
2Speed
If immediate allocation of destination calls is implemented, then the service speed is improved, but the ability to optimize for passenger benefit deteriorates due to lack of traffic information
Solution Approach 1:
The system performs preliminary actions by collecting and analyzing traffic data before making allocation decisions. The destination call controller pre-processes traffic information and uses it to inform immediate allocation decisions, thereby maintaining fast service speed while incorporating optimization capabilities based on traffic patterns.
Solution Approach 2:
The system implements feedback mechanisms where traffic information is continuously monitored and fed back to the allocation algorithm. This feedback loop enables the system to adjust its immediate allocation decisions based on current traffic conditions, maintaining both speed and adaptability.
3Productivity
If double elevator cabins approach adjacent floors simultaneously, then the transportation capacity is increased, but the device complexity increases due to coordinated control requirements
Solution Approach 1:
The system merges the control of multiple elevator cabins under a single destination call controller that handles multiple shafts. By combining the allocation logic and traffic management functions into one integrated controller, the system achieves coordinated operation of double cabins without proportionally increasing control complexity.

AI summary
An elevator system having a double or multiple elevator cabins per elevator shaft can be controlled using a method, wherein at least one destination call is entered or at least one identification code is received on at least one call entry floor, said destination call or identification code designating an arrival floor; wherein at least one trip by at least one elevator cabin of the double or multiple elevator cabin from a departure floor to an arrival floor is determined for the destination call or identification code; wherein before determining a trip, it is determined whether at least one situation-specific parameter is fulfilled; and if said situation-specific parameter is fulfilled, at least one situation-compatible call assignment is determined for a trip having a floor difference of zero between the call entry floor and the departure floor or having a floor difference of zero between the destination floor and the arrival floor.
