Elevator Call Controller Dynamic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator installations face inefficiencies in managing traffic demand, leading to suboptimal passenger movement and increased energy consumption during varying traffic conditions, as existing systems lack effective mechanisms for dynamic allocation of elevators and real-time traffic information dissemination.
Innovation Solution
Implementing a method for an elevator installation that includes a call controller and sensors to dynamically switch between normal and busy-period modes based on traffic thresholds, allocating elevators to main operation landings and providing passengers with real-time traffic information through visual and auditory signals, utilizing various sensors for passenger detection and load estimation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the elevator installation operates in normal mode with individual call allocation, then passenger service coverage is comprehensive, but system response time increases during peak traffic periods
Solution Approach 1:
The elevator system dynamically switches between normal operation mode and busy-period mode based on real-time traffic detection. During peak periods, the system automatically transitions to express operation mode with predefined main operation landings, optimizing response time for high-demand areas while maintaining comprehensive service coverage through selective elevator allocation.
Solution Approach 2:
The system changes operational parameters by switching between different operation modes (normal vs. busy-period). In busy-period mode, the call controller allocates elevators to specific main operation landings based on traffic thresholds, changing the service distribution parameters to prioritize high-demand areas and reduce response time.
2Loss of energy
If elevators serve all landings individually, then service accessibility is maximized, but energy consumption increases during peak periods
Solution Approach 1:
During busy periods, the system extracts or removes individual call allocation for non-main landings from the elevator service. Elevators are allocated exclusively to predefined main operation landings with high traffic demand, eliminating unnecessary trips to lower-demand landings and significantly reducing energy consumption while maintaining accessibility for critical areas.
Solution Approach 2:
The system segments elevator service into dedicated main operation landings versus other landings. By dividing the service area and allocating specific elevators to specific landing groups, the system optimizes energy efficiency for high-demand areas while maintaining service accessibility where needed, rather than serving all landings uniformly.
3Productivity
If the system implements dynamic mode switching and traffic monitoring, then operational efficiency improves, but system complexity increases
Solution Approach 1:
The call controller automatically detects traffic conditions and switches operation modes without manual intervention. The system self-regulates by monitoring traffic thresholds and autonomously allocating elevators to main operation landings, improving operational efficiency while minimizing the complexity of manual control and system management.
Solution Approach 2:
The system incorporates traffic detection and monitoring mechanisms that provide feedback to the call controller. Based on real-time traffic information, the system adjusts elevator allocation and operation mode automatically, improving operational efficiency through closed-loop control while keeping the complexity manageable through automated decision-making algorithms.

AI summary
An elevator system includes at least one elevator, at least one call input device and a call controller. The call input device transmits a call to the call controller. For a transmitted normal operation signal, at least one elevator car of an assigned elevator is activated to drive to the call input floor by at least one elevator controller of the assigned elevator. In a peak-time mode of the elevator system, at least one main operation signal is transmitted to at least one elevator. For a main operation signal transmitted to an elevator, at least one elevator car of said elevator is activated to drive between at least two main operation floors by at least one elevator controller of said elevator.
