Elevator Lobby Assignment Control for Mixed-Use Building Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems in buildings often fail to adapt to changes in building use over time, leading to inefficiencies and the need for on-site technician intervention.
Innovation Solution
A building management system and elevator system integration that allows for dynamic assignment of elevators to elevator halls based on updated building information, enabling the elevator system to adjust its operation to changes in building use without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the elevator system remains unchanged after building use changes, then the original elevator configuration is maintained, but the elevator system cannot adapt to new building requirements
Solution Approach 1:
The elevator system implements dynamic configuration through software-based elevator hall assignments that can be modified without physical changes. The group controller dynamically adjusts elevator assignments to different halls based on building management system information, allowing the system to adapt to changing building uses while maintaining the same physical infrastructure.
Solution Approach 2:
The system changes operational parameters (elevator hall assignments, service patterns) rather than physical parameters. By modifying the building information in the storage unit and reconfiguring elevator assignments through software, the system adapts to new building requirements without altering the physical elevator infrastructure.
2Adaptability or versatility
If on-site technicians are used to adapt the elevator system to changes, then the elevator system can be reconfigured, but technician intervention increases complexity and cost
Solution Approach 1:
The elevator system performs self-reconfiguration through automated communication with the building management system. When building information changes are transmitted to the group controller, the system automatically updates its configuration and elevator assignments without requiring manual technician intervention, enabling the system to serve itself in adaptation scenarios.
Solution Approach 2:
The system establishes a feedback loop between the building management system and the elevator group controller. The building management system transmits updated building information to the elevator system, which then automatically adjusts its operation based on this feedback, creating a closed-loop adaptation mechanism that eliminates the need for manual reconfiguration.
3Reliability
If the elevator system is redesigned for new building use, then it fully meets new requirements, but the cost and time of system replacement increases
Solution Approach 1:
The system prepares for future building use changes by maintaining the capability to receive and process updated building information from the building management system. The group controller is pre-configured to accept building information changes and automatically adjust elevator assignments, allowing the system to rapidly adapt when building requirements change without requiring time-consuming redesign or replacement.

AI summary
The invention relates to a lift system (1) comprising a lift group with multiple lifts (E1-E6) and a group controller (12), which is designed to receive building information from a building management system (30). For a determined floor (L0) and for each lift (E1-E6), the received building information provides an assignment of each lift (E1-E6) to at least one lift lobby (H, H1-H9) from which the assigned lift (E1-E6) can be accessed on the determined floor (L0). Building information stored in a memory device (26) of the lift system (1) is updated by the received building information, wherein, for the determined floor (L0) and for each lift (E1-E6), the stored building information indicates an existing assignment of the respective lift (E1-E6) to at least one lift lobby (H, H1-H9). Upon receipt of a lift call, the lift system (1) is operated according to the updated building information. (Fig. 3)
