Elevator Call Detecting Unit for Modernization Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator modernization often results in temporary reductions in transport capacity, leading to inconvenient waiting times and transfers for users, as existing systems struggle to maintain capacity during component exchanges.
Innovation Solution
Implementing a method where new floor terminals are introduced to communicate floor calls directly with a call detecting unit, which then communicates with both the existing and new group controls, allowing for adaptive traffic management and distribution of calls based on performance capabilities, thereby minimizing the need for multiple inputs and maintaining transport capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elevator is exchanged during modernization, then the transport capacity is temporarily reduced, but the system components are updated to newer technology
Solution Approach 1:
A call detecting unit is introduced as an intermediary component between the floor terminal and the group control. This unit can communicate with both the existing group control and the new group control simultaneously, enabling seamless transition during modernization without reducing transport capacity
Solution Approach 2:
The call detecting unit is pre-configured to communicate with both old and new group controls before the elevator exchange is completed. This preliminary setup ensures that call detection and routing functionality is maintained throughout the modernization process
2Adaptability or versatility
If a new floor terminal is introduced during modernization, then call routing capability is improved, but system complexity increases
Solution Approach 1:
The call detecting unit is designed with multi-functionality to communicate with both the existing group control and the new group control. This universal design allows a single component to handle multiple communication protocols and routing scenarios, improving adaptability without proportionally increasing complexity
3Productivity
If floor calls are distributed to multiple group controls, then transport capacity utilization is optimized, but control coordination complexity increases
Solution Approach 1:
The call detecting unit dynamically routes floor calls to either the existing group control or the new group control based on real-time system state and performance capabilities. This dynamic routing optimization maximizes transport capacity utilization while the unit itself manages the coordination complexity
