Ropeless Elevator Transfer System with Redundant Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ropeless elevator systems lack redundancy in transfer station operation, leading to reduced efficiency and potential operation delays due to the limited number of structures capable of moving elevator cars between lanes, especially in high-rise buildings where multiple cars need to travel in a single lane.
Innovation Solution
A ropeless elevator system with a transfer system that includes selectively deployable conveyors and transfer assemblies allowing elevator cars to move horizontally between lanes, enabling efficient transfer without interrupting the continuity of guide structures and allowing multiple cars to share lanes, thereby increasing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple elevator cars travel in a single lane using ropeless systems, then system efficiency and car capacity increase, but transfer station redundancy decreases and operation delays occur
Solution Approach 1:
The transfer station is divided into multiple independent transfer assemblies (first transfer assembly and second transfer assembly), each capable of independently transferring elevator cars between lanes. This segmentation provides redundancy so that if one transfer assembly fails, the other can still operate, maintaining system reliability while supporting multiple cars per lane
Solution Approach 2:
The transfer assemblies are designed with movable and adjustable components that can dynamically adapt to different operational requirements. The system can flexibly configure which transfer assembly is active based on real-time conditions, optimizing efficiency while maintaining redundancy capabilities
2Stability of the object's composition
If transfer stations use fixed structures for moving elevator cars, then structural stability is maintained, but system flexibility and adaptability decrease
Solution Approach 1:
The transfer station incorporates movable transfer assemblies that can be positioned and configured dynamically. These assemblies include adjustable components that can adapt to different car positions and transfer requirements, providing both structural stability during operation and flexibility in configuration
Solution Approach 2:
The transfer assemblies are designed to perform multiple functions: transferring cars between lanes, providing redundancy backup, and adapting to different operational modes. This multi-functionality allows the same structural components to serve various purposes, enhancing both stability and adaptability
3Reliability
If independent transfer structures are used for each lane, then transfer reliability is improved, but device complexity and space requirements increase
Solution Approach 1:
Multiple transfer assemblies are combined within a single integrated transfer station structure. The first and second transfer assemblies share common structural elements, control systems, and spatial infrastructure, reducing overall complexity while maintaining independent operational capability and reliability of each transfer path

AI summary
A ropeless elevator system includes a first lane, a second lane disposed adjacent to the first lane, and an elevator car moveable within each of the first lane and the second lane. A transfer system is configured to facilitate movement of the elevator car from one of the first lane and the second lane to the other of the first lane and the second lane. The transfer system includes a first transfer assembly arranged in at least one of the first and second lanes. The first transfer assembly is configured to guide the elevator car out of the one of the first and second lanes. A transfer station includes a second transfer assembly configured to receive the elevator car from the first transfer assembly. The second transfer assembly extends between the first and second lanes.
