Elevator Cab 3D Routing via Rotatable Rail Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator systems are limited to two-dimensional transportability, which restricts the efficient use of available installation space and hinders complex travel movements within buildings.
Innovation Solution
The elevator system incorporates a multidimensionally rotatable rail segment that allows transfer between vertically, horizontally, and orthogonally oriented guide rails, enabling three-dimensional mobility of elevator cabs through rotatable rail segments and stator units, facilitating movement between different elevator shafts and allowing for versatile space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional two-dimensional elevator systems are used, then the system structure is simple, but the utilization of installation space is limited
Solution Approach 1:
The patent introduces a third dimension to the elevator system by adding guide rails and rotatable rail segments that enable movement not only vertically and horizontally but also in depth. This dimensional expansion allows cabs to access multiple shafts and destinations that were previously unreachable in a 2D plane, dramatically improving space utilization while accepting increased system complexity
Solution Approach 2:
The rotatable rail segments serve multiple functions: they act as transfer mechanisms between different guide rail orientations, enable three-dimensional cab movement, and provide flexible routing options. This multi-functionality allows a single system to handle various travel routes and maintenance access paths, improving versatility without proportionally increasing complexity
2Adaptability or versatility
If two-dimensional guide rail arrangement is used, then the device complexity is low, but the travel route flexibility is restricted
Solution Approach 1:
By incorporating guide rails in three mutually perpendicular directions (vertical, horizontal, and depth directions) and using rotatable rail segments to connect them, the system enables cabs to travel along complex three-dimensional routes. This allows flexible routing between multiple shafts and destinations while maintaining a relatively organized guide rail structure
3Ease of operation
If traditional elevator shafts are used, then the maintenance access is limited, but the space efficiency is reduced
Solution Approach 1:
The three-dimensional guide rail system enables maintenance personnel to access elevator cabs from multiple directions (vertical access from above/below, horizontal access from side shafts, and depth-direction access). This multi-directional access capability improves maintenance ease while the compact 3D routing optimizes the use of installation space compared to traditional linear shaft arrangements
