Ropeless Elevator Cabin Support via Wall-Mounted Sledge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems in horizontal shafts face space constraints and safety challenges due to traditional support structures, limiting the size of elevator cars and passenger capacity, and are not adaptable to environmental changes.
Innovation Solution
A ropeless elevator system with a sledge mechanism and rucksack suspension system that supports the elevator cabin, allowing it to switch between vertical and horizontal shafts, incorporating auxiliary mechanisms like levelling, damping, and locking systems for improved safety and space efficiency, and using lightweight composite materials for weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional car support with horizontal and vertical legs is used, then the elevator car is supported structurally, but the space requirement about the exterior of the elevator car increases substantially
Solution Approach 1:
The patent extracts the support function from the traditional car support structure and relocates it to the shaft wall. The car support no longer needs horizontal and vertical legs extending outward, but instead connects directly to the shaft wall, eliminating the substantial space requirement about the exterior of the elevator car while maintaining structural support.
Solution Approach 2:
The support structure transitions from a three-dimensional outward-extending configuration (horizontal and vertical legs) to a two-dimensional planar configuration against the shaft wall. This dimensional change allows the support structure to be integrated into the shaft wall surface, reducing the spatial footprint.
2Strength
If a forklift-like car support structure is used, then the elevator car is supported, but the amount of space required below the elevator cabin floor increases
Solution Approach 1:
The support function is extracted from the forklift-like structure that extends below the cabin floor and relocated to the shaft wall. The car support connects to the shaft wall at a point above the cabin floor level, eliminating the need for substantial space below the cabin floor while maintaining the support capability.
3Force
If the elevator car is supported by a carrier, then the weight is passed through the car floor, but the space requirement about the exterior of the elevator car increases
Solution Approach 1:
The weight transmission function is extracted from the car floor and relocated to the shaft wall. The car support connects the cabin to the shaft wall, allowing the weight to be transmitted through the support structure to the shaft wall foundation, eliminating the need for substantial exterior space about the elevator car.
