Preassembled Elevator Shaft Top Module With Shiftable Guide Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of elevator systems is complex and costly, particularly due to the difficulty in positioning guide rail pieces and drive units within the elevator shaft, which are typically assembled on-site, leading to inefficiencies and safety concerns.
Innovation Solution
A top module for closing off an elevator shaft is designed with guide rail pieces and a drive unit that can assume transport and operating positions, allowing preassembly and transport to the construction site, with the guide rail pieces and drive unit being fixed in transport positions before installation, and then shifted to operating positions post-installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If guide rail pieces and drive units are assembled on-site in the elevator shaft, then installation flexibility is maintained, but installation time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-assembling guide rail pieces and drive units in a transport state at the factory before transporting them to the construction site. This allows extensive preparatory work to be completed off-site, reducing on-site assembly time and complexity while maintaining installation flexibility through the ability to adjust positions after placement.
2Ease of manufacture
If guide rail pieces are fixed in transport position before installation, then preassembly and transport are simplified, but positioning precision must be adjusted after installation
Solution Approach 1:
The patent applies dynamics by designing the bracket system to allow the guide rail piece to transition from a fixed transport position to an adjustable operating position. The bracket includes adjustment mechanisms that enable precise positioning after installation, combining the benefits of easy preassembly with the ability to achieve high positioning precision on-site.
3Adaptability or versatility
If the top module is designed with movable guide rail pieces, then adaptability to different positions is improved, but structural complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the top module into separate functional components: the bracket structure, the guide rail piece, and the drive unit. This segmentation allows each component to be independently designed and adjusted, providing position adaptability without requiring the entire module to be overly complex. The bracket can be adjusted independently to accommodate different guide rail positions.

AI summary
A top module for closing off an elevator shaft of an elevator system has a first top module side wall and a top module ceiling, a first guide rail piece fixed by a bracket on the first top module side wall, and a drive unit connected to the first guide rail piece. The top module can assume an operating state and a transport state. In the operating state, the first guide rail piece and the drive unit assume operating positions, and a car of the elevator system can be moved in the elevator shaft closed off with the top module. In the transport state, the first guide rail piece and the drive unit assume transport positions that deviate from the operating positions.
