Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator construction methods require significant on-site assembly, leading to inefficiencies, delays, and complications in logistics and accuracy of component placement.
Innovation Solution
A method involving the fabrication of elevator modules at a location apart from the destination, with modules being positioned horizontally for efficient installation work, and then transported and stacked vertically for assembly, utilizing beam frames with tubular metal beams for rigidity and ease of alignment using laser devices for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If elevator components are installed one by one at the construction site, then the elevator can be assembled in place, but the construction process consumes more time and complicates logistics
Solution Approach 1:
The elevator is divided into modular components (car, counterweight, guide rails, machinery room) that are manufactured separately and then assembled on-site. This segmentation allows parallel manufacturing of components while maintaining ease of on-site assembly through standardized interfaces.
Solution Approach 2:
Elevator components are pre-assembled into complete modules at the factory before transportation to the construction site. The modules are pre-configured with all necessary sub-components and connections, eliminating the need for time-consuming on-site assembly of individual parts.
2Manufacturing precision
If components are positioned and adjusted at the construction site, then accurate placement can be achieved, but this causes delays in subsequent construction steps
Solution Approach 1:
All positioning and alignment adjustments are performed at the factory during module assembly, ensuring high precision through controlled manufacturing environments. The modules arrive at the construction site ready-for-installation with pre-adjusted components, eliminating time-consuming on-site adjustments.
Solution Approach 2:
Traditional mechanical adjustment methods on-site are replaced with precision manufacturing and standardized mounting interfaces. Laser alignment tools and pre-drilled connection points ensure accurate positioning without requiring time-consuming manual adjustments at the construction site.
3Productivity
If modular elevator solutions are used with prefabricated modules, then assembly speed is improved, but fabrication efficiency and accuracy of module production need enhancement
Solution Approach 1:
The elevator system is segmented into standardized modules (car module, counterweight module, guide rail module, machinery module) that can be independently manufactured and assembled. This standardization enables parallel fabrication processes and improves overall production efficiency while maintaining fast on-site assembly.
Solution Approach 2:
The module design incorporates universal interfaces and standardized connection points that can accommodate different elevator configurations. This universality allows the same fabrication processes to produce multiple module types, improving manufacturing efficiency through process reuse while maintaining assembly speed.

AI summary
A method for constructing an elevator into a destination location from a plurality of prefabricated elevator modules includes fabricating a plurality of elevator modules, in particular at a location apart from said destination location. The fabricating includes providing one or more module frames having a longitudinal axis; positioning one or more of the module frames in horizontally oriented position, wherein in the horizontally oriented position the longitudinal axis is horizontal; and while the one or more module frames are in the horizontal position, performing installation work on said one or more module frames. The method includes arranging the modules into the destination location on top of each other such that said modules are in a vertically oriented position.
