Modular Elevator Shaft Layout With Speed-Based Headroom Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The creation of elevator shafts is complex and costly, requiring non-standardized top modules due to varying free space requirements based on nominal speed and safety standards, which complicates production and increases costs.
Innovation Solution
A method involving a standardized top module and an intermediate element with adjustable height, determined by nominal speed and safety considerations, to ensure consistent free space, allowing for the use of identical components across different elevator systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different top modules are used for different nominal speeds and safety standards, then the free space requirements are met, but the production complexity and costs increase
Solution Approach 1:
The elevator shaft is divided into modular sections (base modules, intermediate elements, top module) that can be independently manufactured and assembled. The intermediate element serves as a standardized segment that adapts to different speed requirements without changing the top module design.
Solution Approach 2:
A universal top module design is created that can be used across different elevator systems regardless of nominal speed. The intermediate element acts as an adaptable component that adjusts the overall configuration to meet different free space requirements while maintaining compatibility with the standardized top module.
2Reliability
If non-standardized top modules are manufactured for each elevator system, then specific safety requirements are met, but production costs and time increase
Solution Approach 1:
Instead of changing the top module design for different parameters, the intermediate element's dimensions are adjusted to accommodate different nominal speeds and safety standards. This allows the top module to remain standardized while adapting to various operational requirements through parameter modification of the intermediate component.
Solution Approach 2:
The intermediate element is pre-configured with specific dimensions based on anticipated free space requirements. This preliminary determination of the intermediate element's height allows for standardized top module production while still meeting specific safety and operational requirements for each elevator system.
3Reliability
If the top module height is increased to provide sufficient free space, then safety requirements are met, but the standardization benefit is reduced
Solution Approach 1:
The vertical space requirement is segmented between the intermediate element and the top module. The intermediate element provides the necessary height adjustment for safety space requirements, while the top module maintains a standardized design that can be universally applied across different elevator systems.
Solution Approach 2:
The intermediate element acts as an intermediary component between the base modules and the top module. It mediates the conflict between safety space requirements and standardization by providing the necessary vertical dimension without requiring customization of the top module itself.

AI summary
A method for creating an elevator shaft for an elevator system, wherein the elevator shaft is oriented mainly vertically, uses a plurality of base modules placed on one another. The shaft is upwardly closed off by a top module and forms a travelway for a car of the elevator system. In a normal operation of the elevator system, the car is moved at a nominal speed within the travelway. According to the method, an intermediate element having an intermediate element height is arranged between an uppermost one of the base modules and the top module, wherein the intermediate element height is dependent on the nominal speed of the car.
