Adjustable Elevator Installation Platform for Variable Shaft Dimensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator installation platforms are not adaptable to different shaft dimensions, leading to inefficiencies and safety concerns during construction, as they are typically designed for specific horizontal dimensions and must be dismantled after use, limiting their reusability and increasing the risk of accidents.
Innovation Solution
An adjustable installation platform with adjustable width and depth, allowing it to fit various shaft dimensions, enabling reuse and minimizing safety risks by allowing manual or automatic operation with industrial robots, and facilitating early assembly and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the installation platform is designed for specific horizontal dimensions, then it can be used in a particular shaft, but it cannot be reused in shafts with different dimensions and must be dismantled after use
Solution Approach 1:
The installation platform employs adjustable support legs with telescopic sections that can be extended or retracted to accommodate different shaft dimensions. The support legs include locking mechanisms that allow the platform to be dynamically adjusted to fit various horizontal distances between guide rails and back walls, enabling reuse across multiple shaft configurations without dismantling the entire platform structure.
Solution Approach 2:
The platform's horizontal dimensions are made variable through adjustable support legs that can change their length. By modifying the length parameter of the support legs, the platform adapts to different shaft sizes. This parameter adjustment capability allows the same platform to be used in shafts with varying distances between guide rails and back walls, eliminating the need for custom-built platforms for each shaft.
2Reliability
If the installation platform is fixed in size, then it is simpler to manufacture, but it creates safety risks when entering and leaving through landings and increases the risk of objects falling
Solution Approach 1:
The adjustable support legs allow the platform to be precisely sized to match each shaft's dimensions, minimizing gaps between the platform edge and the landing. This dynamic adjustment capability ensures that the platform can be optimally positioned for safe entry and exit while preventing objects from falling, without requiring overly complex fixed safety structures.
Solution Approach 2:
The same adjustable platform structure serves multiple functions: it provides a safe working surface, enables secure entry and exit through optimized positioning, and prevents object falling through proper gap control. The adjustability mechanism itself becomes a universal feature that addresses multiple safety concerns simultaneously, rather than requiring separate safety devices for each issue.
3Productivity
If the installation platform is dismantled after use in one shaft, then it can be stored, but construction time is lost and reusability is limited
Solution Approach 1:
The adjustable support legs can be quickly reconfigured from one shaft dimension to another without complete dismantling. The telescopic sections with locking mechanisms allow rapid adjustment of the platform's horizontal dimensions, enabling the platform to be moved between different shafts with minimal setup time, thereby improving productivity and reducing the loss of construction time.
Solution Approach 2:
The platform is designed as a universal installation platform that can serve multiple shafts with different dimensions. The adjustable support legs enable the same platform structure to be adapted to various shaft configurations, eliminating the need to build and dismantle separate platforms for each shaft. This multi-functionality significantly reduces the time lost to dismantling and reassembly operations.

AI summary
The installation platform comprises two decks and a support frame comprising horizontal support beams supporting a respective deck and vertical support beams. The installation platform has a width in a first horizontal direction between the guide rails, a depth in a second horizontal direction perpendicular to the first horizontal direction. The installation platform is guided movably via guide means on the guide rails. At least one of the width and the depth of the installation is adjustable in order to adjust the horizontal dimensions of the installation platform according to the horizontal dimensions of the shaft.
