Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator frames with large vertical connection members face issues such as offset, distortion, or mismatch during assembly, which complicates the fixing process and can lead to inaccuracies and potential stress.
Innovation Solution
A position adjusting device for elevator frames, comprising a connection portion attachable to the side surface of vertical connection members, a matching portion with threaded holes, and an adjusting mechanism with a threaded rod, allowing for flexible adjustment of the relative position between vertical and horizontal connection members, which can be fixed using bolts or welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If vertical connection members with large vertical dimension (5-6 meters) are used in elevator frame, then the elevator can accommodate double-deck or double-car configurations, but the distal ends of vertical connection members are prone to offset, distortion or mismatch during assembly
Solution Approach 1:
The position adjusting device segments the connection between vertical and horizontal members by introducing adjustable connecting pieces with multiple mounting holes. This allows the connection to be made in discrete, adjustable increments rather than as a single fixed connection, enabling precise positioning of the distal ends even for 5-6 meter vertical members.
Solution Approach 2:
The connecting piece is designed to be adjustable rather than fixed, with multiple mounting holes that allow repositioning during assembly. This dynamic adjustment capability enables the distal ends of long vertical connection members to be precisely aligned and positioned, resolving the offset and distortion issues that would occur with rigid fixed connections.
2Stability of the object's composition
If vertical connection members are required to be relatively fixed with horizontal connection members, then structural stability is improved, but adjustment of relative position becomes difficult and complex
Solution Approach 1:
The connecting piece transitions from a static fixed connection to a dynamic adjustable connection. The multiple mounting holes allow the connection to be adjusted during assembly to achieve precise positioning, while once positioned, the connection can be securely fixed (by welding or bolting) to maintain stability. This resolves the contradiction between fixity and adjustability.
Solution Approach 2:
The position of the connecting piece can be changed by selecting different mounting holes, allowing adjustment of the relative position between vertical and horizontal members. After adjustment, the connection parameters are locked in place through welding or bolting, achieving both adjustability during assembly and stability in the final structure.
3Ease of manufacture
If traditional fixed assembly methods are used for elevator frame, then assembly process is simple, but accuracy of component alignment deteriorates due to offset and distortion of long vertical members
Solution Approach 1:
The assembly process is segmented into positioning and fixing stages. The adjustable connecting piece allows for easy positioning by selecting appropriate mounting holes, and then the connection is fixed through welding or bolting. This segmentation maintains simplicity while improving precision, as the adjustment capability is built into the connecting piece rather than requiring complex external adjustment mechanisms.
Solution Approach 2:
The adjustable connecting piece serves as an intermediary between the vertical and horizontal members. It absorbs the complexity of adjustment within itself, providing a simple interface for assembly while enabling precise alignment. The connecting piece mediates between the need for simplicity and the need for precision by incorporating the adjustment mechanism directly into the connection element.
