Elevator Guide Rail Fastening Arrangement with Nest Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening brackets for elevator guide rails are difficult to access and adjust, especially in the vertical direction, making manual alignment time-consuming and automation challenging due to the placement of fastening members behind the vertical branch, which restricts efficient alignment and installation processes.
Innovation Solution
A fastening arrangement with two bracket parts featuring perpendicular openings and a nest mechanism that allows for vertical and horizontal adjustment of the first fastening member, enabling easy access and automation of guide rail alignment through a power transmission system that converts rotational movement into linear vertical movement, facilitating alignment in both horizontal directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the first fastening member is positioned behind the vertical branch of the bracket part, then the fastening arrangement provides structural support for guide rails, but the access to the first fastening member becomes difficult and manual alignment becomes time-consuming
Solution Approach 1:
The patent introduces a second fastening member that operates in a different spatial dimension (horizontal direction) compared to the first fastening member (vertical direction). This allows alignment operations to be performed from the front of the bracket part, improving accessibility without compromising the structural support function of the first fastening member positioned behind the vertical branch.
Solution Approach 2:
The second fastening member acts as an intermediary that enables alignment operations without directly interfering with the first fastening member's structural support role. By providing an alternative access path through the horizontal direction, the second fastening member mediates between the need for structural integrity and the need for operational accessibility.
2Extent of automation
If the fastening arrangement uses traditional bracket parts with fastening members positioned behind the vertical branch, then the guide rails can be attached to the wall structure, but automation of the alignment process becomes challenging
Solution Approach 1:
The fastening arrangement is segmented into two distinct fastening members (first and second) with different functions and access paths. The first fastening member handles vertical attachment behind the bracket, while the second fastening member handles horizontal alignment from the front. This segmentation allows each component to be optimized for its specific function, facilitating automation while maintaining overall structural integrity.
Solution Approach 2:
The bracket part is designed to accommodate multiple fastening members with different orientations and access paths. This multi-functional design allows the same bracket structure to support both the first fastening member for structural attachment and the second fastening member for alignment operations, enabling automation without requiring entirely separate systems.
3Strength
If the first fastening member is accessed from the vertical direction behind the bracket part, then the fastening arrangement maintains structural integrity, but the accessibility from an installation platform deteriorates
Solution Approach 1:
The patent resolves the accessibility conflict by introducing a second fastening member that operates in the horizontal dimension, perpendicular to the first fastening member's vertical dimension. This allows installation personnel to access and operate the second fastening member from the front of the bracket part using the installation platform, while the first fastening member continues to provide structural support from behind the vertical branch.
Solution Approach 2:
The second fastening member serves as an intermediary that provides the necessary alignment function without compromising the structural role of the first fastening member. It mediates between the need for maintaining structural integrity (first fastening member behind the bracket) and the need for easy accessibility (second fastening member accessible from the front).

Function Achieved in This Case
This solution significantly speeds up manual alignment and enables full automation of guide rail alignment, allowing for efficient and precise adjustment of guide rails, improving installation efficiency and accessibility from an installation platform.
Implementation Method 1
the first fastening member and the second fastening member being operatively connected to each other via a power transmission within the nest, whereby rotation of the second fastening member around a longitudinal centre axis of the second fastening member is transferred in the power transmission to a vertical linear movement of the first fastening element generating a pressure joint

AI summary
The arrangement comprises two bracket parts (210, 220). Each bracket part comprises a vertical branch (211, 221) and a horizontal branch (212, 222) attached by two fastening points (P1, P2). Each fastening point comprises a longitudinal opening (O21, O22) in each horizontal branch and a first fastening member (310) passing vertically through the two longitudinal openings into a nest (213) supported on a horizontal branch. A second fastening member (320) extends horizontally into the nest and is operatively connected within the nest to the first fastening member via a power transmission (330). Rotation of the second fastening member generates a pressure joint between the two horizontal branches in the fastening point.
