Floor-Mounted Elevator Guide Rail Bracket for Shaft Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems face challenges in efficiently utilizing the available space within the elevator shaft due to the installation of guide rails, which are typically fixed using brackets that occupy a significant portion of the usable cross-sectional area, thereby reducing the effective space for the elevator car's movement.
Innovation Solution
An elevator system with an installation bracket that is designed to be fixed to the horizontal floor surface, allowing the crossmember to be positioned entirely within the floor landing, with side members extending into the shaft space, ensuring a stable and space-efficient connection of guide rails to the door-side shaft wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the installation bracket is designed with crossmember and legs extending into the elevator shaft, then the guide rails can be securely fastened to the shaft wall, but the usable shaft space is reduced
Solution Approach 1:
The installation bracket is repositioned from extending into the shaft space to being mounted on the floor landing. The crossmember is arranged substantially entirely within the floor landing, utilizing the horizontal dimension of the floor rather than occupying vertical shaft space. This dimensional shift resolves the contradiction by providing secure mounting without reducing usable shaft volume.
Solution Approach 2:
The crossmember is extracted from the shaft space and relocated to the floor landing. By separating the mounting function (performed by the crossmember on the floor) from the guidance function (performed by the side members in the shaft), the design eliminates the occupation of shaft space by the main body of the bracket while maintaining connection stability.
2Ease of operation
If the crossmember is positioned within the floor landing, then the installer safety is improved and shaft space is optimized, but the mounting complexity increases
Solution Approach 1:
The floor landing serves multiple functions: it provides a safe working surface for installers, acts as the mounting foundation for the crossmember, and optimizes shaft space utilization. By making the floor landing a multi-functional element, the design achieves safety and space optimization without proportionally increasing mounting complexity.
Solution Approach 2:
The installation bracket is segmented into distinct functional parts: the crossmember for floor mounting and the side members for guide rail attachment. This segmentation allows each part to be optimized independently - the crossmember for safe floor-level installation and the side members for precise shaft-space positioning - thereby managing overall complexity through modular design.

AI summary
A mounting bracket for mounting to a hoistway door opening of an elevator system includes a transverse support extending in a first direction and two lateral supports connected to and extending away from the transverse support. The transverse support has a floor fixing portion adapted to be fixed to a horizontal surface of the floor landing at the door opening. Each of the lateral supports has a rail fastening portion that extends parallel to the first direction and includes at least one mounting opening for fastening a guide rail for guiding an elevator car.
