Solution Overview
Problem
The installation and manufacturing of conventional elevator guide rail brackets are time-consuming and costly due to the need for manual installation and complex structures, and they do not effectively accommodate longitudinal movement caused by building settling.
Innovation Solution
A guide rail bracket with a simple structure featuring fixed claws and fastening elements that form a claw coupling with the guide rail section, allowing for easy attachment and longitudinal movement without separate correcting structures, enabling automated installation and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional guide rail brackets with separate connecting elements and nut-and-bolt fixing are used, then the guide rail can be securely attached to the base, but the installation process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent combines the connecting element and the fastening elements into an integrated guide rail bracket structure. The U-shaped connecting element forms a receiving space that directly receives the guide rail section, while fastening elements are arranged within this receiving space to secure the guide rail section in place. This merging eliminates the need for separate installation steps and reduces the number of components, thereby reducing installation time while maintaining secure attachment.
Solution Approach 2:
The guide rail bracket is pre-assembled with the connecting element and fastening elements in their correct positions before installation. The receiving space is pre-formed to match the guide rail section geometry, and fastening elements are pre-positioned within this space. This preliminary preparation allows for faster on-site installation as the bracket is ready-to-use and requires minimal assembly during the installation process.
2Reliability
If conventional guide rail brackets with complicated structures are used, then the guide rail can be securely attached, but the manufacturing cost increases
Solution Approach 1:
The guide rail bracket is divided into distinct functional segments: the U-shaped connecting element that forms the receiving space, and the fastening elements that secure the guide rail section. This segmentation allows each component to be manufactured independently using standard fabrication processes, simplifying manufacturing and reducing costs compared to complex monolithic structures.
Solution Approach 2:
The connecting element serves multiple functions: it provides the structural framework of the bracket, forms the receiving space for the guide rail section, and positions the fastening elements. This multi-functionality reduces the number of separate components needed, simplifying the overall structure and reducing manufacturing complexity and cost.
3Stability of the object's composition
If additional correcting structures are added to counteract longitudinal movement, then the guide rail stability improves, but the device complexity increases
Solution Approach 1:
The patent incorporates longitudinal movement capability into the bracket design, allowing the guide rail section to move along the longitudinal axis within the receiving space of the connecting element. This dynamic feature enables the system to accommodate building settling and thermal expansion without requiring additional correcting structures, maintaining stability while avoiding increased complexity.
Solution Approach 2:
The bracket design allows for parameter changes in the longitudinal direction through the movement capability. The receiving space is designed with sufficient clearance and the fastening elements are positioned to allow longitudinal adjustment, enabling the system to adapt to dimensional changes in the elevator shaft and building structures during settling without requiring complex correcting mechanisms.

AI summary
The invention concerns an elevator guide rail bracket for securing a guide rail section to a base via a counterpart, the guide rail bracket comprising a face, a pair of fixed claws arranged into the face, and a fastening part with fastening elements. The claws form a claw coupling with the guide rail section. The claw coupling has a fitting position and a retaining position. The guide rail bracket is attached to the guide rail section by fitting the guide rail section between the claws and turning the guide rail bracket from the fitting position to the retaining position.
