Side-Mount Elevator Hanger Assembly for Easier Wall Panel Renovation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator ceiling panels are often damaged during renovations due to their rigid connection to the car walls, and there is a need for a mounting system that allows for easier access and replacement of wall panels without removing the ceiling panels, while also reducing wear and damage to the car walls.
Innovation Solution
A side mount hanger system that includes upper and lower walls with horizontal and vertical mounting channels, allowing for sliding fasteners and lateral clearance, enabling the ceiling panel to be mounted to the elevator car wall without damaging the wall panels and allowing for easier installation and replacement of wall panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ceiling panels are rigidly connected to car walls, then structural stability is improved, but ease of repair deteriorates (ceiling panels cannot be accessed during renovations)
Solution Approach 1:
The mounting system is divided into separate components: a hanger assembly with mounting channels and fasteners, and the ceiling panel itself. This segmentation allows the ceiling panel to be detached from the car wall by removing the fasteners from the mounting channels, enabling wall panel renovations without removing ceiling panels while maintaining structural stability when assembled.
Solution Approach 2:
The mounting system transitions from a rigid permanent connection to a dynamic removable connection. The fasteners can be inserted into and removed from the mounting channels, allowing the ceiling panel to be easily installed and removed. This dynamic connection enables renovations while maintaining structural integrity during normal operation.
2Stability of the object's composition
If ceiling panels are rigidly connected to car walls, then structural stability is improved, but loss of time increases (renovation requires removing ceiling panels)
Solution Approach 1:
By segmenting the mounting system into a hanger assembly with mounting channels and detachable fasteners, the ceiling panel can be quickly removed and reinstalled during renovations without requiring removal of wall panels or complex disassembly procedures, significantly reducing renovation time while maintaining structural stability.
Solution Approach 2:
The fasteners can be easily removed from the mounting channels during renovations and then reinstalled afterward. This allows rapid disassembly and reassembly of the ceiling panel mounting system during renovation activities, minimizing downtime and loss of time while preserving structural integrity.
3Device complexity
If ceiling panels are mounted directly to car walls, then device complexity is reduced, but object-generated harmful factors increase (wear and damage to car walls)
Solution Approach 1:
The hanger assembly with mounting channels serves as an intermediary component between the ceiling panel and the car wall. This intermediary distributes the mounting forces across a larger area and provides a cushioning interface that reduces direct contact stress and friction on the car wall surface, thereby reducing wear and damage while adding only moderate complexity to the mounting system.
4Manufacturing precision
If ceiling panels are mounted with precise alignment, then manufacturing precision is improved, but ease of operation deteriorates (difficult to align during installation)
Solution Approach 1:
The mounting channels are designed with specific geometric parameters including length, width, and orientation that accommodate a range of alignment tolerances. The channels can receive fasteners at various positions along their length, allowing installers to adjust the mounting position and achieve proper alignment without requiring extremely precise initial positioning, thereby easing the installation operation while maintaining sufficient alignment precision.

AI summary
Embodiments of an elevator mounting assembly are provided. The elevator mounting assembly includes an elevator wall panel that is coupled to an elevator car wall by a hanger, specifically a side mount hanger. The hanger includes a lower wall that is spaced laterally apart from the elevator wall panel. At least a portion of the lower wall is in lateral alignment with the elevator wall panel. An intermediate wall extends from the lower wall in a direction toward the elevator car wall. Further, an upper wall extends from the intermediate wall, such that the upper wall is positioned nearer than the lower wall to the elevator car wall. The upper wall is coupled to the elevator car wall at a location above the elevator wall panel. Additionally, an elevator ceiling panel is coupled to the lower wall. In specific embodiments, the upper wall includes a plurality of wall mounting channels.
