Side-Mount Elevator Hanger for Ceiling-Safe Wall Panel Access
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 easy access and replacement of wall panels without removing the ceiling panels, while also reducing installation precision and wear on the car walls.
Innovation Solution
A side mount hanger system that includes upper, lower, and intermediate walls with mounting channels, allowing for sliding fasteners and lateral clearance, enabling the ceiling panel to be mounted to the elevator car wall with reduced risk of damage and facilitating 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 securely mounted during normal operation while enabling easy removal and replacement during renovations by simply detaching the fasteners.
Solution Approach 2:
The mounting system transitions from a static rigid connection to a dynamic adjustable connection. The mounting channels allow the fasteners to be positioned at different locations, and the entire assembly can be easily disassembled and reassembled, providing flexibility for maintenance and renovations while maintaining stability during operation.
2Manufacturing precision
If ceiling panels are rigidly connected to car walls, then manufacturing precision is improved, but ease of operation deteriorates (difficult to access wall panels)
Solution Approach 1:
By separating the mounting function (hanger assembly) from the ceiling panel, the system allows wall panels to be accessed and replaced independently. The mounting channels and fasteners provide precise positioning capabilities while enabling easy operation during renovations.
Solution Approach 2:
The hanger assembly acts as an intermediary between the ceiling panel and the car wall. This intermediate structure provides the mounting function while creating accessible space between the ceiling panel and the wall, allowing workers to access and replace wall panels without removing ceiling panels.
3Reliability
If ceiling panels are rigidly connected to car walls, then reliability is improved, but object-affected harmful factors worsen (damage to ceiling panels during renovations)
Solution Approach 1:
The mounting function is extracted from the ceiling panel itself and placed in a separate hanger assembly. This allows the ceiling panel to be removed from the renovation process entirely, as wall panels can be accessed and replaced by working through the mounting channels without touching the ceiling panels, eliminating the risk of damage.
Solution Approach 2:
The mounting system is designed in advance to accommodate renovation activities. The mounting channels and removable fasteners are built into the system before renovations occur, providing a pre-planned solution that protects ceiling panels from damage during future wall panel replacements.
4Strength
If ceiling panels are rigidly connected to car walls, then strength is improved, but device complexity worsens (complex mounting system required)
Solution Approach 1:
The hanger assembly serves multiple functions: it provides structural support for the ceiling panel, enables easy removal and replacement, allows access to wall panels, and maintains precise positioning. This multi-functionality reduces the need for multiple separate components, simplifying the overall system while maintaining strength.

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.
