Elevator Panel Protection Hanger with Snap Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passenger elevators in buildings without freight elevators often suffer damage from moving large items due to the lack of specialized protection for their decorative panels, which are typically made of materials like wood or metal that can be scratched or marred.
Innovation Solution
A system comprising hangers with snap fasteners and protective sheets is used to securely suspend protective pads over the elevator panels, featuring hooks and apertures that allow easy installation and secure attachment, ensuring the pads cover the panels effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If specialized pads are used to protect elevator panels, then the panels are protected from damage, but the system becomes more complex and requires specialized equipment
Solution Approach 1:
The protective system is divided into separate components: hangers that attach to the elevator ceiling and pads that hang down to protect the panels. This segmentation allows the use of simple, universal components rather than complex specialized equipment, while still providing effective protection against panel damage
Solution Approach 2:
The hangers are designed with universal attachment mechanisms that can be used with various pad types and configurations. The snap fastener system provides a standardized interface that works with different pad materials and sizes, reducing the need for specialized equipment while maintaining protection effectiveness
2Object-affected harmful factors
If pads are suspended over elevator panels, then protection is provided, but installation and removal become time-consuming
Solution Approach 1:
The hangers are pre-installed on the elevator ceiling before the pads are needed. This preliminary action allows the pads to be quickly attached and detached as needed, significantly reducing installation time while maintaining continuous protection capability
Solution Approach 2:
The system uses dynamic attachment mechanisms (snap fasteners) that allow rapid connection and disconnection of pads. This dynamic capability enables quick installation and removal without time-consuming fastening operations, while ensuring secure attachment when installed
3Shape
If decorative panels are used in passenger elevators, then aesthetic appearance is improved, but the panels become susceptible to scratches and marks
Solution Approach 1:
Protective pads are positioned in advance over the decorative panels to cushion against potential damage from moving items. This beforehand cushioning allows the use of aesthetically pleasing decorative panels while preventing scratches and marks before they can occur

AI summary
A system for protecting an elevator including a plurality of wall panels. The system includes a first plurality of hangers each having a suspension portion and a hanger portion. A protective sheet having a plurality of holes along an edge thereof is fastened to the suspension portions by a plurality of snap fasteners inserted through both the aperture of a hanger and a hole of the plurality of holes. The hanger portion engages an upper edge portion of a wall panel of the plurality of wall panels. In some uses, the protective sheet is positioned between the suspension portion and the wall panel of the plurality of wall panels. The hanger portion may be embodied as a hook and the snap fasteners may be embodied as plastic rivets.
