Elevator Door Glass Fixing Apparatus with Elastic Rear Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing ornamental glass sheets on elevator doors require disassembly of the entire door for replacement, leading to high maintenance time and cost, as well as safety risks.
Innovation Solution
A fixing apparatus comprising an elastic rear sheet and a fixing means with screws, bolts, and covers along the edges of the glass sheet, allowing for external attachment and detachment without disassembling the door, featuring supports, props, and cross-supports for enhanced stability and aesthetic integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the glass sheet is firmly fixed by L-shaped supports and U-shaped couplers to the elevator door, then the glass sheet is securely attached, but the entire door must be disassembled for replacement, increasing maintenance time and cost
Solution Approach 1:
The fixing apparatus is divided into separate modular components: U-shaped couplers for top and bottom edges, L-shaped supports for side edges, and an elastic rear sheet. These segmented components can be independently installed and removed, allowing the glass sheet to be replaced without disassembling the entire door structure.
Solution Approach 2:
The elastic rear sheet is pre-installed on the elevator door before the glass sheet is attached. This preliminary action creates a ready-made mounting surface that simplifies subsequent glass sheet installation and removal, eliminating the need for complex door disassembly during maintenance.
2Strength
If the glass sheet is firmly fixed by L-shaped supports and U-shaped couplers to the elevator door, then the glass sheet is securely attached, but many safety accidents may occur while replacing the glass sheet
Solution Approach 1:
By segmenting the fixing system into removable components (U-shaped couplers, L-shaped supports) rather than a fixed door structure, the invention enables safe external replacement operations without requiring workers to disassemble the entire door, thereby reducing safety risks.
Solution Approach 2:
The elastic rear sheet acts as an intermediary between the glass sheet and the elevator door structure. It provides a flexible mounting surface that absorbs stress and allows for easier, safer removal and replacement of the glass sheet without direct manipulation of the rigid door structure.
3Shape
If the glass sheet is attached in advance to an elevator door before the elevator is installed in a building, then the aesthetic quality is improved, but replacement requires disassembly of the entire door
Solution Approach 1:
The fixing apparatus uses segmented components (U-shaped couplers, L-shaped supports) that can be independently installed and removed. This segmentation maintains the aesthetic appearance when installed but enables easy replacement by removing only the fixing components rather than disassembling the entire door.
Solution Approach 2:
The elastic rear sheet provides dynamic flexibility to the fixing system. While maintaining firm attachment for aesthetic purposes during normal operation, it allows for easy detachment and reattachment during replacement, transforming the system from static to dynamically adaptable.
