Elevator Door Frame Emergency Evacuation Control Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems face challenges in emergency evacuation solutions that require significant space, complex manufacturing, and unsightly installations, often compromising aesthetics and increasing construction and assembly efforts.
Innovation Solution
A standard control panel is integrated into a door frame with a hidden emergency evacuation device accessible only to specially instructed personnel, allowing for emergency operations without visible disruptive elements, using a compact design that maintains door frame stability and simplifies manufacturing and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control cabinet is placed near the elevator access door, then the controls are accessible from the public area, but space is allocated and a visible control cabinet door appears next to the access door
Solution Approach 1:
The control cabinet is extracted from the door frame structure and relocated to the elevator shaft, eliminating the need for space next to the access door while maintaining control functionality through remote access or intercom systems
2Ease of operation
If the control unit is located in a door jamb with movable sections, then access to the control unit is allowed, but the manufacture and installation become complex and the movable surface creates an undesirable appearance
Solution Approach 1:
The control unit is extracted from the door jamb and relocated to the elevator shaft, eliminating the need for complex movable door jamb sections while maintaining accessibility through alternative means such as removable panels or remote access interfaces
Solution Approach 2:
The door frame is segmented to include a specific opening for the control panel that simplifies the overall structure, avoiding the need for complex movable sections while still allowing access to control elements
3Reliability
If the emergency evacuation control system is located near the elevator access door, then emergency evacuation can be performed, but the system is highly visible and can lead to misuse
Solution Approach 1:
The emergency evacuation control system is extracted from the visible door area and relocated to the elevator shaft, maintaining emergency functionality while reducing visibility and potential for misuse by ordinary users
Solution Approach 2:
Different control systems are positioned at different locations with different accessibility characteristics - the standard control panel remains accessible near the door for normal operation, while the emergency control system is positioned in the shaft with restricted access for authorized personnel only

AI summary
An elevator comprises an elevator shaft (1), a cabin moved therein by a drive on a rope, at least one brake for braking and holding the rope, and at least two stations on the elevator shaft with access doors (2), each equipped with a control panel (3) and an external push button for ordering the cabin at an opening (10) in a door frame (6). A control unit (4) ensures regular elevator operation, and another control unit enables emergency evacuation. A device for carrying out an emergency evacuation is located on the inside of the door frame (6) facing away from the operating side of the control panel (3) and is operated from the outside of the door frame (6) through the opening (10) after the control panel (3) has been at least partially moved away from the corresponding opening (10).
