Emergency Operating Device for Building Element Drive Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic door or window systems often require external service personnel to restore operation after a fault, leading to unsatisfactory situations where security or environmental control is compromised.
Innovation Solution
An emergency operating device is integrated into the system, allowing on-site users to manually activate the drive for opening or closing the component using a user-actuated element, such as a button, following a fault condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system enters a safe state after a fault to prevent dangerous situations, then safety is improved, but the component cannot be moved and external service personnel are required, worsening ease of operation and loss of time
Solution Approach 1:
The patent enables users to perform emergency operations themselves without requiring external service personnel. The emergency operating device allows on-site personnel to manually activate the drive and move the component even when the control device is in a fault state, making the system self-service capable for emergency situations.
Solution Approach 2:
The patent separates the emergency operating device from the normal control device. The emergency operating device is a distinct component with its own actuating element that can independently activate the drive, separate from the control device's normal operation modes. This segmentation allows emergency functionality to operate independently when the control device fails.
2Reliability
If the system enters a safe state after a fault, then safety is improved, but productivity decreases due to component immobility and waiting for service personnel
Solution Approach 1:
Users can independently restore component mobility through the emergency operating device without waiting for service personnel, maintaining productivity during fault conditions. The system enables self-restoration of functionality while preserving safety through the fault state monitoring.
Solution Approach 2:
The emergency operating device is prepared in advance and can be immediately activated when needed. The drive mechanism and emergency actuating elements are pre-configured to enable immediate emergency operation without requiring additional setup or waiting for external assistance.
3Reliability
If the drive has a self-locking gear to prevent manual movement, then reliability is improved by preventing unauthorized operation, but ease of operation worsens when manual intervention is needed
Solution Approach 1:
The emergency operating device acts as an intermediary between the user and the self-locking drive mechanism. It provides a controlled interface that can temporarily override the self-locking function during emergency operations, then restore the locking state afterward, mediating between security requirements and emergency intervention needs.
Solution Approach 2:
Users can independently operate the emergency device to move the component despite the self-locking gear, enabling self-service emergency operations without requiring mechanical forcing or damage to the drive mechanism.

AI summary
The invention relates to a device for opening and/or closing a building element, in particular a door or window, which has at least one movable component, in particular a hinged, pivoting or tilting sash or a door leaf, comprising a drive for the movable component, a safety device comprising at least one sensor for monitoring a danger point in the area of the building element during an opening and/or closing movement of the component effected by means of the drive, and a control device configured to open and/or close the building element by means of the drive, in particular automatically, in normal operation, and in the event of a malfunction, in particular a dangerous situation detected by means of the sensor or a fault, to stop or reverse the current opening and/or closing movement of the component and/or to establish a safe state.in which movement of the component by means of the drive is prevented, wherein an emergency operating device is provided for emergency operation, which includes at least one actuating element to be actuated by a user and is designed to cause the drive to effect an opening or closing movement of the component when the actuating element is actuated.
