Automatic Door Drive Mode Switching via Manual Movement Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic door drives require cumbersome manual switching between operating modes, especially when the mode switch is difficult to access, limiting user convenience.
Innovation Solution
An automatic door drive system with a position transmitter and evaluation and control unit that automatically switches between modes based on manual movement detection, allowing the door to remain open permanently when manually pushed further, and re-closing after a predetermined hold-open or safety period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door drive requires manual switching between operating modes, then the operating modes can be changed, but the user convenience deteriorates when the mode switch is difficult to access
Solution Approach 1:
The door drive system automatically detects manual door movement and self-switches from automatic mode to permanently open mode without requiring user interaction with the program switch. The control unit monitors position sensor signals and autonomously changes operating modes based on detected movement patterns, making the system serve itself rather than requiring manual mode switching
Solution Approach 2:
The system uses position sensor feedback to detect when the door is manually moved beyond the open position. This feedback mechanism allows the control unit to recognize user intent and automatically adjust the operating mode accordingly, eliminating the need for separate mode switching operations
2Duration of action of moving object
If the door automatically closes after a preset hold-open period, then the door can be temporarily held open, but the door cannot remain permanently open without mode switching
Solution Approach 1:
The system dynamically transitions from a time-based automatic closing mode to a position-based permanently open mode based on real-time detection of manual door movement. This dynamic adaptation allows the door to remain open indefinitely when needed, while still maintaining automatic closing functionality when no manual extension is detected
3Adaptability or versatility
If the door can be manually moved further beyond the open position, then the user can indicate permanent open intent, but the system must reliably detect this movement to switch modes
Solution Approach 1:
The system replaces mechanical movement detection with electronic position sensor monitoring. The sensor provides precise electronic signals about door position, allowing the control unit to accurately detect when the door has been manually moved beyond the normal open position and automatically switch modes based on this precise measurement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple and rapid mode switching, ensuring the door remains open when manually held and closes safely when not in use, enhancing user convenience and preventing unintentional openness.

AI summary
The invention relates to an automatic door drive (1) with a drive unit (20) and an evaluation and control unit (10), which automatically opens and closes a door leaf (3) by means of the drive unit (20), wherein the evaluation and control unit (10) automatically closes the door leaf (3) again in a first operating mode (BA) after a predetermined holding time and moves it from the open position to the closed position, and wherein the evaluation and control unit (10) permanently holds the door leaf (3) in the open position in a second operating mode (BD), as well as an operating method for such an automatic door drive (1).According to the invention, the drive unit (20) has a position sensor (22) whose output signals are evaluated by the evaluation and control unit (10) to determine a current position of the door leaf (3), wherein the evaluation and control unit (10) activates the second operating mode (BD) when the evaluation and control unit (10) detects in the open position that the door leaf (3) is being moved manually further in the opening direction.
