Automatic Door Operator Manual Movement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic door operators in public areas face challenges in providing a clean and aesthetically appealing installation while allowing user interaction, as they often require visible components and separate controls, which can be costly and prone to wear and tear, and lack efficient methods for human intervention.
Innovation Solution
An automatic door operator system that detects intentional manual movements of the door leaf and uses them as commands to control functions, such as opening, closing, or initiating fire alarms, through a configured controller and linkage mechanism, allowing for user interaction without external buttons or actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate buttons, actuators, and wiring are used for user interaction, then user control capability is improved, but installation cleanliness and aesthetic appeal deteriorate
Solution Approach 1:
The patent extracts the external control components (buttons, actuators) and replaces them with direct door leaf interaction. The door leaf itself becomes the control interface through detection of manual movements, eliminating the need for separate external control devices while maintaining user control capability.
Solution Approach 2:
The patent introduces the controller as an intermediary that detects manual movements of the door leaf and translates them into control commands. This mediator enables communication between the user's physical interaction with the door and the automatic door operator's control system without requiring external buttons or actuators.
2Ease of operation
If separate buttons and actuators are installed, then user interaction is enabled, but cost and wear and tear increase
Solution Approach 1:
The patent removes external buttons and actuators from the system, eliminating components that are exposed to wear and tear. The door leaf, which is already part of the system and subject to regular use, becomes the control interface, thereby eliminating additional wear-prone components.
Solution Approach 2:
The door leaf serves dual purposes: it is both the operational element that moves to open/close the door and the control interface for user interaction. This self-service approach eliminates the need for separate control components that would otherwise be subject to wear and tear.
3Device complexity
If the door operator is completely automatic, then installation simplicity is improved, but user control flexibility deteriorates
Solution Approach 1:
The patent introduces dynamic control capabilities to the automatic door operator by enabling detection of manual door leaf movements. The system can adapt its behavior based on detected user actions, such as aborting hold-open periods or initiating fire alarms, thereby providing control flexibility while maintaining installation simplicity.
Solution Approach 2:
The controller detects manual movements of the door leaf and uses this feedback to determine appropriate control functions to execute. This feedback mechanism enables the automatic system to respond to user intentions, providing control flexibility without requiring separate control devices.

AI summary
An automatic door operator (30) for a swing door assembly (10) having a door leaf (14) rotationally supported by a door frame (12) is disclosed. The automatic door operator has a motor (34) for causing opening of the door leaf (14) with respect to the door frame (12), and a controller (31) being configured for performing different functions (60) of the automatic door operator. The controller (31) is configured to detect (42) a movement of the door leaf (14), not caused by the motor (34), identify (44) a predefined movement matching the detected movement, determine (46), among the different functions, a function (61-A, 61-B) being associated with the predefined movement, and perform (48) the determined function.
