Rolling Door Two-Way Operator Logic for Alarm Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling doors with single-direction mechanical controls for alarm situations are insufficient, as they cannot adapt to different types of alarms, such as requiring an open state for evacuation and a closed state for security, and lack effective error detection and notification mechanisms.
Innovation Solution
Implementing a two-way operator logic system with electrical control using a controller, sensors, and a motor to differentiate between alarm types and automatically open or close the door accordingly, with visual and audible error notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single-direction mechanical control is used for alarm situations, then the door can be controlled to move in one default direction, but the system cannot adapt to different alarm types requiring different door states
Solution Approach 1:
The patent replaces the traditional mechanical control system with an electrical control system using a motor and controller. This substitution enables the door to respond differently to various alarm types (evacuation vs. security) through electrical signals rather than mechanical linkages, resolving the contradiction by providing adaptability while maintaining manageable complexity through electronic control logic.
Solution Approach 2:
The control system is made dynamic by implementing two-way operator logic that can selectively command the door to open or close based on the type of alarm detected. The system transitions from a static single-direction control to a dynamic multi-state control system that adapts its response based on real-time alarm conditions.
2Adaptability or versatility
If electrical control with two-way operator logic is implemented, then the door can adapt to different alarm types, but the device complexity increases
Solution Approach 1:
The controller is designed as a universal component that handles multiple alarm types (evacuation alarms, security alarms, sensor errors) through a single device. The two-way operator logic provides multi-functionality by enabling both opening and closing operations from one control system, reducing the need for separate control mechanisms for different scenarios.
Solution Approach 2:
The system implements feedback mechanisms through sensors that detect alarm conditions and door position, and through visual/audible notifications that provide status information. This feedback loop enables the controller to make informed decisions about door operation and to notify users of system state or errors, managing complexity through intelligent control rather than additional hardware.
3Reliability
If mechanical controls are used during power failures, then the door can still be operated manually, but error detection and notification capabilities are lost
Solution Approach 1:
The system provides self-service error detection and notification through visual (LED indicators) and audible (siren) components that automatically detect and communicate system states without requiring external monitoring. During power failures, the system can detect the condition and notify users through remaining functional components, maintaining error detection capability without requiring continuous external intervention.
Solution Approach 2:
The system prepares for potential failures by incorporating redundant notification methods (visual and audible) and manual operation capability. These provisions are built in advance to cushion against the loss of electrical power, ensuring that error detection and basic operation remain possible even when primary electrical systems fail.
4Productivity
If sensor errors are not detected, then the system operates without interruption, but incorrect door operation may occur during alarm situations
Solution Approach 1:
The controller continuously receives feedback from sensors monitoring door position and alarm conditions. This feedback enables real-time detection of sensor errors or abnormal states, allowing the system to identify when sensors are providing incorrect information and prevent incorrect door operation while maintaining continuous monitoring for reliability.
Solution Approach 2:
The system takes preliminary anti-action by detecting sensor errors before they can cause incorrect door operation. The controller monitors sensor signals and can identify erroneous readings, preventing the system from making wrong decisions about door state based on faulty sensor data.

AI summary
In example implementations, a method executed by a processor of a controller of a rolling door system is provided. The method includes receiving an alarm signal, determining a type of alarm associated with the alarm signal, and transmitting a control signal to operate a motor to open or close a rolling door in response to the type of alarm that is determined.
