Roller Door Control Device with Visual Attitude Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vertically sliding roller doors with high extension in height pose challenges for users at ground level to monitor the position of the roller shutter, risking collisions during movement, especially when the shutter is about to descend.
Innovation Solution
A device with operating members that emit signals indicative of the roller shutter's attitude, connected to an electronic control unit and motorized means, using light-emitting elements to visually inform users of the shutter's movement or stationary state, preventing unsafe crossings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the roller shutter moves rapidly for high productivity, then the door opening/closing speed is improved, but the safety risk increases due to user inability to monitor shutter position
Solution Approach 1:
The patent implements a feedback system using light-emitting elements (LEDs) that provide real-time visual information about the roller shutter's position and movement state. The system includes a control unit that receives signals from position sensors and activates appropriate light signals to indicate whether the shutter is moving or stationary, allowing users to safely interact with the door.
Solution Approach 2:
The patent introduces light-emitting elements as an intermediary communication medium between the shutter mechanism and the user. These visual signals act as a mediator that conveys the shutter's attitude (moving/stationary) without requiring direct visual monitoring of the physical shutter position, solving the safety issue while maintaining rapid operation.
2Productivity
If the roller shutter operates at high speed, then the efficiency is improved, but the user cannot immediately detect the shutter's movement state
Solution Approach 1:
The system continuously provides visual feedback through light-emitting elements that reflect the real-time movement state of the roller shutter. The control unit processes position information and generates appropriate light signals (first light signal for moving state, second light signal for stationary state), ensuring users have immediate awareness of the shutter's attitude without slowing down operation.
Solution Approach 2:
The patent employs different light signals (potentially different colors or patterns) to indicate different shutter states. This visual differentiation allows users to immediately comprehend the shutter's attitude through color or light pattern changes, maintaining high-speed operation while preventing information loss.
3Device complexity
If simple operating members are used, then the device complexity is reduced, but the ability to provide clear visual signals is limited
Solution Approach 1:
The operating member is designed as a multi-functional unit that combines the control function (button or switch for opening/closing) with the visual signaling function (incorporating light-emitting elements). This integration allows a single simple component to perform both control and information display, reducing overall device complexity while maintaining clear communication of shutter status.

AI summary
A device for controlling movement of a vertically sliding roller shutter door including a portal structure with uprights having guide rails for sliding a roller shutter for closing the door and a shelter zone for the roller shutter in the open condition delimited by an upper crosspiece, comprises motorized controllers for controlling movement of the roller shutter which are controlled by at least one operating member that generates an actuating signal for the motorized controller. The operating member includes an emitter indicative of an instantaneous setting of the roller shutter, and the device comprises a control unit connected to the operating member, to the emitter of signals of the operating members, to the motorized controller and to detector of the instantaneous attitude of the rolling shutter, to actuate the motorized controller and to emit a signal correlated with the instantaneous attitude of the roller shutter through the operating member.
