Single Control Member for Shutter Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for motorized shutter devices, such as rolling shutters, require multiple button presses and user presence to achieve precise positioning, which can be time-consuming and restrictive, especially for larger or multiple shutters, due to sequential action requirements and limited control over speed.
Innovation Solution
A remote control device with a single control member that allows for instantaneous positioning of shutter devices through a coded position setpoint, processed into a control signal for automated opening and closing, featuring a movable control member with a touch zone and optional stop button, utilizing a microcontroller connected to incremental encoders or potentiometers for precise control and speed modulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple button presses and sequential actions are used for shutter control, then precise positioning can be achieved, but operation time increases and user presence is required
Solution Approach 1:
The control member is pre-positioned by the user to the desired shutter position before activation. This preliminary positioning action eliminates the need for sequential button presses during operation, as the target position is already determined. The system then executes the movement directly to this pre-set position, significantly reducing operation time while maintaining positioning precision.
Solution Approach 2:
The invention extracts the positioning function from the control sequence itself and separates it into a distinct preliminary action (positioning the control member) from the execution action (activating movement). This separation allows the user to determine the target position independently of the movement execution, eliminating the time-consuming sequential button pressing required in traditional systems.
2Adaptability or versatility
If traditional remote control with multiple buttons is used, then various control functions can be provided, but device complexity increases
Solution Approach 1:
The single control member serves multiple functions: it determines the target position, initiates movement, and can potentially indicate movement direction. By making this single element multi-functional, the invention maintains versatile control capabilities while eliminating the need for multiple separate buttons and control elements, thus reducing device complexity.
Solution Approach 2:
The invention merges the positioning function and the control activation function into a single integrated control member. Instead of requiring separate buttons for position selection and movement initiation, the control member combines these functions, allowing the user to set the desired position and trigger movement through a single unified interface.
3Measurement precision
If sequential button pressing is required for shutter control, then basic positioning can be achieved, but ease of operation deteriorates
Solution Approach 1:
The user performs the positioning action in advance by setting the control member to the desired position before activating movement. This preliminary action simplifies the operation sequence from multiple sequential button presses to a single intuitive gesture, significantly improving ease of operation while maintaining the ability to achieve precise positioning.
Solution Approach 2:
The control system automatically executes the movement to the position indicated by the control member without requiring further user input or correction. The system serves itself by interpreting the control member position and autonomously navigating the shutter to the target position, eliminating the need for users to manually guide the shutter through sequential commands.
