Motorized Screen Group with Integrated Motor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motorized screen groups require significant time to move from a closed to an open position and are not easily assembled or maintained, with motors typically connected to the roller or uprights, limiting their efficiency and usability.
Innovation Solution
A motorized screen group where the motor controls the guiding means, such as a driven belt, to directly manage the movement of the screen, allowing for easier assembly and maintenance, and enabling the screen to be moved from a closed to an open position efficiently, with the motor being integral to the upright and not connected to the roller or uprights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the motor is connected to the roller or uprights for automatic screen movement, then the screen can be opened and closed automatically, but the assembly and maintenance become difficult
Solution Approach 1:
The system is divided into independent modular units: the motor unit integrated with the guiding means, and the screen unit with the roller. This segmentation allows the motor and guiding means to be assembled as one module and the screen as another, facilitating easier assembly and maintenance while preserving automatic movement capability.
Solution Approach 2:
The motor is extracted from the traditional connection to the roller or uprights and repositioned to control the guiding means directly. This extraction simplifies the mechanical connection requirements and makes the motor more accessible for maintenance while maintaining automated functionality.
2Extent of automation
If the motor is connected to the roller or uprights for automatic screen movement, then the screen can be opened and closed automatically, but the ease of operation is reduced
Solution Approach 1:
The guiding means acts as an intermediary between the motor and the screen. The motor controls the guiding means (such as a belt or chain), which in turn controls the screen movement. This intermediary system provides smoother operation and better control compared to direct motor-to-roller connection.
3Extent of automation
If traditional motor connections are used for screen groups, then automatic movement is achieved, but the device complexity increases
Solution Approach 1:
The motor and guiding means are merged into a single integrated unit. This combination reduces the number of separate components and connections required, simplifying the overall device structure while maintaining automatic screen movement capability.
