Adjustable Motor Mounting for Roll-Up Shutter Anti-Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for fixing motor bodies to roll-up shutters are not versatile and require custom anti-rotation systems for different sizes and shapes, leading to impractical installation and replacement processes.
Innovation Solution
A system with a support having a slit for a removable pin that can be adjusted to various positions, allowing for easy configuration without the need for drilling holes, using fixing means like screws or quick release systems to constrain the pin, enabling adjustment to different motor sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated anti-rotation system is designed for each roll-up shutter size, then the motor can be securely fixed without undesired movements, but the device complexity increases and versatility decreases
Solution Approach 1:
The support structure is designed with a universal adjustment mechanism that can accommodate multiple motor sizes and roll-up shutter dimensions. The anti-rotation pin can be positioned at different locations along the support, allowing a single support design to serve multiple configuration needs rather than requiring dedicated anti-rotation systems for each shutter size.
Solution Approach 2:
The support structure incorporates adjustable elements that allow the anti-rotation pin position to be dynamically changed based on the specific motor and shutter combination. This adjustability enables the same support to adapt to different configurations while maintaining secure fixation, resolving the contradiction between reliability and versatility.
2Reliability
If custom anti-rotation systems are manufactured for different motor sizes, then proper motor fixation is achieved, but the ease of manufacture decreases and production costs increase
Solution Approach 1:
A single universal support design with adjustable pin positioning replaces the need to manufacture multiple custom anti-rotation systems for different motor sizes. This standardization simplifies the manufacturing process while maintaining the reliability of motor fixation across various applications.
Solution Approach 2:
The anti-rotation function is segmented from the motor itself and transferred to a separate adjustable pin mechanism on the support. This allows the support to be manufactured as a standard component that can work with different motors, improving ease of manufacture while maintaining fixation stability.
3Reliability
If drilling holes is required to fix the anti-rotation plate, then secure motor mounting is achieved, but the ease of operation decreases and installation time increases
Solution Approach 1:
The support structure is pre-designed with predetermined locations for the anti-rotation pin along its length, eliminating the need for drilling holes during installation. The pin can be directly positioned and secured at the appropriate location based on the motor size, significantly simplifying the installation process while maintaining mounting security.
Solution Approach 2:
The drilling operation is extracted from the installation process by using a support structure that already has the anti-rotation pin positioned on its surface. This allows the pin to be attached without penetrating the support, removing the need for drilling holes and making installation much more convenient.

AI summary
A system (10) to fix a motor body (4) to a roll-up shutter (1), for allowing at least one blade (3) of the roll-up shutter (1) to be moved. The roll-up shutter (1) comprises a frame (2), which is associated with at least one blade (3), which is mobile relative to the frame (2). The system (10) comprises a support (12), which is adapted to be associated with the frame (2) of the roll-up shutter (1). The support (12) has at least one slit (14), in which at least one pin (16) slides, which can be constrained in any position of the slit (14); the pin (16) being adapted to be associated with a the motor body (4), thus locking it to the frame (2).
