Solution Overview
Problem
Existing motorized screen maneuvering devices for windable fabric screens are complex, require additional accessories, and are not versatile enough to suit different home automation system architectures, particularly in conventional and inverse-mounted configurations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the actuator is mounted inside the winding tube with conventional accessories, then the maneuvering function is achieved, but the device complexity increases and the architecture becomes less versatile
Solution Approach 1:
The end-plate integrates multiple functions: it closes the actuator housing, provides mounting surfaces for the winding tube, incorporates rotation stopping elements, and serves as a structural support. This merging of functions into a single component reduces the number of separate accessories needed while maintaining adaptability to different mounting configurations.
Solution Approach 2:
The end-plate design with its multiple supports and rotation stopping elements creates a universal mounting solution that can accommodate both conventional mounting configurations (where the winding shaft is fixed to the frame) and inverse-mounted configurations (where the winding shaft is suspended on the fabric). The same end-plate structure serves different architectural needs.
2Reliability
If additional accessories are used to mount the actuator, then the actuator can be fixed, but the device architecture becomes more complex
Solution Approach 1:
The mounting function is merged into the end-plate itself. The end-plate provides integral mounting surfaces and connection points, eliminating the need for separate mounting accessories. The first and second supports extend from the end-plate to provide stable fixation, while rotation stopping elements prevent unwanted movement, all as part of the single end-plate component.
3Adaptability or versatility
If the winding shaft is kept in a fixed position relative to the frame, then the conventional mounting is achieved, but the device cannot adapt to inverse-mounted configurations
Solution Approach 1:
The end-plate with its first support (for rotational connection) and second support (for structural mounting) creates a universal interface that works for both conventional mounting (winding shaft fixed to frame) and inverse-mounted configurations (winding shaft suspended on fabric). The same hardware architecture supports different operational modes without requiring additional accessories or design modifications.

Function Achieved in This Case
The solution provides a simple, reliable, and versatile motorized screen maneuvering system that can be used in various configurations, reducing complexity and enhancing operational efficiency by integrating the actuator and supporting elements within a single piece, thus minimizing thickness and maximizing fabric winding proximity to the end-plate.
Implementation Method 1
an actuator, comprising a hollow housing containing a gear motor
Implementation Method 2
The weight of the manoeuvring device creates a fabric unwinding torque. The device comprises an unwinding torque neutralizing means that acts exclusively by interaction with gravity and/or with the fabric.
