Universal Geared Motor Unit for Screening Blind Drive Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motorized-drive devices for different types of blinds lack streamlining, resulting in high costs due to the use of specific motor means for each application, which complicates the management of component parts and hinders configurability across various screen types.
Innovation Solution
A range of motorized-drive devices sharing an identical geared motor unit model, with adaptable speed reduction or overdrive stages and electronic control modules, allowing for shared components and simplified design suitable for multiple blind types, including pleated, cellular, Roman, and Venetian blinds, as well as windable screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different motor means are used for each blind application, then the speed, torque and noise level requirements are met, but the device complexity and cost increase
Solution Approach 1:
The patent implements a universal motorized-drive device with a shared geared motor unit model that can be configured for different blind applications through variable parameters (speed ratio, torque, noise level) rather than requiring separate motor designs for each application type
2Reliability
If application-specific motor means are used, then targeted response to speed, torque and noise level requirements is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent creates a universal motorized-drive device platform that serves multiple blind applications through configurable parameters, eliminating the need for separate production lines and inventory management for different motor types, thereby reducing manufacturing costs while maintaining application-specific performance
3Reliability
If multiple types of drive devices are maintained, then specific blind requirements are met, but the streamlining of component parts is hindered
Solution Approach 1:
The patent implements a dynamic configuration system where the geared motor unit parameters (speed ratio, torque output, noise level characteristics) can be varied to match different blind applications, allowing a single device platform to adapt to multiple requirements without sacrificing optimization for any specific application

AI summary
A range of motorized-drive devices (100, 200, 300) for screening blinds comprises: at least one first drive device (100) for driving a first screening blind, comprising a first support (102), a first shaft (104) rotating about a first axis of revolution (106) with respect to the first support (102), at least a winding drum (108) for winding a drive cord of the first screening blind, rotating as one with the first shaft (104), a first geared motor unit (110) for driving the first shaft (104), housed in the first support (102) and kinematically connected to the first shaft (104), preferably via an overdrive (112), and a first electronic control module (114) fixed remote from the first geared motor unit (110), and at least one second drive device (200) for driving a second screening blind, comprising a second support (202), a winding tube (204) for the second screening blind mounted in the second support (202) so as to rotate about a second axis of revolution (206) with respect to the second support (202), a second geared motor unit (210) for driving the winding tube (204), housed inside the winding tube (204), and a second electronic control module (214) fixed remote from the second geared motor unit (210). The first geared motor unit (110) and the second geared motor unit (210) are identical and define a model of geared motor unit (10) that is common to the motorized-drive devices (110, 210) of the range.
