Modern Curtain Driving Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tubular motors in electric-driven roller blinds have a small diameter, limiting the space for electric elements and intelligent chips, leading to increased costs, safety risks, and compatibility issues with short curtains and potential signal interference.
Innovation Solution
A modern curtain driving device with a power module, control module, and tubular motor arranged separately, where the power module and control module are placed on a horizontal part and the tubular motor on a vertical part, allowing for larger mounting space, improved signal strength, and flexibility in accommodating both long and short roller blinds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tubular motor diameter is reduced to match small roller tubes, then convenience in mounting is improved, but the space for electric elements and intelligent chips is insufficient
Solution Approach 1:
The patent divides the motor system into two separate components: a compact tubular motor for mounting convenience and a separate power supply module with sufficient space for electric elements and intelligent chips. This segmentation allows each component to be optimized independently, resolving the contradiction between small motor diameter and adequate space for electronics.
2Extent of automation
If the tubular motor length is prolonged to accommodate more chips, then intelligentized development is improved, but the suitability for short curtains is reduced
Solution Approach 1:
The patent extracts the power supply module containing intelligent chips from the tubular motor structure. This allows the motor to maintain its original compact length suitable for short curtains, while the separate power supply module provides adequate space for intelligentized chips and can be installed independently on the roller blind structure.
3Strength
If the outer tube is made of metal for structural strength, then mechanical strength is improved, but signal interference to intelligent chips is caused
Solution Approach 1:
The patent introduces a non-metallic outer tube (plastic or aluminum alloy) as an intermediary material that provides sufficient structural strength while being electrically non-conductive. This material choice eliminates signal interference to intelligent chips while maintaining the necessary mechanical strength for supporting the roller blind structure.

AI summary
A modern curtain driving device is provided which comprises a power module, a control module and a tubular motor, wherein it further comprises a connecting terminal seat; the connecting terminal seat comprises a vertical part, and a horizontal part; the horizontal part comprises an accommodating cavity for installing the power module and the control module; and the tubular motor is installed on the vertical part and is parallel to the horizontal part. Additionally, being separated from the tubular motor, the control module is more stable for receiving signals and the separated arrangement of the tubular motor from the power module and the control module, the tubular motor is diverse in length design, and thus more suitable for both long and short roller blinds.
