Rolling Assembly for Electric Roller Shutter Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric roller shutters consume excessive power due to reliance on driving motors for both upward and downward movements, lacking an efficient mechanism to reduce energy usage specifically for upward rolling.
Innovation Solution
An energy-saving apparatus comprising a curtain unit with a driving shaft, a fixing unit with a rolling assembly, and a signal receiver, where the rolling assembly reduces power consumption by facilitating upward rolling through a DC motor-driven system with a rotary connecting portion and a reed mechanism, minimizing motor operation.

Engineering Contradiction Analysis
1Extent of automation
If a driving motor is used to move the electric curtain both upward and downward, then the curtain can be automatically controlled, but power consumption increases
Solution Approach 1:
The curtain movement system is segmented into two independent mechanisms: a driving motor for downward movement and a rolling assembly for upward movement. This segmentation allows each component to perform its specific function efficiently, with the rolling assembly utilizing spring energy storage to reduce motor power consumption during upward operation.
Solution Approach 2:
The spring is pre-loaded with energy during the downward movement phase, storing potential energy that is then released to assist upward movement. This preliminary action of energy storage eliminates the need for continuous high-power motor operation, significantly reducing overall power consumption.
2Use of energy by moving object
If a control rope is used to manually roll the curtain, then power consumption is minimized, but safety hazards arise from winded ropes
Solution Approach 1:
The hazardous control rope is completely removed from the system and replaced with an automatic driving mechanism. The driving motor and rolling assembly work together to provide automated curtain operation, eliminating the safety hazard of winded ropes while maintaining energy efficiency through the spring-assisted rolling mechanism.
Solution Approach 2:
The manual mechanical control rope system is replaced with an automated electromechanical system comprising a driving motor, transmission mechanism, and spring-assisted rolling assembly. This substitution eliminates safety hazards associated with manual rope operation while providing automated control.

AI summary
An energy saving apparatus for an electric roller shutter contains a curtain unit, a fixing unit, a signal receiver, and a controller. The curtain unit includes a driving shaft having a chamber and a rotary connecting portion, and the curtain unit also includes a driver and a curtain. The fixing unit is configured to fix the curtain unit and includes a mounting rack, a first seat, a second seat, and a rolling assembly which reduces power consumption of the driver and facilitates an upward rolling of the curtain, when the curtain rolls. The signal receiver is electrically connected with the driver and includes a casing, a coupling portion, a power supply module, and a receiving module. The controller is configured to send a signal to the receiving module in the casing of the signal receiver, such that the driver of the curtain unit is controlled by the controller to operate.
