Innovation Solution
A reel pipe motor with a speed reduction assembly, charge control circuit, and bead switch system that allows for convenient power control and backup battery operation, combined with sensing elements for precise curtain control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rolling curtain is controlled by calculating the number of turns of the roller, then the positioning can be controlled, but the positioning accuracy deteriorates due to flexibility of the curtain and circumstantial factors
Solution Approach 1:
The patent applies feedback by using a sensor to detect the actual position of the rolling curtain and comparing it with the target position. The system automatically adjusts the motor operation based on the detected position feedback, ensuring accurate positioning despite curtain flexibility and external factors. The control system continuously monitors and corrects positioning errors in real-time.
2Extent of automation
If the reel pipe motor is controlled by general power supply switching, then the motor can be turned on or off, but the convenience of operation deteriorates
Solution Approach 1:
The patent applies self-service by enabling the motor to automatically manage its own power state. The motor controller automatically switches between charged power and battery power based on power availability, and automatically stops the motor when the curtain reaches the desired position or when power is cut off, eliminating the need for manual power switching operations.
3Power
If the rolling curtain requires external power supply to operate, then the motor can be powered, but the adaptability deteriorates when power is cut off
Solution Approach 1:
The patent applies preliminary action by pre-charging a battery within the motor housing during periods when external power is available. This stored energy is prepared in advance to ensure continuous operation during power outages. The system automatically switches to battery power when external power is cut off, maintaining operational adaptability without requiring external power throughout.
