Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunshade devices face challenges in ensuring accurate motor rotation during automatic rolling up and unrolling of curtains after manual intervention, which can lead to motor damage and incomplete rolling or unrolling.
Innovation Solution
A manual automatic integrated sunshade panel that utilizes a sensor to record the rotation stroke of the motor's shaft, allowing the motor to accurately control the curtain's stroke, featuring a motor, power storage mechanism, reel, and main control module, with the sensor and motor connected to the main control module to ensure complete rolling up and unrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pulling of the curtain is allowed, then ease of operation is improved, but measurement precision of motor rotation stroke deteriorates
Solution Approach 1:
The patent employs a sensor to detect the rotation stroke of the motor shaft and feeds this information back to the control module. When the user manually pulls the curtain, the sensor records the actual rotation distance, and the control module uses this feedback to calculate and adjust the required motor rotation for complete rolling up or unrolling, ensuring precise control despite manual intervention.
2Productivity
If the motor rotates without accurate stroke control, then productivity is improved, but reliability of the motor deteriorates
Solution Approach 1:
The control module receives real-time feedback from the sensor about the motor shaft's rotation stroke and uses this information to precisely control the motor's rotation. This feedback mechanism ensures the motor rotates exactly the required distance for complete curtain rolling up or unrolling, preventing over-rotation that could damage the motor while maintaining efficient operation.
3Ease of operation
If the curtain is not fully rolled up or unrolled, then ease of operation is improved, but manufacturing precision of curtain positioning deteriorates
Solution Approach 1:
The sensor continuously monitors the motor shaft's rotation stroke and provides feedback to the control module. Based on this feedback, the control module calculates the exact rotation needed to achieve complete rolling up or unrolling from any intermediate position, ensuring the curtain reaches its intended final position with high precision regardless of where manual intervention occurred.
