Solar Panel Mounted on Roller Shade Back Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar electric curtains face conflicts between photovoltaic function and curtain retraction/retraction processes, and require significant space for installation, as the solar panel's ability to generate energy is hindered when the curtain is retracted and large space is needed for support frames.
Innovation Solution
A solar electric roller shade design where the solar panel is externally disposed on the back surface of the roller shade body, independent of the roller shade, allowing continuous energy absorption without occupying additional space, with a fixed support member using L-shaped angle steels and a telescopic rod for adjustable height, and a compact configuration of the speed reduction motor and battery within the cross beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the solar film product is disposed on the curtain cloth, then the solar film can absorb light energy, but the solar film cannot obtain energy when the curtain is in a retracted state
Solution Approach 1:
The patent divides the system into two independent parts: the solar panel is separated from the curtain cloth and mounted on the roller shade body instead. This segmentation allows the solar panel to remain stationary and functional while the curtain operates independently, resolving the conflict between energy absorption and curtain retraction operations.
Solution Approach 2:
The solar panel is mounted on the back surface of the roller shade body, utilizing the spatial dimension of the roller shade structure rather than being integrated with the curtain cloth. This dimensional repositioning enables the solar panel to maintain its light-receiving function while the curtain performs its retraction and releasing operations.
2Use of energy by moving object
If a solar panel is erected on a courtyard or roof, then electric energy can be obtained for the electric curtain, but sufficient installation site is required with high space occupation rate
Solution Approach 1:
The patent merges the solar panel mounting function with the existing roller shade body structure. By utilizing the back surface of the roller shade body as the mounting location, the system combines two functions (curtain operation and solar energy generation) into a single integrated structure, eliminating the need for separate support frames and reducing overall space occupation.
Solution Approach 2:
The roller shade body serves multiple functions: it provides the curtain retraction mechanism and simultaneously serves as the mounting structure for the solar panel. This multi-functionality eliminates the need for dedicated solar panel support structures, thereby reducing the space required for installation while maintaining both curtain operation and solar energy generation capabilities.
