Curtain Roller With Magnetic Stop Part For Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing curtains on the market fail to effectively block direct light, which can be dazzling and negatively impact user experience.
Innovation Solution
A curtain roller system comprising a main body that rotates to wind or unwind the curtain, and a stop part that creates a stop space to prevent further rotation once the curtain is wound, allowing for adjustable light control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the curtain is designed to slide left and right to cover or expose windows, then the curtain can control light exposure, but direct light still enters through uncovered parts causing dazzling effect and poor user experience
Solution Approach 1:
Instead of the conventional side-sliding curtain mechanism, this patent inverts the approach by using a bottom-to-top rolling mechanism. The curtain roller is positioned at the bottom of the window and rolls upward to cover the window area, fundamentally changing the direction and method of curtain operation to effectively block direct light while maintaining ease of use through simple rotational motion
2Object-affected harmful factors
If the curtain roller rolls up the curtain from bottom to top, then direct light is blocked effectively, but the structure becomes more complex requiring a stop part to prevent over-rotation
Solution Approach 1:
The stop function is extracted as a separate, independent component (the stop part) that can be detachably connected to the roller mechanism. This stop part includes a stop tooth that engages with a corresponding groove on the roller, providing a simple and effective way to prevent over-rotation without complicating the overall structure. The detachable design allows for easy installation and maintenance
3Adaptability or versatility
If the stop part is detachably connected to the main body of roller, then the structure is more flexible and maintainable, but the connection mechanism becomes more complex
Solution Approach 1:
The connection mechanism is segmented into distinct components: a mounting hole in the roller body, a mounting shaft with a stop tooth in the stop part, and a corresponding groove on the roller. This segmentation allows for simple, modular assembly where the stop part can be easily attached and detached without complex fastening mechanisms, achieving both flexibility and simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The curtain roller system allows for efficient rolling up of curtains from the bottom to the top, blocking direct light while allowing indirect light to pass through, thereby enhancing user experience by adjusting light according to the angle of sunlight.
Implementation Method 1
the stop part is magnetically connected to the main body of roller; the stop part is equipped with a first magnetic attraction member, the main body of roller is equipped with a first magnetic attraction fitting member, and the first magnetic attraction member is magnetically connected to the first magnetic attraction fitting member

AI summary
A curtain roller includes a main body of roller and a stop part. The main body of roller is connected with a curtain, and the main body of roller is capable of rotating on a surface of the curtain to a winding position or an unfolding position. When the main body of roller rotates to the winding position, the main body of roller rolls up the curtain. When the main body of roller rotates to the unfolding position, the main body of roller unfolds the curtain. The stop part is connected to the main body of roller. A stop space is formed between the stop part and the main body of roller. When the main body of roller rotates to the winding position to roll up the curtain, and the curtain is positioned in the stop space, the main body of roller cannot rotate on the surface of the curtain.
