Spring roller shutter with adjustable function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional spring roller shutters lack adjustable functionality, leading to incomplete curtain withdrawal, exposing window frames, causing noise and aesthetics issues, and being impractical for varying window configurations.
Innovation Solution
A spring roller shutter design incorporating a concentric adjusting cylinder, limiting assembly, and telescopic rod system allows for adjustable maximum withdrawal height and width, enabling customizable curtain positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the curtain is completely rolled up to the roller, then the curtain structure is simple and the operating mechanism is simple, but the window frames are exposed affecting aesthetics and generating noise, and the curtain cannot be adjusted to different heights
Solution Approach 1:
The patent implements a nested structure where the adjusting cylinder is concentrically arranged inside the drum, and the telescopic rod is arranged inside the adjusting cylinder. This nested design allows multiple functional components to occupy the same spatial envelope, enabling adjustable curtain withdrawal height without significantly increasing the overall device size or structural complexity.
Solution Approach 2:
The patent introduces dynamic adjustability through the telescopic rod and adjusting cylinder mechanism. The telescopic rod can extend and retract along the adjusting cylinder, allowing the curtain withdrawal height to be dynamically adjusted according to different window configurations and user needs, transforming a static system into a dynamic one.
2Adaptability or versatility
If the roller shutter is installed above window frames, then the installation position is flexible, but when the curtain is completely rolled up, the window frames are exposed and collision noise occurs
Solution Approach 1:
The patent enables dynamic control of curtain withdrawal height through the adjusting assembly and limiting assembly. Users can adjust the limiting screw to set the maximum withdrawal height, allowing the curtain to stop before reaching the window frame, thereby eliminating collision noise while maintaining installation flexibility above the window frames.
3Ease of operation
If the curtain is completely rolled up, then the curtain structure is simple, but the curtain may be out of reach or cannot shield sunlight at the upper end according to personalized requirements
Solution Approach 1:
The patent provides dynamic adjustability of curtain withdrawal height through the telescopic rod mechanism. Users can adjust the limiting assembly to set the maximum withdrawal height to a reachable level, making the curtain accessible while still able to shield sunlight at the upper end according to personalized requirements.
Solution Approach 2:
The patent changes the parameter of curtain withdrawal height from a fixed value to an adjustable range. By modifying the limiting screw position in the limiting assembly, users can change the maximum withdrawal height parameter to match different accessibility needs and sunlight shielding requirements.
