Spring Roller Blind Auxiliary Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spring roller blind systems have inconvenient and time-consuming adjustments for the height and winding modules due to the small outer diameter of the adjusting shafts and perpendicular rotation axes, requiring multiple turns for adjustments.
Innovation Solution
The spring roller blind system incorporates an auxiliary adjusting element with a handle and engaging member that aligns with the main adjusting elements, allowing parallel rotation axes and fewer turns for adjustments, along with a fixing element to secure the second main adjusting element, facilitating easier operation and faster adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand tool is used to adjust the height adjusting module or winding module through the slot in the adjusting shaft, then the adjustment can be performed, but the adjustment process becomes inconvenient and time-consuming due to the small outer diameter of the adjusting shaft and perpendicular rotation axes requiring multiple turns
Solution Approach 1:
An auxiliary adjusting element is introduced as an intermediary tool that engages with the adjusting shaft. This auxiliary element has a larger outer diameter than the original adjusting shaft, providing a better grip for hand tools and enabling more efficient torque transmission during adjustment operations, thereby reducing adjustment time and improving convenience
Solution Approach 2:
The rotation axis orientation is changed from perpendicular to parallel alignment between the adjusting shaft and the roller tube. This parameter change allows for direct rotational transmission with fewer turns required, significantly reducing adjustment time and improving operational efficiency
2Volume of moving object
If the adjusting shaft has a small outer diameter and perpendicular rotation axis, then the device structure remains compact, but multiple turns are required for adjustment making the process time-consuming
Solution Approach 1:
The auxiliary adjusting element serves as a mediator that bridges the compact adjusting shaft and the hand tool. It maintains the compact device structure while providing a larger engagement surface for the hand tool, enabling faster adjustment speed without compromising device compactness
Solution Approach 2:
Changing the rotation axis from perpendicular to parallel orientation optimizes the mechanical transmission path. This allows for more direct force transmission and reduces the number of turns needed, thereby increasing adjustment speed while maintaining a relatively compact device structure
3Device complexity
If the adjusting shaft rotates multiple circles to drive the adjusting member, then the perpendicular axis configuration is maintained, but the adjustment becomes inconvenient and time-consuming
Solution Approach 1:
The rotation axis orientation parameter is changed from perpendicular to parallel configuration. This simple parameter change fundamentally improves adjustment ease by reducing the number of turns required, while actually simplifying rather than complicating the rotation mechanism through more direct force transmission

AI summary
A spring roller blind system is provided that has a roller blind module, a height adjusting module, a winding module, a first main adjusting device disposed on the height adjusting module, a second main adjusting device disposed on the winding module, an auxiliary adjusting element, and a fixing element. The height adjusting module and the winding module are respectively disposed on two ends of the roller blind module. The auxiliary adjusting element is selectively and detachably disposed on a first main adjusting element of the first main adjusting device or a second main adjusting element of the second main adjusting device for adjusting the height adjusting module or the winding module. The fixing element is selectively inserted into a fixing recess of the winding module for positioning the second main adjusting element.
