Fixing assembly for roller shade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller shade fixing assemblies are difficult to install and adjust, often resulting in skewed roller tubes and light leakage due to uneven installation frames.
Innovation Solution
A fixing assembly with a snap-fitting member and support system that allows for easy installation and adjustment, featuring a connecting portion and snap-fitting portion with an elastic plate and guiding slope, enabling horizontal alignment of the roller tube and reducing light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional installation frames with snap-fitting members are used to fix the roller tube, then the roller shade can be installed, but it is difficult to align the roller tube with the installation frames and the roller tube cannot be adjusted after installation
Solution Approach 1:
The installation frame is divided into a fixed portion and a movable adjusting portion that can slide along the fixed portion. This segmentation allows the roller tube position to be adjusted independently while maintaining the overall structure's stability and ease of installation.
Solution Approach 2:
The adjusting portion is designed to be movable relative to the fixed portion during installation, allowing position adjustment. After positioning, the snap-fitting mechanism locks the adjusting portion in place, transitioning from a dynamic state to a fixed state.
2Productivity
If installation frames are fixed at different heights due to worker skill or wall unevenness, then installation can be completed, but the roller tube becomes skewed and not horizontal
Solution Approach 1:
The adjusting portion can move vertically along the fixed portion to compensate for height differences. This dynamic adjustment capability allows installers to quickly level the roller tube without requiring precise initial positioning of both frames.
Solution Approach 2:
The snap-fitting mechanism automatically locks the adjusting portion at the correct position once the roller tube is leveled, providing self-aligning functionality that ensures horizontal installation without requiring additional adjustment tools or procedures.
3Ease of operation
If the roller tube is skewed due to uneven installation frames, then installation can be completed, but a gap is left between the top of the covering material and the architectural opening causing light leakage
Solution Approach 1:
The movable adjusting portion allows the roller tube to be positioned at the correct height to eliminate gaps. By sliding the adjusting portion vertically, the covering material can be properly aligned with the architectural opening, preventing light leakage while maintaining simple installation procedures.
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
Facilitates convenient installation and adjustment of roller shades, ensuring the roller tube remains horizontal and minimizing light leakage between the shade and the window opening.
Implementation Method 1
The snap-fitting portion includes an insertion block and an elastic plate, wherein the elastic plate is provided outside the insertion block along a pushing direction of the insertion block

AI summary
A fixing assembly is adapted to fix a main body of a roller shade to an environment, and is adapted to be installed at an end of a roller tube of the main body. The fixing assembly includes a fixing member, which corresponds to the roller tube when installed, and a fixing support corresponding to the fixing member. The fixing member includes a connecting portion and a snap-fitting portion connected to the connecting portion with an end thereof exposed out. The connecting portion can be connected to the end of the roller tube, whereby to fix the fixing member to the roller tube. The fixing support includes a fixing portion and a snap-fitted portion provided on a surface of the fixing portion facing the fixing member. The snap-fitting portion is detachably connected to the fixing support, and can be optionally engaged with the snap-fitted portion at different positions.
