Adjustable Roller Blind Support Device with Depth-Setting Lugs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional roller shutter installation requires complex on-site assembly and adjustment, with limited depth adjustment capabilities, making it challenging to accommodate varying configurations and reducing efficiency due to the need for multiple parts and specialized labor.
Innovation Solution
A support device with adjustable flange assembly means and complementary assembly means on the lug, allowing for depth adjustment of the shaft position relative to the slides, enabling pre-assembled units to be easily installed on-site with reduced assembly operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed flange assembly is used, then结构简单 (structure is simple), but 深度调节能力不足 (depth adjustment capability is insufficient)
Solution Approach 1:
The flange assembly is designed with adjustable depth capability through the interaction between lugs and notches. The lugs can be positioned at different depths by engaging with notches at various positions on the support legs, allowing the assembly structure to adapt dynamically to different installation requirements while maintaining a relatively simple overall design.
Solution Approach 2:
The flange assembly is divided into separate components: flanges, lugs, and support legs with notches. This segmentation allows each component to be independently manufactured and assembled, providing depth adjustment capability without significantly increasing the complexity of the overall structure. The modular design enables flexible configuration for different installation scenarios.
2Productivity
If pre-assembly in workshop is increased, then 现场组装零件数量减少 (number of parts to assemble on site is reduced), but 现场调节深度能力受限 (on-site depth adjustment capability is limited)
Solution Approach 1:
The roller shutter assembly including the shaft, apron, and flanges is pre-assembled in the workshop as a complete unit. This preliminary assembly reduces the number of parts that need to be handled and assembled on-site, improving installation efficiency. The pre-assembled unit is designed with integrated depth adjustment capability through the lug-notch mechanism, allowing final configuration adjustments to be made on-site without requiring complex disassembly and reassembly operations.
3Adaptability or versatility
If multiple series of notches are provided, then 深度调节可能性增加 (depth adjustment possibilities are increased), but 制造复杂度增加 (manufacturing complexity increases)
Solution Approach 1:
The depth adjustment mechanism is segmented into multiple discrete notch positions on each support leg. Each notch represents a predetermined depth position, and multiple notches provide a range of adjustment options. This segmentation approach allows for increased adaptability while keeping manufacturing straightforward, as notches can be easily formed or drilled at specific positions during production without requiring complex machining operations.

AI summary
Support device for a roller blind which comprises a blind (B) rolled on a shaft (1), comprising an endplate (2) at each end of the shaft, it being possible for the blind to be unrolled, once it has been installed in a box or a space at the top of an opening equipped with slideways (5) on its sides for guiding the blind. An assembly means (A1) is provided on each endplate to collaborate with a complementary assembly means (A2) provided on a lug (6) that can be engaged in the top of the slideway (5) to support the shaft (1) via the endplates, the assembly means allowing depthwise adjustment of the position of the shaft (1) relative to the slideways (5). A factory pre-fitted assembly consisting at least of the blind (B) wound onto a shaft (1) mounted between the endplates (2) may be installed on site by assembling the endplates (2) and the lugs (6) with depthwise adjustment of the position of the shaft and of the roller blind as a whole.
