Angled Roller Blind Assembly With Horizontal Sheet Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller blinds are unable to fully fit and cover angled architectural openings, particularly when the angled side is at the top or bottom, as they are designed for rectangular shapes and can only extend vertically from the top-mounted roller.
Innovation Solution
A roller blind assembly comprising a frame, roller tube assembly, chain assembly, track assembly, extension assembly, actuator and clutch assembly, and motor assembly, which allows for horizontal extension and retraction, enabling full coverage of angled openings by adjusting the roller blind sheet's attachment points and using a motor-driven system to manage the sheet's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the roller blind is designed for rectangular openings with top-mounted roller and vertical extension, then it can properly extend and retract to fit rectangular openings, but it cannot fully fit and cover angled architectural openings
Solution Approach 1:
The roller blind system is divided into multiple independent components: a rectangular frame structure, an angled sheet element, a roller assembly, and a weighting system. This segmentation allows each component to perform its specific function - the frame provides structural support, the angled sheet covers the opening, and the weighting ensures proper extension - while collectively solving the problem of covering angled openings without requiring complete redesign of the entire blind system
Solution Approach 2:
The invention introduces an angled dimension to the traditionally vertical roller blind configuration. By positioning the roller at the top corner and extending the sheet element at an angle rather than strictly vertically downward, the system adapts to angled architectural openings while maintaining the fundamental top-mounted roller architecture
2Ease of operation
If the roller is mounted at the top side of the architectural opening, then gravity assists to extend the sheet element downward, but existing roller blinds cannot properly extend and retract to fit angled architectural openings
Solution Approach 1:
The invention employs asymmetric positioning of the roller at the top corner of the opening rather than centered at the top edge. This asymmetric placement, combined with the angled extension of the sheet element, allows the system to leverage gravity assistance while adapting to the asymmetric geometry of angled architectural openings
3Device complexity
If the sheet element is made of thin flexible material, then it can roll up around the roller, but the weight of the sheet element alone is insufficient to keep it extended over angled architectural openings
Solution Approach 1:
The invention introduces a weighting system that acts as a counterbalance to the thin flexible sheet element. The weight is positioned to provide sufficient force to keep the sheet element extended over the angled opening, compensating for the insufficient weight of the thin material itself while allowing the material to remain simple and flexible

AI summary
Implementations of a roller blind assembly for angled architectural openings are provided. In some implementations, the roller blind assembly comprises a frame, a roller tube assembly, a roller blind sheet, a chain assembly, a track assembly, an extension assembly, an actuator and clutch assembly, and a motor assembly. In some implementations, a method of using the roller blind assembly comprises installing the roller blind assembly to fully fit the perimeter of an angled architectural opening and operating the roller blind assembly to fully cover the opening of the angled architectural opening.
