Canopy Awning with Dual Rollers for Rainwater Runoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canopies with awnings face issues such as rainwater runoff interference, sagging and pooling of awnings, space requirements for storing folded awnings, and the need for multiple profiles and stock sizes, which increase costs and complexity.
Innovation Solution
A canopy design with a load-bearing structure featuring at least four beams, where a first roller in the first beam is used for a horizontal awning, and a second roller for a vertical awning, with guides connecting the end bars between beams to allow both horizontal and vertical awnings to roll out and up, optimizing space and preventing pooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a horizontal roll-up awning is incorporated in one of the four beams with a separate screen casing, then the awning can be stored, but the space between the posts under that beam cannot be covered by a vertical awning and the structure becomes more complex
Solution Approach 1:
The patent combines the horizontal and vertical awning functions into a single integrated beam structure. The first beam contains both a first roller for horizontal awning and a second roller for vertical awning, eliminating the need for a separate screen casing and enabling comprehensive coverage of both horizontal and vertical openings.
Solution Approach 2:
The first beam is designed to perform multiple functions: it houses both the horizontal awning mechanism (first roller) and the vertical awning mechanism (second roller), making it a multi-functional component that provides both horizontal and vertical coverage capabilities.
2Ease of manufacture
If the awning is made flat when fully extended, then it is easy to manufacture, but it interferes with rainwater runoff and causes pooling
Solution Approach 1:
The patent applies a pitch (inclination) to the awning surface instead of keeping it completely flat. This curvature/inclination is achieved through the guides extending at a pitch relative to the horizontal, allowing rainwater to run off effectively while maintaining manufacturability.
3Volume of moving object
If the folded pack of the awning is stored in the opening, then it is compact, but it requires significant space and beam height
Solution Approach 1:
The patent nests the folded awning pack within the beam structure itself. The guides and rollers are integrated into the beam, and the folded awning is contained within the beam's internal space, optimizing the use of available space and reducing the required beam height.

AI summary
Canopy with awning, whereby the canopy (1) comprises a load-bearing structure (2) with at least four beams (3A,3B,3C,3D), whereby in at least a first beam (3A) a first roller (9A) is provided to which a first awning (6A) is attached and whereby at the facing end of the first awning (6A) a first end bar (7) is provided, the ends of which are guided using guides (8) provided on or in a second beam (3B) and a third beam (3C), said guides (8) guiding the first end bar (7) from the first beam (3A) to a facing fourth beam (3D) and whereby in the first beam (3A) a second roller (9B) is provided to which a second awning (6B) is attached and whereby on the facing end a second end bar (7) is provided which rolls out from the first beam (3A) toward the ground.
