Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunshade devices for outdoor structures like sunbeds are laborious to adjust and lack versatility, making them impractical for use on different types of furniture such as deck-chairs and recliners.
Innovation Solution
A sunshade device with telescopic upright elements and longitudinal elements that can be extended or retracted, allowing for adjustable shade projection and compact storage, featuring articulation systems for height and angle adjustments, enabling easy mounting on various structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sunshade device uses fixed non-adjustable elements, then the structure is simple and inexpensive, but the adaptability to different furniture types and adjustability of shade extent is poor
Solution Approach 1:
The patent applies telescopic elements that can extend and retract, transforming the static structure into a dynamic one. This allows the sunshade device to adapt to different furniture types (sunbeds, deck-chairs, recliners) by adjusting the length of the supporting elements, while maintaining a relatively simple overall structure that does not require completely different designs for each furniture type.
Solution Approach 2:
The sunshade device is designed with universal mounting capabilities that can accommodate multiple types of furniture structures. The supporting elements can be configured to work with sunbeds, deck-chairs, and recliners, making the device multi-functional and adaptable to different uses without requiring specialized designs for each furniture type.
2Ease of operation
If a sunshade device uses adjustable telescopic elements and canvas unrolling mechanisms, then the adaptability and ease of operation improve, but the device complexity increases
Solution Approach 1:
The telescopic elements are designed with nested structures where one element fits inside another, allowing for compact storage when not in use and easy extension when needed. This nesting principle simplifies the adjustment process while maintaining adaptability, as the elements can be quickly extended or retracted without complex assembly or disassembly procedures.
Solution Approach 2:
The dynamic telescopic mechanism allows users to easily adjust the shade extent by simply extending or retracting the elements, providing intuitive and simple operation. The canvas unrolling mechanism works in conjunction with the telescopic elements, automatically deploying the canvas as the elements extend, which simplifies the user interaction while achieving the desired adaptability.
3Area of moving object
If the sunshade device uses extendable longitudinal elements for larger shade projection, then the useful area increases, but the volume occupied when not in use increases
Solution Approach 1:
The telescopic longitudinal elements are designed to nest within each other when retracted, significantly reducing the volume occupied by the device when not in use. When extended, these same elements provide the necessary length to project a large shade area, thus resolving the contradiction between maximizing useful area and minimizing storage volume.
Solution Approach 2:
The dynamic nature of the telescopic elements allows them to transition between compact and extended states. This dynamic transformation enables the device to occupy minimal space during storage while providing extensive shade projection area during use, effectively resolving the volume-area contradiction.

AI summary
A sunshade device (1) prearranged for being mounted on a sunbed or the like, comprises: - a supporting structure (7), prearranged for anchorage of the sunshade device (1) on a structure of the sunbed or the like; and - a sunshade structure (8) associated at the top to the supporting structure (7), wherein the supporting structure (7) comprises at least two upright elements (9, 9') each having a lower end portion, prearranged for anchorage of the supporting structure (7) on the structure of the sunbed or the like, and an upper end portion, prearranged for carrying the sunshade structure (8). The sunshade structure (8) comprises two longitudinal elements (29, 30) which, in the condition of use of the sunshade device (1), extend in the direction of length of the sunbed or the like, and a canvas or the like (31), which is supported by means of the two longitudinal elements (29, 30). The two longitudinal elements (29, 30) are of a telescopic or extensible/retractable type, and the sunshade structure (8) has associated thereto, or is configured to provide, an arrangement (52) for unrolling/stretching out and rolling up/compacting the canvas or the like (31), in such a way that the sunshade structure (8) can be extended or retracted in the direction of the length of the sunbed or the like.
