Self-Adjusting Sun Shade Assembly for Wind Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beach umbrellas lack stability in windy conditions, frequently shifting position and prone to tipping over, requiring manual adjustment and posing a risk of injury or damage.
Innovation Solution
A self-adjusting sun shade assembly with a pivot cap, ribs, support arms, and a mast system that allows the assembly to rotate and adjust in response to wind, featuring a tension adjuster to control rotation, ensuring stability and preventing tipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional single central support pole is used, then the umbrella structure is simple, but the stability in windy conditions deteriorates
Solution Approach 1:
The single central support pole is segmented into multiple support poles (at least two) that are distributed around the canopy. This segmentation distributes the wind load across multiple points rather than concentrating it on a single pole, significantly improving stability in windy conditions while maintaining structural integrity.
Solution Approach 2:
Multiple support poles are combined with a common base structure and canopy system. The poles work together as a unified support system, sharing the mechanical loads and providing mutual reinforcement against wind forces, thereby achieving enhanced stability without excessive complexity.
2Stability of the object's composition
If the umbrella is fixed in position, then the structure is stable, but the ability to self-adjust to wind direction deteriorates
Solution Approach 1:
The umbrella structure incorporates dynamic elements that allow controlled movement and rotation of the support poles and canopy assembly. This enables the umbrella to self-adjust its orientation in response to changing wind directions while maintaining operational stability, resolving the contradiction between fixed position and adaptive capability.
3Ease of operation
If manual adjustment is required frequently, then the structure can be repositioned, but the ease of operation deteriorates
Solution Approach 1:
The umbrella system incorporates self-adjusting mechanisms that automatically respond to wind forces without requiring manual intervention. The structure uses passive mechanical elements such as tensioning systems and rotational joints that automatically reposition the canopy and support poles in response to wind direction changes, eliminating the need for frequent manual adjustment and saving user time.

AI summary
The presently disclosed subject matter is directed to a sun shade assembly. Particularly, the assembly includes a sail that releasably attaches to a pair of ribs, providing shade to the user. At least one support arm can be used to reinforce the ribs. A mast provides height to the assembly and includes an anchor that allows the assembly to be secured into a support surface (e.g., sand). The ribs and support arms rotate about the mast, thereby self-adjusting the direction of sail in response to the wind blowing. The assembly further includes a tension adjuster that can be tightened or loosed to control the rotation of the ribs and support arms in response to wind conditions.
