Sunshade Stabilizer Bar with Telescopic Rod and Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilizer bar units for oversized umbrellas and awnings are insufficient in withstanding high wind loads and often cause additional stress on the struts due to permanent bracing, leading to reduced fatigue strength.
Innovation Solution
A stabilizer bar assembly with an angle adjustment device and a bayonet-style plug-in connection that allows tool-free detachment and coupling, featuring a horizontal pivot axis and a cross pin that can be inserted into a T-nut, enabling the strut and rod to maintain different angles without tension, and a telescopic rod for universal fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stabilizer rod units are used to increase stability under wind loads, then the sun protection becomes extremely stable, but additional permanent load occurs on the strut which reduces fatigue strength
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed rigid connection with a telescopic rod assembly that can dynamically adjust its length. The rod includes a first rod section and a second rod section that can extend or retract relative to each other, allowing the stabilizer to adapt to varying wind conditions and reduce permanent loading on the strut while maintaining stability when needed.
Solution Approach 2:
The patent implements parameter changes by introducing adjustable geometric parameters into the stabilizer system. The telescopic rod allows change in the distance between the first and second connection parts, and the angle adjustment device enables variation in the angle between the rod and the strut. These parameter changes allow the system to optimize performance under different loading conditions, reducing fatigue stress on the strut.
2Device complexity
If fixed angle connection is used between rod and strut, then structural simplicity is maintained, but tension occurs between parts reducing adaptability
Solution Approach 1:
The angle adjustment device implements dynamics by replacing the fixed angle connection with a mechanism that allows the angle between the rod and strut to be adjusted. This dynamic adjustment capability enables the connection to adapt to different installation conditions and operational requirements without significantly increasing overall system complexity.
Solution Approach 2:
The connection structure is segmented into multiple adjustable components: the telescopic rod sections, the angle adjustment device, and the connection parts. This segmentation allows independent adjustment of length and angle parameters, providing versatility while keeping each individual component relatively simple in design.
3Reliability
If traditional fastening methods are used for stabilizer rods, then secure attachment is achieved, but tool-free quick installation and removal is not possible
Solution Approach 1:
The patent replaces traditional threaded fastening mechanisms with a bayonet-style quick-release connection. This mechanical substitution allows the stabilizer rod to be securely attached to the strut through a simple rotational locking action that can be performed without tools, while maintaining reliable attachment security during use.
Solution Approach 2:
The quick-release connection mechanism enables the user to install and remove the stabilizer rod independently without requiring additional tools or assistance. The self-contained design of the bayonet connection allows the entire attachment and detachment process to be performed by the user through simple manual operations.

AI summary
A stabilizer pole unit for a sunshade (18) in the form of an awning or a parasol has a pole (40) which is equipped on one side with a bottom end (20) and on the other side with a strut end (24). In order to stabilize the strut (14) of, for example, a parasol, the pole (40) is attached to the strut (14) at its upper end, with an additional angle adjustment device provided in this area.
