Segmented Cantilever Umbrella Arms for Compact Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cantilever umbrellas with elongated curved poles require large transportation cases, increasing costs, and fixed-angle canopies cannot be adjusted to suit varying conditions.
Innovation Solution
A cantilever umbrella design featuring a locking block, first and second cantilever arms connected by screws, a locking sliding sleeve, and pulleys with rolling balls, allowing the arms to be disassembled for reduced packaging and the canopy angle to be adjusted by sliding the arms within the locking block and sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an elongated curved pole is adopted as a cantilever arm pole, then the shading function is achieved, but the transportation case size increases and costs increase
Solution Approach 1:
The cantilever arm is divided into multiple segments (first cantilever arm and second cantilever arm) that can be disassembled and stored within the base structure. This segmentation allows the shading arm to be compact for transportation while maintaining its full extended functionality for shading, directly resolving the contradiction between shading capability and transportation volume.
2Device complexity
If a fixed-angle canopy is used, then the structure is simple, but the canopy angle cannot be adjusted according to actual conditions
Solution Approach 1:
The canopy angle is made dynamically adjustable through a telescopic cantilever arm mechanism with multiple position settings. The arm can be extended or retracted to different lengths and angles, allowing the canopy to adapt to various sunlight directions and shading requirements while maintaining a relatively simple overall structure through modular design.
3Volume of moving object
If the cantilever arm is made telescopic and disassemblable, then transportation costs are reduced, but the structure becomes more complex
Solution Approach 1:
The telescopic cantilever arm mechanism is integrated into the base structure, merging the arm support function with the base. The locking blocks, sliding sleeves, and connection mechanisms are combined into a unified system where multiple components work together within the base housing, reducing overall structural complexity while enabling disassembly and compact storage for cost-effective transportation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces transportation costs by allowing the arms to be disassembled and facilitates convenient adjustment of the canopy angle, enhancing usability and reducing the size of the packaging case.
Implementation Method 1
A plurality of first pulleys are disposed in the locking block; a second pulley is disposed in the locking sliding sleeve; a rolling ball is disposed in each of the first pulley and the second pulley

AI summary
Provided is a cantilever umbrella. The technical solution of this application is that the cantilever umbrella includes a canopy, a base, and an upright pole. The upright pole is disposed on the base. A locking block is fixedly disposed on the upright pole. A fixed rod, a first cantilever arm, and a second cantilever arm are disposed on the locking block. A connector on the first cantilever arm is connected to a protruding portion on the second cantilever arm through a second screw, thereby facilitating dismounting of the first cantilever arm and the second cantilever arm. After the first cantilever arm and the second cantilever arm are dismounted, a size of a transportation case can be reduced when the cantilever umbrella is packaged for transportation, and therefore, costs are reduced. When the first cantilever arm and the second cantilever arm slide in the locking block and a locking sliding sleeve, an angle of the canopy is adjusted with sliding of the first cantilever arm and the second cantilever arm. In this way, the angle of the canopy is conveniently adjusted by sliding the first cantilever arm and the second cantilever arm in the locking block and the locking sliding sleeve. This application has effects of saving transportation cost, and conveniently adjusting the angle of the canopy.
