Closed Hollow Pole Structure for Stronger Planting Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing planting devices lack structural strength and durability, particularly in the design of poles with open hollow column structures that are prone to bending and deformation.
Innovation Solution
The planting device incorporates closed hollow cylindrical poles with an annular cross-section, featuring an outer and inner plate portion that enhances rigidity, and a support assembly with adjustable height and ventilation channels for improved stability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If open hollow column structure with C-shaped or U-shaped cross section is used for poles, then ease of manufacture is improved, but structural strength and durability deteriorate
Solution Approach 1:
The patent changes the pole cross-section from open C-shaped or U-shaped to closed circular or annular shape. This curvature transformation provides superior structural strength and rigidity while maintaining ease of manufacture through standard pipe or tube fabrication processes.
2Ease of operation
If open hollow column structure with through groove is used for poles, then ease of assembly is improved, but structural strength deteriorates
Solution Approach 1:
The patent introduces reinforcing ribs or stiffeners at specific locations on the pole surface where connections are needed. This allows snap-on structures to be attached effectively without compromising the overall structural integrity of the closed hollow section, as the reinforcement is applied locally rather than opening the entire structure.
3Strength
If closed hollow cylindrical poles with annular cross-section are used, then structural strength is improved, but device complexity increases
Solution Approach 1:
The closed hollow cylindrical shape with annular cross-section provides inherent structural strength and rigidity. While the shape is more complex than open sections, it can be manufactured as a single integrated component using standard pipe or tube extrusion processes, which actually simplifies the overall device assembly by reducing the number of parts needed.

AI summary
A planting device includes at least one bottom board, baffles, connecting plates, and poles. The baffles are distributed on a circumference of the bottom board. The connecting plate connects adjacent two baffles. The poles are correspondingly connected to the connecting plates. The pole includes an outer plate portion and an inner plate portion, the outer plate portion is connected to the corresponding connecting plate, the inner plate portion supports the bottom board; a hollow space is formed between the outer plate portion and the inner plate portion, two sides of the outer plate portion are respectively connected to two sides of the inner plate portion to enclose the hollow space.
