Standing Parasol Ring Layout to Prevent Dirt and Wind Shake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing standing parasols suffer from exposure of the telescopic tube in the open position, leading to dirt accumulation and potential shaking in windy conditions, particularly in designs without a telescopic tube.
Innovation Solution
The parasol design features a configuration where the central and upper articulation rings are in a substantially adjacent state, with specific diameters and strut arrangements to maintain symmetry and prevent exposure, and includes a tensioning device for fixing the open position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the parasol is designed without a telescopic tube or with the upper articulation ring exposed in the open position, then the manual operation is simplified and the structure is simplified, but the telescopic tube becomes exposed and accumulates dirt and wind-borne rainwater
Solution Approach 1:
The upper articulation ring is nested within the central articulation ring when the parasol is in the open position. The upper articulation circle is received by the central articulation circle, creating a nested configuration that prevents exposure of the telescopic tube and eliminates the space where dirt and rainwater could accumulate.
2Device complexity
If the parasol is designed without a telescopic tube or with exposed upper articulation ring, then the structure is simpler, but lateral shaking occurs in windy conditions
Solution Approach 1:
The nested configuration of the upper articulation ring within the central articulation ring provides structural stability. The articulation points are arranged such that the upper articulation circle is received by the central articulation circle, creating a stable nested structure that resists lateral shaking in windy conditions.
Solution Approach 2:
The central articulation ring and upper articulation ring are merged in space when the parasol is open, with the upper articulation circle being received by the central articulation circle. This merging of the two rings creates a more stable unified structure that prevents lateral shaking.
3Object-affected harmful factors
If the central and upper articulation rings are positioned adjacently in the open position, then dirt accumulation and shaking are prevented, but the mechanism becomes more complex
Solution Approach 1:
The upper articulation ring is nested within the central articulation ring in the open position, with the upper articulation circle received by the central articulation circle. This nested arrangement prevents dirt accumulation while using the existing articulation mechanism without adding significant complexity.
Solution Approach 2:
The articulation mechanism allows dynamic movement between the closed and open positions. In the open position, the upper articulation ring moves to nest within the central articulation ring, while in the closed position, the rings are separated. This dynamic behavior achieves the desired protection without requiring a permanently complex structure.
