Compact Umbrella Hollow-Cylindrical Shell Handle Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible umbrellas lack a functional design that combines the umbrella shell and handle into a single, compact unit, offering limited functionality and durability, especially under adverse weather conditions.
Innovation Solution
A compact umbrella design featuring a hollow-cylindrical body that serves as both the umbrella shell and handle, with a connector allowing rotation from a closed position to an open handle position, utilizing various mechanical detachable connections for strength and ease of use, such as conical clamping, screw connections, and cam-rotation locks, to accommodate the main frame and provide ventilation and pressure equalization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the umbrella is designed with a separate shell and handle, then the structural complexity is higher, but the compactness and functionality are reduced
Solution Approach 1:
The patent merges the shell and handle into a single integrated hollow-cylindrical body. The connector serves dual purposes: as a support for the shell and as a handle when the umbrella is closed. This eliminates the need for separate components while maintaining all necessary functions, directly resolving the contradiction between functionality and structural complexity.
Solution Approach 2:
The hollow-cylindrical body is designed to perform multiple functions: it serves as the umbrella shell when open, as a protective case when closed, and as a carrying handle. This multi-functionality approach allows a single component to replace what would traditionally require multiple separate parts, enhancing versatility without increasing structural complexity.
2Reliability
If the connector is designed for strong connection, then the durability is improved, but the ease of operation is reduced
Solution Approach 1:
The connector is designed with dynamic characteristics, allowing it to be firmly connected during use for durability, but easily detachable when needed for operation. The connection mechanism provides stable support when the umbrella is open while enabling simple removal and reattachment, resolving the contradiction between strong connection and ease of operation.
3Volume of moving object
If the hollow-cylindrical body fully accommodates the folded umbrella, then the compactness is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The folded umbrella components are nested within the hollow-cylindrical body, with the main frame, canopy, and other elements arranged concentrically to maximize space utilization. This nesting arrangement achieves full accommodation in a compact form while maintaining reasonable manufacturing precision requirements through systematic component arrangement.

AI summary
A compact umbrella has a hollow-cylindrical body forming a shell, wherein the shell is made of a solid material and is configured to accommodate the umbrella in a transport state of the umbrella, when the umbrella is closed and folded, as a protective umbrella shell and is further configured to operate in an operating position of the umbrella, when opened, as a handle shell or carrying handle.
