Compact Umbrella Roller Winding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional umbrellas struggle to achieve a compact accommodation volume while maintaining ease of use, as increased folding complexity makes them difficult to grip and carry.
Innovation Solution
A portable compact umbrella design featuring a cylindrical case with a wider diameter than height, a rotating roller, and a deformable umbrella ring that allows the umbrella fabric to be wound in a vortex shape, facilitated by magnetic coupling and fixing members, enabling easy unfolding and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the number of folding the umbrella frame is increased to reduce accommodation volume, then the accommodation volume decreases, but the umbrella frame structure becomes complex and difficult to grip
Solution Approach 1:
The patent implements nesting by placing the roller inside the case, and the umbrella fabric and ring wrapped around the roller inside the case. This nested arrangement allows the umbrella components to be compactly stored within the case while maintaining a simple overall structure that can be easily gripped by one hand.
Solution Approach 2:
The patent changes the accommodation volume reduction approach from multiple folding operations in one dimension to a compact cylindrical case design in three dimensions. The roller-wrapped fabric arrangement allows the umbrella to occupy minimal space within the cylindrical case while keeping the frame structure simple.
2Ease of operation
If the accommodation volume is reduced to enable easy carrying, then the umbrella becomes more portable, but the structure becomes overly complex
Solution Approach 1:
The case contains the roller, which in turn contains the wrapped umbrella fabric and ring. This nested configuration achieves compact portability while avoiding excessive structural complexity by using a straightforward hierarchical containment approach.
Solution Approach 2:
The patent divides the umbrella into distinct functional segments: the case for storage, the roller for winding, the ring for structural support, and the fabric for coverage. This segmentation allows each component to perform its function with simple geometry, avoiding the need for complex integrated structures.
3Volume of moving object
If the umbrella frame is folded multiple times to minimize size, then the accommodation volume is reduced, but the gripping difficulty increases
Solution Approach 1:
The nested case-roller-fabric arrangement minimizes accommodation volume to a compact cylindrical form that fits easily in one hand, eliminating the need for multiple folding operations that would create complex gripping difficulties.
Solution Approach 2:
Instead of folding the frame multiple times to reduce size, the patent inverts the approach by using a roller-wrapped fabric system within a compact case. This inversion achieves size reduction without creating gripping complexity.
