Umbrella Handle and Top Integrated Waterproof Storage Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional umbrellas with built-in storage solutions are cumbersome and prone to water leakage when storing a wet umbrella, as they require separate plastic bags or complicated assembly processes.
Innovation Solution
An umbrella with a built-in waterproof case that transforms the handle and top into a storage compartment, featuring a fixed handle part, rotating handle part, sliding handle part, and an umbrella top with hemispherical protrusions and a waterproof ring, allowing the umbrella shaft to be inserted and fixed, enabling easy opening and closing, and featuring through drain holes for water removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate plastic bag is used to store a wet umbrella, then water leakage is prevented, but the device complexity increases and portability is reduced
Solution Approach 1:
The patent combines the umbrella handle and umbrella top to form an integrated storage case that houses the folded umbrella body. This merging eliminates the need for separate plastic bags or storage bags, preventing water leakage while maintaining simplicity and portability.
Solution Approach 2:
The umbrella handle and top serve dual functions: as structural components of the umbrella and as a waterproof storage case for the folded umbrella body. This multi-functionality eliminates the need for additional storage accessories.
2Ease of operation
If a storage bag is used to accommodate the umbrella, then the umbrella can be stored, but the process of tying or releasing it is cumbersome
Solution Approach 1:
The storage case is integrated into the umbrella structure itself, with the handle and top forming enclosing walls. The folded umbrella body is directly inserted into this space, eliminating the need for separate storage bags and their associated tying operations.
Solution Approach 2:
The patent employs a sliding mechanism where the sliding handle part moves along the umbrella shaft to open or close the storage case. This dynamic structure allows quick access to the stored umbrella without complex tying or untying processes.
3Ease of operation
If the storage bag is tied to the ring of the umbrella handle, then the umbrella can be carried, but the risk of loss increases
Solution Approach 1:
The storage case is structurally integrated into the umbrella handle and top, forming a unified assembly. This integration eliminates the risk of the storage bag being lost, as it becomes an inherent part of the umbrella structure rather than a separate accessory.
4Adaptability or versatility
If conventional built-in storage structures are used, then the umbrella can be stored in the handle, but the process is complicated
Solution Approach 1:
The patent divides the handle into distinct functional parts: a fixed handle part, a rotating handle part with bearing balls, and a sliding handle part. This segmentation allows each component to perform its specific function while maintaining overall simplicity in the assembly and disassembly process.
Solution Approach 2:
The rotating handle part can rotate relative to the fixed handle part, and the sliding handle part can move along the umbrella shaft. These dynamic elements enable easy opening and closing of the storage case without complicated assembly procedures.

AI summary
The present invention relates generally to an umbrella having a built-in waterproof case, in which a folded umbrella main body is accommodated in an umbrella handle, and more particularly to an umbrella having a built-in waterproof case, which, in order to carry or store a wet folding umbrella used, allows an umbrella handle and an umbrella top to be transformed into an umbrella storage case without using a separate plastic bag and then allows the umbrella to be easily opened or re-stored while allowing a folded umbrella body to be accommodated in the umbrella handle.
