Umbrella Case With Elastic Sheath And Adjustable Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional umbrella cases often require manual handling or additional carrying means, and lack versatility in accommodating umbrellas of different fixed lengths, with inadequate protection against water runoff.
Innovation Solution
A waterproof umbrella case featuring an elastic sheath and spike-receiving portion, along with a fastening strap and adjustable carrying strap, designed to securely hold long-stick umbrellas of varying sizes, allowing for easy handling and water drainage, with optional waterproof housing for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional umbrella case is used, then the umbrella is protected from water runoff, but the user must use at least one hand to carry it or supply additional carrying means
Solution Approach 1:
The patent combines the umbrella case with a belt clip attachment mechanism, merging the protective case function with the carrying function into a single integrated device that can be secured to the user's belt, thereby achieving hands-free carrying while maintaining water runoff protection
Solution Approach 2:
The belt clip acts as an intermediary element that connects the umbrella case to the user's clothing or belt, providing a secure attachment mechanism that enables hands-free carrying without requiring the user to hold the case
2Adaptability or versatility
If a conventional umbrella case is used, then it is designed specifically for one umbrella, but it cannot accommodate umbrellas of different fixed lengths
Solution Approach 1:
The patent employs an adjustable internal support structure that can be dynamically repositioned to accommodate umbrellas of different lengths. The support features movable elements or adjustable components that adapt to various umbrella dimensions while maintaining a relatively simple overall case design
Solution Approach 2:
The case design incorporates segmented or modular components, particularly in the internal support structure, allowing adjustment for different umbrella lengths without requiring complete redesign of the entire case

AI summary
An umbrella case configured to hold an umbrella having a rigid shaft with a handle at one end and a spike at the other end, the umbrella case comprising an umbrella holding assembly comprising a generally tubular sheath 106 having an open end and a spike-receiving portion 107 defining a spike-receiving aperture at the other end, and a fastening strap 100 having a first end coupled to an outer surface of the umbrella case, close to the open end of the sheath 106, and having a second, free end configured to be selectively moved to a fastening position in which it is connected to the umbrella case at a generally diametrically opposite location to the first end, the sheath, the spike-receiving portion and the fastening strap when in the fastening position, together, defining the effective length of the umbrella holding assembly, wherein at least one of the sheath, the spike-receiving portion and the fastening strap is selectively longitudinally extendible upon application of a force, in use, thereby to increase the effective length of the umbrella holding assembly to accommodate the length of an umbrella held therein.
