Foldable Cup Sleeve With Hanging Ears for Space-Efficient Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper filter cups with V-shaped structures are inconvenient for carrying and cause over-compression of coffee granules, while screen-based filter cups require a separate holder and are not space-efficient for storage and portability.
Innovation Solution
A cup sleeve structure with hanging ears that supports screen-based filter cups, allowing for easy preparation of beverages, is designed to be space-efficient, portable, and user-friendly, featuring a foldable annular wall and removable hanging ears for secure attachment to a receiving cup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screen-based filter cup is used to avoid over-compression of coffee granules, then coffee brewing quality is improved, but the filter cup requires a separate holder and becomes less portable
Solution Approach 1:
The patent combines the cup sleeve and holder into a single integrated structure. The holder is formed as an extension of the cup sleeve body, eliminating the need for separate holder components. This merging allows the screen-based filter cup to be supported during brewing while maintaining portability, as the integrated structure can be folded into a compact form for carrying.
Solution Approach 2:
The cup sleeve is designed to perform multiple functions: it provides insulation for the cup, supports the screen-based filter cup during brewing through the integrated holder structure, and can be folded into a compact form for portable storage. This multi-functionality resolves the contradiction by making the system both effective for brewing and convenient for carrying.
2Ease of operation
If a cup sleeve structure is designed to be foldable for compact storage, then portability is improved, but the structural complexity increases
Solution Approach 1:
The cup sleeve is divided into multiple connected sections or panels that can be folded relative to each other. These segmented portions are joined through folding lines or creases, allowing the structure to collapse into a compact form while maintaining structural integrity when assembled. This segmentation enables portability without requiring complex mechanical mechanisms.

AI summary
This invention relates to a cup sleeve structure with hanging ears, which comprises a cup sleeve which has an annular wall body having a top opening and bottom opening on the two sides of the annular wall body, and at least two hanging ears, which can be bent and combined to the outer surface of the annular wall. By the implementation of the present invention, the cup sleeve structure having hanging ears can completely take up the least space while being stored, and can also be conveniently carried, and can support the filter cup body in use.
