Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable cup holders made of paper material are inefficient due to excessive material usage, instability under the weight of contents, and complex manufacturing processes, leading to high costs and logistical challenges.
Innovation Solution
A portable cup holder with a simplified structure that minimizes material usage, features a folding design for easy assembly, and incorporates a fixing mechanism with corrugated surfaces and slip-preventing features to securely hold cups, reducing the risk of spilling and dislocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional paper material cup holders are used, then cups can be held, but the cup holder requires lots of paper material and the cup tends to be detached or escape due to weight of contents
Solution Approach 1:
The cup holder is divided into multiple functional portions (bottom portion, fixing portion, rising portion, top portion, handle portion) that are connected through folding lines, allowing each segment to perform its specific function while using minimal material
Solution Approach 2:
The cup holder utilizes corrugated portions with slip-preventing surfaces combining structural rigidity and friction-based grip to hold cups securely with minimal material
2Reliability
If conventional paper material cup holders are used, then cups can be held, but the folding assembly process is inconvenient and time-consuming and manufacturing processes are complicated
Solution Approach 1:
The cup holder is designed with pre-formed folding lines and cutting portions that guide the assembly process, allowing rapid folding and assembly without complex manufacturing steps
Solution Approach 2:
The cup holder transitions from a flat planar figure to a three-dimensional structure through dynamic folding of connected portions, enabling easy assembly and disassembly while maintaining structural stability
3Reliability
If conventional paper material cup holders are used, then cups can be held, but the volume of the cup holder is big making it difficult to load, transport, and store
Solution Approach 1:
The cup holder portions are designed to nest within each other when folded, with the top portion containing the handle portion and all portions collapsing into a compact form factor for efficient storage and transport
Solution Approach 2:
The cup holder dynamically transforms between an expanded functional state for holding cups and a compact folded state for storage, minimizing volume while maintaining structural integrity during use
4Reliability
If conventional paper material cup holders are used, then cups can be held, but the cup could be shaken in the inner space causing contents to spill
Solution Approach 1:
The cup holder incorporates localized slip-preventing surfaces and corrugated portions at specific contact points with the cup, providing enhanced grip and stability without requiring complex structures throughout the entire holder
Solution Approach 2:
The corrugated portions feature curved surfaces that conform to the cup shape, increasing friction and preventing the cup from shaking or slipping within the holder

AI summary
The invention provides a portable cup holder for carrying a cup with, for example, take-out coffee. The portable cup holder is made with a minimum amount of material that may be folded rapidly and easily, and comprises a bottom portion 1 forming a bottom surface through which a cup opening 3 is formed, a fixing portion 4 connected to top and bottom ends of the bottom portion 1 and folded vertically, a rising portion 7 folded and disposed vertically at right and left ends of the bottom portion 1, a top portion 2 connected to the rising portion 7 forming a top surface and including the cup opening 3a, and a handle portion 10 folded vertically upwards at the top portion 2 that forms a handle.
