Portable Cup Holder With Rotating Placing Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable cup holders are limited to carrying a single drink cup, making them inconvenient for carrying multiple cups, and existing solutions like mesh or paper bags can cause cups to tilt and leak.
Innovation Solution
A portable cup holder with multiple rotating placing sheets, a connection shaft, and a carry strap that allows the sheets to be adjusted to accommodate one to four drink cups by rotating along the connection shaft, ensuring secure and upright carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional carry strap with a single circular accommodation space is used, then a single drink cup can be carried, but carrying multiple drink cups becomes inconvenient
Solution Approach 1:
The carry strap is divided into multiple independent placing sheets (first, second, third, fourth placing sheets) that can be independently rotated and positioned. Each placing sheet has its own receiving orifice for holding a drink cup, allowing the user to carry multiple cups simultaneously while maintaining simple individual structures for each placing sheet
Solution Approach 2:
The placing sheets are designed to be rotatable along the connection shaft, transforming the static single-cup holder into a dynamic multi-cup holder. The user can rotate the placing sheets to different positions (first, second, third, fourth positions) to accommodate multiple cups in various configurations, enhancing adaptability without permanently complicating the structure
2Ease of operation
If mesh bags or paper bags are used to carry multiple drink cups, then carrying convenience is improved, but the cups may tilt and leak liquids
Solution Approach 1:
Each placing sheet provides a separate, dedicated receiving orifice for individual cup placement. This segmentation ensures that each cup is independently secured in its own compartment, preventing cups from tilting or contacting each other, thereby eliminating leakage risks while maintaining carrying convenience
Solution Approach 2:
Each placing sheet has a specifically designed receiving orifice with dimensions matched to the cup's outer wall, creating a localized secure fit for each cup. This local customization ensures that each cup is held firmly in its specific position, preventing tilting and leakage while maintaining overall carrying ease

AI summary
A portable cup holder contains: multiple placing sheets, a connection shaft, and a first carry strap. A respective placing sheet includes a receiving orifice defined on a first side thereof, and the respective placing sheet includes a rotating orifice formed on a second side thereof. The connection shaft is inserted through the rotating orifice of the respective placing sheet to rotate the respective placing sheet along the connection shaft, and the connection shaft includes a hollow orifice and a partition post horizontally extending in the hollow orifice. The first carry strap is formed in a ring shape and includes an accommodation space defined inside the first carry strap, the partition post of the connection shaft is received in the accommodation space of the first carry strap so that the first carry strap is connected with the connection shaft and is pulled to the partition post upward or downward.
