Portable Cup Holder String Layout for Upright Carrying Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable cup holders are structurally complex due to the need for a top sleeve to position the handle string, leading to potential swinging during carrying and an inability to maintain the cup upright.
Innovation Solution
A portable cup holder design featuring curved cup-embracing walls with spaced-apart holes for loop-shaped string parts that extend through these holes, allowing the strings to shift and maintain the cup upright, forming a continuously extending endless string for stable handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a top sleeve is used to position the handle string, then the cup holder can maintain its structure, but the structure becomes complex and the cup holder may swing during carrying
Solution Approach 1:
The patent removes the top sleeve component from the conventional design and replaces it with a simplified structure where the handle string directly extends through the cup holder body. The string passes through openings in the cup-embracing walls without requiring a separate positioning sleeve, thereby eliminating the complex assembly while maintaining structural integrity.
Solution Approach 2:
The cup holder is divided into distinct functional components: the cup-embracing walls with openings, the handle string unit, and the connecting mechanism. This segmentation allows each component to perform its specific function independently, simplifying the overall structure while maintaining stability.
2Stability of the object's composition
If the handle string is connected to the cup holder, then the cup holder maintains its form, but the cup holder swings during carrying and cannot maintain the cup upright
Solution Approach 1:
The handle string is designed to be movable relative to the cup holder body, allowing it to dynamically adjust its position. The string can shift and reposition itself in response to external forces during carrying, preventing swinging motion while maintaining the cup's upright position through adaptive positioning rather than rigid connection.
Solution Approach 2:
The handle string acts as an intermediary element between the user's hand and the cup holder. By allowing the string to move and shift independently, it absorbs and dampens swinging forces, preventing them from being transmitted to the cup holder and maintaining stability during carrying.

AI summary
A portable cup holder includes: a cup-holding unit including a first cup-embracing wall that is formed with two first wall holes and a second cup-embracing wall that is formed with two second wall holes aligned with the first wall holes; and a handle string unit including first and second string parts, each of which extends from outside of the cup-holding space through one of the first wall holes into the cup-holding space and then through one of the second wall holes to the outside of the cup-holding space and then extends therefrom through the other of the second wall holes into the cup-holding space and then through the other of the first wall holes to the outside of the cup-holding space. Each of the first and second string parts is shiftable along a transverse direction.
