Floating Sleeve Straw Assembly for Any-Angle Drinking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straw cups for infants and children fail to enable effective any-angle drinking without sucking air, as weighted straws often bend and collapse, and lack visual interest, while floating straws are not designed for this purpose.
Innovation Solution
A modified straw with first and second holes on its lateral surface and a movable floating sleeve element that switches positions to allow liquid access while preventing air intake, ensuring drinking is possible at any angle without sucking air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a weighted straw is used to enable any angle drinking, then the straw can stay in position at various angles, but the straw bends and collapses making it impossible for the child to suck liquid
Solution Approach 1:
The patent uses a floating element that provides buoyant force to counteract the weight of the straw, preventing it from bending or collapsing. The floating element acts as a counterweight that maintains the straw's structural integrity while enabling it to function at various angles including upside-down positions.
Solution Approach 2:
The patent changes the density parameter of the straw assembly by incorporating a floating element with lower density than the surrounding liquid. This parameter change allows the straw to float and maintain its shape at various angles without bending or collapsing under its own weight.
2Adaptability or versatility
If a weighted straw is used for any angle drinking, then the straw can maintain position, but it has a technical appearance that does not add visual interest
Solution Approach 1:
The floating element is designed with vibrant colors or visual features that make the straw assembly aesthetically pleasing. This visual enhancement transforms the technical appearance into an attractive design that captures children's interest while maintaining the any-angle drinking functionality.
Solution Approach 2:
The floating element can be designed to resemble playful objects or characters, creating a visually interesting appearance that appeals to children. This copying approach allows the straw to have an engaging aesthetic without compromising its functional integrity.
3Reliability
If floating straws are designed to stay afloat or prevent exit, then they can remain in position, but they are not designed for any angle drinking and cannot prevent air suction
Solution Approach 1:
The straw is divided into functional segments: a floating element for stability, a straw body for liquid transport, and strategically placed holes for air management. This segmentation allows each part to perform its specific function, enabling any-angle drinking while preventing air suction through coordinated operation of the different segments.
Solution Approach 2:
The floating element acts as an intermediary that connects the straw to the liquid, maintaining contact and preventing air entry while allowing the straw to function at various angles. This intermediary component mediates between the need for stability and the need for any-angle drinking capability.
4Adaptability or versatility
If holes are arranged on the lateral surface of the straw, then liquid can access the straw at any angle, but air may enter the straw causing suction of air instead of liquid
Solution Approach 1:
The floating element automatically adjusts its position based on buoyancy to self-regulate air and liquid access. When the cup is tilted or inverted, the floating element moves to block air-containing holes while opening liquid-containing holes, providing automatic air prevention without external control mechanisms.
Solution Approach 2:
The straw assembly incorporates dynamic elements that move in response to changes in cup orientation. The floating element dynamically adjusts its position along the straw to maintain proper sealing and opening of holes, ensuring liquid access at any angle while preventing air intake through motion-driven adaptation.

AI summary
The present invention relates to a straw (1), a straw assembly (2) and a cup assembly (3). The straw (1) comprises first holes (13) in an upper half and second holes (14) in a lower half both arranged at the lateral surface of the straw (1). A sleeve element (20) can be arranged coaxially to and around the straw (1) to form a straw assembly (2). The sleeve element (20) is configured to close the first holes (13) in a first position and the second holes (14) in a second position. The straw assembly (2) can be arranged in a cup assembly (3). As the sleeve element (20) is also configured to float in a liquid the sleeve element (20) is moved through the force of buoyancy either to the first or the second position depending on the inclination of the cup assembly (3) with respect to the force of gravity. This provides a solution for any angle drinking.
