Detachable Straw Assembly with Elastic Base for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking water containers with integrated straws are inconvenient to use, difficult to clean, and challenging to replace the straw, as they require unscrewing the cup cover for filling and cleaning.
Innovation Solution
A combined straw system comprising a rigid tube, a hose, and an elastic installing base that is detachably sleeved in the drinking water outlet of a cover body, allowing for easy installation, disassembly, and cleaning, with a design that includes a snap-fitting convex ring, a groove for forming a vacuum, and a spring for automatic ejection of the rigid tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the straw is integrated with the cup cover as a whole, then the structure is simple and stable, but it is inconvenient to use, difficult to clean, and hard to replace the straw
Solution Approach 1:
The straw system is divided into separate components: the cup cover, the straw assembly (rigid tube, hose, and elastic installing base), and the top cover. The elastic installing base can be detachably sleeved in the drinking water outlet of the cover body, allowing the straw to be independently installed, removed, and cleaned without disassembling the entire cup cover structure.
Solution Approach 2:
The elastic installing base incorporates a spring mechanism that provides dynamic functionality. When the top cover is buckled with the cover body, the spring compresses to secure the rigid tube. When the top cover is removed, the spring elastically resets to push the rigid tube out, enabling automatic ejection and simplifying straw replacement.
2Ease of operation
If the cup cover is unscrewed for filling water, then water can be filled, but it is very inconvenient to use
Solution Approach 1:
The top cover is designed with articulation to the cover body, allowing it to be easily opened and closed without unscrewing. The buckling mechanism provides secure closure while enabling quick opening for filling water, significantly reducing the time and effort required compared to traditional screw-on covers.
3Ease of operation
If the straw is cleaned together with the cup cover, then both are cleaned, but it is difficult to clean the straw
Solution Approach 1:
The straw assembly is designed as a separable component that can be easily detached from the cup cover. The elastic installing base allows the straw to be removed by simply unbuckling the top cover, enabling the straw to be cleaned separately with appropriate tools and solutions, ensuring thorough cleaning that would be difficult if cleaned together with the cover.
4Reliability
If the groove forms a vacuum, then the connection between rigid tube and hose is tighter, but it requires pressing the hose
Solution Approach 1:
The groove on the rigid tube is designed to form a vacuum when the hose is pressed onto it. This vacuum effect creates a tight seal and secure connection between the hose and rigid tube. The pressing action during installation temporarily overcomes the vacuum force, but once installed, the vacuum maintains reliable connection without requiring additional fastening mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables easy installation and disassembly of the straw, facilitates cleaning, and allows for the replacement of the hose, while maintaining a secure connection through vacuum formation, all without the need for manual handling that could lead to contamination.
Implementation Method 1
the elastic installing base is elastically reset, thereby pushing the rigid tube out of the drinking water outlet and simultaneously opening the top cover
Implementation Method 2
the users may allow the groove to form a vacuum by pressing the hose, so that a connection between the rigid tube and the hose is tighter
Data Source
AI summary
The present disclosure provides a straw and a straw bottle containing a combined straw. The straw includes a rigid tube, a hose sleeved to a bottom of the rigid tube, and an elastic installing base sleeved on an outside of the rigid tube. The elastic installing base is detachably sleeved in a drinking water outlet of a cover body. When a top cover is buckled with the cover body, the top cover presses the rigid tube, so that the hose is in a compression and bending state, and the straw is placed in the drinking water outlet. Thus, a user may disassemble and assemble the straw, which is convenient for the cleaning of the straw.
