Drinking Straw Lip Stabilizer Design to Reduce Puckering and Creasing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Regular use of drinking straws can lead to permanent puckering and creases in the lips due to suction-induced lip contraction, which existing straw designs fail to mitigate effectively.
Innovation Solution
A drinking apparatus with a tubular body featuring a lip stabilizer section and a port located in the upper portion, configured to be horizontal and parallel to the lips, allowing liquid flow without penetrating the lips, thereby minimizing puckering and creasing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional straw is used for drinking, then liquid flow is enabled, but lip puckering and creases occur due to suction-induced lip contraction
Solution Approach 1:
The straw is divided into distinct functional sections: a lip stabilizer section with a flat outer surface that contacts the lips, and a tubular body section that enables liquid flow. This segmentation allows the flat section to distribute suction forces and prevent lip puckering while the tubular section maintains drinking functionality.
Solution Approach 2:
The lip stabilizer section has a different surface geometry (flat outer surface) compared to the tubular body section. This local quality change at the lip-contact region distributes the suction force across a broader area, preventing the concentrated force that causes lip puckering and creases.
2Stability of the object's composition
If the lip stabilizer section is added to prevent puckering, then lip stability is improved, but device complexity increases
Solution Approach 1:
The lip stabilizer section is integrated with the tubular body section to form a single unified apparatus. The flat outer surface section and the tubular body are joined together, combining the lip-stabilizing function with the liquid-flow function in one piece, thereby avoiding the need for separate components.
Solution Approach 2:
The lip stabilizer section serves multiple functions: it provides a flat surface for lip contact to prevent puckering, acts as a connector between the user's lips and the tubular body, and maintains structural integrity of the apparatus. This multi-functionality reduces the need for additional separate components.
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 apparatus reduces lip puckering and creasing over time, providing a stabilizing effect while enabling efficient liquid flow, and is attachable to conventional straws for enhanced user comfort.
Implementation Method 1
The user induces suction into one open end of the straw and in doing so, creates a puckering of the lips

AI summary
An apparatus for drinking featuring a tubular body with an open bottom end and a closed top end, the tubular body formed to provide a lip stabilizer section at or near horizontal and generally parallel to the lips of a user when in use. The apparatus for drinking further comprising a port in the wall of the tubular body located in the lip stabilizer section. When in use, the apparatus for drinking comes in contact with the lips of a user and the user induces suction to the tubular body through the port located in the lip stabilizer section. The suction induces the flow of liquids through the tubular body and through the port and into the mouth of a user. The lip stabilizer section provides a stabilizing effect to the lips of the user minimizing creases or folds in the lips of the user when in use.
