Leakproof Straw Lid with Movable Plug for Drinking Vessels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straw lids for drinking tumblers are not leakproof, leading to spills when the vessel is knocked over or turned upside down.
Innovation Solution
A leakproof lid design for drinking vessels, featuring a bottom lid portion with an externally threaded connection, a straw connector portion with a plug to seal the straw in the closed position, and a top lid portion that creates a fluid-tight seal with the straw, allowing for easy transition between open and closed positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional straw lid is used, then the lid allows easy fluid flow and operation, but the lid is not leakproof and spills when the vessel is knocked over or turned upside down
Solution Approach 1:
The lid incorporates a movable plug that can transition between different positions: in the closed position, the plug seals the straw opening to prevent leaks; in the open position, the plug moves to allow fluid flow. This dynamic element enables the lid to adapt its sealing behavior based on operational state, resolving the contradiction between leakproofness and ease of operation
Solution Approach 2:
The lid design changes the sealing parameter dynamically - when closed, the plug engages with the straw opening to create a fluid-tight seal; when opened, the seal is broken to permit fluid flow. This parameter change between sealed and open states allows the lid to achieve both leakproof performance and operational ease
2Reliability
If a plug is added to seal the straw in the closed position, then leakproof performance is improved, but device complexity increases
Solution Approach 1:
The plug is integrated as part of the bottom lid portion rather than being a separate removable component. This merging of the sealing element with the lid structure itself adds leakproof functionality without significantly increasing device complexity, as the plug moves within the existing lid architecture rather than requiring additional separate parts

AI summary
A lid connectable to a drinking vessel. The lid has a bottom lid portion, a top lid portion, a first straw and a second straw. The bottom lid portion has a top, a bottom and a sidewall defining an interior space having a straw connector portion. The top lid portion is connected to the bottom lid portion. The top lid portion has a top surface, a bottom surface and an opening having a passageway extending therebetween. The first straw has a first end, a second end, a passageway therebetween and a connector that removably connects the first straw to the straw connector portion of the bottom lid portion. The second straw has a first end, a second end, a passageway therebetween and a connector that removably connects the second straw to the opening of the top lid portion.
