Container Lid with Auto-Extending Straw and Dual Drinking Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cups with two drinking openings on the market require users to manually straighten the straw after it has been pressed, as the straw does not automatically pop up when switching from direct drinking to straw usage, leading to inconvenient and potentially unsanitary drinking experiences.
Innovation Solution
A container lid with a movable closure member and a straw locking mechanism that allows the straw to automatically pop up when the user selects the straw opening, featuring a button-operated system with inclined surfaces and elastic members to facilitate easy operation and prevent water leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the straw is pressed by the upper lid for storage, then the lid structure is simple and compact, but the straw does not automatically pop up when needed and requires manual straightening
Solution Approach 1:
The straw is designed to be movable rather than fixed, allowing it to dynamically transition between a compressed storage state (when the closure member is closed) and an extended usage state (when the closure member is opened). This dynamic design enables the straw to automatically pop up when needed, resolving the contradiction between simple structure and ease of operation.
2Reliability
If two separate upper lids are used to cover the direct drinking opening and straw opening, then each opening is independently protected, but the user needs to open different lids to select drinking ways increasing operation complexity
Solution Approach 1:
The patent combines the protection of both the direct drinking opening and straw opening into a single closure member. This unified closure member can simultaneously cover both openings when in the closed position, allowing users to select drinking methods by opening the single closure member rather than manipulating multiple separate lids, thus reducing operational complexity while maintaining protection reliability.
3Volume of moving object
If the straw is stored by being pressed by the upper lid, then the storage space is efficient, but the straw may not immediately pop up after long time compression requiring manual intervention
Solution Approach 1:
The closure member is designed to perform a preliminary expanding action on the straw when opened. As the closure member moves from the closed to open position, it automatically applies an expanding force to the compressed straw, preliminarily restoring it to its extended state before the user needs to use it. This preliminary action ensures the straw is ready for immediate use without requiring manual straightening.
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
Enables convenient and sanitary drinking by allowing the straw to automatically extend when needed, preventing manual handling and ensuring the lid can be quickly opened and closed, reducing the risk of water spillage and maintaining cleanliness.
Implementation Method 1
a first elastic member arranged between the straw limiting member and the straw guide member; and the first elastic member promotes the straw to extend out of the straw opening
Implementation Method 2
a second elastic member for keeping the closure member in an open state arranged between the rotating shaft and the lid body
Implementation Method 3
a third elastic member arranged between the button and the lid body, and the third elastic member provides a force for the button to be in a locked state
