Integrated leakproof cup cover for direct drinking and drinking with straw and cup having same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cup covers lack a single, leakproof structure that allows both direct drinking and drinking with a straw, and they are inconvenient to store a separate straw after use.
Innovation Solution
An integrated leakproof cup cover with a cup cover body and slider body, featuring a central through hole, drinking port, and a sliding push piece that rotates to open and seal the drinking port, allowing direct drinking and straw use, with a clamping part for secure attachment to the cup and a dust cap for straw storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded connection mode is used for the cup cover, then the sealing effect is improved, but the operation complexity increases and convenience decreases
Solution Approach 1:
The cup cover transitions from a static threaded connection to a dynamic snap-fit connection that can be quickly engaged and disengaged. The elastic component enables the cover to be quickly attached and detached without threading, maintaining sealing while improving operational convenience.
Solution Approach 2:
The threading mechanism is extracted and replaced with a snap-fit connection system consisting of a clamping ring and elastic component. This extraction eliminates the complex unscrewing operation while preserving the sealing function through the elastic seal.
2Adaptability or versatility
If a separate straw is used for drinking, then the drinking function is improved, but the device complexity and storage requirements increase
Solution Approach 1:
The straw function is merged with the cup cover by integrating a straw storage cavity directly into the cover structure. The dust cap serves dual purposes as both a protective cover and a straw holder, eliminating the need for separate straw storage and reducing overall device complexity.
Solution Approach 2:
The dust cap is designed with multi-functionality: it protects the drinking port, stores the straw, and can be removed to allow direct drinking or straw insertion. This universal component performs multiple functions that would otherwise require separate parts.
3Adaptability or versatility
If the cup cover is designed with multiple functions, then the versatility is improved, but the structure complexity increases
Solution Approach 1:
Multiple drinking functions (direct drinking and straw drinking) are merged into a single cup cover design. The cover integrates a drinking port, straw storage cavity, and dust cap that works with both drinking methods, providing versatility without requiring separate components for each function.
Solution Approach 2:
The cup cover is designed as a universal component that supports multiple drinking methods. The dust cap and straw storage cavity enable the cover to function whether using a straw or drinking directly, making the structure adaptable to different user preferences without adding complexity.
