Rotating Cup Lid with Stopper Seals Drinking Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beverage lids fail to effectively protect the drinking hole from contaminants, lead to splashing and leakage, and do not indicate the beverage's temperature, posing health and safety hazards.
Innovation Solution
A lid design featuring a rotating cover with a stopper that can be removably attached, a splash guard, and a heat indicator to prevent contamination and leakage, while providing a secure drinking mechanism and temperature indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple uncovered hole is used for drinking, then the lid structure is simple and easy to manufacture, but the drinking hole is exposed to dust, germs, and other particles from the air
Solution Approach 1:
The lid is divided into multiple functional components: a base with drinking hole, a rotating cover that can open/close, and a stopper mechanism. This segmentation allows each part to perform its specific function while maintaining overall simplicity of manufacturing.
Solution Approach 2:
The stopper acts as an intermediary element that can be placed in the drinking hole to block contaminants, while the rotating cover provides an additional protective barrier. These intermediaries protect the drinking hole without requiring complex manufacturing.
2Device complexity
If the lid has a simple uncovered hole, then the structure remains simple, but beverage can splash out when the cup is jostled or bumped
Solution Approach 1:
The cover is designed to rotate rather than be fixed, allowing it to dynamically respond to movement and pressure changes. This dynamic mechanism prevents splashing while maintaining structural simplicity.
Solution Approach 2:
The stopper serves as an intermediary barrier in the drinking hole that prevents beverage from splashing out during movement, while the rotating cover provides an additional dynamic barrier.
3Ease of operation
If the drinking hole is left open, then the lid is simple to operate, but heat from the warm beverage escapes faster leading to a cold drink
Solution Approach 1:
The rotating cover provides a dynamic sealing mechanism that can be easily opened for drinking and closed for heat retention. This simple rotational motion effectively controls heat escape while maintaining ease of operation.
Solution Approach 2:
The cover can remain closed continuously when not drinking, providing continuous heat retention. The simple rotational mechanism allows quick opening when needed, maintaining both temperature and ease of operation.
4Object-affected harmful factors
If a cover is added to protect the drinking hole, then contamination is prevented, but the device complexity increases
Solution Approach 1:
The protective function is segmented into two simple components: the rotating cover that provides primary protection and the stopper that provides secondary protection. This segmentation achieves effective contamination prevention without excessive complexity.
Solution Approach 2:
The rotating cover serves multiple functions: it protects the drinking hole from contamination, prevents splashing, and retains heat. This multi-functionality reduces the need for additional components, maintaining simplicity while providing comprehensive protection.
5Reliability
If the lid components are securely connected to prevent leakage, then beverage leakage is prevented, but the ease of cleaning and maintenance decreases
Solution Approach 1:
The lid is segmented into removable components (base, cover, stopper) that can be easily separated for cleaning. The securing mechanism uses simple projections and recesses that allow easy assembly and disassembly, maintaining both leakage prevention and ease of maintenance.

AI summary
The current invention relates to a lid for a cup which protects the contents of the cup and the drinking hole from contaminants. In some embodiments the lid for a cup includes a base and a cover connected to the base which rotates around the base. In this way the cover protects the drinking hole when closed, but can rotate open to allow the user to access the drinking hole and the contents of the cup. In some embodiments the cover is further equipped with a stopper which fits into the drinking hole and helps secure the cover in a closed position. In other embodiments the base is further equipped with a ramp leading up to the drinking hole which guides the cover to the drinking hole and locks the stopper within the hole. In other embodiments a protective layer is provided over the base which is removed before use.
