Solution Overview
Problem
Existing hot cup lid systems fail to provide a safe, clean, convenient, and economical solution for drip-free drinking of hot liquids, often being costly, difficult to manufacture, and lacking durability.
Innovation Solution
A hot cup lid system with a thick-walled well section and a drink hole, designed for efficient coupling with cups, fabricated from plastic with specific dimensional configurations to ensure secure and leak-proof sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing hot cup lid systems are used, then covering and drinking functions are provided, but they fail to provide drip-free drinking and are costly and difficult to manufacture
Solution Approach 1:
The lid is divided into distinct functional sections: a well section for containing liquid, walls providing structural support, and a drink hole for consumption. This segmentation allows each part to be optimized for its specific function while simplifying the overall manufacturing process through modular design
Solution Approach 2:
The walls are designed with greater thickness specifically in regions where structural integrity and sealing are critical, while other regions of the lid maintain standard thickness. This localized reinforcement ensures drip-free performance at key areas without unnecessarily increasing overall manufacturing complexity
2Duration of action of stationary object
If existing hot cup lid systems are used, then covering function is provided, but they lack durability and are costly
Solution Approach 1:
The wall thickness parameter is increased in critical regions to enhance durability and extend the lid's service life. This parameter change is strategically applied only where needed for durability, avoiding unnecessary material usage and keeping manufacturing costs controlled
3Strength
If thick-walled well section is used, then durability and sealing are improved, but material usage increases
Solution Approach 1:
The thick-walled well section is implemented specifically in the regions where strength and sealing are most critical, while other parts of the lid maintain standard wall thickness. This localized approach ensures the lid achieves the necessary strength for durability without unnecessarily increasing overall material consumption

AI summary
A lid has a generally planar top with a front and a rear and sides there between. The planar top is circular with a center. The planar top includes a well section. Walls bound the well section. The walls extend upwardly from a location between the front and the center of the planar top. The walls have a thickness greater than all other regions of the lid. A drink hole is formed in the well section.
