Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotating latching portion and stationary latching groove structure with transmission mechanism is used, then the cup lid can open and close the liquid flow path, but the structure becomes very complex and requires high precision making it difficult to assemble
Solution Approach 1:
The patent extracts the complex transmission mechanism from the system and replaces it with a direct rolling body mechanism. The rolling body directly controls the latching portion without requiring intermediate transmission components, thereby simplifying the overall structure while maintaining the ability to control the liquid flow path.
Solution Approach 2:
Instead of using a rotating latching portion with a complex transmission mechanism, the patent inverts the approach by using a sliding upper lid that directly moves the rolling body through aligned through holes. This inversion eliminates the need for rotational motion and complex transmission components.
2Reliability
If a complex transmission structure with multiple portions is used, then the cup lid can control the latching mechanism, but it is prone to jamming during use resulting in poor operation
Solution Approach 1:
The patent segments the latching control function into simple, independent components: the rolling body, the through holes, and the latching portion. Each component has a single, clear function, eliminating the interconnected complexity that causes jamming in traditional transmission structures.
Solution Approach 2:
The patent replaces the mechanical transmission system with a simpler rolling body mechanism that uses the alignment of through holes to control movement. This substitution eliminates multiple mechanical linkages that are prone to jamming, resulting in smoother operation.
3Reliability
If high precision manufacturing is used for the complex structure, then the cup lid can function properly, but the manufacturing cost and difficulty increase
Solution Approach 1:
The patent changes the design parameters from requiring high-precision rotational alignment to simpler linear alignment of through holes. The rolling body diameter and hole dimensions are designed to allow easy assembly without requiring high-precision manufacturing, while still ensuring proper function.
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
The design ensures convenient mounting and dismounting, secure sealing, and easy operation with a simple structure that reduces assembly complexity and prevents jamming.
Implementation Method 1
a rolling body is arranged between the push-press portion and the first through hole; when the upper lid is pressed downward, the first through hole is aligned and communicated with the second through hole or the groove, such that the rolling body rolls at an interpenetration of the first through hole and the second through hole or the groove
Implementation Method 2
the inner lid is elastically connected to the upper lid

AI summary
A press-type cup lid comprises an upper lid, an inner lid, and a hollow outer lid. The inner lid is fixedly connected to the outer lid, and upper lid is slidably connected to outer lid; at least two first through holes are uniformly arranged on a wall of the inner lid, the upper lid is provided with push-press portion, and receiving space for receiving the push-press portion is formed between wall of inner lid and wall of outer lid. A second through hole or a groove is formed on push-press portion; the second through hole or groove corresponds to the first through hole in position; when upper lid is pressed downward, the first through hole is aligned and communicated with the second through hole or groove, such that rolling body rolls at an interpenetration of the first through hole and the second through hole or groove.
