Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If no overflow prevention structure is provided, then the device complexity is reduced, but the measurement precision of overflow detection deteriorates
Solution Approach 1:
The patent replaces complex mechanical overflow detection structures with a simple conductive ring structure that utilizes electrical conduction properties. The detection ring (100) with detecting portion (30) and lead connecting structure (50) creates an electrical circuit that opens when food materials contact it, substituting mechanical sensors with an electrical detection mechanism that is both simple and precise.
2Measurement precision
If an overflow prevention structure is added, then the measurement precision of overflow detection is improved, but the device complexity increases
Solution Approach 1:
The patent merges the detection ring (100) directly with the cup lid assembly through integrated mounting slots (2044, 2046) in the lower lid (204). The annular body (10) and lead connecting structure (50) are combined into a single component that can be mounted as one unit, eliminating the need for separate mounting structures and reducing overall device complexity while maintaining detection precision.
Solution Approach 2:
The detection ring (100) serves multiple functions: it acts as an overflow detection sensor, provides electrical conduction path through the lead connecting structure (50), and integrates with the cup lid assembly structure. This multi-functionality reduces the need for additional components and simplifies the overall device design.
3Device complexity
If the overflow prevention structure position is unreasonable, then the device complexity is reduced, but the measurement precision of overflow detection deteriorates
Solution Approach 1:
The detection ring (100) is pre-positioned at the optimal location on the cup lid assembly, specifically at the peripheral edge of the feeding port (2042) where overflow most commonly occurs. The mounting slots (2044, 2046) are pre-designed in the lower lid (204) to accommodate the ring at this critical position, ensuring accurate detection before overflow can occur while maintaining simple integration.
