Cup lid and cup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cup lids with ball-nose spouts are difficult to replace, leading to hygiene issues due to the inconvenience of cleaning and replacing the suction nozzle.
Innovation Solution
A cup lid design featuring a detachable elastic mounting base with a switch component that allows the ball-nose to rotate between open and closed positions, facilitating easy disassembly and replacement of the suction pipe, which includes a suction nozzle and inner pipe body, ensuring good sealing and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spout with ball-nose is fixed to the lid body via pins, then the structure is stable and reliable, but the spout becomes difficult to replace and clean
Solution Approach 1:
The spout assembly is divided into separate components: the spout body, the ball-nose, and the mounting base. This segmentation allows the spout to be easily detached and replaced by simply removing the mounting base, while maintaining structural stability when assembled. The mounting base can be independently removed from the lid body, enabling convenient cleaning and replacement of the spout components.
2Reliability
If the ball-nose is inserted into a spherical groove and hinged with pins, then the switch mechanism is reliable, but the entire spout assembly becomes difficult to disassemble
Solution Approach 1:
The internal structure is segmented into the mounting base and the lid body. The complex hinged mechanism with pins and spherical groove is contained within the mounting base, which can be removed as a single unit. This allows the complex mechanism to remain intact and reliable while simplifying disassembly - users only need to remove the mounting base rather than disassemble the entire spout assembly and its internal mechanisms.
Solution Approach 2:
The mounting base containing the ball-nose and hinged mechanism is extracted as a separate removable component from the lid body. This extraction allows the complex internal mechanism to be accessed, cleaned, or replaced by simply removing the mounting base, without requiring disassembly of the lid body or the sealing cover.
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 enables convenient cleaning and replacement of the suction nozzle, maintaining hygiene and reducing replacement costs while ensuring smooth drinking and leak prevention.
Implementation Method 1
a mounting chamber provided at the lid body, the mounting chamber is detachably provided with an elastic mounting base
Implementation Method 2
the ball-nose is configured to divide the first channel into an upper channel and a lower channel, the ball-nose has a second channel, the switch component has an open position and a closed position; when the switch component is in the open position, the second channel communicates the upper channel with the lower channel
