Lid assembly with a rotary trigger for seal assembly and beverage container comprising the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beverage container lids lack flexibility in dispensing options, failing to provide users with the ability to selectively open and close multiple drink orifices while preventing spillage.
Innovation Solution
A lid assembly with a rotary trigger mechanism that allows for the selective opening and closing of multiple drink orifices and a gas vent, featuring a top plate that rotates to align with different orifices, a seal assembly for spill prevention, and a guide rail mechanism for pivotal movement of the drink and vent seals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lid includes multiple drink orifices for versatile beverage dispensing, then the adaptability is improved, but the device complexity increases due to the need for selective opening and closing mechanisms
Solution Approach 1:
The lid is segmented into multiple functional zones with separate drink orifices (first drink orifice for direct consumption, second drink orifice for straw usage) and a separate gas vent, each independently controllable through the rotary trigger mechanism. This segmentation allows versatile dispensing options while maintaining organized structural complexity
Solution Approach 2:
The rotary trigger mechanism provides dynamic control by allowing the top plate to rotate between multiple positions (first position aligning with first drink orifice, second position aligning with second drink orifice, third position aligning with gas vent), enabling selective opening and closing of different orifices based on user needs
2Ease of operation
If a lid provides selective opening of multiple orifices for flexibility, then the ease of operation is improved, but the reliability decreases due to potential spillage risks
Solution Approach 1:
The gas vent is positioned to be opened in advance during the rotation sequence, allowing pressure equalization to occur before the drink orifices are opened. This preliminary action prevents sudden pressure changes that could cause spillage, while maintaining ease of operation through the simple rotary motion
Solution Approach 2:
The rotary trigger mechanism acts as an intermediary control system that coordinates the opening sequence of different orifices. By controlling which orifice aligns with the opening at any given time, it ensures reliable spill-proof operation while providing easy user control through intuitive rotation
3Adaptability or versatility
If a lid includes a rotary trigger mechanism for selective orifice opening, then the adaptability is improved, but the device complexity increases due to additional moving parts
Solution Approach 1:
The rotary trigger mechanism serves multiple functions simultaneously: it selects which drink orifice is open, controls the gas vent opening, and provides a user interface for operation. This multi-functionality achieves versatile dispensing mode selection while minimizing the number of separate components needed
