Dual-Locking Beverage Lid for Spill-Resistant Drinking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lids for liquid storage vessels either lack control over fluid exit, leading to potential spills when tipped, or have always-open apertures that do not provide insulation or secure closure.
Innovation Solution
A lid with a dual-locking mechanism, including a rotatable actuation disk and a press-button lock, that selectively opens and closes a drinking spout and vent hole using a hinge mechanism and flexible plugs, ensuring fluid passage only when both locks are in the unlocking position, providing secure closure and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lid includes unobstructed apertures for liquid exit, then ease of operation is improved, but reliability deteriorates due to potential spills when the vessel is inadvertently tipped or dropped
Solution Approach 1:
The lid employs a dynamic occlusion member that can move between open and closed positions, allowing the aperture to transition from unobstructed to blocked. This dynamic element enables the system to adapt its state based on operational needs, providing full access during intentional use while preventing unintended flow
Solution Approach 2:
An intermediary occlusion member is introduced between the liquid contents and the aperture. This mediator component selectively blocks or permits liquid passage, serving as a buffer that prevents direct exposure of the aperture while maintaining the capability for controlled access when activated
2Reliability
If a lid includes a means for selectively opening and closing apertures, then reliability is improved by preventing spills, but device complexity increases due to additional locking mechanisms
Solution Approach 1:
Multiple locking functions are merged into a single integrated occlusion member that combines sealing, blocking, and positioning capabilities. This consolidation reduces the number of separate components and simplifies the overall mechanism while maintaining reliable selective closure
Solution Approach 2:
The occlusion member serves multiple functions simultaneously: it seals the aperture, blocks liquid passage, and can be actuated by various input methods. This multi-functionality reduces the need for separate dedicated components for each function, thereby simplifying the device
3Loss of substance
If a lid closes apertures to maintain contents inside the vessel, then loss of substance is reduced, but ease of operation deteriorates as the user must manually open the aperture to drink
Solution Approach 1:
The occlusion member is designed as a dynamic component that can rapidly transition between closed and open states. This dynamic capability allows the system to maintain closure for content retention while enabling quick, easy access when the user intends to drink, eliminating the need for complex manual opening procedures

AI summary
A beverage container closure or lid that is adapted for closing an open end of a beverage container is provided. The lid is selectively couplable to the beverage container and includes a selectively openable cover that, when closed, creates a fluid-tight seal between the beverage container and the environment. The lid is provided with a dual-locking mechanism including an actuation disk locking mechanism and a press-button locking mechanism. Each locking mechanism is operable to transition between a locking position and an unlocking position and opening the cover to permit the passage of fluid requires that both locking mechanism be in their respective unlocking positions.
