Lockable Beverage Lid With Dual Locking for Spill Prevention
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 dropped, or require constant user intervention to maintain closure, failing to provide a secure and convenient drinking experience.
Innovation Solution
A lid with a dual-locking mechanism, featuring a rotatable actuation disk and a press-button lock, which ensures the drinking spout and vent hole are sealed unless both mechanisms are in the unlocking position, providing secure closure and controlled fluid passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a solid unitary lid without openings is used, then spill prevention is improved, but ease of operation deteriorates as users must remove the lid to drink
Solution Approach 1:
The lid is divided into separate functional components: a body with aperture, a removable plug, and a cover. This segmentation allows the aperture to remain open for easy drinking while the plug and cover can seal the aperture when not in use, preventing spills without requiring complete lid removal.
Solution Approach 2:
The lid transitions from a static solid structure to a dynamic system with movable parts. The plug can be inserted or removed from the aperture, and the cover can rotate between open and closed positions, allowing the lid to adapt between open (easy drinking) and closed (spill prevention) states.
2Ease of operation
If unobstructed apertures are provided in the lid, then ease of operation is improved, but spill risk increases when the vessel is tipped or dropped
Solution Approach 1:
The plug is designed to be preliminarily positioned in the aperture to seal it. When the vessel is tipped or dropped, the plug remains in place (secured by the retention groove), preventing spills before they can occur, while still allowing easy access when intentionally opened.
Solution Approach 2:
The plug acts as an intermediary element between the open aperture and the sealed state. It can be easily inserted or removed by the user, providing a simple mechanism to prevent spills during accidental tipping while maintaining ease of operation when drinking is intended.
3Object-affected harmful factors
If a means for selectively opening and closing apertures is added, then spill prevention is improved, but device complexity increases
Solution Approach 1:
The closure mechanism is segmented into simple, independent components: a plug that fits into the aperture and a cover that rotates into place. Each component has a single, clear function, avoiding complex mechanical systems while achieving reliable spill prevention through straightforward assembly and disassembly.
4Reliability
If a dual-locking mechanism is implemented, then reliability of closure is improved, but device complexity increases
Solution Approach 1:
The dual-locking mechanism is segmented into two independent, simple locking features: the retention groove that secures the plug, and the snap-fit engagement between the cover and body. Each locking feature is a separate, straightforward mechanical element rather than a complex integrated system, reducing overall complexity while maintaining high reliability.
Solution Approach 2:
The retention groove is designed with dimensions that provide a interference fit with the plug, creating a locking effect that prevents accidental dislodgement. This beforehand designed geometric constraint ensures the plug remains secured during normal use and accidental tipping, enhancing reliability without adding complex locking mechanisms.

AI summary
A lid for use with a beverage container. The lid has a body with a drink opening, a drink opening stopper operable to transition between a closed position and an opened position, and a lock actuator manually rotatable between a locking position preventing the drink opening stopper from transitioning from the closed position to the opened position when the lock actuator is in the locking position and an unlocking position permitting the drink opening stopper to transition from the closed position to the opened position when the lock actuator is in the unlocking position.
