Drinking Container Lid Assembly with Sequential Gas Vent Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking containers often allow hot air to escape through the drinking orifice along with the liquid, causing discomfort, and may require additional steps or fail to open the gas vent before drinking, leading to ineffective ventilation.
Innovation Solution
A lid assembly with a mechanism that ensures the drinking orifice can only be opened after the gas vent is opened, featuring a piston and lever system where the piston's movement is restricted until the closure member opens the gas vent, ensuring hot air escapes before drinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gas vent and drinking orifice are opened simultaneously, then the drinking orifice can be opened for drinking, but hot air rushes out through the drinking orifice causing discomfort
Solution Approach 1:
The gas vent is opened in advance before the drinking orifice through a sequential opening mechanism. The lid includes a gas vent opening and a drinking orifice opening that operate in sequence, allowing hot air to escape through the gas vent first before the user drinks from the drinking orifice, thus preventing hot air from spurting onto the user's face
2Device complexity
If the gas vent requires manual opening by the user, then the gas vent structure can be simple, but the user may forget to open it disabling the ventilation function
Solution Approach 1:
The lid assembly automatically performs the function of opening the gas vent without requiring user intervention. The sequential opening mechanism is designed such that when the user opens the lid, the gas vent opening activates first automatically, ensuring the ventilation function is always performed correctly without relying on user memory or additional operations
3Object-affected harmful factors
If a sequential opening mechanism is implemented to open gas vent first, then hot air can escape before drinking, but the mechanism complexity increases
Solution Approach 1:
The sequential opening mechanism merges the gas vent opening and drinking orifice opening functions into a single integrated lid assembly. The mechanism uses a unified structure where the closure member and lid body work together to automatically sequence the opening of both vents, reducing the need for separate independent mechanisms while achieving the desired sequential operation
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
Prevents hot air from spouting onto the user by ensuring the gas vent is open before the drinking orifice, enhancing user comfort and ensuring proper ventilation during consumption of hot liquids.
Implementation Method 1
a closure member pivotally mounted on a top surface of the upper lid member for pivotal movement to close and open the gas vent
Implementation Method 2
a piston movable within the upper lid member in a direction in order to pivotally move the lever downwardly so that the baffle plate moves away from the drinking orifice
Implementation Method 3
a torsion spring may be provided to constantly apply an upward pressure to the lever
Implementation Method 4
a piston spring may be provided to constantly apply an outward pressure to the piston head
