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

VSEngineering 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

Engineering Contradiction:
Improvedrinking operationVSAvoidhot air spurring onto user
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improvegas vent mechanismVSAvoidgas vent function
Core Design Contradiction:
Device complexityVSReliability

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

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvehot air spurring onto userVSAvoidlid mechanism
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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.
