Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Beverage containers with vent holes to prevent pressure-related leakage face issues with accurate vent blocking, leading to potential leaks when in motion or when the vent valve malfunctions, and existing solutions require complex operations to release pressure.

Innovation Solution

A beverage container design featuring a vent blocking portion with a ventilation adjusting protruding portion that enlarges a slit portion upon cancellation operation, ensuring continuous pressure release and preventing leaks, integrated with a spout blocking mechanism to prevent beverage squirtage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a vent hole is formed in the lid to release pressure, then beverage squirtage through the straw is prevented, but beverage leakage occurs when the container is carried in a bag

Engineering Contradiction:

Improvebeverage squirtage through strawVSAvoidbeverage leakage

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The vent hole is equipped with a movable blocking member that can dynamically switch between blocking and unblocking states. When the outer lid is closed, the blocking member blocks the vent hole to prevent leakage. When the outer lid is opened, the blocking member moves to unblock the vent hole to prevent squirtage, enabling adaptive response to different usage conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The blocking member is designed to automatically move based on the state of the outer lid engagement. The mechanical connection between the lid engagement mechanism and the blocking member allows the system to self-regulate the vent hole blocking state without requiring manual intervention, switching between blocked and unblocked states according to whether the lid is closed or opened

Inventive Principle:

Principle #25Self-service

2Object-generated harmful factors

If a protruding portion is used to block the vent hole, then beverage leakage is prevented, but the protruding portion may be displaced and fail to accurately block the vent

Engineering Contradiction:

Improvebeverage leakageVSAvoidvent blocking accuracy

Core Design Contradiction:

Object-generated harmful factorsVSReliability

Solution Approach 1:

The blocking member is nested within the vent hole structure, with the inner lid portion providing a recess that receives the blocking member. This nested arrangement ensures the blocking member remains properly positioned within the vent hole and cannot be easily displaced, maintaining reliable blocking accuracy

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The blocking member utilizes elastic deformation through curved or flexible structures. The elastic member can deform to engage with the vent hole geometry and return to its original position, ensuring consistent and accurate blocking without displacement, while the elastic force maintains reliable contact

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Object-generated harmful factors

If the vent hole is blocked when the outer lid is closed, then beverage leakage is prevented, but pressure accumulates in the container

Engineering Contradiction:

Improvebeverage leakageVSAvoidpressure in container

Core Design Contradiction:

Object-generated harmful factorsVSStress or pressure

Solution Approach 1:

The blocking member is designed to prevent beverage leakage by blocking the vent hole when the outer lid is closed. The spout blocking portion simultaneously blocks the spout to counteract the pressure buildup, preventing beverage discharge while allowing pressure to accumulate safely without causing leakage

Inventive Principle:

Principle #9Preliminary anti-action

4Adaptability or versatility

If a valve structure is used in the vent hole, then ventilation operation is enabled, but the beverage may leak if the valve malfunctions

Engineering Contradiction:

Improveventilation operationVSAvoidbeverage leakage prevention

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The complex valve structure is replaced by a simpler blocking member mechanism that is integrated into the vent hole. This extracted and simplified design eliminates the complexity and potential failure points of traditional valves while maintaining the essential ventilation function when needed and providing reliable blocking when required

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A beverage container includes a container main body, an inner lid portion that covers the container main body, a spout portion which is formed on the inner lid portion and through which a beverage is discharged, a spout blocking portion 3a that blocks the spout portion, an outer lid portion disposed so as to be able to engage with and disengage from the inner lid portion, a ventilation portion that allows air to flow between the inside and the outside of the container main body, and a vent blocking portion formed on the outer lid portion or the inner lid portion to block the ventilation portion when the outer lid portion is placed to close the inner lid portion. A cancellation operation portion which cancels engagement between the outer lid portion and the inner lid portion is formed, and the beverage container further includes a ventilation adjusting protruding portion.
