Solution Overview

Problem

Existing container stoppers for storing auxiliary granular contents are complicated to manufacture and difficult to recycle due to internal contamination.

Innovation Solution

A container stopper with a simplified structure featuring a stopper body and an upper cover that form an auxiliary space, using a partition wall to divide the space vertically, allowing for easy assembly and disassembly, and incorporating a sealing mechanism to prevent contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a plurality of members are coupled to each other to store auxiliary granular contents, then the auxiliary contents can be stored, but the manufacture becomes complicated

Engineering Contradiction:

Improveauxiliary contents storageVSAvoidstructure complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent integrates the auxiliary content storage function directly into the stopper body by forming an auxiliary content holding space within the stopper structure itself, rather than using separate coupled members. This merging of functions simplifies the overall structure while maintaining the capability to store auxiliary granular contents alongside the main liquid content

Inventive Principle:

Principle #5Merging (Combining)

2Quantity of substance

If a plurality of members are coupled to each other to store auxiliary granular contents, then the auxiliary contents can be stored, but recycling becomes inconvenient or impossible due to internal contamination

Engineering Contradiction:

Improveauxiliary contents storageVSAvoidrecycling convenience

Core Design Contradiction:

Quantity of substanceVSEase of manufacture

Solution Approach 1:

The stopper and container are designed as integrated structures where the auxiliary content holding space is formed within the stopper body itself. This integration allows the entire stopper-container assembly to be recycled together as a single unit, avoiding the contamination issues that would arise from disassembling and recycling multiple separate members

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If a simplified structure is used for the container stopper, then manufacturing becomes easier, but the functionality to store and dispense auxiliary contents may be compromised

Engineering Contradiction:

Improvestructure simplicityVSAvoidauxiliary content functionality

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The stopper body is designed to perform multiple functions: sealing the container, storing auxiliary granular contents, and dispensing both liquid and auxiliary contents through a unified discharge mechanism. This multi-functionality is achieved through the integrated auxiliary content holding space and the discharge hole system that handles both liquid and granular materials, eliminating the need for separate storage and dispensing mechanisms

Inventive Principle:

Principle #6Universality (Multi-functionality)
