Leaktight Cosmetic Compartment With Segmented Closure Cap

Solution Overview

Problem

Existing cosmetic product packaging devices are either complex to manufacture, not very leaktight, or both, which complicates storage, transport, and application, and fails to ensure hygiene and product preservation.

Innovation Solution

A compact, leaktight container with separate compartments and a detachable closure cap that ensures each compartment remains sealed, allowing for the storage and transport of multiple cosmetic products without mixing, using thermoplastic materials and a sealing lip for leaktightness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing cosmetic packaging devices are used, then they can store multiple products, but they are not very leaktight and products may mix or leak

Engineering Contradiction:

ImproveleaktightnessVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The container is divided into multiple separate compartments, each capable of being independently closed with its own closure cap. This segmentation allows each compartment to be sealed individually, ensuring leaktightness for each product while maintaining a relatively simple overall device structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The applicator is stored within one of the compartments of the container. This nesting arrangement allows the applicator to be kept separate from the cosmetic products until use, while still being part of the compact device structure, without requiring additional external storage space.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of manufacture

If existing cosmetic packaging devices are used, then they can store multiple products, but they are complicated to manufacture and expensive

Engineering Contradiction:

Improveease of manufactureVSAvoidleaktightness

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The container is divided into multiple separate compartments, each capable of being independently closed with its own closure cap. This segmentation allows each compartment to be sealed individually, ensuring leaktightness for each product while maintaining a relatively simple overall device structure.

3Volume of moving object

If existing cosmetic packaging devices are used, then they can store products and applicators, but they take up too much space and are not practical to use

Engineering Contradiction:

Improvedevice volumeVSAvoidease of operation

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The applicator is stored within one of the compartments of the container. This nesting arrangement allows the applicator to be kept separate from the cosmetic products until use, while still being part of the compact device structure, without requiring additional external storage space.
