Solution Overview

Problem

Cosmetic materials in their original packaging are bulky, inefficient to transport, and risk spoilage due to repeated opening and closing, especially when more material is carried than needed for a single application.

Innovation Solution

A modular cosmetic container assembly comprising a base with interchangeable inserts and a lid, where the inserts have varying numbers of wells for cosmetic materials, allowing for customizable and portable storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If cosmetic materials are transported in their original packaging, then the quantity of cosmetic material is sufficient for multiple applications, but the container becomes bulky and difficult to transport

Engineering Contradiction:

Improvequantity of cosmetic materialVSAvoidcontainer volume

Core Design Contradiction:

Quantity of substanceVSVolume of moving object

Solution Approach 1:

The original large container is divided into multiple smaller inserts, each containing a portion of the cosmetic material. These inserts can be individually removed and used, allowing the user to transport the full quantity of cosmetic material in a compact, organized manner that reduces overall container volume.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple inserts are nested within a single base container, with each insert fitting into its own designated space. This nesting arrangement allows the cosmetic material to be divided into separate portions while maintaining a compact overall form factor that is easier to transport than a single large container.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Quantity of substance

If a large quantity of cosmetic material is transported, then sufficient material is available for multiple applications, but the weight increases

Engineering Contradiction:

Improvequantity of cosmetic materialVSAvoidcontainer weight

Core Design Contradiction:

Quantity of substanceVSWeight of moving object

Solution Approach 1:

The cosmetic material is segmented into multiple smaller inserts that can be individually weighed and portioned. This allows the user to transport only the necessary quantity for the intended applications, reducing overall weight while maintaining sufficient material supply.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the original container is opened and closed repeatedly, then access to cosmetic material is enabled, but spoilage risk increases

Engineering Contradiction:

Improveaccess to cosmetic materialVSAvoidshelf-life of cosmetic material

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The cosmetic material is divided into multiple sealed inserts, each maintaining its own integrity. The user only needs to open the specific insert they are using, rather than repeatedly opening and closing a single large container. This segmentation minimizes exposure of the cosmetic material to air and contaminants, reducing spoilage risk.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cosmetic material is pre-portioned into separate inserts before use, with each insert sealed to preserve freshness. This preliminary segmentation allows the user to access only the needed portion without compromising the integrity of the remaining material, thereby extending shelf-life.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If cosmetic materials are sorted through in original packaging, then all materials are accessible, but the process becomes inefficient

Engineering Contradiction:

Improveaccess to all cosmetic materialsVSAvoidsorting efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

Different cosmetic materials are placed in separate, labeled inserts within the base container. This segmentation allows the user to quickly identify and access the specific insert containing the desired material without having to sort through a single large container, significantly improving sorting efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each insert is designed with specific characteristics (such as labeling, transparency, or shape) that correspond to the cosmetic material it contains. This local differentiation allows for rapid identification and access to specific materials based on their location and visual cues, enhancing productivity.

Inventive Principle:

Principle #3Local quality

AI summary

A modular cosmetic container assembly includes a base having a bottom wall and a plurality of sidewalls defining an insert receiving space, and a plurality of inserts removably insertable into the insert receiving space. Each of the inserts has a same plurality of outer dimensions and at least one well. The inserts differ in a number of the wells in each of the inserts. The insert receiving space is sized to receive at least two of the plurality of inserts that are all interchangeably positionable in the insert receiving space.
