Cosmetic Container Inner Wall Product Storage

Solution Overview

Problem

Cosmetic product applicators, such as mascara pens, face issues with product wastage and drying due to the applicator being immersed in the container, leading to inefficient use and reduced product lifespan.

Innovation Solution

A cosmetic product container design where the product is stored on the inner wall, away from the applicator, with controlled openings and a valve system to prevent air exposure, allowing precise product delivery to the applicator without excessive loading or exposure to ambient air.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the applicator is immersed in the product inside the container in the retracted position, then the article can be used with a single hand for make-up, but the applicator comes out of the case loaded with a large quantity of product of which a significant part is not used for make-up

Engineering Contradiction:

Improvesingle hand useVSAvoidproduct wastage

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The applicator is extracted from the product container, eliminating direct contact between the applicator and the product reservoir. The applicator is mounted on the cap rather than immersed in the product, so it only contacts product during the brief moment of application, not during storage or transport.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The device is segmented into separate functional components: the product container, the applicator, and the cap. The applicator is attached to the cap rather than being integrated with the product container, allowing independent control of product storage and application functions.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the applicator is immersed in the product inside the container in the retracted position, then the article can be used with a single hand for make-up, but product in contact with air dries more quickly which reduces the lifetime of the article

Engineering Contradiction:

Improvesingle hand useVSAvoidproduct lifespan

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The applicator is extracted from the product container, eliminating the continuous exposure pathway for air to enter the container. By mounting the applicator on the cap rather than immersing it in the product, the container remains sealed and protected from air exposure during non-use periods.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If the applicator is immersed in the product inside the container, then the article can be used with a single hand for make-up, but entry of air into the container tends to dry the product more quickly and reduces the lifetime of the product inside the container
