Solution Overview

Problem

Existing cosmetic packaging with integrated soft applicators becomes dirty quickly and is not easily replaceable, leading to a short lifespan.

Innovation Solution

A packaging design with a deformable tank and a detachable dispenser system, where the soft applicator is housed in a removable first body that can be easily replaced, allowing the applicator to be cleaned or swapped.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the packaging includes an integrated soft applicator that directly receives cosmetic product from the tank, then the applicator is readily accessible and easy to use, but the applicator gets dirty quickly and cannot be easily replaced

Engineering Contradiction:
Improveapplicator accessibilityVSAvoidapplicator longevity
Core Design Contradiction:
Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The applicator is segmented from the tank by introducing an intermediate element (conduit with support surface) between them. The applicator remains integrated with the packaging structure but is no longer in direct contact with the cosmetic product flow, thereby reducing contamination while maintaining accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An intermediate element consisting of a conduit with a support surface is introduced between the tank and the applicator. This intermediary component receives the cosmetic product from the tank and transfers it to the applicator, preventing direct contact and reducing dirt accumulation on the applicator.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the soft applicator is bound to the tank, then the structure is simple and compact, but the applicator cannot be easily replaced when dirty

Engineering Contradiction:
Improvepackaging structureVSAvoidapplicator replaceability
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The applicator assembly is segmented into separable components: the first body containing the applicator can be detached from the tank assembly. This segmentation enables easy replacement of the applicator while maintaining overall structural simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between the applicator assembly and tank is made dynamic rather than fixed. The removable first body allows the applicator to be easily detached and replaced, transforming the static bound structure into a dynamic, replaceable configuration.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the applicator is in direct contact with the cosmetic product exit duct, then the product transfer is efficient, but the applicator contaminates quickly and requires frequent replacement

Engineering Contradiction:
Improveproduct transfer efficiencyVSAvoidapplicator contamination
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

A conduit with a support surface is introduced as an intermediary between the product exit duct and the applicator. The conduit receives product directly from the tank and presents it to the applicator on its support surface, maintaining efficient product transfer while preventing direct contamination of the applicator.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The applicator is extracted from direct contact with the cosmetic product flow. By removing the applicator from the direct product path and placing it in contact only with the support surface of the conduit, the source of contamination is eliminated while product transfer efficiency is maintained through the conduit's support surface.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A packaging (1) for cosmetics is provided, comprising a tank (2) adapted to contain a cosmetic product in liquid or pasty form; a dispenser (3) adapted to convey the cosmetic product from the tank (2) to an environment external to the tank (2) and including at least a rigid conduit (4) in fluid open connection with the tank (2) and developing along a main axis (4a) defining the through-channel (42), and a first body (5) at least partially soft adapted to allow the application of the cosmetic product onto the skin; wherein the conduit (4) includes a support surface (40) positioned at a free end of the conduit (4) to collect the cosmetic product exiting from the channel (42), and the first body (5) is distinct from the conduit (4) and includes a peripheral recess (50) configured to accommodate the conduit (4) and removably mutually bind the first body (5) and the conduit (4) when the conduit (4) is introduced into the recess (50).
