Modular Cosmetic Packaging With Reusable Magnetic Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic packaging devices require complete replacement when parts need to be changed, especially with sophisticated closure mechanisms, leading to high costs.
Innovation Solution
A modular packaging design allowing partial replacement of components, such as the container and applicator, using thread-based coupling mechanisms and magnets for easy assembly and disassembly, while maintaining outer casings intact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete replacement of the device is performed when components need to be replaced, then all components are renewed, but the cost increases significantly
Solution Approach 1:
The applicator device is divided into separate modular components: a reusable outer casing and replaceable internal components (container and applicator). This segmentation allows individual components to be replaced without replacing the entire device, reducing replacement costs while maintaining functionality.
2Reliability
If sophisticated closure mechanisms are included in the device, then sealing performance is improved, but the complexity of the device increases
Solution Approach 1:
The closure mechanism is integrated into the outer casing as a separate module, while the container and applicator components have simplified or eliminated closure mechanisms. This segmentation concentrates the complex sealing function in one reusable component, maintaining sealing performance while reducing overall device complexity.
3Reliability
If the entire device is replaced when parts need changing, then all components are renewed, but waste increases and costs rise
Solution Approach 1:
The device is segmented into reusable and disposable components. The outer casing with closure mechanism is designed for reuse, while internal components like containers and applicators can be replaced independently. This reduces material waste by keeping functional components in use longer.
Solution Approach 2:
The modular design enables selective discarding of consumed or damaged internal components while recovering and reusing the outer casing and closure mechanism. This extends the lifecycle of durable components and reduces overall waste.
4Ease of operation
If modular design with easy assembly/disassembly is implemented, then component replacement becomes easier, but device complexity increases
Solution Approach 1:
The coupling between components uses simple magnetic attraction instead of complex mechanical fastening systems. This allows easy assembly and disassembly by simply bringing components together or pulling them apart, providing modular functionality without significantly increasing device complexity.

AI summary
Packaging (1) for a cosmetic suitable for allowing application of a cosmetic product (10) on a user's body, defining a main axis (1a) and comprising: a container (2) suitable for containing the product (10) and including an internal volume (21) extending along the main axis (1a) and a first opening (20) for accessing the internal volume (21); an applicator (3) for the product (10), comprising: an application head (30) suitable for being immersed in the product (10), for retaining part of the product (10) and for allowing application of the product (10) on the body; an obstruction portion (31) suitable for reversibly obstructing the access to the first opening (20), defining an obstruction position when positioned at said first opening (20); a stem (32) extending along the main axis (1a), integral with the head (30), constrained to the obstruction portion (31) at its own end opposite to the head (30) and configured at least to support the head (30) to facilitate insertion of the head (30) into the internal volume (21) and extraction of the head (30) from the internal volume (21) for the application; a first tubular body (5) and extending along the main axis (1a), reversibly shod around the container (2) in such a way that one end of the container (2) at the opening protrudes from the first body (5); a second tubular body (6) and extending along the main axis (1a), reversibly shod around the obstruction portion (31); constraint means (4) integral in part with the first body (5) and in part with the second body (6), and configured to reversibly constrain the first body (5) to the second body (6) by blocking the obstruction portion (31) in the obstruction position.
