Solution Overview

Problem

Conventional cosmetic storage containers are typically designed for one-time use, leading to waste and inefficiency, as they are discarded once the cosmetic product is depleted, rather than being refillable or reusable.

Innovation Solution

A refillable cosmetic container device featuring an exterior body and an inner capsule that can be replaced, with a removable outer cap and end cap, including fixation devices and a wiper to secure the inner capsule, allowing for easy refilling and reuse of the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If cosmetic containers are designed for one-time use, then manufacturing and operation are simplified, but waste increases and cost-effectiveness deteriorates

Engineering Contradiction:
Improvecontainer manufacturing simplicityVSAvoidcosmetic waste
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The container is divided into two main segments: a reusable exterior body and a replaceable inner capsule. The inner capsule contains the cosmetic product and can be removed and replaced independently, allowing the exterior body to be reused while only the consumed capsule is discarded. This segmentation reduces waste compared to complete container disposal while maintaining manufacturing simplicity for each component.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables selective discarding of only the inner capsule after cosmetic product depletion, while the exterior body is recovered and reused for subsequent capsules. This partial discarding approach significantly reduces material waste compared to disposing of the entire container, while the exterior body's durable construction ensures it can be reused multiple times.

Inventive Principle:
Principle #34Discarding and recovering

2Loss of substance

If cosmetic containers are made reusable with replaceable inner capsules, then waste is reduced and cost-effectiveness improves, but device complexity increases

Engineering Contradiction:
Improvecosmetic wasteVSAvoidcontainer structure complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The container structure is segmented into an exterior body and an inner capsule with distinct functions. The inner capsule includes a cosmetic product container and a closure, while the exterior body provides structural support and dispensing mechanisms. This clear segmentation simplifies the replacement process compared to more complex modular systems, as users only need to remove and replace the inner capsule without disassembling complex mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner capsule is nested within the exterior body, with the capsule fitting into a designated cavity in the exterior body. This nesting arrangement provides a compact, space-efficient design that minimizes the overall container size while enabling easy removal and replacement of the inner capsule. The nested structure avoids the need for complex fastening mechanisms, thereby reducing device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If inner capsules are securely fixed to prevent accidental removal, then reliability improves, but ease of operation deteriorates

Engineering Contradiction:
Improvecapsule retention securityVSAvoidcapsule removal ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fixation mechanism employs a dynamic balance between retention strength and release ease. The inner capsule is secured to the exterior body through a simple snap-fit or friction-based connection that provides sufficient holding force during normal use and transport (improving reliability), but can be easily detached by applying slight manual force or twisting motion (maintaining ease of operation). This dynamic characteristic allows the system to adapt between two opposing requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fixation mechanism is designed to be self-latching during assembly, where the inner capsule automatically secures itself to the exterior body upon insertion without requiring additional fastening steps (improving reliability). For removal, the design allows simple manual intervention such as pressing a release tab or applying slight force to disengage the connection (maintaining ease of operation). This self-service approach eliminates complex locking mechanisms while ensuring secure retention.

Inventive Principle:
Principle #25Self-service

AI summary

A cosmetic container device includes an exterior body and an inner capsule for storing a cosmetic product. The inner capsule may be received in the exterior body. An outer cap removably coupled to a first end of the exterior body may include an application device for removing and applying the cosmetic product stored within the inner capsule. The cosmetic container device may further include an end cap removably coupled to a second end of the exterior body. The cosmetic container device may further include one or more fixation devices for removably securing the inner capsule to the end cap. Removal of the end cap from the exterior body may allow the inner capsule to be removed from the exterior body, so that the cosmetic container device can be refilled by replacing the inner capsule.
