Solution Overview

Problem

Existing cosmetic containers lack ease of use, organization, and accessibility for multiple colors of eye powders and shadows, and often do not incorporate a detachable mirror compartment.

Innovation Solution

The invention introduces hingeless, magnetic swivel, and track system compacts that secure the base, tray, and lid without hinges, utilize magnetic attraction for closure, and employ a swivel pivot point with magnets, and a track system for tray movement, respectively, allowing for easy access and multiple positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If traditional hinged compacts are used, then the structure is simple and easy to manufacture, but the opening/closing mechanism is bulky and less elegant

Engineering Contradiction:
Improvecompact structureVSAvoidhinge mechanism
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent removes the hinge component entirely from the compact structure. Instead of using a traditional hinge to connect the lid and base, the invention employs a magnetic closure system where magnets embedded in the base attract corresponding magnetic elements in the lid, enabling the lid to attach and detach without any mechanical hinge. This extraction of the hinge component achieves a cleaner, more elegant design while maintaining functional closure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical hinge system with a magnetic field-based closure system. Magnets embedded in the base create magnetic attraction forces that hold the lid in place, eliminating the need for mechanical hinges, pins, or other moving parts. This substitution transforms the closure mechanism from mechanical to magnetic, achieving both simplicity and elegance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Stability of the object's composition

If multiple eye powder colors are stored in separate compartments, then organization is improved, but accessibility and ease of use deteriorates due to complex opening mechanisms

Engineering Contradiction:
Improvecosmetic organizationVSAvoidaccessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent divides the compact into multiple independent compartments or trays, each capable of holding different eye powder colors or cosmetic products. These segmented compartments are arranged within the base structure, allowing organized storage while maintaining easy access through the magnetic lid opening mechanism. Each compartment remains stable in its position while the overall structure allows quick access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The magnetic lid and base structure serves multiple functions simultaneously: it provides secure closure for the entire compact, allows easy opening for access to cosmetics, and supports the segmented compartment structure for organized storage. The universal magnetic closure system works regardless of which compartment is accessed, simplifying the user experience while maintaining organization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If a mirror is incorporated in the lid, then convenience is improved, but the mirror cannot be completely detached for cleaning or replacement

Engineering Contradiction:
Improvemirror convenienceVSAvoidmirror detachability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent separates the mirror from the lid structure, making the mirror a distinct, removable component rather than a permanently integrated element. The mirror can be completely detached from the lid for cleaning, replacement, or storage, while still providing convenience when attached during use. This segmentation allows the mirror to serve its function while maintaining adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mirror mounting system allows the mirror to transition between fixed and movable states. When attached to the lid, the mirror remains stable and functional during use. When needed for cleaning or replacement, the mirror can be easily detached and reattached, providing dynamic adaptability that combines the benefits of both permanent integration and complete removability.

Inventive Principle:
Principle #15Dynamics

AI summary

This application presents various containers for cosmetics: a hingeless compact, a compact with magnetic swivels and a compact with a track system. The hingeless compact has a first base portion with prong arms that pass through a second base portion and engage slots or engagement areas on a lid. A compact with magnetic swivels has base and a top that sandwich at least one inner tray; the inner tray is connected to the base and top at one swivel or pivot using an axis or peg; magnetic connections can keep the trays from being unintentionally opened. A compact with a track system allows movement of a tray from a first closed position to a second open position and allows for multiple intermediate positions along the length or travel of the track.
