Solution Overview

Problem

Existing jewelry cases fail to prevent tangling and co-mingling of necklaces and bracelets while allowing for easy display and secure storage, often requiring upright positioning or using space-consuming compartments.

Innovation Solution

A portable jewelry case with compression bars that securely hold jewelry in place within individual compartments, allowing vertical or horizontal storage and transport, featuring a transparent lid and locking mechanism to prevent tangling and co-mingling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If necklaces are allowed to hang freely for display, then viewing and access are improved, but tangling and co-mingling of jewelry occurs

Engineering Contradiction:

Improveviewing and accessVSAvoidjewelry organization

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The jewelry case is divided into multiple individual compartments, each capable of holding a single necklace or piece of jewelry. This segmentation prevents different necklaces from tangling with each other while still allowing easy viewing and access to each item through the transparent lid and individual compartment design.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If smaller divided compartments are used to prevent tangling, then jewelry organization is improved, but space is consumed and items can still shift or tangle with themselves

Engineering Contradiction:

Improvejewelry organizationVSAvoidcase volume

Core Design Contradiction:

Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

Each compartment is equipped with a compression bar that applies localized pressure to the necklace within that specific compartment. This local compression prevents the necklace from shifting or tangling with itself, while the overall case maintains an efficient volume by using a foam base that conforms to the jewelry shapes.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If necklaces hang freely in traditional cases, then viewing is improved, but the case must remain upright and portability is reduced

Engineering Contradiction:

ImproveviewingVSAvoidstorage orientation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The compartmentalized design with individual slots for each necklace allows the case to be stored in any orientation without the necklaces tangling or requiring gravity to maintain their position. The compression bars secure each piece independently, enabling vertical, horizontal, or tilted storage positions while maintaining jewelry organization.

Inventive Principle:

Principle #1Segmentation

4Stability of the object's composition

If compression is applied to secure jewelry, then tangling is prevented, but the case becomes less portable

Engineering Contradiction:

Improvejewelry securityVSAvoidcase weight

Core Design Contradiction:

Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The compression mechanism uses a flexible foam base that conforms to the shapes of the jewelry pieces, providing secure holding and compression without adding significant weight. The foam material provides the necessary compression force while keeping the overall case lightweight and portable.

Inventive Principle:

Principle #30Flexible shells and thin films
