Solution Overview

Problem

Conventional protective cases for trading cards lack adequate protection and ease of handling, often allowing for easy damage and not providing optimal visibility.

Innovation Solution

A protective case with a front cover and back cover that are removably coupled using magnets, allowing for secure retention and display of collectibles, with optional transparency and decorative features, and the ability to interlock multiple cases for a stand-alone display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional protective cases use simple plastic pouches with openings for easy handling, then ease of operation is improved, but protection reliability deteriorates

Engineering Contradiction:

Improveease of handlingVSAvoidprotection reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The protective case is divided into separate front and back covers that can be independently handled and assembled, allowing easy insertion and removal of cards while maintaining secure protection when closed

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The front and back covers are combined with a securing mechanism (magnets, clips, or latches) to create a unified protective structure that provides both ease of operation and reliable protection

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If conventional protective cases use secure closures to protect cards, then protection reliability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveprotection reliabilityVSAvoidease of handling

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Traditional mechanical fasteners (screws, clips, latches) are replaced with magnetic attraction forces, allowing the covers to be easily attached and detached through simple proximity movements while maintaining secure closure

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If protective cases use opaque materials to protect cards, then protection reliability is improved, but visibility deteriorates

Engineering Contradiction:

Improveprotection reliabilityVSAvoidvisibility

Core Design Contradiction:

ReliabilityVSIllumination intensity

Solution Approach 1:

The case structure applies different material properties to different regions: transparent or translucent materials are used for the covers to maintain visibility, while the internal recess and sealing elements provide the necessary protection, creating localized functional zones

Inventive Principle:

Principle #3Local quality

4Ease of operation

If protective cases are designed as individual units for portability, then ease of operation is improved, but device complexity deteriorates when creating displays

Engineering Contradiction:

ImproveportabilityVSAvoiddisplay configuration complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The protective case is designed with dual functionality: it serves as an individual protective unit for portability, and simultaneously functions as a modular component in larger display configurations through the inclusion of intercase securing mechanisms

Inventive Principle:

Principle #6Universality (Multi-functionality)

5Ease of operation

If protective cases allow easy removal of covers for handling, then ease of operation is improved, but protection reliability deteriorates

Engineering Contradiction:

Improveease of handlingVSAvoidprotection reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Traditional mechanical fasteners requiring manual manipulation are replaced with magnetic attraction, allowing covers to be easily removed and reattached through simple proximity movements while maintaining secure closure when assembled

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A protective case display is provided. The protective case display may comprise a plurality of protective cases. Each protective case, of the plurality of protective cases, may comprise a front cover (102) and a back cover (104) removably coupled to the front cover. The front cover and the back cover, when coupled, may form a recess configured to receive an object for insertion therein. Each protective case, of the plurality of protective cases, may further comprise a securing mechanism (108,110), coupled to the front cover and the back cover, configured to removably couple the front cover to the back cover. The securing mechanism may be configured to secure one or more protective cases to one or more other protective cases, preventing movement between the plurality of protective cases, enabling the plurality of protective cases to form a stand-alone display comprising the plurality of protective cases.
