Solution Overview

Problem

Existing card boxes lack separate spaces for special cards or game props, making it difficult to locate and store them during gameplay, and they are prone to being lost when removed from the main container.

Innovation Solution

A magnetic type card box assembly with adherence boxes magnetically attached to the side surfaces of the main body, specifically designed to hold special cards and game props, utilizing magnets and iron sheets for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single unified box structure is used for all cards, then the structure is simple and compact, but there is no separate space for special cards or game props making them difficult to locate and store

Engineering Contradiction:
ImproveEase of locating and storing special cards and game propsVSAvoidStructure complexity of the card box
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The card box is divided into multiple independent compartments: a main body for common cards and separate adherence boxes for special cards and game props. This segmentation allows different types of items to be stored in dedicated spaces, improving ease of operation while maintaining overall structural simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adherence boxes are attached to the outer surface of the card box main body, utilizing the external surface area as an additional storage dimension. This allows special cards and game props to be stored in a separate spatial plane without increasing the internal volume complexity of the main body.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If special cards or game props are removed from the main container for storage, then they can be stored separately, but they are prone to being lost

Engineering Contradiction:
ImproveEase of storing special cards and game propsVSAvoidRisk of losing special cards or game props
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adherence boxes are magnetically attached to the card box main body, merging the storage of special cards and game props with the main container. This ensures that when the main box is carried or stored, the adherence boxes remain attached, eliminating the risk of loss while maintaining easy access for storage and retrieval.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The magnetic attachment mechanism replaces traditional mechanical fastening methods. The magnets embedded in the card box main body automatically hold the adherence boxes in place through magnetic attraction, providing reliable retention without complex mechanical structures.

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

3Ease of operation

If multiple separate containers are used for different card types, then separate storage space is provided, but the device becomes more complex and harder to carry

Engineering Contradiction:
ImproveSeparate storage space for different card typesVSAvoidNumber of separate containers
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The card box main body serves multiple functions: it stores common cards in its interior cavity and simultaneously provides magnetic attachment surfaces for adherence boxes containing special cards and game props. This multi-functionality consolidates multiple storage needs into a single unified structure, reducing the number of separate containers needed.

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

Solution Approach 2:

The adherence boxes are nested on the external surface of the card box main body, similar to nested dolls. This allows the adherence boxes to be integrated with the main structure without adding significant external dimensions, maintaining compactness while providing separate storage spaces.

Inventive Principle:
Principle #7Nested doll (Nesting)
