Solution Overview

Problem

Existing cards, such as greeting and holiday cards, typically consist of a single unit with limited space for additional content, lacking a compact and efficient system for multiple cards to be arranged in an enclosed relationship.

Innovation Solution

A card system comprising a series of cards with varying sizes, where each card has a pocket to receive the next smaller card, forming enclosed assemblies that can be compactly arranged and potentially housed within an envelope, with each card featuring foldable panels and pop-up displays for enhanced decoration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple cards are included in the system, then the quantity of content is improved, but the volume and complexity of the system increase

Engineering Contradiction:

Improvequantity of cardsVSAvoidsystem volume

Core Design Contradiction:

Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The patent implements a nested card structure where smaller cards are placed inside larger cards. Each card contains a pocket that receives the next smaller card in the sequence, creating a nested arrangement similar to Matryoshka dolls. This allows multiple cards to be contained within a compact volume, resolving the contradiction between increasing card quantity and maintaining system volume.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Quantity of substance

If multiple cards are included in the system, then the quantity of content is improved, but the device complexity increases

Engineering Contradiction:

Improvequantity of cardsVSAvoidsystem complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The nested structure provides a systematic organizational method where each card has a designated pocket for the next card. This regular repeating pattern simplifies the overall system architecture despite containing multiple cards, making the complexity manageable through consistent structural repetition.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The system divides the multi-card content into discrete, separable card units that can be individually accessed. Each card is a self-contained segment with its own pocket structure, allowing the system to manage complexity by breaking down the whole into manageable, standardized segments.

Inventive Principle:

Principle #1Segmentation

3Volume of stationary object

If cards are arranged in an enclosed relationship, then the compactness is improved, but the ease of operation decreases

Engineering Contradiction:

ImprovecompactnessVSAvoidease of card access

Core Design Contradiction:

Volume of stationary objectVSEase of operation

Solution Approach 1:

The nested arrangement with accessible pockets allows cards to remain compact when closed while enabling easy sequential access when opened. The pocket structure is designed to receive and hold cards securely yet allow for straightforward insertion and removal, balancing compactness with operational ease.

Inventive Principle:

Principle #7Nested doll (Nesting)
