Solution Overview

Problem

Electronic trading card games (TCGs) that enable online competition among users lack the entertainment value provided by physical card games, as the visual representation of cards and gameplay mechanics may be less engaging.

Innovation Solution

A non-transitory computer readable medium storing a program that controls a display to differentiate game elements of different types visually, such as leader and member cards, and employs three-dimensional models for leader cards, along with distinct display effects to enhance gameplay interaction and strategy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If two-dimensional images of cards are placed on a field in an electronic TCG, then the game can be played online with simplified graphics, but the entertainment value and visual engagement are reduced

Engineering Contradiction:
Improveease of implementationVSAvoidentertainment value
Core Design Contradiction:
Ease of manufactureVSExtent of automation

Solution Approach 1:

The patent applies dimensionality change by transitioning from two-dimensional card images to three-dimensional models for leader cards. This allows the game to maintain online playability while significantly enhancing visual engagement and entertainment value through spatial depth and perspective effects.

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

Solution Approach 2:

The patent applies local quality by differentiating the visual representation of different card types. Leader cards are displayed as three-dimensional models with distinct visual properties, while member cards remain as two-dimensional images. This creates localized visual variety that enhances player engagement without requiring complete 3D rendering of all elements.

Inventive Principle:
Principle #3Local quality

2Device complexity

If all game elements are displayed using the same visual form, then the display system remains simple, but player interaction and strategy depth are reduced

Engineering Contradiction:
Improvedisplay complexityVSAvoidplayer interaction
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent applies local quality by assigning different visual forms to different game elements based on their roles. Leader cards use three-dimensional models to convey importance and strategic weight, while member cards use traditional two-dimensional images. This differentiation enhances player interaction and strategy depth by visually communicating the hierarchical relationships between different card types.

Inventive Principle:
Principle #3Local quality

AI summary

A non-transitory computer readable medium stores a program causing a computer to execute a display control process for controlling a display device to display a game screen containing a field, the computer executing an electronic game that progresses by placing game elements on the field. The display control process includes placing and displaying, among game elements associated with a player, a game element of a first type and a game element of a second type in visually different forms on the field, the game element of the first type and the game element of the second type having different roles in progression of the electronic game.
