Solution Overview

Problem

Existing online game systems face challenges in fully restraining real money trade, as players can exploit game balance by exchanging in-game items for real currency, leading to unfair advantages and potential loss of game balance.

Innovation Solution

A game system that includes a game content identification information storage unit, attribute information storage, and display control units to manage and display game content attributes in a way that hides variable information and player specifying details, making it difficult for players to determine the value and ownership of items, thereby discouraging real money trades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If all attribute information including variable information and player specifying information is displayed, then players can fully evaluate item value for fair trading, but players can identify specific players and items leading to real money trade exploitation

Engineering Contradiction:

Improveitem value evaluation accuracyVSAvoidreal money trade exploitation

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes harmful information elements (variable information and player specifying information) from the displayed attribute information. The display control unit is configured to display only constant information while excluding variable information that changes with game progression and player specifying information that identifies the player, thereby preventing real money trade exploitation while maintaining fair item evaluation

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments attribute information into three distinct categories: constant information (displayed), variable information (hidden), and player specifying information (hidden). This segmentation allows the system to selectively display only safe information elements that enable item evaluation without revealing information that could facilitate real money trade

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If constant information only is displayed, then real money trade is restrained, but players cannot fully assess item value and trading fairness

Engineering Contradiction:

Improvereal money trade restraintVSAvoiditem value assessment accuracy

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent introduces constant information as an intermediary that mediates between the need to restrain real money trade and the need to enable fair item evaluation. Constant information serves as a safe baseline that reveals essential item characteristics without exposing dynamic values or player identities, thus maintaining trading fairness while preventing exploitation

Inventive Principle:

Principle #24Intermediary (Mediator)
