Solution Overview

Problem

Existing game systems fail to maintain the rarity and value of game content once it is provided to players, as content becomes accessible to all players regardless of its initial value or rarity.

Innovation Solution

Implementing a system where game content is assigned varying validity periods, allowing players to obtain and use content for a limited time, with the option to extend or obtain new validity periods through gacha requests, and restricting use if the period lapses, ensuring content remains valuable and rare.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If game content is provided to players without time limits, then players can use the content indefinitely, but the rarity and value of the game content cannot be maintained

Engineering Contradiction:
Improveusage duration of game contentVSAvoidrarity and value of game content
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The patent implements periodic action by assigning validity periods to game content that expire after a predetermined time. This forces content to be periodically refreshed or re-obtained, maintaining its perceived value and rarity. The system automatically manages these time-based cycles without player intervention, ensuring content rotates in and out of availability.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent applies dynamics by making the availability status of game content changeable over time. Content transitions from an available state to an expired state, and can be revived through new acquisition. This dynamic lifecycle management prevents static perpetuity that would devalue content, while allowing flexible control over when and how content becomes available again.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If new game content is continuously introduced, then player engagement is maintained, but existing content loses its exclusivity and value

Engineering Contradiction:
Improvegame content varietyVSAvoidexclusivity of game content
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments game content into distinct validity period intervals, creating separate temporal zones for different content. This allows multiple content types to coexist with differentiated availability windows, maintaining exclusivity within each segment while providing overall variety. Players must choose which segmented content to pursue based on their timing and strategic needs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by assigning different validity period characteristics to different game content items. Rather than uniform time limits, each content type can have customized duration and renewal rules, creating localized value propositions. This allows simultaneous introduction of new content with varying exclusivity profiles without uniformly devaluing existing content.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If game content can be obtained through lottery with fixed probabilities, then simplicity is maintained, but player motivation decreases over time as content becomes common

Engineering Contradiction:
Improvecontent acquisition simplicityVSAvoidcontent value perception
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements feedback by making provision probabilities dynamic rather than fixed. The system monitors acquisition frequencies and adjusts probabilities accordingly, providing feedback loops that maintain content value. When content becomes too common, probabilities are adjusted to reduce further acquisitions, preserving scarcity and player motivation while keeping the lottery mechanism simple to operate.

Inventive Principle:
Principle #23Feedback

AI summary

An information processing device that progresses a game using a game content associated with a player. In response to receiving an obtaining request, the device selects a subset of game contents, where a portion of the game contents has a same identification information and each of the portion of the game contents has a different validity period. The device obtains a validity period associated with each of the selected game contents. When a first game content associated with the player has the same identification information as a second game content, the device updates, for each game content, a validity period of the first game content based on the validity period of the second game content in the subset of game contents. The device then restricts use of the first game content in the game when the validity period of the first game content lapses.
