Lottery Content Duplication Prevention System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video game systems fail to prevent duplication of content awarded through lotteries, leading to player dissatisfaction when identical items are repeatedly given, and lack mechanisms to notify players when all available content has been distributed.
Innovation Solution
Implementing a system where a computer selects content by lottery and determines whether to award the selected content or an alternative based on duplication conditions, with notifications to players when all content has been given, preventing further lotteries and allowing alternative content selection from other players within the same group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is distributed through lottery in online games or social networking services, then player engagement and game attractiveness are improved, but player dissatisfaction occurs when identical content is repeatedly given
Solution Approach 1:
The system performs preliminary actions by determining in advance whether the lottery-won content satisfies a duplication condition before actually giving it to the player. This preliminary determination prevents player dissatisfaction by avoiding distribution of identical content while maintaining the lottery's adaptability in content selection.
2Productivity
If the system continuously offers lottery to players, then player engagement is maintained, but player discontent arises when all available content has been distributed
Solution Approach 1:
The system implements feedback mechanisms by notifying players when all content in the lottery pool has been distributed. This feedback loop maintains player engagement through continuous lottery offerings while ensuring reliability by informing players when no more content is available, preventing false expectations.
3Reliability
If the system manages content distribution to prevent duplication, then player satisfaction is improved, but system complexity increases
Solution Approach 1:
The system achieves self-service by enabling players to select alternative content from other players' inventories without requiring complex manual intervention. The automated determination of duplication conditions and the player-initiated alternative selection process simplify content management while maintaining reliability in content uniqueness.

AI summary
A given content list stores information about a content that has been given to a player. When a prize content selected by a lottery has been registered in the given content list, it is determined that the prize content satisfies a duplication condition, and an alternative content is selected from an alternative content list, and given to the player instead of the prize content selected by the lottery. An alternative content notification screen that notifies the player that the alternative content has been given to the player is displayed.
