Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the special event application timing is controlled based on the number of games, then the frequency of special events can be secured, but special events may not be applied during special games even when conditions are met, reducing player satisfaction

Engineering Contradiction:
Improvefrequency of special event applicationVSAvoidplayer satisfaction
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The controller determines in advance whether to apply a special event during special games by lottery drawing before the special games start. This preliminary determination ensures that special events are guaranteed to be applied at least once during the special games, preventing player dissatisfaction while maintaining controlled frequency through the lottery mechanism.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If special events are applied frequently during normal games, then player engagement is maintained, but the opportunity cost reduces special event applications during special games

Engineering Contradiction:
Improveplayer engagementVSAvoidspecial event application in special games
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The controller performs lottery drawing before special games start to determine if a special event will be applied during the special games. This preliminary action reserves the opportunity for special events in special games, ensuring that at least one special event is guaranteed during the special games regardless of how many special events were applied during normal games.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If the gaming machine follows strict game condition rules for special event application, then game fairness is maintained, but special events are not applied during special games even when trigger conditions are satisfied

Engineering Contradiction:
Improvegame rule consistencyVSAvoidplayer satisfaction
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The controller determines in advance by lottery drawing whether to apply a special event during special games, before the special games actually start. This approach maintains game rule consistency by using a predetermined mechanism rather than ad-hoc decisions, while simultaneously ensuring player satisfaction by guaranteeing at least one special event during the special games.

Inventive Principle:
Principle #10Preliminary action

AI summary

A gaming machine providing a player with a game includes: a display unit configured to display the game; and a controller configured to determine contents of the game to be displayed on the display unit. The controller executes a predetermined number of special games when a first condition is satisfied during execution of a normal game, and applies a special event when a second condition is satisfied during execution of the normal game or execution of the special games. The controller applies the special event at least once in the predetermined number of the special games regardless of the second condition.
