Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a game uses only chance mechanisms like automatic ball delivery and fixed paths, then operation simplicity is improved, but player engagement and skill involvement deteriorate

Engineering Contradiction:
Improveoperation simplicityVSAvoidplayer engagement
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The platforms are made dynamically adjustable during gameplay through lever mechanisms. Players can tilt each platform independently to any angle, creating dynamic changes in ball trajectories. This transforms a static chance-based game into a dynamic skill-based experience while maintaining operational simplicity through intuitive lever controls.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The game board is segmented into multiple independent platforms (at least three levels) that can be controlled separately. Each platform acts as an independent control zone, allowing players to manipulate ball paths segment by segment. This segmentation enables complex skill-based gameplay while keeping each individual control action simple.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a game provides fixed paths and obstacles, then device complexity is reduced, but gameplay variety and adaptability deteriorate

Engineering Contradiction:
Improvestructure simplicityVSAvoidgameplay variety
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

Instead of fixed paths, the invention uses dynamically adjustable platforms that can be tilted to different angles. The ball paths are not predetermined but emerge from the interaction between gravity and the adjustable platform angles. This maintains relatively simple device structure while enabling infinite gameplay variety through combinatorial platform configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the angle parameter of each platform dynamically during gameplay. By adjusting the tilt angle of platforms through levers, the game creates varied ball trajectories without changing the physical structure or adding complex pathing mechanisms. This parameter-based approach maintains structural simplicity while achieving gameplay diversity.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple platforms are made adjustable via levers and connecting rods, then player skill involvement is improved, but device complexity increases

Engineering Contradiction:
Improveskill involvementVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple platforms are connected through a shared lever mechanism system. The levers are mechanically coupled to multiple platforms via connecting rods, allowing a single lever action to influence multiple platforms simultaneously or in sequence. This merging of control functions reduces the number of independent controls needed while maintaining complex platform manipulation capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Connecting rods act as intermediary mechanical elements between the levers and platforms. These intermediaries translate lever movements into platform tilts, providing mechanical advantage and smooth motion control. The intermediary mechanism simplifies the direct connection between player input and platform response while enabling precise angular adjustments.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Measurement precision

If the game requires precise ball placement detection, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improveball placement detectionVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The game system automatically detects ball placement and triggers prize delivery without requiring external intervention or complex verification mechanisms. Sensors positioned at strategic locations detect when balls reach designated areas, and the system self-manages the prize dispensing process. This self-service approach achieves precise detection while minimizing additional system complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The sensor system provides immediate feedback about ball placement to the prize delivery mechanism. When sensors detect specific ball configurations or positions, they trigger corresponding prize dispensing actions. This feedback loop enables precise measurement and automatic response, creating an engaging player experience without requiring complex manual verification systems.

Inventive Principle:
Principle #23Feedback

AI summary

An arcade game having a housing that forms an interior compartment containing three lower and three upper platforms and a perforated platform. The three lower platforms are underneath the perforated platform, tilted toward downwardly, and parallel to each other. The perforated platform is horizontal with a plurality of apertures configured to allow a ball to pass through them. Two levers at the front of the housing are pivotally connected to a bracket and mechanically coupled to one of the upper platforms via a cable and pulley. A central connecting rod extends through the center of the three upper platforms with a ball bearing at each point at which the rod passes through the platform. Two rear connecting rods connect the rear corners of the three upper platforms to each other with a ball bearing at each point at which the rear connecting rods extend through the platforms.
