Solution Overview

Problem

Existing game boards struggle with allowing appropriate operations at appropriate times when sudden situation changes occur, particularly in soccer game boards where players must switch between operating outfield player and goalkeeper figures quickly.

Innovation Solution

A game board design featuring operation levers with movable components that allow simultaneous movement and rotation of outfield player and goalkeeper figures, enabling them to move in different directions in response to lever operations, even during sudden situation changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple operation levers are provided for different player figures, then each player figure can be controlled independently, but the user cannot respond quickly when situation changes occur

Engineering Contradiction:
ImproveResponse time to situation changesVSAvoidNumber of operation levers
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The single operation lever is designed to control multiple player figures (outfield player and goalkeeper) through different operational modes. By pushing the lever in different directions or positions, the user can switch between controlling the outfield player and the goalkeeper, eliminating the need for separate levers while maintaining full control capability

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the control functions of multiple operation levers into a single unified lever. The operation lever integrates both outfield player control and goalkeeper control functions, allowing the user to switch between figures by changing the lever's position or direction of operation, thereby reducing device complexity while improving response time

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If the user must switch between outfield player and goalkeeper levers, then each figure can be controlled precisely, but the operation becomes slow and inappropriate for sudden changes

Engineering Contradiction:
ImproveSpeed of player figure controlVSAvoidOperational versatility
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The single operation lever serves multiple functions by controlling both the outfield player and goalkeeper figures. The lever can be operated in different positions or directions to switch between figures, providing full operational versatility while enabling rapid switching without the delay of moving between separate levers

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The operation lever is designed with dynamic control capabilities where the same lever can dynamically switch between controlling different player figures based on its position or direction of operation. This dynamic functionality allows rapid adaptation to situation changes while maintaining precise control over both outfield player and goalkeeper

Inventive Principle:
Principle #15Dynamics

AI summary

A game board (1) includes: a field plate (3); an operation lever (5) disposed below the field plate (3); a first player figure (6) disposed above the field plate (3) and attached on an upper side of the operation lever (5); and a second player figure (7) disposed above the field plate (3) and attached at a position different from the upper side of the operation lever (5). The first player figure (6) and the second player figure (7) are configured to move in accordance with an operation on the operation lever (5) to which the first player figure (6) is attached.
