Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hitting game machines face issues with coin input succession, target rotation speed control, weight reduction, and the need for a separate speed reducer, leading to manufacturing difficulties and game interference due to coin collisions and unwanted target movements.
Innovation Solution
A hitting game machine design featuring a rotating shaft with an eccentric shaft, a linear or tapered hit surface, and a hollow rotating shaft, along with a hitting member guide that reduces speed through friction and eliminates the need for a separate speed reducer, allowing successive coin input and precise target rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a separate speed reducer is used to reduce the speed of the coin, then the coin speed can be controlled, but the device complexity increases and manufacturing becomes difficult
Solution Approach 1:
The patent extracts and eliminates the separate speed reducer component from the system. Instead of using a dedicated speed reduction mechanism, the invention utilizes the natural friction between the coin guide surface and the coin itself to achieve speed reduction, thereby removing the complex mechanical components while maintaining the desired speed control function.
Solution Approach 2:
The patent replaces the mechanical speed reducer system with a friction-based speed reduction mechanism. The coin guide surface is designed with specific friction properties that naturally reduce coin speed without requiring complex mechanical gears, belts, or other moving parts, thus substituting a simple friction-based system for a complex mechanical one.
2Productivity
If the target rotates along with the circular plate, then the game can proceed, but successive coin input is blocked by coin collisions with the rotating target
Solution Approach 1:
The patent changes the rotational dimension of the target. Instead of the target rotating horizontally along with the circular plate (which blocks successive coin input), the target is designed to rotate vertically or in a different dimensional plane that does not interfere with the horizontal path of successive coins. This dimensional change allows coins to pass by without collision while the target still rotates for game functionality.
Solution Approach 2:
The patent implements preliminary positioning of the target before coin input. The target is positioned and oriented in advance to ensure that its rotation path does not intersect with the coin input trajectory. This preliminary arrangement prevents coin collisions before they can occur, enabling smooth successive coin input while maintaining target rotation capability.
3Stability of the object's composition
If the rotating shaft has sufficient width to prevent unwanted movement, then target stability improves, but the weight of the rotating shaft increases
Solution Approach 1:
The patent employs composite materials or material optimization for the rotating shaft. By using high-strength, low-density materials or composite structures, the rotating shaft can maintain sufficient structural integrity and stability to prevent unwanted target movement while keeping the weight minimized. This allows the shaft to be both stable and lightweight simultaneously.
Solution Approach 2:
The patent applies local quality enhancement to the rotating shaft. Instead of uniformly increasing the shaft width throughout, the design concentrates structural reinforcement only at critical locations where stability is needed to prevent unwanted target movement. This localized strengthening maintains target stability while minimizing overall weight by avoiding unnecessary material in non-critical areas.

Enables smooth and successive coin input, controlled target rotation speed, reduced weight, and improved game functionality by preventing unwanted target movements and collisions, enhancing user experience and manufacturing simplicity.
Implementation Method 1
a hitting member guide which allows the hitting member that has been inserted and is dropping to move towards the target, wherein a bottom surface of the hitting member guide along which the hitting member rolls is wavy or uneven so that a speed at which the hitting member moves downwards is reduced

AI summary
A hitting game machine allows the successive input of coins. In the hitting game machine, each target which is to be rotated by a hit of a hitting member includes an eccentric shaft. The target is configured such that a rotating shaft integrally rotates along with a hit surface which is to be hit by the hitting member. Further, a longitudinal section of the hit surface has a plate shape, a longitudinal section of which is in a linear shape or a shape that is reduced in width from an upper end thereof to a lower end. Therefore, it is possible for several hitting members to successively hit the same one of targets of a circular plate that is rotating.
