Baseball Game Board Selection Unit for Gradational Pitch Height Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baseball game boards are difficult for beginners to use effectively, as they require balanced adjustments to control the trajectory of the ball, making it challenging to pitch the ball to intended heights and enjoy various pitching functions.
Innovation Solution
A baseball game board with a selection unit that allows gradational selection of ball height, adjusting the trajectory of the ball shot from the pitching unit, using a plate-shaped member and pitching operation lever configuration that simplifies the operation by maximizing the movement amount of the pitching operation lever.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operator pulls the pitching operation lever to adjust the ball trajectory, then the ball can be pitched to different heights, but the operator requires balanced adjustment of the pulling distance which is difficult for beginners to master
Solution Approach 1:
The invention divides the continuous lever pulling operation into discrete segmented positions using a plate-shaped member with multiple through-holes. Each hole corresponds to a specific pulling distance, creating distinct pitch height options (e.g., high, medium, low). This segmentation transforms the complex continuous adjustment into simple discrete selection, making it easy for beginners to use while maintaining versatile pitching functions.
Solution Approach 2:
The plate-shaped member is positioned in advance to block the lever's movement path, preliminarily determining the maximum pulling distance. By pre-positioning the plate at different locations, the system prepares multiple fixed leverage points before the operator pulls the lever. This preliminary action eliminates the need for operators to judge the correct pulling distance, simplifying the operation while preserving various pitch height options.
2Adaptability or versatility
If the pitching operation lever is designed to allow full movement for trajectory adjustment, then various pitch heights can be achieved, but the operation becomes complex and difficult for beginners
Solution Approach 1:
The plate-shaped member acts as an intermediary between the operator and the pitching operation lever. It mediates the lever's movement by physically blocking it at predetermined positions, transforming the operator's simple pulling action into controlled discrete movements. This intermediary component simplifies the interface while maintaining the ability to achieve various pitch heights, reducing operational complexity without sacrificing versatility.
Solution Approach 2:
The invention changes the parameter of lever movement distance from continuous to discrete by introducing the plate-shaped member with fixed holes. Instead of allowing the lever to move freely along a continuous range, the plate constrains it to specific distances corresponding to different pitch heights. This parameter transformation simplifies the operation for beginners while preserving multiple pitch options.

AI summary
A baseball game board includes: a main body unit simulating a baseball stadium and including an upper surface plate; a pitching unit configured to pitch a ball to allow the ball to move while floating in air; a batting unit configured to hit the ball; and a selection unit configured to gradationally select a ball height of the ball at a time of passing through the batting unit. In accordance with a selection result of the selection unit, a trajectory of the ball shot from the pitching unit is changed.
