Screen Baseball System Pitching Machine Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen golf systems are inadequate for baseball as they lack the dynamic interaction and spatial requirements needed for a realistic baseball experience, particularly in determining 'strike' or 'ball' and calculating scores, due to the need for multiple players and a virtual ballpark.
Innovation Solution
A screen baseball system that allows users to select pitch types, adjust game conditions, and track batting actions using a pitching machine, detection units, and online communication to simulate a virtual baseball field, enabling real-time sharing of game information and storing batting images for training and character development.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a screen golf system is applied to baseball, then spatial utilization is improved, but game realism and dynamic interaction deteriorate
Solution Approach 1:
The system divides the baseball game into separate functional modules: a pitching machine section for ball delivery, a batting section for user action, a detection section for tracking ball trajectory, and a display section for visual feedback. This segmentation allows each component to be optimized independently while maintaining overall game realism.
Solution Approach 2:
The patent introduces a screen as an intermediary between the physical batting action and the virtual baseball field. The projection apparatus displays a virtual ballpark on the screen, creating an immersive environment that maintains game realism while utilizing limited indoor space efficiently.
2Extent of automation
If conventional pitching machines are used in batting cages, then automated pitching is improved, but user control over pitch selection deteriorates
Solution Approach 1:
The system dynamically switches between automated pitching mode (for practice) and manual pitch selection mode (for gameplay). The pitch type selection means allows users to choose from multiple pitch types (fastball, curveball, slider, etc.), and the system adapts by adjusting the pitching machine's parameters accordingly, maintaining both automation and user control.
Solution Approach 2:
The pitching machine is designed to perform multiple functions: it can automatically deliver balls at various speeds and trajectories for practice, and it can also respond to user-selected pitch types for gameplay. The system universally handles different pitch types through a unified control interface.
3Reliability
If baseball is played with multiple players and large space requirements, then game authenticity is improved, but accessibility and convenience deteriorate
Solution Approach 1:
The system creates a virtual copy of a baseball field and game environment through the projection apparatus and screen. This virtual ballpark replicates the authentic baseball experience including the diamond, outfield, and scoring systems, allowing single users to play alone while maintaining game authenticity.
Solution Approach 2:
The system enables self-service gameplay where a single user can complete the entire baseball experience independently. The user selects pitch types, bats the ball, and receives automated feedback through the detection and display systems, eliminating the need for multiple players or assistants.
4Device complexity
If screen golf systems use fixed ball positions, then system simplicity is improved, but baseball game dynamics deteriorate
Solution Approach 1:
The system dynamically adjusts ball delivery parameters based on selected pitch types. The pitching machine can vary ball speed, rotation, and trajectory to simulate different pitch types (fastball, curveball, slider, changeup), maintaining baseball game dynamics while using a relatively simple mechanical platform.
Solution Approach 2:
The system changes physical parameters of ball delivery (velocity, spin rate, release point) according to the selected pitch type. This allows the same pitching machine to produce diverse ball trajectories and behaviors, matching the versatility of real baseball pitching without requiring multiple physical devices.
