Kinetic Motion Learning System for Pitching Habit Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In competitive games, batters struggle to utilize habit information of an opponent player's pitching motion, especially when this information cannot be expressed in words, limiting its relay and utilization across teams.
Innovation Solution
A kinetic motion learning system that includes a projector, pitching machine, and information storage unit to display and synchronize pitching motion videos and trajectory information, allowing batters to learn and recognize pitching habits through visual and auditory cues, even if the habits cannot be verbally described.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If habit information is expressed in words for relay to other batters, then information can be communicated verbally, but non-verbalizable habit information is lost
Solution Approach 1:
The patent uses video recording to create visual copies of the pitcher's actual motion. The video captures the habit information in its original form without requiring verbal translation, allowing exact replication and analysis of the pitcher's delivery mechanics, arm speed, release point, and other subtle cues that cannot be described in words.
Solution Approach 2:
The video serves as an intermediary medium between the pitcher's actual motion and the batter's understanding. Instead of direct verbal communication or direct observation, the video mediates by preserving and transmitting the habit information in a format that can be repeatedly viewed and analyzed, bridging the gap between the pitcher's unconscious habits and the batter's conscious understanding.
2Loss of information
If a batter watches pitching motion videos to learn habits, then visual information is provided, but synchronization with actual ball release timing is lost
Solution Approach 1:
The system uses frame-by-frame analysis and timing markers to provide feedback about the relationship between visual cues in the video and actual ball release timing. By marking specific frames corresponding to key moments in the pitching motion and synchronizing them with the video playback, the system enables the batter to learn the precise timing of habit cues relative to ball release.
Solution Approach 2:
The system performs preliminary analysis of the pitching motion video to identify and mark key frames before playback. By pre-synchronizing the video with timing information and marking critical moments in advance, the system prepares the learning material so that when the batter watches, the timing relationships are already established and visible, eliminating the need for real-time synchronization complexity during actual learning.
3Loss of information
If multiple pitch types are analyzed to identify habits, then comprehensive habit information is obtained, but analysis complexity increases
Solution Approach 1:
The patent segments the pitching motion into distinct phases (windup, arm cocking, acceleration, release, follow-through) and analyzes each phase separately for different pitch types. By breaking down the complex motion into manageable segments, the system can identify habit patterns in each phase without being overwhelmed by the overall complexity of multiple pitch types, allowing systematic comparison across different pitches.

AI summary
A kinetic motion learning device includes an information storage unit configured to associate and store in advance a pitching motion video and pitching trajectory information for a plurality of pitches actually delivered by a pitcher on a potential opponent team, and is configured to read a set of the pitching motion video and the pitching trajectory information stored in the information storage unit, output the pitching motion video being read to a projector, output the pitching trajectory information being read to a pitching machine, and control motion timings of the projector and the pitching machine so that a time of ball release of the pitcher in the pitching motion video displayed on a screen and a time of the pitching machine launching the ball with the pitching trajectory information match. The projector is configured to project the pitching motion video onto the screen so that the pitching motion video is displayed on the screen at a motion timing controlled by the kinetic motion learning device. The screen includes a hole through which a ball launched by the pitching machine can pass at a position of ball release of the pitcher in the pitching motion video displayed.
