Softball Pitching Training Device with Unidirectional Pivot Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing softball training devices are not ideal for softball pitching due to differences in mechanics compared to baseball pitching, and they are often expensive and not readily available for pitchers to use effectively.
Innovation Solution
A portable, inexpensive softball training device with a pivotally mounted plate assembly that allows for forward pivoting but not rearward pivoting, providing feedback through an auditory signal when proper rear leg drive is executed, allowing pitchers to maximize rear leg drive and transfer weight effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional baseball training devices are used for softball pitching, then rear leg drive training is provided, but the device does not account for differences in softball pitching mechanics (foot positioning at right angle vs. parallel in baseball)
Solution Approach 1:
The balance plate is designed with an asymmetric directional constraint system that allows pivoting only in the forward direction (toward home plate) while preventing rearward pivoting. This asymmetric movement capability matches the specific mechanics of softball pitching where the dominant foot moves forward perpendicular to the pitching rubber, unlike baseball where the foot moves parallel to the rubber. The unidirectional pivot constraint provides softball-specific training without requiring a completely redesigned device.
2Measurement precision
If professional instruction and video equipment are used to monitor rear power drive, then pitching mechanics can be monitored, but the equipment is expensive and not readily available
Solution Approach 1:
The balance plate assembly serves as a self-monitoring device that automatically provides feedback to the pitcher about their rear power drive execution. When the pitcher properly drives the dominant foot forward with sufficient force, the balance plate pivots forward and contacts the strike plate, generating an audible click sound. This self-feedback mechanism eliminates the need for expensive external monitoring equipment like video analysis systems or professional instructors, making precise monitoring accessible to individual pitchers.
3Ease of operation
If a pivotally mounted plate assembly is used to provide training feedback, then rear leg drive can be trained, but the device must be simple and portable
Solution Approach 1:
The training device is segmented into distinct functional components: a balance plate assembly that pivots on a fulcrum, a strike plate positioned forward of the fulcrum, and an audible feedback mechanism. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity. The balance plate can be separately mounted and adjusted, and the entire device can be disassembled for portability, making it easy to operate and transport while providing effective training feedback.

AI summary
A softball training device includes a plate assembly pivotally connected to a support member. The plate assembly includes a flat, circular balance plate and a downwardly protruding kick stand formed on its rear end. The support member includes an enlarged base and rectangular mounting bracket transversely disposed on the base, the balance plate directly teetering on the mounting bracket. In use, the training device can be used to train a hitter to maximize lower power drive. Specifically, the hitter centers her rear foot on the balance plate and positions her other foot in front of the device. The hitter then loads her weight rearward, the kick stand keeping the balance plate horizontal. The hitter finally transfers her weight forward through accelerated hip and torso rotation so that the balance plate pivots forward and strikes the base to create an audible signal. With hips and torso initiating the forward movement, the arms are similarly pulled forward so the bat travels through the hitting zone.
