Solution Overview

Problem

There is a lack of devices that assist batters in perfecting their swing mechanics, particularly in maintaining balance, preventing bat casting, swinging around the ball, and rolling of the hands during a swing, and accommodating athletes of all sizes.

Innovation Solution

A baseball swing training device with an elongate member and protrusions that fit about the batter's elbows, providing balance and guiding a proper hand path, while being extendable to accommodate different sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-length training device is used, then it can provide stable structural support, but it cannot accommodate athletes of various sizes

Engineering Contradiction:

Improveaccommodation of various athlete sizesVSAvoidextendable structure with segments and apertures

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The elongate member is divided into multiple segments that can be extended or retracted to accommodate different athlete sizes. The segments are connected in a telescopic arrangement, allowing the device to adjust its length while maintaining structural integrity during the swing motion.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The telescopic segments are nested within each other, with inner segments sliding within outer segments. This nested structure allows compact storage when retracted and extended configuration when needed, providing adaptability without excessive complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If protrusions are placed about the inside elbows, then balance and hand path can be guided, but the device may interfere with natural swing motion

Engineering Contradiction:

Improveguidance of proper swing mechanicsVSAvoidinterference with natural swing motion

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The protrusions serve as intermediary contact points between the training device and the batter's elbows. They provide tactile feedback and physical guidance without completely restricting the natural swing motion, acting as a mediator that guides mechanics while allowing freedom of movement.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protrusions are positioned at specific locations (inside elbows) where they can provide localized guidance for elbow positioning and hand path without affecting other parts of the swing. This localized intervention minimizes overall interference with natural swing mechanics.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the elongate member is made rigid for stability, then it can provide consistent positioning, but it cannot be adjusted for different athlete sizes

Engineering Contradiction:

Improvepositioning stability during swingVSAvoidadjustability for different athlete sizes

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The elongate member transitions from a static fixed-length structure to a dynamic telescopic structure that can adjust its length. The segments can be extended or retracted to match different athlete sizes, and once positioned, they provide stable support during the swing motion.

Inventive Principle:

Principle #15Dynamics

AI summary

The present invention is directed to a baseball swing training device that helps batters perfect their swing mechanics when hitting a baseball or a softball. The baseball swing training device may include an elongate member and a plurality of protrusions extending from the elongate member. The elongate member may be length-adjustable, such as by including a locking mechanism which may engage with a plurality of apertures, such that the extendable device may accommodate users of various wingspans. The device assists in providing balance to a batter by getting their top hand elbow into the slot, while keeping their bottom hand elbow soft.
