Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ball pitching training devices do not effectively improve muscle strength and throwing technique in softball or baseball players.
Innovation Solution
A ball pitching training device comprising a flexible fiberglass rod with a resistance band and adjustable apertures, a foam support cushion, and a body strap, which provides resistance to simulate throwing movements and promote proper form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a resistance band is attached to the throwing ball, then muscle strength is improved through resistance training, but the device becomes more complex
Solution Approach 1:
The resistance band serves multiple functions: providing resistance during throwing motion, storing elastic energy, and enabling adjustable intensity through different attachment points. This multi-functionality justifies the added complexity by delivering comprehensive training benefits in a single integrated component.
Solution Approach 2:
The resistance band provides dynamic resistance that varies throughout the throwing motion, increasing resistance as the band stretches and decreasing as it recoils. This dynamic characteristic mimics actual throwing mechanics more closely than static resistance, improving training effectiveness despite added device complexity.
2Adaptability or versatility
If adjustable apertures are provided on the connection head, then resistance can be adjusted to suit different training levels, but the device structure becomes more complex
Solution Approach 1:
The connection head is segmented with multiple discrete apertures arranged in a pattern, allowing the attachment clip to engage at different positions. This segmentation provides graduated resistance levels without requiring a complex continuous adjustment mechanism, balancing adaptability with structural simplicity.
Solution Approach 2:
The user can independently adjust the resistance level by moving the attachment clip between apertures without requiring tools or complex procedures. This self-service adjustment capability enhances adaptability while keeping the device structure relatively simple through intuitive user interaction.
3Ease of operation
If a foam support cushion is added to the inner rod, then user comfort is improved, but the device becomes more complex
Solution Approach 1:
The foam cushion is applied locally at the specific contact point on the inner rod where the user's body touches the device. This targeted cushioning improves comfort only where needed, rather than requiring foam coverage throughout the entire device, thus minimizing the increase in device complexity.
4Reliability
If a body strap with adjustment clip is provided, then the device can be securely worn by different users, but the device structure becomes more complex
Solution Approach 1:
The body strap incorporates an adjustment clip that allows the strap length to be dynamically modified to fit different user sizes and preferences. This dynamic adjustability ensures a secure and comfortable fit for various users while maintaining relatively simple construction through a straightforward clipping mechanism.

AI summary
A ball pitching training device including a flexible inner rod with a handle disposed on a bottom end and an adjustable connection head protruding from a top end. Adjustment apertures are vertically aligned on the connection head. A support cushion encircles a portion of the inner rod. A body strap is disposed on the inner rod by a pair of rings. An adjustment clip is disposed on the body strap and adjusts a length of the body strap. An attachable ball comprises a resistance band, a circular attachment clip, and a baseball. The attachment clip attaches the resistance band and baseball to the connection head by engaging one of the adjustment apertures. A user wears the body strap, securing the device, grasps the baseball and simulates a throwing movement. The resistance band and flexible inner rod provide resistance against the movement and promote muscle growth and proper throwing form.
