Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soccer ball pitching devices lack stability and consistency in replicating ball flight over a significant number of pitches, making it difficult for players to receive repetitive quality kicks, especially for teams and skilled players, and are not portable enough for efficient training sessions.
Innovation Solution
A ball pitching apparatus with a main frame, rotatable tubular chute, and variable speed motors for the throwing wheels, along with caddy wheels and an adjustable rear leg for portability and trajectory control, providing a stable and consistent ball launch mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art soccer ball pitching devices are used, then ball pitching function is provided, but stability and consistency in replicating ball flight deteriorates over significant number of pitches
Solution Approach 1:
The device is divided into distinct functional modules: a main frame structure, a ball feeding mechanism with hopper, a pitching mechanism with adjustable wheels, and a control system. This segmentation allows each component to be optimized independently for reliability, with the main frame providing stable support for the pitching mechanism throughout extended operation
Solution Approach 2:
The ball feeding mechanism is nested within the main frame structure, with the hopper positioned to gravity-feed balls into the pitching mechanism. This nested arrangement ensures continuous ball supply without external intervention, maintaining operational consistency over extended pitching sessions
2Ease of operation
If soccer ball pitching devices are made portable for easy movement, then ease of operation improves, but stability and structural rigidity deteriorates
Solution Approach 1:
The device incorporates adjustable components including height-adjustable legs and angle-adjustable pitching mechanism that can be locked into position. This dynamic adjustability allows the structure to be optimized for stability during operation while maintaining portability through controlled rigidity rather than fixed rigidity
Solution Approach 2:
Different parts of the structure have different rigidity characteristics - the main frame and base provide rigid support for stable ball pitching, while the adjustable legs and mounting mechanisms provide flexibility for portability and setup adaptation. This localized variation in structural quality resolves the contradiction between stability and portability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus ensures reliable and consistent ball flight with adjustable spin and trajectory, enabling rapid repetition for individual and team drills, and is portable for easy storage and transportation, meeting the demands of both novice and professional players.
Implementation Method 1
two spinning opposing wheels that engage the ball as it passes through the wheels and impart speed and spiral spin to the ball
Implementation Method 2
rear leg having an adjustable extension to vary the height and angle of the chute to adjust the trajectory of the ball

AI summary
A system and method for pitching balls, particularly round balls such as soccer balls. The system and method are flexibly designed to simulate different types of pitches including but not limited to kicks, throws, and headers. A main frame has a frame with a front panel, a rear panel and a top panel. A tubular chute is rotatably mounted in the interior portion of the main frame with a set of bearings. A pair of opposing ball throwing wheels are fitted to the rotatable tubular chute for launching the ball from the chute. Each wheel is driven by a variable speed motor that is controlled by a variable switch mounted to the main frame. A pair of caddy wheels is attached to the main frame for portability of the apparatus, along with a rear support having an adjustable extension to vary the height and angle of the rotatable tubular chute to adjust the trajectory of the ball. A ball feed chute is mounted to the main frame onto which balls are loaded to be pitched.
