Portable Baseball Tee with Mechanical Autoloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing batting tees require manual loading and unloading of balls, are prone to ball spillage when struck, and are often bulky and power-dependent, making them inefficient for practice and transport.
Innovation Solution
A compact, lightweight batting tee system with an expandable constraint mechanism that automatically loads and unloads balls, allowing for sequential ball positioning without manual handling and maintaining ball containment upon impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a ball reservoir is added to the batting tee, then ball loading is automated, but the tee becomes vulnerable to ball spillage when struck by the bat
Solution Approach 1:
The ball reservoir is divided into multiple compartments separated by partitions. This segmentation prevents balls from spilling when one compartment is struck, as the partitions contain the balls within their respective sections while still allowing the loading mechanism to function.
2Reliability
If the batting tee is made large and heavy to absorb bat strikes, then ball containment is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The tee is divided into modular components including a collapsible stand with telescoping legs and a separable ball reservoir. This segmentation allows the tee to be disassembled for easy transport while maintaining stability during use through the expanded leg structure.
Solution Approach 2:
The stand legs are designed to be collapsible and extendable, allowing the tee to transition between a compact transport state and a stable operational state. The dynamic structure provides stability when deployed without adding permanent weight.
3Extent of automation
If motorized mechanisms are used for ball loading, then automation is improved, but device complexity and power requirements increase
Solution Approach 1:
The ball loading mechanism uses the kinetic energy from the bat strike itself to load the next ball. When the bat hits the ball on the tee, the impact triggers the release mechanism to drop the next ball from the reservoir, eliminating the need for external motors or power sources.
Solution Approach 2:
A spring-loaded or gravity-based intermediary mechanism translates the bat strike force into the action of releasing the next ball. This mechanical intermediary converts the impact energy into automated ball loading without requiring electrical components.
4Device complexity
If manual ball loading is used, then device complexity is reduced, but productivity and time efficiency deteriorate
Solution Approach 1:
The tee automatically loads balls using the energy from each bat strike. After the batter hits the ball, the impact triggers the release mechanism to drop the next ball into position, allowing continuous practice without manual intervention and significantly improving productivity.

AI summary
A batting tee system that can be used to both tee a ball for batting and retrieve balls on the ground. As balls are retrieved, the balls are automatically positioned for use in batting. The batting tee system uses a tube body having an interior and an open first end of a first diameter. An expandable constraint is disposed at the first end. The expandable constraint defines a secondary opening that can be selectively altered between a second diameter that is smaller than the first diameter, and a third diameter that is larger than the first diameter. A mechanical activator is used to alter the secondary opening of the expandable constraint between the second diameter and the third diameter. This controls the passage of balls out of the tube body.
