Tethered Ball Training Device for Tennis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training tools for paddle sports, such as tennis, face limitations in space, time, and equipment availability, particularly for beginners or younger players, who struggle to develop hand-eye coordination effectively.
Innovation Solution
A training device that attaches a ball to a tether, allowing users to adjust the distance of the ball based on their height and arm length, enabling continuous practice without a partner or additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a tennis machine is used to shoot balls toward the player, then continuous practice is enabled, but the device is large and expensive and requires retrieving balls after practice
Solution Approach 1:
The invention extracts only the essential function of ball projection by using a simple tethered ball system attached to the player's body, eliminating the need for large mechanical projection devices and ball retrieval operations. The ball is held at a fixed distance from the player through the tether mechanism, allowing continuous practice without external equipment.
Solution Approach 2:
The training device is self-contained and attaches directly to the player's body, making the player themselves the anchor point for the training system. The ball is automatically repositioned after each stroke as the player moves, eliminating the need for external ball retrieval or repositioning operations.
2Ease of operation
If a tee-type device is used to hold the ball, then the ball is stationary for practice, but the device may damage the tennis racquet and tee due to repeated striking
Solution Approach 1:
The invention transitions from a static tee structure to a dynamic tethered ball system that moves with the player. The ball is attached to the player's body via a tether, allowing it to be repositioned automatically after each stroke without requiring a stationary support structure that could be damaged.
Solution Approach 2:
The tether acts as an intermediary between the ball and the player's body, allowing the ball to be held at a fixed distance without direct contact with a rigid support structure. This eliminates the need for a tee that could be damaged by repeated racquet strikes.
3Manufacturing precision
If the ball is held at a fixed distance from the player, then consistent practice geometry is achieved, but the device cannot accommodate different player heights and arm lengths
Solution Approach 1:
The horizontal arm is made adjustable in length, allowing the ball to be positioned at different distances from the player based on their height and arm length. This adjustability maintains the fixed distance geometry needed for consistent practice while adapting to different player dimensions.

AI summary
The present disclosure includes a training device for practicing a hitting a ball with a racquet or paddle. The training device includes a base, a vertical arm extending from the base, a horizontal arm coupled to the vertical arm, a tether coupled to the horizontal arm, with a ball coupled to an end of the tether distal from the horizontal arm. The horizontal and vertical arms may be adjusted to increase or decrease their length as needed. The tether may also be extended or shortened to position the ball at the desired height for practice. The base is adapted to be received in the laptop compartment of a backpack to secure the base to a user.
