Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Players, both beginners and experienced, face difficulty in mastering the skill of applying spins to table-tennis balls due to the short contact time and complexity of ball movement, making it challenging to effectively practice and improve this essential skill in table-tennis games.
Innovation Solution
A table-tennis training apparatus featuring a rotatable ball holder with an elastic structure that dampens the ball's speed after being hit, allowing for prolonged contact time and facilitating the experience of applying spin, comprising a Y-shaped wire structure and a telescopic post with a suction cup mounting system, enabling adjustable angles and continuous practice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If players use a racket to hit the table-tennis ball to apply spin, then the ball trajectory and bounce direction can be controlled, but the contact time between racket and ball is very short making it difficult to master the skill
Solution Approach 1:
The ball holder pre-positions the ball at a specific location and orientation before the player strikes, allowing the player to focus on spin application technique rather than ball positioning. The ball is held stationary in optimal position until struck, ensuring consistent starting conditions for each practice stroke.
Solution Approach 2:
The ball holder acts as an intermediary device between the player's racket and the ball, providing a controlled interface that extends the effective interaction time. The mechanical structure with elastic element mediates the energy transfer and maintains ball-racket contact longer than a free-flying ball would allow.
2Stability of the object's composition
If the ball holder is held stationary, then the ball position is stable, but the player cannot experience the dynamic motion of a real rallying scenario
Solution Approach 1:
The ball holder transitions from a static support structure to a dynamic responsive system. The elastic element allows the holder to move and rebound when struck, simulating the motion of a real ball during rally while maintaining positional stability before impact. This dynamic behavior provides realistic training feedback.
Solution Approach 2:
The system changes its mechanical parameters (stiffness, damping, mass) through the elastic element to balance stability and responsiveness. The elastic structure allows controlled displacement and restitution, changing the ball holder's behavior from completely rigid to dynamically responsive based on the strike force and angle.
3Ease of operation
If players practice with a moving ball in real rallying, then the training is realistic, but the complex ball movement and short contact time make it difficult to focus on spin application
Solution Approach 1:
The invention extracts the spin application skill from the complex context of full rallying and isolates it for focused practice. By using a stationary or minimally moving ball holder, the training removes the variables of ball trajectory control and timing, allowing the player to concentrate exclusively on grip, racket angle, and spin generation techniques.
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 allows players to more effectively practice applying spins by prolonging the contact time between the racket and ball, enhancing the training experience and increasing efficiency, enabling improved skill mastery through simulated rallying scenarios.
Implementation Method 1
an elastic structure coupled to the ball holder for, after the ball held on the ball holder is hit by a racket, dampening the speed of the ball holder and resetting the ball holder to an initial position
Implementation Method 2
an elastic structure coupled to the ball holder for, after the ball held on the ball holder is hit by a racket, dampening the speed of the ball holder
Implementation Method 3

AI summary
A table-tennis training apparatus for training a player to apply spin to a table-tennis ball when using a racket to hit the ball. The table-tennis training apparatus has a ball holder for rotatably holding a table-tennis ball. When the ball thereon is hit by a racket, the ball holder pivots about an axis and an elastic structure coupled to the ball holder dampens the speed of the ball holder to prolong the contact time between the racket and the ball and consequently help the player to more clearly experience the feeling of applying spin to the ball and thus facilitate the player's training of applying spins to the ball.
