Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ball is fixed rigidly at the end of the support bar, then the mounting is stable, but the ability to simulate various game situations and stroke techniques is limited
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid fixed mounting with a dynamic elastic extension system. The elastic extension allows the ball to move elastically in response to racket strokes while maintaining connection to the support bar, enabling simulation of different stroke techniques and game situations while preserving mounting stability through the elastic restoring force.
Solution Approach 2:
The patent changes the physical state parameter of the ball mounting from rigid to elastic. By introducing an elastic extension between the ball and support bar, the system transforms from a fixed rigid connection to a flexible elastic connection, allowing the ball to move in different directions while maintaining stable mounting through elastic properties.
2Adaptability or versatility
If the ball is allowed to move freely in multiple directions, then different stroke techniques can be trained, but the mounting becomes less stable
Solution Approach 1:
The patent changes the physical state parameter of the ball mounting from rigid to elastic. By introducing an elastic extension between the ball and support bar, the system transforms from a fixed rigid connection to a flexible elastic connection, allowing the ball to move in different directions while maintaining stable mounting through elastic properties.
Solution Approach 2:
The patent applies the dynamics principle by replacing the rigid fixed mounting with a dynamic elastic extension system. The elastic extension allows the ball to move elastically in response to racket strokes while maintaining connection to the support bar, enabling simulation of different stroke techniques and game situations while preserving mounting stability through the elastic restoring force.
3Ease of operation
If an exchangeable connecting member is used to allow different ball positions, then the device complexity increases, but the ease of operation for training different shots improves
Solution Approach 1:
The patent applies segmentation by dividing the ball mounting system into separable components: a connecting member with an elastic extension that can be attached to and detached from the support bar. This segmentation allows the connecting member to be exchanged to change ball position and movement characteristics, facilitating training of different shots while keeping the overall system manageable through modular design.
Solution Approach 2:
The connecting member serves multiple functions: it provides elastic support for the ball, allows exchangeable mounting to adjust ball position, and enables training of various stroke techniques. This multi-functionality improves ease of operation for training different shots while avoiding excessive complexity by using a single versatile component rather than multiple specialized ones.
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
Enables better training of different stroke techniques by allowing the ball to move and be positioned in multiple directions, providing a stable and adjustable mounting system that facilitates the practice of various shots, including slice serves and topspin, enhancing the realism and effectiveness of training.
Implementation Method 1
an elastic extension is mounted at the ball, through which the ball is fixed movably in different directions at the connecting member, by means of which, during the stroke of a tennis racket against the ball, the ball can move in different directions
Implementation Method 2
a tension element is mounted at the ball or at the radially protruding elastic extension, which tension element can be formed, for example, in the shape of a hook, which can be hooked onto the support bar in spaced openings. The tension element can be connected to the ball by a rubber band in order to keep the ball under tension in its initial position
