Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tethered baseball device is used for hitting practice, then the ball can be easily retrieved and space for gameplay is reduced, but friction hinders the ability to accurately evaluate hitting skills
Solution Approach 1:
The spherical object is segmented with multiple orifices distributed across its surface, allowing selective attachment of cords at different locations. This segmentation enables the ball to rotate freely about the cord attachment axis while maintaining tethered operation, reducing friction-induced measurement errors and improving hitting skill assessment accuracy.
2Area of stationary object
If a conventional tethered ball is used, then space for gameplay is limited, but friction from the tether prevents realistic trajectory simulation
Solution Approach 1:
The spherical object is designed to rotate dynamically about the cord attachment axis during flight. This rotational freedom allows the ball to simulate more realistic trajectory patterns compared to conventional tethered balls, improving reliability of trajectory simulation while maintaining compact playground space requirements.
3Reliability
If a spherical object with interior anchor and rotating mechanism is used, then friction is reduced and trajectory realism is improved, but device complexity increases
Solution Approach 1:
The cord attachment mechanism is nested within the spherical object, with the interior anchor positioned inside the ball and the cord passing through orifices in the spherical surface. This nesting approach allows the rotation mechanism to be integrated within the ball structure rather than adding external components, reducing overall device complexity while maintaining trajectory simulation reliability.
