Ball Spinner Device Stabilizing Gyroscopic Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to effectively spin a ball about an axis and transfer it to a holder due to wobbling or loss of spin, making it difficult for users to achieve a stable spinning ball.
Innovation Solution
A ball spinner device with a base and multiple ball supports, including wheels or omnidirectional casters, and a support member that allows the ball-engaging member to be positioned at the top center of the ball for stabilization, using a direct-drive motor or power tool to drive rotation, and featuring movable parts for accommodating different ball sizes and easy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a ball is supported on three wheels to allow spinning, then the ball can be rotated, but the ball wobbles or fails to spin about an axis
Solution Approach 1:
A support member is introduced as an intermediary element that contacts the ball at its top center. This support member stabilizes the ball during spinning by providing a reference point that prevents wobbling, while still allowing the ball to rotate. The support member acts as a mediator between the ball supports and the ball, ensuring stable rotation about a fixed axis.
2Ease of operation
If a ball is spun using support wheels, then the ball can rotate, but it is difficult to transfer the ball onto a holder in line with the spin axis
Solution Approach 1:
The support member serves as a mediator that maintains the ball's alignment with the spin axis during transfer. By contacting the ball at its top center, the support member ensures that the ball remains properly oriented, making it easier to transfer onto a holder in line with the spin axis while maintaining alignment precision.
Solution Approach 2:
The support member is positioned to contact the ball before spinning begins. This preliminary positioning ensures that the ball is already aligned with the spin axis and stable, making the subsequent transfer operation easier and more precise. The ball is prepared in advance for the transfer operation.
3Ease of operation
If a ball is manually balanced on a finger or holder, then spinning can be achieved, but it is difficult for learners to get the ball spinning and onto the holder
Solution Approach 1:
The device enables the ball to spin itself through the interaction between the support member and the ball supports. The support member contacts the top center of the ball and, when actuated, causes the ball to rotate about its axis automatically. This self-service mechanism eliminates the need for manual balancing skills, making it easy for learners to achieve stable spinning without complex manual coordination.
